买洒水车挑选什么样的好洒水车使用操作技术，洒水车使用过程中洒水量大小分析洒水车主要有降温消暑、道路压尘、净化空气等功能。多功能洒水车还的具备消防、农药喷洒、高空作业等其它功能。今天，就以环卫绿化洒水车为例，来解析一下洒水车洒水量大小的问题：洒水车洒水量的大小，没有一个标准的参数，实际应取决于被洒地面的实际情况和天气而定。当路面极为干燥时，应相对加大洒水量；雨过天晴，部分路段仍然潮湿时，则应相对减少洒水量。若路面泥土或沙石过多，需待环卫扫路车或工人打扫完毕后，再进行洒水作业。
许多初次购买洒水车的用户，总是认为洒水车洒水量越大越好，这种想法是不正确的。洒水车洒水量越大，被洒水的路面距离就会越短，导致洒水车水罐的加水次数增多，往返车程相对的油耗随之增加，其经济效益就会下降。
其次，洒水量太大，容易造成低洼路段积水，部分水会顺着路流入下水道中，形成水资源和经济上的双重浪费，碰到地面泥土过多时，则很容易形成泥泞状态，造成更多地面的二次污染，严重的甚至有堵塞下水道的可能。待地面干燥后，更容易形成大面积的尘土飞扬和污染，给环卫的扫路工人带来不便。综合上述，洒水车洒水量大了反而不好，而洒水量小了又起不到明显作用。所以，要结合当地实际应用状况来制订科学又合理的技术指标，以获得实用又经济的洒水车流量。
另外洒水车在使用过程中也需要注意以下操作细节：洒水车对水源的要求当洒水车(东风或解放)利用河沟、池塘作为水源时，注意吸水管端部全部没入水中。为避免吸入石块或较多的泥沙、漂杂物，吸水管端部一般设有过滤装置，吸水时严禁将过滤装置拆下。如果水源较浅，需要事先将吸水处挖深一些，以保证不含有杂物及不进空气。不同洒水车的水泵对水源的要求是有区别的，清水泵要求水中不能有杂质，浊水泵则要求水中不能有石块和过多的泥沙。
洒水车加引水离心式水泵每次吸水前，必须向水泵内加入一定量的引水，加完后必须关闭加水口。自吸式水泵第一次使用时，需要加引水，以后则不必再加引水。
洒水车进水管必需要真空吸水时进水管系统必须保持一定的真空度,才能将水吸入箱内。进水管系统务必要密封可靠，软管不能破损，硬管不能有裂纹，否则将产生漏气现象，也就造成吸不上水的情况。
洒水车停车挂档洒水车无论是在吸水前，还是在洒水前，取力装置挂档都必须在停车时进行。
洒水车冬季放水冬季来临前，洒水车应将水泵和水管内的水放空，以防冻裂。我国北方一般严冬不再施工，故在施工结束后，就立即将水泵及水管内的水排空，以防后患。
