一种无储液箱增压系统及其控制方法
摘要：
本发明涉及一种无储液箱增压系统，其包括进液口、出液口、电磁阀、单向阀、气压泵、控制电路，在进液口和出液口之间设有并联的左管路和右管路作为冷却管道，在左管路的进液口端设有电磁阀Ⅰ和单向阀Ⅰ，在右管路的进液口端设有电磁阀Ⅱ和单向阀Ⅱ，在左管路和右管路的出液口端分别设有单向阀Ⅲ和单向阀Ⅳ，左管路和右管路均与气压泵连接，在气压泵与左管路和右管路之间分别设有电磁阀Ⅲ和电磁阀Ⅳ，所述控制电路控制电磁阀与气压泵的工作状态，所述电磁阀为常闭电磁阀，本系统能增大出液口压力、减少冷却系统中管路中液体储存。本发明还涉及一种无储液箱增压系统的控制方法。
摘要（英）：

The invention relates to a pressurizing system without a liquid storing box. The system comprises a liquid inlet, a liquid outlet, solenoid valves, one-way valves, a pneumatic pump and a control circuit; a left pipeline and a right pipeline which are connected in parallel are arranged between the liquid inlet and the liquid outlet to be used as cooling channels; a solenoid valve I and an one-way valve II are arranged at the liquid inlet end of the left pipeline; a solenoid valve II and an one-way valve II are arranged at the liquid inlet end of the right pipeline; an one-way valve III and an one-way valve IV are respectively arranged at the liquid outlet ends of the left pipeline and the right pipeline; the left pipeline and the right pipeline are both connected with the pneumatic pump; a solenoid valve III and a solenoid valve IV are respectively arranged between the pneumatic pump, the left pipeline and the right pipeline; the control circuit controls the working state of the solenoid valves and the pneumatic pump; the solenoid valves are normally-closed solenoid valves. With the adoption of the system, the pressure of the liquid outlet can be increased; liquid stored in the pipeline of a cooling system can be reduced. The invention further relates to a control method of the pressurizing system without the liquid storing box.
