In order to ensure that the compressor is in a good state of operation and extend the service life of the machine, maintenance must be performed. Through maintenance, you can fully grasp the status of the machine, you can find problems in a timely manner, troubleshooting, improve the working conditions of the machine, even if you view the fault, but also easy to judge and take measures. Next Xiaobian introduced the features of the piston compressor and the routine maintenance of the piston compressor.
Piston compressor features
1. The applicable pressure range is wide, and the required pressure can be achieved regardless of the flow rate;
2, high thermal efficiency, unit power consumption;
3, strong adaptability, that is, a wider range of exhaust, and not affected by the pressure level, can adapt to a wider range of pressure and cooling capacity requirements;
4, maintainability;
5, low material requirements, more common steel materials, processing easier, the cost is lower;
6. It is relatively mature in technology and has accumulated rich experience in production and use;
7, the device system is relatively simple;
Daily maintenance of piston compressor
1. Always look at the indicating instruments, such as pressure gauges, oil pressure gauges, thermometers, oil temperature gauges, etc., and pay attention to the lubrication conditions, such as the oiler, the fuel tank, and the lubrication points, and the flow of cooling water.
2, listen to the sound of machine operation. Such as air valve, piston, crosshead, crankshaft and bearings and Other parts of the sound is normal.
3. Diligently touch various parts to detect the temperature change and vibration of the compressor. Such as cooling the drainage temperature, oil temperature, operating temperature and vibration conditions, etc., and thus early detection of abnormal temperature rise and mechanical fastening. But pay attention to safety.
4. Diligently check the working condition of the entire machine and equipment, and handle the problem in time.
5, fill in the machine operation record form earnestly and responsibly.
6. Conscientiously do a good job in the safety and health of the engine room, keep the compressor clean, and do a good job in the handover work.
Piston compressor working principle
1, the compression process
The piston moves upward from the bottom dead center, the suction and exhaust valves are closed, and the gas is compressed in the closed cylinder. As the cylinder volume is gradually reduced, the pressure and temperature gradually increase until the gas pressure in the cylinder is equal to the exhaust pressure. The compression process is generally viewed as an isentropic process.
2, the exhaust process
As the piston continues to move upwards, causing the gas pressure in the cylinder to exceed the discharge pressure, the exhaust valve opens and the gas in the cylinder is forced out of the cylinder by the piston to enter the exhaust pipe until the piston moves to top dead center. At this point, due to the exhaust valve spring force and the gravity of the valve plate itself, the exhaust valve closes the exhaust.
At this point, the compressor completes a working cycle consisting of three processes of suction, compression, and exhaust. After this, the piston moves downward again, repeating the above three processes, so that the cycle is repeated. This is the ideal working process and principle of a piston refrigeration compressor.
Editor's summary: The characteristics of the piston compressor and the daily maintenance of the piston compressor are introduced here, and we hope to help everyone. If you want to know more related information, you can pay attention to this website information.
