The chemical process pump is foot-supported, single-suction impeller, axial suction and radial discharge. The axial force is hydraulically balanced by front and rear port rings and balance holes. The shaft seal adopts mechanical seal, which can adopt single-end or double-end balanced container type, or packing seal. The mechanical seal is equipped with cooling, flushing or sealing liquid system. The sealing pipeline system is designed according to API specifications, suction and discharge flanges can be designed according to GB, DIN and ANSI standards.
Chemical process pumps have a wide range of performance and various forms. The shaft seal uses single-end or double-end mechanical seals and is equipped with cooling, flushing or sealing liquid systems. It is suitable for conveying clean or liquid containing a small amount of particles, low-temperature, high-temperature, neutral and corrosive liquids. It is suitable for oil refining, petrochemical industry, coal processing and low-temperature engineering, papermaking, metallurgy, medicine, synthetic fiber, power generation, environmental protection, etc. Petrochemical process pump is a single-stage single-suction cantilever volute pump. The product implements standard API610,VDMA24297 (light/medium). The pump body is foot-supported, single-suction impeller, axial suction and radial discharge. The axial force is hydraulically balanced by the front and rear mouth rings and balance holes.
The chemical process pump is a single-stage single-suction cantilever type rear-opening structure, so there is no need to disassemble the suction and discharge pipelines when overhauling the pump. After disassembling the pump cover, the suspension can be pulled out from the pump body together with the rotor components, so the overhaul is very convenient. There is a sealing ring on the back cover of the impeller, which can basically balance the axial force, and the residual unbalanced force is borne by the thrust bearing. Petrochemical process pump bearings are oil-lubricated ball bearings. The oil ring can lift oil and automatically control the oil level. When the working temperature is lower than 250°C, the suspension does not need to be cooled. When the working temperature is higher than 250°C ~ 450°C, the suspension Air-cooled or water-cooled.
Chemical process pump according to different circumstances, part of the pump for the double volute structure, the rest of the single volute. The shaft seal can adopt packing seal, and can also adopt single-end or double-end mechanical seal, and is equipped with cooling, flushing or sealing fluid system, which is directly driven by the motor and connected with the motor by coupling. Petrochemical process pump is suitable for conveying clean or containing a small amount of particles, low temperature or high temperature liquid; Suitable for conveying neutral or corrosive liquids, including various temperatures and concentrations of sodium hydroxide and sodium carbonate and other alkaline solutions, various salt solutions, various acid solutions and salt solutions, various liquid petrochemical products, organic compounds and other corrosive raw materials and products.
Chemical process pumps are mainly used in refineries, petrochemical industry, coal processing industry and low-temperature engineering, paper industry, sugar industry and seawater desalination projects. ZA petrochemical process pump is a single-stage, horizontal radial split volute pump with foot support, single suction radial impeller, axial suction and radial discharge. According to the conditions of use, the front and rear wear rings and balance holes are used for hydraulic balance. The stuffing box has cooling or heating pipe joints, and the shaft seal adopts packing seal. It can also adopt single-end or double-end mechanical seal, and is equipped with cooling, flushing or sealing liquid system. The standard pipeline of petrochemical process pump is designed according to API specification. The rated pressure rating of the suction and discharge pipe flanges is the same. Seen from the motor end, the pump rotates clockwise.
Chemical process pump conditions of various temperatures and concentrations of sulfuric acid, nitric acid, hydrochloric acid and phosphoric acid and other inorganic and organic acids, various temperatures and concentrations of sodium hydroxide and sodium carbonate and other alkaline solutions, a variety of salt solutions, a variety of liquid petrochemical products, organic compounds, and other corrosive raw materials and products. At present, the corrosion-resistant materials of our factory can meet the requirements of various media mentioned above. When ordering, please provide the details of the medium to be transported.
CZ type chemical pump is a single-stage, single-suction centrifugal pump; its size and performance meet the requirements. CZ series chemical pump performance range includes all the performance of the chemical pump, its efficiency, cavitation performance and other indicators are more than ih type pump. CZ series chemical pumps deliver low or high temperature; neutral or corrosive; clean or containing solid particles. It is especially suitable for chemical and petrochemical industries; oil refineries; paper mills and pulp industry; the design features of cz-type chemical pumps in the grain industry. The pressure mainly acts on the shaft seal is balanced by the balance hole on the blade or impeller. The shaft seal can adopt soft filling seal (cooling, also can not cooling), can also use a variety of structures of single and double non-balanced mechanical seal. The ball bearing is durable and the shaft diameter is abundant to ensure smooth operation. Part of the specifications of the pump body is designed as a double screw housing to balance the radial force. The bearing frame, including the shaft, impeller, stuffing box, etc., forms a piece, so that the pump body does not need to be removed from the pipeline (if the coupling is used, the motor does not need to be removed). Flange design, using pn16, pn25 two (according to the material difference).
