The lubricating device 1 is respectively connected with the oil distributing pipeline 2 and the oil pressure sensor 4 through a cutting sleeve type three-way joint 3, and the oil pressure sensor 4 is used for detecting blockage and feeding back an alarm signal to the control device. Oil pressure sensor 4 real-time detection system running state at main oil circuit installation oil pressure sensor 4, reaches the set pressure when lubricating system's pressure, and oil pressure sensor 4 acts and feeds back the signal to lubricating pump body PLC control, sets up alarm signal.
The oil pressure sensor 4 has the main technical parameters: the action pressure: 100-200 bar; the type of the adjustable contact: normally open/normally closed (passive).
The control device adopts a PLC controller and is used for setting and controlling the lubricating period, the lubricating time, the lubricating amount and the flow rate to alarm. The electric system and the centralized lubrication system are provided with monitors, 1 leakage protector is connected in parallel from the cabin control cabinet and is connected to the AC230V branch power supply lubrication branch power supply idle opening belt leakage protection function, a lubrication period is set on the electric control board, a PLC (programmable logic controller) with a pump body controls a lubrication mode, and the period can be adjusted according to the collection condition of an actual lubrication filling machine after the electric system runs for a period of time.
The installation mode is as follows:
installing a lubricating pump: the lubricating pump is arranged on a corresponding fixed support of the fan through an adapter plate, 4 phi 10 holes need to be drilled in the support on site, and the specific position can be selected on site. Live installations are strictly prohibited. The liquid level line on the oil tank is clear and clean during installation. The lubrication pump station is required to be firmly installed and fixed at a position which has less environmental pollution, convenient oil filling and maintenance and easy observation and operation. The installation surface should be level, and the installation connection should be reliable.
Installing a lubricating oil pipe: and selecting a proper pipeline according to the installation positions of the lubricating pump and the distributor, and fixing the oil pipe. The oil pipe should be cut off vertically in the axial direction, so that the pipe orifice cannot be cracked or scratched, and the oil pipe cannot be flattened. When the pipeline is installed, the pipeline must be kept clean and clean without pollutants. The pipeline must be short and quick to reduce the pressure loss of the system and ensure the smooth pipeline.
