The noise of the pump may have the following reasons

Shenyang water pump to the water pump has made the analysis of several aspects of noise

1 rotary vane of a cylinder body collision, residual volume pump and exhaust pressure oil in the die gap voice;

2 exhaust valve piece of support for the seat and a crash;

3 the casing of the echoes and bubble burst;

4 bearing noise;

5 large amounts of gas, oil shock caused by noise such as oil baffle plate;

Six others. Such as transmission caused by the noise, air cooling water pump fan noise, etc.

7 motor noise, it is the crucial factor.

(1) in order to improve the efficiency and reliability, for the purpose of continuous improvement of old products, develop new products. Value the hydraulics, cavitation corrosion and wear of pump and mechanical design, especially the rotor dynamic design. CFD (computational fluid dynamics method can replace traditional model experiment and the design of the flow measurement as a pump, analysis and study of operating performance.

(2) promote plant pump energy saving technology and application of variable drive technology to reduce pollution emissions. Improper selection by redesigning the impeller, transform or pump operating conditions change, to adapt the pump to the new conditions. Reduce the leakage of light hydrocarbon products, to protect the environment.

(3) improve the design, improve the operation reliability and operation life of users generally require continuous running 50000 hours for requirements and design life of 20 years, foreign pump company from structure, material selection, processing, and study and improvement on the design of auxiliary system. Application of ceramic materials of high strength plastic material of sliding bearing, gear pump gear, shaft, worm and worm shaft of pump, etc.

(4) improve the level of monitoring measurement by ultrasonic condition monitoring, infrared spectrometer side, temperature monitoring, traffic monitoring, power monitoring method to detect the normal operation of the pump. The important pump group using on-line monitoring system analyse the reason of abnormal in a timely manner.
