A kind of diesel generating set radiation fan arrangements for speed regulation of the present utility model also comprise single-chip microcomputer 8 and signal picker 11, single-chip microcomputer 8 is connected by integrating control cable 10 with signal picker 11, single-chip microcomputer 8 is provided with a pwm signal driver 81, and pwm signal driver 81 is connected by integrating control cable 10 with the electromagnetic coil 36 on silicon oil filled fan clutch 3.The single-chip microcomputer 8 adopted in the utility model is AT89C51 type single-chip microcomputer, this single-chip microcomputer 8 is a kind of single-chip microcomputers being integrated with pwm signal driver 81, modulated by the pulsewidth of the pulse-width signal exported pwm signal driver 81, actuate valve stem 351, valve block 35 is driven by valve rod 351, realize the control to the oil outlet 321 opening and closing time, final realization is to the cooling water tank end driven member 31 of silicon oil filled fan clutch 3 and diesel engine end driven member 32, and the adjustment of relative rotation speed between driving disc 33, and the adjustment of radiation fan 5 rotating speed.
During diesel generating set start, when diesel engine 9 temperature is lower, single-chip microcomputer 8 controls electromagnetic coil 36 by pwm signal driver 81 and disconnects, and controls valve block 35 and is in closed condition, namely valve block 35 closes oil outlet 321, and the silicone oil in shoe cream room 303 cannot enter active chamber 302.Driving disc 33 effectively cannot be engaged by silicone oil with cooling water tank end driven member 31 and diesel engine end driven member 32, and now silicon oil filled fan clutch 3 is in separated state.After diesel engine 9 runs heating, single-chip microcomputer 8, by pwm signal driver 81, controls electromagnetic coil 36 adhesive, and control valve block 35 and open oil outlet 321, the silicone oil in shoe cream room 303 enters active chamber 302 and maze trough 301.Because silicone oil has very large viscosity, therefore driving disc 33 engages with cooling water tank end driven member 31 and diesel engine end driven member 32 by silicone oil, drive radiation fan 5 High Rotation Speed, the temperature of cooling water tank 4 is higher, the time that valve block 35 is opened is longer, the time of closing is shorter, the silicone oil entering active chamber 302 and maze trough 301 is more, the rotating speed of cooling water tank end driven member 31 and the relative driving disc 33 of diesel engine end driven member 32 is faster, radiation fan 5 rotating speed is faster, thus effective cooling diesel generating set, and the temperature of cooling liquid in cooling water tank 4 is effectively reduced.Signal picker 11 is by the sensor in radiation fan 5 and cooling water tank 4, gather coolant temperature in radiation fan 5 rotating speed and cooling water tank 4, continue to transmit coolant temperature and radiation fan 5 rotary speed information to single-chip microcomputer 8, single-chip microcomputer 8 controls the switch of valve block 35 by pwm signal driver 81, fine adjustment enters the amount of the silicone oil of active chamber 302, reaches the object to radiation fan 5 intelligent speed-regulating.Silicon oil filled fan clutch 3 is exactly the associated change realizing radiation fan 5 rotating speed and diesel engine 9 like this.
A kind of diesel generating set radiation fan arrangements for speed regulation of the present utility model, by single-chip microcomputer 8 and silicon oil filled fan clutch 3, control the rotating speed of radiation fan 5.Signal picker 11 is also the electronic Control for Diesel Engine device of diesel generating set simultaneously, while the every technical parameter gathering diesel engine 9 operation, to oil spout and the rotational speed regulation of diesel engine 9.Silicon oil filled fan clutch 3, by the pwm signal driver 81 on single-chip microcomputer 8 and single-chip microcomputer 8, drives electromagnetic coil 36 and valve block 35, controls the closure or openness of oil outlet 321, regulates the amount entering the silicone oil of active chamber 302 and maze trough 301.Single-chip microcomputer 8 is by the communication with signal picker 11, read freezing mixture in cooling water tank 4 temperature and and the data such as radiation fan 5 rotating speed, and convert thereof into as corresponding PWM (pulsewidth modulation) signal, exported by pwm signal driver 81, control the adhesive of the electromagnetic coil 36 of silicon oil filled fan clutch 3, thus regulate opening time and the shut-in time of valve block 35, control the amount that silicone oil enters active chamber 302, step-less adjustment is carried out to the cooling water tank end driven member 31 of silicon oil filled fan clutch 3 and the rotating speed of diesel engine end driven member 32, final realization is to the step-less adjustment of radiation fan 5 rotating speed and the control to diesel generating set heating, thus reach automatic control and energy-conservation object.Wherein, in cooling water tank 4, coolant temperature is higher, and the opening time of valve block 35 is longer.Shut-in time is shorter, and the silicone oil entering active chamber 302 and maze trough 301 is more, and radiation fan 5 rotating speed is faster.
In addition; Drive Protecting Circuit 82 is also provided with in single-chip microcomputer 8; once whole system circuit breaks down; system can cut off contacting between silicon oil filled fan clutch 3 and signal picker 11 automatically; thus the oil outlet 321 of silicon oil filled fan clutch 3 is often opened; radiation fan 5, with fixed rotating speed full-speed operation, ensures the normal work of unit.
The technique effect of diesel generating set radiation fan arrangements for speed regulation is shown in accompanying drawing 4 and table 1.
Certain model diesel generating set, rated output power 2000kW, fan attachment rotating speed 1500rpm, radiation fan 5 consumes diesel engine power 75kW.Have employed two groups of a kind of diesel generating set radiation fan arrangements for speed regulation of the present utility model, two groups of radiation fans 5 of configuration and the total power consumption of silicon oil filled fan clutch 3 power consumption are 68kW, often organize 34kW, when full speed running than originally more energy-conservation 10%.When being in the diesel generating set initial start of cold state, silicon oil filled fan clutch 3 is in separated state, and the rotating speed of radiation fan 5 only has 350rpm, the total power consumption of two radiation fans 5 only has 4kW, energy-saving effect clearly, also makes the quick heat engine of diesel engine simultaneously, reduces mechanical wear.The temperature of machine room can be kept under the environment in north winter.When diesel generating set 4 operates in non-full load condition, the temperature of diesel engine 9 also can decline, and at this moment radiation fan 5 synchronization declines, and radiation fan 5 consumed power declines.When diesel generating set operates in 75% load, radiation fan 5 rotating speed drops to 1270rpm, the consumed power 26kW of every platform radiation fan 5; When diesel generating set operates in 50% load, radiation fan 5 rotating speed drops to 910rpm, and the consumed power of every platform radiation fan 5 is 13.3kW.Along with the decline of radiation fan 5 rotating speed, the noise also corresponding decline that diesel generating set runs, the noise decline 3-5dB outside a meter.
Table 1 diesel generating set cooling water tank temperature, radiation fan and silicon oil filled fan clutch power consumption, with radiating fan rotation speed plotted curve
Diesel generating set radiation fan arrangements for speed regulation can reduce the working life of oil consumption, emissions reduction, prolongation diesel generating set, have good economic benefit and social benefit.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the utility model is described, and be not used as restriction of the present utility model, as long as in spirit of the present utility model, all will drop in Claims scope of the present utility model the change of the above embodiment, modification.
