Excavator starting motor fittingsMachinery Parts Starting motor has a wide range of applications, simple structure, easy operation, easy maintenance, low cost, is currently widely used in Marine diesel engine, this starting device is a turbine form of motor, through the piston inside the drive small gear ring, thereby driving the diesel engine rotation. Of course, this starting device also includes pressure reducing valve, starting solenoid valve and other equipment. When the starting solenoid valve is opened, the 3MPa high pressure air supplied by the outside world passes through the self-configured pressure reducing valve to reduce the air pressure to about 1MPa. The air flows into the transmission box of the starting motor through the bypass pipeline, driving the pinion to slowly extend and engage with the flywheel tooth ring. When fully engaged, the high pressure air of the main circuit begins to enter the starting motor. Drive the internal piston, through the piston drives the internal turbine impeller to drive the pinion to rotate, the pinion then drives the meshing flywheel gear ring, flywheel gear ring drive flywheel, flywheel drive crankshaft, crankshaft drive piston up and down reciprocating movement, making the fuel burning under compression, thus helping the diesel engine to start successfully Excavator Parts The function of the starter is to use the starter to convert the electric energy of the battery into mechanical energy, and then drag the engine to start through the transmission mechanism.
Chassis Parts The starter is essentially a DC motor, the role is to drive the engine into the working state through the battery power supply, its performance directly affects and restricts the normal start of the car, so the working principle of the starter can be explained by the working principle of the main components of the DC motor. A DC motor is a device that converts electrical energy into mechanical energy. It is based on the principle that a charged conductor is subjected to the electromagnetic force in a magnetic field.
When the engine starts, the pinion on the starter shaft is inserted into the flywheel tooth ring to transfer the torque of the starter to the engine crankshaft; After the engine starts, the starter pinion and flywheel tooth ring can be automatically disengaged. The control device is also called the starter switch. The function of the control device is to connect and disconnect the circuit between the motor and the battery, and also to connect and disconnect the additional resistance of the ignition coil.
