The specific embodiment
As shown in Figure 1, the utility model comprises three-phase four-wire system power supply, frequency converter 1 and a plurality of vibrator 2, and the three-phase four-wire system power supply is by the input of main breaker QF1 connection frequency converter 1, and main breaker QF1 can protect frequency converter 1 when circuit abnormality.A live wire of three-phase four-wire system power supply also is connected with voltmeter by the input of ammeter connection frequency converter between two live wires of three-phase four-wire system power supply.Ammeter and voltmeter can show the electric current of frequency converter 1, the relevant information of voltage.The output of frequency converter 1 connects respectively the input of a plurality of vibrators 2, also is provided with control module between three-phase four-wire system power supply and the frequency converter 1.The operating frequency of vibrator 2 is between 90Hz-200Hz.
Described control module comprises contactor coil KM, the zero line of three-phase four-wire system power supply connects the TB end of frequency converter 1 by contactor coil KM and total stop button SB1 of being connected, the zero line of three-phase four-wire system power supply also connects the TC end of frequency converter 1 by warning device, warning device adopts alarm lamp D1.A live wire of three-phase four-wire system power supply is held by the TA that the total start button SB2 that often opens connects frequency converter 1, and the TA contact of establishing relay in the frequency converter 1 is common point, and during frequency converter 1 normal operation, TA-TB is normally-closed contact, and TA-TC is normally opened contact.The two ends of total start button SB2 are parallel with contactor the first normally opened contact KM1, are respectively arranged with the second normally opened contact KM2, the 3rd normally opened contact KM3 and the 4th normally opened contact KM4 of contactor 1 on three outlet lines that frequency converter 1 output connects.Frequency converter 1 function control common port CM holds by X1 end and the X2 that the first paragraph speed of often opening is selected button SB3 be connected with second segment to select button SB4 to connect frequency converter respectively, frequency converter function control common port CM leaves the FWD end that contact KM5 connects frequency converter 1 by 5 constant virtues of contactor, and frequency converter function control common port CM connects the RST end of frequency converter 1 by the SR SB5 that often opens.Be provided with branch breaker protection switch QF2 on the connection line of the output of frequency converter 1 and each vibrator 2.
As shown in Figures 2 and 3, be symmetrically arranged with the fixedly casting lug thereon 3 of vibrator 2 on the housing of vibrator 2, be provided with fixing hole 4 on the casting lug thereon 3.Fixing hole 4 is used for vibrator 2 is fixed to the template of making track plates.Be provided with O RunddichtringO 7 between the end cap 5 of vibrator 2 and the bearing block 6, also be coated with the fluid sealant that is useful on the isolated water steam between the end cap 5 of vibrator 2 and the bearing block 6.
The utility model in use, the staff presses total start button SB2, and when frequency converter 1 normal operation, TA-TB is normally-closed contact, contactor coil KM gets electric, and contactor first, second, third, fourth and fifth normally opened contact KM1, KM2, KM3, KM4 and KM5 are closed.Form self-locking when contactor the first normally opened contact KM1 is closed, contactor coil KM does not cut off the power supply when guaranteeing total start button SB2 disconnection; Second, third guarantees when closed that with the 4th normally opened contact KM2, KM3, KM4 each vibrator 2 gets electric work, has realized the integral body control of a plurality of vibrators 2 contactor; Assurance frequency converter 2 was enabled positive rotary-die type when contact KM5 closure was left in contactor 5 constant virtues.When the staff presses normally closed total stop button SB1, contactor coil KM outage, contactor first, second, third, fourth and fifth normally opened contact KM1, KM2, KM3, KM4 and KM5 disconnect, and each vibrator 2 outages quit work.If frequency converter 1 breaks down during work, this moment, normally-closed contact TA-TB disconnected, contactor coil KM outage, and each vibrator outage quits work; Simultaneously, normally opened contact TA-TC is closed, and alarm lamp D1 gets electric work, and prompting staff frequency converter 1 breaks down.
