The gas-electric vertical welding used by tank welding machine is a fully automatic control ascending system with a special flux-cored wire, and CO2 gas shielding for vertical butt welding to weld vertical or near-vertical welded joints.
What is tank welding machine?
How many kinds of tank welding machine?
What is the preheating method of tank welding machine?
Large storage tank automatic welding machine, large storage tank is used to store oil, natural gas, and other energy. This kind of tank because the body is too big, cannot be formed at a time, are made of steel plate, splicing. So the welding machine is needed in the splicing process. Manual welding is the simplest and most direct method, but because of its high cost and low welding speed. So automation equipment has been widely used. Large tank automatic welding equipment, we are also known as tank automatic welding machine, the following for you to introduce several commonly used automatic welding machine: horizontal welding machine, vertical welding machine and Angle flat welding machine.
The so-called horizontal welding machine is a kind of welding machine that welds steel plates horizontally in the storage tank prefabrication.
The so-called vertical welding machine is a kind of welding machine that welds steel plates vertically in the storage tank prefabrication.
The so-called Angle flat welder is a welder that welds the bottom plate and the corners in the storage tank prefabrication.
After the arc of the welding rod of the tank welding machine is started, the arc is slightly elongated. In the state that the arc is not extinguished, the end of the welding rod is melted and a few droplets fall down. At this time, the welding rod has reached the normal burning state. At the same time, the use of the tank welding machine The heat generated by the arc heats the weld start. If it is found that the surface of the spot-fixed weld at the start of the weld begins to show signs of melting, the electrode will press the arc towards the lower edge of the spot-fixed weld, and then weld upward; The electrode reduces the welding speed slightly and turns the arc upwards. At this time, the electrode pauses for a while, and the rear edge of the weld joint is broken down in advance, and a molten pool and a molten hole are formed, and the formed molten hole must ensure that the blunt edge of both sides is 1.0~1.5 mm. At this time, the seam has been connected, and the electrode can be welded normally.

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?
What are the structural parts of hydraulic storage tank lifting equipment?
What should be paid attention to before using 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!
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.
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.
WINCOO ENGINEERING CO., LTD has committed to the research and product of hydraulic storage tank lifting equipment for several years, it will provide the best quality products.
Simple chain type hydraulic jacking system 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 storage tanks (steel) and various storage tanks.
LYT-type simple chain type hydraulic jacking system includes the following models: LYT-120-2700, LYT-200-2700, and LYT-300-2700 etc. (those with special stroke need to be customized).
What is the operation process of the simple chain type hydraulic jacking system?
What is the working principle of the simple chain type hydraulic jacking system?
What are the advantages of simple chain type hydraulic jacking system?
LYT-type simple chain type hydraulic jacking system is used to firstly lift the tank roof and the top (first layer) siding of the tank. It's required to group weld tank siding when the lifting height of siding exceeds the second siding (the second layer from the top) by 30-50mm, and group weld the third layer (the third layer from the top to the bottom) of the tank after lifting again, lift successively, group weld the siding of the tank layer by layer, until the last layer of siding.
LYT-type simple chain type hydraulic jacking system is used for lifting. When oil enters the hydraulic jack, the movable pulley is pushed upward by pressing the piston, thus driving the load-bearing chain to lift the expansion ring. In this way, the whole tank (including tank roof) is lifted up, until it reaches the pre-set height (there is a voidance of the next layer of plate). The siding in this layer is surrounded for butt welding. After the positioning block is welded, hydraulic hoist returns and the lift tank falls back to the newly-surrounded siding. After welding of circular seam and vertical seam, the door-type card for fixing expansion ring is cut off and the expansion ring is released. In this way, the hoist returns and expansion ring falls to the Model of hydraulic pump station Tank volume Rated pressure Rated flow Power Control voltage of solenoid valve Motor drive rate YB-7.2 220L (700*550*580) 25Mpa 7.2L/min Three-phase Four-wire (380V) 220V 5.5KW YB-14.5 340L (750*650*650) 25Mpa 14.5L/min 220V 7.5KW Mode of LYT-type hoist Rated lifting capacity (KN) Hydraulic area (mm) Rated oil pressure (MPa) Piston stroke (mm) Chain stroke (mm) Cylinder safety equipment Reinforcement measures LYT-120-2700 120 11304 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods LYT-200-2700 200 18859.6 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods LYT-300-2700 300 25434 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods bottom of tank siding. Then, the next circular plate is expanded and transfer rib plate, such as door-type card, is welded for lifting, and so forth. The group welded tank is lift, until group weld of the last layer of siding, so that the whole storage tank is installed with this inverted method.

