PC200-6 PC300-6 valavu yayikulu yothandizira mfuti 708-2L-04312

Valavu yopumira yofukula ma hydraulic ili ndi ntchito zinayi zazikulu:

1, mu mpope wochulukira (pampu ya giya) ma hydraulic system, omwe amagwiritsidwa ntchito kusefukira mafuta ochulukirapo kubwerera ku thanki kuti asunge kuthamanga kwa hydraulic system (pafupifupi nthawi zonse).

2, mu makina osinthika a pampu ya hydraulic, pokhapokha ngati kupanikizika kumaposa mtengo wamtengo wapatali wokonzedweratu, kusefukira kumatsegulidwa, kotero kuti kupanikizika kwa dongosolo sikumakwezedwa, ndipo gawo la chitetezo cha chitetezo nthawi zambiri limatchedwa valve yothandizira.

3, mu dongosolo, ntchito kuteteza actuator (monga yamphamvu) kapena zigawo structural pansi pa zochita za mphamvu amphamvu kunja si kuonongeka, mu nkhani iyi, valavu mpumulo, timatcha valavu overload.

4, monga valavu yochepetsera kupanikizika, njira yozungulira yochepetsera, kuchepetsa kupanikizika.

Mfundo yogwira ntchito ya valve yothandizira

1. Pump pressure PP ikukwera

2, kuposa 21.6MP

3, kuthamanga kwa mpope kukankhira mutu wokweza kuti mugonjetse mphamvu yamasika kukankhira mmwamba

4. Bowo laling'ono la plunger (lokha 0,5) limayamba kukhala ndi kutuluka kwa mafuta

5. Plunger imakankhidwira m'mwamba chifukwa cha kusiyana kwapakati pakati pa kutsogolo ndi kumbuyo (pansi ndi yayikulu ndipo pamwamba ndi yaying'ono)

6, kukakamiza mafuta kubwerera ku thanki

7, kuthamanga kwa pampu kumatsika mpaka 21.6
