ZJL型气体循环冷却罗茨真空泵

Model ZJL Roots Vacuum Pump with Circulated Gas-Cooling

特点/Features:

• 外置冷却器，泵可在很高的压差下工作而不发生热过载

The pump is equipped with external coolers, which enables the pump to work under high pressure difference without the risk of thermal overload.

• 工作范围宽，可直接排大气

The pump can be used in a wide range. Gas can be directly discharged to the atmosphere.

• 采用机械密封结构，并配合XYHZ-40稀油站使用，提供了一个洁净无油的真空抽气环境

The pump has a mechanical seal structure, coordinated with a XYHZ-40 diluted oil station. A clean, oil-free vacuum extraction environment is provided.

• 可与前级泵串联使用，也可以单独使用

The pump can be used in connection with the backing pump or used alone.

• 油气速率高

The pump has a high-speed pump rate.

• 该泵与自身或普通罗茨泵申联使用，对被抽系统无油污染

The pump can be used in connection with itself or with a Roots pump without oil pollution to the pump system.

应用/Application:

被广泛应用于极限压力不高而需要较大抽速的快速抽空场合, 被广泛应用于需要获得清洁无油污染的抽真空的场合。

The pump is widely applied to the situations which require higher pump rate of fast extracting because of lower ultra-pressure. It is also widely applied to the situations which require clean oil-free vacuum extraction.
