Hydraulic Pump Makes Noise, Gets Hot

Hydraulic pump - One of the important parts in the hydraulic system. Its role is to supply oil by pressurizing and pushing hydraulic oil through pipes and valves to perform mechanical work or control components in industrial and machinery applications. Long-term operation will cause the pump to malfunction and cause damage. So what is the cause of the noise and how to fix it? Let's find out with Truong Linh Parts in the article below.

1. Causes of hydraulic pump noise and heat

A noisy and hot hydraulic pump can be a sign of many different problems in the hydraulic system. Here are some common causes of this condition:

Insufficient or too much hydraulic oil: Hydraulic oil is an important part of the system. If the oil level is too low or too much, the pump may not operate effectively, leading to noise and high temperatures.

Clogged filter: Hydraulic systems often have a filter to remove any dirt or impurities in the hydraulic oil. If the filter is clogged, the oil does not circulate smoothly, causing pressure and heating of the pump.

The amount of oil remaining in the tank is too low: If there is too little oil in the tank, the temperature of the hydraulic oil will increase rapidly during machine operation. To ensure optimal machine operation, it is best to keep the oil level stable and always at least 1/3 of the total oil amount.

Bad Seal: If the pump seal is damaged or loose, oil can leak inside the pump and cause it to heat up.

Pressure too high: Hydraulic pressure that is too high can lead to increased temperature. If the pump operates at too high a pressure for a long time, it will get hot and may cause damage.

Inappropriate hydraulic oil: Using the wrong type or poor quality hydraulic oil can cause heat and noise in the pump.

Hydraulic oil contaminated with air: In some cases, leaks or scratches on the suction line can cause air to get inside the fluid. Air creates bubbles in the liquid. These bubbles will explode when you move.
