Glass wool measuring tool for filling insulation box of LNG thin film type maintenance system

Abstract

The invention discloses a glass wool measuring tool for filling an insulation box of an LNG thin film type maintenance system. The glass wool measuring tool comprises a supporting platform, a front baffle, a rear baffle, a capacitive grating displacement sensor, a pressure sensor and a digital display instrument; and the front baffle and the rear baffle are both arranged on the upper end face of the supporting platform, one end of the sliding guide rail extends to the rear baffle, the front baffle is installed on the sliding guide rail in a sliding mode, the digital display instrument is mounted on the supporting platform, a main grid of the capacitive grid displacement sensor is installed on the rear baffle, an auxiliary grid of the capacitive grid displacement sensor is installed on thefront baffle, the main grid and the auxiliary grid are respectively connected with the digital display instrument through signal cables, a pressure sensor is installed on the front baffle, and the pressure sensor is connected with the digital display instrument. The method can effectively solve the problem that the calibration error of the filling size of the glass wool for filling the insulationbox of the thin film type enclosure system is large, and the filling quality and efficiency of the glass wool are improved.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a glass wool measuring tool for filling an insulating box of an LNG film-type maintenance system. Background technique [0002] At present, large LNG carriers in the world mainly adopt NO96 film type containment system. The heat insulation of this type of containment system mainly depends on the insulation box installed in the hull, and the insulation box is filled with glass wool. Glass wool is easy to compress and deform. In order to ensure that the filling effect of glass wool in the insulation box meets the requirements, it is necessary to determine the actual filling size requirements of glass wool according to different suppliers, different product densities and compression elasticity. [0003] The insulating box of NO96 film type containment system is divided into various types. The length, height, width and partition spacing of each type of insulating box...

AI Technical Summary

Problems solved by technology

[0003] The insulating box of NO96 film type containment system is divided into various types. The length, height, width and partition spacing of each type of insulating box are different. The specification, size and number of layers of glass wool need to be determined according to the box type. During the cotton filling process, the front and rear sealing plates and spacer plates of each box type have different frictional resistances to the glass wool. Therefore, the glass wool measurement needs to cover the corresponding different specifications and sizes, and the size calibration and testing under different pressures. There is a lack of equipment that can greatly reduce the unqualified rate of glass wool cutting and significantly improve the efficiency and quality of glass wool filling
