General principles of tank hydraulic jacking system fault diagnosis.
Correct analysis of tank hydraulic jacking system failures is the prerequisite for troubleshooting. Most tank hydraulic jacking system failures do not occur suddenly. There are always signs before they occur. When the signs develop to a certain extent, the failure will occur.
The reasons for the failure of the tank hydraulic jacking system are various and there is no fixed pattern to be found. Statistics show that about 90% of tank hydraulic jacking system failures are caused by poor management. In order to diagnose failures quickly, accurately and conveniently, it is necessary to fully understand the characteristics and laws of tank hydraulic jacking system failures, which is the basis of fault diagnosis.
The following principles are worth following in the fault diagnosis of tank hydraulic jacking system:
① First, determine whether the working conditions and peripheral environment of the tank hydraulic jacking system are normal, and check whether the various conditions of the tank hydraulic jacking system meet the requirements of normal operation.
② Area judgment Determine the area related to the fault based on the tank hydraulic jacking system fault phenomenon and characteristics, and gradually reduce the scope of the fault.
③ Master the types of tank hydraulic jacking system faults and conduct a comprehensive analysis. According to the final phenomenon of the fault, gradually find out a variety of direct or indirect possible causes.
④ When verifying possible causes of failure, generally start from the most likely cause of failure or the most easily inspected place, which can reduce the workload of assembly and disassembly and increase the speed of diagnosis.
⑤ Establish a fault analysis table for the equipment operation tank hydraulic jacking system, which is a high-level summary of the use experience and helps to quickly make a judgment on the fault phenomenon.
The specific method of tank hydraulic jacking system fault diagnosis.
l The traditional method of finding hydraulic system faults daily is logical analysis and gradually approaching fault.
When the hydraulic system fails, there are many possible causes of the failure. Using the logic algebra method, list the possible failure causes, and then make logical judgments one by one according to the principle of easy first and then difficult, approach item by item, and finally find out the cause of the failure and the specific conditions that caused the failure.
l Fault diagnosis system based on parameter measurement
The idea of diagnosing faults by parameter measurement method is based on the fact that when any tank hydraulic jacking system is working normally, the system parameters are working near the design and set values. If these parameters deviate from the preset value during work, the system will malfunction or may malfunction.
That is, the essence of the failure of the tank hydraulic jacking system is the abnormal change of the system working parameters. During the measurement, there is no need to stop the machine or damage the hydraulic system. Almost any part of the system can be tested. Not only can the existing faults be diagnosed, but also online monitoring and potential faults can be predicted.
To summarize the fault diagnosis of tank hydraulic jacking system.
Apply the traditional logical analysis stepwise approximation method. It is necessary to analyze, judge and inspect all the above possible causes one by one, and finally find out the cause of the failure and the specific component that caused the failure. The diagnosis process of this method is cumbersome and requires a lot of assembly and disassembly, verification work, low efficiency, long construction period, and can only be qualitative analysis, the diagnosis is not accurate enough.
Application of fault diagnosis tank hydraulic jacking system based on parameter measurement. When piping the tank hydraulic jacking system, set a double ball valve and three ports at the outlet a of the pump, the front b of the reversing valve, and the inlet c of the cylinder, and the fault diagnosis detection circuit can be used to limit the system fault within a few seconds. In a certain area, the fault is diagnosed based on the measured parameter value.
Through the detection, the final cause of the failure is the serious internal leakage of the vane pump. After disassembling the pump, it was discovered that the vane pump stator caused abnormal wear due to poor lubrication, which caused internal leakage to increase and the tank hydraulic jacking system pressure did not increase. It was further discovered that the water in the water cooling tank hydraulic jacking system leaked into the oil, causing the oil to emulsify and lose its lubrication effect.
Welding machines refer to electrical appliances that provide power with certain characteristics for welding. Tank welding machines are widely used in various industrial fields, such as aerospace, shipbuilding, and automobiles due to their flexibility, simplicity, convenience, firmness, reliability, and strength even after welding. So how do we use thetank welding machine?

What are the classifications of tank welding machine?
There is no authoritative classification method for the classification of tank welding machine. The following classification is mainly based on the simple classification of the industry use on the market:
1. The tank welding machines mainly used by industrial and mining enterprises are: AC arc welding machine, DC electric welding machine, argon arc welding machine, carbon dioxide shielded welding machine, butt welding machine, spot welding machine, submerged arc welding machine, high frequency welding machine , Flash butt welding machine, pressure welding machine, butt welding machine, laser welding machine, AC welding machine and DC welding machine
2. There are two types of DC tank welding machine: one is to install rectifier components on the basis of AC motor, and the other is DC generator. DC welding machines mainly weld non-ferrous metals and pig iron. The AC welder mainly welds steel plates.
3. Argon arc welding machine, carbon dioxide protection welding machine, high frequency welding machine, flash butt welding machine. The argon arc welding machine and carbon dioxide shielded welding machine can mainly weld thin plates and non-ferrous gold layers below 2mm. The flash butt welding machine mainly connects copper and aluminum joints and other objects, and the high-frequency welding machine mainly welds steel pipes in the pipe factory.
4. Submerged arc welding mainly welds thick steel structure materials such as steel structural parts, bridge H steel, and I-beam beams.
5. Gas shielded welding: argon arc welding, carbon dioxide shielded welding, will not be oxidized when welding under the protection of gas, melting welding is firm, non-ferrous metals, thin materials can be welded.
6. Laser welding machine: can weld the leads inside the transistor.
7. Butt welding machine: the iron ropes and other objects on the anchors of the cable chain factory are mainly welded. It can be docked with Yuangang etc.
8. Multifunctional tank welding machine.
9. Spot welding machine.
10. Butt welding machine.
11. Bolt welding machine.
12. Carbon dioxide and ammonia gas welding machine.
The main features of tank welding machine.
l Reasonable design and free adjustment. Tank welding machines with different discharge frequencies can be selected according to different metal materials to achieve the best repair effect.
l The heat affected area is small. There is no heat input during the instant of cladding, so there is no deformation, undercut and residual stress. No partial annealing will occur, and no need to re-heat treatment after repair.
l The impact of tank welding machine is extremely small. The welding machine overcomes the impact of ordinary argon arc welding on the periphery of the work piece in the welding repair process. It is also possible to repair the work surface with no allowance.
l High repair accuracy. The surfacing thickness ranges from a few microns to a few millimeters, and only needs to be polished and polished.
l High welding strength. Due to the full penetration of the material on the surface of the work piece, a strong bonding force is produced.
l Adopt ring precision control.
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
