Description

The scroll compressor that send the lubricants capacity device is given in control

Technical field

The utility model belongs to scroll compressor, and the scroll compressor that send the lubricants capacity device is given in particularly a kind of control.

Background technique

As everyone knows, the structure of scroll compressor comprises housing, fixed scroll, activity scroll, cross ring part and bent axle, in shell, be equiped with the fixed scroll of spirality scroll wrap, the activity scroll that in fixed scroll, cooperates the spirality scroll wrap of packing into, a plurality of scroll wrap of fixed scroll and a plurality of scroll wrap of activity scroll are by the formation compression chamber of working in coordination, activity scroll and fixed scroll by the driven by motor crank-driven are done reciprocal translation, thereby form the continuous motion of the refrigeration agent that sucks, compresses, spues; In order to prevent that the side of activity scroll generation rotation in fixed scroll also is equipped with the cross ring part.At present, the refrigerator oil lubricated and sealing usefulness between fixed scroll in the compressor and activity scroll is by the air-breathing compression chamber that enters, and compressed chamber links to each other with compressor bottom lubricating oil tank by the oilhole in the bent axle; The oil mass passed through of shut-in time control oil channel by the control oilhole, and the switching of oilhole generally is to utilize the surface of contact of fixed scroll member and movable scroll element to realize, the oil mass in the compression chamber how much determined sealing effect in the compression process and the friction factor that slides mutually.But because the existence of tilting moment in the compression process, the state that breaks away from fixed scroll member can appear in movable vortex, oilhole is opened and is increased flow of lubrication, in general, the many more sealing effects of oil mass are good more, frictional loss is also more little, still, and when oil mass is too much, can reduce effective delivery space of compressor, increase power input to machine, so, must the interior oily circulating load of appropriate control compression chamber.Simultaneously, also because the uncertainty of system, the oil mass of getting back to air aspiration cavity is unsettled, and for example when compressor operating during in less air displacement operating mode, the refrigeration system recirculating oil quantity also can diminish thereupon.Therefore, this suddenly big or suddenly small lubricants capacity of giving just can not be guaranteed the proper functioning of compressor.

Summary of the invention

The utility model is intended to the shortcoming and defect part that exists in above-mentioned technology, and provide not only reasonable in design, compact structure, both controlled the suitable oil mass of giving by throttling, guarantee the proper functioning of compressor again, and have stable and reliable operation, low cost, be convenient to install, the scroll compressor that send the lubricants capacity device is given in handling safety and a kind of very easily control of use.

The purpose of this utility model is to adopt following technological scheme to realize: the scroll compressor that send the lubricants capacity device is given in described control, comprise housing, fixed scroll, the activity scroll, cross ring part and bent axle, it is characterized in that: install oil-flow control apparatus on the activity scroll in housing, described oil-flow control apparatus is by horizontal oilhole, or the piston of the stopper rod of throttling or throttling, apical pore and bottom outlet are formed, processing one horizontal oilhole in the heel plate face of activity scroll one side, laterally be tightly connected or the stopper rod of cellular type throttling in the oilhole earlier, or the piston of capillary type throttling, use the plug seal orifice then; In the heel plate face at horizontal oilhole top processing or with stopper rod or the apical pore that is connected with piston; The bottom outlet that processing is connected with oilhole in the bent axle in the heel plate face of horizontal oilhole the other end bottom surface.

The stopper rod of described cellular type throttling or employing metallic material or employing nonmetallic material are made; Or be tightly connected or be connected in the horizontal oilhole with thread seal with interference, have the throttling duct in the stopper rod.

The piston of described capillary type throttling or form by piston body and capillary tube, or form by piston body, sealing gasket and capillary tube, piston or adopt metallic material or adopt nonmetallic material to make wherein, or be tightly connected or be connected in the horizontal oilhole with thread seal with interference.

The utility model principle and operation are described below: because the utility model is processed a horizontal oilhole in heel plate face, and after aperture one end seals with plug, laterally packing into or the stopper rod of throttling or the piston of throttling in the oilhole, and be connected with apical pore in the activity scroll heel plate face, apical pore is positioned at air aspiration cavity or is positioned on the slip surface of fixed scroll, movable vortex when compressor operation; Laterally the bottom outlet in the heel plate face of the oilhole the other end is connected with oilhole in the bent axle; And oilhole and compressor bottom lubricating oil tank is connected in the bent axle, when the lubricating oil pressure in the crankshaft oil hole during greater than the pressure in the compression chamber, the lubricant oil piston flow entrance pressure that just bottom outlet in oilhole, the heel plate face enters the stopper rod of lateral oil aperture throttling or throttling in the bent axle chamber that contracts, thus realized the motion between fixed scroll member and movable scroll element lubricated.In order to provide suitable for sending lubricants capacity, in the piston of the stopper rod of throttling or throttling, be provided with the throttling pore of determining size as calculated.Ordinary circumstance, the compressor unit time refrigerant that spues carries oil mass and is less than 5% of the coolant quantity that spues.Safe and reliable, low-cost and advantage easy for installation that this throttle structure has.

Combine the above technological scheme of being taked, realize the purpose of this utility model.

Compared with prior art, the utility model is not only reasonable in design, compact structure, both controlled the suitable oil mass of giving, and guaranteed the proper functioning of compressor again, and have stable and reliable operation by throttling, low cost is convenient to install, handling safety and use advantages such as very convenient.
