Do you know the tank hydraulic jacking system?Understand it?Do you know how it jacked up the tank?And do you know how much weight it can lift? Although hydraulic jacking system have been widely used in the construction of large tanks, many people still know little about them. Today I will give you a good introduction to the hydraulic jacking system from the following aspects.
●What is the hydraulic jacking system?
●How does the hydraulic jacking system lift the tank?
●How much weight can the hydraulic jacking system lift?
Hydraulic jacking system is an important machine for tank construction. The equipment is mainly used for inverted construction of vertical cylindrical steel tank (hydraulic lifting method) in petrochemical industry, inverted construction of steel liner in power plant chimney and inverted construction of vertical cylindrical low temperature tank.
At present, we have three types of hydraulic jacking system in WINCOO Engineering Co., LTD. They are the following three: Advanced hydraulic jacking system, Simple unfixing Holding -latch hydraulic Jacking system and Simple chain type hydraulic jacking system.
Hydraulic jacking system (package unit) is evenly distributed around tank inner wall. Tank top and upper (the first layer) wall plates are lifted first and then install and weld wall plates of tank body. Self locking hydraulic jacking system and hydraulic hoist composing of lifting frame and lifting rod are adopted. When oil enters hydraulic jacking system, upper clamp fastens and lifts lifting rod and expansion ring and mobilize tank (including tank top) to ascend upward. When oil returns to jack, upper clamp returns with piston and lower clamp automatically fastens lifting rod without gliding. The jack repeats the movement and make lifting rod ascend with tank to designated height (spare height for next layer of plate). After butt weld of next layer of wall plates, open upper and lower loosening device and loosen upper and lower clamp to make lifting rod and expansion ring descend to lower expanded and welded rib plate of the next layer of wall plates and then lift. Repeat the process and ascend welded tan till the last layer of wall plates are installed and welded. The installation of the whole storage tank is completed.
1.The number of hydraulic cylinders used for the same size tank is different according to the actual use and weight of the tank.
2.Regardless of tank size, hydraulic cylinder installation must be evenly distributed.
3.Construction of different tanks and selection of YT series hydraulic lifting equipment number and calculation of lifting equipment load rate specification: lifting equipment load rate must be less than 80%.
For example, for a storage tank with a volume of 50,00m3 and a diameter of 60m, the maximum weight of the lifting body of the tank is 536T (excluding the weight of the bottom plate of the tank), 40 hydraulic cylinders of YT25-2700 are selected, and the output force of each hydraulic cylinder is 250KN, so the total output force of the lifting device is 25O×40=10000KN.The load rate of the lifting equipment is 536x9.8÷10000×100%≈52.53%, which meets the requirement of less than 70%.
The above is our brief introduction to the hydraulic jacking system. If you have any questions, you are welcome to browse other relevant articles and products on our website. I hope the above content will be helpful to you.
Hydraulic jack is mainly used in the inverted construction of vertical cylindrical steel storage tank (hydraulic lifting method) in petrochemical industry, inverted construction of steel liner in power plant chimney and inverted construction of vertical cylindrical low temperature storage tank, etc. Today I will introduce our YT series hydraulic jack, and take the YT30 for example.

2.The equipment adopts PLC program to control the lifting centrally. Each lifting pump station is equipped with displacement sensor device, which is easy to operate and has high lifting synchronization accuracy.The equidistant distance can be adjusted arbitrarily.
3.The hydraulic lifting pump station can be divided into two modes: dynamic and centralized control. The hydraulic cylinder can be adjusted (fine-tuning) rising and falling individually or locally (several), and can be controlled centrally by multiple groups. The lifting height can be more accurately controlled, which is convenient for the butt adjustment of the welding seam of the tank wall.
4.Each hydraulic cylinder is equipped with safety valve, good self-locking,equipment will not be due to power failure in the process of operation;
5.The blasting and breaking of a high-pressure rubber hose.The failure of a hydraulic cylinder causes the tank or heavy weight to slide or fall, and the hydraulic lifting process is safe and reliable.
6.The stroke of hydraulic cylinder is 3200mm, which can meet the one-time lifting completion of the existing panel width and reduce the lifting time.
7.The overall base length of the equipment is only 2200mm, which can fully meet the automatic welding process of large storage tank inner ring seam.

1.Liquid level meter shows the oil level and liquid temperature in the box.
2.The air filter has the function of protecting and purifying the gas of hydraulic oil.
3.The lifting lug is used for equipment lifting.
Hydraulic system is the power source of the whole hydraulic lifting equipment, first with the motor todrive the piston pump, and then the mechanical energy of the pump into pressure energy, through the pressure valve (relief valve), direction valve (solenoid valve), sent to the actuator (hydraulic cylinder), and finally converted into mechanical energy to drive the load.
1.Protective cover can be disassembled, it mainly protect all parts under the protective cover .
2.Electromagnetic directional valve through the electromagnet with electricity and no electricity to complete the lifting action of the hydraulic cylinder.
3.The relief valve can control the pressure of the system to maintain constant by adjusting the handle of the relief valve, and realize the function of regulating, stabilizing or limiting the pressure.The set of equipment relief valve setting range (0-31.5mpa).
