A pressure washer is used to remove old paint from a boat. Patio flagstones being pressure washed using a rotary nozzle. Pressure washing or power washing is the use of high-pressure water spray to remove loose paint, mold, grime, dust, mud, and dirt from surfaces and objects such as buildings, vehicles and concrete surfaces.
A direct drive pump works much like a car engine, forcing water through high-pressure tubing using plungers attached to a crankshaft. An intensifier pump creates pressure by using hydraulic oil to move a piston forcing the water through a tiny hole. [37] [38] The water then travels along the high-pressure tubing to the nozzle of the waterjet ...
The most common causes are accidents with grease guns, paint sprayers, and pressure washers, but working on diesel and gasoline engine fuel injection systems as well as pinhole leaks in pressurized hydraulic lines can also cause this injury. Additionally, there is at least one known case of deliberate self-injection with a grease gun. [2]
A parts washer is distinctly different from a pressure washer in that parts washers typically clean parts automatically in an enclosed cabinet, while pressure washers typically have a single spray jet mounted at the end of a manually operated wand. Modern industrial technology makes it possible to combine many parts of the finishing process ...
Refinements made with Larami design director William Raucci and engineering consultant Bruce D'Andrade made its mass production feasible, [2] and the first commercial version of the water gun appeared in stores the following year as the Power Drencher. In 1991 it achieved commercial success under its new name, Super Soaker.
As with their air-actuated cousins, powder-actuated guns have a muzzle safety interlock. If the muzzle is not pressed against a surface with sufficient force, the firing pin is blocked and cannot reach the load to fire it. This helps ensure that the gun does not discharge in an unsafe manner, causing the nail to become an unrestrained projectile.
Autofrettage is a work-hardening process in which a pressure vessel (thick walled) is subjected to enormous pressure, causing internal portions of the part to yield plastically, resulting in internal compressive residual stresses once the pressure is released. The goal of autofrettage is to increase the pressure-carrying capacity of the final ...
In 2000, it opened its second plant for the production of firearms and pressure weapons in the city of Montenegro, in the state of Rio Grande do Sul, and in the respective years of 2007 and 2009, it acquired the European manufacturers of ammunition and supplies Sellier & Bellot and MEN, besides investing in the production of ammunition outside ...
