1. Product Overview
XYZ thin oil station is the heart of the thin oil circulating lubrication system, providing constant pressure lubricating oil for the friction parts of the machine. Suitable for lubricating medium kinematic viscosity at 40 ℃ for 22~460mm²/min in the thin oil circulating lubrication system. Products are mainly used in petroleum, chemical, power plants, metallurgy, mining and other industries.

The products are mainly composed of screw pump, motor, cooler, filter, safety valve, overflow valve, self-regulating valve, instrument, electrical appliance, oil tank, base and various pipelines, pipe fittings, valves, etc.

The oil supply pressure of the thin oil station is ≤ 0.5MPa, and the oil supply temperature is 40±5 ℃; the filtration accuracy is 0.01~0.13mm; the cooling water inlet temperature is ≤ 33 ℃, and the cooling water pressure is ≤ 0.4MPa; the oil inlet temperature of the heat exchanger is ≤ 50 ℃; the oil temperature drop is ≥ 8 ℃; the steam pressure is 0.3MPa when the steam is used to heat the oil.

2. working principle
First, start the oil pump of the thin oil station. The lubricating oil is sucked out of the oil tank by the screw pump, and is directly sent to the lubrication point of the equipment through the check valve, cooler, and double-cylinder oil filter. When the system pressure reaches the allowable working pressure Start the host equipment operation. In normal operation, one oil pump is working and one is standby. For some reason, the system pressure drops. When it drops to the set value, the pressure controller controls the standby pump to automatically open, and the dual pumps work together until the pressure is normal, the standby pump automatically stops; if the oil pressure continues to drop to another setting When the value is set, a fault alarm will be issued through another pressure controller.

The nominal pressure of the thin oil lubrication system is 0.4 Mpa, so the thin oil station has set the discharge pressure of the self-regulating valve in the system at 0.4 Mpa before leaving the factory. when the pressure of the thin oil lubrication system exceeds the set pressure, the self-regulating valve will automatically open to relieve the pressure, and the excess oil will flow back to the oil tank.

The oil station is equipped with a double-cylinder oil filter, of which one set of filter elements works and the other set of filter elements is for standby. There are a differential pressure gauge and a differential pressure transmitter between the inlet and outlet of the oil filter. When the differential pressure exceeds 0.05MPa, an alarm will be sent, the standby filter element will be manually switched to work, the original working filter element will be taken out, and the filter screen will be cleaned or replaced.

3. product features
1) A standby oil pump is provided to ensure continuous oil supply to the lubrication point.
2) The double-cylinder oil filter is adopted, and the filter element can be cleaned and replaced without stopping.
3) The tubular oil cooler is adopted, which has good cooling effect, low resistance and easy maintenance.
4) Equipped with instrument panel and transmitter, it is convenient to observe operating parameters and can realize remote automatic control.
