Common problems when using tank hydraulic jacking system.

Reasons for leakage of tank hydraulic jacking system.

(1) Caused by defects in design and manufacturing

(2) Impact and vibration cause loose pipe joints

(3) Mutual wear of dynamic seals and matching parts (especially hydraulic cylinders)

(4) The oil temperature is too high and the rubber seal is incompatible with the hydraulic oil and deteriorated.

Combining the above problems, talk about the measures to control the leakage of tank hydraulic jacking system.

l Solution 1: Design and manufacturing defect solutions

The selection of external components of tank hydraulic jacking system often plays a decisive role in the leakage of hydraulic system. This determines that in the improvement of tank hydraulic jacking system, our technicians should carefully choose the cylinders, pumps, valves, seals, hydraulic accessories, etc. based on the principle of choosing the best among the best and choosing the cheap.

①　Reasonably design the mounting surface and sealing surface of the tank hydraulic jacking system. When the valve block or pipeline is fixed on the mounting surface, in order to obtain a satisfactory initial seal and prevent the seal from being pushed out of the groove and being worn.

②　The installation surface of the tank hydraulic jacking system should be straight and the sealing surface should be finished. The surface roughness should reach 0.8μm and the flatness should reach 0.01/100mm. The surface must not have radial scratches, and the pre-tightening force of the connecting screw must be large enough to prevent surface separation.

③　During the manufacturing and transportation of tank hydraulic jacking system, it is necessary to prevent the key surface from bumping and scratching. At the same time, the assembly and debugging process must be strictly monitored to ensure the quality of assembly.

④　Do not be taken lightly about the leakage of some tank hydraulic jacking system, and must be eliminated.

l Option 2: Reduce shock and vibration

In order to reduce the leakage of tank hydraulic jacking system caused by the loosening of pipe joints subjected to shock and vibration, the following measures can be taken:

①　Use shock-absorbing brackets to fix all pipes to absorb shock and vibration;

②　Use low-impact valve or accumulator to reduce the impact;

③　Properly arrange pressure control valves to protect all components of the tank hydraulic jacking system;

④　Minimize the number of pipe joints used, and try to use welding to connect pipe joints;

⑤　Use straight threaded joints, tee joints and elbows instead of tapered pipe threaded joints;

⑥　Try to replace each piping with oil return block;

⑦　For the highest pressure used by the tank hydraulic jacking system, specify the bolt torque and plug torque during installation to prevent the joint surface and seal from being eaten away;

⑧　Install the pipe joints of the tank hydraulic jacking system correctly.

l Option 3: Reduce the wear of dynamic seals

Most of the dynamic seals have been precisely designed. If the dynamic seals are qualified, installed correctly, and used reasonably, they can guarantee a long-term relatively leak-free work. From the perspective of tank hydraulic jacking system design, designers can take the following measures to extend the life of dynamic seals:

①　Eliminate the side load on the piston rod and drive shaft seal;

②　Use dust ring, protective cover and rubber sleeve to protect the piston rod to prevent abrasives, dust and other impurities from entering;

③　Design and select a suitable filter device and a fuel tank that is easy to clean to prevent dust from accumulating in the oil;

④　Keep the speed of the piston rod and shaft as low as possible.

Matters needing attention when using tank hydraulic jacking system.

First of all, the requirements for static seals,tank hydraulic jacking system static seals prevent oil leakage between rigid fixed surfaces. Reasonably design the size and tolerance of the seal groove, so that the installed seal will be deformed to a certain extrusion so as to fill the microscopic depression of the mating surface and increase the internal stress of the seal to be higher than the pressure to be sealed.

It should be noted that when the rigidity of the part or the pre-tightening force of the bolt is not large enough, the mating surface will separate under the action of the oil pressure, causing a gap or increasing the gap that may exist from the beginning because the sealing surface is not flat enough. As the mating surface moves, the static seal becomes a dynamic seal. Rough mating surfaces will wear the seal, and the fluctuating gap will eat away at the edge of the seal.

In addition, control the oil temperature to prevent deterioration of the seal. Premature deterioration of the seal may be caused by many factors. An important factor is the high oil temperature. Each time the temperature rises by 10°C, the seal life will be halved. Therefore, a reasonable design of an efficient tank hydraulic jacking system or a forced cooling device should be provided to keep the optimal oil temperature below 65°C.

Among them, engineering machinery of tank hydraulic jacking system must not exceed 80°C, and hydraulic oil and seal types and materials should be selected according to the operating instructions or relevant manuals to solve compatibility problems and extend the service life of seals.

What are the advantages of orbital welding machine?

The application range of the orbital welding machine is greatly increased, the structure is simple, the cost is low, the purchase cost of the user can be reduced, the installation operation is convenient, the auxiliary operation time is short, and the work efficiency is high. The support flexible rail includes two parallel rails, and each rail includes a strip substrate.

What are the technical requirements when using the orbital welding machine?

