喷头是喷灌机具和喷灌系统中的关键基础件之一,它的性能的优劣不仅直接影响着喷洒质量,而且关系到机具和全系统运行的可靠性和经济性。近几年,由于我国各地从事喷灌机具研制的同志的共同努力,喷头工作的可靠性及水力性能均有了较大的提高,从而使喷灌技术在我国的应用得到了迅速地发展。为了探讨喷头今后的发展途径,本文将就(1)我国喷灌用喷头的发展及存在问题;(2)我国PY_1系列喷头与国外先进系列喷头的比较及差距;(3)发展我国喷灌用喷头的意见这三个方面提出我们的浅见。本文能达到抛砖引玉的作用,将是笔者的幸事。
Sprinkler sprinkler irrigation and irrigation systems is one of the key components, the performance of its advantages and disadvantages not only directly affect the quality of the spray, but also related to the reliability of the machine and system-wide operation and economy. In recent years, due to the joint efforts of comrades engaged in the development of irrigation equipment in various parts of China, the reliability and the hydraulic performance of the nozzle have been greatly improved, so that the application of sprinkling irrigation technology in our country has been rapidly developed. In order to explore the development of nozzle in the future, this article will (1) the development and problems of nozzle in our country; (2) Comparison and gap between PY_1 series of nozzles in China and foreign advanced series; (3) Development of nozzle Opinion these three aspects of our suggestion. This article can achieve the role of throwing bricks and stones, will be the author’s blessing.
