Opposed diaphragm compression engine capable of auto-regulating coaxial degree of bar piston and plunger case

Abstract

The invention relates to opposed membrane compressor which can adjust the axiality of the pole cork and the cork cover automatically. It is mainly applied to compressing and transmitting purified air. It includes crank box, crank, sliding block, sliding cover and left and right working cylinders, the crank is arranged in the crank box, the sliding cover is arranged on the bellcrank of the crank, the sliding cover is covered out of the sliding block, the left and right working cylinders are separated into two parts with films 1-2, one is the oil cylinder, the other is a gas cylinder, the oil cylinder includes a cylinder, pole cork and cork cover, the cylinder is arranged on the lift and right sides of the crank box, the pole cork cover is embedded in the crank box and the cylinder, the pole cork is arranged in the cylinder and the pole cork cover, connected to the left and the right sides, the character is that the left and right sides of the sliding cover are arranged with slots, the connecting end of the pole cork and the sliding cover uses the ball head structure, the ball head structure is arranged in the slots, connected to the sliding cover. The axiality of the pole cork and the cork cover can be adjusted automatically; and reducing wear.

Description

Technical field: [0001] The present invention relates to a compressor. In particular, it relates to an opposed diaphragm compressor which can automatically adjust the coaxiality of the plunger and the plunger sleeve. It is mainly used for compressing and transporting purified gas. Background technique: [0002] At present, the existing opposed diaphragm compressor is mainly composed of crankcase, crankshaft, slider, sliding sleeve, left and right working cylinders, oil pump, suction and exhaust valves, gas pipeline system and oil pipeline system. The crankshaft is placed in the crankcase, the slider sleeve is placed on the crank throw of the crankshaft, and the slider sleeve is placed on the slider. The left and right working cylinders are divided into two parts by a diaphragm, one is an oil cylinder and the other is an air cylinder. The oil cylinder includes There are a cylinder block, a plunger and a plunger sleeve, the cylinder block is placed on the left and right side...

AI Technical Summary

Problems solved by technology

[0003] Since the two sides of the plunger and the sliding sleeve are fixedly connected by welding, the mating pair of the plunger and the plunger sleeve is affected by the machining accuracy of the parts, and the coaxiality is difficult to guarantee, so that the contact friction of the plunger and the plunger sleeve mating pair, Increased wear

And the installation space is large, so the crankcase can only adopt split structure
