As an important equipment in the field of fluid transportation, stainless steel centrifugal pumps are widely used in chemical industry, medicine, food, water treatment and other fields because of their corrosion resistance and anti-pollution characteristics. However, reasonable installation is a key part of ensuring the normal operation and long life of stainless steel centrifugal pumps. Improper installation can result in reduced pump performance, damage or even safety hazards. This article will delve into the key things to pay attention to when installing a stainless steel centrifugal pump to ensure the stability of the equipment and the efficiency of fluid delivery.
The installation precautions for stainless steel centrifugal pumps are as follows:
Is the installation of stainless steel centrifugal pump reasonable，It has an important impact on the normal operation and life of the pump.Therefore installation and calibration must be done with caution.
Pre-embed the foundation bolts according to the installation dimensions and do the concrete foundation work well.
After the foundation cement is solidified, after installing the pump, use a level to check the level of the pump and motor shaft: if it is not level, use a backing plate to adjust it to level, and tighten the foot nut after adjustment.
Check whether the rotating parts of the pump are stuck. Strictly check the coaxiality of the pump shaft and motor, and rotate the coupling by hand. As long as the rotation is easy, even, and not stuck, it is normal.
The suction and discharge pipelines of the pump require their own brackets. The pump is not allowed to bear the weight of the pipeline directly to avoid damage to the pump.
When the pump is set higher than the liquid level (within the allowable suction range of the pump), a bottom valve is set at the end of the suction pipe, and a tap hole or valve for liquid injection before starting the pump is set on the discharge tube road; When the pump is set lower than the liquid level, please install a control valve and a wave-passing device on the suction pipeline to prevent foreign matter from being sucked into the pump. The sea-crossing area should be more than 3-4 times the area of the pipeline.
For high-lift pumps, a check valve should be installed on the outer pipe of the outlet flow control valve to prevent water hammer damage during sudden stop.
Ensure that the installation height of the pump is consistent with the gas margin of the pump, and the pipeline loss and medium temperature must be considered.
Before starting the pump, fill it with the supplied liquid. It is strictly forbidden to start without liquid.
Close the outlet valve and check the rotation of the pump immediately after turning on the power. The rotation direction of the pump must be consistent with the arrow. Reverse operation is strictly prohibited.
When the pump reaches normal speed after starting, slowly open the outlet valve and adjust to necessary conditions before starting operation. When the valve of the discharge pipe is closed, the pump must not work continuously for more than 3 minutes.
When stopping, please close the outlet valve first and then cut off the power supply.
In summary, the correct installation of stainless steel centrifugal pumps is an important step in ensuring their normal operation and extending their service life. During the installation process, sufficient preparation work should be carried out, including checking equipment, selecting suitable installation locations, and infrastructure construction. When installing inlet and outlet pipelines and conducting electrical wiring, pay attention to the firmness and correctness of the connections. By proper installation, reliable operation of stainless steel centrifugal pumps can be ensured, and efficient and corrosion-resistant liquid transportation solutions can be provided.
