Asphalt heat pump failure reasons

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, but the pump flow is increased (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 overload and burn. Motor overload operation or protect the system to stop the pump ; Or to protect the system failure to burn the motor. Followed by the use of environmental factors: Asphalt heat pump for conveying non-corrosive, non-solid particles, at room temperature has a coagulable medium. Especially for outdoor installation and process alpine region Media needs insulation occasions, the media 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.
3. Low shear force: It is an ideal tool for conveying shear-sensitive and corrosive fluids.
4. Corrosion resistance: it can transport various fluids, such as organic solvents and corrosive liquids.
5. Idling and dry operation: air or gas-liquid-solid three-phase mixed transportation can also be transported.
6. Possess self-priming ability: self-priming, no need to fill the pump, no need to empty.
7. It has the function of a shut-off valve, does not siphon, has no seals, and has the functions of a shut-off valve and a check valve.
8. Two-way conveying function: reverse pumping and back-suction functions can be realized by changing the direction of the pump runner.
9. Simple maintenance: only need to replace the peristaltic pump hose, no valve and seal replacement.
Peristaltic Dosing Pumps Characteristic :
1 Clean and pollution-free: fluid only passes through and touches the Peristaltic Pump hose.
2. High precision: constant current, reproducibility of up to 0.5%, and flow can be precisely adjusted.3. Low shear force: It is an ideal tool for conveying shear-sensitive and corrosive fluids.
4. Corrosion resistance: it can transport various fluids, such as organic solvents and corrosive liquids.
5. Idling and dry operation: air or gas-liquid-solid three-phase mixed transportation can also be transported.
6. Possess self-priming ability: self-priming, no need to fill the pump, no need to empty.
7. It has the function of a shut-off valve, does not siphon, has no seals, and has the functions of a shut-off valve and a check valve.
8. Two-way conveying function: reverse pumping and back-suction functions can be realized by changing the direction of the pump runner.
9. Simple maintenance: only need to replace the peristaltic pump hose, no valve and seal replacement.
