ZJ/ZJP series roots vacuum pump
Summary
ZJ series Roots vacuum pump is a kind of rotary variable volume vacuum pump without internal compression, also known as mechanical booster pump.its advantage is in low inlet pressure has high extraction rate. It is one of the main pumping equipment to obtain medium and high vacuum at present. Its working principle is the same as roots blower. It is mainly composed of a pair of 8-shaped rotors rotating synchronously and high speed and two semicircle pump cavities Composition.
ZJ series Roots vacuum pump can't exhaust alone. It must be used in series with the front stage pump (such as slide valve pump rotary vane vacuum pump, water ring vacuum pump, oil ring pump, etc.). It can only start to work when the pressure in the pumping system is pumped to the acceptable pressure of Roots vacuum pump by the front stage vacuum pump, otherwise it will be damaged due to overload or overheating. ZJ series Roots vacuum pump is connected in series in front of the air inlet of the front stage pump to form a unit, which can improve the vacuum degree of the front stage pump and greatly improve the air extraction rate within the effective range. The limit pressure of ZJ series Roots vacuum pump is determined by the front stage pump. The data in the technical parameter table is the low limit pressure in the standard configuration (equipped with double stage oil seal mechanical vacuum pump).
ZJ series Roots vacuum pump has a large pumping speed in a wide pressure range(1-1x104 Pa).Beacause not sensitive to dust and water vapor contained in the extracted gas, it is widely used in vacuum casting, vacuum melting, vacuum degassing, vacuum distillation and vacuum drying in vacuum coating industry, chemical and pharmaceutical industry, etc
