Comprehensively understand the components of the food vacuum packaging machine to be pumped, the gas contains no condensable vapor, whether there is particulate dust, corrosiveness, toxicity, etc. The actual choice of the vacuum pump needs to know the components of the pumped gas. Select the appropriate pump for the gas. If it is a corrosive gas, the cavity material of the pump should be selected from anti-corrosive materials. If it is a toxic gas, the vacuum pump needs to consider the leakage rate to avoid accidents caused by the leakage of toxic gas. Condensable vapor, particles and corrosive gases, so you can consider installing auxiliary equipment, such as condensers, dust collectors, etc. on the pump's inlet pipe. Food vacuum packaging machine equipment for oil pollution requirements, if the equipment strictly requires no oil, you should choose a variety of oil-free pumps. If the requirements are not strict, you can basically choose an oil pump and add some measures to prevent oil pollution, such as adding cold traps, baffles and oil traps, so as to meet the requirements of clean vacuum.
The impact of food vacuum packaging machine on the environment is not allowed to have any oil pollution. An oil-free vacuum pump can be used. The environment does not allow any dust pollution. You can choose a pump without abrasive debris, such as a floating scroll pump and an oil-free diaphragm pump. Wait, the environment is not allowed to have noise pollution, you can choose a silent pump. The cost factor of food vacuum packaging machine, the cost of vacuum pump should consider the one-time purchase cost and its comprehensive use cost. The one-time cost is the cost of the vacuum pump itself, the supporting costs of the surrounding pipelines, and the cost of comprehensive use. It also includes the daily operation and maintenance costs and the cost of its use time.
