SHD520-2000/5000 long service life hydraulic dynamometer
Product discribtion
High-reliability and wide range application
Magnetoelectric speed sensor to achieve high precision instantaneous speed measurement
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.
