Embodiment Construction

[0018] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0019] Such as figure 1 Shown is a schematic view of the structure of the present invention, the present invention is a positive displacement pump with a cam mechanism, including a positive displacement pump body and a cam mechanism.

[0020] The slide valve positive displacement pump body includes a pump body 1, a spherical guide rail 2, a slide rod 3, a rotating main shaft 4, a main valve core 5 and an auxiliary valve core 6. It is characterized in that: the top of the pump body 1 has a water inlet 7, a There is a water outlet 8 on the side, and a pump chamber inside; the pump chamber is installed in turn from top to bottom, the upper valve chamber and the lowe...

Abstract

The invention provides a slide valve type volume pump with a cam mechanism. The slide valve type volume pump with the cam mechanism comprises a slide valve type volume pump body and the cam mechanism;the slide valve type volume pump body comprises a pump body, a spherical guide rail, a slide rod, a rotating main shaft, a main valve element and secondary valve elements; the cam mechanism comprisesa cam, a transmission gear, a transmission motor, a fixed rod, a connecting rod and an adjusting handle. The slide valve type volume pump with the cam mechanism is novel in structure, proper in production and installation cost and suitable for wide popularization and application, and can change the volume of a lower valve cavity through movement of the secondary valve elements at the two ends ofthe main valve element to guarantee the pumping efficiency and to guarantee the fluid conveying stability.

Description

technical field [0001] The invention belongs to the field of pumps and valves, in particular to a slide valve type displacement pump with a cam mechanism. Background technique [0002] A positive displacement pump refers to a pump that uses changes in the volume of the pump cylinder to transport liquids, such as reciprocating pumps, rotor pumps, and screw pumps. The existing volumetric pumps all have the defects of complex structure, large volume and low rotational speed, and the efficiency of pumping fluid is low in the current volumetric pumps introduced. [0003] Therefore, in view of the above problems, it is a difficult problem that those skilled in the art urgently need to solve to develop a new type of positive displacement pump that can ensure the efficiency of pumping fluid. Contents of the invention [0004] In order to solve the above problems, the present invention discloses a slide valve type positive displacement pump with a cam mechanism. [0005] In order...
