　　Main models: Znrh-P1 (10~30L/min), Znrh-P2 (40~125L/min), Znrh-P3 (150~200L/min), Znrh-P4 (220~280L/min), Znrh-P5 (300~400L/min), Znrh-P6 (430~600L/min)

　　Scope of application: used for circulating pressure lubrication of reducers, fans, motors, crushers, bearing bushes

　　ZNRH-P new type intelligent thin oil lubrication station is an upgraded product of JB/ZQ/T4147-1991 XYZ series thin oil station in the heavy machinery industry. The thin oil lubrication station is a device for circulating thin oil lubricating medium. The medium is supplied to the lubrication point of the equipment (the grinding pair with relative motion). After the lubrication point is lubricated and cooled, it returns to the oil tank of the equipment for the next cycle. It is suitable for small and medium-sized reducers in the building materials and metallurgical industries. Bearing circulating pressure provides oil lubrication.

Thin oil lubrication

　　 When the friction surface of the mechanical motion pair is in relative motion, because the surface directly contacts and generates frictional resistance, a part of the energy transferred by the machine is consumed by the friction and the surface heats up, and the parts are worn at the same time.

　　 Thin oil lubrication is to force the lubricating oil to the friction part of the machine to form a lubricating agent film that can withstand part or all of the load on the friction surface, and separate the friction surfaces of the two moving pairs to make the friction between the metal and the metal. It is converted into internal friction between oil film molecules with lower shear strength.

　　 Thin oil lubrication mainly plays the following important roles in the normal operation and maintenance of mechanical equipment: 1) reduce wear, 2) cool down, 3) wash and clean, 4) prevent corrosion, 5) save energy and reduce consumption.

　　 Thin oil lubrication is mainly used for the lubrication of reducers, dynamic and static pressure or sliding shoe bearings of mechanical equipment such as electric power, metallurgy, petrochemical, cement, etc.
