Abstract
The utility model comprises a compressed air cylinder for a diaphragm compressor. The compressed air cylinder for the diaphragm compressor comprises a cylinder body, a cylinder cover, an oil distribution disc and a membrane, wherein the cylinder body is provided with an accommodating cavity used for accommodating the cylinder cover, and the oil distribution disc is fixed at the bottom of the accommodating cavity. The cylinder cover is arranged inside the accommodating cavity of the cylinder body through a gland nut and is located at the upper portion of the oil distribution disc. The cavity surrounded by the cylinder cover and the oil distribution disc is a working chamber of the compressed air cylinder, and the membrane is arranged inside the working chamber and separates the working chamber into two independent parts. By means of increasing the cylinder body of the compressed air cylinder and fixing the cylinder cover in the cylinder body, the structure of the compressed air cylinder is more firm and compact, the effect is extremely prominent when carrying out high pressure and ultrahigh pressure compression, the sealing performance of the structure of the cylinder body is improved greatly so that working reliability of the diaphragm compressor is improved.
Description
Technical field
The utility model relates to a kind of diaphragm type compressor compression cylinder.
Background technique
Diaphragm type compressor is a kind of positive displacement compressor, as shown in Figure 1, existing diaphragm type compressor comprises: crankcase 1, crankshaft link rod motion mechanism 2 and compression cylinder, as shown in Figure 2, prior art septation compressor compresses cylinder is comprised of cylinder cap 3, diaphragm 5, oil distribution casing 6 and cylinder body 4 etc.Wherein, cylinder cap 3 is fixed on cylinder body 4 tops by some fixing bolts 7 that pass itself and cylinder body 4, and diaphragm 5 and oil distribution casing 6 are arranged in cylinder cap 3 and the active chamber that just cylinder body 4 has surrounded, and diaphragm 5 is divided into two-part with active chamber, wherein the space between diaphragm 5 and the cylinder cap 3 is air cavity, is used for holding gas; Space between diaphragm 5 and the cylinder body 4 is oil pocket, is used for holding working medium.Oil distribution casing 6 is arranged in the oil pocket, and is fixed on the cylinder body 4.During work, drive crankshaft link rod motion mechanism 2 motions that are arranged in crankcase 1 by external drive mechanism, and it is reciprocating to drive piston or plunger disposed thereon by it, and working medium (incompressible) is pushed in the oil pocket.During work, reduce the working medium in the oil pocket, gas to be compressed is drawn in the air cavity, after reaching preset vol, piston or plunger promote oil cylinder medium are input in the oil pocket, and drive motion of membrane, gas in the compression air cavity, and with its discharge diaphragm type compressor.Realized and so forth the purpose of gas compression.Although this compression cylinder can be finished the compression of gas, because cylinder cap and cylinder body are bolted, when the compression cylinder internal pressure is too high, leak easily, affect the work of film compressor.
The model utility content
Problem for the prior art existence, the purpose of this utility model is to provide a kind of diaphragm type compressor compression cylinder, this compression cylinder lengthens cylinder body, by cylinder cap is fixed in the cylinder body, make the structure between cylinder cap and the cylinder body more stable, can not cause owing to the pressure in the active chamber is excessive leakage.
For achieving the above object, a kind of diaphragm type compressor compression cylinder of the utility model comprises gray iron, oil distribution casing and diaphragm, and described cylinder body band is useful on the receiving cavity of accommodating cylinder lid, and described oil distribution casing is fixed on the bottom of described receiving cavity; Described cylinder cap is arranged in the receiving cavity of described cylinder body and is positioned at the top of oil distribution casing by gland nut, the cavity that described cylinder cap and described oil distribution casing surround is described compression cylinder active chamber, described diaphragm arrangement is in described active chamber, and be described compression cylinder active chamber with the cavity that active chamber divides described cylinder cap and described oil distribution casing to surround, described diaphragm arrangement and is divided into two independent sectors with active chamber in described active chamber.
Further, be provided with on the described receiving cavity sidewall for the screw thread of described gland nut engagement.
Further, also be provided with the screw that runs through described gland nut along its axial direction on the described gland nut.
Further, described compression cylinder also comprises hold-down bolt, and described hold-down bolt passes described screw, and leans on described cylinder cap.
This diaphragm type compressor compression cylinder disclosed in the utility model passes through to increase the compression cylinder cylinder body, and cylinder cap is fixed in the cylinder body, makes the structure of compression cylinder more firmly compact, and effect is particularly outstanding when carrying out the compression of high pressure or ultrahigh pressure.Improve greatly the sealability of housing structure, and then improved the functional reliability of diaphragm type compressor.
