Problems solved by technology
The high-pressure stage lubrication of existing reciprocating compressors usually relies on a small amount of lubricating oil contained in the intake air of the high-pressure stage to lubricate between the cylinder and the piston, but because most of the lubricating oil exists in the gas, it cannot be well distributed in the cylinder wall, therefore less lubricated

Embodiment Construction
[0020] All the above-mentioned drawings constitute a part of the description, so that all the structures of the present invention can be understood more deeply, and the principles of the present invention are explained, and how the method achieves the purpose of lubricating the high-pressure stage of the reciprocating compressor.
[0021] The high-pressure stage lubrication method of the reciprocating compressor of the present invention is characterized in that it comprises the following steps:
[0022] First, an intercooler is connected between the low-pressure stage and the high-pressure stage of the reciprocating compressor. The suction valve and the exhaust valve are installed on the cylinder head of the high-pressure stage cylinder, and the air intake valve is installed on the intake passage from the suction valve seat to the cylinder. There are guide slots for rotating the intake air of the high pressure stage of the reciprocating compressor.
[0023] The oil-containing ...

The invention discloses a lubricant method at high pressure stage, used in recipocal compressor, comprising that: arranging middle cooler between low pressure stage and high pressure stage and connecting them; mounting adsorption valve and exhaust valve on the cylinder cover of high pressure stage cylinder; arranging guide groove that rotates the gas on the air inlet channel from adsorption valve to the cylinder; when gas and lubricant mixture flow through the low pressure stage compression and middle cooler, part of lubricant will be guided back to the low pressure stage and another part will be carried by gas to enter into high pressure stage; when the adsorption valve of high pressure stage is opened via pressure difference and the gas lubricant enters into cylinder via the adsorption valve, the gas will first flow in guide groove, and since the guide groove has rotation, the mixture of gas and lubricant will rotate when enters into cylinder, and the lubricant will be thrown out via eccentric force, to be separated from gas, to be splashed on the cylinder wall, to lubricant the cylinder and piston.
Description
technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a high-pressure stage lubrication method of a reciprocating compressor. Background technique [0002] The reciprocating compressor realizes the sequential and repeated process of suction, compression and exhaust through the opening and closing of the suction valve and the discharge valve. In order to obtain higher pressure gas, reciprocating compressors need to use multi-stage compression. In multi-stage compression, the stage with the lower exhaust pressure is called the low-pressure stage, and the stage with the higher exhaust pressure is called the high-pressure stage. [0003] High-pressure gas is widely used in power, shipping, refrigeration, storage and transportation and other fields or industries. The main device for obtaining high-pressure gas is a high-pressure compressor, and the reciprocating structure is the main structural type for obtaining high-pr...
