Balance relief valve is connected with the inlet pipeline of fire pump.
The operation principle of Hydraulic Power System of the present invention is：Water is divided into two bye-passes after fire pump is pressurized, wherein
One is supplied water directly to fire monitor, and another, by metering valve current limliting, after self-balancing pressure release pressure regulating valve, is given fire-fighting
Hydraulic giant supplies water；The effect of metering valve is limitation flow, avoids occurring that self-balancing relief valve discharge flow is excessive causes firearms feed flow
Insufficient situation；Gas boosting pump pressure is set as slightly below fire-fighting lance operating pressure, and self-balancing relief valve can be by disappearing
Anti- pump water inlet pipeline aerial drainage so that metering valve outlet pressure remains slightly above gas boosting pump pressure, this structure
Ensure that metering valve outlet pressure is consistently equal to fire-fighting lance operating pressure；Therefore, the present invention can be achieved a fire pump and provide two
Kind output pressure, for fire monitor, big flow fire-fighting lance purpose used at the same time.
Advantageous effect：The Hydraulic Power System of the present invention worked at the same time for fire monitor, big flow fire-fighting lance and existing
There is technology to compare to has the following advantages：
