Thir trta NV08-20B krmilni ventil Hidravlični ventil navojnega ventila

Ventil za plin je ventil, ki nadzoruje pretok tekočine s spreminjanjem odseka ali dolžine plina. Ventil za plin in povratni ventil je mogoče kombinirati v enosmerni ventil za plin, tako da jih vzporedno povežete. Vzponuja za plin in enosmerni ventil za plin so preprosti ventili za nadzor pretoka. V hidravličnem sistemu kvantitativne črpalke se kombinirajo ventil za plin in reliefni ventil, da tvorijo tri sisteme za regulacijo hitrosti, ki se nahaja

First, hydraulic:1, the main pump (hydraulic pump), usually called the large pump, is to supply oil to the entire hydraulic system, in short, to produce pressure to provide action for the excavator.2, the pilot pump, generally for the gear pump, the current excavator pilot pump and the main pump are connected together to provide the pilot oil for the action of the excavator (that is, the oil required for the operation of the handle of the excavator).Second, the engine:1, the oil pump provides lubricating oil to the lubricating mechanism of the engine, so that the engine life is longer and the work is more stable.2, the hand oil pump, located in the engine fuel injection pump pan, in the low pressure oil circuit of diesel.3, injection pump, there are two kinds of electric injection and direct injection, to provide high pressure fuel for the engine action, so that the fuel into the Komora za zgorevanje cilindra.4, vodna črpalka, ki je običajno nameščena na koncu ventilatorja motornega motorja, vloga je zagotoviti hladilno vodo za sistem hlajenja motorja, tako da je mogoče krožiti proti zbrisu, da se zagotovi življenjska doba storitvenega motorja.
