Working principle

The power machine drives the rotor components on the dynamometer spindle to rotate synchronously through the coupling, which stirs the water in the working chamber. Because of the centrifugal force produced by rotor rotation and the effect of rotor pits, water produces strong water eddy current between the side shell and the rotor pit. It gives the shell a rotating moment, so that the torque of the power machine is transmitted from the rotor to the shell. The brake arm mounted on the shell will rotate at an angle, so that the brake force is transmitted to the tension pressure sensor connected with the brake arm through the electronic digital display device. Display the braking force.
The dynamometer controls the opening of butterfly valve by electric drainage valve or drainage actuator by automatic regulating device. The opening of butterfly valve is controlled by drainage actuator to change the pressure of water in the working chamber of dynamometer to change the absorption power. At the same time, the speed of dynamometer can be measured by the speed sensor and displayed on the electronic display instrument.
Because it is a pressure-controlled hydraulic dynamometer and adjusts the pressure of working chamber by changing the opening of butterfly valve, the whole process must be an automatic closed-loop control system, so the pressure YP dynamometer must be equipped with an electronic control cabinet with automatic control function to operate.
