High pressure solenoid valve need to meet what condition to work?

High pressure solenoid valve need to meet what condition to work? Chinese traders company Zhang Xiaoen pressure solenoid valve work what condition to be met. Large cross-sectional area of the valve, in order to completely fill the plunger cavity, even under the condition of high speed to ensure a reliable performance. Light weight, Exercise quality small) To reduce stress. Quickly switch to a precise measurement of fuel. Under the condition of high pressure to provide high-voltage electrical magnetic force in order to meet the load demand. High pressure solenoid valve is controlled by the modulation current, change the current to control the current of the high pressure solenoid valve must achieve steep signal edge to make the fuel injection quantity has high repeatability. In addition, ECU such control must be in pump and electromagnetic valve under the premise of the minimum power loss. For example, the control current low enough to meet such requirement. Therefore, when applying pressure current ( About A) Later, reduce the control current of solenoid valve, until to maintain current ( About A) 。 Through the current model ( Injection start signal) , pump control unit that can detect the electromagnetic moment of needle valve and seat contact. So accurately calculating oil start time, injection starting point also can be precisely controlled.
