Ikhoyili yevalve ye-Solenoid ye-DH55 yokutshixa ukhuseleko lomqhubi we-Doosan excavator

Ukufunyanwa kwekhoyili yevalve ye-solenoid

Sebenzisa i-multimeter ukulinganisa ukuxhathisa kwevalve ye-solenoid.Ukuchasana kwekhoyili kufuneka kube malunga ne-100 ohms.Ukuba ukuchasana kwekhoyili akunasiphelo, kuthetha ukuba iphukile.Unako kwakhona ukufaka umbane ikhoyili yevalve ye-solenoid kwaye ubeke iimveliso zentsimbi kwivalve ye-solenoid, kuba ivalve ye-solenoid ineempawu zemagneti zokutsala iimveliso zentsimbi emva kokuba i-coil yevalve ye-solenoid ifakwe umbane.Ukuba unako ukubamba imveliso yentsimbi, oko kuthetha ukuba ikhoyili ilungile, kodwa ithetha ukuba ikhoyili yaphukile.Indlela yokufumanisa isiphaluka esifutshane okanye isiphaluka esivulekileyo se-solenoid valve coil kukulinganisa i-on-off kunye ne-multimeter kuqala, kwaye ixabiso lokumelana lisondela kwi-zero okanye i-infinity, oku kuthetha ukuba i-coil yi-short circuit okanye i-circuit evulekile.Ukuba uxhathiso olulinganisiweyo luqhelekile, oko akuthethi ukuba ikhoyili kufuneka ilungile.Kufuneka kwakhona ufumane i-screwdriver encinci kufuphi nentonga yentsimbi edlula kwikhoyili yevalve ye-solenoid, kwaye emva koko ufake umbane kwivalve ye-solenoid.Ukuba iva imagnethi, ngoko ke i-coil yevalve ye-solenoid ilungile, ngaphandle koko imbi.

Ukuqaliswa kwekhoyili yevalve ye-solenoid yokulinga

Umgaqo: Xa amandla evuliwe, amandla e-electromagnetic avula umngxuma wokulingwa, kwaye uxinzelelo olukwigumbi eliphezulu lwehla ngokukhawuleza, lwenza umahluko woxinzelelo phakathi kwaphezulu nasezantsi malunga neqhekeza lokuvala, kwaye uxinzelelo lolwelo lutyhala iqhekeza lokuvala ukuya phezulu. , ngaloo ndlela uvula ivalve;Xa umbane unqunyulwe, umngxuma wokulinga uvalwa ngamandla entwasahlobo, kwaye uxinzelelo lokungena lwenza ngokukhawuleza umahluko woxinzelelo oluphantsi oluphezulu malunga nevalve yokuvala ngomngxuma wokudlula, kwaye uxinzelelo lolwelo lutyhala ilungu elivalayo ukuba liye ezantsi ukuya. vala ivalve.

I-1: Umda ophezulu woluhlu loxinzelelo lwe-fluid luphezulu, olunokuthi lufakwe ngokuthanda (ukwenza ngokwezifiso) kodwa kufuneka luhlangabezane nemeko yokuhluka koxinzelelo lwamanzi.

2. Ngokweyantlukwano kwisakhiwo sevalvu kunye nezinto kunye nomgaqo, iivalve ze-solenoid zinokuhlulwa zibe ngamacandelwana amathandathu: ulwakhiwo lwe-diaphragm olusebenza ngokuthe ngqo, ulwakhiwo lwe-diaphragm olusebenza ngokuthe ngqo, i-pilot ye-diaphragm, i-piston esebenza ngokuthe ngqo. isakhiwo, inyathelo-nge-nyathelo-inyathelo ngqo-i-piston isakhiwo kunye nesakhiwo piston pilot.

3. Izivalo ze-solenoid zihlelwa ngokwemisebenzi yazo: ivalve yamanzi, ivalve ye-solenoid yomphunga, ivalve ye-solenoid efrijini, ivalve ye-solenoid ephantsi, i-valve ye-solenoid yegesi, i-valve ye-solenoid yomlilo, i-valve ye-solenoid ye-ammonia, i-valve ye-solenoid yegesi, i-valve ye-solenoid engamanzi, i-solenoid encinci. ivelufa, ivalve solenoid pulse, hydraulic solenoid valve, oil solenoid valve, DC solenoid valve, high pressure solenoid valve, explosion-proof solenoid valve, njl.
