Abstract

The utility model discloses a piston type air compressor for a braking system of an agricultural vehicle, which comprises a cylinder and pistons assorted with the cylinder. An oil circular groove and three gas ring slots are arranged on the piston on the upper portion of the cylinder, an oil ring slot is disposed on the piston on the lower portion of the cylinder, and correspondingly assorted oil rings and correspondingly assorted gas rings are respectively arranged on the oil ring slots and the gas ring slots. By the aid of integrated innovation of the oil rings and the gas rings of the pistons, abrasion resistance and air tightness of the cylinder are improved, the quantity of mixed oil is reduced, and the service life of the air compressor is prolonged.

Description

A kind of agricultural vehicle use for brake system piston type air compressor
Technical field
The utility model relates to a kind of air compressor, is specifically related to a kind of agricultural vehicle use for brake system piston type air compressor.
Background technique
Piston type air compressor has advantages such as manipulation is light, reliable operation, maintenance facility, is widely used in the braking system of agricultural vehicle.China is large agricultural country, and agricultural vehicle enormous amount, and annual all with very big speed increment arrive whole traffic safety with the security relationship of car braking system, so the reliability of agricultural vehicle braking system seems more and more important.
Cylinder body and piston are two essential elements of piston type air compressor.But at present usually on the supporting piston of cylinder body, have only oil ring and twice compression ring, tightness and oil sealing property are difficult to be guaranteed after long-term the use, be prone to scurry oil mass greatly, shortcoming such as poor air-tightness.
The model utility content
The purpose of the utility model is to provide a kind of agricultural vehicle use for brake system piston type air compressor; Through integrated innovation to oil piston ring, compression ring; Improve the wear resistance and the tightness of cylinder body, reduced and scurried oil mass, prolonged the working life of air compressor.
The utility model adopts following technological scheme:
A kind of agricultural vehicle use for brake system piston type air compressor; Comprise cylinder body and with the supporting piston of cylinder body; Wherein, The piston on said cylinder body top is provided with oil ring groove and three compressions, and the piston of inferior part of the cylinder block is provided with an oil ring groove, and corresponding supporting oil ring and compression ring are set respectively on said oil ring groove and compression.
The beneficial effect of the utility model is:
Compression and oil ring groove have been set up on the utility model piston; Change one oil ring that disposes on original piston, twice compression ring into twice oil ring, three road compression rings; Reasonably increased the quantity of compression ring and oil ring, do not influenced under the prerequisite of compressor operating efficient, effectively improved tightness in assurance; Increase air displacement and exhaust pressure, air displacement is by 0.03m 3/ min is promoted to 0.038 m 3/ min.Reduce to scurry oil mass simultaneously, scurry oil mass and reduce to 0.25g/h, improved product performance greatly by≤0.5g/h.Experiment showed, that the air compressor machine life after the improvement prolongs 1.5 times.
Simultaneously the piston of the utility model changes twice oil ring, three road compression rings into by one original oil ring, twice compression ring, scurries oil mass after the improvement and reduces, and reduces to 0.25g/h by≤0.5g/h, and tightness increases simultaneously, air displacement increases, by 0.03m 3/ min is promoted to 0.038 m 3/ min, braking effect strengthens.
Description of drawings
Fig. 1 is that the master of the utility model looks schematic representation;
Fig. 2 is that generalized section is looked on the left side of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
As shown in Figure 1; The utility model comprise cylinder body 1 and with the supporting piston 2 of cylinder body 1; The piston 2 on cylinder body 1 top is provided with oil ring groove 4 and three compressions 3; Three compressions 3 are positioned at the top of oil ring groove 4, and the piston 2 of cylinder body 1 bottom is provided with an oil ring groove 4, on oil ring groove 4 and compression 3, corresponding supporting oil ring and compression ring are set respectively.
The utility model has been set up compression 3 and oil ring groove 4 on piston 2; One oil ring that disposes on the piston with original piston type air compressor, twice compression ring change twice oil ring, three road compression rings into, have reasonably increased the quantity of compression ring and oil ring, do not influence under the prerequisite of compressor operating efficient in assurance like this; Effectively improved tightness; Increase air displacement and exhaust pressure, tightness increase simultaneously, air displacement increase, and are strengthened by braking effect.
Explanation is at last; Above embodiment is only unrestricted in order to the technological scheme of explanation the utility model; Other modifications that those of ordinary skills make the technological scheme of the utility model perhaps are equal to replacement; Only otherwise break away from the spirit and the scope of the utility model technological scheme, all should be encompassed in the middle of the claim scope of the utility model.
