3.0.10 jet hose should be able to withstand 2 times the maximum pressure. In the 30-second water pressure seal test, there should be no cracking, peeling, or partial bulging.
3.0.11 The agitator of the sprinkler shall be capable of maintaining a uniform concentration of the chemical solution. The coefficient of variation of the chemical concentration shall not be greater than (ie, less than) 25%. The agitator should also be able to keep the agitation operation while the sprayer stops supplying liquid to the working device.
3.0.12 PTO matching should be reasonable, firm connection, reliable sealing, flexible hanging gear, and it must not be automatically disengaged or stuck.
3.0.13 Fans: Air-fed hydraulic spray fans shall have sufficient static pressure and dynamic pressure as large as possible. Fan wheel impeller and other major rotating parts need to be corrected for balance.
3.0.14 The operating device of the spray truck shall comply with the relevant provisions in QC/T29114-93 "Technical Conditions for Sprinkler Trucks".
3.0.15 The spraying vehicle with movable dust-removing and disinfecting device is allowed to rotate within 360° or freely adjust within 45° up and down according to the structural form while maintaining the working range and spray height.
3.0.16 The spray nozzle of the sprayer shall meet the relevant requirements in GB5135-85 "Performance Requirements and Test Methods for Sprinkler Systems of Automatic Sprinkler Systems".
