CY14-1B series pump is an axial piston pump with cylinder rotation and variable head (swash plate) variable. Due to sliding boots and variable between head, oil distribution plate and the cylinder body adopts hydraulic static equilibrium design of oil film thickness between the two surface of sport in the pure liquid friction under operation, and eliminating the heavy thrust bearing, and compared with other types of pump, has a simple structure, small volume, high efficiency, light weight, low noise, long service life, strong self-priming capacity, etc, It is suitable for hydraulic equipment such as forging machinery, machine tool, ship, aviation, metallurgical machinery, plastic machinery, engineering machinery and mining machinery.
Working Principle：
The main body (figure 1) is driven by the drive shaft to rotate the cylinder block, so that the seven plungers evenly distributed on the cylinder block rotate around the center line of the drive shaft, and the center spring presses the slipper in the column sliding assembly on the thrust plate (or swish plate), while the center spring presses the cylinder block on the oil plate through the jacket, which acts as the initial seal. In this way, the plunger reciprocates with the rotation of the cylinder to complete the oil suction and oil pressure action.
As shown in figure 1 of the pump pressure oil (> 5 mpa) by the channel (a), (b), (c) into the inferior vena (d) and variable shell when rod moves down, pushing the servo valve core movement, the (d) the oil in the cavity pressure channel (e) (g) into the cavity, promote variable piston moves down, the variable head rotated around the center of steel ball drive pin shaft rotation, Change the inclination Angle of variable head, so that the plunger stroke change, achieve the purpose of variable. On the contrary, the pull rod moves upward, the variable piston also moves upward, the variable head tilt Angle changes in the opposite direction, when the tilt Angle changes to 0°, the negative Angle changes, the oil flow is reversed, the pump's import and export exchange.
The hydraulic principle of the pump is shown in Figure 1-1, and the variable characteristics are shown in Figure 1-2. This pump is especially suitable for closed oil hydraulic system and frequent variable (each work cycle needs variable) open oil system, its manipulation can be used manual lever mechanism, CAM mechanism and cylinder, hydraulic cylinder and other ways.
