螺杆空压机和活塞空压机的优缺点
Advantages and disadvantages of screw air compressor and piston air compressor
1、功能方面的比较
1. Functional comparison
(一)、力平衡方面
(1) . force balance
单螺杆压缩机:螺杆承受的径向和轴向气体力可以自动平衡,星轮齿承受气体力,要求星轮齿具有足够的强度和刚度。双螺杆压缩机:螺杆转子承受较大的径向和轴向气体力,要求螺杆具有足够的强度和刚度。
Single screw compressor: the radial and axial gas forces borne by the screw can be automatically balanced, and the star gear teeth bear the gas force. It is required that the star gear teeth have sufficient strength and stiffness. The axial stiffness and radial strength of the twin-screw compressor are enough.
(二)、制造成本方面
(2) . manufacturing cost
单螺杆压缩机:螺杆和星轮轴承可选用普通轴承,制造成本较低。双螺杆压缩机:由于两螺杆转子负荷比较大,要求选用精度较高的轴承,制造成本较高。
Single screw compressor: ordinary bearings can be selected for screw and star wheel bearings, with low manufacturing cost. Twin screw compressor: due to the large load of two screw rotor, it is required to select bearings with high precision and high manufacturing cost.
