Code for installation of submersible pumps

1. Submersible pump installation, the weight of the pipeline to avoid to bear in the pump, the anchor bolts or expansion bolts are required to ensure complete installation time, and within a certain period of time to check to prevent loosening vibration.
2. In the installation of submersible pumps, install the import and export of pipe connections, and then fixed the anchor bolts of the pump, so that the installation sequence can avoid the installation of tensile stress, the pump has the appropriate damage. In principle, the installation of valves and soft connection (shock section) can facilitate the late maintenance of the pump, but also to reduce pipeline resistance and transmission efficiency, piping should be slightly larger than the pump inlet and outlet. (When the inlet pipe diameter larger than the diameter of the pump should be installed eccentric reducer, the tube plane position on the ramp in the next, to prevent the accumulation of air in the tube.Also, when connected with the diameter when the diameter, preferably in the The inlet with a straight tube, straight tube length greater than the diameter of 2 to 3 times or more)
3. Before installing the pump, consider the installation location of the rationality. The first to meet the pump suction vacuum height requirements, if the conditions can not meet the needs of the pump must be installed before the equipment to make adjustments, the second pump and pump, pump and pump room to maintain a reasonable position between the space for easy maintenance And other installation items, the third for special pumps need to pay attention to its installation precautions, read and understand the hands-on installation. Fourth, the installation location may be a natural or unnatural problems, such as noise, leakage, vibration, etc., you must do pre-installation isolation, insulation, sewage and so on.



4. Submersible pump Before connecting the pipeline, you should carefully check the submersible pump body with or without debris, such as wires, mounting tools, packaging materials or other hard objects, and promptly removed to avoid pump after the impact of pump quality and damage.
5. Water pump In the process of installation of pipelines, in order to facilitate the maintenance and safe use of imported water pump configuration a control valve, the export configuration of a pressure gauge and valves to ensure that the pump in the best conditions of operation. For Yang Cheng higher pumps, the export of the valve before the installation of one-way check valve to prevent the pump in a sudden shutdown of the water hammer to the destruction of the pump, thereby enhancing the pump life.
6. If the transmission medium containing debris, then debris is easy to enter the pump damage to the internal structure of the pump, and easy to block the export pipeline, the maintenance of great difficulties later, it should be installed in the pump inlet filter Network, filters, etc., to avoid a similar situation.
7. For suction pumps with a high degree of suction requirements, the submersible pump inlet must have strict requirements. First of all, consider the performance of the pump to meet the installation requirements, but also take into account when the pump running to bring the level drop caused by the height gap. The pump inlet pipe to ensure that no water leakage, no leakage, less elbow, minimize the length of the pump is not self-priming, but also need to consider the installation of the bottom valve, filters, filters and so on.
8. The basis of the pump to ensure that the installation of submersible pumps to maintain the level of the contact surface, the location and size of the hole set aside according to the actual size of the pump to decide. The use of vibration isolator or cushion when the need to take full account of the static and dynamic load of the pump,
9. For environmental reasons, when installing the pump, it must be equipped with a rain cover or a simple canopy to avoid external factors such as damage.
