Problems solved by technology

If the double plunger one-way constant flow pump is used to pump alternately, a stable and constant flow can be achieved. However, in the dynamic constant pressure flow reaction system, there are often multiple independent liquid outlet channels that require constant flow. At this time, it must be arranged at each independent channel. A set of dual plunger constant flow pumps, resulting in a cumbersome flow system and a huge investment in experiments

Abstract

The invention discloses a constant flow pump device, which comprises a plunger barrel, a plunger reciprocating in the plunger barrel, the plunger divides the plunger barrel into a sealed first chamber and a second chamber, and respectively The first reversing valve and the second reversing valve connected to the first chamber and the second chamber. Wherein, after the first reversing valve and the second reversing valve are connected in parallel, one end communicates with the external liquid inlet, and the other end communicates with the external liquid outlet. The invention can realize bidirectional continuous constant current, and can also realize bidirectional continuous constant current for multiple channels in a dynamic constant pressure flow system.

Description

technical field [0001] The invention belongs to the field of mechanical power and relates to a constant flow pump device. Background technique [0002] The constant flow pump device is a commonly used mechanical device in the liquid material conveying system, and different systems have different requirements for the constant flow pump device. The existing constant flow pump plunger cylinders are all one-way half-cycle constant flow, that is, constant flow when the plunger advances at a constant speed, and when the plunger is pushed to the limit, the constant flow stops, and the plunger needs to retreat to the starting position before restarting the constant flow. flow. At the same time, in order to realize continuous constant flow, the existing constant flow pump uses two plungers to alternately perform unidirectional constant flow operation. [0003] In the dynamic constant pressure flow reaction system, fresh liquid is continuously input. In order to keep the pressure in...
