Embodiment 1

[0044] seefigure 1 , this embodiment provides a roll lubrication system monitoring and control device, including temperature detection equipment, constant temperature oil storage system and control system; wherein,

[0045] The constant temperature oil storage system is connected to the lubricating oil inlet 101 and the lubricating oil outlet 102 of the target roll 1 through pipelines, so that the lubricating oil can circulate between the target roll 1 and the constant temperature oil storage system flow, keeping the lubricating oil liquid level in the target roll 1 within the preset liquid level interval value;

[0046] The constant temperature oil storage system is also used to adjust the temperature of the lubricating oil;

[0047] The temperature detection device is used to detect the temperature information of the lubricating oil in the target roll 1;

[0048] The control system is used to control the constant temperature oil storage system to adjust the temperature of t...

Embodiment 2

[0070] In addition, in order to protect the surface quality of the rolled steel plate, the emulsion is sprayed on the surface of the steel plate, which will easily cause water seepage in the bearing housing, reduce the lubrication of the roll bearing, and easily damage the roll bearing. The liquid level of the lubricating oil in the roll bearing seat of the rolling mill is too high, the resistance is large, the efficiency is low, and leakage is easy to occur, thereby affecting the surface quality of the steel plate and polluting the environment.

[0071] Therefore, on the basis of Embodiment 1, in order to deal with the situation of water ingress in the lubricating oil in time, and recycle it, without causing environmental pollution, see figure 1 , the device also includes:

[0072] water content detection equipment, electrically connected to the control system, for detecting water content information of the lubricating oil in the target roll 1, and sending the water content i...

Embodiment 3

[0079] The liquid level of lubricating oil in the roll bearing housing is too high, the amount of lubricating oil is too large, and the resistance is large, which reduces the efficiency of the rolling mill and is prone to lubricating oil leakage, which affects the quality of the rolling emulsion, thereby affecting product quality and polluting the environment; while the roll The liquid level of the lubricating oil in the bearing seat is too low, the amount of lubricating oil is too small, the temperature of the lubricating oil rises, the lubrication effect is poor, the bearing is easily damaged, and the life of the rolling mill is reduced.

[0080] Therefore, on the basis of embodiment one, see figure 1 A first flow control valve 134 is arranged on the pipeline connected between the constant temperature oil storage system and the lubricating oil inlet 101 of the target roll 1, and the constant temperature oil storage system is connected with the lubricating oil outlet 102 of th...

Abstract

The invention discloses a monitoring and controlling device of a roller lubricating system. The device comprises a temperature detecting device, a constant-temperature oil storage system and a controlsystem, wherein the constant-temperature oil storage system is connected with a lubricating oil inlet and a lubricating oil outlet of a target roller through pipelines, so that the lubricating oil can circularly flow in the target roller and the constant-temperature oil storage system, and the lubricating oil level in the target roller is kept within a preset liquid level interval value; the constant-temperature oil storage system is also used for adjusting the temperature of the lubricating oil; the temperature detection device is used for detecting the temperature information of the lubricating oil in the target roller; and the control system is used for controlling the constant-temperature oil storage system to adjust the temperature of the lubricating oil according to the temperatureinformation of the lubricating oil in the target roller, so that the temperature of the lubricating oil in the target roller is within a preset temperature interval value. The device solves technicalproblem that the service life of the roller is decreased due to the fact that the roller lubricating oil is not monitored and controlled in place.

Description

technical field [0001] The invention relates to the technical field of steel rolling equipment maintenance, in particular to a monitoring and control device for a roll lubrication system. Background technique [0002] Rolling mill is the main equipment in the process of metal processing in the metallurgical industry. The roll is an important part of the rolling mill, which is mainly composed of rolls, bearings, bearing housings, etc. The inside of the bearing seat is lubricated and cooled by lubricating oil, so as to reduce the wear in the bearing seat and increase the service life of the roll. However, under the existing rolling mill production conditions, various factors cause abnormality of lubricating oil in the bearing housing, for example, the level of lubricating oil is too high or too low, and the temperature of lubricating oil is too high. [0003] In the prior art, the lubricating oil level can be replenished in time, but there is basically nothing to do about th...
