Problems solved by technology

[0004] Aiming at the above-mentioned technical problems, the present invention provides a cold distribution pipeline method for the oil tank, which can solve the problem that the high-quality lubricating oil in the oil tank belongs to Inflammable and explosive products, the current method of fire welding and drilling is likely to cause explosions, and the method of dismantling and dismantling the main fuel tank and then processing it separately is time-consuming, labor-intensive and has a long construction period, and the upper space of the fuel tank is small. It is also not suitable for drilling with a pistol drill

Embodiment Construction

[0014] A fuel tank cold distribution pipeline method, comprising the following steps:

[0015] a. Attach the magnetic drill to the upper part of the fuel tank, and use a φ14.5 drill bit to drill holes in the fuel tank;

[0016] b. Use an M16 tap to tap the hole punched in step a;

[0017] c. Install the DN65 flange on the round hole tapped in step b, and pipe;

[0018] d. Send a strong magnet into the oil tank, absorb iron filings and take them out several times. After checking the oil quality of the lubricating oil, it is confirmed that the iron filings are completely removed, and finally the oil pipeline is installed with the flange.

Abstract

The invention discloses an oil tank cold distribution pipeline method, which comprises the steps of a, attracting a magnetic drill to the upper portion of an oil tank, and punching the oil tank by adopting a drill bit; b, tapping the hole punched in the step a by adopting a screw tap; c, mounting a flange on the round hole tapped in the step b, and mounting a distribution pipe on the flange; and d, feeding a powerful magnet into the oil tank, attracting scrap iron and then taking the scrap iron out by multiple times, determining that the scrap iron is completely removed through lubricating oilquality inspection, and finally, mounting an oil pipeline in a mode of being matched with the flange. The method disclosed by the invention solves the problems that when the upper part of the oil tank is punched to install a smoke ventilator or modify an oil cooling system on a converter fan at present, the currently adopted fire welding punching mode is easy to cause explosion due to the fact that the high-quality lubricating oil in the oil tank is a flammable and explosive product, the mode of separate operation after disassembling the main oil tank is time-consuming and labor-intensive, and the upper space of the fuel tank is narrow and not suitable for drilling with a pistol drill.

Description

technical field [0001] The invention relates to the technical field of punching methods, in particular to a method for cold distribution pipelines of an oil tank. Background technique [0002] The 2# converter fan in the power center of the copper company needs to drill holes in the upper part of the oil tank, install DN65 flanges and pipe 2 pieces when installing the smoke exhauster and the oil cooling system renovation. However, there is a problem during installation, because the main oil tank stores high-quality lubricating oil, which is flammable and explosive. If fire welding is used, the high-temperature acetylene flame can quickly ignite the lubricating oil. If high-temperature welding slag falls into the oil tank using electric welding, it can Igniting the lubricating oil will affect the quality of the lubricating oil. In severe cases, the fuel tank may explode. Therefore, fire welding operations cannot be used on the upper part of the fuel tank. Another method is t...
