Definitions

  • the present invention relates to a method for fuel preheating and the preheating system thereof, more specifically, to a method for heating cooling liquid to start preheating and the heating system thereof.
  • the excavator fuel needs to be preheated for solving the issue that when the excavator started the diesel fuel (fuel) can't beat the fire, especially in the North China, it is the normal phenomenon.
  • the resistance wire heating inlet form is employed by the common excavator fuel preheating systems via the hot air to heat the diesel fuel and the fuel, so as to ensure the normal initiate of the excavator.
  • the temperature even reaches to the minus 30 ° C, heating the inlet air can't guarantee the normal initiate of the excavator, which makes excavator can't work properly, bring great puzzle to customers and service engineers.
  • the preheating method and the heating system are particular important for which can decrease the fault rate, heat effective, protect the environment.
  • the present invention aims to solve the above mentioned problems, a new heating system is designed by the heating system so as to heat the cooling liquid and to remove the phenomenon of the diesel fuel frozen with the wax, and to use the exhaust hot flow of the heating system to achieve the function of heating fuel.
  • This invention has disclosed a method for heating cooling liquid to start preheating, wherein it comprises:
  • Step 2 further comprises:
  • step 4 further comprises:
  • step 5 further comprises:
  • a system of heating cooling liquid to start preheating wherein it comprises:
  • a pump is provided to the fuel inlet for absorbing the fuel from the fuel tank
  • a nozzle is provided to the fuel outlet for mixing high pressure fuel mist with air.
  • the exhaust pipe end is connected to comprises guiding cover with upright opening of which opening area is greater than the engine base, the exhaust pipe is provided with an air door for discharging the smog from the initial heating.
  • the heater air-inlet device comprises a motor which drives an fan located in the in heater for absorbing the outside air into the heater.
  • the heater covered with the circulating water pipe is provided with a heat exchanger interlayer, which is on the circulating water pipe, heat conductive slices is provided inside the interlayer, the heat conductive slices are evenly attached to the surface of the circulating water pipe.
  • the present invention heats diesel fuel and fuel by the heater, the principle of the heater is the fuel pump driven by the motor, the inlet fuel is sent from the fuel pipe to the nozzle, the inlet fuel is ejected by the nozzle depends on the pressure function, the ejected high pressure fuel mist mixes with the air absorbed by the air fan in the combustor and ignited by the ignition electrode, in the combustor after sufficient combustion, fuel gas flows through heat conductive slices of the heat exchanger interlayer, by heating heat conductive slices to convey most of the heat to the cooling fluid in the heat exchanger interlayer the heating system is used to heat the cooling fluid at first, and using the pump to make the heated cooling fluid circulate in the internal of the engine, so as to achieve the heat of the engine fuel; Secondly, using the hot air generated by heater fuel combustion, guiding it to the bottom of the engine by the exhaust pipes, so as to achieve the function of heating the fuel.
  • the present invention discloses a system of heating cooling liquid to start preheating and the schematic diagram of the process of heating cooling liquid to start preheating to illustrate the method of heating cooling liquid to start preheating.
  • S 1 represents the abbreviation of the step 1, which is used to express step 1, other steps are expressed in S similarly
  • the present invention comprises the following steps:
  • igniting the fuel in Step 2 further comprises the following several specific implementation processes:
  • Step 5 further comprises:
  • the schematic diagram of the system of heating cooling liquid to start preheating comprises:
  • a pump 7 is provided to the fuel 6 inlet for absorbing the fuel from the fuel tank 8
  • a nozzle 31 is provided to the fuel 6outlet for mixing high pressure fuel mist with air.
  • the exhaust pipe 5 end is connected to comprises a guiding cover 2 with upright opening of which opening area is greater than the engine 1 base, thus exhaust can cover the bottom of the engine 1 well, it benefits to heat the engine 1 rapidly and decreases the unwanted consumption of the heat; the exhaust pipe 5 is provided with an air door 4 for discharging the smog from the initial heating; a valve is provided to the air door 4 used to achieve the conversion of the exhaust.
  • heater 10 ir-inlet device comprises a motor 9 which drives an fan 21 located in the in heater 10 for absorbing the outside air into the heater 10.
  • the heater 10 covered with the circulating water pipe 12 is provided with a heat exchanger interlayer, which is on the circulating water pipe 12, heat conductive slices is provided inside the interlayer, the heat conductive slices are attached to the surface of the circulating water pipe 12 uniformly, this can increase the heating efficiency maximized, making the present invention has broad prospects. While the present disclosure has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims, and equivalents thereof.
