3.  Technical Specifications and Description 技術(shù)參數(shù)和配置詳述

3.1 Dry Screw Vacuum Pump螺桿真空泵PS1302-CC2

PS1302為單級壓縮，水冷式，無油干式螺桿真空泵組，特殊的螺桿設(shè)計確保干泵低溫且高效運行。

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

它的主要特點如下：

Its major features are :

低溫，干式，無油無水的純凈系統(tǒng)運行，可大大減少污染。

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

無接觸式壓縮，可確保無磨損運行。

- Non-contact compression for wear free operation.

對液體有一定的兼容性，適合抽取冷凝性氣體，及一定量的固體顆粒雜質(zhì)。

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

允許就地使用氮氣，合適的蒸汽，溶劑等沖洗泵體。

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

迷宮式密封，結(jié)合氮封

- Labyrinth seals， with N2 sealing

操作使用方便，幾乎免維護。

- Easy to operation, almost no maintenance.

3.2間接水冷系統(tǒng)Indirect Cooling System：

  間接水冷卻系統(tǒng)含副水箱(內(nèi)部有冷卻液)，通過外接冷卻水冷卻冷卻液,最大限度的保護了真空泵，避免了溫度過高對泵產(chǎn)生的不良影響；

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.

冷卻水流量：不少于4L/min

  Cooling water: No less than 4L/min

  冷卻水進水溫度：15~30℃

  Temperature of the cooling water supply: 15~30℃

  冷卻水供水壓力：2-4 bar，排水無背壓

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

3.3 氮氣吹掃系統(tǒng)Nitrogen purge system

進氣口氣體吹掃接口，可根據(jù)實際工藝情況選擇使用。干燥氮氣吹掃有利于幫助將可凝性氣體徹底排出。也可用于低溫條件下幫助預(yù)熱真空泵。

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.

氮氣密封保護可有效防止工藝氣體從泵腔密封處泄漏到油箱使?jié)櫥托阅芟陆翟斐蓪Ρ玫膿p壞。

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.

-氮氣吹掃管路路附件Nitrogen purge system piping connection：

 N2 pressure gauge

N2 pressure regulator

3.4排氣消音器及排氣止回閥， Discharge silencer and Discharge check valve

排出管路配有不銹鋼消音器，降低噪音.排氣止回閥，防止氣體返流。

  Discharge silencer at discharge line will reduce noise and discharge check valve avoid the gas sucked back
