往复增压器

X超大流量系列为双向往复增压,其工作原理如上图所示
1、图示这个状态下，液控换向阀左侧小面积反馈腔与P口接通，右边大面积反馈腔经过反馈槽右与T口相通，这时候，液控换向阀将往右边移动。
2、液控换向阀往右移动换向后，P口液压油经过液控换向阀，达到增压大活塞LP左腔，推动增压大活塞LP往右边移动，增压大活塞LP右腔液压油则经过液控换向阀后回到T口。增压大活塞LP往右边移动的同时，推动增压小活塞HP2压缩右边高压腔液体，提高压力，再从HP口输出。
3、当增压大活塞LP移动到右边后，反馈槽左将连通，液控换向阀右边大面积反馈腔经过反馈槽左与P口接通，由于液控换向阀右边反馈面积大于左边反馈面积，这时候将推动液控换向阀往左边移动。
4、液控换向阀往左边移动到位后，增压大活塞又开始往左边运动，原理和之前一样，使左边输出高压。
如此往复左右运动，实现连续增压。
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.
德思宏超大流量液压增压器X系列，具有以下特点。
The X series booser with extra large flow has the following characteristics:
1、内部集成换向，连续增压，动作无死点。
Internal integrated direction valve, continuous pressurization,no stuck design.
2、双向增压，增压速度快。
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
