Products made of stainless steel have gradually entered industrial applications because of their long service life, not easy to rust, and green environmental protection. Stainless steel pipeline pumps are among the best. The stainless steel pipeline pump included in the stainless steel pipeline pump has been widely used in the market in recent years, and is loved by the majority of users because of its corrosion resistance, long service life, light weight, safety and hygiene. Moreover, the cost of construction is comparable to that of ordinary sewage pumps, because the price of its brown metal has continued to increase over the years, and the price is almost the same. The used stainless steel material is a green and environmentally friendly material, which can be recycled 100%, so in recent years, it has become a leader in stainless steel high temperature and corrosion resistant submersible pumps. Especially in recent years, countries in the food industry have put forward higher requirements. Stainless steel materials have gradually entered the stage of history because of their safety and hygiene. For rigid requirements, stainless steel pump products represented by stainless steel submersible pumps have begun to shine in food products. With the sharp increase in the market, the stainless steel pipeline pump industry is facing new technological innovations. Various companies are also competing to launch their own killers, constantly improve their R&D teams, and study related core production technologies, so as to improve their competitiveness in the market. Pump products represented by stainless steel pipeline pumps are leading the entire pump industry to move forward, and the raw material market driven by this, new stainless steel materials continue to come out. Various patented technologies and the continuous improvement of specifications are constantly driving the entire industry chain to a higher and more orderly goal. At the same time, it is also expected that pump products led by stainless steel sewage pumps will go abroad and become more popular in the world. Play the pride of Made in China on the big stage.

Centrifugal pump test method and precautions for centrifugal pump test The installation of centrifugal pump should be completed in advance according to the following items when the centrifugal pump and centrifugal pump are installed 1. Before starting the centrifugal pump, it is forbidden to run the pump with no-load and no-load. The test run with liquid shall be carried out according to the operating procedures specified above in the operating instructions of the centrifugal pump. For the forced lubrication system, the temperature rise of the bearing oil of the centrifugal pump shall not exceed 28 ° C and the temperature of the bearing metal shall be less than 93 ° C. 2. For centrifugal pumps with oil ring lubrication or splash lubrication system, the temperature of lubricating oil shall not exceed 39 degrees, and the temperature of bearing parts shall be less than 82 degrees. 3. When testing the centrifugal pump, the vibration value of the bearing of the centrifugal pump should also be checked. The vibration standard of the bearing of the centrifugal pump can refer to the vibration standard of relevant Petrochemical rotating machinery. 4. During the test run of the centrifugal pump, the operation of the centrifugal pump should be very balanced and noise free, the coolant and lubricating oil system should be normal, and the centrifugal pump and auxiliary pipelines should be free of leakage. 5. During the commissioning of the centrifugal pump, it should be noted whether the current of the centrifugal pump motor operates within the specified range. If the overcurrent indicates that the actual working condition head is lower than the pump head, it is recommended to turn down the outlet valve to control the flow of the centrifugal pump so that its current can be used within the rated current range. 6. The leakage of various seals and media of centrifugal pump shall not exceed the requirements of the following standards: (1) Clean water centrifugal pump with mechanical seal: light oil 10 drops / min, heavy oil 5 drops / min (2) Multistage centrifugal pump with packing seal: light oil 20 drops / min, heavy oil 10 drops / min (3) For the magnetic drive pump conveying toxic, harmful, flammable and explosive media, no obvious leakage is allowed.
