[0028] In some embodiments, Figure 1 As shown, in an embodiment of the present application, a control method for a dry oil lubrication system is provided, comprising:

[0029] Step S101, when the dry oil lubrication system is in automatic mode, the solenoid valve is opened according to a preset cycle by a controller to connect the main oil pipe with the refueling point;

[0030] Step S102, when the dry oil lubrication system is switched from the automatic mode to the manual mode, a control instruction of the user is received through the controller, and the solenoid valve is opened in response to the control instruction;

[0031] Step S103, when the solenoid valve fails to work, the manual valve is opened to connect the main oil pipe with the refueling point.

[0032] In this embodiment, a control method for a dry oil lubrication system is proposed. The dry oil lubrication system includes components such as a controller, a solenoid valve, a hand valve, a main oil pipe, and a refueling point.

[0033] It should be noted that the controller is used to control the solenoid valve, which is arranged between the main oil pipe and the refueling point. The manual valve is connected in parallel with the solenoid valve and is also arranged between the main oil pipe and the refueling point.

[0034] Exemplarily, the dry oil lubrication system may be a manual and automatic integrated dry oil centralized lubrication system.

[0035] Exemplarily, the controller may be a PLC (Programmable Logic Controller) control box.

[0036] Exemplarily, the refueling point may be a lubrication point connected to a lubricating oil inlet of the equipment to be refueled.

[0037] Exemplarily, the dry oil lubrication system may have two modes: an automatic mode and a manual mode.

[0038] When the dry oil lubrication system is in automatic mode, the controller opens the solenoid valve according to a preset cycle to connect the main oil pipe and the refueling point, wherein the preset cycle is a preset control cycle.

[0039] Exemplarily, the preset period may be 1 hour.

[0040] Exemplarily, the dry oil lubrication system may include a plurality of solenoid valves, and the plurality of solenoid valves may be opened in sequence by a controller.

[0041] When the dry oil lubrication system is switched from the automatic mode to the manual mode, the controller receives a control instruction from the user and responds to the control instruction to open the solenoid valve, wherein the control instruction is an instruction to control the solenoid valve.

[0042] Exemplarily, the dry oil lubrication system may include a plurality of solenoid valves, and the control instruction may be an instruction to open a target solenoid valve among the plurality of solenoid valves.

[0043] When the solenoid valve fails to work, it means that the controller cannot control the solenoid valve. By opening the manual valve, the main oil pipe and the refueling point are connected.

[0044] Exemplarily, the user manually opens the hand valve to connect the main oil pipe with the refueling point, and after refueling is completed, the hand valve can be manually closed.

[0045] It should be noted that adding a hand valve inside the dry oil lubrication system ensures that the dry oil lubrication system can be refueled normally when the solenoid valve fails to work, thereby improving the operating stability of the dry oil lubrication system.

[0046] The control method of the dry oil lubrication system in this embodiment opens the solenoid valve according to a preset cycle through the controller, thereby improving the refueling efficiency of the dry oil lubrication system. In addition, by setting a manual valve in parallel with the solenoid valve, the operating stability of the dry oil lubrication system is improved.

[0047] In some embodiments, an embodiment of the present application provides a control method for a dry oil lubrication system, further comprising:

[0048] Step S201, receiving a control instruction input by a user through a host computer;

[0049] Step S202: transmitting the control instruction to the controller via the host computer.

[0050] In this embodiment, the dry oil lubrication system further includes a host computer, wherein the host computer is communicatively connected with the controller.

[0051] The host computer receives the control instructions input by the user and transmits the control instructions to the controller.

[0052] Exemplarily, the host computer includes a touch screen, and the user inputs control instructions through the touch screen.

[0053] For example, when a command is issued from the upper screen, the dry oil pump starts working first to provide pressurized dry oil to the system.

[0054] For example, the touch screen can display the working status of each component in the dry oil lubrication system.

[0055] For example, the PLC is networked with the upper screen via Ethernet, and can view the oil filling situation in real time. At the same time, it can record the alarm logs such as oil filling failure in the upper computer to facilitate the search for fault points.

[0056] In some embodiments, an embodiment of the present application provides a control method for a dry oil lubrication system, further comprising:

[0057] Step S301, detecting the flow rate of the refueling point through a flow sensor to obtain the point flow rate;

[0058] Step S302, when the point flow is greater than the flow threshold, it is determined that refueling at the refueling point is completed.

[0059] In this embodiment, the dry oil lubrication system further includes a flow sensor, wherein the flow sensor is connected to the refueling point.

[0060] The flow rate at the refueling point is detected by a flow sensor to obtain the point flow rate. When the point flow rate is greater than the flow threshold, it means that the flow rate at the refueling point has changed, and it can be determined that refueling at the refueling point has been completed.

