Energy-saving type variable displacement pump

Abstract

The invention discloses an energy-saving type variable displacement pump, relates to the technical field of mechanical conveying, and solves the problems that a variable displacement pump used at present is too large in size, irregular in shape and appearance, inconvenient to combine and use in multiple groups, not beneficial to unifying functions on a large scale and poor in energy-saving effect. The energy-saving type variable displacement pump comprises a connecting set, a gear ring and power plates; a main body of the connecting set is of a strip-shaped structure, two sets of pump bins are fixedly arranged at the two sides of the connecting set, and the bottom faces of the pump bins are flush with the bottom face of the connecting set; an annular groove is formed in the middle of the edge of the gear ring; and the two sets of power plates are arranged, and two sets of side frames are fixedly arranged at the two sides of the middles of the two sets of power plates. The pump bins are arranged, the appearance of the variable displacement pump is set to be in a regular shape, splicing and combination use is facilitated, unified control can be achieved, the working efficiency is improved, the energy-saving effect is good, and no space is occupied.

Description

technical field [0001] The invention relates to the technical field of mechanical transportation, in particular to an energy-saving variable capacity pump. Background technique [0002] A pump is a machine that transports fluid or pressurizes the fluid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. The main working principle of the common variable displacement pump is to change the internal pressure of the pump body. The conversion of negative pressure transports materials. [0003] After retrieval, for example, a patent with application number CN201680020383.6 discloses a variable capacity oil pump, which has: an electromagnetic switching valve, which is formed to be able to control the state of discharging the working oil from the second control oil chamber and the state of discharging the oil to the second control oil chamber. The state of introducing working oil is switched; the pilot v...

Problems solved by technology

[0009] The purpose of the present invention is to provide an energy-saving variable capacity pump to solve the first problem mentioned in the above background technology. The volume of the variable capacity pumps currently used is too large, the shape is irregular, and it is inconvenient to use multiple groups in combination, which is not conducive to Unified functions in large quantities, poor energy-saving effect, and insufficient work efficiency; second, the existing variable-capacity pumps do not have a convenient delivery volume synchronization adjustment device, and cannot simultaneously adjust the delivery volumes of two sets of pump chambers; third, they do not have stable The assembly structure is not conducive to the precise positioning of the transmission parts
