Many customers do not know how to select a vacuum pump when they buy a sewage pump. Here's how to choose a vacuum pump: The vacuum pump of the suction truck and suction truck plays a decisive role in the vehicle. When we choose a vacuum pump for the sewage suction truck and suction truck, we can greatly reduce the maintenance costs for the sewage suction truck and suction truck at a later stage. First, due to the environmental impact of oil effluent from the sewage suction truck and suction truck, you can choose oil-free vacuum pump oil steam or outdoor activities. It can reduce the working process of the vacuum pump and the influence of the environment. If the process does not allow, use a vibrating pump or take measures to prevent vibration. Second, the correct combination of suction pump and suction truck vacuum pump. Due to the selectivity of the suction vacuum pump, sometimes a pump can not be selected and several suction pumps are required to be combined to complement each other to meet the required suction. Since some vacuum pumps cannot work under atmospheric pressure, a pre-vacuum is required; some vacuum pump outlet pressures underneath the atmosphere require a foreline pump, so we need to use it in combination. Third, sewage suction trucks and suction trucks should be selected without a large number of oil pumps, such as: anhydrous ring pump, molecular sieve adsorption pump, sputter ion pump, cryogenic pump and so on. If not, you can choose an oil pump and add some measures to prevent oil pollution. Fourth, the correct choice of suction pump and suction truck vacuum pump operation. Each pump has a certain working pressure range, such as the diffusion pump is 100~10-7mmHg, in such a wide range of pump pressure, pressure and changing pumping speed, stable working pressure range is 5×10-4~5. ×10-6mmHg. Therefore, the range of pump operation should be chosen and it should not be allowed to work long-term at 10-8mmHg. And as titanium sublimation, the 10-2mmHg pump can work under pressure, but its work should be less than 1×10-5mmHg as well. Fifth, the vacuum pump of the sewage suction truck and the suction truck can come in all the gas volumes generated during the vacuum equipment process. Sixth, suction pump and suction truck choose vacuum pump, need to know, for the gas composition, pumped gas select the appropriate pump.
