Excavator PC120-6 huru pfuti huru yekuyamura vharuvhu 723-30-90400

Zvinoenderana nehunhu hwe hydraulic pombi, iyo hydraulic system inoshandiswa ne hydraulic excavator yakakamurwa kuita marudzi matatu: quantitative system, variable system, uye huwandu uye inoshanduka system.
(1) Quantitative system
Muhuwandu hwehuwandu hunoshandiswa ne hydraulic excavators, kuyerera kunoramba kuripo, ndiko kuti, kuyerera hakushanduki nemutoro, uye kukurumidza kunowanzogadziriswa ne throttling. Zvinoenderana nehuwandu uye musanganiswa fomu yemapombi emafuta uye maseketi mune yehuwandu system, inogona kupatsanurwa kuita imwechete pombi single loop, kaviri pombi single loop quantitative system, kaviri pombi kaviri loop quantitative system uye yakawanda-pombi yakawanda-loop quantitative system.
(2) Variable system
Mune inoshanduka sisitimu inoshandiswa mu hydraulic excavator, stepless speed regulation inoonekwa nekusiyana kwevhoriyamu, uye kune nzira nhatu dzekugadzirisa: inoshanduka pombi-huwandu hwemotor kumhanya regulation, quantitative pump-variable motor speed regulation, uye variable pombi-variable motor speed regulation. Iyo inochinjika sisitimu inogamuchirwa ne hydraulic excavator kazhinji inotora musanganiswa wepombi inoshanduka uye yehuwandu mota kuti ione isina nhanho shanduko, uye ese ari maviri mapombi uye maviri maseketi. Zvinoenderana nekuti iwo machinjiro emaseketi maviri ane hukama, anogona kupatsanurwa kuita marudzi maviri: sub-simba shanduko system uye yakazara simba shanduko system. Pombi yega yega yemafuta eiyo sub-power variable system ine simba rekudzora muchina, uye shanduko yekuyerera kwepombi yemafuta inongokanganiswa nekuchinja kwekumanikidza kwedunhu mauri, izvo zvisina chekuita nekudzvanywa kwe rimwe dunhu, ndiko kuti, pombi dzemafuta emaseketi maviri akazvimiririra anogara achigadzirisa masimba emagetsi, uye mapombi maviri emafuta ega ega ane bhaketi remagetsi ekubuda kweinjini; Mapombi maviri emafuta ari musimba rakazara rekuchinja masisitimu anoenzanirana neakazara simba rekudzora meshini, kuitira kuti swing Angle yemapombi maviri emafuta inogara yakafanana.
Iwo machinjiro ekuwiriranisa uye traffic zvakafanana. Chii chinosarudza kuchinja kwehuwandu hwekuyerera ndeyekumanikidza kwese kwehurongwa, uye simba remapombi maviri emafuta harina kufanana muhuwandu hwemhando. Iyo dhizaini yekudzora ine mafomu maviri emakanika yekubatanidza uye hydraulic yekubatanidza.
