Oil nozzles are usually classified according to atomization methods and can be divided into:
(1) Low pressure nozzle This type of nozzle uses the power of combustion air to atomize fuel oil.
. Its advantages are low atomization power consumption and good atomization quality, but its disadvantages are the complex structure of the nozzle itself, limited air preheating temperature, and small nozzle specifications. It is suitable for small heating furnaces without superheated steam
(2) High pressure nozzle oil is atomized using high-pressure superheated steam or compressed air, with good and stable atomization quality. The air supplied for combustion does not directly come into contact with the oil nozzle, so air preheating is not restricted and the adjustment range is relatively large. It is easy to automate in centralized control and air-fuel ratio adjustment. The disadvantage is that the atomizing agent consumes slightly more energy. This type of nozzle is suitable for large and medium-sized heating furnaces or general heating furnaces with superheated steam supply
(3) Mechanical atomization nozzle. The rotary cup type nozzle is a typical mechanical atomization nozzle, which is a high-speed rotating cup-shaped device. The oil in the rotary cup becomes a layer of oil film that is tightly attached to the cup wall, and is then centrifuged out through the cup mouth to atomize.
. This type of nozzle has a complex structure due to its rotating mechanism, and the atomization torch has a large opening angle, so it is rarely used in heating furnaces
Specifications: M10*1、M8*1、M6*1。
Precautions for using oil pump nozzles:
1、 Prohibit the operation of electronic fuel injection pumps in the absence of fuel
2、 The fuel pump nozzle is only used for gasoline fuel products or diesel fuel products with methanol or ethanol content not exceeding 10-15%. If it needs to be used for other fuels, please consult professional staff
3、 If replacing the gasoline pump, it is necessary to replace the filter screen. 90% of gasoline pump failures are caused by long-term accumulation of dirt in the fuel tank. The suction of dirt will reduce the service life of the fuel pump and cause pressure The operator should advise the car owner to clean the fuel tank and corresponding pipelines and accessories in case of a decrease in flow rate
4、 Do not use gasoline pumps that have fallen, otherwise there may be a risk of magnet breakage or broken pins, which will affect the performance of the fuel pump or pose potential hazards such as motor components or oil pipe valves getting stuck
5、 Replace the gasoline filter according to the prescribed time or mileage
6、 When replacing the oil pump nozzle or assembly, the workbench should be kept clean. After all preparation work is completed, open the packaging bag of the new oil pump or assembly with cleaned hands, otherwise it is easy to cause dust Foreign objects enter the oil pump or assembly, affecting normal use
