IS, IR-type pump is a horizontal single-stage single-suction water centrifugal pump for industrial and agricultural and urban, drainage, fire water and so on.
For the delivery of water and physical and chemical properties similar to the water does not contain solid particles of liquid. It is widely applied to industrial and agricultural and urban, drainage, fire water and so on.
IS, IR-type pump according to the international standard IS02858 provides the performance and size of the design, its technical standards are closer to the international standard, reaching the international advanced level. It is China's promotion of energy-saving pump products.
The pump structure is simple, reliable performance, small size, light weight, good anti-cavitation performance, low power consumption, easy maintenance and use.
IS, IR-type pump wide versatility, a full range of 140 kinds of specifications, but only four kinds of shaft; the same specifications of the shaft, bearings, shaft seal, can be interchangeable; full range of pump suspension only four.
Pump speed is divided into 2900 and 1450r / min two.
Maximum operating temperature: 80 ºC
Allow the suction pipe pressure 0.3MPa, the maximum pump pressure of 1.6MPa.
The pump is open, open the pump cover and the impeller without removing the suction and discharge piping. The suspension is fitted with two ball bearings, lubricated with machine oil or grease. The pump is driven directly by the motor through a flexible coupling. The vortex chamber, the foot, the water inlet flange and the water outlet flange are cast as a whole.
IS, IR-type pump according to the national standard ISO2858 the performance and size of the design,Mainly by the pump (1), pump cover (2), impeller (3), shaft (4), sealing ring (5), sleeve and suspension bearing parts (12) and so on.
IS, IR pump part of the pump and cover, is from the back of the impeller, that is commonly referred to as the back door structure. The advantage is easy to repair, maintenance does not move the pump body, suction pipe, discharge pipes and motors, just remove the coupling of the middle coupling, you can exit the rotor parts, for maintenance.
Pump housing (ie, pump and pump cover) into the pump of the studio, impeller, shaft and rolling bearings for the recorded rotor. The suspension bearing part supports the rotor part of the pump, and the rolling bearing receives the radial force and axial force of the pump.
In order to balance the axial force of the pump, most of the pump before and after the impeller is equipped with a seal ring, and in the impeller rear cover with a balance hole, because some pump axial force is not large, the impeller is not set on the back of the seal ring and Balance hole.
The axial seal ring of the pump is composed of packing gripper (9), packing ring (10), and packing (11), etc., to prevent air intake or a large number of water leakage. If the impeller of the pump is balanced, the cavity with the soft packing is connected with the impeller inlet. If the liquid at the inlet of the impeller is in a vacuum state, it is easy to enter the air along the surface of the sleeve. Therefore, The small holes in the pump cover draw the pressure in the pump chamber to the fill ring to seal. Pump impeller if there is no balance hole, because the impeller back of the liquid pressure is greater than the atmospheric pressure, and therefore there is no leakage problem, it can not fill the packing ring.
In order to avoid shaft damage, the shaft through the packing cavity with the shaft cover protection, between the sleeve and the shaft is equipped with 0-shaped seal to prevent the intake or leakage along the mating surface.
The pump is driven by an extended elastic coupling to the motor. The direction of rotation of the pump, from the drive side, for the clockwise rotation.
