Detailed Description

Suitable for: Oil-impregnated bearings field, self-lubricating sintered metal structural parts New Materials Research. Principle: In accordance with ASTM B328; MPIF Standard45; JIS Z2506; GB/T 5163 standard, adopt the buoyancy method of Archimedean principle, can measure the density accurately and fast. Technical data: A, Measuring for oil-content of oil-impregnated bearings and other self-lubricating sintered metal structural parts is the standard test method in MPIF. B, Proper lubrication conditions require sufficient interconnected porosity and satisfactory oil impregnation of the porosity. This can bring heat via the running of the products, and increase the duration of distributing heat and lubricating by using lube. Therefore we know the importance of oil content by volume for Oil-impregnated bearings. MPIF B328：Impregnate Methods for the test specimens. 1、 At room temperature, using a suitable evacuating method, reduce the pressure over the immersed specimen to not more than 7 kpa pressure for 30 min. Then permit the pressure to increase to atmospheric pressure and the specimen to remain immersed in oil 20 to 65 cst 38℃ at room temperature and pressure for 10 min. 2、 Immerse the specimen in oil, viscosity of 20 to 65 cst at 38℃,hold at a temperature of 82℃± 5℃ for at least 4 h and then cool to room temperature by immersion in oil at room temperature. Functions and specification: MH-204S: Model MH–204S Measurable range 0.0001g 〜 200g Weight resolution 0.0001g Density resolution 0.0001 g/cm3 Functions By linking with computer can directly show the green density, sintered density, porosity and oil content by volume Standard interface RS-232 Remarks Standard equipment：calculating software CD Self-provided：XP Computer MH-123U：  Formula 1:MH-123U can directly show the bulk density, apparent porosity, volume and wet density of powder metallurgy samples  Formula 2：MH-123U can directly measure the oil content by volume Model MH-123U Measurable range 0.001- 120g Weight resolution 0.001g Density resolution 0.001 g/cm3 Functions can directly show the bulk density, apparent porosity, volume, wet density and oil content by volume Standard interface RS-232 Optional equipments A．Automatic vacuum siphon machine MHV-2 B：Electromagnetic heating equipment
