Introduction of split case pump body:
Split case pump body is a component that directly determines the pressure bearing capacity, flow efficiency and service life of the pump. Our split case pump body is made of high-strength cast steel, which is suitable for mainstream medium-open pump models at home and abroad. The split case pump body can be widely used in urban water supply, industrial circulating water, and complex scenarios such as sand and high temperature.
Advantages of cast steel split case pump body:
1. Cast steel split case pump body is made of high-strength cast steel, which can meet the corrosion resistance and wear resistance of cast steel split case pump body in special scenarios such as chemical industry, mining, and seawater desalination.
2. Cast steel split case pump body is produced in strict accordance with ISO 2858 and GB/T 5657 standards, and is 1:1 compatible with the original pump body.
3. Cast steel split case pump body has high compressive strength and crack resistance, can withstand instantaneous pressure fluctuations, and is suitable for high-pressure scenarios.
Application scenarios of cast steel split case pump body:
Industrial field: cast steel split case pump body can be used in chemical plant media delivery and power plant circulating water systems.
Municipal engineering: stainless steel split case pump can be used for urban sewage treatment.
Agriculture and water conservancy: stainless steel split case pump can be used in reservoir pumping stations and reservoir irrigation systems.
Mining and energy: stainless steel split case pump can be used for underground drainage and metal slag slurry transportation in coal mines.
Stress test standards and methods of stainless steel split case pump:
Core standards: the pressure test of the stainless steel split case pump follows the general industry standards. The pressure of the stainless steel split case pump withstand pressure test is 1.5 times the working pressure, and the holding time is not less than 30 minutes. The stainless steel split case pump is qualified without leakage, deformation or structural damage.
Test method: assemble the split casing pumps and pump cover in the pretreatment link, close the inlet and outlet flanges, keep only one water injection port and exhaust port, and inject water into the split casing pumps through the water injection port to drain the internal air. During the pressurization test, an electric pressure test pump is used to slowly increase the pressure to the specified test pressure. After the pressure is reached, the valve of the pressure test pump is closed and the timing and holding pressure are started.
Daily maintenance techniques to extend the life of split casing pumps:
1. Regularly check the sealing and pressure of split casing pumps: check the seals of split casing pumps and pump caps every week. If leakage or aging is found, replace them in time. Record the working pressure of split casing pumps every month. If there is a sudden pressure fluctuation, check whether the pipeline is clogged or the valve fails to avoid split casing pumps from under abnormal pressure for a long time.
2. Control the cleanliness of the media of the split case centrifugal pump: install a filter before the inlet of the split case centrifugal pump to avoid solid particles entering the flow channel and wearing the inner wall. If the impurity-containing medium is transported, it is best to disassemble the split case centrifugal pump every quarter to clean up the residual impurities in the flow channel to prevent the deposition from causing local corrosion of the split case centrifugal pump or blockage of the flow channel.
3. Avoid dry operation and cavitation of split case centrifugal pump: make sure that the split case centrifugal pump is filled with medium before starting, otherwise the flow channel and sealing surface of the split case centrifugal pump will be damaged by friction and overheating.
