Description

Technical Field

[0001] The utility model relates to the field of grease oil supply, in particular to a bearing chamber precision oil supply system. Background Art

[0002] With the progress of society and the development of science and technology, mechanical equipment has gradually replaced traditional manual labor. There are many bearing chambers on equipment such as crushers, carbon block rollers, belts, carbon block roller crushers, etc. that need to be filled with lubricating oil.

[0003] In the existing grease filling process, the machine often needs to be stopped for filling, and the grease cannot be filled during operation. In addition, the bearing chamber cannot be filled with grease due to the limited space of the operation position, resulting in inaccurate oil control. If the grease is added while these lubrication points are working, there will be great safety hazards, which may cause some irreversible damage to the equipment or operators. If the grease is not filled, it will also lead to a high frequency of maintenance and a shortened service life of the equipment, which will increase the production cost of the enterprise.

[0004] Since grease is in a semi-solid form and the oil supply pipeline is long, if grease is present in the oil supply pipeline for a long time, it is easy to get clogged, and it will be impossible to fill the lubrication points with grease, which will shorten the service life of the equipment. At the same time, since the oil supply pipe is thin and difficult to clear, replacing the oil supply pipe will also increase the factory's economic expenditure. Utility Model Content

[0008] Further optionally, the oil outlets of the high-temperature oil pipe and the normal-temperature oil pipe are respectively connected to the corresponding bearing chambers, and the oil outlet of the drain pipe is connected to the oil storage tank.

DETAILED DESCRIPTION

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0017] like Figure 1 As shown, a bearing chamber precision oil supply system includes bearing chambers 1 of multiple rotating equipment and an oil storage tank 2 connected thereto by an oil pipe, wherein the oil outlet of the oil storage tank 2 is connected to the inlet of an oil injection pump 3, the outlet of the oil injection pump 3 is connected to a quantitative oil supply barrel 7, and the quantitative oil supply barrel 7 is respectively connected to an air supply pipe 19, a high-temperature oil pipe 21, a normal-temperature oil pipe 20 and a drain pipe 18.

[0018] like Figure 1 As shown, the oil outlets of the high-temperature oil pipe 21 and the normal-temperature oil pipe 20 are respectively connected to the corresponding bearing chamber 1 , and the oil outlet of the drain pipe 18 is connected to the oil storage tank 2 .

[0019] like Figure 1 As shown, the air outlet of the air delivery pipe 19 is connected and fixed to the exhaust port of the air pump 4 and a blocking valve 6 is installed on the air delivery pipe 19 .

[0020] like Figure 1As shown, the second control valve 10 , the electric heater 12 , the first exhaust valve 13 , and the second one-way valve 16 are sequentially installed on the high-temperature oil pipe 21 .

[0021] like Figure 1 As shown, the third control valve 11 , the second drain valve 14 , and the first check valve 15 are sequentially installed on the normal temperature oil pipe 20 .

[0022] like Figure 1 As shown, it also includes an automatic control system, which includes an oil injection pump 3, an air pump 4, a first control valve 5, a blocking valve 6, an oil return valve 9, a second control valve 10, a third control valve 11, and an electric heater 12 electrically connected to a PLC controller 17.

[0023] The implementation principle of a bearing chamber precision oil supply system in the embodiment of the present application is as follows:

[0024] Before filling the grease, the number of times and amount of oiling in one cycle are set by the PLC controller 18, and after the setting is completed, the grease filling is ready;

[0025] When filling grease, the PLC controller 18 will send a signal to start the oil filling pump 3 and open the first control valve 5 at the same time. The oil filling pump 3 will inject the amount of grease filled once from the oil storage tank 2 along the oil filling main pipe 8 into the quantitative oil feeding barrel 7. After the injection is completed, the PLC controller 18 will send a signal to start the air pump 4 to open the blocking valve 6, so that the quantitative oil feeding barrel 7 is filled with pressure, and at the same time open the control valve on the corresponding pipeline. After the control valve is opened, the grease will be injected into the corresponding bearing chamber 1 through the pressure in the quantitative oil feeding barrel 7;

[0026] When the corresponding bearing chamber 1 needs high-temperature grease, the PLC controller 18 will send a signal to start the oil filling pump 3 to inject the grease into the quantitative oil feeding barrel 7. After the grease is injected into the quantitative oil feeding barrel 7, the oil filling pump 3 is stopped to close the first control valve 5, and the air pump 4 is started to open the blocking valve 6 and the second control valve 10, and the electric heater 12 is started. The grease will pass through the electric heater 12 along the high-temperature oil pipe 21. The grease will be heated after passing through the electric heater 12. The heated grease continues to enter the corresponding bearing chamber 1 along the high-temperature oil pipe 21, and the air in the high-temperature oil pipe 21 will be discharged from the first drain valve 13. After the filling is completed, the air pump 4 is stopped, the blocking valve 6 and the second control valve 10 are closed, and the electric heater 12 is stopped at the same time, thereby completing the filling of the high-temperature grease.

[0027] When the corresponding bearing chamber 1 needs normal temperature grease, the grease is injected into the quantitative oil barrel 7 according to the same steps as above, and the air pump 4 is started to open the blocking valve 6 and the third control valve 11, and the grease will be injected into the corresponding bearing chamber 1 along the normal temperature oil pipe 20. After the injection is completed, the PLC controller 17 sends a signal to stop the air pump 4 to close the blocking valve 6 and the third control valve 11, thereby completing the filling of the normal temperature grease.

[0028] Thus, accurate oiling is completed, and the rest of the oiling process is completed according to the above steps. The whole process saves time and effort, and the oiling pipe can be kept in an empty pipe state, which can better prevent the oiling pipe from being blocked, and at the same time ensure the service life of the equipment;

[0029] When there is grease in the quantitative oil barrel 7 and no injection is needed, the air pump 4 is started to open the blocking valve 6 and the oil return valve 9, and the grease will flow into the oil storage tank 2 along the oil return pipe 18;

[0030] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
