Product overview
IR type pump is a horizontal centrifugal water pump, used in industry and agriculture and city, drainage, water supply for fire control. For pumping water and physical and chemical properties similar to water fluid does not contain solid particles. It is widely used in industry and agriculture and city, drainage, water supply for fire control.
Use and characteristics
? IR type pump is a horizontal centrifugal water pump, used in industry and agriculture and city, drainage, water supply for fire control.
? For pumping water and physical and chemical properties similar to water fluid does not contain solid particles. It is widely used in industry and agriculture and city, drainage, water supply for fire control.
? IR type pump system according to international standard IS02858 set forth in the performance and size of the design, the technical standards are drawn close to the international standards, reached the international advanced level. It is in our country to promote energy-saving pump products.
The pump has the advantages of simple structure, reliable performance, small volume, light weight, good anti-cavitation performance, low power consumption, convenient repair and use.
? IR type pump wide versatility, the whole series of 140 specifications, but only four shaft; the same specifications of the shaft, bearing, seal,
? Interchangeable; the series of pump suspension and only four.
? Pump speed is divided into 2900 and 1450 rpm two.
? Performance are as follows: 2900 rpm ~1450 rpm
? Maximum flow: 240 meters `400 meters 3 / 3 / min
? The highest total head: 125 m ~55 M
? Maximum speed: 3500 rpm (for the 60 wave modulated power supply, the impeller diameter decreased)
? The highest working temperature: 80 ℃
? Allowable suction line pressure 0.3Mlia, the maximum pump pressure 1.6Mlia.
Structure description
After the pump is open, open the pump cover and the impeller without removing the suction and discharge line. Suspension is provided with two ball bearings, machine oil or grease lubrication. Pump directly driven by motor through flexible coupling. Vortex chamber, water inlet and outlet flange flange foot, cast into a whole.
Water pump structure
1. IS, IR series pumps according to national standard ISO2858 the specified performance and size design, mainly composed of a pump body (1), a pump cover, an impeller (2) (3), axis (4), the sealing ring (5), Bush (8) and suspension bearing components (12) etc..
2. IS, IR type pump body and a pump cover portion, is from the back partition, namely after the open structure. The utility model has the advantages of convenient maintenance, maintenance Real pump, suction pipe, exhaust pipe and a motor, simply remove the lengthened coupling of the middle connector, to exit the rotor parts, repair.
3 pump shell (i. e., a pump body and a pump cover) constituted of a pump, impeller, shaft studio and rolling bearing for the rotor of the pump. Suspension bearing part supporting the pump rotor parts, rolling bearing pump radial force and axial force.
4 in order to balance the axial force of pump, the majority of the impeller of the pump before, after the sealing ring is arranged, and the impeller back shroud with balance holes, because some pump axial force is small, the impeller back is not provided with a seal ring and balance holes.
The 5 pump axial sealing ring is formed by the packing gland (9), packing ring (10), and a filler (11) such as composition, in order to prevent the intake or a large amount of water leakage. The impeller of the pump as a balance of. With soft stuffing cavity is communicated with the impeller suction inlet, the liquid is in a vacuum state if the impeller, it is very easy to be along the shaft surface air inlet, therefore in the filling cavity is provided with a packing ring through the pump cover through holes in pump chamber pressure water to the packing ring seal. The impeller of the pump without a balance hole, because the impeller back fluid pressure greater than atmospheric pressure, and therefore there is no problem of air leakage, so it can not be installed packing ring.
6 in order to avoid abrasion on shaft, through the packing chamber is provided with a protection sleeve and the shaft sleeve, fitted between the O sealing ring, along with air or surface to prevent water leakage.
7 drive pump through the elongated flexible coupling and motor coupling. Direction of pump rotation, seen from the drive end, for clockwise rotation.
