Posted by Switches that detect changes in pressure inside a pump are not novel technology. Miniature centrifugal and diaphragm pumps with modest horsepower have had them for years. Dependable pressure switches for a commercial high-pressure pump with much greater power, such as a 30 Amp motor or more extensive, are considerably more challenging. The pressure settings of a pump may be detected using a pressure switch or an electromechanical sensor. A pressure switch turns off the pump when the pressure reaches a certain level. When the pressure drops below the threshold, the motor will restart. When the spray gun trigger is released, pressure rises, and the sensor knows it’s time to turn off the pump. These are the top three gains from installing a pressure switch on a pump that runs on batteries.
Battery Life Is Much Longer
Long pauses or transitions between spray timings are necessary for specific high-pressure pump applications, which are also high-power. A pressure switch will turn off the power to the motor so that the battery will only run down if used. It is beneficial for pumps with larger motors, which use more power and may quickly deplete a battery if kept on continuously. Even while it has a more extended battery life, you’ll give up a lot of power if you go that route. Several 12V pumps now have switches, so you can get the performance you need without sacrificing battery life.
Ease And Efficiency In The Use
When not spraying, the operator must manually turn the pump on and off if there is no pressure switch. They may save time charging the pump if they leave it on while it is not in use. Both are inconvenient and increase the time and money needed to complete a task.
The Durability Of Pumping Systems
A pump system experiences less wear and tear the fewer hours it is used. Even though most pump systems have a regulator that switches to bypass mode, a pressure switch may significantly increase the longevity of a pump motor. A regulator needs more pressure to go into bypass mode, so if you have a 30 A sprayer and let off of the trigger, the amp draw will increase by a few. If you install a pressure switch, the power to the system will be switched off, preventing the current surge and the resulting wear and tear increase. In addition, you’ll have complete control over the power with which you spray.
Where a Pump Pressure Switch Is Typically Used
To function correctly, a pressure switch is only necessary for some pumps. A pressure switch may not be necessary for a pump used in a patio mister, which operates continuously for lengthy periods. However, switches shine in contexts where machinery must be started and stopped often. For instance, the engine of a portable toilet may be turned off between cleanings, making it ideal for use in a multi-unit complex. Other mobile applications where a pump motor may need to stay idle for lengthy periods include a soft wash sprayer for washing the outside of a building, pest control sprayers, and others.
Conclusion
In particular, nozzle size is an area where operators must pay attention while setting up the pump system. If the nozzle is too tiny, the pressure may not decrease enough, triggering the pressure switch’s on/off cycling. Regarding pressure switches for pumps, one size does not fit all. They must also be compatible with the chemicals and motors and pumps’ rated volts/amps.
