Sprinklers are available from 2 to 30 tons, but many people do not know how many tonnage sprinklers should be purchased. This article will give you a reference to explain.

Basic knowledge of sprinkler truck: What is the water flow of sprinkler truck? It mainly depends on the flow of the sprinkler pump on the vehicle, the number of sprinklers, and the throttle of the 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 drive shaft, and the drive shaft drives the sprinkler pump to work, so that the water in the pipe is ejected under pressure. The flow of the sprinkler pump directly affects the water flow of the sprinkler truck, and the flow of the pump can be seen from the model of the sprinkler pump. As for which type of sprinkler pump to use, it needs to be determined according to the volume of the sprinkler tank.

Sprinklers of 5 tons and below are generally equipped with: 65QZ40 / 50 self-priming sprinkler pump with a flow rate of 40 cubic meters / hour, that is: 666 liters / minute, equivalent to 11.1 liters / second; its head is 50 meters;

Sprinklers of 8 tons and above are generally equipped with: 80QZ60 / 90 self-priming sprinkler pump with a flow rate of 60 cubic meters / hour, that is: 1000 liters / minute, which is equivalent to 16.6 liters / second, and its head is 90 meters;

Some sprinkler customers also choose: 65QZ50 / 110 self-priming sprinkler pump, with a flow rate of 50 cubic meters / hour, which is 833 liters / minute, which is equivalent to 13.8 liters / second, and its head is 110 meters.

When you see it here, you may ask: Is there a problem with this flow? Isn't a 5-ton sprinkler counting a tank of water like this only for 7 or 8 minutes? !! Actually not, because the diameter of the water inlet and outlet of the pump is 65mm or 80mm (2.5 inch or 3 inch), but the sprinkler nozzle cannot be so large, so the water flow of the pump does not represent the water flow of the sprinkler unless you connect it externally Fire hoses or hoses for pumping or spraying water. Therefore, under normal circumstances, a 5-ton sprinkler can be sprinkled for 20-30 minutes at a time. The working speed of a municipal sanitation sprinkler is about 15-20km / h, and a faster one can reach 40km / h. In this way, a 5-ton sprinkler is counted. A car can only sprinkle water at a distance of about 20km.

The spray truck comes with four spray heads as standard: three-curved forward flush, rear spray, duckbill side spray, and high-pressure water cannon. Each spray head has an independent pipe ball valve to control the opening and closing of the spray head. The more sprinklers are opened, the greater the water flow, the water pressure will be dispersed, and the road washing effect will be reduced accordingly. This is why some sanitation sprinklers use only one front sprinkler for road watering. But this is a good thing for green sprinklers. Plants do not need much pressure for watering. Installing more sprinklers can alleviate the problem of excessive impact of the water flow and increase the amount of watering. Therefore, the location of the green sprinkler's high-level sprinkler is generally 2 sprinklers, and often customers will require 3-4 sprinklers, which is the reason.

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 the sprinkler is to increase the throttle. However, for sanitation road sprinklers during driving, the working speed of the sprinkler is generally limited.
