Abstract
The utility model relates to a self-cooled electric submersible pump which is a sucking type electric submersible irrigation and drainage device of which the water pump is positioned at the underside, and a motor is positioned at the upper part and combined together. The utility model is characterized in that the outer case of the motor is provided with an outer case cover of the motor, and the outer case is sheathed between the outer case cover and the water pump, and an interlayer hollow cavity is formed between the submersible pump body and the outer case. The sucked water flows into the interlayer hollow cavity through the outer case of the motor, and discharges from a water outlet on the outer case cover of the motor. As a result, the motor of the device has self flow water cooling, and the running of the motor exposed outside the water surface in a long time is guaranteed.
Description
The utility model relates to below a kind of water pump is positioned at, and motor is positioned at the electronic diving irrigation emitter unit of the lower suction type that is combined into one above.
The current lower suction type submersible electrical water pump that adopts all is that motor and water pump integrative-structure are sealed, and its drain opening is arranged on the water pump body.This submersible pump can only be in deep water normally operation, when water is shallow, motor surfaces, during long-play because motor itself does not have cooling unit, easy burn-out very.Therefore, this kind submersible electrical water pump exists drawback such as can not work, drainage efficiency is low in shallow water.
Task of the present utility model is to manufacture and design a kind of motor to have self-cooling set, dehydrating operation for a long time, not easy burn-out, and lower suction type submersible electrical water pump simple in structure.
The task that the utility model proposed is done in such a way that on the shell of motor soon establishes a motor housing cover, motor housing cover and motor housing be disjunctor together, drain opening is located on the motor housing cover.Between motor housing cover and water pump shell, a shell is set, one end of shell is enclosed within on the water pump shell, one end is enclosed within on the motor housing cover, be provided with seal ring between shell and the motor housing cover and between shell and the water pump shell, make shell, motor housing cover, motor housing, water pump shell surround an airtight interlayer cavity, the water outlet of water pump is located in the interlayer cavity, and is located at different sides with drain opening on the motor housing cover.When submersible electrical water pump was worked like this, water extruded from water outlet and enters the interlayer cavity, through the shell of motor, is discharged by drain opening.Even motor surfaces, still can obtain water cooling.If the gas that work still can extrude water pump when full dehydration is discharged by relief opening through motor housing, still can play certain cooling action.Above said motor housing, motor housing cover and the moulding of drain opening one-step casting, said seal ring can be sleeved on the seal groove of motor housing cover and water pump shell.Shell can be made with seamless steel pipe, relies on the fastening screw trip bolt of motor housing and water pump body that it is pressed between motor housing cover and the water pump shell.
The utility model is owing to adopted sandwich cavity structure, and the water that water pump extracts all pass through motor housing and discharges, and gives motor to cool off, and can guarantee the motor operation of surfacing for a long time.Even the water pump dry running, because air passes through from the interlayer cavity, motor equally can long-time running.Thereby, prolonged working life of submersible electrical water pump, improved working efficiency.
Fig. 1 is the schematic representation of the utility model sandwich cavity structure.
Fig. 2 is a structural representation of the present utility model.
Among the figure, the 1st, the shell of motor, the 2nd, motor housing cover, the 3rd, drain opening, the 4th, water pump shell, the 5th, shell, the 6,7, the 8th, seal ring, the 9th, interlayer cavity, the 10th, water outlet, the 11,12, the 13rd, seal groove, the 14th, motor, the 15th, water pump, the 16th, dirtproof cover, the 17th, chassis.
As can be seen from Figure, water is extruded by the water outlet 10 of water pump 15, enters interlayer cavity 9, through motor housing 1, discharges from drain opening 3.
