TIME：2024-06-03 Author：admin Views：
In terms of performance, the Kdnny corrosion-resistant chemical pump has a steep drop in head curve and a relatively flat power curve. The common type of pressure chamber pumps are used in corrosion-resistant chemical,which is a volute, and in internally installed submersible corrosion-resistant chemical pumps, radial guide vanes or flow channel guide vanes are often used. There are three types of snail shells: spiral, annular, and intermediate (semi spiral).
Features of corrosion-resistant chemical pump products:
1. The corrosion-resistant chemical pump is a vertical structure with the same inlet and outlet diameters,it is located on the same centerl ine. It can be installed in the pipeline like a valve, with a compact and beautiful appearance, small footprint, and low building investment. If a protective cover is added, it can be used outdoors. Spiral volutes are basically not used in corrosion-resistant chemical pumps. The annular water pressure chamber is widely used in small corrosion-resistant chemical pumps due to its simple structure and convenient manufacturing.
However, due to the emergence of intermediate (semi spiral) pressure chambers, the application range of annular pressure chambers has gradually decreased. Due to the fact that the intermediate (semi spiral) pressurized water chamber has both spiral properties and high permeability of the annular pressurized water chamber. It has received increasing attention from manufacturers.
2. Low failure rate: The structure is simple and reasonable, and the key parts are equipped with quality matching, greatly improving the fault free working time of the entire machine. The corrosion-resistant chemical pump adopts a unique structure and a new type of mechanical seal, which can effectively transport solids and long fibers. Compared with traditional impellers, the impeller of this pump adopts a single or double channel form, which is similar to a curved pipe with the same cross-sectional size and has excellent flow resistance. Equipped with a reasonable volute chamber, the pump has undergone dynamic and static balance tests on the impeller, ensuring that the pump is vibration free during operation.
Weilai Environmental Protection Equipment Co., Ltd. has been engaged in the research and development and manufacturing of corrosion-resistant chemical pumps for many years, and has gained insights into the anti-corrosion measures for corrosion-resistant chemical pumps.
The media used in chemical pumps are generally corrosive, and there are generally two classification methods for corrosion: one is based on the mechanism of corrosion, and the other is based on the cause and appearance of corrosion.
According to the mechanism of corrosion, it can be mainly divided into electrochemical corrosion and chemical corrosion. Electrochemical corrosion mainly refers to the corrosion phenomenon caused by surface electrode reactions of metal materials in contact with electrolyte solutions.
This reaction is generally redox reaction, the main factor is the humidity of the environment as well as the temperature of the problem, chemical corrosion refers to the surface of the metal and its surrounding contact medium will occur more intense chemical reaction, so that the metal by a certain amount of damage, this corrosion induced by the causes of the main temperature is high, the environment is dry.Steel is widely used in 80 ℃ below, odium hydroxide solution within 30% concentration, there are many factories in 100 ℃, 75% below still use ordinary steel, although the corrosion increases, but the economy is good.
And according to the appearance of corrosion and cause classification can be divided into, peeling corrosion, industrial atmospheric corrosion, high temperature oxidation corrosion and marine atmospheric corrosion and so on.
How to maintain the bearings of self-priming centrifugal chemical pumps?
First, regular inspection of self-priming centrifugal chemical pump bearings will be worn or corroded after a long period of use, it is necessary to check regularly. If it is a new pump, in general, after 100 hours of operation, to replace a lubrication, thereafter, 500 hours of replacement can be, in addition, after 1500 hours of operation, it is necessary to flow the bearing on the grease replacement, the amount of oil should be appropriate, to be added to the specified position, and the amount of grease can not be more or less, otherwise it will affect the operation of the bearings, heat, resulting in damage to the bearings.
Second, choose the correct grease.
1. Bearing grease selection should be correct, and keep clean, sealed, do not fall into the dust and other debris, otherwise it will cause some damage to the bearing. The disassembly of the bearing should pay attention to not damage or contaminate the parts.
2. Drip free leakage: different materials of carbide seals, to ensure that different media transportation are no leakage.
Therefore, in the self-priming centrifugal chemical pump bearings to do maintenance work, must pay attention to the above contents, and in accordance with the correct way of maintenance, so that the bearing parts really play a maintenance effect. At the same time, in addition to the bearing components to do maintenance work, but also in each start-up equipment for work before, do a good job related to check to ensure that the components have no problem before starting to use.
