Sliding bearing PV friction tester
Standard
This machine is mainly applicable to GB 7948-1987 plastic bearing limit PV test method, JB/T 7381-2010 powder metallurgy oil bearing PV value determination method and other standards, used for the determination of plastic-based, iron-based, and other substrate powder metallurgy oil bearings and other sliding bearings limit performance.
Working conditions
(1)The tester works normally under the following conditions:
(2)Within the range of room temperature 10℃～35℃.
(3) In an environment where the relative humidity is not greater than 80%.
(4) no vibration around, no corrosive media and no strong electromagnetic interference in the environment;.
(5) The fluctuation range of power supply voltage should not exceed ±10% of the rated voltage, and the fluctuation of frequency should not exceed 2% of the rated frequency; and
(6) Correctly installed on a firm foundation with a levelness of 0.2/1000.
