SDHD 250-350KW 3500rpm ±0.2%FS 1500Nm+ AC Dynamometer for Diesel
Engine Test
Overview of SDHD/SDHD+ AC dynamometer
The host of AC dynamometer adopts seelong AC motor, and the torque
flange is installed on the power dynamometer for torque
measurement; the torque flange adoptsSEELONG tight torque flange.
The electric dynamometer includes air cooling device (fan), rotary
encoder and shaft temperature monitoring system. The motor bearing
adopts imported bearing; the speed signal is sent to the frequency
conversion drive cabinet through the bus, and the torque signal is
sent to the control system by the imported original shielded cable
to form a closed-loop control. At the same time, the speed and
torque values are stored, displayed, regulated and controlled in
the computer unit.
Each SeeLong Gasoline Engine Test System (SLH)is optimally designed
for categories of Gasoline engines.The SLH range of engine test
systems from SeeLong enables you to add dependable testing capacity
in the shortest possible time. All systems are supplied pre-tested
and pre-assembled on a mounting plate ensuring fast and reliable
installation on site without need for special foundations.The
modular design of the systems means that you do not have to
compromise on flexibility or choice.The systems have a wide range
of options, so that future upgrades are easily added to meet new
requirements.
