Water of the present utility model is isolated electric heating fuel-firing preheating device, also comprise temperature control system, it comprises diode, slide rheostat, temperature transducer, the switch that connects successively, and controllable silicon, diode also connects positive source, switch also connects power cathode, and silicon controlled negative electrode, the control utmost point, anode connect the current input terminal of heating core, temperature transducer, the current output terminal of temperature transducer respectively, and heating core also connects positive source; Temperature transducer is positioned at the housing inner chamber.
In Fig. 1, heat collection gate 2 and heating core 3 are installed in the housing 1, and heating core 3 helicals are around in around the heat collection gate 2 and maintain certain distance, between be full of WATER AS FLOW MEDIUM.Cap 8 is loaded on housing 1 upper surface, plays the purpose of dustproof leakproof.Sealing and dustproof cap 6 is installed on the water filling hole place of cap 8, plays the dust-tight effect.The oil inlet and outlet of heat collection gate 2 passes cap 8 and is located by set screw nut 5 and is installed on the cap.Employing is installed rubber seal 4 additional and is played seal action between heat collection gate 2 and cap 8 lower surfaces.The terminal of heat collection gate 2 and temperature transducer 7 pass cap 8 and are fixedly mounted on the cap 8, adopt bonding method.Drain screw 9 is installed on the lower surface of housing 1, between adopt and be threaded, scribble the effect that a certain amount of sealer plays leakproof during installation between the two.Four openings of the rear surface of housing 1 are used for and the external structure location and installation.In Figure 18, fuel oil flows out this device from a filler opening inflow of heat collection gate 2 from another oil outlet, while Yi Bian the heat that utilizes heating core 3 to produce carries out flowing into the partial continuous heating of heating outflow to the instantaneous fluid that are in the heat collection gate 2.And control the temperature of the fluid that flows out this device by the temperature of temperature control system control media water.
The connection principle of temperature control circuit is: heating core 3 one of them terminal and positive source and 13 anodal linking to each other of diode, the other end links to each other with the negative electrode of controllable silicon 12, the negative pole of diode 13 links to each other with slide rheostat 14, the control utmost point of controllable silicon 12 links to each other with the other end of temperature transducer 7 with the other end of slide rheostat 14, the other end of the anode of controllable silicon 12 and temperature transducer 7 links to each other with switch 10, another termination power cathode of switch 10 is seen Fig. 2.The wiring terminal of heating core and temperature transducer passes cap and the external temperature control circuit links, and constitutes temperature control system.Temperature control system by temperature control circuit, temperature transducer, encapsulation box, wiring is emitted and lead is formed.Wiring is emitted with the wiring terminal of temperature transducer and heating core and is linked to each other, and in the encapsulation box temperature control circuit is housed.
The working principle of whole device is: behind switch 10 closed connection temperature control circuits, because the temperature of the oil in water in the housing 1 and the heat collection gate 2 is low, the resistance of temperature transducer 7 is bigger, controllable silicon 12 obtains the high level conducting, heating core 3 begins the heating of the water in the housing 1, and the fluid that the temperature of water is passed in the heat collection gate 2 raises oil liquid temperature.When the temperature of water reached certain value, the resistance of temperature transducer 7 reduced, and the control utmost point level of controllable silicon 12 reduces, and controllable silicon 12 stop conductings, heating core 3 stop heating.When fuel oil temperature drops to setting value when following once more, heating core 3 is once more to the water heating, thereby controls fuel oil dynamically in uniform temperature.Can regulate the voltage distribution that slide rheostat 14 changes slide rheostat and temperature transducer 7 according to actual conditions, thereby control the temperature of the water when making heating core 3 conductings, reach the purpose that changes the oil liquid temperature value that flows out this device.
Water of the present utility model is isolated electric heating fuel-firing preheating device, makes fuel oil improve uniform temperature in advance before fuel oil enters Injection Pump or motor, to improve owing to the low excessively fuel performance parameter that causes of fuel oil temperature descends to the influence of engine operation.Especially can be before engine start will enter fuel Heating before the motor to uniform temperature, thereby improve motor startability at low temperatures by this device.
Water of the present utility model is isolated electric heating fuel-firing preheating device, and whole the employing is encapsulated in one independently in the rectangular case with heating part, is installed on before motor after the oil transfer pump or the Injection Pump position near motor.Near with the motor distance, reduced along the journey temperature loss.Instantaneously when fuel oil installs by this heated, and be controlled at a definite value by the temperature that temperature control system will flow out the fluid of this device by continuity.Employing with heating part be encapsulated in one independently the structure in the rectangular case need not that oil supply system is carried out big transformation and just can reach the deficiency of improving aspect heating time, capacity usage ratio and the Economy three of common heating method when the original state, reduced and manufacture and design or reequip cost.By WATER AS FLOW MEDIUM fuel oil is carried out the uninterrupted continuity heating of part, just carry out simultaneously, reduced scattering and disappearing of temperature while importing to heat to export on one side, few in the amount of fuel of original state and arbitrary instantaneous participation heating, improve rate of heating, shortened heating time.Can also further shorten initial heating time by the method that in housing, adds hot-water flooding.Thereby reached the purpose that shortens initial heating time, improves capacity usage ratio and Economy three aspects.
Cap is fixed in the housing upper surface under four screw effects, play effect dustproof, the sealing anti-overflow.Design has four openings that externally install and fix on the ear end face of housing, is used for the location and installation with external structure.Heating core is surrounded on around the heat collection gate and maintains certain distance, is filled with aqueous medium between the two, the Security when guaranteeing fuel Heating.The design of cap upper surface has water filling hole, and the water filling hole place is equipped with dust cover.The housing bottom design has the dewatering outlet.The oil inlet and outlet of heat collection gate passes cap and links to each other with outside oil supply system, fixedlys connected by nut with cap, and fuel oil enters thus and flows out this device.The diameter of oil inlet and outlet is 1/2nd of the total cross-sectional flow area of inner heat collection gate, guarantee that fuel oil has the enough time to absorb the temperature and basic the maintenance and the synthermal value of water of water by heat collection gate the time, can control temperature by the temperature of temperature control system control media water by the fluid of heat collection gate.The heat that heating core produces is transmitted to heat collection gate by WATER AS FLOW MEDIUM, and the fuel oil of the heat collection gate of being flowed through then absorbs, and reaches the purpose of heated fuel oil.The fuel Heating process is to heat the part fuel oil continuity heating of flowing out on one side while flowing into.And the indirect control flows of temperature by control water through the temperature of the fuel oil of heat collection gate a definite value, improve because the low excessively fuel performance parameter that causes of oil liquid temperature descends to the influence of engine operation.Especially can be before engine start the fuel oil that is about to enter before the motor be heated rapidly to uniform temperature, improves motor startability at low temperatures by this device.
