Asphalt heat pump selection error What are the consequences?

As we all know, in the oil pump industry, the major buyers are willing to purchase the pump products of good intentions, so that users can give buyers a good account of the boss, front-line workers can smooth operation, manufacturers and users will also establish long-term relations of cooperation , To forge a profound and cooperative friendship can be described as benefiting many people. Asphalt heat pump is no exception, buyers also want to buy to many people benefit from asphalt insulation pump, then, how to buy a reasonable asphalt insulation pump? Asphalt heat pump in the selection, what factors can be considered? Experts did a series of explanations for this, please note that the majority of buyers: 1, the spool shape and structure of the main flow characteristics according to the choice of factors such as unbalanced force to consider. 2, wear resistance When the fluid medium is a suspension containing a high concentration of abrasive particles, the valve core, the seat surface each time the closure will be severely rubbed. Therefore, the flow of the valve should be smooth, the valve's internal material to be hard. 3, Corrosion Due to the corrosive medium, to meet the regulatory function of the situation, try to choose a simple structure of the valve. 4, medium temperature, pressure When the medium temperature, high pressure and changes in the large, the valve core and seat material should be selected by the temperature, pressure changes in small valves. 5, to prevent flash and cavitation Flash and cavitation only produce liquid medium. In the actual production process, flash and cavitation not only affect the calculation of flow coefficient, but also the formation of vibration and noise, so that the valve life is shorter, so the valve should be selected to prevent flash and cavitation. In addition to the selection above need to pay attention, there are components of asphalt insulation pump pay attention to choose. First: The use of compressed air as the power source, for a variety of corrosive liquids, with particles of liquid, high viscosity, volatile, flammable, highly toxic liquids, can be smoked exhausted. Suitable for placement in a variety of special occasions, used to pump the kind of conventional pump can not suction medium. Second: Asphalt heat pump actuator with pneumatic actuators and electric actuators, respectively, type QBY pneumatic asphalt pump and DBY-type electric asphalt pump. Asphalt pump body (body) material has four kinds: plastic, aluminum, cast iron, stainless steel, respectively, according to the requirements of liquid or gas medium selection. Asphalt pump internal diaphragm is also based on different liquid media were nitrile rubber, neoprene, Viton, polyvinylidene fluoride, polyhexachlorethylene, so when ordering to specify the type of media.
