Marine fuel oil is a kind of fuel with high calorification, good combustion performance, stable storage, small corrosion and wide range of use. It is the most economical and ideal fuel for large horsepower, medium and low speed Marine diesel engines.
Fuel oil is a kind of refined oil, which is the heavy residual product separated from crude oil after steam, coal and diesel oil during petroleum processing.
Viscosity is an important characteristic of liquid fuel. Low viscosity means that liquid is easy to flow, transport and atomize.
The viscosity is high and the liquid takes a long time to set aside.
The viscosity of a fuel is temperature-dependent as well as oil-dependent.
High temperature, low viscosity of oil, easy to flow and atomization, but the oil temperature should not be heated too high, such as when the temperature of heavy oil oil reaches 120 -- 130℃ above, the viscosity will not reduce much, and easy to cause heavy oil gasification, resulting in storage tank roof, fire and other accidents.
SH112H automatic countercurrent kinematic viscometer is designed and manufactured in accordance with the requirements stipulated in the Law of Kinematic viscometers of Dark Petroleum Products of the People's Republic of China standard GB/T11137. It is suitable for the determination of dark petroleum products and fuel oil heavy oil.
Apparatus needed for experiment
1.SH112H automatic countercurrent kinematic viscometer, developed and produced by Shandong Shengtai Instrument Co., LTD.
2. Cannon - Fensk capillary tube and GB17411 bunker fuel oil in accordance with GB/T11137.
Experimental steps:
Preparation work
1. After unpacking the instrument, please count the accessories according to the packing list. If there is any damage, please contact our company.
2. The instrument should be handled vertically. The tilt Angle should not exceed 30 degrees along the height of the instrument.
3. Connect the power supply of the instrument to the socket with a capacity of 220V/10A or above, and pay attention to having a good grounding wire.
