Analysis of the failure of asphalt heat pump

Asphalt heat pump users are most eager to do at work is not a fault, then in the smooth work, the asphalt heat pump failure what is the reason? Asphalt pump insulation structure features: The pump pump with hollow sandwich, with import and export flanges, the principle of insulation is through the thermal oil, steam, hot water and other media on the transport of liquids and pumps for heating insulation and cooling. When the transmission viscosity should be used when the deceleration motor, speed motor or pulley and other transmission methods to reduce the pump speed. Repeated cycle to ensure the operation of asphalt insulation pump. All along, bitumen insulation pump in the industry plays an important role and value, but many different users use, the problems that arise are different. Asphalt heat pump failure, the first from the pump selection. Pump selection, the lift is too high election, but the actual use of the pump is to reduce head use; the other is the pump need to change the location often used; the third case is the pump flow need to be adjusted often. These three conditions above may overload the pump and affect the reliability of the pump. : The pump is safe to use when the pump is operating at the design point and less than the rated motor power. However, as the pump head decreases, the flow rate increases (as can be seen from the pump performance curve) The power also increases.When the flow rate exceeds the design point flow and reaches a certain value, the input power of bitumen heat pump may exceed the rated power of the motor and cause the motor to over load and burn out.When the motor overload operation, either the protection system action to stop the pump Rotate or protect the system to make the motor burned down, followed by the use of environmental factors: Asphalt heat pump for conveying non-corrosive, non-solid particles, solidified at room temperature medium, especially for alpine outdoor installation and process Medium needs insulation occasions, the medium temperature up to 250 ℃, the viscosity of 5 ~ 1500cst. Can also be used to transport heavy oil, asphalt, plastic, resins, detergents and so on. However, users may occasionally use asphalt insulated pumps for fire protection and emergency protection. Last but not least, consider the economics of bitumen pumps: one of the criteria for their selection, but must be based on a safe, applicable and reliable economy. Asphalt heat pump economy is not only the price of the product, but also give priority to its function and quality, as well as the cost of installing maintenance and other accessories required. More importantly, the cost of a bitumen heat pump in the entire automatic control system in the entire automatic control system and even the production line is minimal, if the attempt to cheaper and wrong early damage caused by the group is huge.
