Pump base one: IS, IR horizontal single-stage single-suction centrifugal pump (1)

First, the use and characteristics IS, IR-type pump is a horizontal single-stage single-suction centrifugal pump for agriculture, agriculture and cities, drainage, fire and water supply. For the suction of water and similar physical and chemical properties of water-free solid particles of liquid. It is widely used in industry, agriculture and cities, drainage, fire and water supply. IS, IR type pump is designed according to the performance and size stipulated by the international standard IS02858. Its technical standards are all close to the international standards and reach the international advanced level. It is one of the energy-saving pump products promoted in China. The pump structure is simple, reliable performance, small size, light weight, good anti-cavitation performance, low power consumption, easy maintenance. IS, IR pump universal versatility, a full range of 140 kinds of specifications, but only four kinds of shaft; the same specifications of the shaft, bearings, shaft seal, interchangeable; full range of pump suspension only four. Pump speed is divided into two kinds of 2900 and 1450 rev / min. Performance is as follows: 2900 rev / min 1450 rev / min Maximum flow: 240 m 3 / min 400 m 3 / min Highest total head: 125 m 55 m Maximum speed: 3500 r / min Reduced) Maximum operating temperature: 80 ℃ Allow suction line pressure 0.3MPa, the maximum pump pressure 1.6MPa. Second, the structure that the pump for the rear open, open the pump cover and impeller without dismantling the suction and discharge piping. Suspension equipped with two ball bearings, with machine oil or grease lubrication. The pump is driven directly by the motor via a flexible coupling. Vortex chamber, feet, water flange and outlet flange cast as a whole. Third, the type of meaning IS, IR horizontal single-stage single-suction centrifugal pump water (performance parameters)
