How to reduce the exhaust temperature of compressor?

A, air temperature

Reduce the intake air temperature can effectively reduce the exhaust gas temperature, and at all levels of intake air temperature and intercooler coolingimperfection, therefore, should try to ensure the cooling effect of the middle coolercooling suit one's measures to local conditions, or adopt some special measures to reduce the intake air temperature, and strive to reduce exhaust temperature.

Two, reducing intake, exhaust pressure loss

The intake cylinder end temperature is one of the exhaust temperature, and intake temperature and exhaust pressure, loss, so the compressor in installation and repair,should pay attention to the spring valve selection, valve in the prerequisite of ensuring the normal operation of the next, as far as possible, reduce the pressure loss of exhaust, in order to reduce the exhaust the purpose of temperature.

Three, strengthen the cylinder cooling to reduce exhaust temperature

Compression index will also affect the exhaust temperature. In actual operation, the compression process index is mainly related with the cylinder cooling condition. The cooling effect is better, the index is small, the exhaust temperature is low. Therefore,can reduce the exhaust gas temperature by strengthening the cooling cylinder.

Four, to prevent leakage

Practice shows that, internal leakage is caused by the exhaust temperature is higher,even too much of one of the most important reasons. Especially in the compressor of a certain level of expansion and the suction process, if the exhaust valve closure lax,resulting in high temperature and high pressure gas exhaust pipe before cooling andreflux (leakage) to the cylinder, will make the exhaust temperature rise rapidly.Therefore, special attention should be paid to prevent the occurrence of such a situation.

Five, adjust the clearance volume

For multistage compressor, to adjust or reduce the exhaust temperature, the situationis often not a single. For example, if a level high exhaust temperature, if theadjustment (increase) the clearance volume measures, appropriate to reduce thelevel of pressure ratio, although this can make the exhaust temperature decreased,but will make the previous stage pressure ratio increases, the exhaust temperaturerise; if attempting to strengthen the air cylinder cooling, reduce the compression indexmeasures to reduce the exhaust temperature, it also makes the stage pressure ratio decreases, a pressure level of exhaust gas temperature increase than rising and post; when the strengthening intercooler cooling effect of the level before, although can through the air temperature in order to reduce exhaust temperature, but the intake pressure of the level is reduced, so that the pressure increased, thus reducing the exhaust temperature of the role is not obvious. So the need to take comprehensive methods, such as strengthening the cooling in front at the same time,and an appropriate increase in the level of clearance volume, the stage pressure ratio unchanged, it can not only effectively reduce the exhaust temperature, but alsodoes not influence its front, after the level of exhaust temperature.
