High Chromium Alloys EXPELLER 028 Slurry Pump Spare Parts

Overview


The High Chromium Alloys EXPELLER 028 Slurry Pump Spare Parts is an important part of the expeller seal. The expeller fluid dynamic seal refers to the installation of an open impeller in the opposite direction of the coaxial direction near the back of the impeller rear cover of the pump. When the pump is working, the expeller rotates with the pump spindle, and the liquid in the expeller rotates together. The rotating liquid creates an outward centrifugal force that resists the liquid flowing to the mechanical seal and reduces the mechanical seal. pressure. On the other hand, the solid particles in the medium are prevented from entering the friction pair of the mechanical seal, which reduces the wear of the mechanical seal block and prolongs its service life.

The role of the centrifugal pump impeller: The mechanical energy of the prime mover is directly transmitted to the liquid to increase the static pressure and kinetic energy of the liquid to mainly increase the static pressure energy. The impeller has open, semi-closed and closed three open impellers without cover on both sides of the blade. It is easy to manufacture and easy to clean. It is suitable for conveying materials containing a large amount of suspended solids. The efficiency is low and the liquid pressure is not delivered. High; semi-closed impeller has no cover on the suction side and a cover on the other side, suitable for conveying materials that are easy to precipitate or contain particles, and the efficiency is also low; the closed impeller has on both sides of the impeller Front and rear cover, high efficiency.

Centrifugal pump impeller principle


The mechanical energy of the prime mover is directly transmitted to the liquid to increase the static pressure and kinetic energy of the liquid to increase the static pressure energy. The impeller generally has 6 to 12 back curved blades. The impeller has three types: open type, semi-closed type and closed type. The open impeller has no cover on both sides of the blade, which is simple to manufacture and convenient to clean. The centrifugal pump impeller is suitable for conveying materials containing a large amount of suspended solids, and the efficiency is low, and the liquid pressure delivered is not high; the semi-closed impeller is in the suction port. There is no cover on one side and a cover on the other side, which is suitable for conveying materials that are easy to precipitate or contain particles, and the efficiency is also low. The closed impeller has front and rear cover plates on both sides of the blade, which is highly efficient and suitable for use. Deliver clean liquid without impurities. The general centrifugal pump impeller is mostly of this type. The impeller has two suction and double suction modes. There is a single inlet for the water inlet, and it is double suction for water entering from both sides.
