Hydraulic pump-a hnathawh dan tur (work principle) .
Hydraulic pump kalpui dan hi "volume change" principle atanga siam a ni a: pump chhunga sealed working chamber periodic expansion leh contraction hian oil suction leh pressure process a ti zo vek a ni.
Oil suction stage: Working chamber volume a sang a, chamber chhunga pressure chu atmospheric pressure aiin a hniam zawk. Tank chhunga oil chu atmospheric pressure hnathawh hnuaia oil suction pipe hmangin working chamber chhungah a lut a;
Oil pressure stage: Working chamber volume a tlahniam a, chamber chhunga oil chu a hrual a, pressure a sang a, chu chu oil pressure pipe hmangin hydraulic system-ah a chhuak a, chu chuan a hnuaia components te chu hnathawhna hmunah a hruai lut a ni.
2, Hydraulic pump hrang hrangte thliar hranna leh a nihna .
Structural form atanga a lan dan chuan hydraulic pump hi a bik takin a hnuaia category hrang hrangah then a ni a, an hman theih scenario te hi performance inang lo vang a ni:
Gear pump .
Structure: Meshing gear leh pump casing pahnih atanga siam niin, oil hi gear meshing clearance volume thlak danglam hmangin a chhuak a, a discharge a ni.
A nihna: Structure awlsam, man tlawm, anti pollution theihna chak tak, mahse flow pulsation lian tak, pressure hniam (a tlangpuiin 20mpa aia tlem emaw, a tlukpui emaw), leh efficiency tlemte nei.
A hman dan: Low pressure system, agricultural machinery (tractor hydraulic lift), sakna hmanrua te tak te (loader steering system), lubrication system, etc. te.
Vane pump .
Structure: Rotor, stator, blades, leh distribution plate atanga siam, blade te chu centrifugal force hnuaiah stator chhung lam ah nghet takin an inzawm a, closed working chamber an siam a, volume change chu stator curve hmangin an ti thei a ni.
A mizia: Uniform flow rate, pulsation tlem, noise hniam, pressure hniam (a tlangpuiin 16-25mpa aia tlem emaw, a tlukpui emaw), mahse anti pollution ability chak lo (opil tihfai nana mamawh sang).

A hman theih: Medium voltage system, machine hmanrua (grinding machine, milling machine), injection molding machine (mold clamping leh injection drive), automotive hydraulic power steering, etc. te tana feed hydraulic system ang chi te.
Piston pump a ni a.
Structure: Plunger, cylinder body, leh distribution plate atanga siam niin, cylinder body-a plunger reciprocating motion hmangin working chamber volume chu a danglam a ni. Axial piston pump (cylinder axis nena parallel) leh radial piston pump (cylinder axis nena inmil perpendicular) ah then a ni.
Features: Pressure sang (31.5mpa thleng), efficiency sang, flow regulation awlsam, mahse complex structure, cost sang tak, leh oil tihfai nana mamawh sang tak tak.
A hman theih: voltage sang leh sang-Power system, construction machinery (excavator main pump), metallurgical machinery (rolling mill hydraulic pressing), lawng deck machinery (Cargo crane), etc. te.
screw pump .
Structure: Closed chamber chu active screw leh driven screw engagement hmangin a lo awm a, oil axial movement chu screw rotation hmangin a nawr a ni.
A nihna: Uniform flow rate, thawm hniam tak, dam rei lutuk, mahse pressure hniam (a tlangpuiin 4Mpa aia tlem emaw, a tlukpui emaw), complex structure.
Low-pressure leh low-noise environment, precision machine tool lubrication, hydraulic system auxiliary pump, etc. te tan hman theih a ni.
