Always device of excitation of electric machinery of synchronism of ball mill of cupreous choosing mill transforms a success

03 × 6.

The device of excitation of synchronous electric machinery of 4m ball mill, the " that all uses an entrance so advocate device of commutate of " of bridge of loop, fully control. Because fixed number of years of this installation service is long already (nearly 20 years) , part yuan parts of an apparatus is serious ageing, performance characteristics is reduced greatly, cannot provide function of very good safety, protection to ball mill is used of synchronous electric machinery normally, and production of 0 spare parts already was not had on the market at present, once device malfunctions, maintenance is relatively difficult, production will face very big loss. For this, ground of this factory much azimuth, much channel is active with home each manufacturer is contacted, final with Suzhou friend limited company of bright science and technology manages club, the " that uses its company production advocate unit of commutate of " of bridge of loop, half control is foreign to " " device undertakes transforming. The " after transforming advocate device of commutate of " of bridge of loop, half control, use 3 silicon controlled rectifier, relatively " advocate construction of plant of commutate of " of bridge of loop, fully control is more simple and easy, more facilitating personnel operation and safeguard, control is more accurate, dependability also increases greatly. With former entrance plant phase is compared, function also rises somewhat, have: Reduce electric machinery to start earlier concussion arteries and veins to spend; Cold conditions is in when destroying magnetism resistor moves normally; When electric machinery moves, controller can make flowing stability does not have electric machinery since the function characteristic such as concussion, can be opposite of ball mill run the protective function with rise better normally. The use that passes period of time checks, this device use result is favorable. It is reported, in the success device of excitation of synchronous to 1 ＃ ball mill electric machinery undertakes transforming hind, this factory is returned will this year second half of the year begins device of excitation of synchronous to 2 ＃ ball mill electric machinery undertakes transforming.
