Common problems when using tank hydraulic jacking system.

Reasons for leakage of tank hydraulic jacking system.

(1) Caused by defects in design and manufacturing

(2) Impact and vibration cause loose pipe joints

(3) Mutual wear of dynamic seals and matching parts (especially hydraulic cylinders)

(4) The oil temperature is too high and the rubber seal is incompatible with the hydraulic oil and deteriorated.

Combining the above problems, talk about the measures to control the leakage of tank hydraulic jacking system.

l Solution 1: Design and manufacturing defect solutions

The selection of external components of tank hydraulic jacking system often plays a decisive role in the leakage of hydraulic system. This determines that in the improvement of tank hydraulic jacking system, our technicians should carefully choose the cylinders, pumps, valves, seals, hydraulic accessories, etc. based on the principle of choosing the best among the best and choosing the cheap.

①　Reasonably design the mounting surface and sealing surface of the tank hydraulic jacking system. When the valve block or pipeline is fixed on the mounting surface, in order to obtain a satisfactory initial seal and prevent the seal from being pushed out of the groove and being worn.

②　The installation surface of the tank hydraulic jacking system should be straight and the sealing surface should be finished. The surface roughness should reach 0.8μm and the flatness should reach 0.01/100mm. The surface must not have radial scratches, and the pre-tightening force of the connecting screw must be large enough to prevent surface separation.

③　During the manufacturing and transportation of tank hydraulic jacking system, it is necessary to prevent the key surface from bumping and scratching. At the same time, the assembly and debugging process must be strictly monitored to ensure the quality of assembly.

④　Do not be taken lightly about the leakage of some tank hydraulic jacking system, and must be eliminated.

l Option 2: Reduce shock and vibration

In order to reduce the leakage of tank hydraulic jacking system caused by the loosening of pipe joints subjected to shock and vibration, the following measures can be taken:

①　Use shock-absorbing brackets to fix all pipes to absorb shock and vibration;

②　Use low-impact valve or accumulator to reduce the impact;

③　Properly arrange pressure control valves to protect all components of the tank hydraulic jacking system;

④　Minimize the number of pipe joints used, and try to use welding to connect pipe joints;

⑤　Use straight threaded joints, tee joints and elbows instead of tapered pipe threaded joints;

⑥　Try to replace each piping with oil return block;

⑦　For the highest pressure used by the tank hydraulic jacking system, specify the bolt torque and plug torque during installation to prevent the joint surface and seal from being eaten away;

⑧　Install the pipe joints of the tank hydraulic jacking system correctly.

l Option 3: Reduce the wear of dynamic seals

Most of the dynamic seals have been precisely designed. If the dynamic seals are qualified, installed correctly, and used reasonably, they can guarantee a long-term relatively leak-free work. From the perspective of tank hydraulic jacking system design, designers can take the following measures to extend the life of dynamic seals:

①　Eliminate the side load on the piston rod and drive shaft seal;

②　Use dust ring, protective cover and rubber sleeve to protect the piston rod to prevent abrasives, dust and other impurities from entering;

③　Design and select a suitable filter device and a fuel tank that is easy to clean to prevent dust from accumulating in the oil;

④　Keep the speed of the piston rod and shaft as low as possible.

Matters needing attention when using tank hydraulic jacking system.

First of all, the requirements for static seals,tank hydraulic jacking system static seals prevent oil leakage between rigid fixed surfaces. Reasonably design the size and tolerance of the seal groove, so that the installed seal will be deformed to a certain extrusion so as to fill the microscopic depression of the mating surface and increase the internal stress of the seal to be higher than the pressure to be sealed.

It should be noted that when the rigidity of the part or the pre-tightening force of the bolt is not large enough, the mating surface will separate under the action of the oil pressure, causing a gap or increasing the gap that may exist from the beginning because the sealing surface is not flat enough. As the mating surface moves, the static seal becomes a dynamic seal. Rough mating surfaces will wear the seal, and the fluctuating gap will eat away at the edge of the seal.

In addition, control the oil temperature to prevent deterioration of the seal. Premature deterioration of the seal may be caused by many factors. An important factor is the high oil temperature. Each time the temperature rises by 10°C, the seal life will be halved. Therefore, a reasonable design of an efficient tank hydraulic jacking system or a forced cooling device should be provided to keep the optimal oil temperature below 65°C.

Among them, engineering machinery of tank hydraulic jacking system must not exceed 80°C, and hydraulic oil and seal types and materials should be selected according to the operating instructions or relevant manuals to solve compatibility problems and extend the service life of seals.

What is the process of using the orbital welding machine?

(1) Preparation of welding parts: Considering the high hardness of the rail steel, it is difficult to process the groove on site. Therefore, the orbital welding machine adopts the docking method and uses the existing end face of the rail as the operation surface. If the end face is seriously corroded, it is necessary to use the angle Grinding can polish the surface brightly.

