How to change desired flow rate of the nozzle

In summary, the conversation discusses the possibility of manually changing the flow rate of one nozzle connected to a 70 bar pump with 9 nozzles. A pressure regulator valve can be used to reduce the flow rate, but it is not possible to increase it. The attached diagram shows the effect of flow rate on bead size, where a higher flow rate results in a larger bead.

Hello,

We have a system with a 70 bar pump and 9 nozzles connected to the pump lines. Total flow rate is 2 l/m. Is there a way to change only one nozzle flow rate manually, with a pressure regulator valf just behind that nozzle?

Thank you.

Hello icy, :welcome:

I suppose 'behind' is relative. With a valve between the pump and the nozzle you should be able to reduce the flow rate. Increasing it would be rather impossible :smile:

Hello BvU,

You may see the attached file. It is a simple diagram to see what we need. Can you make a new comment according to the file?

Thank you.

BvU's existing comment, as stated, still applies.

Stream rate directly affects bead estimate. An expansion in stream rate will build the bead measure; comparatively, an abatement in stream rate will diminish bead estimate.

Case: A 150 gpm empty cone spout at 10 psi has a bigger bead than a 100 gpm empty cone at 10 psi. Likewise, a 50 gpm full cone spout at 7 psi has a littler bead estimate than a 120 gpm full cone spout at the same weight.
 

Related to How to change desired flow rate of the nozzle

1. How do I adjust the flow rate of a nozzle?

To adjust the flow rate of a nozzle, you can either use a flow control valve or a flow restrictor. The flow control valve allows you to manually adjust the flow rate by opening or closing the valve. A flow restrictor, on the other hand, limits the flow rate by restricting the amount of fluid passing through the nozzle.

2. What is the ideal flow rate for a nozzle?

The ideal flow rate for a nozzle depends on the specific application and the type of nozzle being used. In general, it is recommended to start with a lower flow rate and gradually increase it until you achieve the desired results. It is important to note that a higher flow rate does not always mean better performance, as it can lead to overspray and waste of resources.

3. How can I calculate the flow rate of a nozzle?

The flow rate of a nozzle can be calculated by multiplying the cross-sectional area of the nozzle by the velocity of the fluid passing through it. This calculation can be done using the formula Q = A x V, where Q is the flow rate, A is the cross-sectional area, and V is the fluid velocity. The units of flow rate are typically measured in gallons per minute (GPM) or liters per minute (LPM).

4. What factors can affect the flow rate of a nozzle?

There are several factors that can affect the flow rate of a nozzle, including the pressure of the fluid, the size and shape of the nozzle, and the viscosity of the fluid. Additionally, any obstructions or clogs in the nozzle can also impact the flow rate. It is important to regularly check and maintain your nozzle to ensure consistent and accurate flow rates.

5. Can I change the flow rate of a nozzle without replacing it?

Yes, the flow rate of a nozzle can be adjusted without having to replace it. As mentioned earlier, you can use a flow control valve or a flow restrictor to change the flow rate. However, if you find that the desired flow rate cannot be achieved with these methods, it may be necessary to replace the nozzle with one that is better suited for your application.
