The characteristic of product:

The YCY series of high pressure hydraulic compensated variable displacement oil pump is a form of pressure by the pump itself, automatic control, as shown above high-pressure oil flow through the channel (a), (b), (c), enter the variable shell (302) of the Inferior Vena (d) thus through the channel (e) respectively into the channel (f) and (h), When the spring force is greater than the channel (f) into the servo piston (309) hydraulic thrust area of the bottom ring, then oil after ( h) into the cavity (g), to promote the variable piston (301) moves down, the pump flow increased.

High Pressure Hydraulic Compensated Variable Displacement Oil Pump

Conversely, when the pump pressure to overcome the spring force when the servo piston moving up and blocking access (h), so (g) the oil chamber by (i) the relief, this time moving piston variable pump flow decreases. YCY14-1B YCY high pressure hydraulic compensated variable displacement oil pump next diagram shows a variable pump characteristic curve, the shadow of that features its adjustment range.

The slope of AB is outside the spring (307) stiffness of the decision, BC's slope is outside the spring (307) and in spring (306) and stiffness of the decision, CD vary, depending on the location of limit screws (restrictions variable head tilt angle). Conditioning variable characteristics, the additional rule changes by A1B1C1D1 can screw screwed to the top of the first limit, then adjusting spring sets (305) to flow just change the pressure when the pressure in line with the A1 point, then adjust limit screws so that traffic flow will not change the pressure points with the D1 line of traffic, including inter-relation between pressure and flow are pre-designed, without adjustment, as long as the A1 and D1 two of the flow and pressure adjustment well, the pump to automatically change according to A1B1C1 curve. This variable type is similar to the characteristic curve changes in accordance with constant power.

The characteristics of high pressure hydraulic compensated variable displacement oil pump,the conversion points A1 and D1 of the parameters can be calculated as follows: For example: the process of known characteristics of the machine required a maximum pump pressure Pmax, Pmax when the D1 point in the flow of Q1, when the flow of low pressure pump as Qmax, the pump pressure in the A1 point: where: ηP1-pump P1 ηPmax-the overall efficiency of the overall efficiency of the pump in Pmax in this series pump, prime mover desirable ηP1/ηPmax ≈ 1 can press the power options Type: NH = Pmax · Q1/60η which η desirable 0.8-0.9 (when Q1 is small, whichever is less value, whichever is greater when larger.)
