在使用自動排水器時應(yīng)注意什么?

在冷干機(jī)（冷凍干燥機(jī)）中自動排水器可以說是很容易出故障的一個部件。螺桿空壓機(jī)廠家采用SKF雙平衡軸承和瑞士SPARK GROUP超耐磨高溫壓縮軸承，可以滿足500攝氏度范圍內(nèi)的高速回轉(zhuǎn)壓縮，軸承振幅超過GB10068-2000標(biāo)準(zhǔn)。

In the cold dryer (freeze dryer), the automatic drainer can be said to be a component that is easy to break down. Screw air compressor manufacturers use SKF double center balance bearing and Swiss spark group super wear-resistant high temperature compression bearing, which can meet the high-speed rotary compression within 500 ℃, and the bearing amplitude exceeds the standard of gb10068-2000.

采用大主機(jī)低轉(zhuǎn)速的設(shè)計原理，加大對主機(jī)與壓縮空氣含油量的控制，使空壓機(jī)在低壓4bar以下。變頻空壓機(jī)在設(shè)定所需壓力下機(jī)組會始終保持±0.1bar壓力的恒壓供氣；當(dāng)用氣量大時壓力保持不變而轉(zhuǎn)速自動補(bǔ)償，確保供氣需要；當(dāng)用氣量小時壓力保持不變而轉(zhuǎn)速自動降低，滿足僅夠用的氣量。

The design principle of low speed of large main engine is adopted, and the control of oil content of main engine and compressed air is emphasized to make the air compressor under 4 bar of low pressure. When the price of variable frequency air compressor is set at the required pressure, the unit will always maintain a constant pressure supply of ± 0.1bar; when the gas consumption is large, the pressure will remain unchanged and the speed will be automatically compensated to ensure the gas supply demand; when the gas consumption is small, the pressure will remain unchanged and the speed will be automatically reduced to meet the demand of only enough gas.

變頻軟啟動避免了電氣沖擊，避免機(jī)械沖擊；免除機(jī)組長時間高速運(yùn)行的不利因素；無接觸器，避免電接觸故障。原因是冷干機(jī)所排出的凝結(jié)（condensation）水并不是清潔水，而是混有固態(tài)雜質(zhì)(灰塵、銹泥等)、油污的稠狀液體(所以自動排水器又叫“自動排污器”)，這些雜質(zhì)是極易堵塞(dǔ sè)排水小孔。請注意定時對排水器進(jìn)行維護(hù)并裝拆順序?qū)ζ洳讳P鋼(不銹耐酸鋼)濾網(wǎng)(Filter mesh)進(jìn)行清洗，清水和皂液皆可。

Variable frequency soft start avoids electric shock and mechanical shock, avoids unfavorable factors of long-time high-speed operation, and avoids electric contact fault without contactor. The reason is that the condensation water discharged from the cold dryer is not clean water, but thick liquid mixed with solid impurities (dust, rust mud, etc.) and oil (so the automatic drainer is also called "automatic drainer"). These impurities are very easy to block (D ǔ s è) drainage holes. Please pay attention to the regular maintenance of the drainer and the sequence of assembly and disassembly, and clean the stainless steel (stainless acid resistant steel) filter mesh with clean water and soap.

另外，自動排水器要有一定壓力才能工作，例如常用的 RAD404（死頁面） 型自動排水器低工作氣壓是 0.15MPa，壓力太低會出現(xiàn)漏氣現(xiàn)象。空壓機(jī)生產(chǎn)廠家速度型壓縮機(jī)是回轉(zhuǎn)式連續(xù)氣流壓縮機(jī)，在其中高速旋轉(zhuǎn)的葉片使通過它的氣體加速，從而將速度能轉(zhuǎn)化為壓力。

In addition, the automatic drainer must have a certain pressure to work. For example, the commonly used rad404 (dead page) automatic drainer has a low working pressure of 0.15Mpa. If the pressure is too low, air leakage will occur. The speed compressor of air compressor manufacturer is a rotary continuous flow compressor, in which the high-speed rotating blade accelerates the gas passing through it, so that the speed can be converted into pressure.

這種轉(zhuǎn)化部分發(fā)生在旋轉(zhuǎn)葉片上，部分發(fā)生在固定的擴(kuò)壓器或回流器擋板上。但自動排水器壓力也不能超過額定值以防止貯水杯發(fā)生爆裂。在環(huán)境溫度低于零度時要放盡貯水杯內(nèi)的凝結(jié)水，以防結(jié)冰、凍裂。

This transformation takes place partly on the rotating blade and partly on the fixed diffuser or reflux baffle. However, the pressure of the automatic drainer should not exceed the rated value to prevent the water cup from bursting. When the ambient temperature is lower than zero, the condensate in the water storage cup should be drained to prevent freezing and cracking.
