Description

Technical Field

[0001] This invention belongs to the field of compression equipment technology, and relates to a compressor, and more particularly to a screw compressor and its silencing device. Background Technology

[0002] Currently, exhaust silencers widely used in screw compressors are usually installed in a fixed manner. However, this fixed installation method has the following drawbacks: thermal expansion occurs during the hot operation of the compressor unit. If the assembly clearance is not accurately reserved, large stresses are often generated, which can cause the compressor body to deform and thus damage the compressor, making the equipment installation more difficult.

[0003] In addition, another installation method is to use a vertical spring support. In this method, due to the spring travel, the support height is relatively high, which requires the screw compressor to be installed at a higher height, making it inconvenient for the compressor's vibration control and maintenance.

[0004] In view of this, there is an urgent need to design a new method for supporting the exhaust muffler of screw compressors in order to overcome the aforementioned defects in the existing exhaust muffler supports for screw compressors. Summary of the Invention

[0045] The position adjustment device 2 includes at least one position adjustment mechanism, and each position adjustment mechanism is connected to the silencing device; the position adjustment mechanism includes a connecting mechanism 202, a supporting mechanism 201, a first fixing mechanism 203, an elastic mechanism 204, a second fixing mechanism 206, a sliding inclined pad 208, a fixed inclined pad 209, and a third fixing mechanism.

[0046] The connecting mechanism 202 can be fixed to the supporting mechanism 201 by the first fixing mechanism 203. The supporting mechanism 201 is disposed on the base 1, and the fixing inclined pad 208 is fixedly disposed on the base 1. The fixing inclined pad 209 has a first slope, and the sliding inclined pad 208 has a second slope. The second slope of the sliding inclined pad 208 is configured to cooperate with the first slope of the fixing inclined pad 209, and the sliding inclined pad 208 can slide along the first slope of the fixing inclined pad 209. One end of the connecting mechanism 202 is provided with a longitudinal guide mechanism 207 (such as a T-shaped sliding pin). The sliding inclined pad 208 is provided with a longitudinally arranged groove, which serves as a longitudinal slide of the longitudinal guide mechanism (of course, the slide can also be in other ways). The cross-section of the groove can be T-shaped, corresponding to the shape of the T-shaped sliding pin, so that the T-shaped sliding pin can slide exactly in the groove. The elastic mechanism 204 is nested within the connecting mechanism 202. The first end of the elastic mechanism 204 is fixed to the second fixing mechanism 206, and the second end of the elastic mechanism 204 is connected to the supporting mechanism 201. The third fixing mechanism 211 is based on the sliding inclined pad 208 and is used to fix the silencing device 3 so that the silencing device 3 can move along with the sliding inclined pad 208.

[0047] In one embodiment of the present invention, the connecting mechanism 202 can be a screw, which can be fixed to the support mechanism 201 by the first fixing mechanism 203. The support mechanism 201 can include a base plate (the base plate can be fixedly disposed on the base 1), and a sliding inclined washer 208 and a fixing inclined washer 209 are provided on the base plate; a limiting mechanism is provided on the first side of the base plate, which can better fix the fixing inclined washer 209 to the base plate (that is, the fixing inclined washer 209 can be fixedly disposed on the base by the base plate).

[0049] In one application scenario of this invention, the laterally adjustable spring support for the screw compressor exhaust muffler is fixed to the base by welding or bolting. Four sets of supports are fixed to the bottom of the exhaust muffler saddle, with the two supports near the muffler inlet positioned oriented in the direction of the muffler cylinder diameter, and the two supports near the muffler exhaust outlet positioned oriented in the direction of the muffler cylinder axis. The screw compressor exhaust outlet and the exhaust muffler inlet are connected by a flange. A radial oblong hole is opened on the saddle near the muffler inlet, and an axial oblong hole is opened on the saddle near the muffler exhaust outlet.

[0050] The spring support includes: a base plate, a screw, a locking nut, a spring, a spring washer cap, an adjusting nut, a T-shaped pin, a sliding wedge shim, a fixed wedge shim, a stud, and a nut. In use, the spring support is first placed in the corresponding base position and orientation of the muffler mounting hole. Then, the muffler is placed on the spring support. The spring stroke is changed by moving the adjusting nut on the screw, thereby changing the spring force. The T-shaped pin drives the sliding wedge shim to move, thus allowing the muffler to move along the height direction. The fixed wedge shim has a concave groove in its center, and the sliding wedge shim has a convex groove in its center. The fixed and sliding wedge shims are positioned perpendicular to the spring direction by their concave and convex structures.

[0051] In summary, the screw compressor and its silencing device proposed in this invention can improve the ease of installation of the compressor silencing device and can eliminate installation stress caused by human factors as much as possible.
