A brief introduction to the spray truck
Many cities now have water spray vehicles on the streets that were used more when trees were sprayed with pesticides. Nowadays, many cities turn sanitation sprinklers into sprayers , which solves the problem of sprinklers flooding people. Let's introduce the sprayer
Â
The sprayer is also called a spray duster. It is converted from a stereotyped automobile chassis or other special chassis. The sprayer sprays the trees to form a uniform mist. The coverage rate of the liquid is more than 50 percent, and the wind transports it. Coverage can reach 60 percent. When the asphalt road is sprayed, the sludge, skin peel, leaves, etc. on the road surface can be flushed to both sides of the road, and the humidity is uniform humidity.
For the maintenance of the sprayer vehicle, we must properly maintain and maintain it in accordance with the provisions of the vehicle manual specified by the sprayer manufacturer. During maintenance, the spray pump and spray pump must not be allowed to dry for a long period of time. For longer periods of idling, a small amount of water should be introduced into the pump. In the cold regions of the North, after each use, the liquid remaining in the spray pump, spray pump, and pipeline must be cleaned in a timely manner to prevent freezing of parts. When the sprinkling system of the sprayer's sprinkling air control system leaks, there is no way to eliminate the problem in a timely manner, and the copper tube directly extending from the air reservoir of the vehicle can be screwed down and down, so that the air path of the control system can be cut off. Then block the corresponding air hole in the air reservoir so as not to affect the normal operation of the vehicle brake system.
When not used for long spray vehicles, fuel and water and other liquids should spray the car exhausted. The sprayer should be parked in a place with ventilation, moisture, sun protection and fire-fighting facilities. When used after parking for more than one month, the sprayer shall be inspected, maintained and maintained strictly in accordance with the instructions for use. After each use in the northern regions of the country, the water release screws in the pump and pipeline should be released and the residual liquid should be drained to prevent freezing and cracking of parts. When the pressure in the air chamber of the diaphragm pump does not reach the specified value, the air cylinder is used for inflation. Watering and spraying can not be performed at the same time.
