摘要
以内镶贴片式为主的不同类型滴灌带为材料,研究不同温度下,滴头间距和滴头流量与滴灌带爆破压力的响应关系;常温常压下滴头流量的均匀性。不同类型的滴灌带试样在15、23、30、37、45℃进行爆破试验。结果表明,小于37℃时,温度与爆破压力呈负相关关系,45℃时,爆破压力值随温度的增加有回升的趋势。同一温度下,滴头间距和滴头流量越大,所承受的爆破压力越大,3种滴灌带的流量均匀性合格。
Different types of drip irrigation tapes with inlay patch as the main material were used to study the response relationship between dripper spacing and dripper discharge and burst pressure at different temperatures,and the uniformity of dripper discharge at normal temperature and pressure.Burst pressure experiments of different types of drip irrigation belt were conducted at the temperature of 15,23,30,37 and 45℃.The results showed that there was a negative correlation between the temperature and the burst pressure when the temperature was lower than 37℃,while when the temperature was 45℃,the burst pressure tended to rise with the increase of temperature;At the same temperature,the larger the dripper spacing and dripper discharge,the greater the burst pressure it will bear.It was found that the flow uniformity indexes of the three types of drip irrigation belts all were qualified.
