Oil mass testing method of liquid lubricating oil for coating surface of enamelled wire

Abstract

The invention discloses an oil mass testing method of liquid lubricating oil for coating the surface of an enamelled wire. The oil mass testing method comprises the following concrete steps: 1) preparing materials; 2) selecting a filter paper, and cutting the paper towards the circle center along the edge of the filter paper; 3) preparing a pencil; 4) fixing two ends of a specimen in a suspending manner; 5) firstly, locking the enamelled wire at the end point of a paper cutting tangent line of the circular filter paper after processing the liquid lubricating oil, and then enabling the filter paper at two sides of the tangent line to intersect, so as to ensure that the periphery of the enamelled wire contacts the paper filter; 6) firstly, holding the crossed part of the filter paper along a running direction, and then moving the filter paper; 7) moving the filter paper to the specified length, and then placing the filter paper for corresponding time, so that the liquid lubricating oil infiltrates the filter paper; 8) drawing up the boundary of the part of the lubricating oil infiltrated by the filter paper by the pencil, and taking one half of the sum of the maximal diameter and the minimal diameter of the drawn boundary as oil mass; 9) recording the oil mass, and 10) determining an operating parameter of an oiling mechanism according to the obtained oil mass. By adopting the oil mass testing method, the oil mass of the liquid lubricating oil for coating the surface of the enamelled wire is tested in a most reasonable manner according to the characteristics of the liquid lubricating oil for coating the surface of the enamelled wire.

Description

technical field [0001] The invention relates to the field of methods for detecting the amount of liquid lubricating oil for enameled wires, in particular to a method for testing the amount of liquid lubricating oil for enameled wire surface coating. Background technique [0002] At present, more and more enameled wire production processes use the equipment described in Patent No. CN201120469923.3 to complete the enameled wire coating by attaching liquid lubricating oil to the surface of the enameled wire, so that the lubricating oil can be evenly coated on the surface of the enameled wire. Different enameled wires have different requirements for liquid lubricating oil. In order to obtain enameled wire with better coating effect, it is necessary to detect the amount of liquid lubricating oil used to obtain the best operating parameters of the oiling mechanism. At present The detection method of liquid lubricating oil for enameled wire processing is often unreasonable, and the...

[0002] At present, more and more enameled wire production processes use the equipment described in Patent No. CN201120469923.3 to complete the enameled wire coating by attaching liquid lubricating oil to the surface of the enameled wire, so that the lubricating oil can be evenly coated on the surface of the enameled wire. Different enameled wires have different requirements for liquid lubricating oil. In order to obtain enameled wire with better coating effect, it is necessary to detect the amount of liquid lubricating oil used to obtain the best operating parameters of the oiling mechanism. At present The detection method of liquid lubricating oil for enameled wire processing is often unreasonable, and there is no unified standard in the industry. Therefore, there is an urgent need for a more standardized liquid lubricating oil detection method for enameled wire processing to detect the amount of liquid lubricating oil to obtain the best Operating parameters of oiling mechanism
