When an Oil Pump Quits What Happens?

In the hydraulic system of construction machinery, the oil pump is regarded as the heart, providing hydraulic energy for the whole system. However, once the oil pump stops working, it will have a significant impact on the mechanical system. This article will explore in detail when an oil pump quits what happens.

 

Loss of pressure in the hydraulic system

When a hydraulic diesel oil pump stops working, the hydraulic system will lose its main power source, resulting in a rapid drop in system pressure. This can result in the hydraulic actuators not working properly, preventing the mechanical equipment from completing the required work tasks.

 

Hydraulic actuator failure

Due to a loss of pressure in the hydraulic system, the hydraulic actuators will not be able to generate enough force to perform mechanical movements. This can result in a loader's bucket not being able to lift, an excavator's bucket not being able to dig, or other hydraulic equipment not functioning properly.

 

Damage to System Components

A pump that stops working can cause hydraulic fluid to stagnate in the system, leaving some components within the system potentially subject to excessive pressure or excessive wear. This can lead to worn seals, leaks, and even damage to other diesel engine parts in the system.

 

Heat buildup

Hydraulic oil pumps also usually have a cooling system that is used to prevent the hydraulic fluid from overheating. When the pump stops working, it loses the support of the cooling system, which may lead to an increase in the temperature of the hydraulic fluid. Overheated hydraulic fluid may cause system malfunctions and affect the performance and life of the hydraulic fluid.

 

Changes in system noise

During normal operation, the operation of the hydraulic oil pump generates some noise, but when the pump stops working, the flow of hydraulic oil in the system stops and the noise level decreases. However, some other components in the system such as the starter motor may produce abnormal noise due to loss of oil lubrication.

 

Emergency Brake System Failure

Some construction machinery uses a hydraulic system as the power source for the emergency brake. When the oil pump stops working, the emergency brake system may fail, increasing the risk of the machinery and equipment in an emergency.

 

Increased system maintenance costs

An oil pump that stops working may mean that other components within the system are also affected and need to be repaired or replaced. This will increase maintenance costs and may result in prolonged downtime of the machinery and equipment, affecting the progress of the project.

 

The role of the hydraulic oil pump in construction machinery cannot be ignored, and once it stops working, it will have a serious impact on the entire hydraulic system. This will not only lead to mechanical equipment can not work normally, but also may cause other system failures. Therefore, regular maintenance and inspection of the hydraulic oil pump is a key step to ensure the normal operation of mechanical equipment. Timely detection and resolution of oil pump problems can help reduce system maintenance costs and ensure the long-term stable operation of construction machinery.
