Description

Greaser with built-in microcontroller and its lubricating oil timing and quantitative injection system

Technical field

The invention relates to the technical field of lubricators, specifically a greaser with a built-in microcontroller and a lubricating oil timing and quantitative injection system thereof.

Background technique

A lubricating device that centrally delivers oil to friction parts is called a lubricator. The lubricator can send a regular and quantitative amount of grease over a long distance under high pressure. The oil delivery starts after the machine is started and continues automatically during the entire working period of the machine. Lubricators are either mechanically driven or manual. A mechanically driven oil pump is driven by an electric motor or a rotating part of the machine itself. In addition to the main transmission, the lubricator is sometimes equipped with an auxiliary device for manual oil pumping to deliver the necessary oil when starting the machine. on friction parts.

Traditional automatic single-point lubricators use a timing device to control the movement of the lubricator oiling device to inject lubricating oil into the lubrication points. At the same time, the LED lights set in the lubricator driving part display alarm signals such as the lubricator's oil volume and the motor battery's power. The above characteristics cannot meet the requirements of the intelligent lubrication system and cannot realize the remote operation, display and alarm of the lubricator's control signals and alarm signals. In addition, some upgraded products use cables to connect the above signals to the controller to achieve data transmission. However, cable transmission requires additional wiring construction, takes up equipment space, extends the construction period, long-term use, and cable aging problems. Reliability risks such as accidental damage are high.

When in use (during work), you need to inject oil into the oil storage chamber 3 before use, uncover the dust-proof activation cap 2 on the top, thereby exposing the grease nozzle 4, install the oil filling joint directly on the grease nozzle 4, and slowly add the lubricating grease Inject it into the greaser until the liquid level reaches the overflow mark, then disconnect the grease fitting 4, wipe the area around the grease fitting 4, and re-cover the dust-proof activation cap 2;

When filling oil for the first time, there may be small bubbles inside the oil storage chamber 3. These air will not affect the function of the greaser, but will enter the lubrication point, causing slow or intermediate grease delivery. Therefore, in order to discharge the air, when filling oil for the first time, add lubricant slowly. Slowly fill to 1mm above the overflow position, and the air will slowly be discharged through the small holes;

Be careful not to replenish the lubricant after it is completely exhausted. This will cause air to enter the lubrication point, resulting in a lack of lubricant at the lubrication point. The air in the pipeline must be evacuated;

The control system controls the electromagnet 17 to be energized. Since the piston block 13 is filled with the magnet block 18, under the action of magnetic attraction, the piston block 13 moves downward along the filling pipe 5, thereby squeezing the grease into the outlet pipe 15. Then it is discharged from the oil outlet 16.
