Check the submerged mud pump oil room with or without water, if the water needs to check the reasons to troubleshoot and replace the oil; check the submersible mud pump impeller wear or cavitation, whether repair or replacement; check the submersible pump impeller And the seal ring between the pump body is too large to be replaced, whether the shaft of the submersible mud pump rust deformation or wear, motor bearings wear and tear; lack of signs of aging of the motor winding insulation, to the insulation resistance is too Low, three-phase winding resistance is balanced, whether there is hall sweep signs of damage between the rotor, the junction box with or without water, temperature, leakage protection components are normal, submersible mud pump motor internal and external fastening screws with or without release, cooling Set and circulating water pipes in the debris. Submersible mud pump removal inspection need to replace all 0-ring, check the protection of the main contactor circuit contactor oxidation or glitches, submersible mud pump thermal relay equipment is correct, the submersible mud pump pump level gauge is accurate , The ball movement is reliable. Pumping mouth and the surrounding deposition or clogging. Submersible mud pump pump room need to stop dredging and so on. For a long time do not have the submersible mud pump, should be raised, clean dry, upright dry and ventilated indoor storage.
　　
Only regular inspection and overhaul of the submersible mud pump can better understand the submersible mud pump and avoid the sudden failure of the submersible mud pump to work, which will affect the work of pumping sand, pumping ore powder and pumping mud, etc., affecting the construction period, reducing the manpower and material resources And financial resources. Therefore, we can see the importance of regularly servicing and maintaining the submersible slurry pump.

Galvanized Steel

Galvanized steel can be classified into two main types: hot-dip galvanized steel and electro-galvanized steel.

Hot-dip galvanization is the most common method of galvanizing steel. In this process, the steel is first cleaned and then immersed in a bath of molten zinc at a temperature of around 450°C. The zinc reacts with the surface of the steel, forming a series of zinc-iron alloy layers that provide excellent corrosion protection.

Electro-galvanization, on the other hand, is a process that involves using an electric current to deposit a thin layer of zinc onto the steel surface. This method is typically used for thinner gauge steel and provides a smoother finish than hot-dip galvanization. However, it may not be as durable as hot-dip galvanization and is typically used for less demanding applications.

In addition to its corrosion resistance, galvanized steel is also fire-resistant and has good thermal conductivity. It is also relatively easy to fabricate and can be formed into a wide range of shapes and sizes, making it a versatile material for various applications.

However, galvanized steel may not be suitablefor all applications. It has a shorter lifespan than some other corrosion-resistant materials, such as stainless steel, and may require regular maintenance to ensure its continued protection against corrosion. Additionally, galvanization can affect the appearance of the steel, giving it a characteristic dull gray or silver color that may not be desirable for some aesthetic applications.

Another consideration with galvanized steel is the potential environmental impact of the galvanizing process. The production of galvanized steel typically involves the use of large amounts of energy and resources, and the disposal of waste products from the galvanizing process can have environmental implications. However, efforts are being made to improve the sustainability of the galvanizing process, such as through the use of more energy-efficient production methods and the recycling of waste materials.

Overall, galvanized steel is a popular and versatile material that offers excellent corrosion resistance and durability. Its use is widespread in a variety of industries and applications, and it will likely continue to be an important material for many years to come.
