With the rapid development of China's economy, China's vacuum pump industry has maintained a rapid growth momentum, and to achieve sustained and stable development. At the same time, the vacuum pump enterprises and users are constantly exploring how to promote the efficient operation of the vacuum pump, which is the impact of the efficiency of the vacuum pump, what?.
Influence factors:
1, steam pressure
Steam pressure is low and the pressure fluctuations have a greater impact on the capacity of the vacuum pump, so the steam pressure should not be less than the requirements of the work pressure, but the structure of the vacuum pump has been designed to be finalized, too much steam pressure and will not increase the pumping capacity and vacuum degree. In addition, to ensure that the boiler supply steam pressure is stable, it is best to use a special boiler steam injection pump to provide steam, so that the steam pressure will not fluctuate, to ensure the performance of the vacuum pump.
2, circulating cooling water
The cooling water supply is insufficient, the condenser will heat, the air flow sound becomes big, the vacuum degree drops rapidly, even the steam can return to the pumping tube. Condensate water in a multi-stage vacuum pump has a pivotal role in the condensation of water vapor can be fully condensed, vacuum pump discharge pressure in the water vapor pressure is higher than the corresponding full steam pressure, so the temperature of the condensate is also less than the full temperature of the pressure to ensure the normal operation of the pump.
3, nozzle
Nozzle is an important part of the vacuum pump performance, the existing problems are: the nozzle is loaded with the wrong, the device is crooked, the plug, damage, corrosion and leakage, no matter what preventive measures, the nozzle is inevitable. On the one hand, due to the installation of steam pipe, the remaining pipe and welding slag iron will jam the nozzle; on the other hand, vacuum pump system is disabled, the steam pipe rust, rust in use drop nozzle clogging.
4, the use of the environment
Environmental impact is mainly refers to has been pumping gas to the system of pollution, in the disposal process of liquid steel and molten steel will emit many gases, there will also be a small part of the oxidation of jelly sheet small particles are sucked into the vacuum pump, these small particles would deposit adhesion on the pump body, reduce the conductance of the smoke and gas pipeline and extend the pumping time and decrease the pumping function.
Through the introduction, we can understand the impact of the vacuum pump efficiency of the factors that have what. In the future use of the process, to avoid these errors, to better use the vacuum pump.
