Glossary of Pump Terms: Q
Q: Q is commonly used as a symbol to represent flow rate, which indicates the quantity of fluid passing through a system per unit of time. Flow rate can be expressed in various units, such as volume per unit time.
Quadrant: The term quadrant refers to one-fourth of the circumference of a circle, covering an angle of 90 degrees. It is a geometric concept used to divide a circular shape into equal parts.
Quadratic: Quadratic is an adjective used to describe a polynomial equation where the unknown variable is raised to the power of 2. In such equations, the highest exponent of the variable is 2, and it typically takes the form of ax^2 + bx + c = 0, where a, b, and c are coefficients.
Quality control: Quality control is a business process implemented to ensure and maintain a desired standard of quality in a product or production system. It involves activities such as inspecting, testing, and monitoring to identify and rectify any deviations or defects to meet specific quality requirements.
Quench: Quenching refers to the act of introducing a fluid, often outside the seal, to achieve two objectives: cooling the seal or diluting any product that might be leaking from the seal face. This process helps to regulate temperature and prevent damage or undesirable reactions in the seal.
Quill shaft: A quill shaft is a type of shaft that has a hollow structure, accommodating another shaft inside it. This design allows for transmission of rotational force or torque between the two shafts while providing additional support and stability.
