Example Embodiment

[0010] The eccentric push circular distributed plunger pump of the present invention, such as Figure 1-Figure 2 As shown, it includes a box body 1, a plunger cylinder 2, a plunger 3, an output shaft 5, and a plunger pushing mechanism installed on the output shaft 5. The plunger cylinder 2 is installed on the box body 1, the plunger 3 and the plunger The cylinder cavity is matched, characterized in that the plunger pushing mechanism includes an eccentric wheel 6 mounted on the output shaft 5. The eccentric wheel 6 is in contact with the head of the plunger, and the plunger is provided with a return spring 4 and a return spring 4 Both ends are in contact with the spring holder 41 and the box body 1. The main structure of this technical solution includes the box body 1, the plunger cylinder 2, the plunger 3, the output shaft 5, etc. The plunger cylinder 2 is installed on the box body 1, the plunger 3 is installed in the plunger cylinder cavity, and the plunger 3 Driven by the pu...

Abstract

The invention discloses an eccentric push circumferentially-distributed plunger pump comprising a box body, a plunger cylinder, a plunger, an output shaft and a plunger pushing mechanism installed on the output shaft, wherein the plunger cylinder is installed on the box body, and the plunger is cooperated with the cavity of the plunger cylinder; the plunger pushing mechanism comprises an eccentric wheel installed on the output shaft, the eccentric wheel contacts with the head of the plunger, a return spring is arranged outside of the plunger, and two ends of the return spring contact with a spring retainer and the box body. The output shaft of the pump drives one eccentric wheel (cam) which pushes the plunger, and the plunger is reset by the spring. The product has simple structure, easy manufacture, delicate volume, small vibration, low noise and saved production cost. The technical scheme of the invention is suitable for producing multi-cylinder (multiplunger) products, such as double-cylinder products, three-cylinder products or four-cylinder products, five-cylinder products, six-cylinder products. The plunger pump is in circumferential distribution and saves power consumption, and the spring can perform the action of boosting. The complete machine has small volume and light weight, saves materials, can be carried by a single hand and is convenient to move.

Description

technical field [0001] The invention relates to a plunger pump, in particular to an eccentrically driven circumferentially distributed plunger pump. Background technique [0002] Piston pumps are widely used in supporting power sprayers and washing machines. The main structure of the existing plunger pump is that the power drives the crankshaft, the crankshaft drives the connecting rod, and the connecting rod drives the plunger. If it is a three-cylinder plunger pump, the three plungers are arranged in parallel. In the structure where the crankshaft and connecting rod drive the plunger, the disadvantages are that the processing of the crankshaft and the chain is troublesome and the cost is high; in addition, the power to drive the crankshaft is generally a gasoline engine, and the gasoline engine drives the crankshaft through a belt drive. The pulley in the belt drive is large in size. It is heavy, consumes a lot of materials, has high production cost, high vibration, and l...
