The standard for ZY oil pump: GB3215-92 universal technical conditions for centrifugal pump used for chemical and petrochemical process in smeltery.
Type ZY oil pump includes single-stage single-suction and two-stage single-suction cantilever type, single-stage double-suction cantilever type and two-stage double-suction both ends supporting type, two-stage single-suction both ends supporting type etc six kinds. Chart one to six are the structures and chart seven is type ZYP oil pump.
The radial split of pump, is especially suitable for delivering
In order to avoid removing suction or discharge line and easily remove impeller, shaft, shaft sealing and other components, ZY (P) oil pump uses extended coupling components of flexible diaphragm type to connect the motor directly. From the drive end, pump is counter-clockwise rotating.
Impeller is the whole cast, and by the static balance test, the pump axial force is mainly balanced by the impeller balancing hole.
Bearing body is with a radial ball bearings and a set of back to back installation of the thrust ball bearings, and the bearings use dilute oil to lubricate with oil slinger, and the cooling fin was cast on the bearing surface. It can be air cooling（T<120℃）, and choose fan cooling（T=120℃～260℃）and water cooling（T=260℃～420℃）.
high temperature, high pressure, flammable, explosive or toxic liquids. The installation is the horizontal centerline supporting, and the pump suction flange and outlet flange of type ZY, type ZYP are cast on the pump body,( 58364718,the inlet and outlet of type ZY is vertically upward; ZYP is axial suction, and outlet is straight up.) Shaft seal chamber (stuffing box) and the pump cover are cast into one, and it can fill with packing seals and balanced, bellows type, series type mechanical seals. There are selective water-cooled chamber jacket casting out of the shaft sealing chamber, and choosing water-cooled chamber should be based on special requests or the temperature of delivering medium-water exceeds 66 ℃, and the temperature of hydrocarbons exceeds 150 ℃.
Seal flush is defined by the different operation conditions of medium, its temperature and pressure. The sealing liquid amount of every seal chamber is in the following table,( 58364719,for both inside or outside).
The pressure of sealing liquid is usually 0.07-0.1MPa higher than that of seal chamber. If the medium delivered is easy to vaporize, it should be 0.175-0.2MPa higher than the vapor pressure.
According to the different using conditions, the main component materials can be four kinds and see the table below. (If any special requirement, please deal with our company)
Steam pipe is used when the medium temperature lowers and crystallization precipitating or solidification, and the pressure is about 0.1MPa.