(2) Determining the butt gap: Considering the height of the rail itself, the gap cannot be too small, otherwise the welding rod cannot be penetrated into it for welding operations, so it is necessary to reserve enough gap.

(3) Weldment preheating: In the preheating process of orbital welding machine, a gas welding torch is used for preheating, and an infrared temperature measuring gun is used to ensure that the preheating reaches the specified temperature.

(4) Butt surfacing process: The whole welding process adopts the welding method of multi-layer multi-pass welding. Although this method is relatively inefficient, it can ensure the welding strength and the temperature between layers.

(5) Post-weld heat treatment: Orbital welding machine heating method uses gas welding torch. After heating to the specified temperature, asbestos felt is used for heat preservation to prevent cracks from appearing after welding.

(6) Grinding of workpiece after welding: Orbital welding machine keeps the weld and rail base metal smooth.

What are the features of the orbital welding machine?

The biggest feature of orbital welding machine is local small-scale heating, high heating efficiency, easy to use, very suitable for rapid heating and cooling of high manganese steel welding, and also suitable for welding repair of local defects of rails. It is currently the most widely used in rail and rut welding repair methods. But it must be noted that the orbital welding machine must be properly preheated for rail welding. Because of the local heating and rapid cooling of the rail, it is easy to produce abnormal brittle structures such as martensite and bainite, which increases the brittleness of the rail. Preheating prevents abnormal tissue formation.

What is the using principle of the orbital welding machine?

Using pipe fixed, welding carriage walking to reach all position automatic pipe welding, welding process with high efficiency and low cost of CO2 gas shielded welding. Pipeline all position automatic welding machine consists of welding control system, welding carriage with torch, welding power source, wire feeding device and accessories.

Wincoo Engineering Co., Ltd has worked on the production of orbital welding machines for over ten years. You can find the best orbital welding machine in this company.

Hydraulic storage tank lifting equipment consists of oil chamber, oil pump, oil storage chamber, piston, crank handle, oil valve and other main parts. When working, as long as the crank handle is moved back and forth, the manual oil pump continuously presses oil into the oil cylinder. Due to the continuous increase of the oil pressure in the oil cylinder, the piston and the weight on the piston are forced to move upward together.

What are the precautions for the use of hydraulic storage tank lifting equipment?

1. Hydraulic jacks cannot be used as permanent support equipment. For long-term support, the support part should be added under the heavy object to ensure that the hydraulic jack is not damaged.

2. If only one hydraulic storage tank lifting equipment is used to lift one end of the heavy object, the hydraulic storage tank lifting equipment should be placed on the symmetrical axis of the heavy object, and the long direction of the hydraulic jack base and the easy toppling of the heavy object should be made. the same direction. If two hydraulic jacks are used at one end of the heavy object, the direction of the base should be slightly symmetrical and placed on both sides of the symmetrical axis of the heavy object.

3. When two or more hydraulic storage tank lifting equipment are used to lift at the same time, they must be commanded, coordinated, and lifted at the same time.

4. Hydraulic storage tank lifting equipment should be stored in a dry and dust-free place. It is not suitable for use in workplaces with acid, alkali and corrosive gases, and it should not be placed outdoors in the sun and rain!

What are the structural parts of hydraulic storage tank lifting equipment?

The hydraulic storage tank lifting equipment is a piston type lifting equipment, consisting of a hydraulic control cabinet (pumping station), the main bearing of the high-pressure oil pipe, the accessories of the hydraulic pump system, the oil control valve, the piston jack, the ring wire rope hanger, and the pumping station by two independent Composed of a hydraulic lifting unit and a centralized electrical control cabinet, it can serve the lifting of two 10000m³ tanks at the same time. Each 10000m³ tank is equipped with 20 jacks. The total composition of the hydraulic oil pipe is distributed in two stages, and then the hydraulic oil is sent to the hydraulic jack. Short construction period, low cost and good economic benefits are its significant advantages.

What should be paid attention to before using hydraulic storage tank lifting equipment?

1. Before lifting, put the slotted end of the handle into the oil return valve stem, and tighten the oil return valve stem clockwise.

2. The handle of hydraulic storage tank lifting equipment is inserted into the handle hole and pressed up and down, and the piston rod will rise steadily to lift the heavy object. Due to the limiting device in the jack, it will not rise when it reaches a certain height.

3. To lower the piston of hydraulic storage tank lifting equipment, just use the slotted end of the handle to slightly loosen the oil return valve rod counterclockwise (no more than 2 turns), and the piston rod will gradually descend. If there is a load, the oil return valve stem should not rotate too fast, otherwise it will be dangerous if the descending speed is too large.

