Abstract
The utility model discloses a compressed air cylinder cover of a separating film compressor. The compressed air cylinder cover of the separating film compressor comprises a cylinder cover body and a plurality of liquor drainage holes. The liquor drainage holes are communicated with an air cavity formed by the cylinder cover and film pieces and the liquor drainage holes are arranged in the cylinder cover body. According to the compressed air cylinder cover of the separating film compressor, the liquor drainage holes used for discharging residual liquid is arranged in the cylinder cover, thus the separating film compressor which can be suitable for compressing dry gas can be used for liquid or compression and delivery of the gas carrying the liquid. The application range of the separating film compressor is broadened. The compressed air cylinder cover of the separating film compressor is convenient to machine and maintain. Reliability of the separating film compressor is improved.
Description
Technical field
The utility model relates to a kind of compression cylinder cylinder cap 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 the compression cylinder area and its volume ratio is larger, perfect heat-dissipating, compression process is near isothermal compression) etc. advantage, diaphragm type compressor is widely used in all trades and professions, but diaphragm type compressor usually can not be used for compression and carry liquid, can only compress and carry gas, and along with the extensive use of diaphragm type compressor, the compression of part customer demand and conveying are with the gas of Micro-volume liquid or the liquid of separating out in the compression cooling procedure, like this, existing diaphragm type compressor is because its structural limitations, can't satisfy the demand of carrying liquid etc.
The model utility content
Problem for the prior art existence, a kind of diaphragm type compressor compression cylinder of the utility model cylinder cap, the purpose of discharging by at diaphragm type compressor compression cylinder cylinder cap outage being set, can reaching the residual liquid that allows in the compression cylinder, thus diaphragm type compressor normal operation requirement guaranteed.
For achieving the above object, a kind of diaphragm type compressor compression cylinder of the utility model cylinder cap comprises the cylinder cap body, and is arranged on the some outages on the cylinder cap body, and outage and described cylinder cap are connected with air cavity between the diaphragm.
Further, described outage is through hole on the same circumference that is distributed in the described compression cylinder cylinder cap.
Further, the axis of described outage parallels with the axis of described compression cylinder cylinder cap.
Further, described outage is positioned at the port at cylinder cap top with the connection set that is connected with external pipe.
Further, described connection set is the screw thread that is arranged on the described outage sidewall.
A kind of diaphragm type compressor compression cylinder of the utility model cylinder cap, by being provided with at cylinder cap for the outage of discharging residual liquid in the air cavity, can making the diaphragm type compressor that is only applicable to compression drying gas in the prior art also can be used in liquid or carry compression and the conveying of the gas of liquid.Drawn together greatly the application area of diaphragm type compressor, processing and easy to maintenance has improved the reliability of diaphragm type compressor.
Description of drawings
Fig. 1 is prior art septation compressor arrangement schematic representation;
Fig. 2 is the compression cylinder structural representation of the utility model diaphragm type compressor;
Embodiment
As shown in Figure 2, the utility model diaphragm type compressor cylinder cap 3 is arranged on the cylinder body 4, also is provided with diaphragm 5 between cylinder cap 3 and cylinder body 4, and diaphragm 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 comprises cylinder cap body and the some outages 8 that are arranged on the cylinder cap body, outage 8 is used for air cavity 7 is connected with the external world, and is for being arranged on the through hole on the cylinder cap body, preferred, on some outage 8 uniform same circumference, and the axis of each outage 8 is parallel with the cylinder cap body axis.Outage 8 is positioned at the port at cylinder cap top with the connection set that is connected with external pipe, and this connection set can be the screw thread on the sidewall that is arranged on outage 8.
During work, the use cylinder cap is carried liquid with the diaphragm type compressor of outage or is carried the gas of liquid, as when finding that residual liquid is too much in the air cavity, then can open with outside Drainage pipe that outage 8 is connected on valve, liquid in the air cavity is discharged, and diaphragm type compressor can recover normal operation.
Diaphragm type compressor in the utility model makes diaphragm type compressor applicable to transport liquid and the gas that carries liquid by be provided for discharging the outage of residual liquid in the air cavity at cylinder cap, makes its application area more extensive.
