Product Application
The MOEORW-WEL93 is extensively deployed in laboratories across oil extraction fields, refineries, commodity inspection bureaus, power generation enterprises, marine shipping companies, and research universities. It is primarily utilized to measure the kinematic viscosity of Newtonian liquids and determine the laboratory density of crude oil and liquid petroleum products.
Laboratory Safety & Preventive Operational Measures
Anti-Dry-Heating Protection: The water bath must be filled with a sufficient volume of liquid medium (the liquid level should maintain a distance of 10 to 20 mm from the lower surface of the top cover) before turning on the power. Activating the heater without fluid is strictly prohibited, as it creates an immediate fire hazard and will destroy the heating elements.
No Unauthorized Dismantling: This instrument utilizes microcomputer-based intelligent control and requires no internal daily maintenance. If a fault occurs, external operators are strictly forbidden from opening the housing; please contact the factory service line directly.
Environmental Compatibility: The tester must not be installed in rooms containing corrosive gases, as these will corrode the circuitry and severely shorten the instrument's lifespan. Avoid spaces with temperatures below 5°C or above 40°C, high humidity, or direct sunlight.
Grounding Inspection: For personal safety, the three-core power cord must be reliably grounded. The grounding continuity between the power plug and the metallic components of the water bath cover should be verified every three months.
FAQ
Q1: How do you ensure the absolute vertical alignment of capillary viscometers during a test?
A: The MOEORW-WEL93 comes equipped with specialized anodized aluminum viscometer clamps. Operators simply press the circular button on the clamp to insert and secure the viscometer tube. By adjusting the 3 hand-tightened screws on the fixture, the viscometer can be calibrated swiftly to a perfectly vertical position, eliminating flow rate errors caused by tilting.
Q2: What is the standard operational procedure for conducting a petroleum density test on this instrument?
A:
1.Activate the temperature control system (and engage the immersion cooler if low temperatures are required) until the water bath stabilizes.
2.Transfer the sample into a clean density cylinder and use a piece of clean filter paper to remove any air bubbles forming on the surface.
3.Place the density cylinder into the water bath and allow it to sit for a constant temperature duration of 30 minutes.
4.Insert the appropriate hydrometer, release it once it reaches its equilibrium position, and record the reading with an accuracy of 0.0001 g/cm³.
Q3: Which constant temperature bath liquids should be utilized for different testing temperatures?
A: To avoid hardware damage caused by dry heating and to guarantee precise temperature control, appropriate thermal liquids must be added to the bath based strictly on the required testing temperature:
50°C to 100°C: Transparent mineral oil, glycerin, or methyl silicone oil (viscosity <100cs).
20°C to 50°C: Pure water.
0°C to 20°C: A mixture of water and ice, or a mixture of ethanol and dry ice.
