在冷干机(冷冻干燥机)中自动排水器可以说是很容易出故障的一个部件。螺杆空压机厂家采用SKF双重心平衡轴承和瑞士SPARK GROUP超耐磨高温压缩轴承,可以满足500摄氏度范围内的高速回转压缩,轴承振幅超过GB10068-2000标准。

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.

采用大主机低转速的设计原理,重点加大对主机与压缩空气含油量的控制,使空压机在低压4bar以下。变频空压机价格在设定所需压力下机组会始终保持±0.1bar压力的恒压供气;当用气量大时压力保持不变而转速自动补偿,确保供气需要;当用气量小时压力保持不变而转速自动降低,满足仅够用的气量。

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.

变频软启动避免了电气冲击,避免机械冲击;免除机组长时间高速运行的不利因素;无接触器,避免电接触故障。原因是冷干机所排出的凝结(condensation)水并不是清洁水,而是混有固态杂质(灰尘、锈泥等)、油污的稠状液体(所以自动排水器又叫“自动排污器”),这些杂质是极易堵塞(dǔ sè)排水小孔。请注意定时对排水器进行维护并装拆顺序对其不锈钢(不锈耐酸钢)滤网(Filter mesh)进行清洗,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,自动排水器要有一定压力才能工作,例如常用的 RAD404(死页面) 型自动排水器低工作气压是 0.15MPa,压力太低会出现漏气现象。空压机生产厂家速度型压缩机是回转式连续气流压缩机,在其中高速旋转的叶片使通过它的气体加速,从而将速度能转化为压力。

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.

这种转化部分发生在旋转叶片上,部分发生在固定的扩压器或回流器挡板上。但自动排水器压力也不能超过额定值以防止贮水杯发生爆裂。在环境温度低于零度时要放尽贮水杯内的凝结水,以防结冰、冻裂。

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.
