Embodiment 1

[0034] Such as figure 1 , figure 2As shown, this embodiment provides a hydraulic air supply and fuel system for diesel burners, which is mainly used for air supply and fuel supply in diesel burners, and the ratio of air supply and fuel supply is controlled according to combustion needs . The system mainly includes two subsystems, namely the air supply system and the fuel system; among them, the function of the air supply system is to supply air to the burner, and the function of the fuel system is to inject diesel fuel, diesel fuel and gas into the burner. The mixed combustion generates heat, which is the work of the burner. The structure and working principle of the air supply system and the fuel system will be described in detail below, and on this basis, the use method of the system will be given.

[0035] Such as figure 1 As shown, the air supply system includes an air supply and oil supply part, a first proportional reversing valve 15 and a fan motor. Among them, th...

Embodiment 2

[0049] The hydraulic air supply and fuel system of the diesel burner in Example 1 is used to supply air to the burner through the start of the fan motor. However, during the operation of the fan motor, the oil inlet pressure may exceed its working pressure, so that the fan motor The motor is overloaded, which will affect its life and even cause danger; in addition, at the moment when the first proportional reversing valve 15 cuts off the oil flow, the fan motor is still rotating due to inertia, and the oil supply has been cut off at this time, which will cause Cause hydraulic shock, damage to fan motor, and air supply system. In both cases, there will be adverse effects and need to be effectively avoided. Therefore, this embodiment is optimized on the basis of embodiment 1, and a safety protection circuit and a brake oil supply circuit are added to the air supply system to avoid the occurrence of the above two situations.

[0050]Specifically, the brake oil supply circuit inc...

Abstract

The invention discloses a diesel burner hydraulic air supply and fuel system and a using method of the diesel burner hydraulic air supply and fuel system, and belongs to the technical field of burnerhydraulic control. The system comprises an air supply system and a fuel system, the air supply system comprises an air supply and oil feeding portion, a first proportional directional valve and a fanmotor, the fan motor is connected with the air supply and oil feeding portion through the first proportional directional valve, the fan motor is in transmission connection with a fan of a burner, thefuel system comprises a fuel supply portion and a second proportional directional valve, and the fuel supply portion is connected with a fuel oil nozzle of the burner through the second proportional directional valve. In the air supply system in the method, the valve opening degree of the first proportional directional valve is electrically controlled so as to control the air supply speed and quantity of the burner. In the fuel system, the second proportional directional valve is electrically controlled so as to control the fuel supply quantity of the burner. On the basis of achieving air supply and fuel supply of the burner, the air supply quantity, the fuel supply quantity and the ratio of the air supply quantity to the fuel supply quantity can be accurately controlled, burning economical efficiency is high, and electrical control is easy.

Description

technical field [0001] The invention belongs to the technical field of diesel burner hydraulic control, and more specifically relates to a hydraulic air supply and fuel system of a diesel burner and a use method thereof. Background technique [0002] A diesel burner is a device that converts diesel into heat energy through a combustion chemical reaction. Air and diesel are mixed in an appropriate proportion through a premixing device to make them fully combustible. Diesel burner, as a kind of mechatronics equipment with high degree of automation, is mainly composed of four parts: air supply system, ignition system, monitoring system, fuel system and electric control system; among them, the function of air supply system is to supply The air with a certain wind speed and volume is sent into the air, and the function of the fuel system is to ensure the fuel required for the burner to burn. [0003] At present, the commonly used diesel burners mainly use a strong current power ...
