Abstract

The invention discloses a single-stage multi-head diaphragm type gas pump, which comprises a main shaft, wherein four connecting rods are arranged on the main shaft; two ends of the main shaft are connected with one end of each connecting rod through eccentric wheels respectively; bearings are arranged among the eccentric wheels and the connecting rods; a diaphragm bearing plate is arranged at the other end of each connecting rod, the connecting rods are connected with valve block pressure plates fixedly through diaphragm bearing plates, and diaphragms are fixedly arranged among the valve block pressure plates and the diaphragm bearing plates; valve covers are arranged above the diaphragms, the valve covers and the peripheries of the diaphragms are fixedly arranged inside a gap between a cylinder cover and a cylinder body, and the cylinder cover and the cylinder body form a gas cylinder; gas inlet valve blocks are arranged on the valve covers; the cylinder body is movably connected with the main shaft through another bearing; and the cylinder body is fixedly connected with a fan blade shield base, the fan blade shield base is connected with one ends of fan blades, and the other end of the fan blades are fixedly connected with the fan blade shield. The gas pump has the advantages that the size is small, the weight is light, the pump can be carried conveniently, energy is saved, the efficiency is high, and the like. The gas pump is an ideal device which can be matched with a spray gun for spray painting operation.

Description

technical field [0001] The invention relates to a mechanical pump, in particular to a single-stage multi-head diaphragm air pump. Background technique [0002] The diaphragm air pump is a reciprocating pump that relies on the diaphragm to reciprocate in the cylinder to compress and deliver gas. The diaphragm is clamped by two limiting plates along the periphery and is movably set in the cylinder. The diaphragm is driven by mechanical or hydraulic pressure to reciprocate in the cylinder, so as to realize the compression and delivery of gas. The diaphragm of the diaphragm air pump is generally made of rubber or plastic and is driven mechanically or hydraulically. It is only suitable for occasions with a displacement of several cubic meters per hour and an exhaust pressure of about 1.2 MPa. Generally, it is single-stage or two-stage. . [0003] The main shaft of the existing single-stage single-cylinder diaphragm pump rotates one revolution, and can only complete compression ...
