Inline Water Booster Pump YG single stage single suction vertical pipe

Other similar circulating pump Use:

• ISG-type pipeline centrifugal pump for the delivery of water and physical and chemical properties similar to other liquids used in water, for industrial and urban water supply and drainage, high-rise building pressurized water, garden sprinkler, fire booster, long-distance transport, HVAC , Bathroom and other hot and cold water cycle pressurization and equipment, the use of temperature T <80 ℃.
• IHG vertical chemical pump for the transport of non-solid particles, corrosive, viscosity similar to the water liquid for petroleum, chemical, metallurgical, power, paper, food and synthetic fiber and other departments, the use of temperature -20 ℃ ~ 120 ℃.
• YG explosion-proof centrifugal pump, vertical centrifugal oil pump for conveying gasoline, kerosene, diesel and other petroleum products, the transmission medium temperature is -20 ℃ ~ +120 ℃.

IRG type hot water circulation pump Instructions for use:

First, before starting to prepare:

1. test motor steering is correct, from the top of the motor to the pump as a clockwise rotation, the test time is short, so as not to dry the mechanical seal dry wear.
2. open the exhaust valve so that the liquid-filled the entire pump, to be closed after the exhaust valve.
3. IRG vertical centrifugal pump before starting to check whether the normal parts.
4. hand pump to make the lubricant into the mechanical seal face.
5. High-temperature type should be preheated, the heating rate of 50 ℃ / hour, to ensure that the Department of heating evenly.

Second, start:

1. fully opens the inlet valve.
2. the vertical centrifugal pump starts to close the discharge pipe valve.
3. motor, observe the pump is running correctly.
4. check the shaft seal leakage, normal mechanical seal leakage should be less than 3 drops / min.
5. check the motor, bearing temperature rise ≤ 70 ℃.
6. adjust the opening between the opening to the required conditions, such as the user at the pump outlet with a flow meter or pressure gauge, the outlet valve should be adjusted by opening the pump in the performance parameters listed in the table, In the pump outlet is equipped with a flow meter or pressure gauge, should be adjusted by the outlet valve opening, measuring the pump motor current, the motor running in the rated current, otherwise it will cause the pump overload operation (ie, high current operation) Burned out. Adjust the export valve to open large and small and pipeline conditions.

Third, parking:

1. close the spit valve.
2. stop the motor.
3. vertical centrifugal pump stop when the imported valve.
4. such as long-term parking, the pump should be discharged to the liquid.
5. high-temperature type first cooling, cooling rate
