Description
Technical field
The utility model relates to a kind of pump energy saving arrangements for speed regulation.
Background technique
At present, water pump generally carrys out type selecting according to the work unit power demand under state of operating at full capacity.In real work situation, water pump is not always under full load condition, to move conventionally, therefore needs to change pump capacity and adapts to actual demand.Variable-frequency control technique is current application pump energy saving speed adjusting technique the most widely, although this arrangements for speed regulation make motor carry out speed governing according to the flow of water pump, but frequency variator belongs to electrical equipment, need larger installing space, and can produce Harmfulness Caused by Harmonics, maintenance cost is also higher, and frequency variator can not move under the low speed, and speed adjustable range is influenced.
Model utility content
The purpose of this utility model is to overcome above defect, provide a kind of simple in structure, installing space is little, the pump energy saving arrangements for speed regulation of easy care, speed-regulating range width.
The technical solution of the utility model is: a kind of pump energy saving arrangements for speed regulation, it comprises motor, water pump, flow transducer, also comprise permanent-magnet speed governor, torque sensor, single-chip microcomputer, the mechanical input end of permanent-magnet speed governor is connected with motor output end, the mechanical output terminal of permanent-magnet speed governor is connected with one end of torque sensor, the other end of torque sensor is connected with water pump, flow transducer is for the flow of Real-Time Monitoring water pump, the dtc signal of torque sensor and the flux signal of flow transducer pass to single-chip microcomputer, permanent-magnet speed governor is connected by signaling line with single-chip microcomputer, single-chip microcomputer passes to permanent magnet speed regulation device by speed-regulating signal by the dtc signal receiving and flux signal after by computing, real-world operation rate signal is fed back to single-chip microcomputer by permanent magnet speed regulation device simultaneously.
For easy to adjust, also comprise remote controller, described remote controller and single-chip microcomputer are by wireless connections, and remote controller is long-range gives single-chip microcomputer sending controling instruction, and the Operational Limits of Real-Time Monitoring single-chip microcomputer.
Technique effect of the present utility model is: permanent-magnet speed governor is connected by signaling line with single-chip microcomputer, and according to the instruction of single-chip microcomputer, permanent-magnet speed governor self adaption regulates the output torque of motor, thereby realizes the control of load output speed, reduces energy consumption of electrical machinery.Permanent-magnet speed governor belongs to mechanical device, and the installing space needing is little, and environment, without harm, can realize electrodeless stepless speed control, and speed adjustable range is large.