Tank hydraulic jacking system is mainly a closed or meshed hoistway enclosed by buildings or light steel structures and hydraulically driven cylinders to lift the platform. So what are the advantages and disadvantages of the use of tank hydraulic jacking system?
Here is the content list:
l What are the components of the tank hydraulic jacking system?
l What are the advantages and disadvantages of tank hydraulic jacking system?
l How to deal with the shortcomings of tank hydraulic jacking system?
A complete tank hydraulic jacking system consists of five parts, namely power components, executive components, control components, auxiliary components (accessories) and hydraulic oil.
The function of the power element is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, which refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The structure of hydraulic pumps generally includes gear pumps, vane pumps, plunger pumps and screw pumps.
The function of the executive components (such as hydraulic cylinders and hydraulic motors) is to convert the pressure energy of the liquid into mechanical energy, and drive the load for linear reciprocating motion or rotary motion.
Auxiliary components include fuel tanks, oil filters, coolers, heaters, accumulators, oil pipes and pipe joints, sealing rings, quick-change joints, high-pressure ball valves, hose assemblies, pressure measuring joints, pressure gauges, oil level gauges, oil Thermometer etc.
The tank hydraulic jacking system consists of hydraulic pump station, oil cylinder, steel wire and stroke, which is easy to install and operate. The tank hydraulic jacking system uses PLC central control for lifting. Each power unit is equipped with an auxiliary balance device to ensure the accuracy of simultaneous lifting. In addition, the hydraulic lifting pump station has two operating modes: auxiliary manual control and control. The cylinder can be adjusted to lift individually, or it can be combined with other lifting units into a group, or it can be integrated with multiple lifts to achieve higher accuracy and better welding results!
On the other hand, all cylinders of the tank hydraulic jacking system are equipped with safety valves. It can be automatically locked, even in the event of a power failure, a rupture of the high-pressure hose, or a rupture, it can prevent the cylinder/fuel tank from falling. The number of tank hydraulic jacking system can be adjusted according to the tank size and weight high efficiency, it only takes 15 minutes for each rise or fall. It can be used in conjunction with our company's slot welding machine, which can greatly reduce labor costs and reduce construction time.
l Advantages of tank hydraulic jacking system:
1. Small size and light weight
2. Large rigidity, high precision and fast response
3. Large driving force, suitable for heavy load direct drive
4. Wide speed range and various speed control methods
5. Self-lubricating, self-cooling and long life
6. Easy to realize security protection
l Disadvantages of tank hydraulic jacking system:
1. Poor anti-contamination ability of working fluid
2. Sensitive to temperature changes
3. There is a hidden danger of leakage
4. Difficult to manufacture and high cost
5. It is not suitable for long-distance transmission and requires hydraulic energy
The tank hydraulic jacking system is generally flushed before it is officially put into operation. The purpose of flushing is to remove contaminants, metal chips, fiber compounds, iron cores, etc. remaining in the system. During the first two hours of work, even if the tank hydraulic jacking system is not completely damaged, It will also cause a series of failures. Therefore, the oil circuit of the tank hydraulic jacking system should be cleaned according to the following steps:
l 1) Clean the oil tank with an easy-to-dry cleaning solvent, and then use filtered air to remove solvent residues.
l 2) Clean all pipelines of the tank hydraulic jacking system. In some cases, the pipelines and joints need to be immersed.
l 3) Install oil filter in the pipeline to protect the oil supply pipeline and pressure pipeline of the valve.
l 4) Install a flushing plate on the current collector to replace precision valves, such as electro-hydraulic servo valves.
l 5) Check whether all pipelines are of appropriate size and connected correctly.
If it is found that the oil filter is clogged, change the oil filter immediately. The flushing cycle is determined by the structure of the tank hydraulic jacking system and the degree of system pollution. If the sample of the filter medium has no or few foreign pollutants, install a new oil filter and unload it. Flush the plate and install the valve to work! Planned maintenance: Establish a regular system maintenance system, and suggestions for better maintenance of the tank hydraulic jacking system are as follows:
l 1) Check and replace the oil at most 500 hours or three months.
l 2) Flush the imported oil filter of the oil pump regularly.
l 3) Check whether the hydraulic oil is contaminated by acidification or other pollutants. The smell of the hydraulic oil can roughly identify whether it has deteriorated.
l 4) Repair leaks in the tank hydraulic jacking system.
l 5) Ensure that no foreign particles enter the fuel tank from the vent cap of the fuel tank, the plug seat of the oil filter, the sealing gasket of the oil return line and other openings of the fuel tank.
