Abstract
The utility model discloses a high-efficiency temperature-resistant bidirectional fluid pump, which relates to a liquid feeding pump used on the lubrication systems of drilling wells and machine tools as well as in the industries of petroleum, chemicals, medicines, foodstuff, etc. The utility model is characterized in that a crescent part (4) used for changing direction is arranged in the clearance of the engagement between a guide wheel (6) and a gear at the front end of a transmission wheel shaft (2). Consequently, no matter whether an input shaft rotates in a positive or reverse direction, a direction-changing structure in the pump body always maintains the outlet and inlet of the pump in the same state, and therefore the high-efficiency fluid pump can satisfy the requirements of production. The purpose of the utility model is to resolve the problem of that the fluid pump cannot be regulated because of the positive and reverse rotations of the input shaft. The utility model has the advantage of that, no matter how the direction of the imported power is changed, the direction of the liquid-exporting outlet is not changed; the temperature-resistant range is between 0 to 150 DEG C; the pressure of the exported liquid is steady, and flow is stable; damageable parts are few, and overhaul is convenient; the occupied area is small, and noise is low.

Three, summary of the invention:
1, goal of the invention: the utility model provides a kind of efficient heatproof bidirectional fluid pump, and its purpose is to solve because the fluid pump that the input shaft forward and backward causes can't be adjusted the problem that this respect exists.
2, technological scheme: the utility model is achieved through the following technical solutions:
A kind of efficient heatproof bidirectional fluid pump, this fluid pump comprises left and right end cap, guide wheel, adjusting pad, pump case, liquid inlet and outlet, power axle; Left and right end cap and pump case constitute the cavity of pump, and the liquid inlet and outlet on the pump case is communicated with cavity in the pump case, and guide wheel is located on the guide wheel shaft of cavity inner driving wheel axle front end, and the power axle front end is to be located at the interior gear structure of cavity, is meshed with guide wheel; It is characterized in that: be provided with at the gap location of the gear engagement of guide wheel and power axle front end and be used to the crescent moon spare that commutates.
Crescent moon spare rotates 180 ° around guide wheel during commutation in the cavity of pump case.
Liquid inlet and outlet forms when the pump housing commutates, liquid entering hole.
The gear of power axle front end is an internal gear, and guide wheel is an external gear.
3, advantage and effect: by the enforcement of technical solutions of the utility model, can solve existing fluid pump well, inoperable problem during the line shaft backward rotation.
The characteristics of the efficient heatproof bidirectional fluid of the utility model pump:
1. no matter import power direction and how to change, the direction of output liquid outlet is constant;
2. temperature resistant range is wide 0～150 ℃;
3. the pressure of exporting fluid is steady, stability of flow;
4. few easy workout part, easily maintenance;
5. take up an area of for a short time, noise is low.
Four, description of drawings:
Accompanying drawing 1 is the utility model efficient heatproof bidirectional fluid pump work schematic diagram when just changeing clockwise;
Accompanying drawing 2 is the utility model efficient heatproof bidirectional fluid pump work schematic diagrams when reversing counterclockwise;
Accompanying drawing 3 is the efficient heatproof bidirectional fluid of the utility model pump general assembly system diagrams.
Five, embodiment:
Below in conjunction with accompanying drawing concrete structure of the present utility model is described in detail as follows.
Each component names of fluid pump among the figure: 1, left end cap; 2, power axle: 3, spring pad; 4, crescent moon spare; 5, regulate pad; 6, guide wheel; 7, pump case; 8, regulate pad; 9, liquid entering hole; 10, liquid outlet: 11, right end cap.
Shown in accompanying drawing 1,2, the utility model is a kind of fluid pump, be a kind of gear pump specifically, liquid is in liquid entering hole 9 enters into the pump cavity that is made of left and right end cap 1,11, pump case 7, the liquid that enters pump chamber is discharged along liquid outlet 10 after after the internal gear of power axle 2 front ends and guide wheel 6 engagements flowing liquid being increased kinetic energy.I.e. no matter power axle 2 forwards or reverse rotation, the liquid of being carried is gone into from liquid entering hole 9 all the time, goes out from liquid outlet 10.The concrete structure of this pump as shown in Figure 3, it comprises left and right end cap 1,11, guide wheel 6, spring pad 3, regulates pad 5, pump case 7, liquid inlet and outlet 9,10, power axle 2; Left and right end cap 1,11 and pump case 7 constitute the cavity of pump, cavity in liquid inlet and outlet 9,10 on the pump case 7 and the pump case 7 is communicated with, guide wheel 6 is located on the guide wheel shaft of cavity inner driving wheel axle 2 front ends, and power axle 2 front ends are the inner gear structure that is located in the cavity, are meshed with guide wheel 6; Be provided with in the gap of guide wheel 6 and the internal gear of power axle 2 front ends and be used to the crescent moon spare 4 that commutates.During power axle 2 forward rotation, crescent moon spare 4 is at the internal gear of power axle 2 front ends and above guide wheel 6 engagement places, after crescent moon spare 4 rotates 180 ° during commutation in the gap of the internal gear of power axle 2 front ends and guide wheel 6 engagements, if power axle 2 directions are rotated on the contrary, then driven guide wheel 6 and crescent moon spare 4 also will be once more Rotate 180 °, commutation passage before is a liquid outlet 10 to make liquid stream still import to not, because the integral body of pump is the metal manufacturing, so temperature tolerance is better.
Working principle of the present utility model is as follows:
When A, pump startup, in the pump cavity at liquid entering hole 9 places, the guide wheel 6 of engagement and the internal gear of power axle 2 front ends separate gradually, produce certain vacuum herein, liquid is sucked pump chamber from liquid entering hole 9 pipelines, the internal gear of power axle 2 front ends of rotation passes through crescent moon spares 4 with liquid from pump liquid entering hole 9, be transported to pump liquid outlet 10 ends, guide wheel 6 meshes gradually with the internal gear of power axle 2 front ends, and the backlash reduces, and the pressure of generation is sent the pump housing with liquid through liquid outlet 10.
The two-way function of B, uniqueness:
See Fig. 2 when the sense of rotation of pump is counterclockwise from becoming clockwise, guide wheel 6 and crescent moon spare 4 be Rotate 180 degree simultaneously also.Like this, the flow direction of liquid also changes in the pump, and for the user, the sense of rotation that external performance is pump changes and the import and export of pump are constant.In case turning to once more of pump changes, driven guide wheel 6 and crescent moon spare 4 are also incited somebody to action Rotate 180 degree once more.Thereby realize commutating and see Fig. 1., no matter how forward and backward commutates the input line shaft repeatedly in operation process, and the liquid of carrying is still by the constant a kind of efficient bidirectional fluid of former technology throughput direction.
