Abstract

The invention relates to the manufacturing field of electrical equipment, in particular to the manufacturing field of compressors, and specifically provides a motor direct driven diaphragm compressor. The motor direct driven diaphragm compressor is composed of a motor, a coupler, a compressor airplane and a crankshaft box. A motor shaft of the motor is connected to one end of the coupler, and the other end of the coupler is connected to the compressor airplane through a flange. A crankshaft connecting rod system in the crankshaft box is connected with the compressor airplane through a key joint. The axis of the motor, the axis of the coupler, the axis of the compressor airplane and the axis of the crankshaft box are located on the same straight line. According to the motor direct driven diaphragm compressor, the loss of intermediate transmission energy is reduced, the transmission efficiency is high, the reserve capacity is large, and the compressor saves more energy; during running, the vibration and impact resistance of the compressor is small, and the compressor can also normally work in a relatively hostile working condition environment; and the number of equipment accessories connected by an ordinary belt is reduced, the intermediate links of the compressor are reduced, the probability of failures is reduced, and the running cost and the maintenance cost are reduced.

Description

technical field [0001] The invention relates to the field of electrical equipment manufacturing, in particular to the field of compressor manufacturing, in particular to a diaphragm compressor directly driven by a motor. Background technique [0002] Diaphragm compressor is a volumetric compressor with a special structure, which has the characteristics of large compression ratio, good sealing, and the compressed gas is not polluted by lubricating oil and other solid impurities. Generally, a diaphragm compressor is mainly composed of a drive mechanism, crankcase components, crankshaft connecting rod piston components, cylinder components, lubricating oil system, gas pipeline components, etc. Under normal circumstances, the diaphragm compressor generally transmits the torque to the crankshaft through the large and small pulleys and the belt deceleration by the rotating motor, and then converts the rotary motion into reciprocating motion through the crank linkage mechanism in t...
