压水机井,具有汲取浅层地下水、构造简单、施工方便、造价低、提水效果和水质好等优点。在广大农村、城郊居民和农户中,广为采用。其构造形式分为:插管压水机井和套管压水机井两种。但在压水时存在有一定弊病:如皮膜阀门密封不严,每当提水一次需加灌引水机筒内才能压上水,给提水带来一定的麻烦和困难。下面介绍的是经过多年使用的改进型压水机井,只需增加材料成本约十余元,就可解决密封不严、加灌引水的弊病。其具体构造是:1—机简(φ100～ Pressurized water wells have the advantages of capturing shallow groundwater, simple structure, convenient construction, low cost, good water lifting effect and good water quality. In the vast rural areas, suburban residents and farmers, widely used. The structure is divided into two types: intubation water pressure well and casing pressure water well. However, there are certain disadvantages when pressing water: if the membrane valve is not tightly sealed, water can only be put into the cylinder of the water pump whenever it is lifted, which will bring some troubles and difficulties to the lifting of water. The following describes the improved pressure water wells that have been used for many years. Only by increasing the cost of materials by more than ten yuan can we solve the shortcomings of lax sealing and irrigation and water diversion. The specific structure is: 1 - machine Jane (φ100 ~
