目前,正值汛期,旱涝交替,灌排机械得到了充分的利用。就离心泵排灌装置来说,受资金和其它因素的限制,对装置的抽真空充水引不起重视,配套不合要求。调查发现,每到灌排季节,抽真空充水困难,少则3—4人,多则4—8人,充水时间长达2—4小时,机泵启动4—8次,特别是真空井所配离心泵,启动往往达8次以上。这样既浪费了人力、物力,又浪费了电力,更有甚者,水泵不能运行,贻误农时。
At present, coincides with flood season, drought and flood alternation, irrigation and drainage machinery has been fully utilized. For centrifugal pump drainage and irrigation equipment, due to funding and other factors, vacuum pumping equipment can not afford to attract attention, supporting substandard. The survey found that every irrigation and drainage season, vacuum pumping water difficult, ranging from 3-4 people, as many as 4-8 people, filling time up to 2-4 hours, the pump starts 4-8 times, especially in the vacuum Well equipped with centrifugal pumps, often up to start more than 8 times. This is a waste of manpower, material resources, but also wasted power, what is more, the pump can not run, delaying farming time.
