Part one of a two part series by Lev Nelik. Get it as soon as Thu, Dec 3. There are During shaft rotation, the face materials heat up, wear and degrade quickly without a lubricating fluid film between them. If the seal is under compressed it will take minimal internal pump pressure to overcome the spring and cause leakage or not seal at all at startup. Depending on the pump type and the process variables, there are various mechanical seal types to choose from. Learn the basics of wear components and their role in system operation in this white paper. Protecting assets with real-time condition data. A common environmental control used in vertical applications is a recirculation line from the seal chamber to pump suction, but in some cases the seals run dry for too long before the fluid replaces the air in the seal chamber. The potential for energy savings and water use ratio (WUR) reduction can be identified swiftly if focus is placed on pump components such as mechanical seals. in which the rotating shaft passes through a fixed housing, or occasionally, the housing rotates around the shaft. Process and seal environmental controls greatly contribute to a cool, clean lubricating film at the sealing interface. Rather than two flat rings, the sealing interface is a polymer material deflected against a hard material. This is a dry-running condition that generates heat and quickly degrades the materials at the sealing interface. It reduces leakage between the pump and the surroundings to an absolute minimum. Mechanical seal for pump is a kind of dynamic seal assembly, which is widely used on the rotating shaft. 給水ポンプのよくあるトラブルにメカニカルシールからの漏水があります。メカニカルシールは消耗品の為、1年に1回の交換が推奨されています。交換作業の他、給 ポンプ点検はアクアフレンドにお任せ下 … Find out which technologies work best to keep centrifugal pumps from causing downtime in critical industrial processes. -ABPN) and eccentric screw pumps (-Vario), Available for standard (Cartex-ASPN) and big bore (Cartex-ABPN) seal chambers, Single seals with flush (-ASPN, -ABPN) and with quench combined with lip seal (-ASQN, -ABQN) or throttle ring (-ASTN, -ABTN), Available for standard (Cartex-ASDN) and big bore (Cartex-ABDN) seal chambers, Standard version with U-grooves, V-grooves optional (dependent of direction of rotation), Does not open in the event of buffer pressure failure, self closing at pressure reversal, Fully operational in both liquid and gas phases, Single, double, tandem and tandem seal with intermediate labyrinth arrangement available, Three different impeller connections available, Loosely inserted seal face provides self-adjusting capability. A static secondary seal stops leakage between components that do not move relative to each other.
