Introduction to the application of ISG series single-stage single suction pipeline centrifugal pump

I. overview

isg series single-stage single suction pipeline centrifugal pump is a combination of scientific and technological personnel and domestic pump experts, which selects domestic excellent hydraulic model, adopts the performance parameters of is type centrifugal pump, and cleverly designs on the basis of general vertical pumps. At the same time, according to the use of different temperatures, media, etc., it derives applicable hot water High temperature corrosion-resistant chemical pumps, oil pumps. This series of products have the advantages of high efficiency and energy saving, low noise, reliable performance and so on, and meet the requirements of the latest jb/t standard of the Ministry of machinery of the people's Republic of China. The products are designed and manufactured according to the international ISO2858 standard

II. Main uses

g-type vertical pipeline centrifugal pump is used to transport clean water and other liquids with physical and chemical properties similar to clean water. It is suitable for industrial and urban water supply and drainage, pressurized water supply for high-rise buildings, garden sprinkler irrigation, fire pressurization, long-distance transmission, HVAC refrigeration cycle, bathroom and other cold and warm water cycle pressurization and equipment matching. The service temperature T is less than 80 ℃

g vertical hot water pump is suitable for high-temperature hot water pressurized circulating transmission of boilers in metallurgy, chemical industry, textile, wood processing, papermaking, restaurants, bathrooms, hotels, etc. and heating circulating pump of urban housing. The service temperature is below 120 ℃

g type vertical high-temperature centrifugal pump is widely used in: energy, metallurgy, chemical industry, textile, papermaking, as well as high-temperature hot water pressurized circulating transmission of boilers in restaurants, bathrooms, hotels and other places, as well as urban housing heating circulating pump. The service temperature is below 240 ℃

g vertical pipeline chemical pump is used to transport corrosive liquids without solid particles and with viscosity similar to that of water. It is suitable for petroleum, chemical industry, metallurgy, electric power, papermaking, food and pharmaceutical, synthetic fiber and other departments. The service temperature is -20 ℃ ~ 120 ℃

vertical pipeline oil pump is used to transport gasoline, kerosene, diesel and other petroleum products. The temperature of the transported medium is -20 ℃ ~ +120 ℃

gb vertical stainless steel explosion-proof chemical centrifugal pump is suitable for conveying flammable chemical liquids

gd, irgd, grgd, ihgh, YGd, ihgbd vertical low-speed centrifugal pumps are suitable for occasions with low environmental noise requirements and air conditioning circulation

III. features

1 The pump is a vertical structure with the same inlet and outlet diameters and located on the same central line. It can be installed in the pipeline like a valve. It has compact and beautiful appearance, small floor area and low construction investment. If it is equipped with a protective cover, it can be placed outdoors

2. The impeller is directly installed on the long 275 fire smoke exhaust fan shaft of the motor, with short axial size and compact structure. The bearing configuration of the pump and motor is reasonable, which can effectively balance the radial and axial loads generated by the pump operation, so as to ensure the smooth operation of the pump, low vibration and low noise

3. The shaft seal adopts mechanical seal or mechanical seal combination, adopts imported titanium alloy sealing ring, medium-sized high-temperature resistant mechanical seal and cemented carbide material. At present, the electronic tensile testing machine grinding seal is widely used, which can effectively prolong the service life of the mechanical seal

4. The installation and maintenance are convenient, and there is no need to dismantle the pipeline system. As long as the nut of the pump coupling seat is removed, all rotor components can be extracted

5. The series and parallel operation mode of the pump can be adopted according to the use requirements, that is, the needs of flow and head

6. The vertical and horizontal installation of the pump can be adopted according to the requirements of pipeline layout

IV. working conditions

1 The suction pressure is 1.0MPa, or the maximum working pressure of the pump system is 1.6Mpa, that is, the suction inlet pressure + pump lift is 1.6Mpa, and the pump static pressure test pressure is 2.5MPa. Please indicate the system working pressure when ordering. When the working pressure of the pump system is greater than 1.6Mpa, it should be put forward separately when ordering, so that when the most commonly used reinforcing agent is made of glass fiber and carbon fiber, the overflow part and connection part of the pump are made of cast steel

2. Ambient temperature < 40 ℃, relative humidity < 40%

3. The volume content of solid particles in the conveyed medium shall not exceed 0.1 per unit volume, and the particle size shall be less than 0.2mm

note: if the medium used is with fine particles, please explain it when ordering, so that the manufacturer can adopt wear-resistant mechanical seal
