Tisati tasarudza sefa chinhu, tinofanira kutanga tajekesa kusanzwisisa kuviri:

(1) Kusarudza chinhu chesefa neicho chakarongeka (Xμm) chinogona kusefa zvese zvimedu zvakakura kupfuura izvi.

Parizvino, kukosha kwe β kunowanzo shandiswa pasi rose kumiririra kusefa kwesefa yechinhu. Iyo inodaidzwa kuti β kukosha inoreva chiyero chehuwandu hwezvikamu zvakakura pane imwe saizi mumvura painopinza yesefa element kusvika kuhuwandu hwezvikamu zvakakura pane imwe saizi mumvura painobuda yesefa element. . Naizvozvo, iyo yakakura iyo β kukosha, ndiyo yakakwirira kusefa kweiyo sefa element.

Zvinogona kuoneka kuti chero chinhu chesefa ndeye hukama chaihwo kutonga, kwete mhedziso chaiyo yekutonga. Semuenzaniso, kunyatsoita kusefa kwePALL Corporation muUnited States kunogadziriswa kana β kukosha yakaenzana ne 200. Pakusarudza chinhu chesefa, kunze kwekunatsa kwesefa uye kushanda zvakanaka kwefiltration, zvinhu uye maitiro ekugadzirisa chikamu chesefa inofanirawo zvakare. kutariswa, uye zvigadzirwa zvine high pressure kudonha, high fluidity uye hupenyu hurefu hwebasa hunofanirwa kusarudzwa.

(2) The calibrated (nominal) flow rate of the filter element ndiyo chaiyo yekuyerera mwero wesystem.

Mumakore achangopfuura, iyo data yekusarudza yakapihwa nevagadziri vepamba mafirita havawanzo kutaura hukama pakati peyakatemerwa kuyerera kweiyo sefa chikamu uye chaiyo yekuyerera mwero weiyo sisitimu, izvo zvinoita kuti sisitimu yedhizaini ive nekunyepedzera kuti yakatemerwa kuyerera mwero. chesefa element ndiyo chaiyo yekuyerera mwero weiyo hydraulic system. Zvinoenderana neruzivo rwakakodzera, iyo yakatemerwa kuyerera kweiyo sefa chikamu chiyero chekuyerera kwemafuta anopfuura neakachena sefa chinhu pasi peyakatsanangurwa yepakutanga kuramba apo mafuta viscosity iri 32mm2/s. Nekudaro, mukushandisa zvinoshanda, nekuda kweiyo midhiya yakasiyana inoshandiswa uye tembiricha yehurongwa, viscosity yemafuta ichachinja chero nguva. Kana iyo sefa chinhu chakasarudzwa zvinoenderana neyakayerwa kuyerera uye iyo chaiyo yekuyerera mwero we1: 1, kana viscosity yeoiri system yakakura zvishoma, kuramba kwemafuta anopfuura nepasefa chinhu kunowedzera (semuenzaniso, viscosity ye. No. 32 hydraulic oil pa 0 ° C inenge 420mm2 / s) , Kunyange kusvika kune kukosha kwekuvharidzirwa kwekusvibiswa kwesefa, chinhu chesefa chinofungidzirwa kuti chakavharwa. Kechipiri, iyo sefa yechinhu chesefa chikamu chakapfekwa, icho chinosvibiswa zvishoma nezvishoma panguva yebasa, iyo chaiyo inoshanda yekusefa nzvimbo yesefa zvinhu inoramba ichidzikiswa, uye kuramba kwemafuta kupfuura nepakati pesefa inokurumidza kusvika chiratidzo chekukosha kweiyo pollution blocker. Nenzira iyi, iyo sefa chinhu chinoda kucheneswa kana kutsiviwa kazhinji, izvo zvinowedzera mutengo wekushandisa wemushandisi. Izvo zvakare zvinokonzeresa zvisina basa kudzika kana kumisa kugadzirwa nekuda kwevanorasisa vashandi vekugadzirisa.

Iyo yakakwirira yekusefa kweiyo hydraulic sefa element, zviri nani?

Iyo yepamusoro-chaiyo yekusefa mhedzisiro yakanaka, asi uku ndiko kusanzwisisa kukuru. Iko kurongeka kweiyo hydraulic mafuta sefa chinhu chinodiwa neiyo hydraulic system haisi "yakakwirira" asi "yakakodzera". Yakakwirira-chaiyo hydraulic oiri sefa zvinhu zvine hushoma-kupfuura kugona kwemafuta (uye iko kurongeka kweiyo hydraulic mafuta sefa zvinhu zvakaiswa munzvimbo dzakasiyana hazvigone kufanana), uye yakakwirira-chaiyo hydraulic mafuta sefa zvinhu zvinonyanya kuvharika. Imwe inguva pfupi yehupenyu uye inofanirwa kutsiviwa kazhinji.

Matanho ekusarudza mafuta eHydraulic

Iyo general sarudzo ine nhanho dzinotevera:

① Tsvaga izvo zvinonyanya kutarisisa kusvibiswa muhurongwa, uye uone kuchena kunodiwa nehurongwa;

②Sarudza nzvimbo yekuisa, fomu yekusefa uye giredhi rekuyerera kwegiredhi resefa element;

③Maererano neyakagadzika yekumanikidza musiyano uye nhanho yekuyerera, tarisa kune iyo β kukosha curve yeakasiyana mafirita zvinhu, uye sarudza iyo sefa chinhu uye kureba. Tsvaga iyo goko rekumanikidza kudonhedza uye kusefa element kudzvinyirirwa kudonha kubva pamuenzaniso chati, wobva waverenga mutsauko wekumanikidza, unonzi: △p sefa chinhu ≤△p sefa chinhu kuseta; △p musangano≤△p kugadzwa kwegungano. Imwe neimwe sefa element mugadziri muChina yakatemerwa chiyero chekuyerera kweiyo sefa chinhu chinogadzirwa navo. Zvinoenderana nezvakaitika kare uye mashandisirwo evatengi vazhinji, kana mafuta anoshandiswa muhurongwa ari general hydraulic oiri, zvinokurudzirwa kuti iyo sefa chinhu chisarudzwe zvinoenderana neanotevera akawanda ekuyerera. :

a The rated flow of the oil suction and oil return filters is more than 3 times the real flow of the system;

b Kuyerera kwakayerwa kwepipeline sefa chinhu chinodarika 2.5 nguva yekuyerera chaiko kwehurongwa. Pamusoro pezvo, zvinhu zvakaita senzvimbo yekushanda, hupenyu hwesevhisi, chikamu chekutsiva frequency, uye sisitimu yekusarudza midhiya inofanirwawo kutariswa nemazvo kuti izadzise chinangwa chekugadzirisa mafirita esarudzo.

Chengetedzo yekuisa hydraulic oiri sefa chinhu

Nzvimbo yekuisa inofanira kutariswa, iyo iriwo chikamu chakakosha zvikuru. Kana iwe usina chokwadi chekuiisa, haugone kusarudza iyo hydraulic oiri sefa chinhu. Basa uye kurongeka kweiyo hydraulic oiri sefa chinhu munzvimbo dzakasiyana siyana zvakare.
