Oil storage piston pin for reciprocating type compressor capable of realizing starting lubrication convenience

Abstract

The invention discloses an oil storage piston pin for a reciprocating type compressor capable of realizing starting lubrication convenience, and is used in the field of the reciprocating type compressor. The oil storage piston pin comprises a pin body, wherein the upper end of the pin body is provided with an oil storage structure, and the lower end of the pin body is provided with a positioning pin installing side hole. In the oil storage piston pin for the reciprocating type compressor capable of realizing the starting lubrication convenience, the oil storage structure is arranged on the upper end surface of the piston plug and is used for collecting lubricating oil remained on a moving component. When the compressor is started in a next time, the lubricating oil in the oil storage structure is thrown out under the effect of inertia force, so a friction pair of a piston and an air cylinder hole can be lubricated. Therefore, the lubricating effect can be preferably realized in the starting moment of the compressor. The piston is protected from being abraded, and the starting moment is reduced.

Description

Technical field [0001] The invention is used in the field of reciprocating compressors, and particularly relates to a reciprocating compressor oil storage piston pin which is convenient to start and lubricate. Background technique [0002] Such as figure 1 , figure 2 As shown, the upper end of the traditional piston pin 6 is provided with a positioning pin mounting side hole 3. When in use, the connecting rod 46 forms a rotating connection pair with the piston 45 through the piston pin 6 and the piston pin 6 is connected to the piston 45 through the elastic positioning pin 47 Fixed connection. After the reciprocating compressor is started, the rotor drives the crankshaft 40 to start high-speed rotation. Relying on the driving force generated by the high-speed rotation, the lubricating oil passes through the oil hole 42 and the spiral oil groove 43 on the crankshaft 40 through the oil pump 41 at the lower end of the crankshaft 40 and reaches the crankshaft eccentricity. The oil ...

Problems solved by technology

[0003] First of all, due to the lack of lubrication, the reciprocating compressor has a large starting friction resistance, which requires a large starting torque of the compressor motor, high motor cost and low efficiency; secondly, the piston is in a dry friction state, with large friction resistance and serious wear, which is not conducive to improving the performance of the compressor. Compressor performance and service life of the protection compressor
