Abstract

A methodology and solution for controlling the flow rate of relatively low viscosity fluids, such as catalysts, in systems for spraying viscous hydraulic fluids, is provided. A corrective catalyst flow control system, which adjusts the excess air pressure delivered to the catalyst pump in response to changes in nozzle height, is offered. This system is particularly useful for fire-resistant components as it provides efficient and consistent delivery of viscous cementite hydraulic fluid with acidic catalyst.

A third device is arranged on the third axis, intersecting with the main pipe, and is positioned upstream relative to the flow direction from the orifice. This first device introduces a low-viscosity fluid into the supervised fluid at a constant flow rate before the air for dispersion is introduced.

A completed device consistent with claim 7, the first device mentioned above, shall consist of a device for delivering the fluid mentioned above through the pipe mentioned above at a constant flow rate. The device shall consist of a valve connected to a compressed air source and a pump. The valve shall control the flow of air supplied from the compressed air source to the pump, thereby pumping the fluid mentioned above into the pipe mentioned above. 9. A completed device consistent with claim 6, the aforementioned fluid conducting device, shall be an assembly positioned in the flow path of the aforementioned viscous fluid. 10. A completed device consistent with claim 8, the aforementioned fluid conduction device, shall be an assembly positioned in the flow path of the viscous fluid described above. 11.
