Background technology
Existing freezer ammonia type compressor is directly start when starting, and equipment needed thereby is few, and Starting mode is simple, and cost is lower.But when starting, for motor, provide the circuit of power supply and transformer to be difficult to meet the condition directly started on the one hand, the powerful electric current produced when starting on the other hand can cause very large impact to electrical network and motor, affect the useful life of motor, unfavorable to the operation of electrical network.
Equipment operationally output torque is lower, and operating efficiency is not high.And during equipment appearance damage, motor can be caused thereupon to damage, cause difficulty to the maintenance of equipment, cause larger economic loss.The control device of existing equipment generally all concentrates on the control panel of electric cabinet, at the enterprising line operate of equipment, can only can not carry out Long-distance Control, very inconvenient.
Utility model content
The purpose of this utility model is the freezer ammonia type energy conservation of compressor transmission mechanism providing a kind of soft start and soft stop, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of freezer ammonia type energy conservation of compressor transmission mechanism, comprise control device, motor transmission part and moment of torsion clutch part, described control device is electric cabinet, be provided with soft initiator, thermal relay, contactor, transformer and control module in electric cabinet, described control module comprises long-distance metering meter-reading module, frequency conversion soft start and soft stop module and overcurrent and overvoltage protective module; Wherein long-distance metering meter-reading module all turns serial port module with TC/IP with frequency conversion soft start and soft stop module and is connected; Overcurrent and overvoltage protective module is connected with equipment control circuit; Control device is connected with motor transmission part by equipment control circuit, and motor transmission part is connected with moment of torsion clutch some mechanical; Motor transmission part comprises motor and gear box, and moment of torsion clutch part is divided and comprised limiter; The soft start and soft stop of frequency conversion soft start and soft stop module controls motor; Motor is driven by gear box and connects limiter.
As further program of the utility model: described soft initiator is 90kW soft initiator.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, by arranging frequency conversion soft start and soft stop module, the soft start and soft stop of motor can be realized, mechanical motor is played a protective role, avoid the quick overcurrent-overvoltage of motor take advantage of the waste of power load of carrying; Reduce motor and the unnecessary impact carried out when directly starting, add output torque simultaneously.Motor can not be damaged during device damage.User by the telemanagement software simulating of pc client to the remote control management of equipment.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 4, a kind of freezer ammonia type energy conservation of compressor transmission mechanism, comprise control device, motor transmission part and moment of torsion clutch part, described control device is electric cabinet 1, be provided with soft initiator 11, thermal relay 12, contactor 13, transformer 14 and control module in electric cabinet 1, described control module comprises long-distance metering meter-reading module, frequency conversion soft start and soft stop module and overcurrent and overvoltage protective module; Wherein long-distance metering meter-reading module all turns serial port module with TC/IP with frequency conversion soft start and soft stop module and is connected; Overcurrent and overvoltage protective module is connected with equipment control circuit; Control device is connected with motor transmission part by equipment control circuit, and motor transmission part is connected with moment of torsion clutch some mechanical; Motor transmission part comprises motor 2 and gear box 3, and moment of torsion clutch part is divided and comprised limiter 4; The soft start and soft stop of frequency conversion soft start and soft stop module controls motor 2; First pass through frequency conversion soft start and soft stop module to arrive fast speedup mode starter motor 2 slowly, moment of torsion also with control circuit from big to small, after in motor 2 rotating speed to setting range, soft opening automatically can jump to contactor 13 and enter normal work, can avoid motor 2 waste of power load to take advantage of year of overcurrent-overvoltage institute fast like this.Motor 2 is driven by gear box 3 and connects limiter 4.After motor 2 enters normal work, driven gear case 3 is exported balance by leverage, at this moment moment of torsion is delivered to limiter 4, limiter 4 at self moment of torsion is passed to the equipment needing to drive again in receptible scope, when being driven device damage, limiter 4 can automatic clutch.
Further, soft initiator 11 described in the utility model is 90kW soft initiator.
The utility model decreases the unnecessary impact caused when motor 2 directly starts, and adds output torque simultaneously.By the use of moment of torsion clutch part, prevent device damage from causing motor 2 also to damage, so three equipment components (electric cabinet, motor transmission part and moment of torsion clutch part) are indispensable.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technical scheme in each embodiment also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
