Abstract

The utility model provides a vibration damping device of an outlet line of a screw compressor and relates to a screw compressor assistant device, wherein the outlet line is arranged in a door-shaped frame, and fine tuning nuts are fixedly connected to the central positions outside two columns and a cross beam of the door-shaped frame; each fine tuning nut is connected with a fine tuning screw rod from outside to inside by the screw, and the front end of the fine tuning screw is arranged inside the door-shaped frame; isolating blocks which are consistent with the outlet line in radian are arranged in the radial direction of the periphery of the outlet line at intervals, a top plate is arranged outside each isolating block, a positioning ring is fixed outside the top plate, and the front end of each fine tuning screw is arranged in the positioning ring. The device provided by the utility model is low in manufacturing cost and strong in practicality, solves the problem that the outlet line drastically vibrates caused by gas pulsation generated in the operating period of the screw compressor and further overcomes the deficiency that when an elastic bracket of the screw compressor is used, the gas pulsation is amplified to generate an exciting force to the line so as to result in severe vibration of the line, so that the service life of the screw compressor is prolonged.

Description

Screw compressor exit pipeline vibration damping equipment

Technical field

The utility model relates to helical-lobe compressor auxiliary device, relates in particular to screw compressor exit pipeline vibration damping equipment.

Background technique

The recycle gas compressor of industry butadiene product equipment is generally twin-screw dry type compressor, Main Function is after degas system carbon four mixed gass are out pressurizeed again, a part enters extracting system and provides certain thermal source as stripping gas for system, another part returns to suction port of compressor to control compressor suction pressure, this equipment is as the nucleus equipment of butadiene product equipment, and whether its smooth running is determining whether whole device can long-term operation.Along with the development of machine-building, the technology of unit itself is very ripe, and the operating index of helical-lobe compressor itself is generally very good.But helical-lobe compressor gas that run duration produces causes outlet line and vibrates the difficult problem that violent problem is puzzlement industry always.The design of general SCREW COMPRESSOR outlet line is to adopt first support of outlet port to select elastic support, to reduce the stressed of compressor outlet, and use elastic support will certainly amplify the excitation force that gas produces pipeline, and bring out the judder of pipeline, normal operation to device causes very large harm, once leaking appears in pipeline, gently cause the local shut-down of device, when serious, can cause Fire explosion situation to occur.

Summary of the invention

The utility model is intended to for the deficiency existing in background technique, and a kind of screw compressor exit pipeline vibration damping equipment providing.

Screw compressor exit pipeline vibration damping equipment of the present utility model, that outlet line is placed in a type framework, be be all fixedly connected with fine-tuning nut on two columns of a type framework and the central position in crossbeam outside, each fine-tuning nut from outside to inside equal screw socket is connecting fine setting screw rod, and the front end of described fine setting screw rod is placed in an inside of type framework; The outer periphery of outlet line is interval with the spacing block consistent with its radian, and the outside of each spacing block is equipped with top board, and the outside of top board is fixed wtih positioning ring, and the front end of each fine setting screw rod is all placed in positioning ring.

As further improvement of the utility model, described each fine setting screw rod equal screw socket on the inside and outside both sides of door type framework connects trimming bolt back of the body cap.

Screw compressor exit pipeline vibration damping equipment of the present utility model, rational in infrastructure, production technology is not difficult, low cost of manufacture, practicability is stronger, solve the gas that helical-lobe compressor run duration produces and caused that outlet line vibrates violent problem, thereby also overcome when current helical-lobe compressor uses elastic support and can amplify gas to pipeline generation excitation force, cause the drawback of pipeline judder, the utility model can carry out meticulous adjusting to outlet line, is of value to the working life that has extended helical-lobe compressor.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

, be described further screw compressor exit pipeline vibration damping equipment of the present utility model below in conjunction with accompanying drawing 1.

Screw compressor exit pipeline vibration damping equipment of the present utility model, that outlet line 7 is placed in a type framework 1, on two columns of door type framework 1 and the central position in crossbeam outside, be all fixedly connected with fine-tuning nut 4, each fine-tuning nut 4 from outside to inside equal screw socket is connecting fine setting screw rod 2, and the front end of described fine setting screw rod 2 is placed in an inside of type framework 1; The outer periphery of outlet line 7 is interval with the spacing block consistent with its radian 8, and the outside of each spacing block 8 is equipped with top board 3, and the outside of top board 3 is fixed wtih positioning ring 5, and the front end of each fine setting screw rod 2 is all placed in positioning ring 5.

Described each fine setting screw rod 2 equal screw socket on the inside and outside both sides of door type framework 1 connects trimming bolt back of the body cap 6.

Screw compressor exit pipeline vibration damping equipment of the present utility model, the bottom welding side of the having plate of 1 two columns of described door type framework, can adopt welding, bolt according to actual conditions; Described fine setting screw rod 2 is arranged on a centre for three frames of type framework in order to play better effect, and the supporting fine-tuning nut 4 of fine setting screw rod 2 is welded on framework; Three fine-tuning nuts 4 are on the same radial section of outlet line 7.Described trimming bolt back of the body cap 6 is arranged on respectively on the fine setting screw rod 2 of an inside and outside both sides of type framework 1, and fine setting screw rod 2 is positioned, and effectively reduces outlet line 7 and vibrates and cause the loosening phenomenon of fine setting screw rod 2; Top board 3 is the moderate square iron plate of a thickness, and weldering one, than the slightly large positioning ring 5 of fine setting screw diameter, makes to finely tune screw rod 2 terminations can insert in positioning ring 5 in the middle of iron plate outside, is convenient to top board 3 and removably connects and locate with fine setting screw rod 2 terminations; Between top board 3 and outlet line 7, be placed with spacing block 8, spacing block 8 adopts heat-resisting rigid foam plate, can effectively protect pipe itself not finely tuned the injury of screw rod 2 fastening forces, while guaranteeing outlet line 7 temperature distortion, can freely stretch simultaneously.
