Installation requirements for vibration isolation of pump pipes in water supply and drainage design of buildings

     1, pipe installation should be carried out after the installation of vibration isolation pump unit components 24h.

2, installed in the pump inlet and outlet pipes on the flexible rubber joints, valves and check valves must be near the pump side.

3, flexible rubber pipe fittings should be installed on the level of pipe.

4, flexible rubber pipe fittings should be installed in an unstressed natural state, is strictly prohibited in the extreme deviation state. , And flexible rubber pipe fittings connected to the pipeline should be fixed to the bracket, hanger, bracket or anchor.

5, flexible rubber pipe fittings can be installed, but also concealed. For buried pipes, should be located in the trench or inspection wells.

6, single ball, double ball flexible rubber joints can be installed on the pump suction pipe.

7, Flanged flexible rubber pipe fittings can be connected to the special flange and ordinary flange connection, the screw bolt should be towards the ordinary flange side. , Each end of the bolt symmetrical step by step uniform pressure tightening, all the bolts of the elastic, the degree should be consistent.

8, flange connection flexible rubber pipe fittings installed in series, the two flexible rubber pipe fittings flange loose flange should be added for the connection of a flat welding steel, blue.

9. When controlling the amount of compression or elongation displacement of a flexible rubber pipe fitting, a limit lever shall be provided between the two flanges of the flexible rubber pipe fitting.

10, flexible rubber pipe fittings should be kept clean and dry, to avoid direct sunlight and rain and snow dip.

11, flexible rubber pipe fittings, should avoid contact with acid, oil and organic solvents.

12, ordinary flexible rubber pipe fittings and fire and high temperature heat source distance should be 1m away.

13, flexible rubber pipe fittings can not be outside the paint brush.

Aluminum Forging Parts

Aluminum alloy materials are widely used in all walks of life due to their low density, high strength and stiffness, good corrosion resistance, and good processing performance. At present, the proportion of aluminum alloy forging in the aluminum alloy industry is still relatively small. Due to the relatively high cost of aluminum alloy forging, the production technology is relatively difficult, and most of them are used in parts that are particularly important in stress. However, with the rapid development of the aerospace and automotive industries, the demand for aluminum alloy forgings is increasing day by day. In particular, the forgings on the aircraft account for a large proportion, mainly aluminum alloy forgings, because the aircraft has relatively high requirements for strength and weight. There is also an increasing demand for aluminum forgings in the automotive industry. Therefore, our future task is how to improve and improve the aluminum alloy forging technology to meet the increasing demands of the aluminum forging industry.
