Abstract

The utility model relates to a heater for starting a water-cooled engine, belonging to the technical field of an F type mechanical engineering. The utility model solves the technical problem that the water-cooled engine is difficult to be started in the state of low temperature. The heater for starting a water-cooled engine is composed of an air supplying system, a water circulating system, a heat exchanger and a combustion system; is characterized in that the oil of the combustion system is supplied by an atmospheric pressure oil tank, and one section of an oil pipe is served as a preheating oil pipe in a combustion chamber, and one end of the air distribution chamber of the air supplying system is fixed with an oil baffle plate. The utility model is suitable for the water-cooled engine starting and heating under the state of low temperature.

Description

Heater for starting water cooled engine

The utility model is a water cooled engine starting heater, belongs to F class mechanical engineering technical field.

Water cooling in prior technology engine start, particularly water-cooled diesel engine are difficult at the low-temperature condition actuating ratio, make it starting at the bottom of often adding hot-water flooding and toast engine oil simultaneously to motor, and this method is time-consuming, effort, unhygienic; The employing cold conditions primed starting that has has aggravated engine scuffing, influences working life; What have rents or builds warm storehouse, so that starting, its shortcoming is the expense height, and the condition that adds is limit, and what have can't build warm storehouse.

The utility model purpose is a kind of heater of design, and the circulating water with the heating water cooled engine again by the hot water heated engine, makes motor evenly be heated to smooth starting by low temperature, overcomes the deficiencies in the prior art.

The technical solution of the utility model is: by motor (4), blower fan (3), airduct (2), the air feed system that gas distributing chamber (12) forms and by motor (4), water pump (5), water outlet (6), connecting tube (7), the water cycle system that water inlet (23) is formed reaches by firing chamber (22), be around in a plurality of water pipes (13) that firing chamber (22) is evenly arranged on every side, be fixed in the igniter plug (20) of nozzle frame (19), the heat exchanger (8) that relief opening (21) is formed and by oil injecting nozzle (19), modulating valve (18), oil pipe (9), the burning that switch (10) is formed is the water cooled engine starting heater that four parts are formed, oil pipe (9) connection that is that it is characterized in that burning has oil outlet (24), oil switch (25), barometer (26), the air pressure oil tank (10) of oiling valve nozzle (27), the gas distributing chamber (12) of air feed system is fixedly installed in the centre of heat exchanger (8) and one and rectifies oil injecting nozzle (19) direction is fixed with oil baffle (14), one section of the oil pipe (9) of burning system places and is preheating oil pipe (15) in the firing chamber (22), and this preheating oil pipe (15) is arranged between oil baffle (14) and the oil injecting nozzle (19).Oil baffle (14) makes the fuel oil that sprays produce the atomizing of splashing, and is convenient to abundant burning, and preheating oil pipe (15) makes fuel-firing preheating be beneficial to burning.

The support (1) that will be fixed in heater is installed in the appropriate location of close motor, water outlet (6) and water inlet (23) are communicated with the cooling water recirculation system of water cooled engine with pipe fitting, DC electrical source is connected with motor (4), igniter plug (20) respectively, after the oiling valve nozzle (27) of air pressure oil tank (10) locates to refuel (gasoline or diesel oil or the two miscella), seal lid and squeeze into air pressure from this place, barometer (26) shows the pressure size.Air pressure oil tank (10) is communicated in preheating oil pipe (15) with oil pipe (9).The structure of air pressure oil tank (10) multiple fuel oil easy to use.

During work, send electricity for igniter plug (20), open oil switch (25) and switch (10), after squeezing into air pressure, fuel oil is from oil injecting nozzle (19) ejection and lighted, and send electricity for motor (4), blower fan (3) and water pump (5) work, burning is normal, close the power supply of igniter plug (20), cold water is heated and circulates in motor, motor is progressively heated up be heated to smooth starting, close oil switch (25) and switch (10), again the DC power supply switch of disable motor (4).

Wind enters air feed system from blower fan (3), and combustion-supporting, waste gas is discharged from relief opening (21) to firing chamber (22).Enter heat exchanger (8) from the cold water of motor from water inlet (23) and be heated, hot water enters water pump (5) and pumps into motor through connecting tube (7).Fuel oil is pressed into oil injecting nozzle (19) and ejection is lighted by igniter plug (20) from air pressure oil tank (10) through air pressure, mixes with wind in firing chamber (22) and burns, to heat the water in a plurality of water pipes (13).

The utility model compared with prior art has advantages such as energy consumption is low, the thermal efficiency is high, starting is fast, available multiple fuel oil.

Description of drawings is as follows:

Fig. 1 is the monnolithic case figure of heater.

Fig. 2 is the cut-away view of heater.

Wherein: 1 is support, and 2 is airduct, and 3 is blower fan, 4 motors, 5 water pumps, 6 water outlets, 7 connecting tubes, 8 heat exchangers, 9 oil pipes, 10 ' switch, 10 air pressure oil tanks, 12 gas distributing chamber, 13 water pipes (a plurality of), 14 oil baffles, 15 preheating oil pipes, 18 modulating valve, 19 ' nozzle frame, 19 oil injecting nozzles, 20 igniter plugs, 21 relief openings, 22 firing chambers, 23 water inlets, 24 oil outlets, 25 oil switchs, 26 barometers, 27 oiling valve nozzles.

Fig. 1 and Fig. 2 are embodiment of the utility model, preheating oil pipe (15) can also be changed into the volute of lengthening or the swan-neck of lengthening, to improve the fuel-firing preheating effect; Also can change a plurality of water pipes into water jacket type, to realize a plurality of embodiments.
