Summary of Check Valve Standards (2)
The Gate, Globe and Check Valves Standards
Gate valves are primarily used to start or stop a flow in a pipe. They are often used in steam and water systems, where the flow can be intermittent or constant. Gate valves are most often used for regulate and regulate the flow of water, steam, or other......

Torque on the main motor shaft
Torque from the Main Axis of Motor
The torque from the main axis of a motor is a measure of how much power the motor is able to produce to drive machinery or other equipment. The torque, or moment of force, is also sometimes referred to as ‘twist’, and is measured in Nm (Newton metres).
The to......
How to adjust the roll position
The Adjustment of Position of Rolling Mills
Rolling mills are heavy machines used in industries for processing metal and other materials by passing them through a series of rolls. They are extensively used in the metalworking industry and come in various forms and sizes, each with different featu......
Shaft material and blank
Prewired axles are an integral part of automobile manufacturing and help avoid costly downtime. They are manufactured from raw materials such as iron, steel, aluminum and brass and are pre-assembled in factories before finishing. Even though pre-wired axles are relatively simple in their design, h......
Idle torque and dynamic torque
Torque and torque in rotary motion are two important physical quantities that are expressed in the same magnitude and unit. However, they have different meanings and physical meanings.
Torque is the moment of force on a rotating angular object, expressed in newtons per meter. It is a vector quan......
The second law of thermodynamics second law of thermodynamics
The Second Law of Thermodynamics The Second Law of Thermodynamics states that the total entropy of an isolated system always increases over time. Entropy is a measure of the amount of energy available to do work in a system. Increasing entropy represents a loss of usable energy in the system. The S......
