X large flow series is dual-acting booster, and its working principle is shown in the above figure
1. In the figure, the small area feedback chamber on the left of the hydraulic control directional valve is connected with port P, and the large area feedback chamber on the right is connected with port T through the feedback tank. At this time, the hydraulic control directional valve will move to the right.
2. When the hydraulic control directional valve moves to the right , the hydraulic oil at port P passes through the hydraulic control directional valve to reach the left chamber of the large piston LP,
and pushes the large piston LP to move to the right. The hydraulic oil in the right chamber of the large piston LP returns to port T after passing through the hydraulic control directional valve. While the large piston LP moves to the right, push the small piston HP2 to compress the liquid in the high-pressure chamber on the right, increase the pressure, and then output it from the HP port.
3. When the large piston LP moves to the right, the left side of the feedback tank will be connected,and the large-area feedback chamber on the right side of the hydraulic control directional valve will be connected with port P through the feedback tank .Since the feedback area on the right side of the hydraulic control directional valve is greater than that on the left,it will push the hydraulic control directional valve to the left.
4. After the hydraulic control directional valve moves to the left in place, the large piston LP starts to move to the left again. The principle is the same as before, making the left output high pressure.Such reciprocating left and right movement realizes continuous pressurization.
The X series booser with extra large flow has the following characteristics:
Internal integrated direction valve, continuous pressurization,no stuck design.
Dual-acting, fast charging.
3、压力自动补偿，当低压压力P与高压压力HP达到压力平衡时候，增压器停止动作，当高压压力泄漏导致压力下降时，增压器又开始动作，继续补偿泄漏压力，实现永不掉压。Pressure auto-compensation, when the low pressure P and high pressure HP reach the pressure balance, the booster stops working, when the high pressure pressure leak causes the pressure to drop, the booster starts to operate again, continue to compensate the leakage pressure, to achieve never drop the pressure.
4、集成度高，体积小，重量轻。High integration, small size and light weight.
5、输出压力高，输出流量大。High output pressure and large output flow.
6、活塞与孔采用间隙密封，寿命长。The piston and the hole are sealed by gaps, the service life is long
