Type: Vehicle diesel engine fuel injection pump according to their works can be divided into a plunger-type injection pump, fuel pump - injector and injection pump piston pump rotor distribution pumping principle has cut cylindrical surface of the plunger head chute, and through radial holes, and the top axial bore communicating with the aim of changing the amount of circulating oil; plunger has put into the system, back to the oil 孔华东 diesel wholesale, are connected with the low-pressure oil chamber on the pump body, After the plunger into the pump upper body suit, the application of positioning screw positioning. Plunger head chute different location, change the amount of oil by different methods. The oil valve and the oil valve seat is also a pair of precision coupling, paired grinding are not interchangeable, the oil valve is a one-way valve, the spring pressure, the upper conical valve seat surface and tight fit, and its role is When the stop for the upper end of the high pressure tubing and the plunger cavity isolated to prevent the oil from flowing back into the high-pressure tubing inside the fuel pump. The function of the rectifier bridge (also known as rectifiers) rectifier bridge is a three-phase alternating current to the stator windings into direct current output. Rectifier by the rectifying plate, and the excitation diode rectifier diode. Diode only allows current way through, so it makes when it is connected to AC circuit current in the circuit by only one-way flow of so-called "rectification." Rectifier diode having a one-way conductivity of semiconductor devices, capable of AC power into DC power. AC power rectifier diodes become known as direct current rectifier diode, rectifier diodes are divided into positive and negative tube tube two kinds East China diesel engine, respectively press-fit (or welding) in two mutually insulated panel composed. Positive diode diode cathode center lead the East China diesel prices, the housing is negative. Positive diode housing press-fit or welding element plate, composed positive generator by a rear cover insulating the element plate bolt through to the enclosure, the nail becomes B + output of the generator. East China diesel engine manufacturer, East diesel, Weifang Huadong Huadong by Weifang Huadong Diesel Engine Co., Ltd. Weifang Huadong Engine Co., Ltd.