It is not easy to maintain pipe spool fabrication line. Whether it is used in the oil and gas industry, power plants, chemical plants or other infrastructure projects, the pipe spool fabrication line usually contains hundreds of components and thousands of processing steps. Therefore, it is very important to maintain the pipe spool fabrication line.

Here is the content list:

l Line maintenance

l Pipeline repair

l The advantages of choosing WINCOO to repair and maintain the tube shaft production line.

Line maintenance

The maintenance of the pipe spool fabrication line includes inspection of pipeline corrosion and anti-corrosion; inspection of pipelines for oil leaks; inspection of valves along the line; inspection of the loss of hydraulic structures and coatings along the line; inspection of signs of damage, etc. Once the pipeline line and equipment are found to be faulty, the pipe spool fabrication line should be repaired or updated in time.

Due to the long line of the pipe spool fabrication line, it may be damaged by man-made and natural disasters at any time. Therefore, it is necessary to conduct line inspection and maintenance of the pipe spool fabrication line frequently. In addition, there is also a dedicated pipeline maintenance team equipped with necessary mobile equipment, earth moving equipment, welding and blocking equipment, and communication tools, so that they can be prepared for emergency repairs at any time.

l Pipe spool fabrication line anti-corrosion inspection

Routine pipe spool fabrication line anti-corrosion inspections include: regularly testing the protection potential along the pipeline; using an anti-corrosion layer detector to check the integrity of the pipe's anti-corrosion layer on the ground. The inspection of corrosion in the old pipeline is a complicated task, and it is usually carried out with a cup-type pipe cleaner with a testing instrument.

The testing equipment of the pipe spool fabrication line includes a magnetic flaw detector to detect internal corrosion and an ultrasonic thickness gauge to detect the thickness of the pipe spool fabrication line. The running distance is calculated by the number of revolutions of the support wheel, and all the tested parameters are converted into signals and recorded on the tape. After the inspection, the tape is interpreted by the computer, which can indicate the corrosion degree and location of the pipeline.

l Pipe spool fabrication line oil leakage inspection

Mainly rely on line inspectors to inspect the pipe spool fabrication line. In order to ensure the safety of residents and enterprises along the route, all countries have formulated oil and gas pipeline safety technical specifications, which are strictly supervised and implemented by government departments. If leakage occurs in the pipe spool fabrication line, report it to the competent authority immediately and check the cause of the accident on site.

Heavy rains and floods will cause soil erosion on the pipe spool fabrication line and damage to the embankment, resulting in exposed, suspended or even broken underwater pipelines. These situations are mainly discovered by line inspectors. Line patrol personnel usually walk on the ground or fly in the air to patrol the line. The maintenance work of the pipe spool fabrication line must be implemented in accordance with the detailed line engineering as-built drawing!

Pipeline repair

The most prominent part of the maintenance of the pipe spool fabrication line is the handling of large accidents such as leak repair and pipe replacement. If the leak is caused by corrosion and perforation, you can use a fixture to plug the leak on the pipe and then perform repair welding.

If the pipe spool fabrication line is severely damaged or deformed, the pipe must be removed and replaced with a new pipe section. The oil and gas leaked when the pipe is cut off can easily cause a fire. When cutting off the pipeline at low places, it is necessary to prevent a large amount of oil and gas from leaking. Mechanical plugging devices are often used to plug the pipelines, and emergency repair operations are carried out without stopping the transportation.

The mechanical plugging method is to open a hole on the upstream and downstream of the pipe section to be replaced, and insert a plug with a cup into each hole to isolate the oil or gas at both ends, and then drain the oil in the damaged pipe section. Or gas, cut off the pipe section with a mechanical cutter, then insert two pigging balls into the cuts at both ends, and fill the gap between the pigging balls and the plug with nitrogen to prevent explosion during welding.

Put the equipped new pipe spool fabrication line in place, align and weld. After welding, lift the occluder out of the pipe and close the opening to complete the plugging and pipe replacement work. After the pipe spool fabrication line is repaired and operated, two pig balls will be recovered in the pig receiver tube of the downstream station. When plugging and replacing a pipe section, the bypass pipe can be drawn out before plugging to ensure uninterrupted pipe spool fabrication line delivery during the entire pipe replacement process.

The advantages of choosing WINCOO to repair and maintain the tube shaft production line.

Since the pipe spool fabrication line contains thousands of steps, each step is an opportunity for error. Therefore, carefully plan before sending the request for quotation (RFQ) to the manufacturer and proceed during the manufacturing of the pipe spool fabrication line. Careful monitoring and acceleration of the process contribute to successful, timely and profitable results. Adequate planning, preparation and scheduling early in the process is beneficial to project owners, builders and tube and shaft manufacturers!
