Abstract

The invention relates to a variable pressure adjustable rotation pump which delivers liquid and gas or pressurizes the liquid and the gas by change of working volume formed between two adjacent oar blades on a rotor and a pump cylinder when the rotor rotates. The adjustable variable vane pump is characterized in that each oar blade is provided with a 90-degree rotation angle to achieve the doing compression state and the rotation state when the oar blade finishes the compression work and meets a protruding block. The vane pump with the rotating oar achieves variable control by lifting or pressing down a separation strip.

Description

Regulated variable turns the blade wheel pump

The present invention is that a kind of blade has 90 degree autorotation angles, regulated variable turn the blade wheel pump.

At present, liquid pump is a lot of on market with the product category of air pump, functional advantage has his own strong points, but seldom has product can have simultaneously: variable is adjustable, efficient is high, simple in structure, rotational velocity is low, noise is little, discharge capacity is large and these several aspects of not pulsing.

In order to have above several respects advantage simultaneously, through years of researches experiments, I invent a kind of it be the variation conveying liquid of formed swept volume between adjacent two blades on pumping cylinder and the rotor during with rotor. gas or make it supercharging and the rotary pump Variable quantity pressure regulation.Its feature is: have 90 degree autorotation angles, the left and right sides to realize doing manual work compressive state with the turn state of finishing when running into projection after the compression work with each blade, mention or depress that dividing strip just can realize Variable Control turn the blade wheel pump.

The below is in conjunction with main accompanying drawing, disassembled view, and criss-crossing blade and rotor main shaft broken away view, each figure such as dividing strip detail drawing comes working principle further instruction of the present invention.

Fig. 1 is main accompanying drawing of the present invention.

Fig. 2 is disassembled view

Fig. 3 is criss-crossing blade and rotor main shaft broken away view

Fig. 4 is the dividing strip details drawing

Fig. 5 turns blade wheel pump break to take side cover plate view on one side apart

Among the figure, 1. 4. import exports of the filling blade on criss-crossing blade 2. rotor main shafts 3. main shafts, 5. dividing strips, 6. projections, 7. side cover plates, 8. import exports, 9. bearing supports

When rotor main shaft rotated blade on one side by projection, the edge was pushed up by projection, can turn 90 degrees with projection bent face cunning, and in this process, the blade of opposite end has also rotated 90 degree simultaneously, and the blade face is vertical with the both sides capping, forms piston, begins to do compression work.Wherein dividing strip mention or press control the capacity of reflux of compressed (gas, liquid), when dividing strip is pressed onto the end, dividing strip only allows blade follow the filling blade on the main shaft to pass through, compressed (gas, liquid) can not be back to import by dividing strip, can only discharge from exhaust port.As dividing strip is mentioned, then compressed (gas, liquid) some meeting refluxes from the dividing strip space, control exactly dividing strip passes through dividing strip with the spacing change of main shaft (gas, liquid) the capacity of reflux size obtains the relevant pressure of exhaust port, realizes that variable is adjustable.When mentioning dividing strip fully, just there is not dividing strip to block compressed (gas, liquid), so compressed (gas, liquid) all be back to import and make circular movement at the pump housing always, exhaust port just can not get dividing potential drop, there is not pressure, at this moment pump idle running is not done manual work, except friction produces some resistances, other can not produce any resistance, according to its these characteristic, can also make one to it and brake without frictional force but turn blade wheel pump break with what a simple dividing strip controlled that liquid backflow amount in the sealing pump housing realizes braking, see Fig. 5.

Beneficial effect following points of the present invention:

1, with regard to a main shaft, there is not clump moving gear, clump moving axis etc.Style of work power is direct, and starting is fast.

2, it is by the variation of formed swept volume between adjacent two blade sheets on pumping cylinder and the rotor

3, carry liquid or make it supercharging, and blade is the motion of circle line in the compression work interval of pumping cylinder, so the not pulsation of flow heel pressure.

4, reversible is anti-, and outlet follow-up mouth structure is identical, makes pneumatic motor, and is most effective during fluid motor.

5, the interior blade sheet of pump is subjected to the synergy of centrifugal force, mechanical thrust, liquid gas pressure power, in the motion of pumping cylinder inner circle-line, thereby makes pump have unique high efficiency.

6, do not required taking out object (oil. water. gas) all right.

7, it is fine to turn the paddle balance condition, does not have valve.

Claims

One kind it be during with rotor on pumping cylinder and the rotor between adjacent two blades the variation of formed swept volume come conveying liquid. gas or make it supercharging and the rotary pump Variable quantity pressure regulation.Its feature is: have 90 degree autorotation angles, the left and right sides to realize doing manual work compressive state with the turn state of finishing when running into projection after the compression work with each blade, mention or depress that dividing strip just can realize Variable Control turn the blade wheel pump.
2. rotary pump according to claim 1 is characterized in that: 4 blades are rotatable 90 degree just separately, have 90 degree autorotation angles, the left and right sides to realize doing manual work compressive state with the turn state of finishing after compression work is run into projection with each blade.
3. rotary pump according to claim 1 is characterized in that: control dividing strip and follow the spacing of main shaft to change by the gas of dividing strip, the relevant pressure that liquid capacity of reflux size obtains exhaust port, realize that variable is adjustable.
