离心泵广泛应用于农业排灌、水利工程、农村饮水、植物保护、抗旱救灾等，是农民增产增收重要工具，是实现高产、优质、高效农业的有力保障。为了促进我国离心泵产品质量的不断提高，保证农业丰收和增加农民收入，国家质量监督检验检疫总局在1995年第1季度、1996年第2季度、1997年第2季度对离心泵产品质量实施国家监督抽查后，于2003年第1季度再次对其进行了国家监督抽查。 抽查概况 本次抽查了北京、天津、山东、河北、河南、山西等6省(市)27家企业的27个产品，抽查企业数约为全国离心泵生产企业总数的9%。抽查的企业中，既有国有企业和集体企业，也有私营、独资和股份制企业；有产量大、生产能力强的主导企业，也有产量小、生产能力低的非主导企业。抽查结果基本代表了目前我国离心泵行业的质量水平。 本次抽查结果按企业明示标准判定：合格产品23个，产品抽样合格率为85.2%。与1995年第1季度、1996年第2季度、1997年第2季度离心泵产品质量国家监督抽查的产品抽样合格率62.5%、87.9%、80.8%比较，这次抽查的合格率由60%左右跃升至相对稳定的80%以上。由此可以看出，离心泵产品质量持续提高，国家监督抽查对提高和稳定离心泵产品质量起到了极其重要的作用。 存在的主要质量问题 从抽查中发现，目前离心泵存在的主要质量问题有： 1.规定点流量扬程、规定点临界汽蚀余量、规定点效率等主要性能参数不符合要求。本次抽查中，主要性能参数存在不合格的产品有10个，占所检产品总数37.0%。 2.静平衡、标志项目不合格。主要是静平衡超差，标牌不规范等。本次抽查中静平衡、标志存在不合格的产品有22个，占所检产品总数的81.5%。 质量不合格的主要原因 1.有的企业生产、技术能力低，生产设备落后，加工、铸造工艺较差，无基本检测设备，导致其产品质量不合格。 2.有的企业未严格执行产品检验制度，生产的产品质量得不到有效监控。 3.有的企业刚转制完毕或处于转制阶段，其生产、管理较混乱，经济效益差，没有资金用于改进产品质量。 4.有的企业对非主导产品的质量不够重视，企业不愿花费过多的人力、财力去提高产品质量。 5.有的企业为抢占竞争激烈的离心泵产品市场，采取偷工减料，减少加工工艺环节等手段来降低成本，以低质低价冲击离心泵产品市场。 提高质量的措施 1.企业应增加技术投入，进一步提高离心泵产品技术含量。从本次抽查中产品的主要性能参数不合格的企业有10个，占所检企业总数的37.0%。这可以看出，目前我国离心泵行业技术水平不高。建议行业主管部门督促企业多方筹措资金，对产品进行技术改进、开发，生产技术含量高、性能优越又具有一定市场的离心泵产品。 2.企业应完善检测仪器设备，提高检验人员素质。本次抽查中不合格企业均存在检测设备不全或检测手段落后，检验制度执行不严的情况。建议企业应增加必要的质量投入，建立完善的质量检测体系，同时，加大对检验人员的培训，严格执行出厂检测制度，使产品质量始终处于受控状态。 3.加大监督抽查力度，整治市场经营秩序。目前，我国离心泵产品市场竞争激烈。部分企业为抢占市场，采取偷工减料、减少加工工艺等手段来降低成本，以低价低质产品冲击市场。为此，应加强监督抽查力度和后处理措施，着力整治市场经营行为，净化离心泵经营市场，给生产企业提供良好的竞争环境。

原文：
Centrifugal pumps are widely used in agriculture, irrigation, water conservancy, rural drinking water, plant protection, drought relief, are an important tool for farmers increase production is to achieve high-yield, high-quality, high-efficiency agriculture of the strong guarantee. In order to promote our product quality and continuous improvement of centrifugal pumps to ensure a good harvest and increase the income of the farmers, the State General Administration of Quality Supervision, Inspection and Quarantine in 1995 Q1, 1996 Q2, 1997 Q2, product quality, implementation of the centrifugal pump national supervision inspection, after a quarter of 2003 once again conducted a national supervision of their checks. Random profile The sampling of Beijing, Tianjin, Shandong, Hebei, Henan, Shanxi and other six provinces (municipalities) 27 products of 27 enterprises for testing, the number of enterprises around the country centrifugal pump 9% of the total number of manufacturing enterprises. Sample of enterprises, both state-owned enterprises and collective enterprises, but also private, wholly-owned and joint-stock enterprises; volume of production, strong production capacity of dominant firms, but also production of small, low production capacity of the non-dominant companies. Checks were basically represents the quality level of China's pump industry. The sampling results to determine an enterprise's explicit criteria: Qualified products 23, the product sample pass rate of 85.2%. 1995 Q1, 1996 Q2, 1997 Q2 centrifugal product quality of products of national supervision inspection pass rate of 62.5% sample, 87.9%, 80.8% compared to the random passing rate from 60% jumped to more than 80% of relative stability. It can be seen that centrifugal product quality continues to improve, the state supervision and checking of improving product quality and stability of centrifugal pumps has played an extremely important role. The main quality problems exist From the spot checks found that the current pumps are the main quality problems are: 1. The provisions of point flow head, provides the critical points, NPSH require-point efficiency of the main performance parameters did not meet the requirements. The spot checks, the main performance parameters of existing substandard products are 10, accounting for 37.0% of the total number of seized products. 2. Static equilibrium, marking the project failed. Mainly static equilibrium ultra-poor, signs are not standard. The sampling in static equilibrium, there is substandard products are marked 22, accounting for 81.5% of the total number of seized products. The quality of the main reasons for failure 1. Some production, technical capacity is low, backward production facilities, processing, poor casting, non-essential testing equipment, resulting in products of inferior quality. 2. Some enterprises did not strictly enforce the system of product testing, production and product quality can not be effectively monitored. 3. Some companies have just completed or in the conversion phase of restructuring, its production, management and more chaos, economic efficiency is poor, no funds be used to improve product quality. 4. Some of the non-dominant enterprise is not enough emphasis on the quality of products, businesses do not want to spend too much manpower and financial resources to improve product quality. 5. Some enterprises to seize the competitive market centrifugal pumps to take cutting corners to reduce the processing technology to reduce costs by means of links to the impact of low-quality low-cost centrifugal pumps market. Measures to improve the quality 1. Enterprises should increase the technical inputs to further enhance the technological content of centrifugal pump products. From this spot checks of the main performance parameters of product failure, there are 10, accounting for over seized total number of enterprises 37.0%. This can be seen that the current technical level of China's pump industry is not high. The proposed multi-sector authorities and urge enterprises to raise funds for technological improvements of products, development, production with high technological content, superior performance, but also has a certain market for centrifugal pump products. 2. Enterprises should improve the detection equipment, to improve the quality of inspectors. The spot checks have failed to pass the corporate existence of incomplete testing equipment or testing methods are backward, lax implementation of inspection system situation. Recommends that companies should increase the quality of the necessary inputs, establish a perfect quality inspection system, and at the same time, increase the training of inspectors and strict implementation of the factory inspection system so that product quality is always in control. 3. Step up supervision and sampling efforts and improve our operational order of the market. At present, China centrifugal product market competition. Some enterprises to seize the market, take jerry to reduce the processing technology and other means to reduce costs to low-cost low-quality products hit the market. To this end, efforts should be strengthened supervision checks and post-treatment measures, efforts to straighten out the market conduct of operations, cleaning centrifugal pump operating the market, to the manufacturers to provide a good competitive environment.
