1, asphalt insulation pump working life, this is not included in the factory test project, a type test project. In order to ensure the quality of regular manufacturers should be selected brand-name products.
2, bitumen heat pump working standard: sub-long-term work system, repeated short-term work system and short-term work system three. Conventional products are long-term work system, that coil allows long-term power work. For a long time the valve is opened only for a short time off, it is appropriate to use the normally open asphalt insulation pump. Used in short-time working system and the volume is very large, special orders can be made to reduce power consumption.
3, Asphalt heat preservation pump working frequency: When the action frequency is high, the structure should be preferred direct acting asphaltic heat preservation pump, the power is preferably exchange.
4, the reliability of asphalt pump action, strictly speaking, this test has not been formally included in China's professional standard asphalt heat pump, to ensure that the quality should be selected regular manufacturers brand-name products. In some occasions, the number of actions is not much, but the reliability requirements are very high, such as fire protection, emergency protection, must not be taken lightly. Particularly important, you should also take two double insurance.
