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.
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 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 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;
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.
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.
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.
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.
