MD wear-resistant multi-stage centrifugal pump for mining
Overview
MD type mining wear-resistant multi-stage centrifugal pump is a horizontal single-suction multi-stage segmented/segmented centrifugal pump. The multi-stage pump manufacturer, Zoomlion Pumps, adopts the hydraulic model of energy-saving products recommended by the state. A high-pressure multistage centrifugal pump dedicated to the mining industry. It has the advantages of high efficiency, wide performance range, safe and stable operation, low noise, long life, convenient installation and maintenance, etc. This type of multi-stage centrifugal pump for mining is used to transport neutral mineral water (particle size less than 0.5 mm) with a solid particle content of not more than 1.5% and other similar sewage. Steel plants, mine drainage, sewage transportation and other occasions.
Applicable conditions
1. Under the condition of clean water (with solid particles less than 0.1%), the efficiency will not drop by more than 6% after running for 5000h without overhaul;
2. Under the condition of sewage containing solid particles below 0.1% to 1%, running for 3000h without overhaul, the efficiency drop does not exceed 5%;
3. Under the condition of sewage containing 1-.5% solid particles, the efficiency will not drop by more than 6% if it runs for 2000h without major repairs.
Feature introduction
The stator part of the multistage pump is mainly composed of the front section, the middle section, the guide vane, the rear section, the bearing frame and the balance chamber cover. superior.
The rotor parts are mainly made of impeller, impeller block, balance block, balance disc and shaft sleeve parts are tightened with small round nuts, and are fixed on the shaft with flat keys to prevent rotation. The entire rotor is supported on bearings at both ends. The rotor is directly connected to the motor with an elastic pin coupling.
