3. Technical Specifications and Description 技术参数和配置详述

3.1 Dry Screw Vacuum Pump螺杆真空泵PS1302-CC2

PS1302为单级压缩，水冷式，无油干式螺杆真空泵组，特殊的螺杆设计确保干泵低温且高效运行。

PS1302 is a single stage, water cooled, dry running screw vacuum pump unit. The special designed screw gives high efficiency and low internal temperatures.

它的主要特点如下：

Its major features are :

低温，干式，无油无水的纯净系统运行，可大大减少污染。

- Cool, Dry running, oil and water free pumping, to minimise pollution.

无接触式压缩，可确保无磨损运行。

- Non-contact compression for wear free operation.

对液体有一定的兼容性，适合抽取冷凝性气体，及一定量的固体颗粒杂质。

- High tolerance to proper liquid carry-over, condensate and process solids.

允许就地使用氮气，合适的蒸汽，溶剂等冲洗泵体。

- Designed to allow cleaning in-situ, with N2, steam, solvent etc.

迷宫式密封，结合氮封

- Labyrinth seals， with N2 sealing

操作使用方便，几乎免维护。

- Easy to operation, almost no maintenance.

3.2间接水冷系统Indirect Cooling System：

间接水冷却系统含副水箱(内部有冷却液)，通过外接冷却水冷却冷却液,最大限度的保护了真空泵，避免了温度过高对泵产生的不良影响；

The water cooling system consists of the expansion tank which contains cooling liquids, the fresh cooling water cools the cooling liquids, it mostly protect the pump damage from the higher temperature.

冷却水流量：不少于4L/min

Cooling water: No less than 4L/min

冷却水进水温度：15~30℃

Temperature of the cooling water supply: 15~30℃

冷却水供水压力：2-4 bar，排水无背压

Pressure of the cooling water supply: 2-4 bar, water return no pressure

3.3 氮气吹扫系统Nitrogen purge system

进气口气体吹扫接口，可根据实际工艺情况选择使用。干燥氮气吹扫有利于帮助将可凝性气体彻底排出。也可用于低温条件下帮助预热真空泵。

One port for pump stop purge at the pump inlet, customer can choose use it or not. Nitrogen purge is helpful for removing the condensate, and it also can help to warm the pump under low temperature.

氮气密封保护可有效防止工艺气体从泵腔密封处泄漏到油箱使润滑油性能下降造成对泵的损坏。

Nitrogen-sealed protection purge can prevent the process gas leaking to the oil box then damage the pump by decreasing the capability of the oil.

-氮气吹扫管路路附件Nitrogen purge system piping connection：

N2 pressure gauge

N2 pressure regulator

3.4排气消音器及排气止回阀， Discharge silencer and Discharge check valve

排出管路配有不锈钢消音器，降低噪音.排气止回阀，防止气体返流。
