仍需往水泵和S形管中充水.开机后,吸水管到达必定真空后,水就被抽了上来,水泵进入正常工作状况.自吸真空所需求的时刻与进水管中空气的多少和水泵的转速有关,通常为4~8分钟.停泵后,泵和S形管中会积存必定的水,再开机就不必灌水了。线的交点M和M‘即为取消底阀前后的水泵实际工作点。

一.概述

1.用途：HW混流泵为卧式，单级，单吸，涡壳式混流泵。适用于输送清水或物理，化学性质类似于水的其它液体。被输送液体温度不宜高于50度。广泛用于农田灌溉，工业和城市排水等多种场合。HW泵的性能范围：流量90-9000m3/h    扬程3.5-22m。

2. 特点：结构简单，使用可靠，装修方便，而且效率高，体型小，重量轻。jdhuiquan5.15

3. 传动方式：用直接传动和变速传动。常用动力机是电动机和柴油机。订货   时应明确动力机的型号，以便确定联轴器和皮带轮的型号

4.型号说明：以150HW-8S例

5，其它部位漏液。处理办法：查看轴封等部位。6，泵叶轮阻塞，磨损，腐蚀。处理办法：清洁，查看，调换。五，扬程不行要素及处理办法如下：1，同二的1，2，3，4，三的1，四的6。处理办法：采纳相应措施。2，叶轮装反（双吸泵）。处理办法：查看叶轮。

二.结构和作用

1.HW pump mainly has pump cover, impeller, pump body, pump shaft, bushing, and bearing body and other major components. The pump cover is connected with the pump body and the inlet pipe respectively. 2. There should be an appropriate gap between the pump cover plane and the impeller plane. The gap is too small will produce friction, the gap is too large, will lead to the pump body pressure water a large number of reflux, is the pump efficiency reduction. The suitable gap used in practice is 0.3-0.7mm, and the gap can be adjusted by adding and subtracting the thickness of the paper pad.
3. The shaft is applied to protect the pump shaft and should be replaced in time after wear.
1. Screw holes at the upper end of the pump body, used for filling water diversion or connecting vacuum pump pumping gas to divert water. 
2. In order to expand the scope of application of the pump to meet the different needs of users, can cut the outer diameter of the impeller or exchange different performance of the impeller.
