Disposal technique introduced in hydrostatic test for fire hoses

摘要

Disposal technique introduced in hydrostatic test for fire hoses.The utility model relates to the technical provision introduced in hydrostatic test for fire hoses, (1), characterized by being composed of a semi-trailer (2); a nitrogen cylinder (3); water cylinder (4); backup (5) of water; pump motor (6); tanq The EU (7) of water, highlighting that the semi-trailer (2) has three cylinders, mounted on skids (9),Which is a nitrogen cylinder (3), a water cylinder (4) and a cylinder (5) is water. The tubing (12) is fixed on the floor of the body of the semi-trailer (2) connected to a motor pump (6) of 7.5 HP, with a water tank (7) and on the other, three couplers (13) for fire hoses (8).The pump motor (6) recalca water tank (7) to the pipeline (12), and get it in the three fire hoses (8).The pump motor (6) is turned off and the valves (14) of the nitrogen cylinder (3) and water (4), are driven by releasing the gas, flowing through the hose (15), until the water cylinder (4), propelling the water to the pipe (12). Valves (10) opened and valve (11) closed until the MA Ngueiras (8), to achieve the test pressure.A valve (17) is open to the bike pump (6) to feed the water consumed by the water cylinder (4), leaving the valve (18) opened to release air from the cylinder of the water.
