Mobile pump stations are widely used in industry, smelting, municipal administration, agriculture and other fields because of their simple operation and instant operation. In order to ensure the use effect of the mobile pump station, the user should not only pay attention to the overall situation of the equipment, but also pay attention to its wearing parts, every part of any instrument is very important, the lack of any part will affect the overall work, any part of the damage will also make the instrument can not work as a whole. Let’s talk about the use of mobile pump station should pay attention to what wearing parts.
1 pump shell is generally cast iron, it is prone to crack by mechanical force or thermal stress. When the diesel engine pump in the work because of the impact of cavitation or in winter did not put off the pump shell water and frozen also easy to rupture, such as the damage of the heavy can not be repaired when the new pump shell should be replaced.Gasoline Portable fire pump
2. The pump shaft is generally carbon steel, but it is easy to damage due to manufacturing quality, use or installation. Pump shaft may appear cracks, bending, journal wear, thread damage, etc., may also appear fracture accident. If the damage is too serious to repair, a new shaft should be replaced.Gasoline Portable fire pump
3. The impeller is an important working part, made of cast iron (according to the working conditions can also be made into the corresponding anti-corrosion material). It is also easy to be damaged due to manufacturing quality and use. The impeller may appear cracks, cavitation surface formation of hole or perforation, long-term erosion to thin or partial grinding blade, and even debris crushed. Some defects can be fixed; Some defects can not be repaired, that is, should be replaced with a new impeller.
4. The bearing bush of sliding bearing is made of copper and tin alloy, which has poor wear resistance. It is one of the vulnerable parts that are easy to wear and burn out. Rolling bearings generally have an average service life of 5000 hours, but improper installation, long service time or poor maintenance, and easy to wear or damage. In addition to the individual parts of rolling bearings can be replaced with new ones, the whole parts are generally replaced.Gasoline Portable fire pump
5 mouth ring is also known as leakage or wear ring, it is one of the parts of diesel pump easy to wear. It can be repaired or replaced after wear. When replacing the new leakage reduction ring, its inner diameter should be configured according to the impeller inlet outer diameter. Such as impeller inlet outer diameter wear, can be turned processing, in order to eliminate grooves and ellipses, and then configure the inner diameter reduced leakage ring, impeller inlet outer diameter can be turned three times.
6 filler after a long time will become hard and lose elasticity, will make diesel engine water pump leakage, leakage, should be replaced with a new filler.
7 pump oil seal is rubber products, easy to wear and aging, generally to replace the new parts.
The above is the use of vulnerable parts of mobile pumping station matters needing attention, hoping to help you better use the equipment.
