Description of drawings
Fig. 1 is the utility model horizontal layout schematic diagram;
Fig. 2 is that the utility model electric cabinet is arranged schematic diagram.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Cooling tower control system as shown in Figure 1 is equipped with motor 2 at cooling tower 1 internal upper part of routine, impeller 3 is installed on the motor, and the below is a water pond.The cooling tower below is equipped with secondary Thermal zinc plating bath steel base 4.Control valve 5 is established at the two ends, the every road of feed pipe pipeline of two tunnel parallel connections respectively, between filter 10, water circulating pump 12, Pressure gauge 8, temperature sensor 7, check valve 6 are installed successively; The water circulating pump two ends connect 9 and are connected with feed pipe by soft.Filter is installed so that regularly remove the impurity of deposition.Temperature sensor and heater are installed on the water pond of cooling tower.Electric control system is established electric cabinet 11, in establish controller, Pressure gauge, temperature sensor and heater are electrically connected controller.Control valve adopts copper valve, and Pressure gauge, temperature sensor shell, electric cabinet casing 25 adopt stainless steel to make, can be effectively anticorrosion for a long time.Feed pipe adopts two road parallel forms, but the using and the reserved realize the operation switching, prolong service life of equipment.Feed pipe, return pipe coat the aluminium sheet protective layer, and be both attractive in appearance, can play antisepsis again.
As shown in Figure 2, electric cabinet casing 25 adopts stainless steel to make, and electric cabinet divides three layers of layout from top to bottom, and the upper strata is arranged in order air switch 13, phase sequence 14, water level switch 15,1# relaying 16,2# relaying 17, water pump controller 18, temperature controller 19; The middle level is arranged in order 1# water pump contactor and electrothermal relay 20,2# water pump contactor and electrothermal relay 21, heater contactor and electrothermal relay 22, blower fan contactor and electrothermal relay 23; Lower floor is a connecting terminal block 24.Controller is a single-chip microcomputer micro computer automatic controller, comprises operation switch controller, fault alarm controller, overload protective controller, blower fan of cooling tower controller, deicing controllor.Wherein move switch controller inside and be provided with logic element.Controller can also connect remote controllers, realizes the operation Long-distance Control.
Single-chip microcomputer micro computer automatic controller integrated level high reliability is good, thereby reduces the inner complicated secondary connection of switch board in a large number, and superior cost performance greatly reduces controls cost, and has improved the reliability of device.Operation switch controller inside is provided with logic element, supposes to operate to first the 1# pump, when moving for the second time, can automatically switch to the 2# pump operation.Two water pump the using and the reserved, two water pumps take turns switchover operation when normally moving, and the running time of balanced two water pumps, have prolonged the maintenance and the maintenance cycle of water pump, thereby have increased the service life of whole system.
Native system adopts world-class motor, and is stable, noise is little, be more suitable for using near the residential block.Operation can substitute switching automatically, have fault simultaneously promptly switches and buzzer warning.Have phase shortage, anti-phase, under-voltage, overload protection.For example when detecting 1# pump operation fault (can be pressure detecting or current detecting), the 1# pump control circuit disconnects, closed 2# pump operation circuit of while, 2# pump operation; In like manner, 2# run time fault output 1# pump operation.Another water pump moves automatically when a water pump fault, and sends corresponding alarm signal, and whole system still keeps normal running status, does not influence user's normal use.For protecting water pump and system normally to move, the low-water level switch signal stops water pump and electrically heated operation when system's lack of water, has avoided the loss that causes because of lack of water.Controller of fan is controlled the blower fan start-stop automatically according to water temperature, on cooling water backwater (near the water tower place) pipeline, temperature sensor is set, and design temperature parameter (setting value and return difference), when temperature is lower than setting value down in limited time, output signal to the blower fan of cooling tower contactor, blower fan of cooling tower is shut down; In like manner can get, when return water temperature reaches capping, output signal to the blower fan of cooling tower contactor, the blower fan of cooling tower operation.The be cooled control of equipment return water temperature of the start and stop of blower fan of cooling tower, when less or winter environment temperature is low in cooling load, return water temperature stops fan operation in the time of also can correspondingly being reduced to a certain design temperature, rely on recirculated water to cool off naturally, when rising to setting value, opens return water temperature fan operation again, system can reduce the energy consumption that causes because of fan operation in a large number like this, brings tangible energy-saving benefit.Deicing controllor effectively prevents to freeze in the severe winter pipeline.Temperature sensor and heater are set on the cooling tower water pond, and design temperature parameter (setting value and return difference), when temperature is lower than setting value down in limited time, output signal to the heater contactor, the heater operation; When water temperature is heated to when reaching capping, output signal to the heater contactor, electrical heating stops.In the winter of northern severe cold, for preventing the system pipeline bursting by freezing, device is opened water pump operation when detecting the pipeline temperature and be lower than a certain design temperature, when still continuing to be reduced to a certain setting value as water temperature, heating prevents that current from freezing to recirculated water to open the pipeline electrical heating, when water temperature goes back up to a certain setting value, stop the pipeline electrical heating, continue to go up then to stop water pump operation (water pump did not stop when system was in normal operating condition).The anti-frost protection function has been avoided loss unexpectedly in user's use.Remote controllers can remote-controlled operation, realizes remote control by simple line, makes things convenient for the user in the far distance controlled of indoor realization to device.
This device can be avoided environment, site factors restriction by the factory system assembly, saves cost; Adopt copper valve, stainless steel casing Pressure gauge, temperature sensor and electric cabinet casing can guarantee the outdoor section non-corrosive, not corrode.
