Description
Technical field
The utility model relates to water system, especially a kind of constant pressure water supply system.
Background technology
In the manufacturing process of pigment production enterprise, needing supplies water guarantees production run; Part enterprise water supply volume every day is bigger in process of production, use be that normally the 125-100-400 large pump supplies water, generally accomplish that by two water pumps one opens one and is equipped with in process of production; Because the requirement of production technology; The moment flowed fluctuation is big, and a water pump can not satisfy production requirement at work often, has brought uncertainty to production run.
The utility model content
It is big that the purpose of the utility model solves the moment flowed fluctuation in water supply process of single pump exactly, the problem that influence is produced.
The technical scheme that the utility model adopts is: a kind of constant pressure water supply system, it is characterized in that it comprises some water pumps, accumulator, output channel and the frequency converter that is used to supply water, and water pump is communicated with the efferent duct deferent; The outlet of water pump is serially connected with valve, and accumulator is communicated with the efferent duct deferent, is fixed with pressure transmitter on the user side tube wall of output channel; Pressure transmitter is electrically connected with frequency converter; The outlet tube wall of accumulator is provided with pressure sensor, and pressure sensor is electrically connected with frequency converter, the pressure signal input converter at two places; Frequency converter is electrically connected with pump motor, and pump motor is realized rotating speed control through frequency conversion.
Adopt technique scheme, evenly change the supply frequency f of motor stator winding, the synchronous rotational speed of change motor that just can be level and smooth.Motor speed is slack-off, and shaft power is with regard to corresponding minimizing, and power input to machine also reduces thereupon, the energy-conserving action of pump variable frequency speed governing that Here it is.Rely on frequency control can reach purpose of energy saving, simultaneously frequency converter and the constant voltage control that can realize cooperating of miscellaneous equipment to supplying water.So not only can be energy-conservation, and stable, the safe operation of water system also had great significance.
In sum, the utility model beneficial effect is: the utility model has been realized constant pressure water supply through changing the frequency of motor, and energy-saving effect is arranged simultaneously, realizes stable, the safe operation of water system.
