The pump is suitable for pumping air and other general gases. The forced oil inlet device of the oil pump is adopted, and the advantage of continuous operation is still available when the air inlet pressure is ≤1.33×103. It can be used alone, and can also be used for booster pumps, diffusion pumps, backing pumps for molecular pumps, maintenance pumps, and pre-pumps for titanium pumps. It is widely used in vacuum metallurgy, vacuum coating, vacuum drying, freeze drying, and vacuum dehydration. Gas, vacuum packaging, vacuum adsorption, vacuum forming, food packaging, printing, sputtering, vacuum casting, photovoltaics, aviation technology, chemical industry, electronics, refrigerators, air-conditioning assembly line characteristics and laboratories and other vacuum operations and supporting use.
1. Prepare a specially designed gas ballast valve to prevent the pump oil from mixing with water and prolong the service life of the pump oil;
2. High pumping efficiency, high ultimate vacuum and long service life;
3. Equipped with automatic anti-return oil check valve, never return oil;
3. Specially equipped with vacuum Drying Oven, freeze dryer, printing machinery, coating machine, etching machine, lighting, refrigerator assembly line, etc.;
4. It can be equipped with small-diameter conversion joints, KF interfaces, and flange interfaces;
5. When pumping steam, particles, and corrosive gases, auxiliary equipment such as condensers and dust collectors must be installed at the air inlet of the pump.
