A mine-used large-flow high-pressure pump and its method

Abstract

The invention discloses a mine-used large-flow high-pressure pump and a method thereof. The pump includes a pump body and a base. 1. The crushing chamber is set up sequentially from top to bottom; the impeller is set in the pressurized water chamber; the cutting mechanism is set inside the crushing chamber; the working method of the pump completes the sewage discharge work of the pump through multiple steps. The large-flow high-pressure pump for mining of the present invention has a reasonable structure and a large flow rate. The setting of the crushing chamber in the pump can crush the impurities in the sewage twice, and the debris crushing effect is better, and large pieces of debris in the sewage can be avoided. Damage the impeller, protect the impeller from wear, and improve the service life of the pump; and all the sewage entering from the suction port of the pump base passes through the cavity between the winding casing and the motor casing to achieve full flow and flow The water cools the shell surface of all heat-generating parts of the motor, which greatly improves the service life of the pump.

Description

technical field [0001] The invention relates to a pump and a method, in particular to a mine-used high-flow high-pressure pump and a method. Background technique [0002] Mine pumps can be used for mine drainage. When in use, the whole pump is submerged in water to work. After the pump is turned on, the impeller rotates at high speed, and the liquid in it rotates with the blades. Under the action of centrifugal force, it flies away from the impeller and sprays out. The speed of the liquid in the diffusion chamber of the pump casing gradually slows down, the pressure gradually rises, and then flows out from the pump outlet drain pipe. At present, the mine pump motor used in the mine generates a lot of heat, which is easy to cause damage to the internal components of the motor housing and affects the normal use of the mine pump. In addition, during the sewage discharge process of mining pumps, there are often sundries mixed in the sewage. During the rotation of the impeller, ...

Problems solved by technology

At present, the mine pump motor used in the mine generates a lot of heat, which is easy to cause damage to the internal components of the motor shell and affects the normal use of the mine pump.

In addition, during the sewage discharge process of mining pumps, there are often sundries mixed in the sewage. During the rotation of the impeller, the blade of the impeller may be broken or broken by the sundries, which will affect the service life of the pump. At the same time, sundries often appear Blockage phenomenon
