Spring type buoyancy pressure-resistant cable, manufacturing method thereof and extrusion type fuel cabin

Abstract

The invention provides a spring type buoyancy pressure-resistant cable, a manufacturing method thereof and an extrusion type fuel cabin, and solves the problems that the conventional extrusion type fuel cabin uses a traditional cable to influence the movement of a piston, the piston cannot move to a limit position under the condition of installing a sensor, and the normal use is influenced. The spring type buoyancy pressure-resistant cable comprises a base cable, wherein a pressure-resistant layer and a buoyancy layer are sequentially wrapped outside the base cable from inside to outside, so that the cable is in a suspension state in the extrusion working medium; the cable is in a spring shape with the screw pitch equal to the outer diameter of the cable in a free state; and two ends of the cable are provided with vulcanized watertight electric connectors. The extrusion type fuel cabin comprises a shell, a front cover plate, a rear cover plate, an inner pipe, a piston with a sealing structure and the spring type buoyancy pressure-resistant cable, wherein the spring type buoyancy pressure-resistant cable sleeves the inner pipe, the vulcanized watertight electric connector at one end of the spring type buoyancy pressure-resistant cable is connected with an electric connector of the front cover plate, and the vulcanized watertight electric connector at the other end of the spring type buoyancy pressure-resistant cable is connected with an electric connector of the sensor on the piston.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a spring-type buoyancy pressure-resistant cable, a manufacturing method thereof, and an extruded fuel tank. Background technique [0002] The displacement fuel tank is used to store fuel and provide a displacement pressure not greater than a certain pressure to squeeze the fuel out of the fuel tank; it is mainly composed of a casing, a front cover, a rear cover, a piston with a sealing structure and Composed of inner tubes; the front cover and the rear cover are respectively installed at both ends of the housing; the inner tube is located in the housing and is coaxial with the housing, and its two ends are respectively installed on the front cover and the rear cover; with a sealing structure The piston (hereinafter referred to as the piston) is set on the inner tube; various sensors are arranged on the piston, and the power supply and signal transmission of the sensor ...
