Mehansko načelo črpalke na odprti osi

Skupna vzajemna poteza l bata bata bat je stalna in je določena z dvigom odmikača . Količina olja, ki ga dovaja bat na cikel Končni čas oskrbe z nafto in s tem spreminja količino dovoda nafte ., ko delovna črpalka deluje, odmik na odmični gredi in vbrizgavanje črpalke in bat silijo balo, da se vrti navzgor in navzdol, s čimer lahko opravite nalogo črpanja oljne črpalke . oljne črpalke razdeliti na dva dva namaza {5} lahko razdelite na dva dva na shodu {5} {5} {5}, lahko oljno črpalko
When the raised part of the cam turns over, the plunger moves downward under the action of the spring force, and a vacuum is generated in the upper space of the plunger (called the oil pumping chamber). When the upper end face of the plunger opens the oil inlet hole on the plunger sleeve, the diesel filled in the oil channel of the upper body of the oil pump enters the oil pumping chamber through the oil luknja in bat se premakne v spodnji mrtvi center, dovajanje nafte pa se konča .
The plunger supplies oil upward. When the plunger moves upward to the inclined groove (stop supply edge) on the plunger and communicates with the oil return hole on the sleeve, the low-pressure oil circuit of the pump oil chamber communicates with the middle hole and radial hole and inclined groove of the plunger head, and the oil pressure drops suddenly. The oil outlet ventil je hitro zaprt pod dejanjem vzmetne sile in oskrba nafte se ustavi . Po tem se bat spet premakne navzgor ., ko se dvignjeni del odmika prevrne, se bat spet premakne navzdol pod dejanjem pomladi .. plunger. There are two one-way valves on a plunger pump, and the directions are opposite. When the plunger moves in one direction, negative pressure appears in the cylinder. At this time, one one-way valve opens and the liquid is sucked into the cylinder. When the plunger moves in the other direction, the Tekočina je stisnjena, drugi enosmerni ventil pa se odpre, tekočina, sesano v valj
