Fig. 2 is elevation of the present utility model;
Fig. 3 is lateral view of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
See shown in Fig. 1 to 3, a kind of periodical feeding device described in the utility model one preferred embodiment, comprise outlet pipe 1 and return pipe 2 that head and the tail docking forms closed circuit, outlet pipe 1 is successively by docking with return pipe 2 after cooling system 12 and pumping plant unit 13, pumping plant unit 13 comprise three with the pumping plant machine 14 be arranged in parallel, water inlet end and the water side of every platform pumping plant machine 14 are provided with water regulating valve 15.The water inlet end of return pipe 2 be disposed with hydraulic pressure in instruction return pipe 2 the first pressure meter 91, control discharge size in return pipe 2 electric flow control valve 7 and for feeding back described return pipe 2 flow information to control the flow transmitter 8 of described electric flow control valve 7 aperture.Return pipe 2 also on be arranged in parallel feed pump branch road and secondary water pump branch road, feed pump branch road and secondary water pump branch road be respectively arranged with feed pump 51 and be positioned at above feed pump 51 and the mair motor 41 driving it to operate, secondary water pump 52 and to be positioned at above secondary water pump 52 and the auxiliary-motor 42 driving it to operate, the water inlet end of feed pump 51 and secondary water pump 52 and water side are provided with water control valve 16.Return pipe 2 between feed pump branch road and secondary water pump branch road is also provided with the steady-flow tank 3 in order to stationary flow amount.Be disposed with for feeding back in described outlet pipe 1 hydraulic pressure to control the pressure sensor 10 of motor speed and the second pressure meter 92 in order to indicate hydraulic pressure in water pipe 1 at the water inlet end of outlet pipe 1.This periodical feeding device is also provided with switch board 6, switch board 6 is provided with the holding wire 11 be connected with electric flow control valve 7, flow transmitter 8, auxiliary-motor 42 and pressure sensor 10 respectively.
Operating principle of the present utility model is as follows: the cooling water in outlet pipe 1 exports in the cooling water pipeline of the pumping plant machine 14 run rear inflow pumping plant unit 13 from cooling system 12, the pumping plant machine 14 do not run can cut out the water regulating valve 15 of water inlet end and water side, to reach the object of water saving.Be arranged on the flow transmitter 8 of return pipe 2 water inlet end in order to detect the discharge in return pipe 2, and transmit water flow signal by holding wire 11 to switch board 6, switch board 6 passes through holding wire 11 signal transmission to electric flow control valve 7 according to flow transmitter 8 feedack, control the aperture of electric flow control valve 7 thus make the discharge in return pipe 2 meet switch board 6 setting value, reaching energy-conservation object.Feed pump 51 in this device is in running status usually, when pumping plant machine 14 two or more in pumping plant unit 13 runs simultaneously, the cooling water flow needed will increase, now, just need the water control valve 16 opening secondary water pump 52 water inlet end and water side, hydraulic pressure in water pipe 1 is detected and by holding wire 11 to switch board 6 feedback pressure signal by pressure sensor 10, switch board 6 exports frequency variation signal to auxiliary-motor 42, the rotating speed of auxiliary-motor 42 is controlled according to required hydraulic pressure size, ensure that to coordinate the running of feed pump 51 in outlet pipe 1, hydraulic pressure meets setting requirement.Feed pump 51 can be added to or/and the water inlet end of secondary water pump 52 from the hydraulic pressure of the return pipe 2 of pumping plant machine 14 outflow, play energy-conservation effect.Continue to be transported to cooling system 12 from return pipe 2 cooling water flowed in outlet pipe 1, move in circles periodical feeding successively that realize pumping plant unit 13.Steady-flow tank 3 is whole closing appliance when above-mentioned periodical feeding device normally runs, and as run into the situation that in return pipe 2, discharge is excessive or too small, can be controlled the water yield size in return pipe 2 by steady-flow tank 3.
