Key factors for installation

The following is the Key factors for installation to obtain good performance and prolong the flange Pump Station Rubber Expansion Joint .

Fixed points:

An Pump Station Rubber Expansion Joint  acts as a piston by the forces arising from the internal pressure. To prevent the pipes from damage they are to be properly anchored to take care of these reaction forces (Fr).

The Reaction force of an Pump Station Rubber Expansion Joint  is calculated by the following formula:

Fr = Q x P x 0.01

Fr = reaction force in kN.

Q = effective cross-sectional area in cm2.

P = actual pressure in bar or KP/cm2

Installation:

The turnable metal flanges make installation easier and eliminate twists.

The low inherent rigidity of Songjiang Pump Station Rubber Expansion Joint  makes for easier accommodation of installation dimensions.

Check the permissible movements, temperature, pressure, and proper rubber quality before installation!

100% virgin material Pump Station Rubber Expansion Joint   installation suggestionThe Pump Station Rubber Expansion Joint   shall be easily accessible and open to regular supervision. Lt is recommended to let the Pump Station Rubber Expansion Joint   work in compression rather than stretching. Torsion is not permitted.Maintenance instructions: observe whether the rubber joint is overstretched and keep the flange Pump Station Rubber Expansion Joint   at normal length every month.Pressure-restrained expansion joint on the pump (with tie bar).

 

Counter flanges:

The safe operating and life expectancy of the Pump Station Rubber Expansion Joint  needs to make a proper installation of the counter flanges(Fig. 2 to 5). The sealing face of the counter flange must be machined smooth and cover most of the rubber sealing face(or at least 60%)to ensure good sealing(Fig.2).
