Abstract

The invention discloses a piston reversing pumping device for an absorption refrigerating system. The piston reversing pumping device is arranged between a generator and an absorber of the absorption refrigerating system, and comprises a device body, reversing valves, pistons and control rods; three three-way pipes and a solution cavity are arranged on the device body; the reversing valves are arranged on the three-way pipes; and the reversing valves and the pistons are connected through the control rods to realize linkage. Compared with the prior art, the piston reversing pumping device for the absorption refrigerating system drives the reversing valves through movement of the pistons to achieve the separate conveying purpose of high / low-pressure solution, 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 an absorption refrigeration system, in particular to a piston reversing 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 a piston reversing pumping device for an absorption refrigeration system to solve the problem that a high-pressure centrifugal pump or a diaphragm pump needs a large power ...
