DWYK ,DLY multistage submerged centrifugal pump is a new type oil water transfer pump in oil fields. The pumps have the advantages of small area, convenient installation and operation and maintenance etc .The pumps can meet the needs of collecting oil and discharging oil and sewage.
Application:
The pumps are used to transport oil and oil-water mixture medium collected from oil Wells and oil stations. The pumps are used in the production plant, chemical plants, refineries and other units to transport all kinds of oil and the pumps can also be used to transport water and other liquids similar to water.
Performance range:
Flow range: 5 to 300m m3 / h
Head range: 15 to 300m
Viscosity range: 0 to 60cst. Liquids temperature: 0 to 200 degree Celsius
Features:
The pumps are vertical single-suction multistage sectional-type centrifugal pump, with the suction inlet of YDB pump at the bottom and vertically downward, and the discharge center is arranged horizontally.
The pumps have the characteristics of small volume, small area, low noise, no radial force produced when the radial guide vane is running, stable operation, high efficiency, and less exposed parts.
transmission
The pump is driven by an outdoor vertical explosion-proof motor mounted on the motor bracket and driven by a coupling.
The pump rotates counterclockwise from the motor end.
shaft sealing
The pump adopts the packing seal of low-pressure area shaft structure, safe and reliable, no leakage.
Bearing and balancing device
The upper part of the pump shaft is supported by double radial thrust ball bearings, the lower part of the pump shaft is supported by sliding bearings, the axial force of the pump is balanced by the balance drum or balance hole, the residual axial force is borne by the upper bearing. The upper bearings are lubricated with grease or thin oil, and the sliding bearings are lubricated by the conveying medium.
material of the pump
Materials can be selected according to different media. Ductile iron qt600-3 stainless steel 1Cr18Ni9Ti, or cast iron HT200
