This standard replaces GB/T 19792-2005 "Agricultural irrigation equipment Hydrodynamic fertilizer - pesticide injection pump." This standard compared with GB/T 19792-2005, the main technical difference except outside editorial changes as follows. --- Adjusted normative references; --- GB/T 19792-2005 7.1 provision of irrigation water and injection water temperature of 5 ℃ ~ 50 ℃, the provisions of this standard 7.1 Irrigation Water injection and water temperature of 15 ℃ ~ 35 ℃; --- Anti-leak test, the water is injected into the negative pressure applied to the pump outlet, GB/T 19792-2005 provisions 5kPa ~ 10kPa, this Standard 10kPa (see 7.5.1); --- The standard delete GB/T 19792-2005 7.2 Sampling and acceptance criteria; --- Durability by the total running time of not less than 1000h should be changed to not less than 1150h (see 8.1). This standard uses redrafted law revision adopted ISO 13457.2008 "Agricultural irrigation equipment Hydrodynamic fertilizer - pesticide injection pump" (English Version). This standard and ISO 13457.2008 for the difference. --- On normative references, this standard has been adjusted technical differences, focus adjustments are reflected in Chapter 2, the specific Adjustments as follows. ● with the GB/T 7306.1 ~ 7306.2-2000 equivalent used in place of ISO 7-1.1994; ● with non-conformance with international standards equivalent to GB/T 17241.1 ~ 17241.7-1998 replaced ISO 7005- 2. 1988; ● Increase GB/T 9112 ~ 9124 "steel pipe flanges." The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee (SAC/TC201) Agricultural machinery centralized. This standard was drafted. Technical Research Center of Fluid Machinery Engineering, Jiangsu University, Chinese Academy of Agricultural Mechanization Sciences. The main drafters of this standard. Wang Yang, Zhang Xian wins, blue only, Li, Wang Xinkun, Zhao Liwei, the Qingjiang, Chen Chao. This standard replaces the standards previously issued as follows. --- GB/T 19792-2005. Agricultural irrigation equipment Hydrodynamic fertilizer - pesticide injection pump1 ScopeThis standard specifies the hydrodynamic fertilizer - pesticide injection pump (hereinafter referred to as hydrodynamic injection pump) structure, technical requirements and test methods for the moving of the water. Injection pumps for irrigation system to inject fertilizer - pesticides and fertilizers - pesticides including liquid manure, fertilizer and acid solution composition, pesticides, Grass like soluble pesticides. This standard applies to the temperature does not exceed 50 ℃, irrigation systems and water containing commonly used type and concentration of chemical fertilizers and pesticides running Hydrodynamic injection pump. This standard does not apply to reflux preventing means, it does not apply to irrigation systems inject fertilizer - pesticides Venturi hydrodynamic devices.2 Normative referencesThe following documents for the application of this document is essential.
