What should be paid attention to for the shock absorber device on the pump
Everyone knows that shock absorbers can be installed on various pumps, mainly to reduce vibration and noise, and also to maintain pump performance and extend its life. Therefore, nowadays, shock absorbers are used when installing pumps, which is also the most advanced way to maintain pumps.
Although it is the best choice to equip the shock absorber with a pump, you should always pay attention to the installation. Different pumps and different installation methods have different matters to pay attention to, which is a necessary talent for the installation staff.
Methods and precautions for shock absorber installation on different pumps:
1. The electric butterfly valve shall be arranged symmetrically according to the central axis of the water pump unit, and the electric butterfly valve can be arranged clockwise or counterclockwise;
2. When the shock absorber of the unit has six installation points, four of them are arranged at the four corners of the inert block or section steel frame, and the other two should be arranged on the long side line, and their positions should be adjusted. The elastic bushing should make the compression deformation of the shock absorber as different as possible;
3. When the horizontal pump unit is equipped with a damping butterfly valve isolator, under normal conditions, the damper should be fixed with a connecting nut between the air, inert block or steel frame;
4. When the vibration isolator of vertical water pump unit is installed, the metal wire electric butterfly valve shall be installed under the base of the water pump unit, and an anchor type device shall be used. The section steel base and the electric butterfly valve shall be fixed with bolts (with butterfly valve gaskets). The foundation bolt is set in the air or floor, and the shock absorber is fixed in the air or floor after passing the foundation bolt;
5. The edge line of the electric butterfly valve shall not exceed the edge line of the inert block, and the supporting area of the metal electric butterfly valve section steel base shall not be less than the area of the shock absorber;
6. Before construction of the device, it shall be checked in time. During installation, the static tightening deformation of the electric butterfly valve shall not exceed the maximum allowable value;
7. When the pump unit is installed, the support of the low-frequency damping electric butterfly valve and the pump unit should be flat in the air, and should have sufficient bearing capacity;
8. The shock absorber of the unit shall be prevented from contacting with acid, alkali, organic solvent and other substances.
Only by understanding and applying the above precautions can the shock absorber be correctly installed on the pump, and the function and maintenance of the pump can be best experienced.
