Multiple decisions play a role in maximizing efficiency during the process of cleaning commercial tanks and equipment. Choosing to use spray nozzles instead of manually cleaning is important. Selecting the ideal tank cleaning device for your application is equally critical. Rotating or static? Which nozzle is best for a tank of my size and how many nozzles should I use?
However, once you’ve determined the very best option for your application, maximizing cleaning efficiency is not over. Specific details, such as pressure and impact, are equally important for optimal efficiency. Below, we explore one seemingly small, yet important aspect in tank and equipment cleaning: operating pressure and how it relates to spray impact.
Impact and Pressure
When cleaning the internal surface area of a tank, rotating cleaning nozzles deliver the greatest cleaning efficiency. When ran properly these nozzles are able to produce large droplets which strike the sides of the tank at high speeds. This is achieved when two dynamic factors work simultaneously: operating pressure and the distance between the nozzle and the internal surface of the tank.
For rotating nozzles, pressure and impact have no linear relationship. Supply pressure simply influences rotation speed. Increased pressure equates to increased rotation speed. As counterintuitive as it may seem, higher pressure is not always ideal, because higher pressure does not equate to higher impact. In fact, if operating pressure or distance between nozzle and surface are too great, the fluid will break down into smaller droplets, similar to a mist.
Examining Recommended Pressure and Maximum Impact
Lechler nozzles are designed to operate with optimum impact at the right operating pressures. Some function under high pressure, others operate under lower pressures. Below, we examine various operating principles for a few specific nozzles, along with their ideal operating pressures.
Free-spinning nozzles are powered by the cleaning fluid. The spray head rotates as the fluid sprays, producing rapid-repetition impact, excellent for washing dirt from tank surfaces. This effect is best picacomic官网地址achieved at low pressures. A small selection of free-spinning nozzles that operate with incredible impact at low pressures include:
