Embodiment Construction

[0024] Such as image 3 , 4 The sealing strip 3 of the scroll compressor shown has an involute shape corresponding to the movable scroll. The height H of the sealing strip 3 in the direction of the base circle axis of the involute line gradually increases from the outside to the inside along the involute line. The width B of the sealing strip in the radial direction of the base circle is equal from the outside to the inside along the involute. See Figure 5 , Along the involute line from the outside to the inside of each section of the sealing strip is a rectangle with increasing height. The upper end surface 32 of the sealing strip in the direction of the base circle axis is a plane perpendicular to the base circle axis, and the lower end surface 33 is an inclined surface.

[0025] The preparation method of the scroll compressor sealing strip is to mix the components polybenzimidazole, polyether ether ketone, carbon fiber, and molybdenum disulfide according to the weight parts...

Abstract

The invention provides a method for preparing a sealing strip of a scroll compressor. The sealing strip prepared by using the method has high strength, a small thermal expansion coefficient, a small abrasion rate and long service life. The preparation method comprises the following step of mixing the following components in parts by weight: 20-30 parts of polybenzimidazole, 40-50 parts PEEK (Polyether-Ether-Ketone), 5-10 parts of carbon fiber and 3-5 parts of molybdenum disulfide, and carrying out hot-press forming.

Description

Technical field [0001] The technology relates to a method for preparing a sealing strip of a scroll compressor. Background technique [0002] The scroll compressor belongs to the prior art, which includes moving scroll (moving scroll), fixed scroll (fixed scroll), body, anti-rotation ring, eccentric shaft and other parts. The shapes of the movable scroll and the stationary scroll are exactly the same, the vortex is in an involute shape, and the center line of the two is separated by a radius of gyration during installation, and the phase difference is 180Β°. The static scroll is fixed on the body, and an exhaust hole is provided on the outside of the scroll line. The movable scroll is driven by the eccentric shaft to make it swing around the axis of the stationary scroll. In order to prevent the rotation of the movable scroll, an anti-rotation ring is installed in the structure. The movable scroll and the static scroll are inserted into each other to form several crescent-shape...
