It is used to transport clear water or liquid with physical and chemical properties similar to clear water, and the medium temperature is less than or equal to 80 ℃.
Structural features
Horizontal installation, horizontal axial suction, vertical upward direction of discharge outlet,(IY pump discharge outlet can be divided into right, left and upward direction from the suction end). Rotor parts can be drawn out for maintenance without dismantling the inlet and outlet pipelines during maintenance. Depending on the purpose of the shaft seal, packing seal can be used or mechanical seal is not required. Depending on the purpose, various pump materials are divided into ordinary cast iron, wear-resistant cast iron, cast steel, cast steel, cast stainless steel, etc, the pump cover is fixed on the middle bracket through the stop, and then the pump cover is clamped in the middle through the connection between the pump body and the stop of the middle bracket. The pump body is axial suction, radial discharge, foot support type, can be directly fixed on the base. The suspension part is fixed on the middle bracket through the stop, and is supported on the base by the suspension bracket. During maintenance, the inlet and outlet connection pipes, pump body and motor can be removed, and the rotor components can be removed for maintenance only by removing the intermediate connection of the extension coupling.
Main parts
The main parts are pump body, impeller, sealing ring, impeller nut, pump cover, sealing parts, intermediate bracket, shaft and suspension, etc.
Rotation direction
Through the elastic coupling and motor connection, from the drive end, the pump is clockwise rotation.

Starting and running:
1, turn the motor fan blade by hand, the impeller should be no jarring phenomenon, flexible rotation.
2. Turn the pump by hand to make the lubricating liquid enter the end face of the mechanical seal.
3. Irrigation and exhaust, open the inlet valve to make the liquid fully enter the pump cavity until the entire pipeline is filled with liquid, and ensure the sealing of the inlet pipeline.
4. Close the outlet valve to reduce the starting current.
5. Turn on the power supply, start to determine the correct running direction, and rotate clockwise from the fan blade end of the motor.
6, gradually adjust the opening of the outlet valve, try to make the pump work in the rated state.
7. During the operation of the pump, if noise or unusual sounds are found, stop and check immediately.
8, the normal mechanical seal leakage should be less than 3 drops/min, check the motor, bearing temperature rise <70 ℃, more than this value should check the reason.
Stop:
1. Close the valve of the discharge pipeline.
2. Cut off the power supply and stop the motor running.
3. Close the inlet valve.
4. If the pump is stopped for a long time, the liquid in the pump should be drained.

Fault phenomenon
Cause of failure
Exclusion method
1. The water pump does not produce water
a. The inlet and outlet valves are not opened, the inlet and outlet pipelines are blocked, and the runner impeller is blocked.
B, the motor running direction is wrong, the motor phase loss speed is very slow.
C, suction pipe leakage.
D, the pump is not filled with liquid, there is air in the pump cavity.
E, the inlet water supply is insufficient, the suction is too high, the bottom valve leaks.
F, pipeline resistance is too large, pump selection is improper.
A, check, remove the blockage.
B, adjust the direction of the motor, tighten the motor wiring.
C, tighten the sealing surface, eliminate air leakage.
D, fill the liquid and open the exhaust valve, exhaust air.
E, shut down, check, adjust (grid water pipe or with suction range use prone to this phenomenon).
F, reduce the pipeline curve, re-select the pump.
2. Insufficient water pump flow
A, first press 1. reason inspection.
B, pipe, pump flow impeller part of the blockage, scale accumulation, valve opening is insufficient.
C, low voltage.
D, impeller wear.
A, first press 1. exclude.
B, remove the blockage, re-adjust the valve opening.
C, voltage stabilization.
d. Replace the impeller.
3. Excessive power
A, exceed the rated flow use.
B, suction is too high.
C, pump bearing wear.
A, adjust the flow, close the small outlet valve.
B. reduced.
c. Replace the bearing.
4. Vibration of noise
a. Unstable pipeline support.
B, liquid mixed with gas.
C, produce cavitation.
D, bearing damage.
E, motor overload heating operation.
a. Stabilize the pipeline.
B, increase the suction pressure exhaust.
C, reduce the vacuum degree.
d. Replace the bearing.
e. Adjust by 5.
5. Motor heating
A, excessive flow, overload operation.
B, touch.
C, motor bearing damage.
d. Insufficient voltage.
a. Close the outlet valve.
B. Check and exclude.
c. Replace the bearing.
d. Voltage stabilization.
6. Water leakage of water pump
A, mechanical seal wear.
B, the pump body has sand hole or rupture.
C, the sealing surface is not smooth.
d. Loose installation bolts.
a. replacement.
B, welding repair or replacement.
c. Finishing.
d. Fastening.
