Abstract

An oil starvation alarm system of a roller system of a cold rolling mill comprises an engine block mill, an oil inlet tube, first flow detection devices and an alarm device, wherein a plurality of bearings are arranged on the engine block mill, oil inlets and oil outlets are arranged in the bearings, one end of the oil inlet pipe is connected onto the oil inlets, the other end of the oil inlet pipe is connected with an oil pump, each oil outlet is connected with one first flow detection device, and when the first flow detection devices detect that the flow is lower than a set value, the alarm device sends out an alarm. The first flow detection devices are arranged at the oil outlets and can accurately measure the quantity of oil liquid passing through the bearings so as to prevent the burning out of the bearings.

Description

technical field [0001] The invention belongs to the technical field of cold rolling mills, in particular to an oil shortage alarm system for cold rolling mill rolls. Background technique [0002] Cold rolling mills bear heavy loads during work, so the bearings of the rolls must maintain good lubrication and heat dissipation conditions, which requires injecting oil, gas or oil into the bearings to ensure the lubricity of the bearings and take away the heat in the bearings. If the oil gas or oil cannot enter the bearings of the cold rolling mill rolls according to the specified scalar amount, it will cause the bearings of the roll system to burn out, ranging from a loss of more than 100,000 yuan to more than 200,000 yuan. [0003] Therefore, it is generally adopted to install a flow detection device at the oil gas or oil input of the cold rolling mill to detect the amount of oil gas or oil output by the oil pump. Once the oil gas or oil output by the oil pump is lower than the...
