Abstract
The utility model discloses a submerged infusion pump capable of automatically adjusting inner cavity pressure of a motor. The submerged infusion pump comprises the motor. A communicated hole is formed in a shell of the motor, a breathing bag is arranged at the communicated hole on the outer side of the shell of the motor, and a bag cavity inside the breathing bag is communicated with an inner cavity of the shell of the motor through the communicated hole. During operation, if temperature and pressure of the interior of the shell of the motor are increased, pressure can be automatically relieved through the communicated hole, the volume of the bag cavity inside the breathing bag is increased, otherwise, the volume of the bag cavity inside the breathing bag is reduced and automatic adjustment is achieved, so that balance inside and outside the shell of the motor is finally maintained, the shell of the motor is prevented from stress and damage, leakage caused by stress and damage is avoided, and service life is prolonged.
Description
Technical field
The utility model relates to a kind of infusion pump, particularly a kind of submerged type infusion pump of self-regulation motor chamber pressure.
Background technique
Submerged type infusion pump when work is positioned at carries liquid, and as submersible pump, the operation by pump can suck water in the pump housing, then discharges by water pipe, reaches the purpose of pump water.Existing submerged type infusion pump comprises motor part and impeller train part, during the motor operation, and the rotor axis of electric rotation, and, by the blade movement of impeller train drive pump, sucked liquid and discharge liquid.The motor of actuated submersible pump comprises housing, housing is comprised of middle casing and the upper end cap and the lower end cap that are positioned at the middle casing two ends, rotor shaft by bearings in upper end cap and lower end cap central position and be provided with Sealing, rotor shaft is provided with rotor, the stator matched with rotor is located in middle casing, extend on the rotor shaft in the electric machine casing outside impeller train is installed, the impeller train is positioned at impeller housing, and impeller housing is connected with electric machine casing.The actuated submersible pump of this structure is the difference according to operating mode in when operation; electric machine casing inside often there will be the variation of temperature and pressure; when pressure increases, electric machine casing is bearing certain internal pressure, and electric machine casing inside also can produce negative pressure sometimes, has certain degree of vacuum.Time has been grown and has been easy to electric machine casing is caused damage, and finally causes sepage or leakage, thereby damages the coil of motor, has shortened the working life of pump.
Summary of the invention
The submerged type infusion pump of the self-regulation motor chamber pressure that the purpose of this utility model is to provide a kind of simple in structure, self-regulation motor chamber pressure, keep internal and external equilibrium, increase the service life, overcome the deficiencies in the prior art.
The submerged type infusion pump of self-regulation motor chamber pressure of the present utility model, comprise motor, be provided with intercommunicating pore on the housing of motor, be positioned at the intercommunicating pore place in the hull outside of motor and be provided with the breathing capsule, the blister cavities of breathing capsule inside is by the intracavity inter-connection of intercommunicating pore and electric machine casing.
The submerged type infusion pump of self-regulation motor chamber pressure of the present utility model, wherein said intercommunicating pore is located on the lower end cap that forms electric machine casing, and described breathing capsule is fastened in the outside of lower end cap.
The submerged type infusion pump of self-regulation motor chamber pressure of the present utility model, the outside that is positioned at the breathing capsule on the wherein said electric machine casing case that has been fastened is provided with open-work on case.
The submerged type infusion pump of self-regulation motor chamber pressure of the present utility model, during operation, electric machine casing is inner as temperature rise occurred, can automatically pass through the intercommunicating pore pressure release when pressure raises simultaneously, the inside blister cavities volume of breathing capsule is increased, otherwise the inside blister cavities volume of breathing capsule can dwindle, reach the purpose of automatic adjusting, finally kept the inside and outside balance of electric machine casing, make the unlikely pressurized of electric machine casing impaired, overcome the Seepage due to the impaired generation of pressurized, improved working life, can also play and prevent that motor coil from puncturing the unexpected Decrepitation Phenomena generation of moment housing.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1: electric machine casing is comprised of middle casing 3 and upper end cap 8, lower end cap 11, and rotor shaft 5 is supported on the central position of upper end cap 8 and lower end cap 11 by upper bearing (metal) 9 and lower bearing 10.The upper end of rotor shaft 5 extends the electric machine casing outside and establishes end seal 7, and the impeller train is equipped with in the outer end of rotor shaft 5, and the impeller train is positioned at impeller housing 6, and impeller housing 6 is connected with electric machine casing.Rotor shaft 5 is provided with rotor 4, and the stator 2 matched with rotor 4 is located at the inboard of middle casing 3.Be processed with intercommunicating pore 12 on lower end cap 11, in the outside of lower end cap 11, be fixed with breathing capsule 13, the inside blister cavities 14 of breathing capsule 13 is communicated with the inner chamber 1 of motor by intercommunicating pore 12.The material of breathing capsule 13 can be rubber or metallic material or other material, while selecting metallic material, should be made into the thin slice corrugated, so that stressed rear easy change shape, the volume of blister cavities easily changes.Be covered with case 15 in the outside of breathing capsule 13, be processed with open-work 16 on case 15.Case 15, breathing capsule 13, lower end cap 11, middle casing 3 can adopt flange and bolt connecting mode mutually to be fixedly clamped, and establish the sealing gasket sealing, also can adopt the mode that is fixedly connected with of other routine.The inner chamber 1 of motor and the inner chamber 14 of breathing capsule 13 can be filled with fluid (transformer oil) and add a certain amount of siccative.
During operation, electric machine casing is inner as temperature rise occurred, can automatically pass through intercommunicating pore 12 pressure releases when pressure raises simultaneously, inside blister cavities 14 volumes of breathing capsule 13 are increased, otherwise inside blister cavities 14 volumes of breathing capsule 13 can dwindle, reach the purpose of automatic adjusting, finally kept the inside and outside balance of electric machine casing, make the unlikely pressurized of electric machine casing impaired, overcome the Seepage due to the impaired generation of pressurized, improved working life, can also play and prevent that motor coil from puncturing the unexpected Decrepitation Phenomena generation of moment housing.
