What are the characteristics of automatic vertical welder?
Automatic vertical welder is high-efficiency automatic welding equipment that uses current feedback closed-loop control of vehicle lift. The thickness of the welded joint can be up to 50mm at one time. Mainly used for thick plate welding in petroleum, chemical, blast furnace, shipbuilding and other industries. EGW vertical gas electric welding machine is a kind of high-efficiency automatic welding equipment improved according to the current feedback closed-loop control welding trolley. The main feature of automatic vertical welder is that the thickness is from 10mm to 50mm in one pass of forced water cooling. At the same time, the molten pool level is automatically controlled, and the wire extension length is automatically adjusted. Small size and light weight welding trolley, flexible and modular, easy to update and easy to use. Widely used in petroleum, chemical, blast furnace thick plate welding and shipbuilding industries.
In most cases, the EGW used in the tank welding machine uses carbon dioxide gas as a protective gas, but sometimes pure argon, argon carbon dioxide mixed gas, argon oxygen mixed gas, and argon helium mixed gas are used. Welding wire is often made of flux wire that creates slag and provides an aesthetically pleasing weld, but sometimes solid wire is used.
Tank welding machine surrounds the molten pool with the base metal end and copper lining or refractory lining material, and can perform vertical upward welding while preventing dripping of molten metal, so it can be welded in a single pass (single operation) Welding of thick plates. Its applications include welding of vertical butt joints such as ship side outer panels, bridge construction, storage tanks, pressure vessels, etc.
What is the working effect of tank welding machine?
Tank welding machine is usually used for welding thicker materials such as low carbon steel and medium carbon steel, and can also be used for welding austenitic stainless steel and other metal alloys. The thickness of the plate is 12~80mm the most suitable. If it is larger than 80mm, it is difficult to obtain a sufficient and good protective effect, resulting in pores in the weld, uneven penetration and incomplete penetration. The length of the welded joint is generally unlimited. Single-layer welding is the most commonly used welding method, but multi-layer welding can also be used.

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.

Simple unfixing Holding -latch hydraulic Jack
Hydraulic lifting device (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 jack and hydraulic hoist composing of lifting frame and lifting rod are adopted. When oil enters hydraulic jack, 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.
Simple chain type hydraulic jack
chain type hydraulic jack is composed of one-stage double-acting hydraulic cylinder, pulley block, load-bearing chain and oil way etc. Moveable pulley is used to enlarge chain stroke, i.e. traveling distance of the cylinder is 1/2 of lifting distance of the chain. It applies to inverted installation and construction of various large tanks (steel) and various tanks.
1. Hydraulic lifting is stable, safe and reliable. Due to the adoption of unified hydraulic control and single or partial (several) adjustment, the whole lifting process is relatively stable. The hoist is provided with synchronizing valve and hydraulic lock to prevent sliding and falling of the tank or heavy loads, which are caused by power failure and fracture of oil tube. Hydraulic lifting is stable, safe and reliable.
2. Construction quality is ensured. As the hoist is provided with synchronizer and adjustable function, lifting height can be controlled accurately. Due to above reasons, quality of the tank is ensured.
3. The equipment is easy to operate. Construction environment is good and work efficiency is high.
4. The equipment is well-adapted. As long as the number of hydraulic hoists is increased or decreased, the whole set of equipment can be applied to the inverted hydraulic lifting construction of large storage tanks with different volumes ranging from several thousand cubic meters to tens of thousands cubic meters.
5. The hydraulic pump station and the hydraulic hoist are placed in the tank for easy operation. Finally, a door-closing plate is reserved to move the equipment out of the storage tank, and the door-closing plate is group welded well.
6. The hydraulic pump station can be controlled singly or jointly, and has strong construction adaptability and excellent technical performance price ratio.
7. Short construction period, low cost and good economic benefit. Due to the high degree of modernization and the fast lifting speed of the complete set of equipment, it has low construction cost and good economic benefit. This technology is truly characterized with convenient and centralized control, simple operation, safety and reliability (no falling), accurate control of weld clearance and lifting height of heavy objects, which can ensure the quality of the project, save labor and reduce costs, and achieve remarkable economic benefits.
