Analyze the Causes of Noise in High Pressure Pump Gears […]
Analyze the Causes of Noise in High Pressure Pump Gears and Solutions: The high pressure pump is a high-pressure power supply equipment for high-pressure rotary jet grout. It has been widely used in the construction of construction, roads, pipelines and other equipment. However, when using high pressure pumps, high pressure pump gears often exhibit noise, then high pressure pump gears. What is the cause of the noise and how should it be handled?
The noise of the high pressure pump gear has the following possible aspects: (1) the impact of the rotary vane on the cylinder, the residual volume of the gear high pressure pump and the sound of the pressure oil in the exhaust dead space; (2) the exhaust valve-to-valve The impact of the seat and the support member; (3) the echo and bubble cracking sound in the box; (4) bearing noise; (5) the noise caused by many gas and oil impacting the oil baffle; (6) others. Such as noise caused by the transmission, fan noise of the air-cooled gear high pressure pump. (7) Motor noise, which is a crucial factor.
Detailed operation method for handling high pressure pump noise problems:
1. For the self-priming high pressure pump, it should be placed in the well-ventilated local operation as much as possible to facilitate rapid heat dissipation and lower the motor temperature. Otherwise, long-term operation, it is easy to burn the motor. For example, when a farmer uses a self-priming high pressure pump, the motor is overheated and the coil is burned out because the plastic film covering the motor is not removed. Before starting, be sure to check the water storage capacity in the high pressure pump. Otherwise, it will not only affect the self-priming performance, but also easily burn the shaft seal parts. Under normal conditions, the water should be discharged within 3 to 5 minutes after the high pressure pump is started, otherwise it should be stopped immediately.
2. High pressure pump repair When the high-pressure pump presents a problem, it is forbidden to start disassembling it yourself. When I opened it myself, I did not know where the problem was and formed a blind dismantling. Second, there was no special tool and it often damaged the original parts. The best way to do this is to have an experienced, planned repair point to repair and replace overage parts and certain consumables in a timely manner. Under normal conditions, the high pressure pump should be repaired once every six months to eliminate the disease.
