Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0018] Such as figure 1 As shown, a high-efficiency positive displacement pump provided by the present invention includes a casing 1, a motor 27, a worm 4, a worm wheel 29, an eccentric shaft 30, a shaft 20, and a pump head. The motor 27 is connected to the worm 4 through a worm sleeve 2, and the worm sleeve 2 and the worm 4 are fixed by the pin 3, the lower end of the worm is positioned and connected with the chassis 1 through the first bearing 5, after starting the motor 27, the worm 4 is driven...

Abstract

The invention provides a high-efficiency positive displacement pump. The high-efficiency positive displacement pump comprises a case, a motor, a worm, a worm gear, an eccentric shaft, a shaft and a pump head; the motor is connected with the worm rod by use of a worm sleeve; the lower end of the worm is positioned and connected with the case by use of a bearing; the worm drives the worm gear to rotate; the worm drives the eccentric shaft to rotate; the eccentric shaft drives the shaft to reciprocate in the pump head; the pump head comprises a left pump head and a right pump head, the two of which are arranged oppositely and connected by use of a sliding sleeve. Compared with the prior art, the high-efficiency positive displacement pump has the beneficial effects that the dual-pump head structure is adopted so that a liquid can be suctioned and discharged twice in one working period of the connecting rod, and the working efficiency is doubled in contrast with the prior art, the impact problem of engagement is overcome, the impact of toothed surfaces is avoided and no impact noise is generated, and therefore, the service life of the pump can be prolonged to a large extent.

Description

technical field [0001] The present invention relates to pumps, in particular to a high efficiency positive displacement pump. Background technique [0002] Positive displacement pump is a kind of working parts such as piston, plunger, diaphragm, gear or vane to reciprocate or rotate in the pump body, so that the volume of several working chambers in the pump body changes periodically, and alternately sucks and discharges. A pump for liquids. At present, positive displacement pumps on the market can be roughly divided into two categories: reciprocating pumps and rotary pumps. [0003] Most of the existing reciprocating diaphragm pumps have the following defects. When the connecting rod is displaced in the horizontal direction under the action of the eccentric shaft, pure linear motion in the horizontal direction cannot be produced because the connecting rod is in a flexible connection state with the diaphragm and the oil seal. Since it is impossible to produce pure linear m...
