Embodiment Construction

[0019] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0020] like figure 1 As shown, a high manganese steel balance weight of a compressor is roughly in the shape of a semicircle, and a plurality of holes 1a are opened on the high manganese steel balance weight of the compressor. It is a straight hole; the number and shape of the hole 1a can be adjusted according to the actual situation, such as a stepped hole.

[0021] A method for making a high manganese steel balance block for a compressor is carried out according to the following sequential steps. The first step is to mix alloy powder; the alloy powder is formed by mixing high manganese steel powder and a lubricant, and the weight of the lubricant is the 0.3%-0.5% of powder weight. High manganese steel powder is compose...

Abstract

The invention provides a compressor high manganese steel balancing weight and a manufacturing method thereof, and belongs to the technical field of compressors. The problem of high manufacturing costof an existing powder metallurgy high manganese steel balancing weight is solved. Alloy powder pressing molding and high temperature sintering molding are adopted in the compressor high manganese steel balancing weight, alloy powder is formed by mixing high manganese steel powder and a lubricant, and the high manganese steel powder is composed of the following chemical components of C with the weight percentage being less than or equal to 1.0%, Si with the weight percentage being less than or equal to 0.9%, Mn with the weight percentage being 15% to 21%, S with the weight percentage being lessthan or equal to 0.03%, P with the weight percentage being less than or equal to 0.06% and the balance Fe. The compressor high manganese steel balancing weight and compressor high manganese steel balancing weights produced by using the manufacturing method of the compressor high manganese steel balancing weight have the advantages of lower manufacturing cost and higher product quality, and meanwhile have the advantages of high precision of the compressor high manganese steel balancing weights and the density approaching that of a casting forming balancing weight.

Description

technical field [0001] The invention belongs to the technical field of compressors, and relates to a compressor balance weight, in particular to a compressor high manganese steel balance weight. [0002] The invention belongs to the technical field of compressors, and relates to a compressor balance weight, in particular to a manufacturing method of a compressor high manganese steel balance weight. Background technique [0003] The rotary piston compressor uses a crankshaft with an eccentric shaft to drive the piston to rotate in the cylinder. Using the arc surface at the end of the vane to contact the piston surface, the cylinder is divided into two areas for suction-compression-exhaust. When the motor rotor drives the crankshaft to rotate, due to the eccentricity of the crankshaft, there will be imbalance during operation, and the compressor will generate vibration and noise. In order to reduce the vibration and noise of the compressor, a balance weight is installed at b...
