将泵和阀组合成一体,并通过泵的旁通控制,使回路压力降至最低,从而减少管路及其泄漏。
Combine a body the pump and the valve, and through pump's by-pass governing, causes the return route pressure to drop to lowly, thus reduces the pipeline and divulging.
进入旁通管线的液体通过泵循环。
Fluid entering the by-pass line is recirculated through the pump.
为了避免螺杆泵损坏,一般会在螺杆泵出口处安装旁通溢流阀,用以稳定出口压力,保持泵的正常运转。
In order to avoid screw pump is damaged, usually installed in the screw pump bypass relief valve outlet to a stable outlet pressure, keep the pump running.