Orbital welding machine shall not be used if the rail has the following conditions:

1. The rail is judged to have internal damage or serious surface injury.

2. The depth of the pit after the top surface of the rail head is damaged and polished:

Weld repair on the line exceeds 8 mm;

Solder repairs over 10 mm outside the line.

3. For scratches, spalling, falling blocks and welding joint wear, low collapse, etc. on the top surface of the rail head, the allowable length of welding repair shall meet the following requirements:

For rail joints (including welded joints) wear and low collapse, the allowable one-time welding repair length is 300 mm, and if the damaged length exceeds 300 mm, it should be divided into two sections for welding repair.

For defects and damages such as scratches, spalling and falling blocks on the top surface of the rail head, the length of one welding repair is allowed to be 200 mm. If the length exceeds 200 mm, it should be divided into two sections for welding repair.

When the rail joints are worn, slumped, scratched and peeled off at the same time, the scratches and peeled off blocks should be dealt with first.

What are the fields of application of orbital welding machines?

At present, the development of railways is mainly in the direction of high-speed passenger cars, subway passenger cars, light rail cars, high-speed heavy-duty trucks, etc. In order to achieve these needs, it is necessary to reduce the weight of trains. A common practice now is to use aluminum alloy materials in the manufacturing process of passenger cars. Because aluminum alloy materials have the characteristics of light weight, corrosion resistance, smooth appearance, complex curved surfaces, and high specific strength, they can effectively reduce the resistance and quality of passenger cars, and increase the overload. In order to effectively improve the processing efficiency of aluminum alloy materials, it is necessary to change the traditional processing method and use the welding technology of the orbital welding machine for processing and manufacturing.

Research background of tank welding machine.

Metal pipe welding is an important part of aeroengine. Fuel, lubricating oil, air, oxygen and other working media in each system rely on metal pipes for transmission. Aviation engine pipeline parts have many types, large quantity, and high accuracy grade. Therefore, the requirements for manufacturing precision and quality are very high, and the requirements for manufacturing methods are getting higher and higher.

The main manufacturing method of metal conduit is tank welding machine welding. The welding of metal conduits of aero-engines mostly adopts manual argon arc welding, flame brazing, induction brazing, etc. The above-mentioned welding method is easy to operate, simple in equipment, low in cost, and low in requirement for a single welded pipe. Pipes, so it is widely used for pipe welding.

However, these welding methods are manual operations, which require very high skills for tank welders. Usually the weld formation is not ideal, and defects such as weld deviation, dents, weld leakage and incomplete welding will occur.

The application prospect of tank welding machine in the future.

In recent years, with the large-scale application of metal conduits, the welding quality requirements of metal conduits have become higher and higher, and the welding of automatic welding machines has become an ideal conduit welding method.

In the 1990s, there was an automatic girth welder for welding metal pipes. The diameter of the welded pipe could cover all the metal pipes on aero engines.Therefore, in recent years, automatic welding machines have been applied to the welding of metal conduits of aero-engines and have achieved success.

What are the application environments of tank welding machine?

In the operation of picking and exchanging electronic components, a tank welding machine welding process is required. Often in order to locate the problem of the circuit function, it is necessary to remove the components from the printed circuit board and perform the necessary measurements.

Generally, the reliable and successful operation of equipment related to space, defense, medical electronics, traffic control systems, communication systems, and supervision and control systems all rely on excellent tank welding machine welding.

1) Disassembly of extra components;

2) Inspection of components;

3) Exchange of defective components;

4) Check the circuit function.

The welding technology of the tank welding machine is an accompanying technology. With the development of the electronics industry, more useful packaging technologies and smaller components will certainly continue to appear, and tank welding machines will continue to be developed to meet the needs of the electronics industry and environmental issues. This is why for technology professors working in the electronics industry today, welding has become more and more professional!

Tank welding machines are actually transformers with lower external characteristics, which convert 220V and 380V alternating current into low-voltage direct current. Electric welding machines can generally be divided into two types according to the output power source. Therefore, tank welding machines can be divided into many types according to different characteristics.

Here is the content list:

l Tank welding machines are classified according to power characteristics.

l What types of tank welding machines does WINCOO have?

l What are the classifications of tank welding machines based on the market industry?

Tank welding machines are classified according to power characteristics

One type of tank welding machine is AC power and the other is DC power. A DC welding machine can be said to be a high-power rectifier. It is divided into positive and negative poles. When AC power is input, it is transformed by a transformer, and then rectified by the rectifier, and then outputs a power source with reduced external characteristics.

The output terminal will produce huge voltage changes when it is switched on and off the tank welding machines. When the two poles are short-circuited momentarily, the arc is ignited, and the generated arc is used to melt the electrode and welding material, and after cooling, the purpose of combining them is achieved. Welding transformers have their own characteristics. The external characteristic is the sharp drop in voltage after the electrode is ignited.
