Abstract: Diaphragm pump is the core power element of air source heat pump. Diaphragm pump plays an important role in the performance of the air source heat pump because of its flow, energy consumption and external volume. The current diaphragm pump structures are all plunger pumps. Although this traditional structure operates smoothly and has simple processing technology, it has the disadvantages of high energy consumption and large external volume, which can not meet the high index requirements of users for air source heat pumps. In view of the current problems of the diaphragm pump, the linear guide rail is applied to the pump structure through mathematical theoretical analysis and three-dimensional modeling and other research methods to replace the traditional spring cam structure and connecting rod structure. After calculation and analysis, the new structure of the diaphragm pump can save 2% of the power in the work, which is helpful to improve the energy efficiency of the air source heat pump unit. At the same time, the new structure also reduces the overall size of the diaphragm pump, The floor area of the air source heat pump unit is correspondingly reduced, which also makes it more widely used and has better practicability.
