Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
As shown in Fig. 2, the present embodiment straight-line compressor, including shell 1 and the mover being arranged in the shell 1
2, stator 3, cylinder 4, piston 5, spring bearer plate 7, aspiration column 6 and oil pump 8,1 bottom of shell are stored with lubricating oil, the oil
Main oil feed line 801 and preheating oil feed line 802 are connected on pump 8, the main oil feed line 801 is used to supply to the cylinder 4
To lubricating oil, the preheating oil feed line 802 is used to supply lubricating oil to the surface of the aspiration column 6.
Specifically, the increase of oil pump 8 in the present embodiment straight-line compressor has preheating oil feed line 802, actually make
With in the process, oil pump 8 is supplied outside lubricating oil except through main oil feed line 801 to cylinder 4, also passes through preheating oil feed line 802
To the surface transport lubricating oil of aspiration column 6, since cylinder 4 and piston 5 will generate heat in the process of running, so that flowing through
The lubricating oil of cylinder 4 obtains heat and is heated, and finally, so that the lubricating oil bulk temperature of 1 bottom of shell increases, and preheats fuel feeding
Pipeline 802 delivers lubricating oil to the surface of aspiration column 6, and lubricating oil will heat aspiration column 6, so that by air-breathing
The refrigerant of 6 sucking of cylinder can be pre-heated, and after the refrigerant being drawn into aspiration column 6 is heated, it will thoroughly effectively eliminate liquid
The refrigerant of state improves the use reliability of the present embodiment straight-line compressor effectively to avoid the phenomenon that generating liquid hammer.Its
In, oil feed line 802 is preheated for the ease of installation, is offered through-hole (unmarked) on the spring bearer plate 7, the preheating fuel feeding
Pipeline 802 is inserted in the through hole, and the oil outlet of the preheating oil feed line 802 is located at the top of the aspiration column 6.
Further, multiple oil storage tanks 61 for being used to store lubricating oil are formed on the outer wall of the aspiration column 6, specifically,
It will be flowed into oil storage tank 61 by preheating oil feed line 802 to the surface transport lubricating oil of aspiration column 6, so as to slow down profit
Lubricating oil is flowed down from aspiration column 6, the effective heat exchanger time extended between lubricating oil and aspiration column 6, and increases the two
Between heat exchange area, so as to more rapidly and effectively be heated to the refrigerant being drawn into aspiration column 6.Wherein, it stores up
Oil groove 61 is annular groove, and multiple annular grooves 61 are interconnected by through slot 62, and each oil storage tank 61 is interconnected, can
So that lubrication oil distribution is more uniform.In addition, offering sliding support hole (not shown) on mover 2, the aspiration column 6 is inserted in
In the sliding support hole, mover 2 is supported by aspiration column 6, and the annular groove 61 that 6 surface of aspiration column is formed will reduce with
Contact area between mover 2, to effectively reduce the loss that friction generates.Preferably, it is offered on the inner wall of aspiration column 6
Multiple silencing grooves 63 after refrigerant is inhaled into aspiration column 6, make caliber ruler since the inner wall of aspiration column 6 forms silencing groove 63
Very little unexpected increase, the variation of interior caliber can reduce the noise of sucking refrigerant, play the role of muffler, therefore not need additional
Increase the components such as muffler, reduces whole manufacturing cost.
Further, in order to improve fuel feeding efficiency, the oil pump 8 includes oil cylinder 81 and oil piston 82；The oil piston
82 one end is formed with left-hand thread slot 821, and the other end is formed with right-hand thread slot 822, and the oil piston 82 is slidably arranged in
