Tgd engine oil testing, lubricant anti-emulsification tests, oil mechanical impurities tests
China is testing the quality evaluation and failure diagnosis of more than 100 oil items, including lubricant, lubricant, grease, special oil, diesel, transformer oil, in accordance with national standards (gb), iso, astm, and product quality standards. Test reports are mutually recognized by more than 70 countries, and oil quality assessments are credible and can serve as a basis for legal arbitration。
Turbo oil, also known as flat oil or steamer oil, is used mainly for steam turbines in power plants, water tanker generators at hydropower stations and other lubricating events requiring deep lubricants。

Viscosity is determined by three methods: power viscosity, motion viscosity and condition viscosity。
(1) power viscosity: nit is the resistance of the two liquid layers at a distance of 1 cm, each having a relative movement rate of 1 cm/s, in g/rimi-s. 1 g/cm/s = 1 pg: industrially active viscosity units are expressed in berths。
(2) motion viscosity: at temperature t°c, motion viscosity is expressed in sign gamma, in units it is in s, i. E. Square metres per second (m2/s), which is commonly used in physical measurements, and in cst it is in sq. Mm per second (i. E. 1 cst = 1 mm2/s). Motion viscosity is widely used to determine the viscosity of liquid petroleum products such as jet fuel oil, diesel oil, lubricant, post-use lubricant oil, crude oil, etc., which is determined in reverse current method
(3) conditional viscosity: for each country the following three types of condition viscosity are commonly used:
1 ng viscosity is also called engler viscosity. (b) is the ratio of the time (s) required to eject 200 ml samples from a viscosity meter at specified temperatures (e. G. 50 °c, 80 °c, 100 °c) to the time (s) required for distilled water to eject the same volume at 20 °c。

Testing techniques
The method used to test a certain fluid performance indicator and to test its physicochemical performance to determine its eligibility. Examples include viscosity, moisture, acid values, antioxidation, etc。
Detection products: quality assessment of products such as oil, oil for electricity, lubricant, cutting fluid, anti-freeze for vehicles, washing agents, solid fuels, etc。
Criteria
In accordance with national standards (gb), standards (iso), american material test association standards (astm), electrotechnical commission standards (iec), petrochemical industry standards (sh) and standards for electrical industry (dl) and product quality standards。
Problem resolution
The quality system meets the technical requirements of iso/iec 17025 and has an objective and impartial laboratory system。
New oil quality ratings can help enterprises complete product acceptances, provide direction to improve product quality, avoid procurement risks, control the quality of new reservoirs and ensure the use of oil。
