หลักการทํางานของpressuregauge has expanded the check vary of its specially developed container take a look at bench to take care of hot or explosive fluids.
The take a look at bench was initially launched in December 2018 but Lewa has thus far solely used water because the conveyed medium for testing and verifying pump features. Many of the fluids Lewa deals with are ranked as supercritical in terms of explosion hazard and worker safety, so the company has now expanded its take a look at range to cowl most of these media.
In addition to an experimental space of explosion safety Zone 1 the place the check experiments take place, the container additionally features a secure control room with out explosion hazard for housing the drive and control tools. Supercritical fluids corresponding to gasoline, methanol, acetone or nitrocellulose thinner are used in the check chamber, whose interior could be seen via gas-tight glass panes, at course of temperatures of up to 80°C and a most amount of 200 l. A high-resolution data recording system ensures correct monitoring and outcomes.
The initial take a look at has been carried out on the system to verify diaphragm clampings for micro-leakage utilizing a low-viscosity fluid and the the Lewa Ecoflow LDG3 sort with an M9 pump head.