[0061] For example, when the flow sensor on the pipeline detects a flow change, the dry oil lubrication system can consider that the oiling at this point is effective, otherwise an alarm will be issued on the screen of the host computer.

[0062] In some embodiments, an embodiment of the present application provides a control method for a dry oil lubrication system, further comprising:

[0063] Step S401, detecting the pressure of the main oil pipe through a pressure sensor to obtain a pressure value;

[0064] Step S402, when the pressure value is less than the pressure threshold, a normal pressure signal is sent to the controller through the pressure sensor;

[0065] Step S403: When the pressure value is greater than the pressure threshold, the controller controls the oil pump to stop working.

[0066] In this embodiment, the dry oil lubrication system further includes a pressure sensor and an oil pump, wherein the oil pump is connected to the main oil pipe and the pressure sensor is arranged on the main oil pipe.

[0067] The pressure of the main oil pipe is detected by a pressure sensor to obtain a pressure value, wherein the pressure value is used to indicate the pressure state of the main oil pipe.

[0068] When the pressure value is less than the pressure threshold, it indicates that the pressure of the main oil pipe is normal, and a normal pressure signal is sent to the controller through the pressure sensor.

[0069] When the pressure value is greater than the pressure threshold, it indicates that the pressure of the main oil pipe is abnormal, and the oil pump is controlled to stop working through the controller.

[0070] For example, after the dry oil lubrication system is powered on, it automatically detects whether the system pressure is normal. When the pressure is lower than the set value, it feeds back a normal pressure signal to the PLC controller to prevent the pressure sensor from failing. When the system pressure is higher than the set pressure, the dry oil pump stops working and the host computer alarms.

[0071] For example, the electrical control adopts the control technology with PLC and host computer as the core, and uses flow sensor and pressure sensor for detection. Each channel can realize 2 on-off control modes and 3 control methods.

[0072] In some embodiments, an embodiment of the present application provides a control method for a dry oil lubrication system, further comprising:

[0073] Step S501, when the dry oil lubrication system is in manual mode, a control instruction is sent to a controller via a wireless remote controller to open the solenoid valve.

[0074] In this embodiment, the dry oil lubrication system further includes a wireless remote controller. When the dry oil lubrication system is in manual mode, a control instruction is sent to the controller via the wireless remote controller to open the solenoid valve.

[0075] For example, in manual mode, a remote controller can issue a command to cause a wireless relay connected in parallel with the relay in the control box to issue a command to turn on the corresponding solenoid valve on site.

[0076] In some embodiments, an embodiment of the present application provides a control method for a dry oil lubrication system, further comprising:

[0077] Step S601: When a dry oil lubrication system fails, an alarm signal is output through a controller.

[0078] In this embodiment, in the event of a failure in the dry oil lubrication system, an alarm signal is output to the user through the controller, wherein the alarm signal is a signal to warn of the failure.

[0079] For example, when any component such as the solenoid valve, the hand valve, the main oil pipe and the refueling point fails, an alarm signal is output to the upper computer through the controller.

[0080] For example, Figure 2 As shown, in an embodiment of the present application, a control method for a dry oil lubrication system is provided, comprising:

[0081] S1, start the lubrication pump;

[0082] S2, whether the pressure is lower than the set value, if so, end, if not, execute S3;

[0083] S3, whether it is automatic mode, if yes, execute S4, if no, execute S14;

[0084] S4, automatic operation mode;

[0085] S5: Check whether the lubrication point is engaged. If so, it is over. If not, execute S6.

[0086] S6, after PLC logic judgment, outputs oiling signal;

[0087] S7, the corresponding relay coil is energized;

[0088] S8, turn on the solenoid valve for n seconds;

[0089] S9, turn off the solenoid valve for n seconds;

[0090] S10, whether the sensor detects flow feedback, if not, execute S11, if yes, execute S12;

[0091] S11, the upper computer screen alarm;

[0092] S12, whether the lubrication times are reached, if yes, execute S13, if not, execute S8;

[0093] S13, try to lubricate the next point;

[0094] S14, manual operation mode;

[0095] S15, whether to use the remote control, if yes, execute S16, if not, execute S20;

[0096] S16, press the corresponding point button;

[0097] S17, the corresponding relay coil is energized;

[0098] S18, turn on the solenoid valve;

[0099] S19, whether the corresponding point button is lifted, if so, it is finished, if not, execute S18;

[0100] S20, open the bypass valve;

[0101] S21, lubrication corresponding points.

[0102] In this embodiment, when a command is issued from the upper screen, the dry oil pump starts working first to provide pressurized dry oil to the system.

