Description

Technical Field

[0001] The invention belongs to the field of oil and gas lubrication, and in particular relates to a novel intelligent oil and gas lubrication satellite station. Background Art

[0002] With the continuous improvement of the degree of industrialization, traditional lubrication technology can no longer adapt. Oil-gas lubrication is a newly developed gas-liquid two-phase fluid cooling lubrication technology. It is more suitable for high temperature, heavy load, high speed, extremely low speed and harsh working conditions with cooling water and dirt invading the lubrication points. It greatly extends the service life of the friction pair and improves the on-site environment. Therefore, it is more and more widely used in the metallurgical industry.

[0003] In the rolling mill equipment of steel and strip steel, there are two common oil supply designs. Usually, a satellite station provides lubricating oil for the bearing seat and bracket device of the nearest rolling mill at the same time, or a satellite station provides oil source for the bracket device or the rolling mill alone. The second configuration pipeline is too long, which is not conducive to on-site monitoring and maintenance. Each satellite station oil outlet pipe is connected to a bearing seat lubrication point.

[0004] The crude oil gas lubrication satellite station realizes oil distribution by setting the oil supply time (seconds / S) and the number of oil supply times (times / CY). After the oil supply parameters are set, the distributor branches will discharge oil in sequence, but the oil volume of each outlet cannot be adjusted separately. The bracket bearing seat uses less oil than the rolling mill bearing seat. The amount of lubricant required for each rolling mill at different operating speeds is also different. If the oil supply of each branch cannot be adjusted separately, the bracket or most of the bearing seats will have excess oil supply, resulting in a waste of resources and costs.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0035] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0036] The new intelligent oil and gas lubrication satellite station includes:

[0037] An air circuit component, wherein the air inlet end of the air circuit component is connected to an external air pump, and the air outlet end of the air circuit component is connected to a mixing component;

[0038] An oil circuit assembly, wherein the oil inlet end of the oil circuit assembly is connected to an external oil pump, and the oil outlet end of the oil circuit assembly is connected to a mixing assembly;

[0039] A mixing component is provided with a plurality of connecting branches, each connecting branch is connected to a bearing seat, and all connecting branches are connected to the air circuit component and the oil circuit component.

[0040] The air circuit assembly is connected in sequence with a manual ball valve, a two-position two-way solenoid valve, a water vapor filter, a gas pressure gauge, an air pressure regulating valve, and a differential pressure switch; the end of the manual ball valve away from the two-position two-way solenoid valve is connected to an external air pump; the differential pressure switch is used to detect the pressure of compressed air, and when the pressure is lower than 2 bar, an alarm (air pressure lower than 2 bar fault) is given.

[0041] The oil circuit assembly is sequentially connected with a high-pressure ball valve, an oil pressure gauge, an oil filter, a throttle valve, a main circuit solenoid valve, and a quantitative metering distribution block; one end of the high-pressure ball valve away from the oil pressure gauge is connected to an external oil pump.

[0042] A gas passage and multiple oil passages are provided in the mixing component; one end of the gas passage is connected to the gas passage component, and the other end is connected to all connecting branches; the oil passages correspond to the connecting branches one by one, one end of the oil passage is connected to the oil passage component, and the other end is connected to the corresponding connecting branch.

[0045] When there is a pressure difference between the inlet and outlet of the quantitative metering distribution block, the distributor located in the quantitative metering distribution block starts to work and discharges the oil into the mixing assembly. The distributor operates once and discharges a fixed 0.48 ml of oil. When the proximity switch detects the set number of working times, the reversing valve at the inlet is closed and the oil stops flowing. The distributor is specifically: a centralized lubrication distributor.

[0046] The working and interval time of the quantitative metering distribution block is determined by the total oil consumption of all bearings in the area under the jurisdiction of the master station, and the working cycle and number of each branch are set accordingly.

[0047] After the oil and gas main station is started, open the manual ball valve and the high-pressure ball valve. When the set working cycle time is reached, the main oil valve opens, and the lubricating oil with a certain pressure enters the quantitative metering distribution block. The distributor in the quantitative metering distribution block starts working, and the proximity switch starts counting. At the same time, the first branch solenoid valve opens. After completing the set number of working times, the main and first branch solenoid valves are automatically closed. After an interval of 5S (the time can be set manually), the main and second branch solenoid valves are opened. After completing the set number of working times, the main and second branch solenoid valves are automatically closed. Repeat the above steps until a working cycle is completed, and then enter the interval cycle. After completing a complete working cycle, prepare for the next working cycle.
