What are the construction steps of advanced tank jacking system?
Advanced tank 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 advanced tank jacking system and hydraulic hoist composing of lifting frame and lifting rod are adopted. When oil enters advanced tank 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.

When using the tank welding machine, the operator puts the lamp tube into the fixture, presses the start button, the two pressing cylinders descend to position the workpiece in the ultrasonic mold cavity, and then the ultrasonic welding head acts to trigger the ultrasonic wave, and the welding head carries out the workpiece. After welding and welding, the cylinder drives the upper die to reset, the pressing cylinder rises, and the operator takes out the workpiece to complete one operation.
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.

Hydraulic storage tank lifting equipment plays a very important role in handling heavy objects. The lifting effect is very good. It is more suitable for lifting heavy objects with a low height and can undertake a lot of lifting operations.
What are the precautions for hydraulic storage tank lifting equipment?
What should I do if the platform of the hydraulic storage tank lifting equipment lift cannot be lowered?
What is the working process of hydraulic storage tank lifting equipment?
1) If the emptying phenomenon occurs during use, you can first loosen the oil drain screw on the pump body, hit the vertical head of the pump body down a few times, and then tighten the oil drain screw, you can continue to use the hydraulic storage tank lifting equipment.
2) When using, do not add partial load or overload, so as to avoid the danger of hydraulic storage tank lifting equipment damage. When there is a load, do not remove the quick connector to avoid accidents and damage to the parts.
When using hydraulic storage tank lifting equipment lift, sometimes the lifting platform cannot be lowered. The solution to the hydraulic storage tank lifting equipment lift not being lowered depends on the situation:
1. The drop valve fails,
Troubleshooting method: In the case of pressing the down button, check whether the down valve has electricity. If there is no electricity, try to eliminate it; if there is electricity, then eliminate the failure of the down valve itself and replace the drop valve.
2. The deceleration control valve is out of balance
Remedy: Adjust the descending speed control valve, if the adjustment is invalid, you need to replace the new valve.
When the hydraulic storage tank lifting equipment is stretched, the front and rear oil nozzles are opened, and oil is supplied from the rear oil nozzle to the tensioning working oil chamber, and the cylinder body of the tensioning cylinder moves backward. Since the cylinder cable is anchored on the tool anchor at the top of the jack, the hydraulic storage tank lifting equipment stretches the steel cable through the tool. When the wire rope is stretched to the required length, close the rear oil nipple, and feed oil from the front oil nipple into the top pressure cylinder, so that the top pressure cylinder piston moves forward to support the anchor plug, and the anchor plug is pressed into the anchor ring. Thus, anchoring the cable. Open the rear oil nozzle and continue to feed oil from the front oil nozzle. At this time, the tension cylinder moves forward and the oil in the cylinder returns. Finally, open the front oil nozzle to make the oil in the top pressure cylinder return, and the top pressure piston returns to its original position due to the action of the return spring.

The plasma and flame cutting machine is a portable multifunctional plasma welding, cutting, high energy flame heating equipment.
What are the precautions for the use of plasma and flame cutting machine?
Compared with similar products, what are the characteristics of plasma and flame cutting machine?
What are the advantages of plasma and flame cutting machine?
1. Points to be paid attention to in forging cutting
Due to the thicker oxide scale on the surface of the forging and the fact that the ignition point of the oxide scale is higher than the melting point, the plasma and flame cutting machine is prone to cutting interruption during cutting, resulting in reduced cutting quality and reduced work efficiency. For this reason, when the forging is cut, the oxide scale on the upper and lower surfaces of the cutting area should be removed before cutting to improve the cutting speed and cutting quality.
2. The main points of anti-deformation in rolling billet cooling bed tooth plate cutting
How to control the deformation of the workpiece during cutting is very important. For example, arranging the cutting route according to the routine will cause the workpiece to be deformed and out of tolerance. Even if it is reshaped, it is difficult to meet the size requirements, and the product will eventually be scrapped. Therefore, it is very important to arrange the gas cutting route of the plasma and flame cutting machine reasonably.
3. Points to be paid attention to in thick plate cutting
In thick steel plate cutting, the temperature decreases from the top surface down. At the beginning of cutting by plasma and flame cutting machine, the oxygen pressure is gradually increased, and finally reaches a uniformity in the thickness direction of the steel plate. This results in inconsistent combustion in the thickness direction of the steel plate at the starting position of cutting, and defects at the starting end of the workpiece cutting.
Compared with laser cutting: plasma and flame cutting machine is far less than laser cutting machine in terms of cutting speed accuracy and cutting material types, but it is better than laser cutting machine in cutting thickness and cutting cost.
Compared with high-pressure water jet cutting machine: the precision of high-pressure water jet cutting machine and the types of cutting materials are better than plasma and flame cutting machine, but plasma and flame cutting machine are larger than water jet cutting machine in cutting speed and cutting thickness, and the equipment The cost and cutting cost are relatively low.
The plasma and flame cutting machine can be used for drawing, programming, nesting, verification and CNC cutting of any shape parts. Improve the steel nesting rate, effectively save steel; improve the efficiency of programming, nesting and cutting, and effectively improve the cutting production efficiency.
Great products begin with the best engineering staff, and WINCOO ENGINEERING is ready to assist you with your technical requirements for plasma and flame cutting machine.
