[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0026] like Figure 1 As shown, the centralized lubrication system with fault detection of an embodiment of the utility model (hereinafter referred to as the centralized lubrication system) includes a lubrication pump 1, a main line 2, a plurality of mother distributors 3, a plurality of first branches 4, a plurality of sub-distributors 5, a plurality of second branches 6, a plurality of third branches 7 and an indicating device.

[0027] The centralized lubrication system includes an oil tank, etc., the inlet of the lubrication pump 1 is directly connected to the oil tank, and the main line 2 is connected to the outlet of the lubrication pump 1. When in use, the grease in the oil tank can be directly transported to the main line 2 through the lubrication pump 1, and then the grease can be supplied to each subsequent lubrication point through the main line 2.

[0028] The plurality of first branches 4 are connected one by one between the main pipe 2 and the inlets of the plurality of mother distributors 3. Figure 1 As shown, two female distributors 3 may be provided. In this case, two first branches 4 may also be provided. The two female distributors 3 are connected to the main line 2 through the corresponding first branches 4 , respectively.

[0029] Each mother distributor 3 is connected to the inlet of the corresponding sub-distributor 5 through a plurality of second branches 6, and a plurality of third branches 7 are connected one by one between the outlet of the corresponding sub-distributor 5 and the corresponding lubrication point. Figure 1 As shown, there may be four sub-distributors 5, and each mother distributor 3 may correspond to two sub-distributors 5. The number of second branches 6 may be more than the number of sub-distributors 5, wherein a part of the second branches 6 may be connected between the mother distributor 3 and the corresponding sub-distributors 5, and one end of another part of the second branches 6 may be connected to the mother distributor 3, and the other end may directly lead to the corresponding lubrication point.

[0030] like Figure 1 As shown, each sub-distributor 5 may be correspondingly provided with four third branches 7 , and the outlets of the four third branches 7 may directly lead to corresponding lubrication points.

[0031] A first flow meter 8 is provided on each first branch 4, a second flow meter 9 is provided on each second branch 6, and a third flow meter 10 is provided on each third branch 7. The first flow meter 8, the second flow meter 9 and the third flow meter 10 are used to monitor the flow in the corresponding first branch 4, the second branch 6 and the third branch 7 respectively.

[0032] The indicating device is used to alarm and indicate the location where the abnormality occurs when the difference in flow rate changes monitored by the first flow meter 8, the second flow meter 9, and the third flow meter 10 exceeds a set threshold.

[0033] For example, when a sub-distributor 5 has a blockage or other fault, the flow rates of all the third flow meters 10 connected to the sub-distributor 5 will change. For such different changes, the indicator device will generate a corresponding alarm signal. The alarm information generated by different fault locations will be different. With the help of the information fed back by the alarm signal, the staff can quickly find the location of the fault.

[0034] In some embodiments, the indicating device includes multiple indicator lights 13, which respectively correspond to multiple first flow meters 8, multiple second flow meters 9, and multiple third flow meters 10. The indicator lights 13 are used to change when the difference in flow changes monitored by the first flow meter 8, the second flow meter 9, and the third flow meter 10 exceeds a set threshold to indicate the location where the abnormality occurs.

[0035] For example, when a third branch 7 is blocked, the indicator light 13 on the third branch 7 can be turned on. At the same time, since other third branches 7 can supply grease normally, the indicator lights 13 on other third branches 7 will not be turned on. The location of the fault can be quickly determined by the information fed back by the lit indicator lights 13.

[0036] In other cases, when the mother distributor 3 fails, the second flow meter 9 on the second branch 6 and the third flow meter 10 on the third branch 7 behind the mother distributor 3 will detect abnormalities, and the indicator lights 13 corresponding to these flow meters will be lit. Another information fed back by the lighting of the indicator light 13 can be used to determine whether the mother distributor 3 or the first branch 4 is blocked, and then the connection between the first branch 4 and the mother distributor 3 can be cut off to determine whether the first branch 4 is blocked, thereby improving the efficiency of fault judgment.

[0037] In some embodiments, the indicator light 13 may be changed in color, brightness, off, on, or flashing. For example, when a flow meter sends an alarm signal, the color of the indicator light 13 may also change from green to red, thereby also providing an alarm and guidance function.

[0038] In some embodiments, the indicator device includes a panel 11, and a plurality of indicator lights 13 are arranged on the panel 11. Figure 2 As shown, the panel 11 can be a circuit board, and the indicator light 13 can specifically be an LED lamp bead, etc. The indicator lights 13 can all be arranged on the same side of the panel 11, so that the integrated arrangement of the indicating device can be achieved.

[0039] In some embodiments, Figure 2 As shown, the panel 11 is provided with a plurality of areas 12, the number of the areas 12 is the same as the number of the plurality of first flow meters 8, and a plurality of indicator lights 13 are provided in each area 12, and the indicator lights 13 in each area 12 are arranged in a tree shape. This arrangement of the indicator lights 13 is consistent with the arrangement of the parent distributor 3 and the child distributor 5, thereby facilitating the rapid determination of the fault point.

[0040] In some embodiments, the colors of the multiple regions 12 are different. Different colors can be used to quickly distinguish them, thereby further improving the speed of determining the fault point.

[0041] In some embodiments, each first branch 4 is provided with a filter (not shown), and the filter is located upstream of the first flow meter 8. This can reduce the probability of malfunctions such as blockage.

[0042] In some embodiments, each first branch 4 is provided with a valve, and the valve is located upstream of the filter on each first branch 4. The valve can realize the on-off control of the local system corresponding to each mother distributor 3, so as to facilitate the cutting off of the corresponding pipeline during troubleshooting.

[0043] In some embodiments, the valve is a solenoid valve or a ball valve.

[0044] In some embodiments, a control device is included, which can specifically be a PLC control system, etc. Multiple first flow meters 8, multiple second flow meters 9, multiple third flow meters 10, and an indicating device are all electrically connected to the control device, and the control device is used to receive alarm signals emitted by multiple first flow meters 8, multiple second flow meters 9, and multiple third flow meters 10, and control the indicating device to alarm and provide guidance after receiving the alarm signal.

[0045] Each flow meter and control device can be electrically connected wirelessly or wired, and the information detected by each flow meter can be transmitted to the control device. When an alarm signal appears, the control device can control the corresponding indicator light 13 to change, thereby playing an alarm and guidance role.

[0046] Although the above embodiments have been shown and described, it is to be understood that the above embodiments are illustrative and cannot be construed as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments by those of ordinary skill in the art are all within the scope of protection of the present invention.
