Dress balanced type air wave refrigerating device overall structure aspect, embedded top is guaranteeing to realize on the basis of production function, mainly considers rational in infrastructure feasiblely, and mounting or dismounting are convenient.The mounting or dismounting of machine intimate part are all carried out through port above, avoided facing upward head and upwards strike the difficulty of dress bearing and inconvenient in the time that organism bottom is installed bearing.When installation, first outside body, axle and nozzle are assembled together, then, on main body, bearing block, bearing and seal below nozzle are laid successively and fixed, then the main shaft and the nozzle etc. that have been assembled together are packed in machine in the lump, this axle all has and coordinates with bearing and the seal of bottom, and the black box on top is then installed.So, gas wave machine mounting or dismounting are convenient, and can ensure matching requirements.
In order to reach the requirement of installing from top completely, body is divided into two parts.On main body, be provided with air inlet pipe, blast pipe and circumferentially uniform tens of borings to more or less a hundred connection adopter of ring, need and processing consideration easily for structure, main shaft also can form by two sections: one section is part hollow shaft, part solid shafting; Another section is hollow shaft.Two sections of axles are by being weldingly connected.Gas at normal temperature first enters hollow shaft again through reducing pipeline section, then enters by hollow shaft the other end jet nozzle coordinating with it, injects along in one week equally distributed receiving tube of body, completes the overall process of gas wave refrigerating.Hollow shaft section is positioned at the lower semisection of machine, for gases at high pressure are incorporated into the other end, topmost, Gu punching in the middle of main shaft upper semisection solid section.Unique consumable accessory bearing of changing for convenience this machine, machine two ends respectively arrange a bearing block, and main feature is that all part mounting or dismounting are all to complete from the top of machine.Underpart is integrally closed form after welding enterprising tracheae, non-dismountable, internals is installed and must implements operation by top, and this has just been avoided a collection of parts such as a need of work dismounting admission line and flange bottom end cover such as replacing bearing completely.
By long-term known to the mechanism research of air wave refrigerating device: the gas blending after the gas at normal temperature of import is freezed with outlet can significantly reduce the refrigerating efficiency of air wave refrigerating device, and this is definitely that we do not wish the result of seeing.Thereby between inlet tube and outlet, the sealing in region is essential, and choosing of seal form is extremely important and crucial, because the impact of the good and bad refrigerating efficiency on air wave refrigerating device of sealing is very big, if think farthest to improve the refrigerating efficiency of machine, wherein one of effective method is to select a kind of reliable and effective sealing the most.Labyrinth seal is simple in structure compared with other seal form, is easy to processing, and can reach the requirement of production process to sealing.The form kind of labyrinth seal is a lot, wherein main Types has dividing of radial labyrinth and axial labyrinth, the general institute of radial labyrinth takes up space relatively large, often need the many covers of many groups dynamic and static ring sealing assembly to coordinate, remove and install cumbersome, therefore,, according to the requirement of this refrigeration machine structure and performance, primary seal is that the axial labyrinth seal of employing is main.
Exactly because aforesaid reason, the structure of main shaft is very unique, labyrinth seal rotating ring and axle that crucial sealing function is played in machine bottom are designed to one, by one of the two advantage uniting two into one of main shaft and moving sealing ring be reduced together with important cooperation, improve the accuracy of manufacture, do with this rotating ring axle the stationary ring coordinating and make discrete item, be seated on step and be mated, and using it as positioning datum.Cloth tooth between dynamic and static ring is to be main vertically, and combine how radially-arranged detouring, can ensure under the prerequisite of the sealing number of teeth like this, greatly shorten axial length, take full advantage of space, shortened axial length and body length, not only saved raw material, also make support interval shorten, the stressed of axle improves.Also has a very important aspect, because the pressure working condition of the air wave refrigerating device in production and application process is usually very high, such as admission pressure is common operating mode more than 1MPa, sometimes inlet and outlet pressure reduction is up to tens to tens MPa, and high like this pressure reduction will make the bearing supporting as running bear high axial force.On the axle itself producing for this large pressure reduction just and axle thereof, part is subject to king-sized axial force problem, take the position that enters intermediate noxzzle place in the gases at high pressure warp beam of hollow shaft to be incorporated in the axle of opposite side above nozzle, again by reverse pumping foldback in the middle of one side direction of top, the gases at high pressure of transference machine import same pressure via with the almost identical number of teeth of lower semisection axle and one group of dynamic and static ring sealing assembly of the same area, by after gas pressure be decremented to nozzle near machine exit pressure identical, the pressure after by labyrinth seal is identical with gas on lower semisection axle, also under same diameter same size, arrange the sealing number of teeth of equal number.So far from pressure-acting substantially having offset with joint efforts on main shaft on both sides.Can greatly alleviate shaft strength, reduce maintain and replace number of times, improve the service life of refrigeration machine.At the center taking adopter on nozzle and body, as line of demarcation, the moving sealing ring that plays balancing axial thrust effect at opposite side adopts the form of movable part, and stationary seal ring adopts the form of axle sleeve, and therefore easy accessibility, also can avoid assembling time damages broach.Aspect cloth tooth, all adopt axial cloth tooth, the chance number of teeth is crossed and is radially arranged at most the axial labyrinth seal of multiple tracks, this also belongs to axial combination labyrinth seal radially and uses, this form can make moving sealing ring and stationary ring convenient processing and maintenance, be easy to processing, especially easy installation and removal, and can meet seal request.
