Discharge silencer fixing structure for hermetic compressor

Abstract

The invention is about a discharge silencer fixing structure of closed type compressor. The fixing wing panel perpendicular to the compressing chamber of the cylinder is on the front side of the chamber entrance. On the fixing wing panel, linkage wheel hub is arranged for fixing discharge silencer. On the front side of the compressing chamber, a valve assembly is fixed for preventing working liquid flowing into the chamber, which is fixed to a top cover with the valve assembly. In the top cover, a discharge chamber is formed, the discharge chamber is connected to the compressing chamber, transferring the working liquid discharged by compressing to the discharge silencer. The discharge chamber and the discharge silencer is connected by the discharge oil way on the fixing wing panel. The discharge oil way is arranged on the fixing wing panel slantwise. The invention as remarked above, the contact area between the valve assembly, the top cover and the cylinder is minimized, so the leakage is reduced and the cylinder is fixed to the surface stably.

Description

technical field [0001] The invention relates to a compressor in the field of mechanical engineering, in particular to a discharge silencer fixing structure of a hermetic compressor (A discharge silencer) in which a discharge silencer for reducing the discharge noise of a high-pressure compressed operating fluid is fixed on a cylinder. mounting structure forhermetic compressor). Background technique [0002] see figure 1 as shown, figure 1 It is the internal structure of the hermetic compressor of the connecting rod method in the prior art. like figure 1 As shown, the airtight container 1 formed by the upper container 1t and the lower container 1b is provided with a frame 2 inside. The frame 2 is supported inside the airtight container 1 by a spring 2S, and a stator 3 is fixed to the frame 2. The stator rotates the crankshaft 5 by electromagnetic interaction with the rotor 4 to be described below. [0003] A crankshaft 5 is provided through the center of the frame 2 . T...

Problems solved by technology

Also therefore, when the above-mentioned cylinder 6 is fixed on the frame 2, the connection positions of the screws are different, it is difficult to accurately fix the cylinder 6 on the frame 2, and it is also difficult to set it to have the same degree of contact.

[0016] Additionally, if Figure 4 and Figure 5 In the prior art shown, the metal top plate 28 is provided with the silencers 32, 34, so the size of the metal top plate 28 and the top cover 30 will increase, and the possibility of leakage will increase accordingly, and the manufacturing cost will also increase.

[0017] This shows that the discharge muffler fixing structure of the above-mentioned existing hermetic compressor still has many defects, and needs to be further improved urgently
