Abstract

The invention discloses a fuel oil filter applied to a gas turbine. The fuel oil filter applied to the gas turbine includes a filter shell body, the filter shell body is provided with an inlet main pipe and an outlet main pipe, the inlet main pipe is correspondingly connected with one ends of two stop valves installed in the filter shell body, the other ends of the stop valves are connected to thebottom ends of filter drums, filter elements are arranged in the filter drums, and the upper ends of the filter drums are connected to one ends of check valves through filter covers, the other ends of the check valves are connected with the outlet main pipe, the number of the filter drums, the filter elements, the filter covers and the check valves are all two, and the filter drums, the filter elements, the filter covers and the check valves are all symmetrically arranged in the filter shell body. According to the fuel oil filter applied to the gas turbine, the problems of a large size, poorreliability, high noises during vibration, no shock and vibration resistance design and the like of an existing filter structure are solved, and the requirements of filtering performance, a compact structure, on-line switching and replacement of the filter elements, shock and vibration resistance, high reliability and the like of a gas turbine fuel oil system are met.

Description

technical field [0001] The invention relates to a fuel filter applied to a gas turbine. Background technique [0002] The existing dual structure of conventional fuel oil filter equipment has the disadvantages of large volume and poor shock and vibration resistance. Gas turbine dual filter equipment has put forward requirements such as compact structure, online switching and replacement of filter elements, shock resistance and high reliability. Contents of the invention [0003] The purpose of the present invention is to provide a fuel filter applied to gas turbines, which solves the problems of large volume and poor shock and vibration resistance in the existing conventional double-connected structure of fuel filter equipment. It has a compact structure and can be switched and replaced online. , Shock and vibration resistance, high reliability. [0004] The technical solution adopted to achieve the above purpose is that a fuel filter applied to a gas turbine includes a f...