4.Pressure gauge shows the system pressure value.
5.The high-pressure ball valve makes the hydraulic oil flow or cut-off in the system. The valve mainly plays a safety protection role in this set of equipment.. It prevents the internal leakage of the hydraulic valve from affecting the operation of the hydraulic cylinder's descending equipment. Hydraulic fluid flow or cut-off is controlled by rotating high pressure ball valve handle.
1.Hydraulic cylinder is the actuator, rated output force is 250kN.
2.The hydraulic cylinder roof device is the force fulcrum of the piston rod end of the hydraulic Cylinder. In the process of lifting the tank, to prevent the damage of the hydraulic cylinder caused by the bending of the piston rod, or even failure and safety accidents.
3.Adjust the jacking bolt to adjust the gap between the hydraulic cylinder bracket and the tank wall, and tighten the bracket in the process of lifting the tank.
4.The hydraulic cylinder support regulating rod can mainly meet the requirements of resistance to class 5 wind load and tank partial load during the tank lifting process. It can also assist in adjusting the gap between hydraulic cylinder bracket and tank wall when rising circle falls back.
5.The equipment adopts PLC equalization system with automatic and manual modes.And the man-machine control interface is set on the control cabinet.The displacement sensor transmits signals to adjust the equipment at the same height
6.The working principle of the displacement sensor: because the wire rope is wound on a pulley built into the sensor, and the other end of the sensor has been connected to the mechanical movement, which is equipped with a display, so when the wire rope is pulled, the mechanical movement can be converted into electrical signals, so as to get the required data.
7.Unidirectional explosion-proof valve is a safety valve that allows the hydraulic cylinder to self-lock.In the process of being lifted or in the process of hanging the tank, the tank will not slide or fall because of the sudden explosion of the high-pressure hose, blurting, sudden power failure, etc.

In recent years, large-scale pipeline projects have started one after another, and the level of mechanical equipment of pipeline construction solutions has been steadily improved. However, the management of pipeline construction equipment on the construction site has not kept up with the speed of pipeline engineering and mechanical equipment updates, resulting in a high rate of equipment failure and maintenance on the construction site. High cost, low technical performance and low utilization rate. In response to these situations, explore standardized maintenance in the management of pipeline construction equipment.
Here is the content list:
l Regarding the maintenance status of pipeline construction equipment at the construction site.
l What are the specific measures to achieve standardized maintenance of pipeline construction equipment?
l How can companies ensure the effective implementation of pipeline construction equipment maintenance procedures?
l Objective conditions cause pipeline construction equipment maintenance to be unable to be carried out normally. Pipeline construction has a large geographic span, harsh construction environment, and increased equipment component wear, which directly affects the stability and reliability of the equipment, causing the mechanical equipment to lose basic performance and fail to operate normally. In addition, the current project schedule is very tight. In order to catch up with the schedule and grab the schedule, it is difficult to keep up with the daily maintenance of pipeline construction equipment.
l Subjectively neglect.The subjective factor that causes the on-site pipeline construction equipment maintenance to be unable to be carried out normally is that the relevant units and management personnel do not pay attention to the equipment management. In many construction companies, the management of the company, project management, and construction crews do not pay much attention to the management of pipeline construction equipment, believing that the equipment is just a tool for wear and tear during the construction process, which emphasizes use rather than maintenance. Many construction projects and construction units arbitrarily extend the maintenance cycle of pipeline construction equipment, reduce the grade of accessories and lubricants, so that the overhaul cycle of the engine is shortened due to human factors, project maintenance costs increase, and the cycle of equipment failures is prolonged. The technical performance of pipeline construction equipment has severely declined.
l Weak technical management capabilities.The quality of equipment maintenance has declined. First of all, many on-site management personnel's understanding of on-site maintenance of pipeline construction equipment is still at the level of "replacement of the three oil filters", and the maintenance of the engine, chassis and working devices is not included in the pipeline construction equipment. Maintenance plan in progress. Secondly, the equipment operators and maintenance personnel do not have a high level of basic skills and cannot complete the overall overhaul of pipeline construction equipment with high quality.
Repair and maintenance of pipeline construction equipmentt is very important. First of all, we must regularly check, maintain and replace vulnerable parts. WINCOO will provide manuals with the machine, such as high-performance pipeline construction equipment, automatic pipeline construction equipment, small pipeline construction equipment, high-precision pipeline construction equipment, easy-to-maintain pipeline construction equipment, etc. The following are specific measures:
① In view of the low maintenance quality of pipeline construction equipment, by compiling comprehensive, meticulous, and highly operable procedures, not only can we clarify what tasks the pipeline construction equipment operators and maintenance personnel need to do daily maintenance and secondary maintenance, but also tell them How to work.
② While compiling maintenance procedures for pipeline construction equipment, the company also compiled checklists for standardized maintenance and management of various types of pipeline construction equipment, making it the main basis for management departments at all levels to inspect pipeline construction equipment, and unify inspection standards and assessment scores. Standards to facilitate the recording, filing and review of equipment inspections and inspection results.
