The booster in the vacuum tower makes a hissing sound
Thread Content
Recently, the vacuum level in the pressure relief tower has been poor, and the booster also makes a hissing sound. Reducing the amount of steam used for evacuation reduces the hissing sound, but the vacuum level becomes even worse. What can be done to solve this problem? What’s going on? I’m dying of anxiety! !
There’s a problem with the cooling system at the back; the oil and gas don’t get cooled in time, which causes a buildup. If the water cooler gets scaled, it needs to be cleaned promptly; in the case of air cooling, measures must be taken to improve its cooling efficiency. I’m not sure what follows in your process.

To determine the cause: (1) Check the pressure of the vacuum system – compare it with the designed value or the value specified for the vacuum pump – to identify where the problem lies； If the back-pressure is high, it should be checked one by one; if it’s a problem with the gas system, then it’s quite simple ； The normal pressure drop i of the heat exchanger should be very low; caution is needed when determining whether the heat exchanger is clogged. (2) Check the unobstructed condition of the atmospheric leg, and at the same time verify whether the primary and secondary evacuators are drawing liquid; if so, reverse flushing with steam or water should be carried out promptly. (3) A well-made evacuator should create a low-temperature zone at its throat. By checking the temperature of the entire evacuator body, if a uniform temperature gradient can be established, it indicates that the evacuator is functioning properly. However, in the case of evacuators with abnormal temperatures, the issue could stem from problems with manufacturing precision, internal damage, or problems with the steam injector at the next stage; a comprehensive assessment is required. If questions 1 and 2 are excluded, the problem with the extractor is serious. (4) Common problems with vacuum pumps: 1) Since the nozzles of vacuum pumps are generally made of tin-copper and operate in harsh conditions, they can be punctured or worn out by steam ； 2) The sealing surface of the nozzle is prone to steam erosion leakage due to prolonged operation ； 3) Insufficient installation accuracy, such as the nozzle not being aligned with the housing, and the nozzle outlet and the oil-gas extraction port not being on the same horizontal plane. If this problem occurs, it is possible to keep the device running and schedule a shutdown for inspection at an appropriate time, but spare parts should be prepared in advance.
