Abstract

The invention discloses an engineering crane engine preheating system, relates to an engine of an engineering crane and solves the technical problem that the engine is difficult to realize cold start. The engineering crane engine preheating system comprises a circulating pipeline formed by an engine and a cab evaporator, wherein a heater is serially connected in the circulating pipeline, a water pump is connected in parallel in the circulating pipeline, a No.1 electromagnetic valve, a No.2 electromagnetic valve and a No.3 electromagnetic valve for controlling engine preheating and cab heating are arranged, the engine is provided with a temperature sensor, and the No.1 electromagnetic valve, the No.2 electromagnetic valve, the No.3 electromagnetic valve, the water pump, the heater, the evaporator and the temperature sensor are connected with a controller through circuits. The engineering crane engine preheating system has the advantages that the engine can be normally started under low-temperature environments at 30DEG C below zero and the working efficiency is improved; the cab can be heated when the engine is not started and the energy consumption is reduced.

Description

Crane preheating system for engine
Technical field
The present invention relates to the motor of crane, particularly the pre-heating system of engine cold-start.
Background technique
The power of crane provides primarily of motor, but at the northern area of China, winter temperature is very low, and the minimum temperature of the Northeast can reach minus 20 degrees, even lower.Under such weather conditions, engine oil viscosity is large, and resistance increases, and fuel oil can not fully be atomized, and causes engine cold-start difficulty.Cold start-up harm is serious, oil consumption consuming time, and tail gas pollution is serious, and cold start-up once, and the wear extent of parts is equivalent to normally travel 300km, loses surprising.So motor must possess the function of cold-starting, otherwise heavy losses can be caused.In the past, people had summed up the method for some engine cold-startings according to practical experience, and as filling with hot water, baking suction tude, flame preheat etc. directly to cylinder body, owing to affecting by actual conditions, and process is loaded down with trivial details, often can not realize, and there is potential safety hazard.
Summary of the invention
Object of the present invention is intended to the shortcoming overcoming prior art, provides a kind of crane preheating system for engine, solves the technical problem of engine cold-start difficulty.
The present invention is achieved through the following technical solutions:
A kind of crane preheating system for engine, comprise: the circulation loop be made up of motor and driver's cab vaporizer, it is characterized in that: heater in parallel in described circulation loop, to connect water pump, and be provided with No. I solenoid valve controlling engine warming up and driver's cab heating, No. II solenoid valve, No. III solenoid valve, described motor is provided with temperature transducer, and described No. I solenoid valve, No. II solenoid valve, No. III solenoid valve, water pump, heater, vaporizer and temperature transducer are connected with controller circuitry.
The present invention compared with prior art, has the following advantages and beneficial effect:
The present invention can make motor normally start under the low temperature environment of subzero 30 DEG C, substantially increases working efficiency, and the working life of motor extends.The present invention, can Short Time Heating driver's cab when motor does not start, and has saved energy consumption.In the present invention, heater is ripe product, and consume energy low, storage battery can ensure that motor normally starts.
Accompanying drawing explanation
Fig. 1 is the structural representation of present pre-ferred embodiments.
Embodiment
Embody the exemplary embodiments of feature & benefits of the present invention, will describe in detail in the following description by reference to the accompanying drawings.The present invention can have various changes in different embodiments, neither departs from protection scope of the present invention, explanation wherein and to be shown in be when the use that explain in essence, and is not used to limit the present invention.
As shown in Figure 1, a kind of crane preheating system for engine, comprise: the circulation loop be made up of motor 1 and driver's cab vaporizer 2, heater 3 in parallel in described circulation loop, to connect water pump 4, and be provided with No. I solenoid valve 5, No. II solenoid valve 6, No. III solenoid valve 7 controlling engine warming up and driver's cab heating, be provided with temperature transducer 11 in described motor 1, described No. I solenoid valve 5, No. II solenoid valve 6, No. III solenoid valve 7, water pump 4, vaporizer 2, heater 3 and temperature transducer 11 are connected with controller 8 circuit.
The present invention separately to motor 1 preheating, can heat driver's cab vaporizer 2 separately, also can when engine work to driver's cab heat supply.
The first situation, when the independent warm-up the engine 1 of needs, instruction is sent by the program of controller 8, open No. I solenoid valve 5 and No. III solenoid valve 7, start heater 3, the continuous circulating-heating of water in heater 3 pairs of motors 1, during by water temp. heating to setting value (as 40 DEG C), motor 1 just can normally start; When water temperature exceedes setting value (as > 40 DEG C), feed back to controller 8 by the temperature transducer 11 of motor, the program of controller 8 sends instruction, and close No. I solenoid valve 5 and No. III solenoid valve 7, heater 3 quits work.
The second situation, when not needing ato unit 1, and when needing driver's cab heat supply, instruction is sent by the program of controller 8, open No. II solenoid valve 6 and No. III solenoid valve 7, and open water pump 4, the continuous circulating-heating of water in heater 3 pairs of driver's cab vaporizers 2; If when not needing driver's cab heat supply, send instruction by the program of controller 8, close No. II solenoid valve 6 and No. III solenoid valve 7, and switch off the pump 4, heater 3 quits work.
The third situation, when also giving driver's cab heat supply while engine work, sends instruction by the program of controller 8, open No. I solenoid valve 5 and No. II solenoid valve 6, and open water pump 4, the hot water in motor 1 body, by driver's cab vaporizer 2, is supplied to driver's cab heat.
The effect of water pump in system: because the motor distance driver's cab of crane is distant, arrives vaporizer resistance from the water engine body large, by water pump, water is pumped to vaporizer, reach the object of preheating driver's cab.
The present invention specifically can implement in a variety of forms and not depart from the spirit of invention, so be to be understood that, above-described embodiment is not limited to aforesaid details, and should explain widely in claim limited range, therefore fall into the change in claim or its equivalent scope and remodeling, all should be claim and contained.
