Thin oil dispersed lubrication: There are two types of thin oil dispersed lubrication: manual lubrication and fully automatic lubrication. Manual lubrication is generally only used for small parts that are not frequently moved, and it is not easy to connect to the parts provided by centralized lubrication stations, nor is it easy to repair. Parts, such as from points to camshafts and roller bearings. Thin oil dispersed fully automatic lubrication is generally used in industrial equipment, including oil pool lubrication and welding smoke lubrication. The enclosed transmission gear is lubricated with engine oil sump, which is easy to maintain and has a very good lubrication effect. The welding smoke lubrication of the cylinder is a unique structural requirement.

Centralized lubrication of thin oil: In most cases, centralized lubrication of thin oil is lubrication of pressure circulation systems. Generally, lubrication stations (such as car fuel tanks, pumps, valves, etc.) are located around the bottom of the press or in pits, and gear oil pumps are used to lubricate according to the pressure regulating valve. Oil is sent to every lubrication point.

Deep cavity rotor design, larger throughput, iron crushing chamber, built-in lubrication station, thin oil lubrication scheme, can provide a larger speed range, high comprehensive sand production efficiency, and hydraulic opening device for easy maintenance and repair.

The thin oil station adopts two types of control: centralized control and manual control at the machine side, which can be switched by a transfer switch. In centralized control, buttons are used for remote control, and the host is equipped with functions such as stopping grinding, starting the grinding machine, and alarm interlocking signals. Manual control can manually turn on and off the motor of the lubrication station on site.

Adopting an automatic centralized lubrication system instead of the original thin oil lubrication station, large mills do not need to be equipped with expensive high and low pressure thin oil lubrication stations, avoiding thin oil pollution, saving 70% of annual oil costs, while reducing equipment failure rates and maintenance costs for operators, and improving the production efficiency of the entire equipment.

The internal structure of the bar mill sand making machine is mainly composed of a motor, a main reducer, a transmission part, a main bearing, a slow transmission part, a feeding part, a discharging part, an annular seal, a thin oil lubrication station, a large and small gear jet lubrication, a foundation part, etc. The main reducer is a parallel shaft with a hard tooth surface. The joint inspection of the thin oil injection and transportation in the Fengcheng Oilfield operation area by Haji is checking whether the appearance of the non mandatory pressure gauge is intact. This is the content of the innovative and efficient rationalization suggestions collected in this year's labor competition in the operation area.

The damage rate of process pipelines and centrifugal pump inlet and outlet system pressure gauges in the Fengcheng Oilfield operation area is about 3% -4% annually during use, while the damage rate of outlet pressure gauges for screw pumps, gear pumps, and other positive displacement pumps is about 5% -7%. How to reduce instrument damage rate and save calibration costs? In response to this issue, the joint efforts of thin oil injection and transportation and employees such as Haji have proposed. The group strengthened its efforts by starting with details such as checking whether the appearance of the pressure gauge is intact, whether the calibration period is within the validity period, whether the lead seal is intact, and whether the pressure gauge is intact, and so on, gradually achieving benefits.