① Personnel training. Strengthen the learning and training of pipeline construction equipment supervisors,managers, and maintenance personnel to change their concepts, fully understand the importance of maintenance to the use of equipment, and cultivate long-term perspectives and implementation of pipeline construction equipment maintenance, and completely avoid the first phase The situation where the project "eaten" a batch of pipeline construction equipment. Through regular learning and training, the standardized equipment maintenance procedures are deeply rooted in the hearts of the people, and become the working guidelines and working habits of operators and repairers, rather than the work requirements of the superior management department. Through learning and training, to a certain extent, the sense of responsibility and dedication of managers at all levels has also been improved.
② Innovate the system of deciding people and machines. In order to mobilize the enthusiasm of equipment operators to rationally use pipeline construction equipment, earnestly maintain pipeline construction equipment, and sincerely care for pipeline construction equipment, the company strictly implements the system of determining personnel and equipment, and integrates the personnel and equipment management information system to control the attendance and equipment of the operators. The intactness of the pipeline construction equipment is linked together, and the man-hours for equipment maintenance are included in the actual man-hours of the operator.
① Increase the intensity of rewards and punishments for pipeline construction equipment inspection. In order to ensure the implementation of the standardization of pipeline construction equipment on-site maintenance, the company pays special attention to the intensity of inspection rewards and punishments for pipeline construction equipment when revising the management system.
② Link the maintenance of pipeline construction equipment with bonuses. In order to motivate the construction unit to use and maintain the pipeline construction equipment, the project department regards equipment maintenance as an important assessment index when formulating the economic responsibility system assessment, guiding the construction unit to use the maintenance pipeline construction equipment rationally, controlling the construction progress and avoiding the problem to the greatest extent.
In order to ensure that pipeline construction equipment maintenance procedures can be effectively implemented, the company has formulated corresponding management systems and adopted specific measures to supervise the implementation of these systems.
l Divide maintenance responsibilities. In the management system, the corresponding responsibilities of equipment operators, pipeline construction equipment maintenance personnel, unit equipment managers, and project pipeline construction equipment managers are clarified, and these responsibilities are written into the maintenance procedures manual of each type of equipment, so that all levels of pipeline construction equipment Managers can see what they should do every day and how to record their work in the maintenance procedures.
l Promote standardized pipeline construction equipment maintenance procedures. Implement standardized equipment maintenance organization processes in each construction project to ensure smooth equipment maintenance channels and optimize the maintenance force of the entire project.
l Establish a professional maintenance team. The project department mobilizes skilled fitters, electricians, and repairers to form a professional maintenance team, which is conducive to the unified scheduling of maintenance forces for the project, and ensures low failure rate and high utilization of pipeline construction equipment.
What is more? WINCOO provide not only pipeline construction solutions, but also pipe spool fabrication solutions for customers from everywhere!
The EGW welding used by the tank welding machine is gas-electric vertical welding, which is a gas-shielded arc welding method developed from ordinary gas-shielded gas welding and electroslag welding. The advantages are high productivity and low cost. The main difference with narrow gap welding is that the weld is formed in one pass, rather than multi-pass multi-layer welding.
What is the operation method of tank welding machine?
What are the technical features of tank welding machine?
What is the development trend of tank welding machine?
What is the operation method of tank welding machine?
(1) Left welding method (right→left): small residual height, large width and small splash, which is easy to observe the welding seam, the welding process is stable, the gas shielding effect is good, but the depth of dissolution is shallow.
(2) Right welding method (left→right): The remaining height is large, the width is small, and the splash is large, which is convenient for observing the molten pool and the depth of the molten metal.
(3) Gun delivery method: zigzag swing.
(4) Flat fillet welding does not swing or swing slightly.
(5) The vertical angle is welded upward, and the triangular gun is used.
(6) Welding torch transition: stay on both sides of the molten pool and transition at the front 1/3 of the molten pool.
(7) Gun angle: perpendicular to the weld bead, at an angle of 80-90° along the direction of the gun.
(8) Test plate: the gap is 2.0-2.5mm, and the arc starting point is slightly smaller than the arc ending point. No blunt edge, anti-deformation 1°.
(9) To prevent defects: prevent the angle from melting - burn through the angle. No fusion between layers - pay attention to the gun angle.
The direction of the arc axis of the tank welding machine is perpendicular to the direction of the penetration depth of the weld. During welding, a water-cooled copper slider is used on the front of the weld, and a water-cooled gear row (or pad) is used on the back of the weld. The flux-cored wire is fed into the weldment and in the groove formed by the stopper, the four sides of the molten pool are constrained to realize single-sided welding and double-sided forming at one time. Tank welding machine is a high-efficiency welding technology and equipment.
In recent years, the promotion and application of tank welding machine in engineering has achieved good results, and in-depth research on the fusion welding mechanism of gas-electric vertical welding technology. Tank welding machine has good welding quality, high deposition speed and low comprehensive cost, which provides a broad prospect for the popularization and application of this efficient automatic welding technology and equipment.
With a large number of suppliers, we can choose the right suppliers according to customers' requirements and provide the most cost-effective tank welding machines. For more information, please connect WINCOO ENGINEERING CO., LTD.
