Talk About The Role Of Slurry Pump Casings And Preparations Before Operation

Slurry pump is a conveying equipment widely used in mining, metallurgy, electricity, coal and other industries, and is mainly used to transport liquids containing solid particles.In slurry pumps, the pump housing is an important component, which plays a role in protecting and supporting internal components.The function of the slurry pump housing and the necessary preparations before operation will be described in detail below. First, let’s learn about the function of the slurry pump housing.The pump housing is the main part of the slurry pump, and its main functions are as follows: 1. Protective function: The pump housing can protect the internal impeller, shaft seal and other key components from the external environment, such as preventing solid particles from entering the impeller, preventing liquid leakage, etc.2. Kinetic energy rotation pressure: The pump housing is designed to slow down the speed of the liquid when it flows in it, and at the same time convert kinetic energy into pressure energy to facilitate the transportation of liquid.3. Sealing function: A sealing device is provided between the pump housing and the bearing seat to effectively prevent liquid leakage.4. Cooling function: A cooling water channel is provided on the pump housing, which can cool the liquid in the pump through cooling water, reduce the temperature of the liquid, and improve the working efficiency of the pump.5. Receiving and expelling liquid: The pump housing is responsible for receiving liquid from the impeller, which is thrown out after obtaining energy in the impeller.6. Supporting function: The pump housing provides stable support for internal impellers, shaft seals and other components to enable them to work normally.7. Provide strength and characteristics: The pump housing needs to have sufficient strength and good process characteristics to ensure stability and durability in continuous operation and harsh working conditions.After understanding the function of the slurry pump pump casing, let’s take a look at the necessary preparations before operation.In order to ensure the normal operation of the slurry pump and extend its service life, we need to make the following preparations before starting the slurry pump: 1. Check the inside of the pump casing: Check whether there are foreign objects inside the pump casing. If there are foreign objects, it needs to be cleaned in time.At the same time, check whether key components such as impeller and shaft seal are intact, and if there is any damage, they need to be replaced in time.2. Check the fasteners: Make sure all fasteners are complete and tight to prevent loosening during operation.2. Check the sealing device: Check whether the sealing device between the pump housing and the bearing seat is intact, and if there is any damage, it needs to be replaced in time.At the same time, check whether the lubricating oil in the sealing device is sufficient, and if it is insufficient, it needs to be added in time.3. Check the cooling water system: Check whether the cooling water system is normal. If there are any problems, it needs to be dealt with in a timely manner.At the same time, check whether the cooling waterway is blocked. If there is any blockage, you need to clean it in time.4. Check the power supply line: Check whether the power supply line is normal. If there are any problems, it needs to be dealt with in a timely manner.At the same time, check whether the power supply voltage meets the working requirements of the slurry pump. If it does not meet the requirements, adjust the power supply voltage.Safety protection device: Make sure that all safety protection devices are intact to ensure the safety of operators and equipment.5. Idle trial operation: Before it is officially put into operation, you can conduct an idle trial operation to observe whether the operation of the slurry pump is normal.If abnormal situations are found, please shut down and check in time.
