SZA Petrochemical Process Pump

1SZA Petrochemical Process PumpCharacteristics, principles, and images:
The execution standards for SZA series petrochemical process pumps (oil pumps) are AP1610 (8th edition) and VDMA24297 (light/medium). The SZA series petrochemical process pump is a single-stage single suction cantilever centrifugal pump. The SZA petrochemical process pump is mainly used for transporting clean or particle containing liquids, low-temperature or high-temperature liquids, neutral or corrosive liquids in industrial sectors such as petroleum, chemical, synthetic fiber, fertilizer, power station, metallurgy, food and medicine. The temperature of the conveying medium is generally -45 ° C to 180 ° C. The structural description of the SZA series petrochemical process pump is: A. The pump is a single-stage, horizontal, volute pump. The pump body is foot supported and has a single suction impeller. Axial suction, radial discharge. B、 According to the usage conditions, use front and rear seals and balance holes for hydraulic balance. C、 The packing box has cooling or heating pipe joints. The shaft seal adopts packing seal, and can also use single or double end mechanical seal. Equipped with cooling, flushing or sealing fluid system. D、 The rated pressure rating of the suction and discharge pipe flanges is the same. E、 Lubricate the bearings with clean No. 22 mechanical oil. F、 The rotation direction of the pump is clockwise when viewed from the prime mover end.

IISZA Petrochemical Process PumpType and code of shaft seal device
Single end mechanical seal S1 with built-in single end mechanical seal; S2 external single end mechanical seal; S3 has an internal single end mechanical seal with a rotating sealing ring (engagement ring). Both are unbalanced or balanced, with or without a throat liner.
Double end mechanical seal D1 back-to-back device double end mechanical seal; D2 series connection device double end mechanical seal; D3 face-to-face device dual end mechanical seal. One or both of them can be non-equilibrium living balance. If a double end mechanical seal is used, a sealing liquid with a pressure exceeding 0.5-1.0kg/cm2 of the working medium is required in the sealing chamber. The sealing liquid should be selected as a non-toxic and non corrosive liquid that does not affect the performance of the conveying medium.
Soft packing seal

IIISZA Petrochemical Process PumpPerformance Table Description
The data listed in the performance table are experimental data of a liquid at a standard atmospheric pressure, using a temperature of 20 ° C, a specific gravity of 1g/cm3, and a viscosity of 1mm2/s. ”The "head" value is the sum of the vertical height from the suction surface to the discharge surface plus the total head loss from the suction pipeline outlet to the discharge pipeline outlet (including bottom valves, gate valves, check valves, elbows, reducers, and pipe wall friction resistance in straight pipes).
As the viscosity of the liquid increases, its flow rate and head decrease, and power increases.
The pump body is pressurized at 2.5MPa (inlet pressure plus outlet pressure at zero flow), and users can determine the inlet pressure of the pump based on its own head value.
The principle of motor configuration is as follows: if the specific gravity is ≤ 1.0, the motor should be configured according to 1.0; If 1<specific gravity ≤ 1.35, equip the motor with 1.35; If 1.35<specific gravity ≤ 1.84, equip the motor according to 1.84.
