The liquid pump comprises a pump head connecting base with an eccentric hole, a cylindrical pump head body is mounted on the upper end face of the pump head connecting base in a sealed manner, and a water inlet and a water outlet are formed in the side wall of the pump head body; a rotor is rotatably mounted in the pump head body, a rotor shaft on the rotor is inserted into the eccentric hole, the annular outer wall of the rotor is tangent with the portion, located between the water inlet and the water outlet, of the inner wall of the pump head body, a guide groove is formed in the rotor, and a blade which can slide in the guide groove back and forth and matched with the size of the inner wall of the pump head body is inserted in the guide groove; a motor is fixedly mounted on the lower end face of the pump head connecting base, an output shaft of the motor is inserted into the eccentric hole and is fixedly connected with the rotor shaft, and a sealing cover is arranged on the top of the pump head body in a sealed manner; and the rotor shaft and the eccentric hole are rotatably connected in a sealed manner. The liquid pump is ingenious in design, a mounting hole of the rotor is arranged to the eccentric hole, in the rotating process of the rotor, the aims of water input and water output can be ingeniously achieved, and design is novel and unique.
Description
Technical field:
The invention mainly relates to a kind of liquid pump.
Background technology:
Liquid pump is conveying liquid or the machinery making fluid pressurization.It sends mechanical energy or other external energies of prime mover to liquid, liquid energy is made to increase, it is mainly used to carry liquid and includes water, oil, acid & alkali liquid, emulsion, suspended emulsion and liquid metal etc., it is possible to conveying liquid, admixture of gas and the liquid containing suspended solids.
The present invention provides a kind of liquor pump
Summary of the invention:
The object of the invention is contemplated to make up the defect of prior art, it is provided that the liquid pump of a kind of smart structural design.
The present invention is achieved by the following technical solutions:
A kind of liquid pump, it is characterised in that: including connecting seat with the pump head of eccentric orfice, pump head connects seat upper surface and is sealed and installed with the pump head body of tubular, and pump head body sidewall has water inlet and outlet；Being rotatablely equipped with rotor in pump head body, the armature spindle on rotor inserts in eccentric orfice, and annular outer wall and the pump head body inwall position between water inlet and outlet of rotor are tangent；Have gathering sill on described rotor, described gathering sill is fitted with blade that is that can within it slidably reciprocate and that mate with pump head body inner wall size；Described pump head connects seat lower surface and is fixed with motor, and the output shaft insertion eccentric orfice of motor is fixing with armature spindle to be connected；Described pump head body top seals lid equipped with sealing ring.
A kind of liquid pump, it is characterised in that: it is rotationally connected for sealing between described armature spindle and eccentric orfice.
A kind of liquid pump, it is characterised in that: it is separately installed with screw thread water nozzle on described water inlet and outlet.
The operation principle of the present invention is:
In present configuration, annular outer wall and the pump head body inwall position between water inlet and outlet of rotor are tangent, so, it is formed with A chamber between rotor, blade and the inwall of water inlet side pump head body, it is formed with C chamber between rotor, blade and the inwall of outlet side pump head body, between second half sidewall of rotor, blade and pump head body, is formed with B chamber.In motor process, A chamber constantly becomes big, produces negative pressure, thus is sucked liquid by K mouth, and in motor process, C chamber constantly diminishes, and produces pressure and is got rid of by J mouth by the liquid of C intracavity.In B cavity motor process, capacity keeps constant.Can change from each other in A chamber, B chamber and C chamber motor process, after blade S point slips over the M point of curve cavity, it is illustrated that C chamber can disappear, and produce new A chamber, it is illustrated that A chamber can be converted to B chamber, B chamber can be converted to C chamber.Thus summing up, A chamber is suction chamber, and B chamber is conversion chamber, and C chamber is for discharging chamber.
In present configuration, rotor is provided with gathering sill, and owing to the installing hole of rotor is eccentric orfice, so, in rotor rotation process, blade can slidably reciprocate the smooth rotation realizing blade in pump head body in gathering sill.
The invention have the advantage that
The present invention designs ingenious, by the installing hole of rotor is set to eccentric orfice, in rotor rotation process, achieves the purpose into water and water outlet dexterously, novel in design unique.
Accompanying drawing illustrates:
Fig. 1 is the STRUCTURE DECOMPOSITION figure of the present invention.
Fig. 2 is the vertical view cut away view of the present invention.
Detailed description of the invention:
See accompanying drawing.
A kind of liquid pump, connects seat 5 including the pump head with eccentric orfice, and pump head connects seat 5 upper surface and is sealed and installed with the pump head body 1 of tubular, and pump head body 1 sidewall has water inlet and outlet；Being rotatablely equipped with rotor 2 in pump head body, the armature spindle on rotor 2 inserts in eccentric orfice, and annular outer wall and pump head body 1 inwall position between water inlet and outlet of rotor 2 are tangent；Have gathering sill on described rotor, described gathering sill is fitted with blade 3 that is that can within it slidably reciprocate and that mate with pump head body inner wall size；Described pump head connects seat lower surface and is fixed with motor 6, and the output shaft insertion eccentric orfice of motor 6 is fixing with armature spindle to be connected；Described pump head body top seals lid equipped with sealing lid 4.
It is rotationally connected for sealing between armature spindle and eccentric orfice.
Screw thread water nozzle 7 it is separately installed with on water inlet and outlet.
The key point of the present invention is rotor curve movement in pump head body, and the curve that the present invention implements is the optimal case of motion smoothing.
