Generally, after a long-term mechanical use of the vane pump, there will be more or less a long-term tracking process. In the follow-up process, there will be many problems in use, such as: insufficient pressure and other problems, then there will be insufficient pressure. In this case, can you still continue to use the vane pump? Let us briefly talk about the importance of this problem. I believe that these problems should be helpful to you. The following is our guide. The technicians of Otus told everyone that the reason analysis and treatment method of insufficient pressure of the oil research vane pump are as follows:
1. Loud noise
There are two reasons for the loud noise, the oil in the tank is not enough or the pump core is worn. When this problem occurs, you should first check whether the fuel tank is sufficient, and then check the pump core to see where the problem is.
2. The system oil temperature is too high
The reason for the high oil temperature of the system should be that the pipeline of the system is too small, the pressure is too high, the hydraulic oil cannot be discharged in time, and the cooling system does not meet the requirements, which leads to the phenomenon of oil trapping in the vane pump.
3. The system is depressurized.
System pressure drop means that the oil research vane pump can reach the predetermined pressure when working, which will cause the pressure to gradually drop during operation, making the system unable to work normally. When this phenomenon occurs, we should first check whether the master control valve is leaking or the oil temperature is too high, and whether the upper and lower oil distribution plates are worn.
4. No pressure
It means that the oil research vane pump has no pressure in the system during operation. First, check whether the vane pump has hydraulic oil discharged, secondly check whether the working direction of the oil pump is correct, and then check whether the coupling between the motor and the vane pump is connected. OK, the last is to check whether the total pressure valve fails.
5. Pressure swing
This situation means that the pressure of the oil research vane pump is unstable during operation. If there is no increase in noise accompanied by this phenomenon, it is generally possible to directly check the total pressure valve to see if it is worn. If there is a problem with the pump core, it will be accompanied by the phenomenon of increased noise.
The single-plate pump can change the meteor, that is, the variable pump? The double-plate pump cannot change the flow, that is, the quantitative pump. The variable vane pump is mostly a single-acting vane pump, and the purpose of variable is achieved by changing the eccentric distance.
At the same time, we can see that the society is progressing, whether it is metering diaphragm pump, diaphragm pump or vane pump and other equipment are progressing. Vane pumps have developed rapidly after their introduction, and now there are single-acting vane pumps and double-acting vane pumps. Now the use of these two devices is becoming more and more mature, and it is believed that many people have certain needs for them. I believe that there must be a lot of debate on the difference between single-acting vane pumps and double-acting vane pumps.
