Welding Rotator for Cylinder- China Factory Suppliers Manufacturers

Hydraulic jacking equipment is a new and special lifting equipment powered by hydraulic oil. By pushing the reciprocating movement of the hydraulic cylinder piston, load conversion is carried out between the upper clamping mechanism connected with the upper end of the piston and the lower clamping mechanism connected with the lower part of the cylinder, so as to realize lifting.The hydraulic jacking equipment is a single-acting two-stage hydraulic cylinder, used for vertical take-off and landing work, return need external force or self-weight back.The equipment is compact, stable, easy to operate, adjustable load, fast installation, high synchronization accuracy.Today we are going to focus on the simple hydraulic jacking system.

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?

What is the hydraulic jacking system?

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.

How does the hydraulic jacking system lift the tank?

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.

How much weight can the hydraulic jacking system lift?

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.

The welding machine for large storage tanks is a kind of tank in which oil, natural gas and other energy sources are stored. Because the tank body is too large, it cannot be shaped at once. It is made of steel plates and spliced together, so a welding machine is required in the splicing process. Although manual welding is the simplest and most direct method, it has high cost and low welding speed. Therefore, the automatic tank welding machine is widely used.

What is the working principle of tank welding machine?

Tank welding machine uses high-energy laser pulses to heat the material locally in a small area. The energy of the laser radiation diffuses through heat conduction into the material and the material is melted to form a specific melting pool. Tank welding machine uses a new type of welding process. Laser welding is mainly aimed at welding thin-walled materials and precision parts, it can spot welding, butt welding, staple welding, seal welding, etc. to realize. The aspect ratio is high and the width of the weld is small. Small heat affected zone, low deformation, fast welding speed, smooth and beautiful weld, no need or easy treatment after welding, high weld quality, no pores, precise control, small focusing spot, high positioning accuracy, easy automation.

What are the characteristics of tank welding machine?

In contrast to the current round welding machines on the market, the tank welding machine of the MSHW series offered by WINCOO Engineering is equipped with a dual drive system as standard. This self-propelled submerged welding system can reduce tank welding time on site by 40%. Welding errors are greatly reduced, saving tank installation costs. The circumferential welding machine is suitable for top-down or bottom-up constructions of single- or double-wall storage tanks for internal and external welding. There are four standard units, but our design allows us to offer custom mounting units for non-standard applications.

What are the characteristics of using tank welding machines?

Horizontal seam welding machine is responsible for welding flat corners and fillet seams in large tank automatic welding machines; therefore, it is also referred to as flat welding machine and fillet seam welding machine. It is used for welding the top and bottom of large pipes and for fillet seam welding. The horizontal seam welding machine uses a special power supply for submerged welding, which can meet the construction environment on site with good welding stability and without interference during operation. The welding power supply can guarantee trouble-free continuous operation for 8-10 years or even 15 years. Equipped with a magnetic adsorption device, it is suitable for welding seams with large angle and wind protection circuits and other tank positions.

With a large number of suppliers, WINCOO ENGINEERING CO., LTD can select the right suppliers according to customers' requirements and offer the most cost-effective tank welding machines. We offer large pressure vessels, high performance pressure vessels, industrial pressure vessels, automatic pipeline construction equipment, electrical solutions for vertical tank construction, etc.
