1. The pump does not produce water or oil.
Possible causes: a. No liquid storage or insufficient liquid storage in the pump body.
Remedy: a, add enough.
Possible causes: b. The inlet and outlet valves are not open, the inlet and outlet pipes are blocked, and the impeller flow passage is blocked.
Remedy: b, check, remove obstructions.
Possible causes: c, the motor is running in the wrong direction, the motor phase is slow
Remedy: c. Adjust the motor direction and tighten the motor wiring.
Possible causes: d, the suction pipe leaks.
Remedy: d. Tighten the sealing surfaces to remove air.
Possible causes: e. Reduce suction or shorten the line.
Remedy: e. Insufficient imported water supply, too high suction stroke, or long suction line, check the line for repair.
Possible causes: f. Excessive pipe resistance and improper pump selection.
Remedy: f, reduce pipe bends, re-select the pump.
Possible causes: h, the density of the pumping medium is higher or the viscosity is higher
Remedy: h, dilute to reduce concentration or reduce viscosity.
2, the pump flow is insufficient
Possible causes: a. Check by 1 first.
Remedy: a, first press 1 to exclude.
Possible causes: b. Pipes, impeller flow passages are partially blocked, and scale deposits.
Remedy: b. Remove the obstruction and readjust the valve opening.
Possible causes: c, the voltage is low.
Remedy: c, voltage regulation.
Possible causes: d, impeller wear
Remedy: d, replace the impeller.
3, the power is too large
Possible causes: a. Exceeding the rated flow rate
Remedy: a, adjust the flow, close the small outlet valve.
Possible causes: b, the suction is too high
Remedy: b, reduce the suction
Possible causes: c, pump bearing wear
Remedy : C, replace the bearing
4, noise vibration
Possible causes: a. Unstable pipeline support
Remedy: a, stable pipeline
Possible causes: b, liquid mixed with gas
Remedy: b, reduce the degree of vacuum
Possible causes: c. Generate cavitation
Remedy: c, replace the bearing
Possible causes: d, bearing damage
Remedy: d, adjust by 5
5, motor heating
Possible causes: a, excessive flow, overload operation
Remedy: a, close the small outlet valve
Possible causes: b, rubbing
Remedy: b, check for exclusion
Possible causes: c. Motor bearing damage
Remedy : C, replace the bearing
Possible causes: d, insufficient voltage
Remedy: d, voltage regulator
6, the pump leaks or oil
Possible causes: a, mechanical seal wear
Remedy: a, replace
Possible causes: b. The pump body has sand holes or cracks
Remedy: b, weld repair or replacement
Possible causes: c. The sealing surface is not flat
Remedy: c, trimming
Possible causes: d, loose installation bolts
Remedy: d, fasten
The pump body consists of a suction chamber, a liquid storage chamber,
The scroll type, the liquid return hole, the gas-liquid separation chamber, etc., after the pump is normally started, the impeller sucks the liquid stored in the suction chamber together with the air of the suction line Φ
Into, and completely mixed in the impeller, under the action of centrifugal force, the liquid entrains the gas and flows to the outer edge of the wrap, forming on the outer edge of the impeller
It is made into a white foam belt with a certain thickness and a high-speed rotating liquid ring. The gas-liquid mixture enters the gas-liquid separation chamber through the diffusion tube. At this point, because the flow rate is sudden
Lower, the lighter gas is separated from the mixed gas Φ, and the gas continues to rise and exit through the pump discharge port. The degassed liquid returns to the reservoir,
And enter the impeller again by the return hole, and re-mix with the gas sucked from the suction line Φ inside the impeller, under the action of the high-speed rotating impeller, the cross flow
To the outer edge of the impeller... As the process continues, the air in the suction line Φ is continuously reduced until the gas is exhausted.
During the suction process, the pump is put into normal operation. Because the pump has this unique venting capacity, the two pumps can deliver liquids containing gases,
A bottom valve is required. The direct-coupled self-priming centrifugal oil pump has a good sweep function when used in a tanker.
"50" -- indicates pump suction diameter (mm) "ZX" -- indicates self-priming pump "L" -- indicates direct connection "12.5"-- indicates rated flow (IT13/h)
