Description
Technical field
The utility model relates to a kind of filling type submersible electric motor, relates in particular to a kind of filling type submersible electric motor that has pressure relief device.
Background technology
Immersible pump finds broad application in daily life, the water pump on generally including submersible electric motor and being connected it.Because submersible electric motor works in rugged environment for a long time, determined it to the performance of hermetically-sealed construction and have relatively high expectations, also to take into account heat radiation cooling requirement.Existing filling type submersible electric motor is in order the bearing on the motor and the machinery that is positioned at the motor stator top of chamber to be carried out seal lubrication and to play about cooling, so oiling is many.But the oiling cavity volume in the existing filling type submersible electric motor is little, because reason temperature rises such as overload when too high, cavity pressure will increase, and then the destruction motor seal when motor, even causes harm such as aircraft bombing.
Summary of the invention
The purpose of the utility model is to provide a kind of filling type submersible electric motor that has pressure relief device; Setting through pressure regulator membrane; Can adjust the volume in oiling chamber according to the pressure in the oiling chamber automatically; Solve the little and oiling cavity volume of oiling cavity volume that prior art exists and fix, when cavity pressure increases, destroy sealing easily even cause problem such as aircraft bombing.
The above-mentioned technical purpose of the utility model mainly solves through following technical scheme: a kind of filling type submersible electric motor that has pressure relief device; Comprise housing, the upper shell cover and the lower cover that are installed on the shell block two ends and mate respectively with respective end; Be arranged on the rotating shaft in the housing; The rotor and the stator that are arranged in the housing and cooperatively interact through rotating shaft; And upper bearing (metal) and top chock and lower bearing and the step of accepting the rotating shaft two ends respectively, said rotating shaft is passed rotor and is extended to the upper shell cover outside, and said rotating shaft forms shaft seal with upper shell cover and cooperates; It is characterized in that pressure relief device, said pressure relief device cooperates with step makes the housing inner chamber be closed cavity.Set up pressure relief device (like pressure regulator membrane) in motor bottom, pressure relief device is cooperated with step form motor cavity (being the housing inner chamber) oil seal, utilize pressure relief device to cooperate and form the pressure regulation cavity with lower cover.Under the situation that does not influence the lubricated and cooling of upper bearing (metal) and mechanical seal, increase the pressure regulation cavity on the motor.When the motor cavity temperature raises, when machinery oil expands,, increase the volume of motor cavity through pressure relief device compression pressure regulation cavity, reach the pressure release effect, prevent that the sealing of motor is damaged, avoid occurring the aircraft bombing phenomenon, improve motor performance safe in utilization.Wherein, to be arranged on motor bottom be good to pressure relief device.Certainly; In practical application, also can be arranged between upper shell cover and the top chock, but since machine shaft outside motor top extends in, so need be to carrying out oil seal between pressure relief device and the machine shaft; To this; Need set up more parts, and during pressure regulation, destroy the oil seal between pressure relief device and the machine shaft easily.Therefore, comparatively speaking, pressure relief device is arranged on motor bottom, and is simple in structure, the pressure regulation good reliability.
As the further of technique scheme improved and replenish, the utility model adopts following technical measures:
Has the pressure regulation cavity between said pressure regulator membrane and the lower cover.The setting of pressure regulation cavity makes the pressure regulator membrane both sides have pressure differential, makes things convenient for the pressure regulator membrane pressure regulation.
As preferably, said pressure relief device comprises pressure regulator membrane, and said pressure regulator membrane cooperates with step makes the housing inner chamber be closed cavity.
Along being provided with the bearing inner concave, said pressure regulator membrane overlaps on the bearing inner concave through the flanging at its edge in the outer surface of said step, and said flanging is by step and lower cover clamping and fixing.Through step and lower cover clamping and fixing pressure regulator membrane, assembling simply, and through the clamping flanging; Make flanging form the effect that elastic deformation reaches elastic seal ring, avoid reusing of elastic seal ring, help simplified structure; Reduce the effect of parts, play the effect of sealing simultaneously again.Therefore, pressure regulator membrane has the effect of pressure regulation and sealing simultaneously.
The edge of said flanging is provided with positioning convex, is provided with positioning spigot corresponding to the positioning convex place on the said bearing inner concave, and said positioning convex is planted with positioning spigot and cooperated.Positioning convex cooperates with the plant of positioning spigot; When avoiding the pressure regulator membrane pressure regulation; The stressed generation of flanging displacement the and then influence installation reliability of pressure regulator membrane avoids the flanging displacement to reduce sealing effectiveness, pressure regulator membrane breaks away from and grips when serious, and the effect of destruction pressure regulation and sealing.
In order to make flanging on the pressure regulator membrane play the effect of sealing ring, still have certain thickness after the elastic deformation that clamping forms and play sealing function: the said positioning spigot degree of depth is less than flanging thickness.
Have enough elastic deformation abilities in order to improve pressure regulator membrane, said pressure regulator membrane is provided with the outer arch of pressure regulation.
The outer arch of said pressure regulation is interior along being provided with along flanging.
The beneficial effect that the utlity model has: 1, set up pressure regulator membrane, pressure regulator membrane is cooperated with step form the motor cavity oil seal, utilize pressure regulator membrane to cooperate and form the pressure regulation cavity with lower cover in motor bottom.Under the situation that does not influence the lubricated and cooling of upper bearing (metal) and mechanical seal, increased the pressure regulation cavity on the motor.When the motor cavity temperature raises, when machinery oil expands,, compress the pressure regulation cavity through the deformation of pressure regulator membrane, increase the volume of bore of stator, reach the pressure release effect, prevent that the sealing of motor is damaged, avoid occurring the aircraft bombing phenomenon, improve motor performance safe in utilization.2, flanging promptly is that the installing and locating portion of pressure regulator membrane is again a sealing, and the structure of therefore simplifying has been simplified parts, helps improving the reliability and the safe shape of use; 3, stable for pressure regulator membrane is gripped, cooperate with the plant of positioning spigot through positioning convex, avoid the use of the displacement of process, further improve the reliability and the safe shape of using.
