Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The system adopts the induction principle, when the liquid level sensor senses the residual oil quantity in the lubricator oil tank, the detection signal is sent to the control panel, the control panel receives the sensor signal to process, the controller controls the oiling machine to work according to the processing condition of the sensor signal, and the oil is added into the lubricator oil tank through the lubricating system. The system has two modes of pressure relief quantitative oil outlet and pressure quantitative oil outlet. The working principle of pressure relief and quantitative oil discharge is as follows: when the oiling machine works, firstly, the lubricating oil is conveyed into the positive displacement distributor, when the quantitative lubricating oil is fully stored, the oiling machine stops working, meanwhile, the main machine releases pressure, and the spring in the distributor pushes the piston to convey the quantitative lubricating oil to each lubricating part. All equipment and parts in the system can be cleaned and replaced, for example, a filter element in an oil nozzle of the distributor is provided with a filter screen, so that impurities can be further effectively prevented from entering a production machine, and the running of the machine is guaranteed; owing to set up the silica gel valve, impurity blocks up in the front of the filter screen along with the flow of lubricating oil, and the meaning of setting up the silica gel valve lies in guaranteeing that impurity can not flow backwards along with lubricating oil, and this filter core can also take out the impurity of wasing the inside. The pressurized quantitative oil outlet principle of the system is as follows: when the oiling machine works, the pressure oil of the oiling machine pushes the piston in the quantitative distributor to forcibly convey the well-determined lubricating oil in the distributor to each lubricating part in a quantitative manner. The system is matched with DT, DF and DFA type positive displacement distributors, and is suitable for medium and large-sized mechanical equipment with multiple lubricating points and strict and accurate flow requirements.
