Is, Iy, IR Type Single Stage Single Suction Horizontal Centrifugal Pumps

IS,IY ,IR type single stage single suction horizontal centrifugal pumps
 

Brief introduction

IS,IY ,IR type single stage single suction horizontal centrifugal pump  is an energy- saving pump designed by teamwork in the whole nation, it is improved on a basis on model BA, B and other single-stage water centrifugal pump. The advantages: its hydraulic capability is distributed reasonably, wide option for user, conveniently check and repair, the efficiency  is up to advanced international level. This pump is suitable for industrial and city water supply, water drainage , and widely used for agricultural irrigation, transportation pure water or other liquids which physical and chemical nature is similar to pure water, and the temperature should not be higher than 250°C.

Features

1. IS,IY ,IR type single stage single suction horizontal centrifugal pump  is designed according to the capability and size stipulated in the International Standard ISO2858, it is composed of pump body, pump cover, impeller, shaft, ring seal, sleeve and sus-p ended bearing units.
2. The pump body and pump cover in IS,IY ,IR type are separated from the back of impeller, that is to say in general, back open structure, whose advantages: convenient overhaul, when checking and repairing, the pump body intake  pipe, discharge pipe and motor need not to move, just disassemly the middle connector of extended coupling to quit the rotor units for overhaul.
3. The pump shell (that is pump body and pump cover) forms the workroom of pump.impeller, shaft and rolling bearing are the rotors for the pump. Suspended bearing units support the rotors in the pump. The rolling bearing stands the radial load and axial force.

Sand Casting is used to produce a wide variety of metal components with complex geometries. These parts can vary greatly in size and weight, ranging from a couple ounces to several tons. Some smaller sand cast parts include components as gears, pulleys, crankshafts, connecting rods, and propellers. Larger applications include housings for large equipment and heavy machine bases. Sand casting is also common in producing automobile components, such as engine blocks, engine manifolds, cylinder heads, and transmission cases.


Sand casting, the most widely used casting process, utilizes expendable sand molds to form complex metal parts that can be made of nearly any alloy. Because the sand mold must be destroyed in order to remove the part, called the casting, sand casting typically has a low production rate. The sand casting process involves the use of a furnace, metal, pattern, and sand mold. The metal is melted in the furnace and then ladled and poured into the cavity of the sand mold, which is formed by the pattern. The sand mold separates along a parting line and the solidified casting can be removed. The steps in this process are described in greater detail in the next section. In sand casting, the primary piece of equipment is the mold, which contains several components. The mold is divided into two halves - the cope (upper half) and the drag (bottom half), which meet along a parting line. Both mold halves are contained inside a box, called a flask, which itself is divided along this parting line. The mold cavity is formed by packing sand around the pattern in each half of the flask. The sand can be packed by hand, but machines that use pressure or impact ensure even packing of the sand and require far less time, thus increasing the production rate. After the sand has been packed and the pattern is removed, a cavity will remain that forms the external shape of the casting. Some internal surfaces of the casting may be formed by cores.


Sand casting is able to use of almost any alloy. An advantage of sand casting is the ability to cast materials with high melting temperatures, including steel, nickel, and titanium. The four most common materials that are used in sand casting are shown below, along with their melting temperatures

Materials              Melting temperature   
Aluminum alloys     1220 °F (660 °C)   
Brass alloys           1980 °F (1082 °C)   
Cast iron               1990-2300 °F (1088-1260 °C)   
Cast steel              2500 °F (1371 °C)   

The material cost for sand casting includes the cost of the metal, melting the metal, the mold sand, and the core sand. The cost of the metal is determined by the weight of the part, calculated from part volume and material density, as well the unit price of the material. The melting cost will also be greater for a larger part weight and is influenced by the material, as some materials are more costly to melt. However, the melting cost in typically insignificant compared to the metal cost. The amount of mold sand that is used, and hence the cost, is also proportional to the weight of the part. Lastly, the cost of the core sand is determined by the quantity and size of the cores used to cast the part.
