Does any one tried this type of liquid resistance starter.

(OP)
we have a new air blower in our factory,it`s motor comes with a liquid resistance starter from china,aside talk i`m afraid from it coz it`s old fashion it`s brand name is(Shanghai Surpass Sun Electric),model no. is czyq-3000/12-ys web site of company is http://www.ljvideo.net.cn/eng/ProductShow.asp?ProductID=30
so if anyone tried this type tell me what`s his opinion about it.

RE: Does any one tried this type of liquid resistance starter.

Do not know about that brand. But liquid starters have been around for a long time. Reliable devices and usually no problems if used as rotor resistors.

Make sure that you get a correctly translated operation and maintenance manual. That is probably the most important thing.

Met this kind of starters back in the sixties and still see some installed at mining companies. It would be wise to get a few reference sites and talk to the people there.

RE: Does any one tried this type of liquid resistance starter.

Yup, I still run across new liquid rheostat resistors being used on wound rotors every now and then. It's an old technology but it's reliable and fairly simple for most people to understand.

These days, we typically install a soft-starter and a single step resistor (shorted out once running) on wound rotor motors if the motor is installed just to provide a higher/better starting torque.

 

RE: Does any one tried this type of liquid resistance starter.

Many of the European designs for car crushers (8 - 10,000 HP) using wound rotor motors currenty use the liquid rehostats. I have seen several new USA installations with these devices.
