Embodiment Construction
[0010] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0011] Such as figure 1 As shown, a crank connecting rod moving part of a diaphragm gas compressor includes a crankshaft 6, a balance iron 1, a connecting rod composed of a main connecting rod 7, a first bolt 4, a main connecting rod head 3 and a main connecting rod nut 2. The rod assembly is composed of a crosshead 8, a hollow pin shaft 9 and a circlip 10, a crosshead spacer 11, a crosshead pressure ring 12, a piston rod 14 and a second bolt 13. The main connecting rod assembly is rigidly connected by the main connecting rod 7 and the main connecting rod head 3 through the first bolt and the main connecting rod nut. The hollow pin shaft 9 is arranged in the inner pin hole of the crosshead 8 , and the axial positioning of the pin shaft is realized by the elastic retaining ring 10 . On the crankshaft 6 , there is a balance iron 1 fixedly connected by a first...

The invention discloses a crank connecting rod moving part of a diaphragm-type gas compressor. The crank connecting rod moving part comprises a crankshaft, balance iron, a first bolt, connecting rod assemblies, a cross head assembly, a cross head spacer ring, a cross head pressing plate, a piston rod and a second bolt; the balance iron is arranged on the crankshaft and fixed through the first bolt; the two connecting rod assemblies are arranged on an eccentric shaft of the crankshaft, and the other ends of the connecting rod assemblies are connected with the cross head assembly; the end face of the cross head assembly is provided with the cross head spacer ring, and the piston rod is connected to the cross head assembly in a rigid mode through the cross head pressing plate by using bolts;and an outer circle face of the other end of the piston rod is provided with seven piston rings. The crank connecting rod moving part has the advantages that the crankshaft of the crank connecting rodmoving part is provided with a balance body, the eccentric shaft of the crankshaft is long and can accommodate two or more connecting rods, the machining technology is simplified, and good dynamic balance performance is achieved.
Description
technical field [0001] The invention relates to the field of a diaphragm gas compressor, in particular to a crank connecting rod moving part of a diaphragm gas compressor. Background technique [0002] Diaphragm compressor, as a positive displacement compressor, has two advantages of large compression ratio and good sealing performance, so it is widely used in compressing and transporting various high-purity gases, precious and rare gases, toxic and harmful gases and corrosive gases. Gas and other special gases. The crank connecting rod movement mechanism is the core component of the diaphragm compressor, and its performance is directly related to the effect of gas compression. At present, the crankshaft of the crank connecting rod moving part mostly adopts integral type, and the processing technology is complicated. Contents of the invention [0003] The invention designs a combined diaphragm crank connecting rod moving part. [0004] The technical solution adopted by ...
