In addition to chemical pump installation ⑥ pipeline installation shall comply with the provisions of GB50235 ~ 1997 "Industrial metal pipe construction and acceptance of norms", there should meet the following requirements: internal tube and pipe ends should be washed clean, remove debris, and the sealing surface thread should injury; inhalation pipes and output pipes should have its own stand, petrochemical process pump prices, the pump may not directly support the weight of the pipe; flange face connected to each other should be parallel, threaded pipe joint axis response, the petrochemical process pump, not by the flange bolts or fittings to force the connection; after piping connected to the pump, the pump should review the accuracy of the original alignment, when discovered piping cause deviation, adjust pipe was; after connecting piping to the pump, ZA petrochemical process pumps, should not be performed on welding and gas cutting, welding and gas cutting when necessary, the pipe should be removed or to take the necessary measures and should prevent welding slag into the pump; pump suction and discharge piping configuration It should meet the design requirements, cz petrochemical process pump, when there is no predetermined time, according to. The provisions of GB50275 ~ 1998 Appendix II were. ⑦ pipeline lubrication, sealing, cooling and hydraulic systems should be kept clear cleaning clean; its provisions pressurized portion of the device technical documentation shall be tightness test. When not specified, it should be the existing national "industrial metal pipeline engineering construction and acceptance" requirement standards. ⑧ pump test run should be carried out after the commissioning of its subsidiary system alone normal. ⑨ pump should be conducted in the case of medium-commissioning, commissioning of media or alternative media should meet the design requirements. Chemical pumps in the chemical industry to highlight the importance of the chemical characteristics of the pump used in the chemical industry in the performance of mechanical products mechanical products, along with the type and nature of the claim is delivered chemical media change. Media Although sometimes mentioned here refers to water, oil, or other non-hazardous materials; however in most cases chemical medium refers to the number of very "horrible" chemical raw materials; for example, has some of the serious harm of media (toxic, corrosive and flammable media); especially those prone to chemical reactions, corrosion, erosion or the role of media containing solid or gaseous medium above ingredients diversified media workers change the chemical composition of the chemical elements ratio of the change would lead to the chemical nature of the medium. change; cause or increase the concentration of the chemical medium with special flow properties. (Example: diffusion medium, the polymer solution, etc.) so often on the purity of the chemical medium (高标准, polymers, electrolytes, etc.) made of particularly strict quality requirements, which are particularly stringent quality requirements can conveniently be achieved by suitable chemical pumps ze petrochemical process pump outlet |.
