往復(fù)增壓器

X超大流量系列為雙向往復(fù)增壓,其工作原理如上圖所示
1、圖示這個(gè)狀態(tài)下，液控?fù)Q向閥左側(cè)小面積反饋腔與P口接通，右邊大面積反饋腔經(jīng)過(guò)反饋槽右與T口相通，這時(shí)候，液控?fù)Q向閥將往右邊移動(dòng)。
2、液控?fù)Q向閥往右移動(dòng)換向后，P口液壓油經(jīng)過(guò)液控?fù)Q向閥，達(dá)到增壓大活塞LP左腔，推動(dòng)增壓大活塞LP往右邊移動(dòng)，增壓大活塞LP右腔液壓油則經(jīng)過(guò)液控?fù)Q向閥后回到T口。增壓大活塞LP往右邊移動(dòng)的同時(shí)，推動(dòng)增壓小活塞HP2壓縮右邊高壓腔液體，提高壓力，再?gòu)腍P口輸出。
3、當(dāng)增壓大活塞LP移動(dòng)到右邊后，反饋槽左將連通，液控?fù)Q向閥右邊大面積反饋腔經(jīng)過(guò)反饋槽左與P口接通，由于液控?fù)Q向閥右邊反饋面積大于左邊反饋面積，這時(shí)候?qū)⑼苿?dòng)液控?fù)Q向閥往左邊移動(dòng)。
4、液控?fù)Q向閥往左邊移動(dòng)到位后，增壓大活塞又開(kāi)始往左邊運(yùn)動(dòng)，原理和之前一樣，使左邊輸出高壓。
如此往復(fù)左右運(yùn)動(dòng)，實(shí)現(xiàn)連續(xù)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(diǎn)。
The X series booser with extra large flow has the following characteristics:
1、內(nèi)部集成換向，連續(xù)增壓，動(dòng)作無(wú)死點(diǎn)。
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(dòng)補(bǔ)償，當(dāng)?shù)蛪簤毫與高壓壓力HP達(dá)到壓力平衡時(shí)候，增壓器停止動(dòng)作，當(dāng)高壓壓力泄漏導(dǎo)致壓力下降時(shí)，增壓器又開(kāi)始動(dòng)作，繼續(xù)補(bǔ)償泄漏壓力，實(shí)現(xiàn)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(zhǎng)。The piston and the hole are sealed by gaps, the service life is long
