â– . The inlet pipe must be vacuum pan
The water inlet pipe system must maintain a certain degree of vacuum before it can suck water into the tank. The inlet pipe system must be sealed reliably, the hose can not be damaged, the hard pipe can not have cracks, otherwise it will have a phenomenon of air leakage, which will result in the situation that it cannot suck water.
â– . Parking gear
Before the water sprinkling vehicle is water-absorbing, or before watering, the power take-off device must be stopped while parking. The correct method is to stop the car first, step on the clutch pedal and wait for the main gearbox shaft to completely stop. Hanging gear. If it is to prepare traffic sprinkler (usually low-speed water-sprinkling), it should hang the gear 2 of the main gearbox before stopping, then hang the power-shift gear, and then slowly lift the clutch pedal. When the sprinkler is walking, turn on the sprinkler switch. Start watering. If the power-up gear is operated by air, the barometer must be observed and the pressure must reach the specified pressure value before the gear can be started. If you ignore the parking gear, it can cause damage to the gear or housing.
â– Drainage in winter.
Before the advent of winter, the water of the pump and the water pipe should be vented to prevent freezing. In northern China, where the winter is generally no longer under construction, the water in the pump and the water pipe should be drained immediately after the completion of construction to prevent future problems.
â– . Watering precautions
The front sprinkler of the sprinkler is located at a low level, close to the ground, and the spray pressure is high, which can be used to flush the road surface. The location of the rear nozzles is relatively high, generally one is installed on the left and right sides, and the watering surface is wider, which is used for watering highway construction. When using the post-spray, the front nozzle should be closed. When using the adjustable nozzle, the width of the sprinkling can be adjusted as needed. The wider the sprinkling width, the less overlap in the middle and the more uniform the sprinkling density. From the sprinkler price manufacturers introduction.
