Each hydraulic pump makes some noise. If everything is normal with the pump, this noise remains more or less the same. However, if something goes wrong with the pump or its connected system components, you may start to hear sounds you have never heard before. For example, the pump may suddenly run noisier than usual. It may howl, complain, click or tap. Why does the pump sometimes make abnormal sounds?Zhongyou Heavy IndustryThree major reasons for the abnormal noise of the hydraulic pump.
1. fluid flow problems:
The fluid flowing through the system needs to move at a smooth and uniform speed. The pump must deliver fluid at a specific flow rate to work properly.
If for some reason the fluid is prevented from achieving and maintaining its optimal flow rate, your pump may start to make abnormal noises. For example, you might hear a squeal from a pump. This may be a constant or intermittent sound.
If your pump keeps buzzing, it may be a cavitation problem. Here, the pump cannot deliver the fluid at the correct volume or rate. There is not enough fluid through the pump suction line.
Cavitation is usually caused by plugging. For example, your pipes, filters, filters, or vents may be clogged or dirty to prevent fluid from flowing at the maximum rate. Alternatively, the fluid may be too viscous to run smoothly.
In some cases, this indicates that the pump's motor is set incorrectly. As a result, the pump itself works at the wrong speed to produce the correct flow.
If you hear intermittent complaints, there may be air in your liquid. Sometimes, a leak in your oil suction pipe or seal can cause air to enter and enter the fluid. Air creates bubbles in the fluid, and the bubbles effectively pop out as they move. If you have ventilation problems, you may also hear a rattling sound, which sounds like stones are hitting each other.
2. problem with faulty parts:
If there is a problem with one of the parts or connections of the hydraulic pump, noise may be generated. Pressure control devices, bearings, valves, seals or couplings that fail or malfunction may make sounds you have never heard before.
For example, if the safety valve stops working normally and opens permanently or frequently, the valve may hissing. The glued valve may make a loud noise when it opens and closes because it cannot run smoothly.
In some cases, if there is a problem with the connecting pipe, vibration may be heard when the pump is working. A loose seal or joint may cause the pipe to move. It then transmits the vibrations to the pump itself.
3. hydraulic pump fault:
Although some noise problems are easy to solve, there are some signs that your hydraulic pump is close to its service life. Sometimes, this is caused by natural wear, use and age. However, in some cases, if you don't solve the problem quickly, small problems can cause more extensive damage.
For example, if you have a cavitation problem for a period of time, your system may not get the lubrication it needs; it may often overheat. Even if you solve the cavitation problem, your pump may be damaged and require extensive repair, reconstruction or replacement.
Therefore, although an increase in new sounds or operating noise does not necessarily mean that you have a serious pump problem, you should investigate any abnormal noise. Usually, this is an indication that something is not right.
