關于(yu)水環式(shi)真空泵的溫度知識你知道多少？

日期： 2018-10-14
來源:
瀏覽(lan)次數: 275

水環式真空泵的介質溫度：

(1)水環式(shi)真空泵(beng)泵(beng)體內有必要(yao)補(bu)充冷卻作業液(ye)，

以(yi)補償運(yun)用中(zhong)隨氣(qi)體(ti)排出(chu)的(de)部分液(ye)(ye)體(ti)。作(zuo)業液(ye)(ye)的(de)作(zuo)業溫度一般在0~40℃之間(jian)，或(huo)低于沸點10℃。但為確保用(yong)最小量作業液(ye)到達最佳(jia)作業狀(zhuang)態，一(yi)般應將其溫度操控在15℃左右，這樣才干到達(da)液環(huan)式真空泵的(de)最佳效果。

(2)液環式真(zhen)空泵軸密(mi)封液(ye)與作業液(ye)應運用(yong)相同介質，

這樣能夠將(jiang)軸(zhou)密(mi)封液回收至(zhi)作業液中(zhong)，削減作業液用(yong)量，一般軸(zhou)密(mi)封液流量操控(kong)為0.5dm3/min。

(3)液環(huan)泵所抽輸的(de)介質有必要完全符合(he)產品(pin)運用要求，

即不溶于作業液，并且對泵體(ti)無腐蝕。一般抽輸介質溫(wen)度(du)應操控在(zai)0~80℃，因而咱們出(chu)產(chan)中所抽輸(shu)的窯氣溫度應預先降溫至80℃以下(xia)，方能到達最佳效果。

(4)因為真空泵所抽輸(shu)介質為窯(yao)氣，

含CO2，CO等有毒物質，為確保(bao)無滲漏，清洗中，應常(chang)常(chang)查看填料(liao)函是否到達預定密(mi)(mi)封液壓(ya)力，查看密(mi)(mi)封液流量或(huo)壓(ya)力指示值(zhi)，調理閥(fa)門(men)，確保(bao)密(mi)(mi)封液壓(ya)力正常(chang)，在(zai)這(zhe)種特別情況下，應該挑選具(ju)有防腐蝕性(xing)的(de)原料(liao)，如304、316、316L不銹鋼原料等等關于水環式真空泵的溫度


水環式真空泵的機體溫度：

一、水環式(shi)真空泵機體溫度原(yuan)因剖(pou)析

1、水(shui)環式(shi)真空泵(beng)電機功率大(da)，作業(ye)電流大(da)，發熱量大(da)。

2、電(dian)扇葉(xie)片數較少，發生的風量小。

3、電扇轉(zhuan)速低，風壓，風量小。

4、真(zhen)空(kong)泵(beng)電機(ji)地(di)點母(mu)線電壓(ya)為380V，因(yin)為(wei)電纜(lan)壓(ya)(ya)降及負荷分(fen)配不均(jun)，電機實踐所加電壓(ya)(ya)只要365V，真空(kong)泵(beng)電壓(ya)偏低形(xing)成運轉(zhuan)電流大。

5、電動機(ji)附有塵埃、油污，降低了散熱(re)才能(neng)。

二、水環真空(kong)泵溫(wen)度過(guo)高對策

水(shui)環式(shi)真空泵電(dian)(dian)(dian)(dian)機功率、轉(zhuan)(zhuan)速是(shi)和真空泵相匹配的，不能更改。電(dian)(dian)(dian)(dian)扇(shan)安裝于電(dian)(dian)(dian)(dian)機主軸上，電(dian)(dian)(dian)(dian)機轉(zhuan)(zhuan)速決議了電(dian)(dian)(dian)(dian)扇(shan)轉(zhuan)(zhuan)速，也不行替換。添加電(dian)(dian)(dian)(dian)扇(shan)葉(xie)片(pian)數量(liang)雖能起到(dao)必定效果，但葉(xie)片(pian)數量(liang)添加后，真空泵動平衡不容易找，如找正(zheng)不好，會引起電(dian)(dian)(dian)(dian)機振(zhen)蕩添加。

1、真空泵將原電扇(shan)罩加長40cm，在里面加裝一個(ge)與電(dian)扇(shan)罩(zhao)同直徑軸(zhou)流風(feng)機(ji)，軸(zhou)流風(feng)機(ji)電(dian)機(ji)功率850W，轉速1489r/min，電壓380V。原電扇持續保存。軸流風機另設一路電源操控，真空泵軸流風機與主電機不設連鎖。真空泵發動后及時發動軸流風機運轉，真空泵停運后30min停運軸(zhou)流風機，以使主電機得到充沛冷(leng)卻(que)；

2、真空泵定時鏟除電機(ji)上塵(chen)埃(ai)，堅持電機(ji)散熱片清潔，添加其散熱才能；

3、真空泵地點(dian)母線電壓調整為400V。
