CZ chemical process pump structure

First, the product overview CZ horizontal chemical process pump is based on the CZ pump according to the American Petroleum Institute standard API 610 eighth edition of the transformation and design made in order to facilitate the upgrading of the device, the structure of the horizontal suspension , Radial section, rear single-suction single-stage structure, such as the use of extended coupling, can not move the motor and remove the pipeline under the premise of the maintenance pump. Can transport a certain corrosive, a certain temperature of the liquid. CZ chemical process pump Second, the product features 1, the standard requirements of high: CZ pump in the transformation according to the API 610 version 8 of the relevant technical requirements for transformation, higher than the original API 610 6th edition standards and national standards GB 3215-83 "Refineries, chemical and petrochemical processes centrifugal pump general technical conditions" and GB 5656-1994 "centrifugal pump technical conditions (II) category." 2, casting process new: DFCZ pump over-current pump components (such as the pump body, impeller, pump cover, seal ring, etc.), using precision silicone melt casting, flow channel size and stability; casting after the pickling process to remove the casting surface Residual attachments, to retain the nature of the metal, will not affect the delivery of casting attachment material. 3, double volute shell: part of the large diameter (80mm above) high-lift pump with double volute casing design, effectively solve the large-diameter high-lift pump radial pressure is too large. 4, cooling chamber: pump cover with water cooling chamber design, eliminating the transport medium temperature higher machine seals and bearings adverse effects. 5, mechanical seal: According to different conditions single-ended, double-sided or metal bellows structure, sealing performance and reliable. 6, back leaf: back impeller with impeller, and balancing holes together to balance the axial force, while reducing the pressure within the shaft seal cavity to improve the working conditions of the shaft seal. 7, bearings: bearings to enhance the heavy load, and the use of thin oil lubrication, bearing capacity and strong, high life expectancy (> 25,000 hours). 8, Coupling: for the choice of flexible pin or diaphragm coupling (elongated type for the diaphragm coupling), carrying capacity, transmission efficiency. 9, all sealed shaft: shaft through the impeller, bushings before and after the O-ring seal to ensure that the shaft is not in contact with the media and improve the life of the shaft. 10, high pressure capacity: the pump design pressure of 2.5 MPa, IH pump higher than 1.6 MPa. Third, the working conditions Flow: 13 ~ 2000 m3 / h Head: 14 ~ 160 m Temperature: -80 ℃ ~ +140 ℃ (common type) + 140 ℃ ~ +300 ℃ (with water cooling chamber) Caliber: 32 ~ 300mm Environment Temperature: ≤ + 40 ℃ System maximum working pressure: ≤ 2.5Mpa
