Novel buffering device for plunger pump

Abstract

The invention discloses a novel buffering device for a plunger pump, and belongs to the technical field of hydraulic equipment. The novel buffering device for the plunger pump comprises a ball body, a front tapered pipe and a rear tapered pipe; openings of the tapered pipes respectively pass through the ball body in opposite directions to form an inlet and an outlet; a cutting opening is formed in the middle of the tapered pipe; the cutting opening above the inlet is in a vertical angle, and the angle of the cutting opening above the outlet inclines toward the inlet; when in work, liquid flows into the tapered pipes through the inlet; when the tapered pipes are full of the liquid, the liquid flows into the wall body through the inlet cutting openings in four sides of the tapered pipes; when the wall body is full of the liquid, the liquid flows into the outlet tapered pipe through the outlet cutting incision and then flows out. The novel buffering device for the plunger pump is simple in structure and reasonable in design; the flowing speed and direction of the liquid are changed through the combination of the tapered pipes and the ball body, and thus the problem of non-uniform flow rate and speed of the liquid can be solved; the impact pressure and speed are reduced to some extent; the function of effective buffering is reached; the pulsing phenomenon is removed; the service life of the device is prolonged; the potential risk is removed.

Description

technical field [0001] The invention relates to the technical field of hydraulic equipment, in particular to a novel plunger pump buffer device. Background technique [0002] Piston pumps are compact in structure, small in size, small in size, light in weight, have high volumetric efficiency and total efficiency, and can work under high-speed rotation and pressure, so they are widely used in hydraulic equipment. Due to the structure of the plunger pump, the flow generated by it is periodic, which causes periodic pulsation of the hydraulic system. At present, the plunger pumps used in hydraulic systems generally adopt reciprocating plunger pumps, the outlet pressure is very high, and the high-pressure water flow has a large impact on outlet pipelines, valves, instruments and other facilities, causing pump vibration to exceed the limit and affecting the service life of the equipment. There are even greater security risks. [0003] In order to well solve the above problems, t...
