Product Overview
IS single-stage single suction (axial suction) centrifugal pump is an energy-saving pump jointly designed by the whole country. It is a newer type of BA, B and other single-stage clean water centrifugal pumps. Advantages: the whole series of hydraulic performance layout is reasonable, the user can choose a wide range, and maintenance is convenient; The efficiency and suction head have reached the international average advanced level. This type of pump is suitable for industrial and urban water supply and drainage, as well as agricultural irrigation and drainage, and for conveying clean water or other liquids with physical and chemical properties similar to clean water. The temperature is not higher than 80 ℃.
Product features
1. The IS type is designed according to the performance and dimensions specified in the international standard ISO2858, and mainly consists of the pump body, pump cover, impeller, shaft, seal ring, shaft sleeve and suspension bearing missing.
2. The IS type pump body and pump cover are divided from the back of the impeller, which is commonly referred to as the back door structure. Its advantage is that it is convenient for maintenance. During maintenance, the pump body, suction pipeline, discharge pipeline and motor are not moved, and only the intermediate connecting piece of the extended coupling needs to be removed to exit the rotor part for maintenance.
3. The pump housing (i.e. pump body and pump cover) forms the pump working chamber. The impeller, shaft and rolling bearing are the rotors of the pump. The suspension bearing component supports the rotor part of the pump, and the rolling bearing is subject to the radial force and axial force of the pump.
4. In order to balance the axial force of the pump, most pumps are equipped with sealing rings at the front and rear of the impeller, and balance holes are set on the rear cover plate of the impeller. Because some pumps have small axial force, there is no sealing ring and balance hole at the back of the impeller.
5. The axial seal ring of the pump is composed of the packing gland, packing ring and packing to prevent air intake or large amount of water leakage. If the impeller of the pump is balanced, the cavity with soft packing is connected to the suction port of the impeller. If the liquid at the impeller inlet is in a vacuum state, it is easy to enter air along the surface of the shaft sleeve. Therefore, a packing ring is installed in the packing chamber to lead the pressure water in the pump chamber to the packing ring through the small hole on the pump cover for sealing. If there is no balance hole in the impeller of the pump, since the liquid pressure on the back of the impeller is greater than the atmospheric pressure, there is no air leakage problem, so the packing ring can not be installed.
6. In order to avoid shaft wear, a shaft sleeve is installed at the position where the shaft passes through the packing chamber for protection. There should be an O-ring between the shaft sleeve and the shaft to prevent air intake or water leakage along the mating surface.
7. The drive mode of the pump is connected with the motor by lengthening the elastic coupling. The rotation direction of the pump is clockwise from the driving end.
Product use
IS and IR pumps are horizontal single-stage single suction centrifugal pumps for clean water and liquids with similar physical and chemical properties and without solid particles. It is widely used in industry, agriculture, city, drainage, fire water supply, etc.
