What issues should be noted in the maintenance of asphalt insulation pumps

Asphalt insulation pump is suitable for conveying non corrosive, solid particle free, and solidifying media at room temperature. It is suitable for outdoor installation in high-altitude areas and occasions where insulation is required during the process. The medium temperature can reach 250 ℃ and the viscosity is 5-1500cst. Pumps can operate normally in environments below zero degrees and are used in industries such as road construction to transport asphalt products. The asphalt pump body is equipped with a spacer sleeve, which uses steam or thermal oil circulation to heat and insulate the pump, so it can work normally in a zero degree environment to determine the oil delivery. Choosing the correct speed allows high viscosity oil to fill the gear space, which is beneficial for transporting high viscosity oil.
