Embodiment Construction

[0018] 1. Keep the inlet unobstructed, and install a hose and joint at the outlet of the valve seat 10, which can be used as a quick pump;

[0019] 2. Connect the pipeline at the inlet and feed the fluid to be sucked, and connect the corresponding pipeline and nozzle at the outlet, which can be used as a simple fire sprinkler, agricultural (household) sprayer, toy water gun, etc.;

[0020] 3. Equipped with corresponding manual or motorized devices, it can be used as a water pump and an oil pump.

[0021] In the specific implementation, there are the following three situations, which can be applied according to actual needs:

[0022] ①The pump body 5 is fixed, and the piston push-pull rod 3 moves telescopically;

[0023] ②The piston push-pull rod 3 is fixed, and the pump body 5 reciprocates;

[0024] ③Piston push-pull rod 3 and pump body 5 are not fixed.

[0025] The invention is an innovative breakthrough to the traditional fluid piston pump. The large-scale one can be used...

Abstract

The invention discloses a non-prepressing passive fluid piston pump with synchronous suction and discharge. When outside forces act on a push-pull rod of the piston 3 or a pump body 5 respectively or at the same time, and the piston 4 makes coaxial vertical and relative movement inside a pump cylinder 6, positive and negative pressure is produced on both sides of the piston 4 at the same time. An inlet column valve 7 and an outlet ball valve 11 are pressed simultaneously along with pressure conduction, and move axially from the direction of the positive pressure to the direction of the negative pressure inside the valve base. The liquid inside the pump cylinder 6 sprays towards the outlet due to the positive pressure. The negative pressure inside the pump cylinder 6 forms vacuum to suck the liquid outside the pump, so that the liquid piston pump can realize dual-stoke synchronous spray and suction.

Description

Technical field: [0001] The invention relates to a non-preloaded passive suction-discharge synchronous fluid piston pump, which belongs to the category of general mechanical structures. Background technique: [0002] The traditional non-preloaded passive fluid piston pump sprays or discharges after suction. It is a two-way reciprocating piston pump with one suction and one discharge. The general structure is more complex. Invention content: [0003] The purpose of the present invention is to realize the synchronous suction and discharge of the piston reciprocating double strokes, that is, to have the inlet suction force and the outlet expansion force that increase or decrease with the change of the external force, and the outlet can be ejected or discharged at the same time as the inlet suction and suction, so that the fluid piston The pump eliminates useless work and improves the suction and discharge efficiency of fluid piston pumps with the same bore and stroke in the ...
