Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figure 2, the present embodiment straight-line compressor, including shell 1 and be arranged on the mover 2 in described shell 1, stator 3, cylinder 4, piston 5, spring bearer plate 7, aspiration column 6 and oil pump 8, bottom described shell 1, storage has lubricating oil, connect on described oil pump 8 and have main oil feed line 801 and preheating oil feed line 802, described main oil feed line 801 is for supplying lubricating oil to described cylinder 4, and described preheating oil feed line 802 for supplying lubricating oil to the surface of described aspiration column 6.
nullSpecifically，Oil pump 8 in the present embodiment straight-line compressor increases preheating oil feed line 802，In actual use，Oil pump 8 except by main oil feed line 801 in addition to cylinder 4 supplies lubricating oil，Also by the preheating oil feed line 802 surface transport lubricating oil to aspiration column 6，Owing to cylinder 4 and piston 5 will produce heat in running，It is heated so that the lubricating oil flowing through cylinder 4 obtains heat，Finally，Lubricating oil bulk temperature bottom shell 1 is raised，And preheat oil feed line 802 and deliver lubricating oil to the surface of aspiration column 6，Aspiration column 6 will be heated by lubricating oil，So that the coolant through aspiration column 6 suction can be pre-heated，And after the coolant being drawn in aspiration column 6 is heated，To thoroughly effectively eliminate the coolant of liquid，Effectively to avoid producing the phenomenon of liquid hammer，Improve the dependability of the present embodiment straight-line compressor.Wherein, for the ease of installing preheating oil feed line 802, described spring bearer plate 7 offering through hole (unmarked), described preheating oil feed line 702 is inserted in described through hole, and the oil-out of described preheating oil feed line 702 is positioned at the top of described aspiration column 6.
Further, multiple oil storage tank 61 for storing lubricating oil it is formed with on the outer wall of described aspiration column 6, concrete, to be flowed in oil storage tank 61 to the surface transport lubricating oil of aspiration column 6 by preheating oil feed line 802, flow down from aspiration column 6 such that it is able to slow down lubricating oil, the effective heat exchanger time extended between lubricating oil and aspiration column 6, and increase heat exchange area between the two, such that it is able to more rapidly and effectively the coolant being drawn in aspiration column 6 is heated.Wherein, oil storage tank 61 is loop configuration, and multiple described cannelures 61 are interconnected by through slot 62, and each oil storage tank 61 is interconnected, it is possible to what it is such that lubricating oil is distributed is more uniform.Additionally, offering sliding support hole (not shown) on mover 2, described aspiration column 6 is inserted in described sliding support hole, and mover 2 is supported by aspiration column 6, and the contact area that the cannelure 61 that aspiration column 6 surface is formed will reduce between mover 2, thus effectively reduce fricative loss.Preferably, multiple silencing groove 63 is offered on the inwall of aspiration column 6, after coolant is inhaled in aspiration column 6, owing to the inwall of aspiration column 6 forms silencing groove 63, caliber size is increased suddenly, the change of interior caliber can reduce the noise sucking coolant, play the effect of deafener, therefore need not additionally increase the parts such as deafener, reduce overall manufacturing cost.
Further, in order to improve fuel feeding efficiency, described oil pump 8 includes oil cylinder 81 and oil piston 82；The one end of described oil piston 82 is formed with left-hand thread groove 821, the other end is formed with right-hand thread groove 822, described oil piston 82 is slidably arranged in described oil cylinder 81, the middle part of described oil cylinder 81 offers oil-in 811, the both ends of described oil cylinder 81 offer oil out port 812, and described main oil feed line 801 and described preheating oil feed line 802 connect with corresponding described oil out port 812 respectively.Concrete, the both ends of oil piston 82 are formed with the contrary left-hand thread groove 821 of hand of spiral and right-hand thread groove 822, in actual use, oil piston 82 moves back and forth in oil cylinder 81 because of the vibrations of compressor entirety, and in moving process, the lubricating oil entered into oil cylinder 81 from oil-in 811 will be injected into the end of oil cylinder 81 correspondence by left-hand thread groove 821 and right-hand thread groove 822, thus be embodied as main oil feed line 801 and supply lubricating oil with preheating oil feed line 802, oily piston 82 in oil pump 8 is in reciprocating movement, it is alternately that main oil feed line 801 supplies lubricating oil with preheating oil feed line 802, there is no idle stroke, effectively raise the efficiency of supply of lubricating oil.Wherein, the one end of oil piston 82 offers the first fuel-displaced breach 823 coordinated with described left-hand thread groove 821, and the other end of described oil piston 82 offers the second fuel-displaced breach 824 coordinated with described right-hand thread groove 822.It addition, the bottom surface of oil cylinder 81 offers described oil-in 811, described oil-in 811 is immersed in lubricating oil.
This utility model also provides for the coolant pre-heating mean of a kind of straight-line compressor, use above-mentioned straight-line compressor, coolant pre-heating mean is: the oil pump of straight-line compressor delivers lubricating oil on aspiration column, and aspiration column is heated to preheat the coolant entering in aspiration column by lubricating oil.
The straight-line compressor that this utility model provides, by increasing preheating oil feed line on oil pump, oil pump can deliver lubricating oil on aspiration column by preheating oil feed line, owing to lubricating oil in use heating temperature is higher, after lubricating oil trickles on aspiration column, aspiration column can be heated, the fully gasification so that the coolant entered in aspiration column is heated, the coolant that liquid is reduced or avoided enters into cylinder from aspiration column, by preheating aspiration column, the phenomenon that can avoid liquid hammer occurs, such that it is able to effectively improve the security reliability of straight-line compressor
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of this utility model each embodiment technical scheme.
