Previously, this was done manually. Especially for some large equipment, it was necessary to dismantle the local structure before adding lubricating oil to the transmission components. The operation was cumbersome and inefficient.

[0003] In order to solve the problem of cumbersome operation and low efficiency caused by manual filling of lubricating oil, technicians have proposed an oil filling pump. For example, in the Chinese utility model patent document with the authorization announcement number CN212377735U, an oil filling pump is disclosed, which includes an oil tank, a pump body, a motor and a transmission mechanism, wherein the pump body is arranged at the lower oil outlet of the oil tank, the pump body has a pump oil inlet, a pump oil outlet, and a plunger cavity, the oil inlet and the oil outlet are both connected to the plunger cavity, a plunger is movably inserted in the plunger cavity, the motor is connected to the power input end of the transmission mechanism, and the power output end of the transmission mechanism is connected to the plunger to drive the plunger to absorb oil from the oil inlet and discharge oil to the oil outlet, a battery compartment is arranged on one side of the pump body, and a monitoring control panel is arranged on the other side, the motor action is controlled by the monitoring control panel, thereby driving the plunger action, and the oil filling pump can realize fast single-point oiling of large equipment, and the structural integration is high.

[0004] However, the existing oil filling pumps have the following problems in actual use: (1) In the process of filling lubricating oil for large equipment in the prior art, an overflow device is generally added to the oil supply port of the large equipment to prevent excessive injection of lubricating oil, which causes increased pressure and affects the stability of lubrication operation in the equipment. However, the structure of this external overflow device requires the installation of an additional overflow device on the large equipment during installation, which is inconvenient to assemble. At the same time, the return pipe after overflow is long and cannot be recovered in time. At the same time, this form of external overflow device invisibly increases the overall volume of the equipment and cannot meet the structural compactness requirements of centralized lubrication of large equipment; (2) The oil filling pumps in the prior art do not integrate remote communication technologies such as oil level alarm and overflow alarm, which affects the remote real-time monitoring of single-point oil filling pumps.
