Piston type oil pumps are widely used in various industrial scenarios because of their high efficiency and long-term reliability. However, due to irregular maintenance or aging of the pump, the piston type oil pump may fail, causing loss of production, downtime and economic losses. The following is a detailed analysis of the common failure causes of piston type oil pumps and solutions.
1. Worn or damaged internal parts
One of the most common causes of piston type oil pump failure is worn or damaged internal parts, which can be caused by a variety of factors. In particular, when a new pump is used for a long time, attrition due to friction between internal components is inevitable. Besides, improper usage, such as using non-qualified materials, overloading or rough handling, will also cause internal damage, causing insufficient oil supply and leakage, resulting in failed operation of the pump.
In such cases, technicians need to carefully check the pump for any wear or damage. After the inspection, appropriate wear parts need to be replaced in a timely manner. In addition, to avoid excessive wear and tear on the pump, regular maintenance and usage should be taken into account.
2. Alignment failure
If the installation of the pump fails to meet the specified requirements, misalignment of the piston type oil pump will occur, resulting in noise and vibration, and failure of the pump. In general, if the holes between the inlet and outlet valve of the pump do not match, the performance of the pump will decrease significantly.
In this case, the technician needs to carefully inspect the alignment of each component and use appropriate tools to ensure that the pump is correctly aligned. If necessary, the components should be adjusted or replaced in order to properly align the pump.
3. Blocked inlet and outlet valve
In the normal operation of piston type oil pumps, the clogging of the inlet and outlet valves will occur, resulting in blocked oil circulation, inadequate oil supply, and eventually causing the failure of the pump. Such clogging is mainly caused by oil impurities, such as dust and metal chips.
Therefore, in order to avoid oil blockage, it is important to regularly filter the oil and check for oil impurities. In addition, the inlet filter should be cleaned or replaced regularly to ensure smooth oil flow.
In conclusion, piston type oil pump failure can be caused by a variety of factors, such as abrasion and misalignment of internal components, and blockage of inlet and outlet valves. It is important to note that regular maintenance and usage is essential in order to ensure long-term reliability and efficiency of the pump. By taking the appropriate steps, such as timely replacement of worn out parts and regularly checking for oil impurities, pump failure can be avoided.
