Selection, installation and use of slurry pump
2024-09-26
1. Before selecting the model, the working conditions should be examined as accurately as possible to ensure the correctness of the selection calculation;
2. After calculating the required clean water head of the slurry pump, consider the impact of impeller wear on the head, and increase the head by 10% when selecting the model. Select the specifications of the slurry pump based on this head and flow, and avoid selecting a larger head specification based on this head.
3. During installation, pay attention to the way the slurry pump is fed to avoid "bringing in bubbles". The slurry pool should also have a flow stabilizing device, and the slurry pool liquid pipe should be away from the slurry pump inlet pipe.
4. The inner diameter of the pipeline is related to the slurry properties, sedimentation flow rate, and flow rate. Under the premise that there is no pipeline blockage, appropriately selecting a large-mouth pipeline inner diameter is conducive to reducing pipeline wear, but the inner diameter of the mouth pipe should be less than 2 times the above value, otherwise it is easy to cause cavitation in the outlet pipe, which will reduce the head flow of the slurry pump.
5. Avoid running at a small flow rate. This can easily cause unstable flow of the slurry pump, and the radial force is large at this time, which can easily lead to broken shaft failure.

Principles and steps of pump selection
Pumps are a kind of general-purpose mechanical equipment with a wide range of applications. They are widely used in various sectors such as petroleum, chemical industry, electric power metallurgy, mining, shipbuilding, light industry, agriculture, civil and national defense, and they play an important role in the national economy. According to statistics in 2002, the output of pumps in my country reached more than 2 million units, and the power consumption of pumps accounted for more than 21% of the power consumption. Therefore, it is of great significance to greatly reduce the energy consumption of pumps for energy conservation.

Desulfurization pump is a kind of pump with a very wide range of applications.
Desulfurization pump is a kind of pump that can adapt to various working conditions, such as conveying acid, alkaline liquid or slurry; various corrosive slurries in the smelting industry; various dilute acids in the sulfuric acid industry; various sewage in the environmental protection industry, etc. This pump is both corrosion-resistant and wear-resistant, and has a wide range of uses. It has the following characteristics:
What are the common causes and solutions for slurry pump failures?
As a professional slurry pump manufacturer, we remind you: before starting, you should open the pump inlet valve and close the pump outlet valve. Then start the pump, and then slowly open the pump outlet valve after the pump starts. The size and speed of the pump outlet valve opening should be controlled by the pump not vibrating and the motor not exceeding the rated current.
