The ISG series single-stage single-suction pipeline centrifugal pump is designed by the scientific and technical personnel of the unit. The United Nations internal water pump experts choose the excellent domestic hydraulic model, use the performance parameters of the IS-type centrifugal pump, and design cleverly based on the general vertical pump. At the same time, suitable hot water, high temperature, and corrosive chemical pumps and oil pumps are produced on the basis of the ISG type according to different temperatures and media. This series of products has the advantages of high efficiency, energy saving, low noise, and reliable performance. Comply with the latest national machinery department JB / T53058-93 standard requirements. The products are designed and manufactured according to the international IS02858 standard.
Conditions of Use:
1. ISG type vertical pipeline centrifugal pump is used to transport clear water and other liquids with similar physical and chemical properties to clear water. Suitable for industrial and urban water supply and drainage, pressurized water supply for high-rise buildings, garden sprinkler irrigation, fire pressurization, long-distance transportation, HVAC refrigeration cycle, bathroom and other cold and warm water cycle pressurization and equipment supporting temperature T <80 ℃.
2. IRG (GRG) vertical hot water (high temperature) circulating pumps are widely used in: energy, metallurgy, chemical, textile, papermaking, and hotels such as boiler high temperature hot water pressurized circulation delivery and urban heating system circulation pumps. IRG type uses T <120 ° C, GRG type uses temperature T <240 ° C.
3, IHG vertical pipeline chemical pump for liquids containing no solid particles, corrosive, and viscosity similar to water. Suitable for petroleum, chemical, metallurgy, power, paper, food and pharmaceutical and synthetic fiber departments. 20 ℃ ~ 120 ℃.
4. YG type vertical pipeline oil pump is used to transport gasoline, kerosene, diesel and other petroleum products. The temperature of the medium to be transported is -20 ℃ ~ + 120 ℃.
5. ISGD vertical low-speed centrifugal pump, suitable for occasions with low environmental noise requirements and air-conditioning cycles.
Structural characteristics and working principle:
1. The pump is a vertical structure. The inlet and outlet diameters are the same and are located on the same center line. It can be installed in the road pipe like a valve, with compact and beautiful appearance, small footprint, and low construction investment. If a protective cover is added, it can be used outdoors.
2. The impeller is directly installed on the extension shaft of the motor. Short axial dimension and compact structure. The pump and motor bearings are arranged reasonably. 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. Imported Chin alloy seal ring, medium-sized high temperature resistant mechanical seal and hard alloy material, wear-resistant seal can effectively extend the service life of the mechanical seal.
4. Easy installation and maintenance. No need to disassemble the piping system. Just remove the pump joint seat nut to pull out all rotor parts.
5. The series and parallel operation modes of the pump can be adopted according to the requirements of use, namely the flow and the needs of Yang Cheng.
6. The vertical and horizontal installation of the pump can be adopted according to the requirements of pipeline layout.
