德思宏雙向往復增壓器工作原理
X超大流量系列為雙向往復增壓,其工作原理如上圖所示
1、圖示這個狀態下，液控換向閥左側小面積反饋腔與P口接通，右邊大面積反饋腔經過反饋槽右與T口相通，這時候，液控換向閥將往右邊移動。
2、液控換向閥往右移動換向后，P口液壓油經過液控換向閥，達到增壓大活塞LP左腔，推動增壓大活塞LP往右邊移動，增壓大活塞LP右腔液壓油則經過液控換向閥后回到T口。增壓大活塞LP往右邊移動的同時，推動增壓小活塞HP2壓縮右邊高壓腔液體，提高壓力，再從HP口輸出。
3、當增壓大活塞LP移動到右邊后，反饋槽左將連通，液控換向閥右邊大面積反饋腔經過反饋槽左與P口接通，由于液控換向閥右邊反饋面積大于左邊反饋面積，這時候將推動液控換向閥往左邊移動。
4、液控換向閥往左邊移動到位后，增壓大活塞又開始往左邊運動，原理和之前一樣，使左邊輸出高壓。
如此往復左右運動，實現連續增壓。
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.
德思宏超大流量液壓增壓器X系列，具有以下特點。
The X series booser with extra large flow has the following characteristics:
1、內部集成換向，連續增壓，動作無死點。
Internal integrated direction valve, continuous pressurization,no stuck design.
2、雙向增壓，增壓速度快。
Dual-acting, fast charging.
3、壓力自動補償，當低壓壓力P與高壓壓力HP達到壓力平衡時候，增壓器停止動作，當高壓壓力泄漏導致壓力下降時，增壓器又開始動作，繼續補償泄漏壓力，實現永不掉壓。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，體積小，重量輕。High integration, small size and light weight.
5、輸出壓力高，輸出流量大。High output pressure and large output flow.
6、活塞與孔采用間隙密封，壽命長。The piston and the hole are sealed by gaps, the service life is long
