The WZ series eddy current dynamometer is a precision and reliable product with a wide range of applications that can be tested in both directions. Users generally use it for high-level testing benches. With the increasing demand for test benches from users, more and more users are using eddy current dynamometers as factory tests.

The minimum power range of the WZ series eddy current dynamometer is 0-5kW, and the maximum is 1500kW.
The WZ series eddy current dynamometer has relatively high requirements for water quality. If the water quality is too hard, the cooling pipeline is prone to fouling, blocking the pipeline, and affecting the thermal effect of the dynamometer.
Requirements for Cooling Water for WZ Series Eddy Current Dynamometers
The heat generated by the eddy current of the eddy current dynamometer is mainly carried away by cooling water, which has good water quality. Generally, softened water is used, with a water pressure of 0.02-0.05MPa and a flow rate of 20 liters per kilowatt hour.
There are no special requirements for water pressure stability.
After a long period of use, the water temperature of the discharged water will increase, such as exceeding 65 ° C. If increasing the inlet water volume still cannot reduce the water temperature, it should be considered to use a deintering agent to treat the cooling pipeline of the dynamometer wall.
Selection principles and matching methods of supporting instruments for WZ series eddy current dynamometer
The load of an eddy current dynamometer is mainly changed by changing the current of the excitation coil. The size of the current is easy to control, so it can conveniently stabilize the load and have good control performance.
When ordering, users must order the DH2000 series control produced by our company, which can conveniently and reliably conduct various performance tests.
