Features and uses:
IS type single-stage single-suction centrifugal pump is suitable for industrial and urban water supply and drainage, as well as agricultural irrigation and drainage. It is used for conveying clean water or other liquids with similar physical and chemical properties to clean water, and the temperature should not be higher than 80ºC. Seen from the transmission direction, the water pump rotates clockwise.
Performance range:
Flow: 6.3-460m³/h
Head: 5-125m
IS centrifugal pump, a new single-stage single-suction horizontal water centrifugal pump designed according to the performance and size specified in the international standard ISO2858, its technical standards are close to international standards, wide versatility, a total of 140 specifications, but only four shafts; The shaft, bearing, shaft seal, impeller fasteners of the same specification can be exchanged; There are only four suspensions for the full range of pumps. Reach the international advanced level. It is one of the energy-saving pump products promoted in our country. The pump is open back, and it is not necessary to disassemble the suction and discharge pipes when disassembling the pump cover and impeller. The suspension is fitted with two ball bearings which are lubricated with machine oil or grease. The pump is driven directly by an electric motor through an elastic coupling. The cochlear chamber, foot, inlet flange and outlet flange are cast as a whole. For suction and delivery of clean water and physical and chemical properties similar to water without solid particles of liquid. It is widely used in industry, agriculture and cities, drainage, fire water supply and so on.
The part of the pump body and the pump cover of the centrifugal pump are divided from the back of the impeller, that IS, the commonly referred to as the rear door structure. Its advantage is convenient maintenance, maintenance does not move the pump body, suction pipe, discharge pipe and motor, just remove the middle coupling of the extension coupling, you can exit the rotor parts, maintenance.
The pump housing (that is, the pump body and the pump cover) constitutes the pump workshop, impeller, shaft and rolling bearings, etc., for the rotor of the pump. The suspension bearing components support the rotor components of the pump, and the rolling bearings bear the radial and axial forces of the pump.
In order to balance the axial force of the pump, the front and back of most pumps are provided with a sealing ring, and a balance hole is provided on the back cover of the impeller, because some pumps have little axial force, there is no sealing ring and balance hole on the back of the impeller.
The axial sealing ring of the pump is composed of packing gland and packing to prevent the intake air or a large amount of water leakage. If the impeller of the pump is balanced, the cavity equipped with soft packing is communicated with the inlet of the impeller. If the liquid at the inlet of the impeller is in a vacuum state, it is easy to intake air along the surface of the shaft sleeve. Therefore, the packing ring is installed in the packing chamber and the pressure water in the pump room is led to the packing ring for sealing through the small hole on the pump cover. If the impeller of the pump does not have a balance hole, because the liquid pressure on the back of the impeller is greater than atmospheric pressure, there is no air leakage problem, so the packing ring is not installed. In order to avoid shaft wear, the part of the shaft through the packing chamber is equipped with shaft sleeve protection, and the shaft sleeve is equipped with an ○ sealing ring between the shaft and the shaft to prevent air intake or water leakage along the matching surface.
The transmission mode of the pump is connected with the motor by an extended elastic coupling. The direction of rotation of the pump, from the driving end, is clockwise.
