Description
Technical field
The present invention relates to a kind of motor power devices for being capable of providing hydraulic power.
Background technique
Hydraulic power in mechanical equipment using more and more extensive, be capable of providing the motor power device packet of hydraulic power
Motor and pump are included, motor realizes pump oil to pump drive.Due to there is liquid in pump, and it not can enter liquid inside motor,
Therefore just there is larger impact to the service life of motor to the leakage preventing structure between motor and pump.Chinese patent CN102868248A
A kind of " leakage preventing structure that pump shaft is held " is disclosed, motor includes electric machine casing, and pump includes the pump housing, electric machine casing, pump housing front and back
Arrangement, is provided with dynamic sealing mechanism, is provided with drain nut in shaft on front side of dynamic sealing mechanism between shaft and the pump housing, electricity
Position corresponding with drain nut offers annular groove on casing body, and the bottom of annular groove is provided with drainage hole.
In use, the liquid in pump can flow to the front side of dynamic sealing mechanism and enter if dynamic sealing mechanism reveals
It in annular groove, and is finally discharged by gravity through drainage hole, to avoid liquid continuation from staying to the inside of motor forward, certain
Play the role of protecting motor in degree.But this leakage preventing structure is only to be suitable for leaking few situation at present, works as infiltration
It leaks more serious, when saving bit by bit more liquid on front side of dynamic sealing mechanism, cannot be only discharged in time through drainage hole by gravity liquid, liquid
There are still the possibility for entering motor；In addition liquid is expelled directly out with will also result in certain pollution waste in external environment.
Chinese patent CN101749228A discloses a kind of " pump ", which includes pedestal, and the pump housing is provided on pedestal, pumps
Body has cylindrical hole inner cavity, and the pump rotor that pivot center extends along the longitudinal direction is provided in cylindrical hole inner cavity, and pump rotor is cut
There are at least two point of contacts in face and cylindrical hole inner cavity.The periphery of the pump housing is provided with hole, and guiding movement is equipped with baffle at hole, and baffle will
The hole is divided into inlet and liquid outlet, and rotor is cylinder, one end of partition and rotor outer periphery face sliding pushing tow cooperation.In use,
Pump rotor rotates clockwise, and the cavity of pump rotor two sides is communicated with inlet and liquid outlet respectively, wherein communicated with inlet
Cavity is low pressure chamber, and the cavity communicated with liquid outlet is high pressure chest, and partition guarantees low pressure chamber with rotor sliding pushing tow cooperation always
Obstructed with high pressure chest, during rotation, hydraulic oil is inhaled into low pressure chamber through oil inlet to rotor, with the rotation extruding of rotor
It is discharged through oil outlet, realizes pump oil.Pump has problems in that: rotor is driven by a motor and rotates, for corresponding motor, starting
Larger not only power consumption but also also larger to the loss of motor is loaded, and in the prior art, when electric motor starting in low pressure chamber also
Full of hydraulic oil, to complete to do work to hydraulic oil could complete the starting of motor, and this adds increased the starting loads of motor, not only
Cause lowest power when choice of electrical machine increased, also will affect the normal energy consumption of motor.
Summary of the invention
The purpose of the present invention is to provide a kind of motor power devices, to solve only to depend on gravity to cause to arrange in the prior art
Fluid apertures drainage capacity is limited, while liquid is expelled directly out the problem of will cause pollution waste.
In order to solve the above technical problems, technical scheme is as follows:
Motor power device turns including what device housing and the axis being set in device housing extended along the longitudinal direction
Axis is provided with dynamic sealing mechanism, is connected with rotor on front side of dynamic sealing mechanism in shaft between shaft and device housing,
Pump rotor is connected in shaft on rear side of dynamic sealing mechanism, is provided with drain on front side of dynamic sealing mechanism in device housing
Hole, device housing include electric machine casing and the pump housing, and the cross section of pump rotor and the pump housing have at least two point of contacts, be arranged on the pump housing
There are inlet opening and fluid hole, the partition being assemblied on the pump housing is directed between inlet opening, fluid hole and is separated, one end of partition and pump
The outer peripheral surface pushing tow of rotor cooperates, and the inner cavity of pump includes the low pressure chamber being connected to inlet opening and the high pressure chest that is connected to fluid hole,
Low pressure chamber is connected to the drainage hole, and fluid non-return valve and switch valve are provided on the communication path, in institute in device housing
It states and is provided with air inlet on front side of dynamic sealing mechanism, be connected with breather check valve on air inlet.
Drain nut is connected in shaft on front side of dynamic sealing mechanism, is provided in device housing opposite with drain nut
The annular groove answered, the drainage hole are set to the slot bottom of the annular groove.
The Oil Guide channel of connection pump rotor circumferential direction two sides is offered on pump rotor, also along pump rotor radially-directed in pump rotor
Mobile to be equipped with plugging block, plugging block has in its shift motion gets out of the way the first position in the Oil Guide channel and in centrifugal force
The second position in the Oil Guide channel is moved and blocked under effect outwardly, is provided on pump rotor to the plugging block application and is acted on
Power and force plugging block to be in the spring of first position.
The invention has the benefit that the present invention utilizes this impeller pump with low pressure chamber and high pressure chest,
When normal use, dynamic sealing mechanism is not leaked, and switch valve is closed at this time, and pump rotor works normally, and pump oil is realized, when dynamic sealing machine
Structure leaks, and when the liquid in pump flows on front side of dynamic sealing mechanism, switch valve is opened, by the effect of low pressure chamber by dynamic sealing
Liquid on front side of mechanism is drawn into low pressure chamber, waste problem is polluted caused by the one hand being expelled directly out to avoid liquid, separately
Outside since the low pressure of low pressure chamber acts on, the weight discharge of liquid no longer only on one's own account, therefore the drain energy of drainage hole can be improved
Power avoids saving bit by bit excessive liquid on front side of dynamic sealing mechanism and influencing motor service life.
Further, it when pump rotor does not rotate, is acted on by spring, plugging block is in first position, Oil Guide channel connection pump
The circumferential two sides of rotor, when pump rotor ground zero, since revolving speed is also relatively slow, centrifugal force is not enough to overcome the effect of spring
Power, therefore Oil Guide channel is still connected, the oil pressure of pump rotor circumferential direction two sides is consistent, therefore the starting load of pump rotor is smaller,
When the speed of pump rotor reaches certain value, the centrifugal force of plugging block overcomes the active force of spring, and plugging block is moved to outwardly
Two positions, Oil Guide channel are blocked, to realize normal fuel feeding.
