Vertical centrifugal pump. Centrifugal pump repair

ISG type vertical pipeline centrifugal pump is also called pipeline circulating pump, centrifugal pump, pipeline centrifugal pump, single-stage centrifugal pump, vertical pump, booster pump, hot water pump, circulating pump, etc. It is a hydraulic model and adopts IS type centrifugal pump The performance parameters of SG and SG type pipeline pumps are designed by clever combination on the basis of general vertical pipeline pumps. At the same time, suitable hot water pipeline pumps are derived from the ISG series pipeline pumps based on the use temperature and medium. High-temperature corrosion-resistant chemical pipeline pumps and pipeline oil pumps. ISG series products have the advantages of high efficiency, energy saving, low noise and reliable performance.

Working conditions of vertical pipeline centrifugal pump:
1. Suction pressure ≤, or pump system high working pressure ≤, that is, pump suction inlet pressure + pump head ≤, pump static pressure test pressure, please indicate the system working pressure when ordering. If the working pressure of the pump system is greater than that, it should be stated separately when ordering, so that the flow-through part and the connection part of the pump are made of cast steel.
2. Ambient temperature <40℃, relative temperature <95%.
3. If the volume content of solid particles in the conveyed medium does not exceed the unit volume, the particle size is less than.
Note: If the medium used is with fine particles, please specify when ordering so that the manufacturer can use wear-resistant mechanical seals.

Vertical multistage centrifugal pump
The key to the installation technology of ISG pipeline pumps, pipeline centrifugal pumps, clean water centrifugal pumps, and vertical single-stage centrifugal pumps is to determine the installation height of the centrifugal pump, that is, the suction lift. This height refers to the vertical distance from the water surface of the water source to the center line of the centrifugal pump impeller. It cannot be confused with the allowable suction vacuum height. The allowable suction vacuum height indicated on the pump product manual or nameplate refers to the vacuum value on the section of the water inlet of the pump. And it is measured under 1 standard atmospheric pressure and 20°C water temperature. It does not consider the water flow after the suction pipe is installed. The installation height of the pump should be the value that is left after the vacuum height is allowed to suck up and the loss of the suction pipe is deducted. ISG pipeline pumps, pipeline centrifugal pumps, clean water centrifugal pumps, and vertical single-stage centrifugal pumps must overcome the actual terrain suction. height. The installation height of the pump should not exceed the calculated value, otherwise, the centrifugal pump will not be able to pump water. In addition, the magnitude that affects the calculated value is the resistance loss head of the suction pipe.
The use temperature is below 240℃. Vertical stainless steel pipeline centrifugal pumps are used to transport liquids that do not contain solid particles, are corrosive, and have a viscosity similar to water. They are suitable for petroleum, chemical, metallurgical, electric power, paper, food, and synthetic fiber sectors. The operating temperature is -20 ℃~120℃. The pipeline explosion-proof oil pump is used to transport petroleum products such as gasoline, kerosene, diesel, and the temperature of the medium being transported is -20℃~+120℃. ISG pipeline pumps, pipeline centrifugal pumps, clean water centrifugal pumps, vertical single-stage centrifugal pumps, stainless steel explosion-proof pipeline pumps, are suitable for transporting easy-to-use chemical liquids. , IRGD, GRGD, IHGH, YGD, IHGBD vertical low-speed pipeline centrifugal pumps, suitable for occasions with low environmental noise requirements and air conditioning cycles. Unique advantages of pipeline pump ISG vertical pipeline centrifugal pump has compact structure, small volume and beautiful appearance. ISG pipeline pump.
The static pressure test pressure of the pump is 2.5MPa, please indicate the working pressure of the system when ordering. ISG pipeline pumps, pipeline centrifugal pumps, clean water centrifugal pumps, vertical single-stage centrifugal pumps, when the working pressure is greater than 1.6MPa, should be stated separately when ordering, so that the flow-through part and connection part of the pump are made of cast steel. Ambient temperature <40℃, relative humidity <95%. The volume content of solid particles in the conveyed medium does not exceed 0.1% of the unit volume. Granularity<0.2mm. Note: If the medium used is with fine particles, please specify when ordering so that the manufacturer can use wear-resistant mechanical seals. Pipeline pump mechanical seal maintenance and maintenance methods, mechanical seal is an important core of the water pump, if it is used carelessly, it will cause damage. It will be helpful for everyone to pass the following. The mechanical seal lubricant should be clean and free of solid particles. The mechanical seal is strictly prohibited to work under dry grinding conditions. ISG pipeline pump, pipeline centrifugal pump.
