Eccentric rubber coupling

Description

Products Description

Application:

Eccentric reducer rubber expansion joints serve to dampen vibrations and reduce noise, while also reducing the number of components required for pipeline installation, thereby lowering costs. They consist of an inner rubber layer, a fabric reinforcement layer, a middle rubber layer, an outer rubber layer, and end-reinforced metal rings or steel wire rings, all connected to metal flanges. These joints feature high pressure resistance, excellent elasticity, large displacement capacity, the ability to compensate for pipeline misalignment, effective vibration damping and noise reduction, and easy installation.

Features && Specification

Installing an eccentric reducer on a pump: This is done to prevent cavitation. Generally, the reducer at the pump inlet should be installed with the top flush with the surface. This prevents vapor from accumulating at the pump inlet, forming large bubbles that enter the pump chamber and damage the pump. There is only one scenario where bottom-flush installation is permitted: when the reducer is directly connected to an upward-curving elbow. In this case, vapor cannot accumulate.

2. Pump-Pipeline Installation of Reducers: When there is a size difference between the pump outlet and the external piping system, reducers are used to achieve a straight connection between two pipes of different sizes, serving as fittings for pipe diameter transitions.

Axial displacement of an eccentric rubber reducer refers to the elongation or compression of the rubber reducer in the direction of fluid flow (i.e., along the central axis).

Notes:1. For OEM orders with special requirement, rubber joints can be made according to customers' drawings. Material of rubber body can be NR natural rubber, EPDM, Neoprene, IIR butyl rubber, NBR Buna-N, FKM, etc. 2.When rubber joints size above DN200 are used for overhead water supply system, the pipes must be equipped with fixed supports or fixed brackets, otherwise control units shall be installed on rubber joints.
