It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] In one embodiment, Figure 1 As shown, a dual-line centralized lubrication system is provided, which includes a controller, a lubrication pump 103, a first main line 101, a second main line 102, a distributor 104, an oiler 105 and a pressure detection device 106, the lubrication pump 103 is connected to the inlet ends of the first main line 101 and the second main line 102 respectively, the first main line 101 and the second main line 102 are provided with a distributor 104, the distributor 104 is provided with a pressure detection device 106 and a plurality of oilers 105, the plurality of oilers 105 are connected to a plurality of secondary pipelines 107, the plurality of secondary pipelines 107 are connected to each lubrication point 108 of the mechanical equipment, and are used to inject oil into each lubrication point 108; the controller is connected to the lubrication pump 103 and the pressure detection device 106 respectively;

[0028] The first main pipeline 101 and the second main pipeline 102 constitute a dual-line lubricating oil delivery pipeline, which can work alternately; the lubrication pump 103 can deliver the lubricating oil to the distributor 104 through the first main pipeline 101 or the second main pipeline 102, and the distributor 104 then injects the lubricating oil into each lubrication point 108 through the oiler 105 and the secondary pipeline 107, thereby providing the required lubricating oil for the mechanical equipment to ensure that the equipment maintains a good lubrication state during operation; the pressure detection device 106 can be a pressure switch connected to the oiler 105. In specific implementation, the distributor 104 can use a two-position five-way reversing valve, which can be used to relieve the pressure of the first main pipeline 101 or the second main pipeline 102.

[0029] The controller is used to use the first main line 101 as a working line and the second main line 102 as a non-working line, and send a start-of-work instruction to the lubrication pump 103, so that the lubrication pump 103 builds up pressure in the working line and releases pressure in the non-working line; when the pressure detection device 106 detects that the pressure in the working line rises to a preset first pressure value, the oiler 105 injects oil into each lubrication point 108 of the mechanical equipment; when the pressure detection device 106 detects that the pressure in the working line reaches a preset second pressure value, a stop-of-work instruction is sent to the lubrication pump 103, so that the lubrication pump 103 stops working, so that the dual-line centralized lubrication system enters a pressure-maintaining state, and the distributor 104 releases pressure in the working line so that the lubricating oil enters the oil storage tank of the lubrication pump 103; after a preset time, the second main line 102 is used as a working line, and the first main line 101 is used as a non-working line, and a start-of-work instruction is sent to the lubrication pump 103 again.

[0030] The controller may use the first main line 101 and the second main line 102 as working lines in turn, and control the lubrication pump 103 to work according to the detection result input by the pressure detection device 106, so as to realize automatic and precise control of equipment lubrication.

[0031] Specifically, the controller can first use the first main line 101 as a working line and the second main line 102 as a non-working line, and send a start-of-work instruction to the lubrication pump 103 according to a preset time interval. After receiving the start-of-work instruction, the lubrication pump 103 starts to work, and the dual-line centralized lubrication system enters the oil pumping stage, builds up pressure in the working line, and releases pressure in the non-working line, that is, builds up pressure in the first main line 101 and releases pressure in the second main line 102; in this process, the controller can detect the pressure in the first main line 101 through the pressure detection device 106. When the pressure in the first main line 101 gradually rises to a preset first pressure value, the oiler 105 will inject oil to each lubrication point 108 through the secondary pipeline 107; when the pressure in the first main line 101 reaches a preset second pressure value, the controller sends a stop working instruction to the lubrication pump 103, the lubrication pump 103 stops working, and the dual-line centralized lubrication system enters a pressure maintaining state; after a period of time, the two-position five-way reversing valve serving as the distributor 104 is energized, the pressure in the first main line 101 is released, and the lubricating oil is introduced into the oil storage tank of the lubrication pump 103.

[0032] After a preset time, the second main line 102 is used as a working line and the first main line 101 is used as a non-working line. The controller sends a start-of-work instruction to the lubrication pump 103 again to start the lubrication pump 103, build up pressure in the working line, and release pressure in the non-working line at the same time, that is, build up pressure in the second main line 102 and release pressure in the first main line 101; when the pressure in the second main line 102 gradually rises to a preset first pressure value, the oiler 105 injects oil to each lubrication point 108 through the secondary line 107; when the pressure in the second main line 102 reaches a preset second pressure value, the controller sends a stop-work instruction to the lubrication pump 103, the lubrication pump 103 stops working, and the dual-line centralized lubrication system enters a pressure-maintaining state again; after a period of time, the two-position five-way reversing valve serving as the distributor 104 loses power, the pressure in the second main line 102 is released, and the lubricating oil is again introduced into the oil storage tank of the lubrication pump 103.

[0033] After another preset time, the controller will repeat the above process and continue to issue commands to maintain the lubrication cycle.

[0034] The controller of the above-mentioned dual-line centralized lubrication system can realize precise control and status monitoring of the lubrication pump 103, monitor the internal pressure of the working pipeline in real time through the pressure detection device 106, and control the lubrication pump 103 to stop working when the pressure is too high, thereby protecting the pipeline and ensuring that the system operates within a safe pressure range.

[0038] The controller is also used to detect the oil level value in the oil storage tank through the oil level sensor, and when the oil level value is lower than the preset safe oil level value, control the motor to stop working and control the alarm light to alarm.

[0039] In the above embodiment, the controller can monitor the oil level through the oil level sensor to ensure that the oil is sufficient, and when the oil level is too low, the motor is controlled to stop to ensure working safety.

[0040] In one embodiment, the controller is also used to detect the operating voltage and operating current of the motor, and control the motor to stop working when the operating voltage exceeds the safe operating voltage range or the operating current exceeds the safe operating current range, thereby preventing the motor from operating at low voltage and preventing the motor from overcurrent; and, detect the solenoid valve operating current of the two-way valve, and control the motor to stop working when the solenoid valve operating current exceeds the safe operating current range, thereby preventing the two-way valve from overcurrent.
