Abstract

The invention relates to the field of liquid pumps and in particular relates to an eccentric type liquid pump. A pump core shaft rotate oppositely in a single direction from a liquid inlet to a liquidoutlet, so that three groups of chamber division plates and a liquid separation block on a rotary shaft rotate; the rotary shaft is located at an eccentric position, the liquid separation block at one side, which has the shortest distance from the rotary shaft, of a shell body is at a closed state all the time; when the rotary shaft rotates through the shortest side, the liquid separation block is slowly opened through an external expansion spring, and the liquid separation block and an inner surface of the shell body keep a tangential state; a space formed by the chamber division plates andthe liquid separation block slowly becomes large, so that liquid flows into the shell body from the liquid inlet; when the liquid separation block rotates until the distance between the shell body andthe rotary shaft is the greatest, liquid in the space formed by the chamber division plates and the liquid separation block is saturated; after the rotary shaft passes through the position, the liquid is discharged from the liquid outlet; the motion is circulated to realize the function of the liquid pump; a driving force can be effectively reduced under the action of the external expansion spring; when the load on the liquid pump is relatively great, the external expansion spring is forced to be retracted, so that the liquid inlet and the liquid outlet are communicated and pressure leakage is realized.

Description

technical field [0001] The invention relates to the field of liquid pumps, in particular to an eccentric liquid pump. Background technique [0002] At present, a pump is a machine that converts the mechanical energy of a prime mover into the energy of a liquid. The prime mover drives the impeller to rotate through the pump shaft, and works on the liquid to increase its energy, so that the liquid is transported to a high place or a place that requires pressure. [0003] Pumps are mainly used to transport liquids such as water, oil, acid and alkali liquids, emulsions, suspoemulsions, and liquid metals. They can also transport liquids, gas mixtures, and liquids containing suspended solids. However, the structure of conventional pumps is relatively complicated, and the power source is The work done by the motor, when the working pressure is high, the impeller will not be protected from overload, resulting in a shortened service life of the pump.
