The screw rod aerostatic press energy-saving drive controller of operation.
Background technology
Because screw rod aerostatic press has the advantages that efficiency high, long lifespan, noise are small, blowout is entered in its consumption of gas field processed
Formula developing stage.In order to realize that air pressure is controllable, break-make mode is control mode the most cheap, and is still now absolute main flow
Working method.Briefly this mode is to drop to lower limit screw rod aerostatic press in pressure at expulsion to start loading, and reaches pressure
Upper limit screw rod aerostatic press stops loading.Usual small-power screw rod aerostatic press can be controlled using the start-stop of directly contact device, and bigger work(
The meeting of rate carrys out tapping mode screw rod aerostatic press start-stop using step-down modes such as star/triangle, bypass type soft start, string reactance.Due to
These modes have one or more contactors, and the contact of contactor easily occurs arcing in break-make, cause contact to be glued
Even, the life-span is very short, so being not suitable for the frequent start-stop operating mode of screw rod aerostatic press.So the screw rod aerostatic press larger for power, is
Realize that gas pressure is controllable, do not shut down generally after electric motor starting, the break-make by valve carrys out control pressure.When this mode motor is long
Between be operated in power factor very low no-load state, bring unnecessary waste of energy.And in loading procedure, main motor is in advance
Without total head output.These starting equipments must coordinate the dedicated control device could to realize the automatic control to screw rod aerostatic press simultaneously
System, electric loop is complicated, with high costs.So developing a kind of suitable frequent start-stop of screw rod aerostatic press, the no-load running time is reduced,
And the fully automatic energy-saving screw rod aerostatic press drive control device of reactive power can be reduced with very considerable economic benefit.
