Stainless steel industrial pump, mining pump Submersible pump is our factory engineering and technical personnel under the current domestic coal mine drainage of the actual working conditions need to develop a new generation of high reliability, high-life replacement products.
1. Structural characteristics and working principle
A. Single-pump single-suction centrifugal pump structure, the use of high-efficiency dry motor, double shell structure (see diagram).
B. Pump part of the structure using single-suction centrifugal impeller and symmetric multi-chamber compression pump chamber. This structure can balance the radial force of the pump shaft to reduce the hydraulic impact. Another high-power pump pump parts are equipped with vice leaves, Vice-mouth ring and unloading holes and other balanced axial force structure, greatly extending the service life of the bearing. In addition the pumps are designed to stop the impeller can be washed to avoid the structure of the impeller.
C. The cooling mode of the pump is that the heat generated by the motor is transmitted to the motor case through the cooling air flow in the iron core and the motor case, and then flows through the water flow or airflow between the motor shell and the deflector shell When forced cooling. This method can ensure long-time idling and short-term overload operation does not burn the motor.
D. The pump uses the skeleton oil seal, the mechanical seal and the air chamber union seal form, the practice indicated that this kind of seal has the high reliability and the service life.
E. Electric pump structure is simple, easy to repair.
2. The main purpose and scope of application
Construction drainage of mine shaft and inclined shaft.
B. Mine waterless warehouse bottom drainage.
C. Drainage of mining face.
D. Vertical coal bunker drainage.
E. Clean the silo siltation sediment discharge.
F. Laotang, no man's land gushing water drainage.
G. Emergency relief.
H. Applicable to coal mine with methane dust explosion of gas.
3. Working conditions
A. The maximum dive depth is not more than 5m, the minimum depth should make the water network into the water.
B. Water temperature does not exceed 40 ℃.
C. The pH of the water is in the range of 4-10.
D. The volume concentration of water containing solid impurity is generally not more than 2%
E. The diameter of the solid particles in the water is not more than 50% of the smallest size of the cross section of the pump flow passage.
F. Working environment 0-40 ℃.
G. Work for the continuous working system.
