Abstract

The invention discloses a reversing diaphragm pumping device for an absorption refrigerating system. The device is arranged between an absorber and a generator of the absorption refrigerating system, and comprises a diaphragm machine, a first reversing valve, a second reversing valve, a third reversing valve, a low-pressure conveying pump and a control system; and the diaphragm machine includes a cavity, and a diaphragm arranged in the cavity and capable of moving up and down. Compared with the prior art, the electromagnetic reversing diaphragm pumping device for the absorption refrigerating system, provided with the invention, achieves the separate conveying purpose of high / low-pressure solution through matching the reversing valves with the diaphragm machine for use, largely reduces the energy loss caused by high pressure difference in the solution conveying process, overcomes such defects as easy cavitation and easy leakage caused by a traditional high-pressure pump, and enhances the total system stability when saving the energy consumption.

Description

technical field [0001] The invention relates to the technical field of absorption refrigeration systems, in particular to a reversing diaphragm pumping device for an absorption refrigeration system. Background technique [0002] At present, the absorption refrigeration system usually uses a high-pressure centrifugal pump or a diaphragm pump to transmit the working medium solution from the low-pressure side to the high-pressure side, which requires a large power to overcome the pressure difference to do work, and is prone to cavitation and cause the pump to fail to work normally. Running for a long time will produce obvious wear and tear, solution leakage and other problems. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide an electromagnetic reversing diaphragm pumping device for an absorption refrigeration system to solve the problem that high-pressure centrifugal pumps or diaphragm pumps ...
