概述 Overview
對于需要長時間無故障運(yùn)行的設(shè)備而言，所用液體燃料、潤滑劑或冷卻液的清潔度至關(guān)重要。自清濾器采用多濾芯結(jié)構(gòu)，適用于燃油、潤滑油以及乳化液等多種液體介質(zhì)且保證足夠的過濾能力。且本系列濾器在維持系統(tǒng)壓力恒定的情況下可以同時進(jìn)行過濾與自動反沖洗，從而實現(xiàn)無人值守下的不間斷運(yùn)行。
For equipment that requires long-term trouble-free operation, the cleanliness of the liquid fuel, lubricant, or coolant used is critical. The self-cleaning filter uses a multi-element structure, suitable for a variety of liquid media such as fuel, lubricant, and emulsion, and ensures sufficient filtration capacity. And this series of filters can simultaneously perform filtration and automatic backwash while maintaining constant system pressure, enabling unattended, uninterrupted operation.

設(shè)計原理 Design principle
RZFL32、50過濾器包含兩個單獨(dú)的過濾室，每個過濾室內(nèi)都配備了各自的濾芯組件用來提供很大的過濾面積。
該濾器多個濾室的設(shè)計提供了當(dāng)某個濾室的濾芯積滿污物時，另一個潔凈濾室接管其工作的條件。通過電控箱來控制執(zhí)行器、電磁閥等部件，反沖洗動作可根據(jù)壓差或時間觸發(fā)，過程極為快捷、徹底，保證了過濾過程和反沖洗過程同步進(jìn)行，相互獨(dú)立。
濾器的兩個濾室輪流進(jìn)行過濾與反沖洗，雙腔室過濾器的設(shè)計構(gòu)成了整個過濾過程中的循環(huán)運(yùn)動模式。
The RZFL32 and 50 filters include two separate filter chambers, each equipped with its own filter element assembly to provide a large filtering area.
The design of multiple filter chambers in the filter provides the condition where when the filter element in one chamber becomes clogged with dirt, another clean chamber takes over its operation. The control of the actuator, solenoid valve, and other components is through the electric control box. The backwash action can be triggered by pressure difference or time, and the process is extremely fast and thorough, ensuring that the filtering process and backwash process are synchronized and independent of each other.
The two filter chambers of the filter take turns in filtering and backwashing, and the design of a dual-chamber filter constitutes a cyclic mode of operation throughout the entire filtering process.濾器外形 Filter contour

工作過程 Working process
1. 正常過濾狀態(tài)
過濾液體進(jìn)入濾器底部進(jìn)口（①），流經(jīng)殼體（②），由外向內(nèi)通入濾芯（③），其中大于規(guī)定過濾精度的雜質(zhì)被濾網(wǎng)滯留，過濾后的清潔液體由濾器上端出口（④）流出。
2. 反沖洗狀態(tài)
隨著濾器工作時間的增加，越來越多的被滯留在濾芯上的雜質(zhì)，導(dǎo)致濾器進(jìn)出口兩端的壓力差不斷上升，當(dāng)壓力差達(dá)到某一特定值時，壓差發(fā)訊器即發(fā)出信號，執(zhí)行器（⑤）動作，轉(zhuǎn)閥（⑥）從備用濾室轉(zhuǎn)到需清洗的濾室，滑閥（⑦）向上運(yùn)動，儲氣室（⑧）內(nèi)釋放反沖洗壓縮空氣促使濾室中的液體反向流過濾芯，將粘接在濾網(wǎng)外面上的污物沖洗掉，流經(jīng)轉(zhuǎn)閥下部，從打開的排污口（⑨）排出。
經(jīng)過短時間的反沖洗，滑閥復(fù)位，排污口和反沖洗空氣進(jìn)口關(guān)閉。經(jīng)反沖洗而排空的濾室重新補(bǔ)液并等待下一周期反沖洗。
此型號濾器還配備有加熱腔，可在過濾重燃油的同時，讓蒸汽或熱油流過加熱腔，對濾器內(nèi)部起保溫功能。1. Normal filtering condition
Filtered liquid enters the filter at the bottom inlet (1), flows through the shell (2), and is filtered from the outside to the inside through the filter element (3). Impurities larger than the specified filtering accuracy are retained by the filter net, and the cleaned liquid exits from the upper end of the filter at the outlet (4).
2.Backwash State
As the filter works for a long time, more and more impurities are trapped on the filter element, causing the pressure difference between the inlet and outlet of the filter to continue to rise. When the pressure difference reaches a certain specific value, the pressure difference transmitter sends a signal, the actuator (5) operates, and the rotary valve (6) transfers from the backup filter chamber to the filter chamber that needs to be cleaned. The slide valve (7) moves upward, releasing compressed air in the gas storage chamber (8) to make the liquid in the filter chamber flow reversely through the filter element, washing off the dirt adhering to the outside of the filter net. The liquid flows through the lower part of the rotary valve and is discharged from the open drain port (9).
After a short period of backwash, the slide valve returns to its original position, closing both the drain port and backwash air inlet. The filter chamber that has been drained and washed re-fills with liquid and waits for the next backwash cycle.
This type of filter is also equipped with a heating chamber that can be used to heat filter oil or other fuels while filtering heavy fuel oil, keeping the interior of the filter warm.
