Crude oil handover trade commonly uses scraper flowmeters.

With the advancement of economic globalization, crude oil—as a commodity—is increasingly integrated into the international trade market. As a critical component in crude oil transit trade, the measurement and handling of crude oil are receiving growing attention. The accuracy of crude oil trade-handover measurements directly impacts the economic efficiency of supply, sales, and transportation. Among the instruments commonly used for measuring and transferring crude oil, the scraper flowmeter stands out. This type of flowmeter employs mechanical measuring elements to continuously divide the flowing liquid into discrete volume segments, thereby accurately determining the total volume of the fluid—a method widely adopted today in petroleum product measurement across China.

What are three-rotor engines, and how do they work?

The three-rotor meter measures fluid flow based on the throttling principle. To maintain a constant differential pressure across the rotor by adjusting the fluid's flow area, it’s also known as a variable-flow-area differential-pressure flowmeter—or simply the three-rotor flowmeter. Now, let’s take a closer look at what exactly a three-rotor is and how it works.

Maintenance and Servicing of the Three-Rotor System

As the weather grows colder and ambient temperatures rise, phenomena like freezing, solidification, and crystal precipitation may occur. Meanwhile, the seismic pressure gauge, operating in excessively low environmental temperatures, has moved beyond its normal working temperature range—directly compromising the accuracy of the three-rotor display. So, let’s now explore how to properly maintain and care for the three-rotor system.

Key points for installing the three-rotor system

The three-rotor flowmeter is an instrument that indicates the measured flow rate and the total volume of fluid passing through over a selected time interval—it’s also an essential tool for accurately measuring the flow of liquids and gases. Proper installation of the three-rotor flowmeter is crucial to its performance. So, let’s now explore the key points for installing a three-rotor flowmeter.

What is the function of a conveyor scraper?

What is the function of a conveyor scraper blade? Polymer conveyor scraper blades are precision-machined from ultra-high molecular weight polyethylene sheets. The scraper itself is also made from ultra-high molecular weight polyethylene. For large scraper conveyors used in coal mining machines, the conveyor blades should be manufactured using a steel-plastic composite material approach. By incorporating ultra-high molecular weight polyethylene as an inner lining, the wear resistance of these large scraper conveyors is significantly enhanced, extending their service life while simultaneously reducing their coefficient of friction. As a result, for large scraper machines, this innovation plays a crucial role in lowering energy consumption and easing the demands placed on the traction and drive systems.
