What is a turbocharger? It is an exquisite air compressor installed on the exhaust pipe of the engine. It uses the exhaust gas discharged from the engine to drive the turbine in the turbine chamber to rotate, and the turbine drives the coaxial impeller to rotate. The air is compressed and pressurize......

Excavator hydraulic motor is a device that converts the pressure energy of liquid into mechanical energy. In principle, a hydraulic pump can be used as a hydraulic motor, and a hydraulic motor can also be used as a hydraulic pump. But in fact, although the same type of hydraulic pump and hydraulic m......

How to check whether the grader variable speed solenoid valve is good or bad: first connect the controlled medium (liquid, gas and air with pressure, the pressure value is the middle value of the solenoid valve's operating pressure range) to the solenoid valve, and then energize the solenoid valve c......

The motor is the electric motor and the engine. The working principle is that the energized coil is forced to rotate in the magnetic field to drive the starter rotor to rotate, and the pinion on the rotor drives the engine flywheel to rotate.

Let's learn the steps and precautions of how to replace the excavator flywheel teeth

The excavator computer board (controller) is called the "brain" that controls the machine, and plays a vital role in the normal operation of the excavator. The computer board is like our human brain, it will collect various sensor information. Compare, calculate, and process the output, control the ......
