Hydraulic Pump Maintenance and Repair

Hydraulic pumps are the most important parts of hydraulic machinery. Has the function of providing hydraulic oil to control and operate equipment such as cylinders, hydraulic motors and other parts in the excavator. Due to long-term use, the hydraulic pump can cause problems and damage, so it needs to be checked and maintained promptly. So how to maintain and repair hydraulic pumps with Truong Linh Parts learn through the article below.

1. Common failures of hydraulic pumps

Hydraulic pumps can fail or malfunction for many different reasons. Below are some common causes of hydraulic pump failure:

Wear and tear: Over time, the internal parts of a hydraulic pump, such as pistons, valves, and other components, can undergo wear and tear. This can lead to reduced pump performance and eventual failure.
Impurities and dirt: If hydraulic oil contains impurities or dirt, they can cause damage to the hydraulic pump. Impurities can damage valves and other components, causing loss of pressure and flow control.
Pressure too high or too low: Operating the hydraulic pump at a pressure that is too high or too low compared to the original design can cause damage to the pump. Pressure that is too high can rupture the pump's internal components, while pressure that is too low can cause problems in generating the force to push the hydraulic oil.

Improper use: Improper use of a hydraulic pump, such as operating it at high temperatures or high pressures that it is not designed to withstand, can cause damage.
Problems in the hydraulic oil system: If your hydraulic oil system has problems such as the ability to deliver hydraulic oil quickly enough to the pump, not delivering enough pressure to the pump, or has an oil leak, the hydraulic pump may be affected and encounter problems.
Natural lifespan: Finally, hydraulic pumps have a natural lifespan and will experience breakdown due to wear and aging after long periods of use.
Hydraulic oil pump leaks: If the oil pump leaks, the pressure drops or there is no pressure. In addition to the strict assembly of pump parts, the main cause of pump leakage is the seal. To ensure the quality of the pump, it is also necessary to choose the quality of seals, joints and seals.

To prevent hydraulic pump failure, periodically maintain and service your hydraulic system, check the hydraulic oil, use clean oil and an effective filtration system, and follow your manufacturer's instructions. production and instructions for use.

2. Ways to maintain and repair hydraulic pumps

Hydraulic pump maintenance and repair is an important process to ensure the performance and longevity of the hydraulic system on excavators or other equipment. Below are some basic instructions on how to maintain and repair hydraulic pumps:

Periodic maintenance:

Change hydraulic oil: Make sure the hydraulic oil is always in good condition and at the right level. Change the oil periodically according to the manufacturer's instructions or the machine's user manual. Use high quality hydraulic oil to avoid damage to the pump and accessories.
Check pressure: Check the pump's operating pressure and consider the output pressure. If necessary, adjust the pressure to ensure stable operation.
Check control valves: Check pressure control valves to ensure they are operating properly. If you find any signs of leakage or damage, replace or repair immediately.
Clean the suction filter: A suction filter is located in the hydraulic pump tank. The suction filter is an important part of the hydraulic pump and keeps oil debris out of the pump. Because of its important role, clean it regularly.
