Structured compact device, Safe and stable, easy to operate, load adjustable, quick installation, high synchronization accuracy.YT Series Hydraulic Tank lifting device is "dragged five" Oil supply: Each pump station connected to the hydraulic cylinder 5; thus avoiding excessive tubing traditional centralized oil brings. Leakage points more than the disadvantages, to ensure that environmental pollution to a minimum.
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.
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.

What are the characteristics of automatic vertical welder?
What is the working principle of tank welding machine?
What is the working effect of tank welding machine?
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.
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.

How to use a tank welding machine?
l Check the connection
After completing the wiring of the tank welding machine, you must check each installed connector to confirm that it is well connected before starting to operate the equipment. Its contents include:
1. The line connection is correct and reasonable, and the grounding must meet the specified requirements
2. The magnetic work piece gripper shall not have attached metal particles and splashes on its contact surface;
3. The coiled welding cable should be unrolled before use to avoid overheating and insulation damage;
4. When it is necessary to alternately use different lengths of cables, insulating joints should be provided to ensure that useless lengths can be disconnected when not needed.
There must not be any leakage of cooling water, shielding gas or engine oil that affects the safety of welders.
l Work suspension
When the welding work is suspended (for example, during breaks), the output terminal of the equipment or welding machine must be turned off or the power supply must be cut off.
l Mobile welding machine
When you need to move the tank welding machine, you must first cut off the power supply at its input end.
l Equipment not used
The metal electrode and carbon electrode must be removed from the welding tongs when not in use to eliminate the risk of electric shock to personnel or conductive objects. The welding tongs must be placed out of contact with persons, electrical conductors, flammable objects or compressed air bottles when not in use. The welding torch of the semi-automatic welding machine must be properly placed when not in use to avoid accidental activation of the gun body switch.
All arc welding equipment must be maintained at any time and kept in a safe worki