[0103] In automatic mode, the PLC sends an opening command to the electromagnetic valve on site through the relay, so that the corresponding refueling point is connected to the main pipeline. When the flow sensor on the pipeline detects a flow change, the control system considers that the refueling at this point is effective, otherwise an alarm will be issued on the upper screen.

[0104] When the automatic mode fails, the manual mode can be used to manually open the hand valve in parallel with the pump and the solenoid valve 9 to refuel.

[0105] In manual mode, commands can also be issued through the remote control, so that the wireless relay connected in parallel with the relay in the control box issues commands to turn on the corresponding solenoid valve on site.

[0106] For example, the control hardware system is as follows: Figure 3 As shown, the PLC is networked with the host screen through Ethernet, and can view the oil filling situation in real time. At the same time, the alarm logs such as oil filling failure are recorded in the host computer to facilitate the search for fault points.

[0107] The electronic control adopts the control technology with PLC and host computer as the core, and uses flow sensor and pressure sensor for detection. Each channel can realize 2 on-off control modes and 3 control methods.

[0108] The working process of the pressure sensor: after the system is powered on, it automatically detects whether the system pressure is normal. When the pressure is lower than the set value, it feeds back a normal pressure signal to the PLC controller to prevent the pressure sensor from failing. When the system pressure is higher than the set pressure, the dry oil pump stops working and the host computer alarms.

[0109] The flow sensor working process, after the system is powered on, automatically detects whether the corresponding pipeline flow is normal. If the flow is detected before the pump station starts, the host computer will alarm. During normal refueling, the corresponding branch pipe solenoid valve automatically opens and the main pipe pressure is normal. If no flow is detected, the host computer will alarm.

[0110] In some embodiments, Figure 4 As shown, in an embodiment of the present application, a control device 700 of a dry oil lubrication system is provided, comprising:

[0111] The control unit 702 is used to open the solenoid valve according to a preset period through the controller when the dry oil lubrication system is in automatic mode, so as to connect the main oil pipe with the refueling point;

[0112] The control unit 702 is also used to receive a control instruction from a user through a controller when the dry oil lubrication system is switched from an automatic mode to a manual mode, and respond to the control instruction to open the solenoid valve;

[0113] The control unit 702 is also used to connect the main oil pipe and the refueling point by opening the manual valve when the solenoid valve fails to work.

[0114] In this embodiment, a control device 700 of a dry oil lubrication system is proposed. The dry oil lubrication system includes components such as a controller, a solenoid valve, a manual valve, a main oil pipe, and a refueling point.

[0115] It should be noted that the controller is used to control the solenoid valve, which is arranged between the main oil pipe and the refueling point. The manual valve is connected in parallel with the solenoid valve and is also arranged between the main oil pipe and the refueling point.

[0116] Exemplarily, the dry oil lubrication system may be a manual and automatic integrated dry oil centralized lubrication system.

[0117] Exemplarily, the controller may be a PLC (Programmable Logic Controller) control box.

[0118] Exemplarily, the refueling point may be a lubrication point connected to a lubricating oil inlet of the equipment to be refueled.

[0119] Exemplarily, the dry oil lubrication system may have two modes: an automatic mode and a manual mode.

[0120] When the dry oil lubrication system is in automatic mode, the controller opens the solenoid valve according to a preset cycle to connect the main oil pipe and the refueling point, wherein the preset cycle is a preset control cycle.

[0121] Exemplarily, the preset period may be 1 hour.

[0122] Exemplarily, the dry oil lubrication system may include a plurality of solenoid valves, and the plurality of solenoid valves may be opened in sequence by a controller.

[0123] When the dry oil lubrication system is switched from the automatic mode to the manual mode, the controller receives a control instruction from the user and responds to the control instruction to open the solenoid valve, wherein the control instruction is an instruction to control the solenoid valve.

[0124] Exemplarily, the dry oil lubrication system may include a plurality of solenoid valves, and the control instruction may be an instruction to open a target solenoid valve among the plurality of solenoid valves.

[0125] When the solenoid valve fails to work, it means that the controller cannot control the solenoid valve. By opening the manual valve, the main oil pipe and the refueling point are connected.

[0126] Exemplarily, the user manually opens the hand valve to connect the main oil pipe with the refueling point, and after refueling is completed, the hand valve can be manually closed.

[0127] It should be noted that adding a hand valve inside the dry oil lubrication system ensures that the dry oil lubrication system can be refueled normally when the solenoid valve fails to work, thereby improving the operating stability of the dry oil lubrication system.

[0128] The control device 700 of the dry oil lubrication system in this embodiment opens the solenoid valve according to a preset cycle through the controller, thereby improving the refueling efficiency of the dry oil lubrication system. In addition, by setting a manual valve in parallel with the solenoid valve, the operating stability of the dry oil lubrication system is improved.
