The object of the present invention is to provide a lubrication distributor monitoring system which has the advantage that multiple distributor bodies can be monitored simultaneously.

The above technical objectives of the present invention are achieved by the following technical solutions:

A lubrication distributor monitoring system includes a monitoring system and a number of distributor bodies. A second piston hole is provided in the distributor body, and a working piston is slidably disposed in the second piston hole. The lubrication distributor body further includes The sensing device for sensing the slip of the working piston and the transmission module connected to the sensing device, the sensing signal of the sensing device is sent to the monitoring system through the transmission module.

By adopting the above technical solution, when the working piston slides up and down in the second piston hole, the induction device senses the movement of the working piston into an induction signal, and a plurality of induction signals are transmitted to the monitoring system through the transmission module, and simultaneously to multiple distributor bodies Monitoring, so that the staff can observe the working condition of the lubricating distributor body without being on site.

Further, the monitoring system includes a data transceiver module, a status analysis module, an alarm module, and a monitoring module,

The data transceiver module is connected to the transmission module to receive the sensing signal of the sensing device;

The normal working data is preset in the state analysis module, the sensing signal is compared with the normal working data, and when there is a deviation between the two, an alarm signal is sent to the alarm module;

The alarm module is used to alarm the user;

The monitoring terminal is coupled to the alarm module and receives an alarm signal from the alarm module.

By adopting the above technical solution, the state analysis module can predict the working condition of the distributor body, and can also analyze whether the distributor body needs maintenance and repair according to the deviation of the sensing signal from the normal working data, to avoid greater problems. The alarm module feeds back the problems of the distributor body to the monitoring terminal in time, reminding the staff to maintain in time.

The flow direction of the lubricating oil in the distributor body is different, and the moving direction of the working piston is also different. By providing magnets at the ends of the working piston and the indicator rod, respectively, when the working piston moves, the adsorption force between the two magnets is used Or the repulsive force drives the indicator rod to move. The proximity switch senses the indicator rod movement signal and transmits it to the receiving device through the transmission module. The worker can observe the working state of the dispenser body on the receiving device. On the other hand, the indicator rod slippage is provided outside the distributor body, instead of directly penetrating the second piston hole to connect with the working piston. In this way, there is no need to open a sliding hole for the indicator rod to slide on the side wall of the distributor body, thereby making The dispenser body has good sealing. When the working piston approaches the indicating rod, the repulsive force between the working piston and the two magnets at the end of the indicating rod gradually increases, and the indicating rod moves with the working piston away from the distributor body; when the working piston moves along the second piston When the hole moves away from the indicator rod, the repulsive force between the working piston and the two magnets at the end of the indicator rod gradually decreases.

Further, a fixing sleeve is threadedly connected in the connecting hole, and the fixing sleeve is hollow. An end screw connected to the end of the fixing piston is screwed in the inner thread, and the adjustment screw is provided with a sliding hole through the axis , The indicator rod is slidingly arranged in the fixed sleeve, and the end away from the working piston is slidingly arranged in the sliding hole, and a first spring is arranged around the indicator rod in the fixed sleeve , One end of the first spring is in contact with the bottom surface of the adjusting screw, the other end is connected to the end of the indicator rod close to the working piston, and the bottom of the fixing sleeve is provided with abutment on the bottom end of the indicator rod Undertake board.

By adopting the above technical solution, the distance between the two magnets located at the end of the working piston and the indicator rod can be reduced, thereby reducing the influence of the thickness of the end wall of the distributor body on the magnetic field energy between the magnets located on both sides of it , So that the indicator rod can move more sensitively with the working piston. The sliding connection between the indicator rod and the distributor body is realized, so that it can be more firmly connected to the outside of the distributor body without affecting its movement with the movement of the working piston.
