Automatic viscosity measurement solution for heavy oil
Viscosity is an important characteristic of liquid fuel. Small viscosity means that the liquid is easy to flow, easy to transport and atomize, which is beneficial to the operation of boiler.
Viscosity, liquid set aside for a long time.
The viscosity of heavy oil is dependent on temperature as well as on the quality of the oil.
High temperature, oil viscosity is small, easy to flow and atomization, but the oil temperature can not be heated too high, such as when the temperature of heavy oil reaches more than 120-130 ℃, viscosity reduction is not much, and easy to cause the gasification of heavy oil, leading to storage tank roof, fire and other accidents.
SH112H automatic countercurrent kinematic viscometer is designed and manufactured in accordance with the requirements of the standard GB/T11137 "kinematic viscometer for dark petroleum products" of the People's Republic of China. It is suitable for the determination of dark petroleum products and heavy oil.
Instruments for the experiment
1.SH112H automatic countercurrent kinematic viscometer was developed and produced by Shandong Shengtai Instrument Co., Ltd.
2. Cannon - Fenske capillary conforming to GB/T11137.
Experimental steps:
First, preparation work
1. After the instrument is unpacked, please count the accessories according to the packing list. If there is any damage, please contact our company.
2. The instrument should be carried vertically, and the tilt Angle along the height of the instrument should not exceed 30 degrees. It should be placed in a dark place and placed smoothly, otherwise there will be vibration after the start of the instrument, which will affect the service life of the instrument.
3, the instrument power supply is connected to the capacity of more than 220V/10A socket, pay attention to must have a good grounding wire.
Second, the experimental process
The functions of the instrument are described as follows according to different interfaces:
1. Switch on the machine and display the name of the instrument. After 2 seconds, it will automatically enter the test interface.
2. Test interface:
As shown in the figure above, there are two buttons on the top of the interface: "Main Interface", "Parameter Settings", "System Settings" and "Historical Data".
When the temperature of the constant temperature bath is equal to the set temperature, click "Start" constant temperature time to start the timing. When the set constant temperature time is reached, the timing will stop automatically. The buzzer will alarm for 3 seconds, and the display screen will display "Constant temperature time is over, start the test".
Press the "Stop" button to terminate the test without saving the test results.
