The displacement of the compressor should take into account the gas cycle, gas consumption, possible leakage of the pipeline, future expansion plan and other factors, generally should be about 20% more than the actual consumption.
The displacement of the compressor should take into account the gas cycle, gas consumption, possible leakage of the pipeline, future expansion plan and other factors, generally should be about 20% more than the actual consumption. The main reasons for the high temperature can be divided into the following: oil filter blockage, temperature control valve spool jam, oil cooler internal or external is seriously polluted.
Oil filter installed in the temperature control valve and oil cooler upstream is an effective way to avoid oil failure, but many brands of screw compressor oil filter only to protect the head. The intake and exhaust processes in the air compressor are similar to the oil suction and oil pressure processes of the hydraulic pump. A piston machine of this construction always has a residual volume at the end of the venting process. During the next inhalation, the compressed air in the remaining volume will expand, thereby reducing the amount of air inhaled, reducing efficiency and increasing compression work.
Piston Machine Company's full range of commercial HVAC equipment has almost achieved the upgrading of a new generation of refrigerants. Mechanism, there is an unavoidable inertial force, so the vibration is large during operation, the noise is high, and the larger piston air compressor needs a special fixed foundation when installing. The screw air compressor is a rotary motion mechanism with good balance, low vibration, low noise, no need to install the foundation, and also avoids the pollution of the working environment.
The types of models used are too many and too scattered, which is not convenient for equipment management, but also increases the number of wearing parts, which is bound to increase the cost of normal operation. The piston continues to move upward, causing the gas pressure in the cylinder to be greater than the exhaust pressure, the exhaust valve opens, and the gas in the cylinder is pushed out of the cylinder and enters the exhaust pipe at equal pressure until the piston moves to the top dead center. At this time due to the exhaust valve spring force and the valve itself gravity, the exhaust valve closed exhaust end.
