1. Rubber damping pads are arranged in a single layer. When the frequency ratio cannot meet the requirements, multiple layers can be arranged in series. However, the number of vibration damping pads should not be more than five layers. The rubber vibration isolating pads arranged in series shall have the same model, number of blocks, area and rubber hardness.
2, pad and steel application of adhesive bonding. The plane size of the galvanized steel plate should be 10mm larger than each end of the rubber cushion. The rubber cushions on the upper and lower layers of galvanized steel plates shall be staggered.
3. Before construction and installation, it shall be checked in a timely manner, and the static compression deformation of the damping element shall not exceed the maximum allowable value during installation.
4. When the pump unit is installed, the supporting surface of the pump unit installed shall be flat and shall have sufficient bearing capacity.
5, the unit damping elements should avoid contact with acids, alkalis and organic solvents and other substances.
6. The damping element should be symmetrically arranged along the center axis of the pump unit. The planar arrangement of the rubber cushion can be arranged clockwise or counterclockwise.
7. When the unit vibration-reducing element adopts six supporting points, four of which are arranged on the corners of the inert block or section steel frame, and the other two should be set on the long side line, and adjust its position so that the compression deformation of the damping element can be achieved. Keep as much as possible.
8. When the horizontal pump unit is installed with damping rubber damper or damper spring damper, under normal circumstances, there is an urgent need for rubber damper and damper spring damper and the ground, as well as between the inert block or steel frame. Bonding or fixing.
9. The edge of the rubber cushion shall not exceed the edge of the inert block; the bearing area of the steel frame shall not be less than the bearing area of the top of the damping element.
10. When the rubber damper is installed for vibration damping of the vertical pump unit, under the base of the pump unit, the steel frame should be installed and anchored; the bolt between the steel frame and the rubber damper (with spring washer added) )fixed. Anchor bolts are installed on the floor or floor, and the rubber damper is fixed to the floor or floor through the anchor bolts.
