Is the sprinkling of the sprinkler as large as possible?
In the process of purchasing watering vehicles and users, users always hope that the water volume of the sprinklers should be larger, but in practical applications, the idle watering distance is short, the frequency of water addition is increased, and the fuel consumption of idle driving and returning operations is increased. Increased, poor socioeconomic performance.
The main role of sprinkler operations is to reduce heat, cool dust, and clean air. If the amount of water sprayed is too large, partial water will accumulate due to the unevenness of the ground . A part of the water will flow along the road into the sewer, causing water resources and economical waste. If there is much mud on the ground, muddy mud will easily form. Due to the adhesive tape of the vehicle tires, As a result of the extension of ground pollution, after the ground is dry, a larger area of ​​dust is formed and polluted.
The resulting topic is that the wine operation should be carried out after the floor has been cleaned, and if the heavily polluted ground is sprinkling water, it is more difficult to clean, and the amount of water sprayed is not good.
(The sprinklers manufactured by Cheng Li can freely adjust the amount of water. In addition, the high-pressure device of Cheng Li's sprinkler can clean the front of the road and sprinkle it with water after spraying. This will not allow water and miscellaneous As things get mixed up, sanitation workers only need to clean the two sides of the road.)
2 Quantitative analysis of watering volume
In view of the above, the sprinkling of water by the sprinkler is not good, and the small amount of sprinkling does not have a significant effect.
So, how to determine the practical and economic sprinkler sprinkler? The Dongfeng EQ1092 (or EQ1092F19DJ ) type 5t sprinkler truck is used for calculation and analysis.
Performance parameters:
Engine speed range ne 1200 - 3000 r / min
Transmission speed ratio ik
One file i1 7.31
Second gear i2 4.31
Third gear i3 2.45
Power take-off ratio iT l.373
Pump
Rated speed nP 1450 r / min
Flow Q 60 m3 / h
Head H 60 m
Shaft power N 16 kw
Calculated according to the pump rated speed:
Engine speed n 1991 r / min
First gear speed Y1 7.22 km / h
Second gear speed Y2 12.24 km / h
Third gear speed Y3 21.53 km / h
Technical requirements sprinkler running speed is 5 - 20km / h, and in practice are l - 3 with the job files, it does not count the water under high-speed running of wine.
Under the rated pump speed, full load 5t , sprinkler operation time t :
t=5min
