1, flow: when using centrifugal pump, when the connection is constantly wearing, flat fan nozzle under a certain pressure, the flow will usually increase. The flow detection of flat fan nozzle can be measured by measuring the flow meter reading, or by collecting the amount of water sprayed in a certain period of time with a collection method under a given pressure.
2. Spray shape: when the flat fan nozzle is damaged, blocked or bonded, the uneven change of fan spray shape is easy to observe. When the connector gradually wears out, the change of spray shape is not easy to observe until the flow rate increases significantly.
3. Spray pressure: when using centrifugal pump, the spray pressure of flat fan nozzle basically remains unchanged, but the liquid flow usually increases with the wear of nozzle connection. An increase in the flow rate of the flat fan nozzle will result in an increase in the cost of the spray. If the reciprocating pump is used for water supply, the flow rate remains constant, and the jet pressure of the flat fan nozzle will decrease with the wear or corrosion of the nozzle. Low spray pressure reduces spray impact.
4, particle size: with the nozzle wear or corrosion, flow increase, pressure drop, flat fan nozzle to produce larger spray particles.
5. Positive: When multiple flat fan nozzles are installed in a nozzle, a complete uniform coverage is required. All flat fan nozzles are required to be accurately positioned between each other, that is, all fan spray shapes are accurate and positive to ensure accurate coverage area. All sprays should be parallel to each other at a 5° to 10° Angle from the nozzle. Otherwise the coverage would be uneven.
In short, while choosing a flat fan nozzle suitable for their use, we should also pay attention to the maintenance of the nozzle, including regular cleaning of the nozzle internal and external impurities. If you want to know about flat fan nozzles, don't go to the flat fan nozzle center of this website to have a look, there are many kinds of flat fan nozzles for you to buy.
