The single-stage vertical cantilever centrifugal liquid pump is a three-phase motor upper pump structure. This series of pumps has a compact structure, good bearing lubrication conditions, and good motor cooling effect. , High lift, wear-resistant double-sided mechanical seal is used between the pump and the motor.

Single stage vertical cantilever centrifugal liquid pump using environment:

1. The temperature of the medium is not higher than +40℃, the pH value is 6.5-8.5, the volume of solid impurities in the medium is not more than 0.1%, and the particle size is not more than 0.2mm.

2. Power supply: the frequency is 50Hz, the three-phase 380V, and the fluctuation range is 0.9-1.1 times the rated value.

3. The submersible depth of the electric pump does not exceed 5 m

4. The QY stainless steel submersible pump should run within the specified head range to avoid motor overload.

5. The electric pump should be equipped with a corresponding motor protection starter.

Notes for single stage vertical cantilever centrifugal liquid pump:

1. The specifications and performance of the submersible pump should conform to the actual use, and should be carefully checked before use.

2. The inner diameter of the outlet pipe used with the QY submersible pump should match the diameter of the electric pump.

3. The power supply capacity should be above 5.5 kVA, three-phase, 380 volts, AC 50 Hz.

4. When the submersible pump is electrified or pumping water, do not wash things, swim or work nearby, and do not let livestock go into the water nearby, in case the electric pump leaks electricity and causes electric shock casualties.

5. The submersible pump shall not pump water or muddy water with a large sand content.

6. If the stainless steel submersible sewage pump suddenly does not turn, or the water volume suddenly decreases significantly and other abnormal phenomena, it must be stopped for inspection, and the power must be cut off first, and then transported and disassembled.

7. The electric pump should be equipped with a motor protection switch (the factory has allotment). The action current of the protection switch has been set, and the user is not allowed to change it by himself.

8. It is not allowed to pull the cable of the electric pump forcefully at any time. When using the cable, check the cable thoroughly, and replace it with a new one immediately if it is found to be damaged.

9. Voltage fluctuations are allowed between 342 and 418 volts. If the ground of the electric pump is far away from the power supply, the cross-sectional area of ​​the wire should be appropriately enlarged.

10. A yellow-green two-color core wire with a grounding mark in the outgoing cable must be grounded. If there is no fixed ground wire, it can be buried with a 2-meter metal rod on the banks of rivers, lakes, ditches or in wet soil. Wire.

11. Before use, check whether the oil hole screws of the upper and lower covers are loose or leaking oil. The middle M8 screw on the outlet box is the factory pressure test, and it is strictly forbidden for the user to loosen it by himself.

12. Before running, use a 500V megohmmeter to measure the insulation resistance of the motor stator winding to ground in cold state. The minimum value should not be less than 5MΩ, otherwise it cannot be used. It should be used after removing the moisture.

13. Before use, it should be idle on the land for a few seconds to check whether the electric pump is running normally and whether the steering is correct.

14. The electric pump shall not be dehydrated. When the electric pump is working, pay attention to check the water level drop, and do not let the electric pump run on the water surface. The diving depth range of the electric pump is 0.5 to 3 meters.

15. The electric pump shall not be immersed in the mud and shall not be placed horizontally. It is recommended to use a bamboo basket or a wire basket outside the electric pump to prevent water and grass debris from clogging the pump impeller.

16. After the QY stainless steel submersible electric pump is started, if it is found that the water output is very small or no water is produced, it means that the rotation direction of the electric pump is reversed.
