Signs that the hydraulic pump needs to be repaired

 

1. internal and external leaks:

 

If you find that the performance of the hydraulic pump is degraded, then if there is no external leakage, it may be an internal leakage. Internal leakage may occur without the user seeing any signs, but it is serious in terms of the service life of the pump. The external leakage is obvious and obvious. It is usually relatively easy to use a new seal or valve to solve the leakage problem and repair it before the problem is serious and causes a failure.

 

2. abnormal sound:

 

The working principle of the hydraulic pump is to minimize the noise, so if you hear sounds such as knocking, loud popping or popping, it means that some equipment is working abnormally. These sounds are usually problems of air entrapment or cavitation, usually caused by insufficient pressure. This problem may cause a catastrophic failure of the hydraulic pump and should be resolved immediately. This problem can usually be resolved by finding the source of air entering the system and repairing it, and venting the system after the repair.

 

3. periodic seal failure:

 

If the gasket on your hydraulic pump fails regularly, there may be some reason why it needs to be repaired. One of the most common causes is a misaligned or bent rod. Depending on the degree of serious damage to the rod, the hydraulic repair shop may be able to repair existing parts and equipment at a lower cost and make the pump run normally in a relatively short time, thus saving the company time and money.

 

4. high working temperature:

 

Fluid viscosity is important to keep the hydraulic pump running smoothly and normally. The viscosity depends on factors such as temperature and pressure. If the temperature or pressure is not within the recommended guidelines, your pump will be subjected to unnecessary tension, which will eventually lead to damage and failure. As a basic guideline, a temperature of 180 degrees Fahrenheit or higher will have a negative impact on your equipment. If the cooling function of the system is not normal, it will usually reach this temperature. If this is the case with your hydraulic equipment, make sure to check that the fuel tank is free of obstacles, because the fuel tank can be used as a radiator to help dissipate heat in certain systems, and check the heat exchanger.

 

5. sluggish and slow performance:

 

If your hydraulic pump seems sluggish or slow and its performance drops significantly, it may be that your pump is broken. The slow running of the pump and the longer cycle time are obvious signals that you need to repair, otherwise your pump system will eventually fail. This inefficiency usually indicates insufficient fluid flow and should be inspected and repaired.

 

What happens 6. air enters the system?

 

The problems mentioned earlier in this article are some of the most common symptoms of air in hydraulic pumps and expansion systems. Problems include higher temperatures, cavitation, true spongy and unresponsive in use, and low liquid levels in the system.

 

How often is it 7. to replace the hydraulic oil in the hydraulic pump system?

 

Hydraulic oil is one of the most important parts of the hydraulic pump system, which is essential for smooth operation and prevention of unnecessary damage. Your hydraulic system needs to keep its fluid within a certain range of purity. The hydraulic oil in the system should be checked every 100 hours of use, and the entire hydraulic system should be cleaned, and new hydraulic oil should be added every 1000 hours or according to the recommendations of the hydraulic pump manufacturer.
