For achieving the above object, the technical solution adopted in the utility model is: described proof submersible sand discharging pump comprises pump, Connection Block and submersible motor, wherein pump comprises the pump housing, pump cover, impeller and mechanical seal, Connection Block is fixedly connected with pump cover with the pump housing, submersible motor is fixed on Connection Block, and described cooling device comprises sleeve, water inlet pipe and outlet pipe; Described jacket casing is located at the submersible motor outside, and its lower end and Connection Block are tightly connected, and upper end is connected with the body seal of submersible motor, forms a cooling chamber between described sleeve lining and submersible motor outer wall; Described Connection Block, pump cover and the pump housing offer the water inlet flow channel be connected, and this water inlet flow channel communicates with the high pressure chest in the pump housing; Described water inlet pipe is located in cooling chamber, and is connected with water inlet flow channel; Described outlet pipe is located at the top of sleeve periphery, one end and communicating with cooling cavity, and the other end stretches out outside cooling chamber.
Related content in technique scheme is explained as follows:
1,, in such scheme, the water inlet of described outlet pipe is positioned at the top of the stator core of submersible motor.
2,, in such scheme, the delivery port of described water inlet pipe is lower than the water inlet of outlet pipe.
3,, in such scheme, the top of described water inlet pipe is fixedly connected with the shell of submersible motor by a connection piece.Described connector comprises base, screw and sleeve pipe, and described sleeve pipe and base are structure as a whole, and water inlet pipe is positioned at sleeve pipe.
4,, in such scheme, described sleeve lower end is connected with Connection Block by a stepped ramp type base, sleeve and the welding of stepped ramp type base, and the stepped ramp type base is fixedly connected with by screw rod with Connection Block.
The utility model operation principle is: the water inlet flow channel that the water inlet pipe of cooling device forms by the pump housing, pump cover and Connection Block three communicates with the high pressure chest of the pump housing, when pump turns round, current automatically enter and in cooling chamber between motor housing and cooling cover, motor are carried out coolingly, reduce motor temperature.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, because the utility model utilizes the water in pump, submersible motor is dispelled the heat, can complete motor radiating so only need to flood the impeller of lowest part in pump during water pump operation, do not need to flood fully whole submersible motor, therefore dredge pump is not subject to the restriction of height of liquid level, can guarantee the normal operation of submersible motor;
2, due to the utility model sheathed cooling cover outside submersible motor only, between cooling cover and motor housing, water inlet pipe is set, simple in structure, be suitable for transforming existing proof submersible sand discharging pump.
