Abstract
The utility model discloses a submersible pump with an inflating and water-proof motor, which arranges an inflating valve on the casing of a motor and arranges a pressure adjustment valve on the inflating valve on the basis of an existing submersible pump which is composed of the motor and an impeller pump which is connected with the shaft end of the motor. The air whose pressure is equal to the submerged water depth pressure is inflated into the sealing casing of the motor by the adjustment valve and the inflating valve to make the internal pressure and the external pressure of the casing of the motor keep basic balance so that the external water of the submersible pump can be prevented from leaking into the motor after the submersible pump enters into water, thereby, the destructions and faults of the motor, which are caused by the moisture of the motor can be avoided. The casing of submersible pump has simple sealing structure and good sealing effect, and the service life of the submersible pump is prolonged.
Description
The utility model relates to a kind of motor inflation water proof diving pump.
The existing submersible pump that draws water, utilize the casing enclosed construction that motor is sealed, time water inlet damages motor to prevent that submersible pump from working under water, its shortcoming is that the ageing resistance of reliability, working environment adaptability energy and Sealing to machinery requires all very high, thereby cause motor enclosed construction complexity, product cost improves, nonetheless, because the influence of processing and factor such as assembling, infiltration in poorly sealed, the machine and cause motor to damage being still the current main cause that submersible pump breaks down that influences.
The purpose of this utility model is the problem that exists at above-mentioned prior art and a kind of simple in structure, reliable operation is provided, can prevents the motor inflation water proof diving pump that motor damages because of water of infiltration preferably.
The technological scheme that realizes above-mentioned purpose is: a kind of motor inflation water proof diving pump, have the wing pump that motor and motor shaft end connect, and on the shell of motor, be provided with charging air inlet, on valve, dispose pressure-regulating valve.
The technical solution of the utility model also comprises: the tail end at motor housing is connected with air bag and air bag safety cover.
The utility model is owing to go into suitable pressurized air in that motor for submerged pump is envelope filled, and the pressure of water is in a basic balance outward can to keep pressure and the pump housing in the motor closed shell, thereby stops the infiltration of outside water effectively, prevents that motor from breaking down because of being subjected to humidity.Compare with the waterproof measure of existing submersible pump, simple in structure, leakage proof is effective.
Accompanying drawing is this motor inflation water proof diving pump structural front view.
The utility model is described in further detail below in conjunction with drawings and Examples.
Provide as accompanying drawing, this submersible pump has motor 1, is connected with centrifugal impeller pump 2 at motor shaft end, and the shell of motor is provided with charging air inlet 3, disposes pressure-regulating valve 4 on valve 3.Can in motor casing, inflate by charging air inlet, and by pressure-regulating valve according to slipping into the pressure that depth of water balance charges into gas, in a basic balance to guarantee the motor casing internal air pressure and the pump housing suffered water pressure of relative depth that pulls the plug.For the pressure that guarantees to charge into gas in a long time not because of leakage has bigger variation, can connect air bag 5 at the tail end of motor housing, the pressure that relies on the flexible maintenance of air bag to charge into gas is certain value substantially.Adding safety cover 6 in the outside of air bag 5 is used for air bag is protected.Air bag 5 can adopt dish-shaped rubber tube shrinking structure, and can add helical spring on rubber tube, to improve the rigidity of air bag, increases ability adjustment.
Claims (2)
1, a kind of motor inflation water proof diving pump comprises the wing pump (2) that motor (1) and motor shaft end connect, and it is characterized in that: be provided with charging air inlet (3) on the shell of motor (1), dispose pressure-regulating valve (4) on this valve.
2, motor inflation water proof diving pump according to claim 1, it is characterized in that: the tail end at motor (1) shell is connected with air bag (5) and air bag safety cover (6).
