Example 2:
a diaphragm compressor is a special type of volumetric compressor. The motor is used as a driving force, a crankshaft of the diaphragm compressor is driven to rotate through a belt or a coupling, the crankshaft rotates to drive a connecting rod arranged on a crank throw of the crankshaft to do plane motion, so that a crosshead and a piston arranged at the small end of the connecting rod are driven to do reciprocating linear motion, the motion amplitude is equal to 2 times of the radius of the crank throw of the crankshaft, namely 1 stroke, and the motion frequency is the rotation frequency of the crankshaft.
As shown in fig. 3, the position of the piston at the top dead center is used as the starting point, when the crankshaft rotates, the piston starts to move downwards, the diaphragm gradually deforms towards the oil distribution disc along with the flowing of hydraulic oil and the action of self elasticity, the volume of the air cavity gradually increases, the gas remained in the clearance expands firstly, then the gas is sucked from the suction valve of the air cavity, and when the piston moves to the bottom dead center, the diaphragm reaches the limit position at the lower end, and then the suction process in the air cavity is completed.
Then, the piston starts to move upwards to drive hydraulic oil to flow, a plurality of small holes on the oil distribution disc uniformly act on the diaphragm to push the diaphragm to deform upwards, at the moment, gas is compressed in the air cavity, when the pressure is higher than the gas pressure in the exhaust pipeline, the exhaust valve is automatically opened, the gas is extruded out, the piston continues to move upwards to force the diaphragm to be tightly attached to the curved surface of the cylinder cover, the gas is exhausted, and the exhaust process is finished.
The reciprocating piston drives hydraulic oil to make the diaphragm vibrate back and forth, and the circular process including expansion, air suction, compression and exhaust is completed once in the cylinder every time the diaphragm vibrates for one period under the cooperation of the air suction valve and the exhaust valve, so that the pressure of the conveyed gas is increased.
The compressor is provided with a compensation oil pump, the compensation oil pump injects oil into the oil cylinder in the suction stroke, the oil quantity is slightly more than the leakage quantity, and the more oil quantity flows back to the crankcase through a pressure regulating valve or a follow-up valve for controlling the oil pressure under the set pressure.
The air cavity and the oil cavity are completely separated by the diaphragm, the diaphragm reciprocates to play a role of a piston, so that no lubricating substance is required to be added into the air cavity, the compressed medium only contacts with the metal diaphragm and can not be polluted completely, the purity of the compressed medium is ensured, the air cavity consists of the curved surface of the cylinder cover and the diaphragm, and the air cavity is a closed cavity and has excellent sealing performance. Therefore, the diaphragm compressor can compress gas with extremely high purity, and the purity of the gas can reach 99.999 percent generally.
