Whether the atomization level is good or not, the performance of the nozzle is very important
In the spray apparatus, whether it is a spray machine with complex structure or a spray machine with intuitive structure, its basic structural units include liquid medicine tank, pressure pump, liquid medicine pipe, spray bar and nozzle. The nozzle is the most critical component, which indirectly restricts the atomization level of spray. No matter its shape, material or internal structure, it needs careful design and optical manufacturing. According to the type and performance of the sprinkler, there are exact techniques to control when spray in the field.

What are the ways to improve nozzle atomization
According to the atomization mechanism and experimental research, and in combination with the on-site use experience in coal mines, the main ways to improve the atomization of nozzles are as follows
Introduction to Atomizing Nozzle
Classification by fog flow shape According to the shape of mist flow formed by the nozzle, the nozzle can be divided into two categories: conical solid nozzle and conical hollow nozzle. The solid nozzle is mainly used for dust suppression, and the hollow nozzle is mainly used for dust suppression.
Influence factors between atomizing nozzles
Pressure type nozzle When pressure type atomizing nozzles (direct and centrifugal) are used to implement spray dust reduction, the dust reduction efficiency mainly depends on the water supply pressure for the determined application occasions.
Atomization Characteristics of Atomizing Nozzle
Atomization characteristics refer to the influence of nozzle structure, working parameters, physical properties of atomizing agent and atomizing medium on the atomization performance of the nozzle. In order to comprehensively evaluate the atomization performance of the nozzle, a number of index parameters are proposed, mainly including: atomization fineness, atomization uniformity, and atomization cone angle.
Introduction to atomizing nozzle
Nozzle is one of the most important parts of combustion equipment. The combustion of liquid fuel generally uses nozzle, and the nozzle design has a great impact on the combustion of liquid fuel.
Explanation of atomizing nozzle mechanism
The atomization process of the nozzle is mainly controlled by four forces, namely aerodynamic resistance, viscous force, liquid surface tension and inertial force. The interaction between these four forces makes the continuous liquid injection split and broken. The atomization process of the nozzle is generally divided into jet atomization process and liquid film atomization process.
