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 which is arranged on the cylinder body, and a membrane which is arranged between the cylinder body and the cylinder cover and separates a cavity between the cylinder body and the cylinder cover into two parts. The compressed air cylinder for the diaphragm compressor further comprises a plurality of units of sealing element used for sealing the buckle place of the cylinder body and the cylinder cover. By means of the plurality of units of the sealing element are arranged on the buckle place of the cylinder body and cylinder cover and the sealing of the compressed air cylinder, the airtight efficiency of the compressed air cylinder can be effectively ensured, the renewal frequency of a sealing ring can be reduced, and the production efficiency and the service life of the compressed air cylinder can be improved.
Description
Technical field
The utility model relates to a kind of compression cylinder that is applied to diaphragm type compressor.
Background technique
Diaphragm type compressor is a kind of positive displacement compressor, its structure as shown in Figure 1, specifically comprise: crankcase 1, crankshaft link rod motion mechanism 2 and compression cylinder, compression cylinder comprises cylinder cap 3, cylinder body 4 and diaphragm 5, wherein cylinder cap 3 is arranged on cylinder body 4 tops, diaphragm 5 is arranged between cylinder cap 3 and the cylinder body 4, and 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.During work, driven 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 the working medium (incompressible) that piston or plunger promote in the oil cylinder (not shown) enters into oil pocket.When the medium in the oil pocket reduced gradually, gas to be compressed entered into air cavity, reach preset vol after, piston or plunger promote oil cylinder medium are input in the oil pocket, and drive motion of membrane, the gas in the compression air cavity, and it is discharged diaphragm type compressor.Realized and so forth the purpose of gas compression.
Because above-mentioned diaphragm type compressor has compressed media and is not polluted, and have that good heat dissipation potential namely contains cylinder area and its volume ratio is larger, perfect heat-dissipating, compression process are near advantages such as isothermal compression, and diaphragm type compressor is widely used in all trades and professions.But as shown in Figure 1, usually only by seal ring 6 sealings, not only sealing effect is poor between cylinder cap for the compression cylinder cylinder body 4 of diaphragm type compressor, in case and seal ring 6 damage, compression cylinder will occur to leak and can't continue to use.Can only with cylinder cap 3 by pulling down on the cylinder body 4, change seal ring 6.The compression cylinder manufacturing efficiency of this structure is low, and maintenance cost is higher.
The model utility content
Problem for the prior art existence, a kind of diaphragm type compressor compression cylinder of the utility model, by between diaphragm type compressor compression cylinder cylinder block and cylinder cover, new type sealing element being set, between forms labyrinth seal structure, the realization of compression cylinder is better sealed, and sealing structure long service life, thus diaphragm type compressor normal operation requirement guaranteed, improve the manufacturing efficiency of diaphragm type compressor.
For achieving the above object, a kind of diaphragm type compressor compression cylinder of the utility model comprise cylinder body, be arranged on the cylinder cap on the cylinder body and be arranged on described cylinder body and described cylinder cap between, cavity between the described cylinder block and cylinder cover is separated into two-part diaphragm, also comprises the many groups Sealing be used to the fastening place that seals described cylinder body and described cylinder cap.
Further, every group of described Sealing include be arranged on the cylinder cap lower surface and be positioned at described fastening place groove upper seal ring and be arranged on described cylinder body upper surface and be positioned at the lower seal of described fastening place groove.
Further, each is organized described seal ring and arranges with one heart.
A kind of diaphragm type compressor compression cylinder of the utility model, by the fastening place at the cylinder cap of compression cylinder and cylinder body some groups of seal rings being set seals compression cylinder, can effectively guarantee the airtight effect of compression cylinder, and reduce the replacement frequency of seal ring, enhance productivity and working life of compression cylinder.

Embodiment
As shown in Figure 2, the compression cylinder of the utility model diaphragm type compressor comprises cylinder body 4, is arranged on the cylinder cap 3 on the cylinder body 4, also is provided with diaphragm 5 between cylinder cap 3 and cylinder body 4, diaphragm 5 is divided into two parts with formed cavity between cylinder cap 3 and the cylinder body 4, is respectively air cavity 6 and oil pocket 7.Cylinder cap 3 also is provided with for the many group Sealing of the cavity that cylinder cap 3 and cylinder body 4 are surrounded with extraneous sealing with the fastening place of cylinder body 4, every group of Sealing is and is separately positioned on cylinder cap 3 lower surfaces, and be positioned at the upper seal ring 8 of the groove at the fastening place that joins with cylinder body 4, and be positioned at cylinder body 4 upper surfaces and be in lower seal 9 with the groove at cylinder cap 3 fastening places; Preferably, each is organized Sealing and arranges with one heart.
Claims (3)
1. diaphragm type compressor compression cylinder, it is characterized in that, described diaphragm type compressor compression cylinder comprise cylinder body, be arranged on the cylinder cap on the cylinder body and be arranged on described cylinder body and described cylinder cap between, cavity between the described cylinder block and cylinder cover is separated into two-part diaphragm, also comprises the many groups Sealing be used to the fastening place that seals described cylinder body and described cylinder cap.
2. described diaphragm type compressor compression cylinder according to claim 1, it is characterized in that, every group of described Sealing include be arranged on the cylinder cap lower surface and be positioned at described fastening place groove upper seal ring and be arranged on described cylinder body upper surface and be positioned at the lower seal of described fastening place groove.
