Composition of piston compressor

Transmission mechanism: it is composed of crank connecting rod mechanism, crosshead, slide, etc; 2. Working parts: cylinder, air valve, piston assembly, packing, etc; 3. Engine body: composed of crankcase and middle body; Cooling system: composed of water pump, oil cooler, etc;

Lubrication system: it is composed of fuselage lubrication system and cylinder packing lubrication system.

The price of twin-screw air compressor is about thousands of yuan per piece, and tens of thousands of yuan are expensive. The price of twin-screw air compressor is affected by many aspects, such as brand, category, specification, market, etc. Before choosing to buy, understanding and comparing in many ways is View full text

Working principle of piston compressor

The engine drives the compressor crankshaft to rotate through the elastic coupling, so as to drive the connecting rod to move, and the rod body swings. The small end of the connecting rod drives the prefix, piston rod and piston to move back and forth. When the piston moves to the left, the right working volume increases, the pressure in the cylinder decreases, forming a local vacuum, and the process gas overcomes the resistance of the inlet valve and enters the cylinder, The exhaust valve closes under the action of spring force. At the same time, the left working volume gas is compressed. When the piston runs at the inner dead center, the suction of the right working volume stops, and the compressed gas in the left working volume overcomes the resistance of the exhaust valve and discharges the cylinder. When the piston runs to the right, it is opposite to the above process, so as to increase the gas pressure and complete the working cycle from suction → compression → exhaust.
