Described steady-flow tank communicates with backwater mother's pipe, and described steady-flow tank is provided with two position sensor, electronic moisturizing electrodynamic valve and manual water compensating valve, and when two position sensor detects steady-flow tank water level lower than home, electronic moisturizing electrodynamic valve works.
Being arranged with main pipeline and secondary duct between described water main pipe and backwater mother's pipe in parallel, described switch board automatically switched according to the operation time of centrifugal multistage pump multiple centrifugal pump, motor, completed the alternate run of main pipeline and secondary duct.
Described backwater mother's pipe entrance point is provided with y-type filter.
Described switch board controls converter output signal according to the feedback signal of electromagnetic flowmeter and pressure transducer, is automatically adjusted the rotating speed of centrifugal multistage pump multiple centrifugal pump, reaches to meet pumping plant unit watering equipment water inlet pressure requirements.
The temperature that described switch board detects according to return water temperature sensor, the design temperature of automatic comparison pumping plant unit watering equipment, to realize automatically loading and unloading of bearing shell cooling unit.
Electric machine speed regulation is run by the pressure that described switch board detects according to discharge pressure sensor, to meet the water inlet pressure requirements of pumping plant unit watering equipment.
The bearing shell of whole cooling system is cooled down unit, periodical feeding device and pumping plant unit watering equipment one cool cycles water system of composition by the present invention, cold source device, heat-exchanger rig, water supply installation are organically combined and optimize, forms a set of product reliable, energy-conservation, easy to maintenance.This device greatly reduces set-up time and the floor space of field apparatus, improves equipment reliability of operation and work efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described；
Periodical feeding device, bearing shell cooling unit 1 are connected by connecting gate valve 23 with pumping plant unit watering equipment 2, the PLC of switch board 15 is automatically adjusted the aperture of backwater electrodynamic valve 18 according to the temperature set, pressure, flow, control converter output signal according to the feedback signal of electromagnetic flowmeter 17 and back pressure sensor 10 simultaneously, it is automatically adjusted centrifugal multistage pump multiple centrifugal pump 3 rotating speed, reaches to meet pumping plant unit watering equipment 2 water inlet pressure requirements.The temperature that PLC detects according to water return pipeline temperature sensor 11, the design temperature of automatic comparison pumping plant unit watering equipment 2, instruction bearing shell cooler group 1 works as requested, bearing shell cooling unit 1 is upon receipt of the instructions, automatically load and unloading, meet the chilling temperature requirement of pumping plant unit watering equipment 2.
In system is run, there will be quantity of circulating water not foot phenomenon, for ensureing water supply balance amount of makeup water, add rustless steel steady-flow tank 6 in systems.Steady-flow tank 6 is mounted with two position sensor 8, electronic moisturizing electrodynamic valve 7 and manual water compensating valve 22, when level sensor detects steady-flow tank water level lower than home, PLC instruction moisturizing electrodynamic valve work make-up water source, it is automatically switched off electrodynamic valve, thus ensureing that system has the water yield of abundance when replenishing water to.For convenience of the on-the-spot interim make-up water source of equipment debugging, system increases manual water compensating valve 22.
For preventing water supply line from having welding slag to retain when erecting and welding, cause pumping plant unit watering equipment 2 cooler to block, y-type filter 9 is set at backwater mother's pipe 19 entrance point.
Installing PLC and converter on switch board 15, PLC detects when system has fault or be abnormal, sends alarm signal, and operator carry out failture evacuation according to display screen prompting, improve the reliability of pumping station operation.
