Embodiment Construction

[0055] like figure 1 , figure 2 , image 3As shown, a fluid pump driven by compressed air includes a central body 16, a central shaft 5, a reversing shaft 4, a left diaphragm 17, a right diaphragm 3, a left air chamber 14, a right air chamber 8, and a left fluid chamber 15. Right fluid chamber 7, valve ball A18, valve ball B2, valve ball C12, valve ball D10, fluid inlet 11 and flow out 19, etc. The central shaft 5 and the reversing shaft 4 are movably installed on the central body 16, and a sealing ring is installed between the central shaft 5, the reversing shaft 4 and the central body 16, and the central shaft 5 and the reversing shaft 4 move left and right on the central body 16 air will not pass through. The left diaphragm 17 and the right diaphragm 3 are respectively installed at both ends of the central shaft 5, and the two diaphragms are fixed on both ends of the central shaft 5 through the diaphragm splint 6, and the two ends of the reversing shaft 4 are also respe...

Abstract

A fluid pump driven by compressed air comprises a central body, a central shaft, a reversing shaft, membranes, air chambers, fluid chambers, a valve ball, a fluid inlet, a fluid outlet, etc. The central shaft and the reversing shaft are installed on the central body; a membrane is respectively installed at the two ends of the central shaft; the membranes are fixed at the two ends of the central shaft by membrane splints; and the two ends of the reversing shaft are also respectively connected on a left membrane splint and a right membrane splint. The membranes are clamped between a shell and a pump body; and the two membranes are sealed into a left air chamber, a right air chamber, a left fluid chamber and a right fluid chamber between the shell and the pump body; the reversing shaft controls the horizontal movement of a piston and respectively charges the two air chambers, and pushes and presses the fluid chambers by the membranes to lead the fluid to flow from the fluid inlet into the fluid chambers and then out of the fluid outlet. As the fluid pump which is driven by compressed air is provided with the reversing shaft, the movement of the piston is directly controlled by the compressed air but does not fail, and the maintenance and installation are convenient.

Description

technical field [0001] The invention relates to a fluid pump, especially a fluid pump driven by compressed air. Background technique [0002] Pneumatic fluid pumps are fluid delivery pumps powered by compressed air. The main structure of pneumatic fluid pumps includes air valves, diaphragms, central shafts, housings, valve balls, fluid inlets, and fluid outlets. The central shaft can slide left and right on the central body, and a diaphragm is installed at both ends of the central shaft. The diaphragm is fixed in the casing, and the two diaphragms are sealed in the casing to form two left and right air chambers and two left and right fluid chambers. The left and right air chambers supply and exhaust air alternately under the action of the air valve. When the air valve supplies air to the left air chamber, the left diaphragm expands outwards and pushes the left fluid chamber, and the fluid in the left fluid chamber pushes up. The valve opening ball is output from the outlet,...
