At the same time, the vertical part of the "Z"-type pipeline can be fully filled with oil. When the pneumatic piston oil pumping valve 2 is actuated, the pressure difference of the vertical oil pipe can effectively achieve the effect of uniformly dripping the lubricating oil. The contactless oil dripping lubrication chain 4 can be cleaner and can ensure that no foreign matter is left.

[0031] For details, see Figure 1An output pipe 8 is installed at the lower end of the oil tank 1, and the output pipe 8 is installed with the pneumatic piston oil pumping valve 2.

[0032] For details, see Figure 1 and Figure 2 The electric control part 6 includes a timer 601, a solenoid valve 5, a trigger for automatic lubrication valve body action 602 and a parallel manual button 603, and the timer 601, the solenoid valve 5, the trigger for automatic lubrication valve body action 602 and the parallel manual button 603 of the electric control part 6 are electrically connected. The timer 601, the solenoid valve 5, the trigger for automatic lubrication valve body action 602 and the parallel manual button 603 form the electric control part 6, so as to facilitate the intelligent control of the solenoid valve 5. The timer 601 is turned on when the equipment works for 1000 hours, and the solenoid valve 5 is triggered once every 0.5 seconds. Through the timer 601, when the equipment works for 1000 hours, lubrication can be performed for 30 minutes, and the solenoid valve 5 can be activated once every 0.5 seconds.

[0033] Working principle: When in use, the solenoid valve 5 is controlled by the PLC program, and the piston-type pneumatic oil pumping valve is used to reciprocate to pump the lubricating oil in the oil tank 1 into the oil separator 3, and then the oil is divided into the second connecting pipes 10 on both sides through the oil separator 3. The method of not sealing the straight rod and sealing the side drilling holes at the end of the straight rod has been used, but due to the slight height difference between the oil pipes on both sides, it will affect the uniformity of lubrication; after many verifications, the second connecting pipes 10 on both sides of the outlet of the oil separator 3 finally adopt a "Z" type structure, and the oil outlet is flattened to control the flow rate. At the same time, the vertical part of the "Z" type pipeline can be fully filled with oil. When the piston oil pumping valve is activated, The pressure difference of the vertical oil pipe can effectively achieve the effect of uniform dripping of lubricating oil. The equipment running time is recorded by timer 601. Lubrication is automatically started for 30 minutes every 1000 hours of operation as required. At the same time, a manual start button is set on the equipment operation screen. In the program, there are two operating channels in parallel with automatic lubrication, which are used for manual operation of debugging or replenishing lubrication. The program triggers the solenoid valve 5 to act once every 0.5 seconds, and then the pneumatic piston oil pumping valve 2 will act once. The oil output can be adjusted according to the actual situation, and finally the final oil output of the second connecting pipeline 10 reaches the optimal state, that is, there is no excess grease dripping and lubrication is sufficient.
