洒水车基础知识:洒水车水流量是多少?主要取决于车辆上装载的洒水泵流量、以及喷水头的数量、还有就是洒水车发动机的油门。
Basic knowledge of sprinkler: how much is the water flow of sprinkler? It mainly depends on the flow of sprinkler pump loaded on the vehicle, the number of sprinkler heads, and the throttle of sprinkler engine.
每一台洒水车在罐体底部均安装有车载洒水泵,由车辆发动机带动取力器,取力器带动传动轴,传动轴带动洒水泵进行工作,从而使管道内的水产生压力喷射出去。洒水泵的流量直接影响到洒水车的水流量,从洒水泵的型号就可以看出水泵流量。至于使用哪一种型号的洒水泵,则需要根据洒水车罐体容积的大小而定。
Each sprinkler truck is equipped with a vehicle mounted sprinkler pump at the bottom of the tank. The vehicle engine drives the power take-off, the power take-off drives the transmission shaft, and the drive shaft drives the sprinkler pump to work, so that the water in the pipeline generates pressure to spray out. The flow of the sprinkler pump directly affects the water flow of the sprinkler truck. The pump flow can be seen from the model of the sprinkler pump. As for the use of which type of sprinkler pump, it needs to be determined according to the tank volume of the sprinkler truck.
5吨及以下洒水车一般配备的是:65QZ40/50自吸式洒水车泵,流量为40立方米/小时,即:666升/分钟,相当于11.1升/秒;其扬程为50米;
5 tons and below are generally equipped with: 65qz40 / 50 self-priming sprinkler pump, the flow rate is 40 cubic meters / hour, that is: 666 liters / minute, equivalent to 11.1 liters / second; its lift is 50 meters; the water pump has a flow rate of 40 cubic meters;
8吨及以上洒水车一般配备的是:80QZ60/90自吸式洒水车泵,流量为60立方米/小时,即:1000升/分钟,相当于16.6升/秒,其扬程90米;
8 tons and above sprinklers are generally equipped with 80qz60 / 90 self-priming sprinkler pump, the flow rate is 60 cubic meters / hour, that is: 1000 liters / minute, equivalent to 16.6 liters / second, and its lift is 90 meters;
也有部分洒水车客户选用:65QZ50/110自吸式洒水车泵,流量为50立方米/小时,即833升/分钟,相当于13.8升/秒,其扬程为110米。

There are also some sprinkler customers choose: 65qz50 / 110 self priming sprinkler pump, the flow rate is 50 m3 / h, that is 833 L / min, equivalent to 13.8 L / s, and its lift is 110 M.
看到这里你也许会问:这流量有问题吧,5吨洒水车按这样计算一罐水岂不是只能喷7、8分钟?!其实不然,因为泵的进出水口直径是65mm或80mm的(2.5寸或3寸),但洒水车喷头不可能是那么大的,所以泵的水流量并不代表洒水车的水流量,除非你外接消防水带或抽水管进行抽水或喷水。所以一般情况下,5吨洒水车加水一次能洒20-30分钟,市政环卫洒水车工作行进速度约为15-20km/h,快一点的可以达到40km/h,这样算来一辆5吨洒水车一罐水更多只能洒20km左右的距离。
If you see here, you may ask: is there a problem with the flow? 5 tons of sprinkler can only spray 7 or 8 minutes according to this calculation?! In fact, because the diameter of the inlet and outlet of the pump is 65mm or 80mm (2.5 inches or 3 inches), but the sprinkler head of the sprinkler can not be so large, so the water flow of the pump does not represent the water flow of the sprinkler, unless you are connected with a fire hose or a suction pipe to pump or spray water. Therefore, under normal circumstances, a 5-ton sprinkler can sprinkle water for 20-30 minutes at a time. The working speed of municipal sanitation sprinkler is about 15-20km / h, and the faster one can reach 40km / h. Thus, a 5-ton sprinkler can only sprinkle about 20km at most.
洒水车标配的4项喷洒头:三弯前冲、后洒、鸭嘴侧喷、高压水炮,每一个喷头均带独立的管道球阀以控制喷头的开启与关闭。洒水喷头开的越多,水流量越大,水的压力就被分散,道路冲洗效果就会相应降低,这也是有些环卫洒水车只采用一个前冲头进行道路洒水的原因。但这对于绿化洒水车来说这是一件好事,植物浇水本不需要太大的压力,多装个喷头就能缓解水流冲击力过大的问题,还能增加浇水量,可谓一举两得。所以绿化洒水车高位花洒位置一般是2个喷头,常有客户会要求装到3-4个喷头,就是这个道理。
The sprinkler truck is equipped with four sprinkler heads: three bend front flushing, rear sprinkling, duckbill side spraying and high-pressure water cannon. Each sprinkler head is equipped with an independent pipeline ball valve to control the opening and closing of the sprinkler head. The more sprinklers are turned on, the greater the water flow, the water pressure will be dispersed, and the effect of road flushing will be correspondingly reduced. This is also the reason why some sanitation sprinklers only use a front punch for road watering. However, this is a good thing for the green sprinkler. It does not need too much pressure to water plants. Installing more sprinklers can alleviate the problem of excessive water impact and increase the amount of watering. It can be said that killing two birds with one stone. Therefore, the high position of the green sprinkler is usually 2 sprinklers, and customers often ask to install 3-4 sprinklers, which is the truth.
另外,洒水车管道内水的压力越大,水流量自然也会加大。洒水车提高水压的办法就是加大油门,但对于在行驶过程中的环卫道路洒水车,其工作车速一般会有限制。
In addition, the greater the water pressure in the sprinkler pipe, the water flow will naturally increase. The way to increase the water pressure of sprinkler is to increase the throttle. However, the working speed of sprinkler on the sanitation road in the process of driving is generally limited.
