Abstract
The utility model relates to a centrifugal speed controller, which is composed of flywheels, a flyweight, a pull rod, a balancing spring and a control switch, is connected with a rotating shaft and rotates with the rotating shaft. When the rotation speed is more than or less than the rated rotation speed, the flyweight displaces under the action of increase and decrease of centrifugal force. So a microswitch is pressed to control an operation device. Accidents can be avoided. The utility model can be suitable for all electric mechanical devices with rotation devices.
Description
The utility model is that a kind of automaton of controlling rotating speed particularly relates to a kind of centrifugal revolution speed control device.
In the prior art; electric heating protective devices such as various overcurrent protective devices, electrothermal relay, air break protector can be found everywhere; they are Control current, voltage merely generally; shield to electric wiring, motor and by the machinery of electrical equipment control; for example when overwork, play the auto-cutout effect; these all can not play autoregulation, normal operation that promptly can not direct control mechanical electric equipment.
The utility model is on the basis of the common feature of similar various protectors; utilize the principle of existing centrifugal speed measuring device; improve; make the utility model not only play the function of above-mentioned various protectors; and again can automatic shutdown circuit when surpassing or being lower than certain rotating speed or control load automatically; make equipment continue to run well, avoid accident to take place or parking.
The principle of work of this utility model is, when the flyball on being fixed on rotating shaft rotates with rotating shaft, because different rotating speeds produces different centrifugal force, make the spring that cooperates with it be subjected to corresponding pulling force and produce displacement, thereby press the microswitch that is set on the certain position, control normal operation electric, plant equipment.
Figure one is a kind of structure of utility model, and now contrast figure one is described further:
1 axis hole, 2 spring tension adjusting levers, 3 balancing springs, 4 pull bars, 5 hypervelocity control depression bars, 6 normal letter control normally closed interlocks, 7 hypervelocity letter control normally open contacts, 8 flyballs, 9 power supply input switches, 10 power supplys output control binding post, 11 power supply lead-in clamps, 12 low speed letter control switch, 13 hypervelocity letter control switches, 14 low speed control depression bar, 15 low speed letter control switch normally closed interlock, 16 low speed letter control switch normally open contact, 17 input power source brush, electricity ring, 18 flywheels, 19 out-put supplies electricity ring, brush, 20 shells, 21 wiring are closed.
Rotating shaft is inserted in the axis hole 1, and makes it to be connected as one securely, when rotating shaft is turned round, makes the also rotation together thereupon of this controller.When equipment ran well, low speed letter control switch 12 and 13 liang of groups of hypervelocity letter control switch contact 15,6 were in normally off respectively, output rated speed signal power source.
When the equipment rotating speed surpasses rated speed, the centrifugal force of flyball 8 increases, balancing spring 3 elongations, hypervelocity control depression bar 5 just moves up, press hypervelocity letter control switch 13, hypervelocity letter control switch normally closed interlock 6 is disconnected, cut off the power supply that is connected on normal signal, hypervelocity letter control switch normally open contact 7 is connected simultaneously, thus maneuver control device.
When rotating speed descends suddenly, when being lower than rated speed, flyball centrifugal force reduces, balancing spring shortens, and low speed control depression bar 14 moves down, and presses low speed letter control switch 12, low speed letter control switch normally closed interlock 15 disconnects, cut off the normal signal power supply, low speed letter control switch normally open contact 16 is connected maneuver control device simultaneously.
The method that power supply input, output connect is, there is nine roads electricity ring 17 side of flywheel 18, respectively with two letter control switches 12,13 on eight contacts and of power supply input switch 9 decide contact and be connected.Be positioned on the shell 20 that parallels with the side that the electricity ring is housed of flywheel 18 with nine supporting brushes 19 of electricity ring, electricity ring, brush can contact with each other during flywheel 18 rotations, nine brushes are controlled binding post 10,11 connections of power supply lead-in clamp with power supply output respectively, and nine roads electricity ring believes that with low speed, hypervelocity eight contacts controlling switch 12,13 connect appropriate respectively.
Figure two is centrifugal rotational speed governors of another kind of frame mode, and its principle is identical substantially.When rotating speed increased or reduce, the centrifugal force of flyball 8 increased, and made the increase of flyball 8 opening angles or reduced drive letter control switch motion, thereby maneuver control device.
Claims (2)
1, a kind of centrifugal rotational speed governor, include flywheel 18, flyball 8, pull bar 4, balancing spring 3, control depression bar 5,14 is housed on the pull bar 4 that it is characterized in that linking to each other with flyball 8, two letter control switches 12,13 are housed on the flywheel 18, with electricity ring 19, brush 17 is housed on the shell 20.
2, according to claim 1, described controller is characterized in that letter control switch the 12, the 13rd, and Cheng Kaiguan is drawn in fine motion, and its contact 6,7,15,16 is connected with conducting ring 19, the brush on the shell 20 on the flywheel 18 respectively.