Nozzle is one of critical component of air wave refrigerating device.The nozzle of the machine is made up of two parts: a part is the nozzle body that is processed with inner flow passage, is positioned at the part of bottom and the tubular capping of another part is positioned at top, and they are to be set on main shaft, compress by large round nut.Between capping and nozzle, axle, with seal with O ring, prevent gas leakage.Also has a kind of nozzle arrangements of form: to be that two parts are chimeric form swivel nozzle, can accomplish like this better tightness, prevents that internal gas is to external leakage.Inlay engagement position for two and be selected in jet hole place, upper and lower two of its area size respectively accounts for a part.So both be convenient to the processing finishing that nozzle interior runner, throat and outer edge surface etc. are located, and the sealed against leakage between two parts had been had to good action effect.In addition, because the gas wave machine nozzle diameter size of this kind of structure is larger, and location comparison is near the opening end of body, can on body, process the square transition flow road junction of matching with jet hole by manual mode, therefore installs the design of lining additional without employing.
Embedded top dress balanced type air wave refrigerating device both can be in the situation that having driven without any need for additionaling power, complete use device is imported and exported gas differential pressure and is made machine rotation, can also drive by installing motor additional the rotating speed of refrigeration machine running or assistant regulating and controlling machine, avoid changing due to service condition and operating mode, cause the reduction of refrigerating efficiency, therefore can work efficiently under lower rotating speed.
If provide part to drive power with motor, because the booster action of additional motor is very important for efficiency, can guarantee that by regulation and control rotating speed the refrigerating efficiency of refrigeration machine is stable.And connecting between external motor and machine inner main axis is very crucial, internal gas, especially flammable explosive gas absolutely not must leak, in the past cannot head it off, therefore generally do not design connection motor, even if extremely need, also only limit to low pressure occasion.Because can only rely on common static seal, of long duration be easy to leak.The machine has adopted a kind of magnetic force coupling arrangement, has solved sealing problem herein completely.It is to have utilized permanent magnet magnetic strong and the feature such as can shape, an outer magnetic cylinder is manufactured in the one end connecting with motor, once this machine be thoroughly avoid vertical electric arbor to channel bit causing rotating outer magnetic cylinder disjunctor minor axis and static middle spacer sleeve frictional heat on fire, therefore do not connect straight motor on minor axis, but connection belt pulley, motor carrys out drive shaft by band transmission and rotates.Work one interior magnetic cylinder is joined in one end on body inner main axis, and install a fixing spacer is set between inside and outside magnetic cylinder, effect is to prevent from pressing in machine external leakage, and inside and outside magnetic cylinder is to be respectively processed into the extremely staggered and encapsulation by N, S after many magnetic stripes by permanent magnet.When the work of this machine, motor rotates with together with outer magnetic cylinder on it, the effect of inhaling by magnetic picture, magnetic cylinder and main shaft and then drive nozzle synchronous rotary in driving.In addition at nozzle interior runner to jet orifice, also have the circumferential all receiving tube pores of main body pressed on ring all by there being certain drift angle design, object is to make the tumbler such as nozzle, main shaft produce certain deflection torque, is used for assisting motor to reduce load.
