Hydrostatic seal. A hydrostatic seal is a non-contacting mechanical seal that operates under an equilibrium of forces. Unlike traditional hydrodynamic seals, hydrostatic seals have two different pressure zones that are used to establish a balanced pressure zone between two seal faces. [1] The two-pressure system makes the seal unique because ...
Hydraulic seal. A hydraulic seal is a relatively soft, non-metallic ring, captured in a groove or fixed in a combination of rings, forming a seal assembly, to block or separate fluid in reciprocating motion applications. Hydraulic seals are vital in machinery. Their use is critical in providing a way for fluid power to be converted to linear ...
A chest tube (also chest drain, thoracic catheter, tube thoracostomy or intercostal drain) is a surgical drain that is inserted through the chest wall and into the pleural space or the mediastinum. The insertion of the tube is sometimes a lifesaving procedure. The tube can be used to remove clinically undesired substances such as air ...
In mechanical engineering, an end-face mechanical seal (often shortened to mechanical seal) is a type of seal used in rotating equipment, such as pumps, mixers, blowers, and compressors. When a pump operates, the liquid could leak out of the pump between the rotating shaft and the stationary pump casing. Since the shaft rotates, preventing this ...
The simplest system that is sufficient for chest drainage is a one-chamber system. It uses either a Heber-drain or an active suction source and comprises a single collection canister. For active or passive air evacuation, a water seal component is attached. To ensure that all air is sucked out when using a Heber-drain, manual support might be ...
The Flowserve Corporation is an American multinational corporation and one of the largest suppliers of industrial and environmental machinery such as pumps, valves, end face mechanical seals, automation, and services to the power, oil, gas, chemical and other industries. [ 5] Headquartered in Irving, Texas, which is in the Dallas–Fort Worth ...
Hydrodynamic seal. A hydrodynamic seal is a type of mechanical seal. A hydrodynamic seal uses a dynamic rotor with grooves that act as a pump and create an air film that the opposing sealing surface will ride on. A hydrodynamic seal performs better than hydrostatic seals by providing greater film stiffness, lower leakage and lower lift off speeds.
Device to prevent fluid leaks in mechanisms. Compression seal example. A sealis a device or material that helps join systems, mechanisms or other materials together by preventing leakage(e.g. in a pumpingsystem), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealantsand ...
