Maintenance and maintenance of well submersible pumps

Water is ubiquitous in life, and water comes from wells. Today, Longmai Pump Industry will take you to see a great invention related to water! Today, let's take a look at the submersible pump for wells and its maintenance and maintenance process. (1) Regularly test and record the insulation resistance. If the resistance is lower than the specified value, the cause should be found and dealt with in time. (2) The mechanical seal in the well submersible pump, which plays a role in preventing sand and sealing, directly affects the safe operation of the electric water pump. Therefore, when the leakage exceeds the specified value, timely maintenance should be carried out. During maintenance, in addition to removing the seals to be replaced, the following should also be done

Reasons and solutions for high vacuum pump motor temperature

Vacuum pumps are used to evacuate air during unit startup and to remove uncondensed gases from the condenser during normal operation. The pump is equipped with a 160kW motor, with a speed of 590r/min, a rated current of 330A, a voltage of 380V, and B-class insulation. During normal operation, the current is 220～230A. Every summer, the motor temperature exceeds the limit, forcing the installation of a temporary cooling fan, but with little effect. Long-term high-temperature operation of the motor will cause insulation aging and shorten its service life. Yutong Pump Industry analyzes the reasons for the high temperature of the vacuum pump motor as follows. Reason analysis: (1) The motor has high power, large working current, and large heat generation. (2

What are the advantages of submersible pumps?

Submersible pumps are the leading water pump products of Hebei Yutong Pump Co., Ltd. The advantages of submersible pumps are summarized as follows: 1. Convenient installation and maintenance. Small sewage pumps can be directly connected to hoses for mobile and free installation. Large sewage pumps generally use pipeline installation and can be equipped with automatic coupling devices for automatic installation (allowing the water pump to be lifted out of the water without underwater work), making installation and maintenance quite convenient. 2. Long continuous running time. Because the pump and motor are coaxial in sewage pumps, the shaft is short, and the rotating parts are light, the load (radial) on the bearings is relatively small, and the service life is much longer than that of ordinary pumps. If high
