Description
Technical field
The present invention relates to a kind of movable pump stations.
Background technique
At present since many sewerage system design standards in China are too low, drainability wretched insufficiency improves city as early as possible
City controls flood and drains flooded fields ability, it has also become the task of top priority of Chinese Urbanization development, therefore the movable pump station as emergency flood fighting just rises
Critical effect is arrived.Existing movable pump station includes automobile and the vehicle-mounted pumping plant that is set on automobile, the master of vehicle-mounted pumping plant
Wanting component part is motor and pump, therefore the performance of motor and pump just decides the performance of movable pump station.
A kind of existing pump " pump " as disclosed in Chinese patent CN101749228A, which includes pedestal, is arranged on pedestal
There is the pump housing, the pump housing has cylindrical hole inner cavity, is provided with the rotor that pivot center extends along the longitudinal direction, rotor in cylindrical hole inner cavity
Section and cylindrical hole inner cavity there are two point of contact.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,
Rotor clockwise rotation, the cavity of rotor two sides is communicated with inlet and liquid outlet respectively, wherein the wall communicated with inlet
For low pressure chamber, the cavity communicated with liquid outlet is high pressure chest, and partition guarantees low pressure chamber and height with rotor sliding pushing tow cooperation always
Press chamber obstructed, during rotation, hydraulic oil is inhaled into low pressure chamber through oil inlet to rotor, with the rotation extruding of rotor through going out
Hydraulic fluid port discharge, realizes pump oil.Existing this pump has problems in that: rotor is driven by a motor and rotates, corresponding motor and
Speech, the larger not only power consumption of starting load but also also larger to the loss of motor, and in the prior art, when electric motor starting in low pressure chamber
Also hydraulic oil is filled with, to complete to do work to hydraulic oil could complete the starting of motor, and it is negative that this adds increased the startings of motor
It carries, lowest power when not only resulting in choice of electrical machine increased, and also will affect the normal energy consumption of motor.
Summary of the invention
The purpose of the present invention is to provide the movable pump stations that one kind can reduce electric motor starting load.
In order to solve the above technical problems, technical scheme is as follows:
Movable pump station, including automobile and the vehicle-mounted pumping plant being set on automobile, vehicle-mounted pumping plant includes motor and is driven by motor
Dynamic pump, pump include the pump housing with cylindrical hole inner cavity, and pivot center extends along the longitudinal direction, cross section is provided in the pump housing
For elliptoid rotor, the cross section of rotor and bore tool are provided with inlet opening and fluid hole on the pump housing there are two point of contact,
It is separated between inlet opening, fluid hole by partition, one end of partition and rotor outer periphery face sliding pushing tow cooperation, the major diameter direction of rotor
Both ends are provided with the Oil Guide channel of connection rotor circumferential direction two sides, and also along major diameter direction, guiding movement is equipped with plugging block in rotor,
Plugging block in its shift motion have get out of the way the Oil Guide channel first position and move outwardly under the action of the centrifugal force and
The second position in the Oil Guide channel is blocked, is provided on rotor to the plugging block and is applied active force and plugging block is forced to be in
The spring of first position.
The spring is the pressure spring being set on the outside of plugging block.
On-vehicle battery is additionally provided on automobile, on-vehicle battery is with the motor for being electrically connected.
Vehicle-mounted pumping plant further includes being set to the motor protecting crust peripheral with pump, is connected separately on inlet opening, on fluid hole
The pipeline being pierced by by the protecting crust.
The invention has the benefit that being acted on when rotor does not rotate by spring, plugging block is in first position, Oil Guide
The circumferential two sides of channel connection rotor, when rotor ground zero, since revolving speed is also relatively slow, centrifugal force is not enough to overcome spring
Active force, therefore Oil Guide channel is still connected, the oil pressure of rotor circumferential direction two sides is consistent, therefore the starting load of rotor is smaller,
When the speed of rotor reaches certain value, the centrifugal force of plugging block overcomes the active force of spring, and plugging block is moved to second outwardly
Position, Oil Guide channel are blocked, to realize normal fuel feeding.
