Abstract
The utility model discloses a mining flameproof sand-flushing electric diving pump, which comprises an electric motor, an impeller, a guide vane, a sealed chamber, a delivery chamber, a cooling cavity, a water inlet and a water outlet. The electric motor is arranged in the cooling cavity, while the impeller is fixed on the output shaft of the electric motor and the sealed chamber is fixed on the lower end cover of the electric motor. The sealed chamber is sleeved on the output shaft of the electric motor, while the sealed chamber is provided with a mechanical seal. The electric motor realizes water cooling on the condition that water is provided and realizes wind cooling on the condition that water is not provided so as to solve the problem that the electric motor is prone to be heated and then burned out. The delivery chamber, impeller and the guide vane all apply the bulb iron material with a good wearing resistance so as to prolong the service life.
Description
(1) technical field
The utility model relates to a kind of pump, and husky Submerged Motor Pumps is arranged in place such as pick face and tunnel under particularly a kind of coal mine that is used to have explosion risk.
(2) background technique
The conveying of flowing medium often relies on pump to transmit, and it is little that general service pump has clean waterpump, sewage pump, clean waterpump mainly to be applicable to require quantity delivered, pressure head height, and the little liquid of viscosity, and it is lower that sewage pump is used for large particle pump transfer efficiency, and working life is short.And sand discharging pump is a kind of conveying sand content height, and wear-resisting, dry running can be air-cooled, the fortune of can dewatering, the high long service life of efficient, is very suitable for place such as pick face and tunnel under the coal mine.Present sand discharging pump is deposited some shortcomings, and the one, the motor feels hot, and the back is difficult for cooling, and the 2nd, wear no resistance, thereby cause working life short.
(3) summary of the invention
The technical problems to be solved in the utility model is: provide a kind of motor to cool off easily, wear-resisting flame-proof mine is arranged husky Submerged Motor Pumps.
In order to solve the problems of the technologies described above, the utility model comprises motor, impeller, stator, closed chamber, delivery chamber, cooling chamber, water intake and water outlet, described motor is in cooling chamber, impeller is fixed on the output shaft of motor, closed chamber is fixed on the lower end cap of motor, closed chamber is enclosed within on the output shaft of motor, and mechanical seal is arranged in the closed chamber.
In order to improve wear resistance, described impeller and stator have two to quadruplet, and impeller and stator all are in the delivery chamber, and all impellers all are fixed on the output shaft of motor, and delivery chamber, impeller and stator all adopt ductile iron material.
The beneficial effects of the utility model are: motor of the present utility model is having water-cooled under the regimen condition, air-cooled under anhydrous situation, solved motor easily heating and the problem that burns out, delivery chamber, impeller and stator all adopt ductile iron material, wear resistance is good, has prolonged working life.
