變壓器油過濾裝置
CMM-1.0LT TRANSFORMER OIL PURIFICATION UNIT 型號：CMM-1.0LT-
CMM-1.0LT 裝置設計用於工業油的熱真空乾燥和過濾，這些油用於燃氣輪機和燃氣泵組的潤滑、密封、液壓控制系統，燃氣發動機壓縮機，以及變壓器中。除了油的淨化，CMM-1.0LT還可用於加熱和乾燥充滿油的電氣設備。
操作原理
由真空驅動的油通過一個過濾細度為200μm的粗濾器，然後進入一個裝有加熱器的真空罐中。從底部到頂部上升，油被加熱，並通過一個特殊的通道蓋子進入腔室的另一部分，直接進入特殊的填充物。接下來，油順著填充物裝置流下，而水份和氣體則通過真空從油中去除。然後，油從罐底通過兩個精細的過濾器被抽出到設備出口。過濾器的過濾細度可以選擇5、3、1或0.3μm。
設計特點
通過將加熱器置於真空罐內，設備被縮小，油加熱過程中的熱損失被減少。真空系統產生的低壓將油引向真空罐。其它部件也採用了新的佈局。這些創新在設備縮減方面產生了良好的效果。
優勢
- 體積小。
- 推車形式，方便移動。
- 容易操作。
- 適用於過濾各種類型的工業油：如 : 渦輪機、液壓機、壓縮機等。

CMM-1.0LT unit is designed for thermal vacuum drying and filtration of industrial oils used in lubrication, sealing, hydraulic control systems of gas turbine and gas pumping units, gas engine compressors, and in transformers. In addition to oil purification, CMM-1.0LT may be used for heating and drying the oil-filled electrical devices.
Principle of operation
The oil driven by vacuum passes through a coarse filter with the filtration fineness of 200 microns after which it gets inside a vacuum tank where a heater is located. Rising from bottom to top, the oil heats up and gets into the other part of the chamber through a special channeled lid coming directly to special fillers. Next, the oil flows down the fillers, while the moisture vapor and gases are removed from the oil by vacuum. Then, the oil is pumped out from the tank bottom through two fine filters to the unit outlet. The filtration fineness of the filters can be selected at 5, 3, 1, or 0.3 microns.
Design features
The heater is located inside the vacuum tank which made it possible to reduce the unit dimensions and to diminish the heat losses while heating the oil.
The oil is sucked into the vacuum chamber due to the underpressure generated by a two-stage vacuum system consisting of a backing pump and a booster pump. A new layout has been applied to the rest of the unit components. All of these innovations have given good results in terms of the small equipment size.Advantages
- сompactness;
- mobility;
- ease of control;
- used to purify industrial oils of various types: turbine, hydraulic, compressor, etc.
