With the development of centrifugal pump technology, centrifugal pumps in China have gradually entered a stage of rapid development. The demand for centrifugal pumps in many industries is constantly expanding, from traditional centrifugal pumps to new types of centrifugal pumps. Their changes all indicate that China's centrifugal pumps have entered a new era, especially the use of stainless steel centrifugal pumps, which further illustrates this situation. Stainless steel centrifugal pump is a relatively special and special product, which has significant advantages:
(1) The stainless steel pump does not have problems such as cavitation damage or water injection.
(2) The stainless steel pump has a compact structure and occupies a small amount of space. Due to working underwater, the stainless steel pump can be directly installed in the sewage tank without the need to build a special pump room for installing pumps and machines, which can save a lot of land and infrastructure costs.
(3) The stainless steel pump device is easy to maintain. Small stainless steel gear pumps can be installed freely, while large stainless steel gear pumps are usually equipped with automatic coupling installation that can stop the automatic device. The device and maintenance are quite convenient.
(4) Stainless steel pumps have a long continuous operation time. Due to the coaxial connection between the pump and motor, the shaft of the stainless steel gear pump is short, and the weight of the rotating parts is light, so the load received on the bearings is relatively small, and the service life of the stainless steel gear pump is much longer than that of ordinary pumps.
The IH type chemical centrifugal pump produced by Shanghai Lanhai Pump Industry is a single-stage single suction (axial suction) cantilever centrifugal pump, used to transport liquids without solid particles that are corrosive and have a viscosity similar to water. Its markings, rated performance, and dimensions are equivalent, and it has the characteristics of wide performance range, high efficiency, high level of "three modernizations", and convenient maintenance. Its efficiency is on average 5% higher than that of the F-type pump, and it is an energy-saving product promoted by the country.
The IH series chemical pump is a single-stage single suction chemical centrifugal pump, which is an energy-saving updated product that replaces the F-type corrosion-resistant centrifugal pump. The structure of the IH series chemical pump is a horizontal radial split, with a rear door opening structure, and there is no need to disassemble the pipeline during maintenance. The pump body is axially sucked in, radially discharged, foot supported, and connected to the prime mover with an extended coupling. The pump bearings use clean No. 22 mechanical lubricating oil. Before the pump runs, lubricating oil must be added to the suspension to about 2mm above the centerline of the oil mark. The large diameter impeller is sealed with packing, and the secondary impeller is sealed (power seal).
The temperature of the medium transported by the IH type chemical centrifugal pump is -20 ℃ to 105 ℃. If necessary, a double end face sealed cooling device is used, and the temperature of the medium that can be transported is below 300 ℃. Suitable for conveying various corrosive or non polluting water like media in industries such as chemical, petroleum, metallurgy, power, papermaking, food, pharmaceuticals, environmental protection, wastewater treatment, and synthetic fibers.
The IH stainless steel chemical centrifugal pump, which has a wide range of application scenarios, has high efficiency, superior performance, good energy-saving effect, and is in line with the development direction of national new energy, and is worthy of attention.
