Abstract
The utility model relates to an energy-saving power supply system of a concrete pipe pile production device. The energy-saving power supply system comprises a power supply and a plurality of electric devices and is characterized by further comprising a frequency converter and a programmable controller, wherein a voltage input end of the frequency converter is connected with the power supply, a voltage output end of the frequency converter is connected with the plurality of electric devices in parallel, and control contacts of the programmable controller are arranged between each electric device and the frequency converter. All the electric devices share the same frequency converter so that the overall cost can be reduced; and meanwhile, overload operation of the frequency converter caused by the fact that the electric devices run simultaneously can be avoided under the control of the programmable controller, and stable and reliable operation of the electric devices can be guaranteed.
Description
Technical field
The utility model relates to a kind of pile tube production equipment electric power system, particularly a kind of concrete tubular pile production equipment energy conservation and power supply system.
Background technology
Along with the development of concrete technology, the technology of concrete tubular pile also reaches its maturity, and except being applied to industry, covil construction, also is widely used in each field such as bridge, harbour, railway or hydraulic engineering.Steel tube concrete pile is owing to having advantages of steel-pipe pile and concrete tubular pile simultaneously, and obtains using more and more widely.
When carrying out the production of concrete tubular pile, need through feeding, stretch-draw, the operations such as centrifugal, normal temperature is steam-cured, put, the demoulding and a high-pressure steaming and cultivating, each operation need be applied to corresponding consumer.Frequency converter is widely used in each consumer, and it can realize soft start, frequency control, raising running accuracy, change power factor, the overcurrent/overvoltage/functions such as overload protection to AC induction motor.And the mode of using at present frequency converter all adopts one to one form, i.e. corresponding frequency converter of consumer, its shortcoming is: cost is high, and business burden is heavy, can't satisfy simultaneously a consumer and be equipped with a frequency converter, so some equipment then can't use frequency converter.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of concrete tubular pile production equipment energy conservation and power supply system of totally cost.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of concrete tubular pile production equipment energy conservation and power supply system, comprise power supply and several consumers, its innovative point is: also comprise frequency converter and Programmable Logic Controller, the voltage input end of described frequency converter is connected with power supply, the voltage output end of frequency converter several consumers in parallel all arrange the control contact of Programmable Logic Controller between described each consumer and the frequency converter.
The utility model has the advantage of: each consumer shares a frequency converter, can reduce holistic cost, simultaneously, avoids consumer to work simultaneously by Controlled by Programmable Controller and causes the frequency converter overload operation, guarantees that consumer is stable, reliability service.
Description of drawings
Fig. 1 is the utility model concrete tubular pile production equipment energy conservation and power supply system schematic diagram.
Embodiment
As shown in Figure 1, comprise power supply 1, frequency converter 2, consumer 3, Programmable Logic Controller 4, control contact 5.
The voltage input end of above-mentioned frequency converter 2 is connected with power supply 1, and the voltage output end of frequency converter 2 is parallel with several consumers 3, is provided with the control contact 5 of Programmable Logic Controller 4 between each consumer 3 and the frequency converter 2.
During use, if consumer 3 needs energising, control the control contact 5 of each consumer 3 by Programmable Logic Controller 4 closed or disconnect, so that when satisfying rated load at one time and requiring, open the consumer 3 of respective numbers.Guarantee that consumer is stable, reliability service.
