The invention discloses a cleaning, de-rusting and
cutting automatic conversion all-in-one
machine for an offshore oil platform. The cleaning, de-rusting and
cutting automatic conversion all-in-one
machine for the offshore oil platform comprises a jewel orifice, a spraying gun
handle, a high-pressure rubber
pipe, a sand amount adjustment
handle, a
protective shield, an end cover, a pressure
relief valve, a liquid
inlet pressure gauge, a
work pressure gauge, a pressure flow amount control valve, a pushing
handle, a high-pressure liquid inlet
pipe, a base, a trundle, a one-way valve, a
balance water adjustment button, a mixing valve
assembly, a supporting leg, an
abrasive tank and other parts. After pressure water is subjected to pressure flow amount adjustment through the pressure flow amount control valve, the pressure water enters the mixing valve through the high-pressure liquid inlet
pipe. Abrasives in the
abrasive tank enter the mixing valve, are mixed with the water and then enter the jewel orifice through the high-pressure rubber pipe. The jewel orifice accelerates the mixed water and sprays the water on an object on the platform. The function of automatic conversion of cleaning, de-rusting and
cutting is realized by adjusting the
diameter of the jewel orifice.
