The Working Principle of Centrifugal Pump Mechanical Seal

There are different kinds of centrifugal pump mechanical seal, but the principle and structure is the same. Centrifugal pump mechanical seal`s main working parts are rotating impeller and stationary pump casing. Impeller centrifugal pump mechanical seal is directly on fluid power components, after several curved blade, generally for 4 ~ 8 pieces.When the centrifugal pump mechanical seal working, the impeller for high speed rotation driven by a motor (1000 ~ 3000 r/min), forcing the liquid also make rotation movement between blade. At the same time, because of the action of centrifugal force causes the liquid to the outer edge by the impeller center for radial motion. Liquid in the process of movement acquires energy, and leave the impeller outer edge at high speed into the volute pump shell. In the volute, due to the widening of flow reduction, a part of the kinetic energy is converted to static pressure, to achieve high pressure, finally along the tangential inflow pressure pipeline.

The liquid is forced to flow from impeller center to the outside, at the same time forming a vacuum in the center of the impeller. Pump suction pipe at one end and the impeller center are interlinked, another end is submerged in the transportation of liquid, the liquid surface pressure (often for atmospheric pressure) and pump pressure under the action of the differential pressure (pressure), the liquid inside the suction pipe into the pump, as long as the rotation of the impeller, suction and discharge liquid centrifugal pump mechanical seal. Thus are heavily dependent on high speed rotating centrifugal pump impeller centrifugal force generated by the transmission fluid, this is the reason that named centrifugal pump mechanical seal.

Richest offers a comprehensive range of centrifugal mechanical seal for most pump and agitator applications, single seal and balanced, replacement of John crane seal, for worldwide customers`choice from China based manufacturer. Richest Metal bellows mechanical seals are widely used in electric engines, transmissions, agricultural machines, bearing pedestals and rolling mills, with the advantages of sealing against dust, dirt, lubricant, oil and water spray from the outside.

Sodium Aluminum Phosphate Anhydrous

Sodium aluminum phosphate anhydrous is a white, odorless powder that is commonly used as a leavening agent in baking. It is a combination of sodium, aluminum, and phosphate ions and is often labeled as "SALP" on ingredient lists. It is used in a variety of food products, including cake mixes, breads, and biscuits, to help them rise and become fluffy. Sodium aluminum phosphate anhydrous is generally recognized as safe by the FDA and is considered a safe ingredient in food. However, it has been linked to health concerns when consumed in large amounts, such as kidney damage and osteoporosis.

Sodium aluminum phosphate anhydrous is a chemical compound with the molecular formula Na3Al3(PO4)4. It is a white crystalline powder that is commonly used as a leavening agent in baking powders and as a stabilizer in food products. It is also used in the production of ceramics, glass, and as a flame retardant. Sodium aluminum phosphate anhydrous is generally recognized as safe (GRAS) by the US Food and Drug Administration (FDA) for use in food products. However, excessive consumption of this compound may cause gastrointestinal distress and other health issues.
