《GB/T 33548-2017微型电泵 性能评价规范》由TC201（全国农业机械标准化技术委员会）归口，TC201SC4（全国农业机械标准化技术委员会排灌设备和系统分会）执行，主管部门为中国机械工业联合会。
Introduction
GB/T 33548—2017 Standard Overview
This standard was proposed by the China Machinery Industry Federation and is managed by the National Agricultural Machinery Standardization Technical Committee. It is applicable to single-phase or three-phase micro-electric pumps with a power of ≤3.0kW.
Background and significance of standard formulation
With the development of agricultural mechanization and intelligence, micro-electric pumps are widely used in irrigation, gardening and other fields. This standard aims to unify performance evaluation methods, improve product quality and regulate the market.
| Performance level | Specified flow rate (Q) | Specified head (H) | Electric pump efficiency (η) | |||
|---|---|---|---|---|---|---|
| Grade 1 | Qg(1+5%) | Qg(1±5%) | HG(1+3%) | HG(1±3%) | 7DB +3.0 | 7DB +4.5 |
| Grade 2 | QG(1±5%) | Qg(1±8%) | HG(1±3%) | Hg(1±6%) | 7DB + 1.0 | 7DB +1.5 |
| Level 3 | Qg(1±8%) | QG(1±10%) | Hg(1±5%) | Hg(1±8%) | 7DB | 7DB |
Technical Evolution Analysis of Standards
Compared with the old standard, this standard has been improved in performance indicators, test methods and inspection rules. More stringent efficiency requirements have been introduced, and type inspection clauses have been added to ensure product quality.
Actual application cases
For example, when testing a level 1 micro electric pump, it is necessary to test it on a test bench with a measurement uncertainty of level 1. Its flow rate, head and efficiency must meet the requirements of the corresponding level in the table.
Implementation suggestions
Manufacturers should strictly follow the standards for product design and production, establish a complete inspection system, and ensure clear markings. Users should also choose suitable electric pumps according to the performance level to ensure the use effect.
