Abstract

The utility model relates to an integral crankcase opposed diaphragm compressor, which is chiefly used for decompressing and conveying the purified gas. The integral crankcase opposed diaphragm compressor contains a crank case 2, a crank shaft 3, a slider 4, a sliding sleeve 5 and a left working cylinder and a right working cylinder 1; the crank shaft is arranged in the crank case; the slider is covered on the crank of the crank shaft; the sliding sleeve is covered on the slider; the left working cylinder and the right working cylinder are separated into two parts by membranes 1-2; one is an oil cylinder, and the other is an air cylinder; the oil cylinder contains a cylinder body, a plunger and a plunger sleeve; the cylinder bodies are arranged on the left side and the right side of the crank case; the plunger sleeve is embedded in the case wall of the crank case and the cylinder body; the plungers are arranged in the cylinder body and the plunger sleeve, and are connected with the left side and the right side of the sliding sleeve. The features of the integral crankcase opposed diaphragm compressor are that: the crank case 2 adopts the integrative structure; in this way, the connection component of the oil circuit can be caused to obtain the omission; the leakage is reduced in the operating condition; the structure of the complete machine is compact and the exterior is compact and beautiful.

Description

Barrel type crankcase opposed type diaphragm type compressor

Technical field:

The utility model relates to a kind of compressor.Especially relate to a kind of barrel type crankcase opposed type diaphragm type compressor.Be mainly used in compression, delivery of purge gas.

Background technique:

Present existing opposed type diaphragm type compressor mainly is made up of crankcase, bent axle, slide block, sliding sleeve, left and right clutch release slave cylinder, oil pump, suction, outlet valve and air pipe system and oil pipe line system etc.Bent axle places in the crankcase, slide block set places on the crankshaft crank, sliding sleeve is placed on the slide block, left and right clutch release slave cylinder is separated into two parts with diaphragm, one is oil cylinder, another is cylinder, oil cylinder includes cylinder body, plunger and plunger bushing, cylinder body places the crankcase left and right sides, plunger bushing is embedded in crankcase tank wall and the cylinder body, plunger places in cylinder body and the plunger bushing, links to each other with the sliding sleeve left and right sides, and plunger is done straight reciprocating motion in cylinder block, realizing compression process, and then finish compression to gas to diaphragm.

It mainly has the following disadvantages:

Because crankcase adopts split-type structural, makes that the oil circuit connector element is more, external form is mixed and disorderly, complete machine structure is loaded down with trivial details, and the leakage under the operating mode is more.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned deficiency, provides the leakage under a kind of operating mode less barrel type crankcase opposed type diaphragm type compressor.

The purpose of this utility model is achieved in that a kind of barrel type crankcase opposed type diaphragm type compressor, comprise crankcase, bent axle, slide block, a sliding sleeve and a left side, right clutch release slave cylinder, bent axle places in the crankcase, slide block set places on the crankshaft crank, sliding sleeve is placed on the slide block, a left side, right clutch release slave cylinder is separated into two parts with diaphragm, one is oil cylinder, another is a cylinder, oil cylinder includes cylinder body, plunger and plunger bushing, cylinder body places a crankcase left side, right side, plunger bushing are embedded in crankcase tank wall and the cylinder body, and plunger places in cylinder body and the plunger bushing, with a sliding sleeve left side, the right side links to each other, be characterized in: crankcase adopts monolithic construction, like this can be so that the oil circuit connector element obtain omitting, and the leakage under the operating mode reduces, complete machine structure is simple and direct, and external form is succinctly attractive in appearance.

Embodiment:

As Fig. 1～2, the utility model is a kind of barrel type crankcase opposed type diaphragm type compressor, mainly is made up of crankcase 2, bent axle 3, slide block 4, sliding sleeve 5, left and right clutch release slave cylinder 1, oil pump 7, slippage pump 6, flywheel 8, suction, outlet valve 9,10 and air pipe system and oil pipe line system etc.Bent axle 3 places in the crankcase 2.In the slide block 4 axis hole is housed, is upper and lower two valve structures, be placed on the bent axle 3 crank throw 3-1 with 4 bolts connections and by bearing shell, sliding sleeve 5 is placed on the slide block 4.Clutch release slave cylinder 1 usefulness diaphragm 1-2 is separated into two parts, and one is oil cylinder 1-3, another is cylinder 1-1, and oil cylinder 1-3 includes cylinder body 1-3-2, plunger 1-3-1 and plunger bushing 1-3-3.Cylinder body 1-3-2 places crankcase 2 left and right sides, and plunger bushing 1-3-3 is embedded in crankcase 2 tank walls and the cylinder body 1-3-2, and plunger 1-3-1 places in cylinder body 1-3-2 and the plunger bushing 1-3-3, links to each other with sliding sleeve 5 left and right sides.

As Fig. 3～8, crankcase 2 adopts monolithic construction.
