【進(jìn)口不銹鋼絲扣過濾器】詳細(xì)說明
過濾器是輸送介質(zhì)管道上*的一種裝置,通常安裝在減壓閥、泄壓閥、定水位閥或其它設(shè)備的進(jìn)口端,用來消除介質(zhì)中的雜質(zhì),以保護(hù)閥門及設(shè)備的正常使用。當(dāng)流體進(jìn)入置有一定規(guī)格濾網(wǎng)的濾筒后,其雜質(zhì)被阻擋,而清潔的濾液則由過濾器出口排出,當(dāng)需要清洗時(shí),只要將可拆卸的濾筒取出,處理后重新裝入即可,因此,使用維護(hù)極為方便。
過濾器待處理的水由入水口進(jìn)入機(jī)體,水中的雜質(zhì)沉積在不銹鋼濾網(wǎng)上,由此產(chǎn)生壓差。通過壓差開關(guān)監(jiān)測(cè)進(jìn)出水口壓差變化,當(dāng)壓差達(dá)到設(shè)定值時(shí),電控器給水力控制閥,驅(qū)動(dòng)電機(jī)信號(hào),引發(fā)下列動(dòng)作:電動(dòng)機(jī)帶動(dòng)刷子旋轉(zhuǎn),對(duì)濾芯進(jìn)行清洗,同時(shí)控制閥打開進(jìn)行排污,整個(gè)清洗過程只需持續(xù)數(shù)十秒鐘,當(dāng)清洗結(jié)束時(shí),關(guān)閉控制閥,電機(jī)停止轉(zhuǎn)動(dòng),系統(tǒng)恢復(fù)至其初始狀態(tài),開始進(jìn)入下一個(gè)過濾工序。
Filter is an indispensable device in medium pipeline. It is usually installed at the inlet of pressure relief valve, pressure relief valve, constant water level valve or other equipment to eliminate impurities in medium, so as to protect the normal use of valves and equipment. When the fluid enters the filter cartridge with a certain size filter screen, its impurities are blocked, while the clean filtrate is discharged from the outlet of the filter. When cleaning is needed, only the removable filter cartridge is taken out and re-loaded after treatment. Therefore, the use and maintenance are very convenient.
The water to be treated by the filter enters the body from the water inlet, and impurities in the water deposit on the stainless steel filter mesh, resulting in pressure difference. The change of pressure difference between inlet and outlet is monitored by pressure difference switch. When the pressure difference reaches the set value, the hydraulic control valve of the electronic controller drives the motor signal to trigger the following actions: the motor drives the brush to rotate, cleans the filter core, and opens the control valve for sewage discharge. The whole cleaning process only lasts for tens of seconds, when cleaning. At the end, the control valve is closed, the motor stops turning, the system restores to its initial state and begins to enter the next filtering process.
【進(jìn)口不銹鋼絲扣過濾器】作用:
(1) 吸油過濾器:該過濾器設(shè)在泵的吸入管路上,濾除油箱內(nèi)的殘留污染物質(zhì)的通過空氣孔進(jìn)入的污染物,有保護(hù)泵的作用。但是為了避免泵產(chǎn)生空穴現(xiàn)象,必須充分注意壓力損失,一般使用100—200目的的粗金屬網(wǎng)或凹口金屬絲材料。因此,它不是控制系統(tǒng)的污染濃度的過濾器。
(2) 高壓管路過濾器(A):設(shè)在泵的出口管道上,有保護(hù)污染物不進(jìn)入系統(tǒng)的作用。因此,可以控制系統(tǒng)的污染物濃度。但是,因?yàn)槭歉邏褐鞴苈?,要受泵的脈動(dòng)和壓力沖擊,所以過濾元件的材質(zhì),強(qiáng)度要慎重考慮。
(3) 高壓管路過濾器(B):在系統(tǒng)中,為了保護(hù)對(duì)污染特別敏感的液壓件,才安裝此過濾器,也稱終端過濾器。因而它往往比其他過濾器的過濾粒度小。因此使用時(shí)要選擇容量大的。另外對(duì)元件的材質(zhì),強(qiáng)度也同(A)一樣要充分考慮。
(4) 回流過濾器:設(shè)在系統(tǒng)的回油管路上,其作用是把系統(tǒng)內(nèi)產(chǎn)生或侵入的污染物在返回油箱前捕獲到。因此它是控制系統(tǒng)污染濃度的zui有效zui重要的過濾器。雖是低壓管路,但根據(jù)傳動(dòng)裝置的運(yùn)轉(zhuǎn)狀況,也會(huì)出現(xiàn)脈動(dòng)或壓力沖擊,所以對(duì)元件材質(zhì)、強(qiáng)度要充分考慮。進(jìn)口泵
(5) 循環(huán)過濾器:設(shè)在油箱循環(huán)的回油路上,系統(tǒng)的容量大,所以在要求要求嚴(yán)格的清潔度時(shí)往往被采用,即使系統(tǒng)不在工作,也可以把油箱內(nèi)污染物捕集到,因此,降低污染濃度的效率。另外安裝著冷卻器,具有可以同時(shí)進(jìn)行冷卻、容易維修等優(yōu)點(diǎn)。但需要用泵和電機(jī),造價(jià)高。
(6) 空氣過濾器:設(shè)在油箱上,具有防止污染物由于油箱的油量變動(dòng)而隨空氣混入油箱。因此過濾精度要具有與過濾器同等以上的性能,容量要留有充分余地,以防由于孔阻塞使油箱內(nèi)壓變成負(fù)壓,引起泵的空穴現(xiàn)象。在周圍環(huán)境惡劣時(shí)尤其要注意。
