Since the suction hose is always immersed in the liquid surface, the air in the tank is sucked, and it becomes thinner and thinner because it is not replenished, so that the pressure in the tank is lower than atmospheric pressure, and the manure is used under atmospheric pressure. , through the suction hose into the tank. Or because the siphon is close to the bottom of the tank, when the air is continuously discharged into the manure tank, it is compressed because it has no way out, so that the pressure inside the tank is higher than the atmospheric pressure, and the fecal liquid is discharged by the siphon and the suction hose under the action of compressed air. Outside the can.
The suction truck has the characteristics of high suction efficiency, self-priming, self-discharging and direct irrigation. Pumping manure tank time: ≤ 5min, suction stroke: ≥ 8m. According to the characteristics of long service life, fast working speed, easy operation and convenient transportation.
