As a further improvement of the present invention, the water tank blower is controlled by generator set controller, and generator set controller acquires water The temperature sensor signal of temperature sensor is converted into temperature value, is then issued and is run come feed-tank blower according to temperature value Halt instruction.
As a further improvement of the present invention, the general opening temperature of engine thermostat is at 80 DEG C or so, this temperature Angle value is determined according to the model of engine.
As a further improvement of the present invention, the generator set controller has the function of detecting three-phase voltage, and has water The high warning function of temperature, and can show real-time temperature values, and protection act can be carried out in water temperature over-high.And can to alarming value and Action value is configured, and meets different type needs.
As a further improvement of the present invention, it is configured with thermal overload relay on the contactor, is run in generator different Often and in the case where overcurrent protected.
As a further improvement of the present invention, the water temperature sensor is mounted on engine thermostat front end, to engine Cylinder body temperature measures, and is transferred to generator set controller with resistance value signal.
Compared with prior art, the device have the advantages that are as follows: invention be provided with water temperature sensor, unit allocation Device, thermostat, A.C. contactor realize the intelligentized control method of blower, and degree of intelligence is high, intelligent control system proposed by the present invention System, ensure that the normal table operation and its service life of water tank blower, and can save the utilization of the energy, substantially increase power generation The stability and its economic benefit of unit.

Specific embodiment
It is right in the following with reference to the drawings and specific embodiments in order to which technical solution of the present invention and beneficial effect are more clearly understood The present invention is described in further detail, it should be understood that and the specific embodiments described herein are only used for understanding the present invention, Be not intended to limit the present invention, it is obtained by those of ordinary skill in the art without making creative efforts it is all its His embodiment, shall fall within the protection scope of the present invention.
Referring to Fig.1, Fig. 2 provides a kind of a kind of implementation of generating set cistern fan intelligent control system of the present invention Mode, including engine 2, generator 8, independent fan type water tank 7, water temperature sensor 3, water tank blower 6, engine thermostat 4, Generator set controller 1 and cooling line 5, the water temperature sensor 3 are arranged in 4 front end of engine thermostat, the water temperature sensor 3 It is connect with generator set controller 1, temperature signal is reached into generator set controller 1, described independent 7 one end of fan type water tank passes through water lines It is connect with the coolant line 5 of unit, the coolant line 5 is connect with engine thermostat 4, and the other end and engine 1 connect It connects, water tank blower 6 is equipped on the independent fan type water tank 7, the water tank blower 6 is controlled by generator 8, passes through unit control Device 1 processed is acted according to water temperature in body come control contactor, to drive the operation of water tank blower 6 and stop.
The water tank blower 6 is controlled by generator set controller 1, and generator set controller 1 acquires the temperature sensor of water temperature sensor 3 Signal is converted into temperature value, then issues operation halt instruction according to temperature value come feed-tank blower 6.
The general opening temperature of the engine thermostat 4 at 80 DEG C or so, this temperature value according to the model of engine 2 come It determines.
The generator set controller 1 has the function of detecting three-phase voltage, and has the high warning function of water temperature, and can show real When temperature value, and protection act can be carried out in water temperature over-high.And alarming value and action value can be configured, meet different Type need.
It is configured with thermal overload relay on the contactor, is protected in the case where generator operation exception and overcurrent Shield.
The water temperature sensor 3 is mounted on 4 front end of engine thermostat, measures to temperature in engine cylinder body, with Resistance value signal is transferred to generator set controller.
When using this device specifically, most start first to adjust the parameter inside generator set controller 1, be set as output at 80 DEG C 6 enabling signal of water tank blower starts engine 2 then by generator set controller 1, rises to it after idle running 30s specified It is run under state, in the process, because engine 2 is in the state of idle running, water temperature increases more slow, unit control at this time The temperature that device 1 processed detects does not arrive its internal temperature value also, and the starting that water tank blower 6 does not receive generator set controller 1 at this time refers to It enables, 6 not running of water tank blower.
After completing above-mentioned steps, to engine, gradually loading observes water temperature sensing to 80% rated power operation at this time Device 3, in quick increase, when water temperature rises to 80 DEG C, engine thermostat 4 is opened, and engine-cooling system enters big Circulation pattern, while generator set controller 1 issues start command to water tank blower 6, water tank blower 6 is started to work.Start laying down When machine loads, water temperature sensor 3 is observed, with the reduction of engine loading, temperature can also be gradually reduced, and temperature is lower than and sets at this time Definite value, generator set controller 1 issue instruction to water tank blower 6 after 5min is delayed, and water tank blower 6 can be out of service, to reach Energy-efficient effect.
When unit breaks down and shuts down, generator set controller 1 can issue signal to water tank blower 6, so that it is stopped working, keep away Exempt from due to compressor emergency shutdown, revolving speed, voltage reduces the damage caused to water tank blower 6.
