Abstract

The invention discloses a sewage sump for a locomotive fuel tank and an installing method. The sewage sump comprises a blow-off pipe, a cover plate, a U-shaped surrounding plate, a filter net and end plates. The front end and the rear end of the U-shaped surrounding plate are connected with the end plates to form a sump body with an opening formed in the upper end. The bottom of the sump body is connected with the blow-off pipe. The top end of the sump body is provided with the cover plate. An oil leakage hole is formed in the cover plate and internally provided with the filter net. The cover plate is welded and fixed to a partition plate of the fuel tank. The blow-off pipe is matched with a drain outlet in the outer side wall of the fuel tank. The sewage sump is firstly welded into a whole, process shunting of the sewage sump is convenient, flaw detection of weld joints is convenient, and quality control is facilitated. Then, the sewage sump is firstly welded and fixed to a fuel tank body, an upper fuel tank cover plate is installed finally, weld joints of the sewage sump and the upper fuel tank cover plate are arranged on the outer side of the fuel tank body, welding of weld joints of the upper fuel tank cover plate and the sewage sump is convenient, and flaw detection of the weld joints is convenient. The problem that a traditional sewage sump is difficult to assemble in a closed cavity can be effectively solved.

Description

technical field [0001] The invention relates to a dirt collection tank, in particular to a dirt collection tank for a locomotive fuel tank. Background technique [0002] At present, the traditional dirt collection tank of a locomotive is installed and fixed on the inside of the upper cover of the oil tank of the locomotive. The sewage pipe of the sewage tank is aligned with the sewage outlet of the outer plate of the main body of the fuel tank, which is extremely inconvenient to install, and the weld between the sewage collection tank and the upper cover plate is located inside the fuel tank body, which is not conducive to later weld inspection. [0003] Therefore, how to solve the above technical problems has become an urgent problem for those skilled in the art. Contents of the invention [0004] The object of the present invention is to provide a kind of dirt collecting tank and installation method for the oil tank of a locomotive, which can completely solve the above-...
