Pulsers keep blowing due to pressure.
Pumps typically operate at a ratio of approximately 50:1, meaning that a pressure of 40 PSI at the pump translates to 2,000 PSI at the nozzles. The K400 models are designed for an operating pressure of 1,000 PSI, with a maximum bursting pressure of 2,900 PSI.
To minimize the risk of damage to downstream components, it is advisable to set the pump to the lowest possible pressure. A common recommendation is to maintain a ratio of 10:1 at the pump.
The pressure at the pump can be different from the pressure at the K400 Piusi pulse meter, depending on where the meter is installed within the system and how the system is configured. Several factors can influence this difference:
-
Distance from Pump: The further the pulse meter is from the pump, the more likely there is a pressure drop due to friction and resistance in the piping or hose.
-
Pipe/Hose Diameter and Length: Smaller or longer pipes and hoses can increase friction losses, which reduces the pressure by the time the fluid reaches the pulse meter.
-
Fittings and Valves: Any fittings, valves, or bends in the system can also cause pressure drops.
-
Fluid Viscosity and Temperature: Changes in the viscosity of the fluid, often related to temperature, can affect the pressure drop across the system.
To ensure that the pressure at the K400 does not exceed its maximum rated pressure, you might need to install a pressure regulator or use other methods to control the pressure directly before it enters the pulse meter. This setup helps maintain the integrity and accuracy of the pulse meter by keeping its operating conditions within safe limits.
COMPONENT RUPTURE HAZARD
The maximum working pressure of each component in the system may not be the same. To reduce the risk of over-pressurizing any component in the system, be sure you know the maximum working pressure of each component, including the air motor and pump.
Never exceed the maximum working pressure of the lowest rated component in the system. Over-pressurizing any component can result in rupture, fire, explosion, property damage, and serious injury. To determine the fluid output pressure using the air regulator reading, multiply the ratio of the pump by the air pressure shown on the regulator gauge. For example:
10 (:1) ratio x 180 psi air = 1800 psi fluid output
[10 (:1) ratio x 12.4 bar air = 124 bar fluid output]
Limit the air to the pump so that no air line or fluid line component or accessory is over-pressurized.
