Abstract
The invention provides an oil return structure for a piston compressor body, and relates to the field of compressor equipment. The oil return structure for the piston compressor body comprises a midbody, a crank case and a connecting drum. The crank case is connected with the midbody. The midbody is connected with the connecting drum. An oil return hole A is formed in the lower portion of the junction face of the crank case and the midbody. An oil return hole B is formed in the lower portion of the junction face of the crank case and the midbody. The oil return structure for the piston compressor body is suitable for different types of piston compressors. According to the oil return structure for the piston compressor body, lubricating oil brought out by a piston rod and a cross head can back flow to the crank case anew. The oil return structure for the piston compressor body has the following advantages that waste of the lubricating oil is reduced, much accumulated lubricating oil causing friction with a high-temperature piston rod which does reciprocating motion at a high speed is avoided, and the lubricating oil is prevented from being brought into filler, an air cylinder and the like.
Description
Technical field
The present invention relates to compressor apparatus field, particularly relate to a kind of piston compressor body oil-returning structure.
Background technique
Compressor is a kind of driven fluid machinery low-pressure gas being promoted to pressurized gas.Compressor block is made up of parts such as fuselage, middle body, middle extend necks, and it act as: 1, as location and the targeting part of driving mechanism; 2, the part of active force is born as body; 3, as cylinder bearing block and connect some accessory.Piston compressor is in the process run up, lubricant oil in packing elements and crankcase can constantly be brought in connecting cylinder and middle body by the high speed to-and-fro motion of piston rod and crosshead, make to accumulate too much lubricant oil in connecting cylinder and middle body, a lot of drawback can be brought like this:
1, too much lubricant oil accumulation causes the waste of a large amount of lubricant oil;
The piston rod friction of the lubricant oil and high speed to-and-fro motion high temperature that 2, build up to piston rod can accelerate the rotten of lubricant oil greatly;
3, rotten lubricant oil can bring filler, cylinder into along with piston rod, thus accelerates the wearing and tearing of filler, cylinder, when compressed media is the harm that inflammable gas may cause blast etc. serious.
Summary of the invention
The object of the present invention is to provide a kind of piston compressor body oil-returning structure, to solve the problems of the technologies described above.The direct perforate on body part of this structure, precise match realize the object of oil return.Compressor block oil-returning structure object of the present invention is the backflow realizing lubricant oil in connecting cylinder and middle body, eliminates lubricant oil and accumulates the drawback brought, thus provide a kind of economy, safe and reliable body oil-returning structure.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of piston compressor body oil-returning structure, it is characterized in that: comprise middle body, crankcase and connecting cylinder, described crankcase is connected with middle body, described middle body is connected with connecting cylinder, the bottom of described crankcase and middle body junction surface is offered and is equipped with spill port A, and the bottom of described middle body and connecting cylinder junction surface is provided with spill port B.
Described spill port A comprises the first manhole be arranged on crankcase and the second manhole be arranged on middle body, and described first manhole and the second manhole are butted into spill port A.
Described spill port B comprises the 3rd manhole be arranged on middle body and the 4th manhole be arranged on connecting cylinder, and described 3rd manhole and the 4th manhole are butted into spill port B.
Can be back in crankcase by spill port A and spill port B lubricant oil.
The invention has the beneficial effects as follows:
Piston compressor body oil-returning structure provided by the invention, for various piston compressor type.Compressor block oil-returning structure of the present invention can make the lubricant oil taken out of by piston rod and crosshead again be back in crankcase, thus has the following advantages:
1, the waste of lubricant oil is decreased;
2, avoid lubricant oil accumulation too much and the piston rod of high speed to-and-fro motion high temperature produce and rub;
3, avoiding lubricant oil along with piston rod brings filler, cylinder etc. into.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiments and the drawings, set forth the present invention further, but following embodiment being only the preferred embodiments of the present invention, and not all.Based on the embodiment in mode of execution, those skilled in the art under the prerequisite not making creative work obtain other embodiment, all belong to protection scope of the present invention.

Concrete enforcement:
(1) the second through hole 5 is bored at the slideway lower position of middle body 4, the large I of the second through hole is determined by needing the flow of oil return, and bore first through hole 6 identical with the second through hole 5 size in the position that crankcase 7 is corresponding with the second through hole 5, the first through hole 6 and the second through hole 5 are closely cooperated.
(2) fourth hole 2 is bored at the lower position of connecting cylinder 1, the large I of through hole is determined by needing the flow of oil return, and bore the third through-hole 3 identical with fourth hole 2 size in the position that middle body 4 and fourth hole 2 are corresponding, third through-hole 3 and fourth hole 2 are closely cooperated;
(3) burr is removed to all through holes, acute angle abate.
More than show and describe basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification is only preference of the present invention; be not used for limiting the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
