Abstract
The utility model relates to a full automatic water supply device with variable pressure and adjustable speed, which is composed of a water pump, a pole changing multi-speed and three-phase asynchronous motor, a pressure sensor, a control cabinet, a regulation energy storage tank and a standby water pump. Because a water supply regulation system which is composed of the water pump and the regulation energy storage tank is driven by the pole changing multi-speed and three-phase asynchronous motor with square descending torque characteristics, which replaces the way that the water supply system of the water pump is driven by a common motor used at present, the utility model overcomes the disadvantages of low efficiency and high price of the original water supply device and is a new energy-saving water supply device.
Description
The utility model relates to a kind of supply equipment, particularly a kind of energy-saving full-automatic transformation speed governing type water supply facilities.
At present, life, production and fire water supply equipment are in order to satisfy the needs of water changes in flow rate, generally adopt water tower, high level cistern, air pressure tank, frequency control and set up the mode that water pump directly supplies water, but the consumption steel are many, power consumption is high owing to the upper type ubiquity, floor space is big, shortcomings such as valency is expensive are so should not promote.
The purpose of this utility model is to provide a kind of water supply facilities of energy-saving fully automatic operation, this water supply facilities promptly has good adjusting feedwater performance, guarantee water supply volume for a long time, water pump runs up, water supply volume after a little while, the water pump low-speed running, also have volume little, consume few, inexpensive, the advantage of simple structure of steel, can save a large amount of energy than similar water supply facilities when the more important thing is this water supply facilities operation.
Its concrete solution is: be directly proportional with the first power of rotating speed according to pump capacity; Square being directly proportional of lift and rotating speed; Cube relation that is directly proportional of power and rotating speed.Employing has square the successively decrease pole-changing multi-speed 3-phase asynchronous motor of torque characteristics of having of two or more rotating speed and drags water pump, this threephase asynchronous is according to the coupling requirement of pump head, flow, rotating speed and power, adopt the pole-changing multi-speed 3-phase asynchronous motor utilization to change the number of pole-pairs of motor winding and obtain two or more rotating speed and corresponding different mesh powers, the way of change winding number of pole-pairs has: 1. adopt the independent winding that is embedded with two different poles logarithms at stator slot; 2. the connection that changes stator winding realizes changing number of pole-pairs.Thereby regulate consumed power and water pump the consumed power during at low speed low lift low discharge of water pump when the high-lift big flow of high speed and reach energy-conservation purpose.According to the variation of pipe network water supply volume, adopt electric control gear to control the rotating speed of pole-changing multi-speed 3-phase asynchronous motor automatically in the real-world operation.The pipe network water supply volume for a long time, pressure descends, pole-changing multi-speed 3-phase asynchronous motor drags water pump and runs up, big flow supplies water.The pipe network water supply volume after a little while, pressure rises, the pole-changing multi-speed 3-phase asynchronous motor low-speed running, the water pump low discharge supplies water, thereby has regulated the motor wasted work, reaches purpose of energy saving.Because the pole-changing multi-speed 3-phase asynchronous motor that drags water pump turns round continuously, thus during speed governing the electric current of pole-changing multi-speed 3-phase asynchronous motor change steady, thereby prolonged life-span of water pump and motor.In order to reduce water pump and the frequency that drags its pole-changing multi-speed 3-phase asynchronous motor rotation speed change, one small-sized adjusting water pot can be set at the pump outlet place, adopt the air pressure tank energy storage principle, when water pump runs up, store the unnecessary water yield, supply water when adding to the water pump low-speed running.
The control of water pump, pole-changing multi-speed 3-phase asynchronous motor generally adopts A.C. contactor-relay system to control, and also can adopt the bidirectional triode thyristor alternating-current switch to control.Water pump can adopt centrifugal pump, submersible pump, deep well pump, tubing pump.
The utility model has the advantages that: adopted pole-changing multi-speed 3-phase asynchronous motor to drag water pump with the torque characteristics that square successively decreases, utilize ductwork pressure to change and regulate pump capacity, be aided with and regulate water pot energy storage adjusting output, and adopt automaton to control, thereby has simple in structure, inexpensive, good, the energy-saving advantages of adjusting capacity of water supply.
