Why does Komatsu PC40-8 hydraulic pump accessories make abnormal noise

The function of the hydraulic cylinder is to convert hydraulic energy into mechanical energy. Komatsu PC40-8 hydraulic pump accessories hydraulic cylinder input is fluid flow and pressure, output is linear motion speed and force. The piston of the hydraulic cylinder can complete linear reciprocating motion, and the output linear displacement is limited.

The hydraulic cylinder is an energy conversion device Komatsu PC360-7 hydraulic pump accessory that converts hydraulic energy into reciprocating linear motion mechanical energy. The hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. The buffer device and exhaust device depend on the specific application, other devices are essential. The hydraulic cylinder will make abnormal noises during use, so what causes this? Here is a brief introduction for everyone.　　

1. Air intrusion into the hydraulic system is the main cause of noise.　　

2. The overflow valve is unstable. For example, the valve core is stuck or stuck in the valve hole due to the improper fit of the spool valve and the valve hole, or the contact between the cone valve and the valve seat is stuck by dirt, the orifice is blocked, the spring is skewed or invalid, etc. Failure to move, causing system pressure fluctuations and noise.　　

3. Improper adjustment of the reversing valve causes the spool of the reversing valve to move too fast, and the Komatsu PC200-2 hydraulic pump accessories cause reversing shocks, resulting in noise and vibration.　　

4. Mechanical vibration, such as the slender tubing of the hydraulic oil cylinder, many elbows without being fixed, it is easy to cause the tubing to shake when the oil flows through, especially when the flow rate is high; Poor alignment during installation or loose couplings can cause vibration and noise.
