Foreword
Y series hydraulic dynamometers are used electric drain valve control. That is, by changing
the valve opening to change the size of the absorbed power. Braking power range from 20KW to 5900KW, full range of domestic and foreign users according to their range of engine power to choose the right model to buy.
The product is mainly used to detect a variety of diesel, gasoline, motor and other power machine of effective power. Is a power machine characteristics test, test the efficiency of transmission machinery essential test equipment.
The basic product is a one-way test, user test for both two-way ordering, please request, our company has given special customization.

Dynamometer structure
Y-type hydraulic dynamometer mainly by body parts, body parts measured force, into the drainage components, calibration components, electric drain valve parts, auto-adjusting device composed of parts and lubricating parts. See Figure II (a), (b).
1. Body parts
Body parts is to use the dynamometer to absorb water, the main components of the effective torque power machine. Figure three (a), (b).
Power machine output mechanical energy into heat in here, by the absorption of water into the shell in the discharge away, a very small part by the dynamometer casing wall heat to the air.
Its simple structure from the one in the rolling bearing can swing on a rack in the shell an
d composed of the rotor on the spindle. Dynamometer rotor mounted on the spindle center, left and right side of the bearing shell and the shell were symmetrical around the rotor mounted on both sides, left and right side of the rotor shell pits and pit forming the working chamber. Shell around the bearing housing connected with bi-metal sleeve bushing play a role in both, also played a role in sealing water. Y1500, Y2500, Y3300, Y5900-type dynamometer in order to prevent water leakage from the gap sealed to prevent water from entering the bearing to ensure that the bearing life.
Shell has opened a drainage hole, so the bearing shell has opened a water hole, in order to ensure the entry of cold water and hot water discharge. Around the bearing housing has a overflow pipes, dump the water cycle through the overflow pipes of water thrown into the base after discharge.
Installed at both ends of the spindle taper coupling, speed gear with one side, through the speed sensor, spindle speed can be displayed in the digital display table.
