Abstract
The utility model relates to a pressure resistance regulating type automatic speed-changing water supply device. A pressure resistance regulator is connected between a control box and a water pump. The front of a damping tube is connected with a dynamic and static pressure reducing valve. The damping tube is connected between the dynamic and static pressure reducing valve and a hollow pressure spring tube. The action of the spring tube drives the action of a connecting rod, so that the push and pull movement of a pendulum gear drives a gear shaft to move reciprocally, and a regulable resistor rotates. A pivot point serves as the center of the connecting rod. Electrical signals pass through a frequency variable pulse source, a pulse circular dispenser and a three-phase inverter, so as to achieve that the rotation number of the water pump is changed along the change of pressure. Therefore, the pressure is basically kept on a determinate constant. By using the S-shaped hollow pressure spring tube, the utility model enlarges the amount of expansion and contraction under the condition of same pressure.
Description
The utility model belongs to the technological improvement of automatic water supply equipment.
The domestic water supply facilities that generally adopts is a water tower equipment at present.China each department great majority are this way of supplying water before 10 years.Owing to build factors such as investment is big, sanitary condition difference,, generally do not adopt now except that high-order pondage is had the special requirement.Produced pneumatic installation water supply thus.Automatically there is the secondary pollution of water quality in gas compensating type, can not drop into immediately after the power failure, and there is gas leakage in diaphragm type, and glued membrane is aging, and the life-span is short, and all exists regulating pondage little, and steel consumption is big, and floor space is big, shortcomings such as cost height.Microcomputer control speed governing self water feeding: overcome above-mentioned shortcoming, saved power consumption again.But owing to used many electronic original parts, and higher to temperature, the humidity requirement of environment, especially under pump house or other adverse circumstances, its operational reliability has just reduced.Moreover all microcomputer governing water supply installations all exist complex structure, cost height, have also increased line pipe reason expense and maintenance difficulty simultaneously.
The purpose of this utility model is to provide that a kind of a kind of cost that can overcome above-mentioned deficiency is low, simple in structure, the pressure rheostatic fluid drive water supply facilities of good reliability.
The purpose of this utility model is achieved in that and is connected to the pressure resistance regulator between control cabinet and water pump, and variable frequency clock, pulse ring distributor, three circuit boards of three-phase inverter are housed in the control cabinet.The pressure resistance regulator is made up of hollow pressure bourdon tube, connecting rod, fulcrum, pendulum tooth, tooth axle, adjustable resistor, damper tube, dynamic and static pressure reducing valve, counterweight; Before damper tube, be connected to the dynamic and static pressure reducing valve, be connected to damper tube between dynamic and static pressure reducing valve and the hollow pressure bourdon tube, the action drive of hollow pressure bourdon tube is that the action of the connecting rod at center makes pendulum tooth push-and-pull campaign drive the reciprocating motion of tooth axle with the fulcrum, and adjustable resistance rotates.The hollow pressure bourdon tube can make the question mark shape or for increase sensitivity make S shape several.
The utlity model has following advantage: when system pressure was less than or equal to setting pressure, it was nought state that the position of pressure resistance regulator is in the adjustable resistance value, and water pump is worked under the design rated revolution.When system pressure during more than or equal to limiting pressure, the adjustable electric resistance is a constant, and then the water pump revolution is a minimum value.When system pressure descended, the pressure resistance regulator moved again, and the adjustable electric resistance reduces, and the water pump revolution improves.Tend towards stability at last, the water pump revolution is the function of pressure.Feed pressure is changed in the 0.04MPa scope all the time, and frequent thereby wall has been exempted from starting mode of pump, power consumption reduces greatly.
Be described further below with reference to accompanying drawings, and embodiment is provided.

1 → variable frequency clock, 2 → pulse ring distributor, 3 → three-phase inverter, 4 → water pump, 5 → lower water box, 6 → water level controller, 7 → pressure resistance regulator, 8 → control cabinet, 9 → hollow pressure bourdon tube, 10 → connecting rod, 11 → fulcrum, 12 → pendulum tooth, 13 → tooth axle, 14 adjustable resistors, 15 → damper tube, 16 → dynamic and static pressure reducing valve, 17 → counterweight, C → relay, Y → input line, N → water input.
Between control cabinet and water pump, be connected to the pressure resistance regulator, variable frequency clock, pulse ring distributor, three circuit boards of three-phase inverter are housed in the control cabinet, and the pressure resistance regulator is made up of hollow pressure bourdon tube, connecting rod, fulcrum, pendulum tooth, tooth axle, adjustable resistor, damper tube, dynamic and static pressure reducing valve, counterweight.Being connected to the dynamic and static pressure reducing valve before damper tube, being connected to damper tube between dynamic and static pressure reducing valve and the hollow pressure bourdon tube, is axle with the fulcrum, connecting rod one termination pendulum tooth, and the hollow pressure bourdon tube is question mark shape or S shape.Connecting rod and counterweight, the end of hollow pressure bourdon tube connects with bolt or screw, and it is the motion of the connecting rod at center that the action of hollow pressure bourdon tube drives with the fulcrum.Make pendulum tooth push-and-pull campaign drive the tooth axle and move back and forth, adjustable resistor rotates.
Water in lower water box enters the dynamic and static pressure reducing valve by the work of water pump through N, damper tube, during the hollow pressure bourdon tube, hollow pressure bourdon tube inner fluid increases (or minimizing) pressure, hollow pressure bourdon tube just distortion is upheld (or contraction), end at the hollow pressure bourdon tube, fulcrum by connecting rod is the center, draw (or pushing away) movable pendulum tooth, the tooth axle is moved back and forth, adjustable resistor is rotated, the resistance that increased (or minimizing), the change in resistance of adjustable resistor, by output line Y it is sent into to control cabinet, the variation of pressure resistance regulator has caused the frequency change of variable frequency clock, thereby the variable pulse of output frequency inputs to six shaping power amplifiers (1CF～6CF), six pulse ring distributors that controllable silicon is formed have realized that the revolution of water pump changes along with the variation of water pressure, and pressure can be remained on definite constant.The water level controller of the utility model dress is when the low level cistern middle water level drops to minimum, and relay C is disconnected, and water pump just quits work, when treating that water level rises to certain altitude, water pump is just started working, in order to avoid drained because of water in the water tank, pump motor idle running burns out motor.Use the hollow pressure bourdon tube of S shape or the hollow pressure bourdon tube of several S shapes, under the identical situation of pressure, increased stroke.
