Method for Testing the Spray Flammability of Hydraulic Fluids

SAE Technical Paper Series, 1992
<div class="htmlview paragraph">This paper presents the results of a study undertaken at Factory Mutual Research Corporation (FMRC) to quantify the spray flammability of hydraulic fluids. Spray flammability characteristics of several commercially available hydraulic fluids, mineral oils, methanol, ethanol, and heptane, sprayed vertically upward ...

A method for testing the flammability of sprays of hydraulic fluid

Fire Safety Journal, 1992
Abstract A method for testing the flammability hazards of hydraulic fluids in the form of spray escapes, is described. The method utilizes sprays, produced by a twin-fluid atomizer, which are ignited at their roots by the carefully controlled input of heat from a gas flame.

Repair of hydraulic structures with sprayed concrete

Hydrotechnical Construction, 1968
1. The restoration of concrete surfaces with sprayed concrete is an efficient, highly mechanized, and comparatively economical method; and the work is of high quality. 2. The described method may be expeditiously employed in repairing surfaces while operating the structures; for example, in repairing lock chamber walls while operating ...

Spray Flammability of Hydraulic Fluids

1996
The spray flammability characteristics of several hydraulic fluids, and mineral oil, methanol, ethanol, and n-heptane, sprayed vertically upward in the open through a pressure-jet hollow cone nozzle and stabilized by a propane-air ring burner, have been evaluated using the Factory Mutual Research Corporation (FMRC) Fire Products Collector.

A Spray Flammability Test for Hydraulic Fluids

1960
A serious threat to life and property in many industries is the hazard of a pressurized hydraulic line rupturing, causing the escaping fluid to enter the flame of a fuel burner. The test described here simulates this danger and evaluates the fire resistance of hydraulic fluids under such conditions.

A Simplified Spray-Flammability Test for Hydraulic Fluids

1966
Hydraulic lines are known to rupture permitting a stream or spray of hydraulic fluid to encounter the flame of burning fuels or the surface of hot or molten metal. This is a prevalent cause of fires in many industries. High-pressure spray-flammability tests simulate this type of industrial hazard and are able to distinguish the difference in fire ...

Spray Penetration into Peanut Canopies with Hydraulic Nozzle Tips

Biosystems Engineering, 2004
Abstract The spray penetration into peanut canopies with single- and twin-row planting systems at three growth stages was investigated with four different types of hydraulic nozzle tips (flat fan, hollow cone, twin jet and air induction). The nozzles were operated at 276 kPa pressure, 6·4 km h−1 travel speed, and 0·5 m above the top of canopies.

Spray distribution by hydraulic low-pressure fan spray nozzles fitted with a pellet

Journal of Agricultural Engineering Research, 1965
Abstract An improvement in distribution was obtained by a pellet of 3·7 mm dia inserted inside a fan spray nozzle. Experiments were carried out with individual, low pressure nozzles of 73° spray angle and three sizes, using water as spray liquid. The uniformity of spray distribution was estimated by the coefficient of variation.

A simulation model of the spray drift from hydraulic nozzles

Journal of Agricultural Engineering Research, 1989
Abstract A model to predict the trajectories of droplets from agricultural flat fan nozzles is described. Droplet motion is considered in two phases: close to the nozzle where the trajectory is dominated by the conditions associated with droplet formation, particularly the initial velocity and entrained air conditions; and a second phase where the ...

Automatic Atomized Water Spray System for Soil Hydraulic Conductivity Measurements

Soil Science Society of America Journal, 1994
Abstract Soil hydraulic conductivity, K , as function of volumetric water content, θ, must be known accurately for any quantitative investigation of water and solute transport in unsaturated soil.
