Selection of Several Types of Water Pump Impellers
CLICLS：699
The main working component of a water pump is the impeller, and different types of impellers are applied to different water pumps. Clean water pumps include long shaft deep well pump, diesel engine fire pump, long shaft fire pump and stainless steel submersible pump, with a wide range of models and materials. Generally, clean water pumps mainly use closed impellers. There are several types of pump impellers. What are the differences in application occasions? Nanjing Wangyang Pump is a professional pump manufacturer, which produces and sells various types of long shaft deep well pumps, long shaft fire pump, diesel engine fire pump, stainless steel submersible pumps, etc. The reliable performance and quality are favored by users.
1、 Closed impeller
Composed of blades and front and rear cover plates. The closed impeller has high efficiency and is difficult to manufacture. Most commonly used in centrifugal pumps. Suitable for conveying clean liquids with low viscosity, such as clear water and solutions, that do not contain particles.
2、 Semi open impeller
There are generally two types of structures, one of which is a front half open type, composed of a rear cover plate and blades. This structure has lower impeller efficiency and requires the use of adjustable clearance sealing rings to improve efficiency. The other type is the rear half open type, consisting of a front cover plate and blades, with an efficiency similar to that of a closed impeller. In addition to conveying liquid, the blades also have the sealing effect of a back blade or auxiliary impeller. The semi open impeller is suitable for conveying liquids containing suspended solids such as solid particles and fibers. The manufacturing difficulty of semi open impeller is relatively low, the cost is low, and the adaptability is strong. In recent years, its application in centrifugal pumps for refining and chemical industry has gradually increased, and it is used to transport clean water and liquids similar to clean water.
3、 Open impeller
Impeller with only blades and blade reinforcing ribs, without front and rear cover plates. The number of open impeller blades is 2 to 5. The impeller of a water pump has low efficiency and is rarely used, mainly for conveying liquids with high viscosity and slurry like liquids.
According to the customer's requirements for model selection and quotation, the long shaft deep well pump, diesel engine fire pump, long shaft fire pump and stainless steel submersible pump all achieve the same performance and quality, rich experience in installation and maintenance, and fast troubleshooting. Models such as fire deep well pumps and long shaft deep well pumps have a long service life and fewer malfunctions, making their use more convenient and safe for users.
