概述 Overview
對于需要長時間無故障運行的設(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行過濾與自動反沖洗，從而實現(xiàn)無人值守下的不間斷運行。
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.技術(shù)參數(shù) Technical parameter

設(shè)計原理 Design principle
RZFL100過濾器在殼體內(nèi)擁有多個單獨過濾室，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。通過電控箱來控制電機、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行，相互獨立。
濾器的每個濾室逐一進行過濾與反沖洗，多腔室過濾器的設(shè)計構(gòu)成了整個過濾過程中的循環(huán)運動模式。
The RZFL100 filter features multiple individual filtering chambers within the shell, 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 of a certain chamber becomes clogged with dirt, another clean chamber takes over its function. The motor, solenoid valve, and other components are controlled by an electric control box, and the backwash action can be triggered by pressure difference or time, with a very fast and thorough process, ensuring that the filtering process and backwash process proceed simultaneously and independently of each other.
Each filtering chamber in the filter performs filtering and backwash one after another, and the design of multiple chamber filter constitutes a cyclic motion mode 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)
過濾液體進入濾器底部進口（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)，導致濾器進出口兩端的壓力差不斷上升，當壓力差達到某一特定值時，壓差發(fā)訊器即發(fā)出信號，接通減速電機（⑤），轉(zhuǎn)閥（⑥）從備用濾室轉(zhuǎn)到需清洗的濾室，滑閥（⑦）運動，反沖洗壓縮空氣經(jīng)過轉(zhuǎn)閥中空氣流道（⑧）進入上方濾室并促使液體反向流過濾芯，將粘接在濾網(wǎng)外面上的污物沖洗掉，從打開的排污口（⑨）排出。
經(jīng)過短時間的反沖洗，滑閥復位，排污口和反沖洗空氣進口關(guān)閉。經(jīng)反沖洗而排空的濾室重新補液并等待下一周期反沖洗。
此型號濾器還配備有加熱腔（⑩），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。Normal filtering state:
Liquid enters the filter at the bottom inlet (1), flows through the shell (2), and enters the filter element from the outside to the inside (3). Impurities larger than the specified filtering accuracy are retained by the filter mesh, and clean liquid after filtering flows out from the upper outlet of the filter (4).
Backwash state:
As the working time of the filter increases, 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, turning on the decelerating motor (5), and the rotary valve (6) transfers from the standby filter chamber to the filter chamber that needs to be cleaned. The slide valve (7) moves, and compressed air flows through the air passage in the rotary valve (8) into the upper filter chamber and urges the liquid to flow reversely through the filter element, flushing off the dirt adhering to the outside of the filter mesh and discharging it from the open drain port (9).
After a short period of backwash, the slide valve returns to its original position, closing the drain port and backwash air inlet. The filter chamber that has been emptied due to backwash is refilled with liquid and waits for the next backwash cycle.
This model of filter is also equipped with a heating chamber (10), which can be used to heat the filter interior while filtering heavy fuel oil by allowing steam or hot oil to flow through the heating chamber, providing insulation for the filter.
