Interrupted tone level of noise and high rotating speed under high frequency strike note level of noise can ensure that in a rational noise level, so that it is guaranteed that whole
The noise level of gas compressor.
As shown in Figure 8 and Figure 9, when the ratio of L1/L is limited in 0.25 and 0.5 interval range, compression can be effectively improved
Under machine interrupted tone at the low rotational speed and high rotating speed, high frequency strike note can ensure that in a rational noise level, so that it is guaranteed that whole
The noise level of gas compressor.
In addition, lift height h0 of lift stopper 3 need to be defined designing it is ensured that in certain scope can simultaneously and
Turn round and look at noise and performance reliability.As shown in Figure 10 in the present embodiment, to lift height on the premise of ensureing compressor performance
H0 carries out reasonable selection.When T*b0 is equal to 0.915, limit lift height h0 between 2.5 to 3.47, when T*b0 is equal to 1.27
When, limit lift height h0 between 1.8 to 2.5, limit the height value of lift stopper 3 in this block design, can preferably protect
Card compressor performance level and reliability, can take into account noise level, including under the interrupted tone under the slow-speed of revolution and high rotating speed simultaneously
