Description
Technical field
This utility model belongs to underground coal mine assistant conveyance railless free-wheeled vehicle industry, more particularly, to a kind of machinery and fortune
General machine in transferring technology field and the double fan cooling system of electromotor.
Background technology
Railless free-wheeled vehicle is used for underground coal mine assistant conveyance, and its core is anti-explosion diesel engine.The heat of diesel engine is except base
The friction of this movement parts rises that heat is outer, and topmost is the high-temperature gas producing after mixture combustion in cylinder, and these will
Have a strong impact on use and the performance of diesel engine.And the function of diesel engine cooling system is it is simply that electromotor and drive aid
The heat that heated part is conducted out, is dispersed into around in bad border in time, make electromotor and actuating device can obtain reliable,
Effectively working environment.Most diesel engines adopt forced circulation water-cooling system at present.
Cooling system includes fan, heat radiator assembly, cooling water pipeline, expansion tank etc..Due to engine at extreme rear, I am public
Department uses bleed type fan, drives V belt to be driven by the belt pulley of outfan before bent axle.Expansion tank is used for giving
Radiator and diesel engine moisturizing.Heat radiator assembly includes water radiator, air-air intercooler and oil radiator, and three kinds of radiators are closed
Become together, compact conformation, save space.The effect of expansion tank is that cooling system is become permanent closure system, decreases
The loss of coolant, it is to avoid air enters, keeps the intrinsic pressure power of system stable.
There is water jacket in engine cylinder cap and cylinder block.Water pump will suck pressurization outside cooling water slave, makes cold water in water
In set, flowing, takes away the heat of adjacent components.After cooling water heat absorption, own temperature raises, and enters the heat radiator assembly at Herba Plantaginis end
Interior.Due to the blowing force of fan, the air in enging cabin is passed through radiator, take away in radiator the heat of cooling water and send into
Air.After the cooling water in radiator obtains cooling, in the presence of water pump, it is again introduced into water jacket.So circulate endlessly
Cool the high-temperature component of electromotor.
Due to the special working environment of underground coal mine, it is existing that " boiling " often when using in anti-explosion diesel engine cooling system
Destroy normal clearance as, movement parts expanded by heating in diesel-engine body, mechanical strength reduces, cause diesel engine that burning occurs
The phenomenons such as abnormal, power drop, oil consumption increase and insufficient lubrication, ultimately result in electromotor badly damaged.
Analysis occur this phenomenon the reason, mainly have following some：
1. underground coal mine haulage drift closing, ventilation is not enough, causes ambient temperature to raise.Diesel engine is for a long time this
Run under environment, cooling water can not effectively be cooled down.
2. enging cabin relative closure, diesel engine body and its gas extraction system are all heat generating components, cause in enging cabin
Air themperature is very high, and this hot blast is blowed to radiator by bleed type fan, and radiator cooling system reduces.
3. anti-explosion diesel engine is low-speed diesel engine, and rotation speed of the fan is determined by speed of crankshaft, and rotating speed is relatively low, empty
The mean wind speed that gas passes through radiator is relatively low, and the heat taken away is few.
4. fan and electromotor are driven by V belt by crankshaft pulley simultaneously, electromotor for packaged type, to adjust
The rate of tension of section belt.After electromotor long time running, belt loosens, and belt opposing pulleys will be caused to skid, make under rotation speed of the fan
Fall, pectinid amount reduces, impact radiating.
For the version of engine at extreme rear, bleed type fan can the motion of effectively utilizes vehicle when the relative wind that produces
Speed, but because railless free-wheeled vehicle travel speed is relatively low, relative wind velocity is inconspicuous to the radiating effect of vehicle.Meanwhile, bleed type wind
The high temperature air of enging cabin is introduced radiator although cooling the ambient temperature of diesel engine by fan, but and cooling not yet in effect is scattered
Cooling water in hot device, leads to diesel-engine body temperature to raise.In addition, bleed type fan is difficult to make the sky by radiator core body
Gas obtains good distribution so that the cooling water in radiator is not adequately cooled, and local temperature is high, and heat-sinking capability is relatively low.
