Abstract
The utility model discloses an air cylinder piston for air compressor, belonging to the modification of air cylinder piston for air compressor. The utility model comprises a piston body 3, a piston-rod 8, and an eccentric wheel 9. The air cylinder piston for air compressor is characterized in that the sealing pressure cover 4 of the piston is pressed on a soft abrasion-proof sealing air bowl 6; the sealing pressure cover 4 of the piston and the soft abrasion-proof sealing air bowl 6 are arranged at the end of the piston body 3 through a compressing screw 7. The air cylinder piston for air compressor has the advantages that the material cost is lowered, the sealing performance is improved, the noise is lowered, the energy consumption is reduced, and the service life is prolonged.
Description
(1) technical field
The utility model relates to a kind of improvement of air compressor cylinder piston, a kind of specifically air compressor cylinder piston.
(2) background technique
Existing air compressor cylinder piston adopts the sealing of metallic piston ring substantially, and in order to reduce wear, piston ring and cylinder wall multiselect are got wear-resisting material mutually, have therefore strengthened cost of material.Because air compressor does not allow the discharging of oil gas, cylinder piston is many works under the situation of not having oil, and more easy to wear between piston ring and the cylinder wall, piston very easily leaks gas, and leak rate even up to 30% had both been wasted the energy, had reduced working life again.Because piston ring and cylinder wall all are metallic material, thus quick abrasion, easily gas leakage, noise is big, and high energy consumption is the problem that existing air compressor cylinder piston exists always.
(3) summary of the invention
The purpose of this utility model is to overcome the shortcoming in the above-mentioned technology, a kind of air compressor cylinder piston is provided, it is the cylinder piston that combines by metal and software high-abrasive material, utilize metallic material to do the piston skeleton, high-abrasive material is done Sealing, make cylinder piston when work, software high-abrasive material and cylinder wall produce friction, rather than produce friction between metal and the metal.Can improve sealability, reduce energy consumption, reduce noise, increase the service life.
The purpose of this utility model is realized by following technological scheme: this air compressor cylinder piston comprises piston body 3, piston rod 8, eccentric wheel 9, it is characterized in that piston seal gland 4 is pressed on the software wear-resistant seal gas bowl 6, and piston seal gland 4 and software wear-resistant seal gas bowl 6 are fixed on the end of piston body 3 by housing pin 7, form the pistons end sealing.
The outer wall of piston body 3 is fluted, and groove is embedded with software wear-resistant seal ring 5, and software wear-resistant seal ring 5 contacts with cylinder wall during work, plays the role of positioning, and also forms piston wall portion annular seal simultaneously.
The inner hole sleeve of software wear-resistant seal gas bowl 6 is contained on the boss cylindrical of piston seal gland 4, and the convex surface that inwall is close to piston seal gland 4 becomes bowl-shape, forms the pistons end sealing jointly with cylinder wall.
The utility model has the advantages that: cylinder piston is that software high-abrasive material and cylinder wall produce friction, rather than produces friction between metal and the metal when work.Therefore cost of material reduces, and sealability improves, and noise reduces, and energy consumption reduces, and has prolonged working life.

Fig. 1 is that the utility model is contained in the working state schematic representation in the cylinder,
Fig. 2 is that the utility model removes piston rod, eccentric generalized section,
Fig. 3 is that generalized section is looked on the left side of Fig. 2,
(5) embodiment
The inner hole sleeve of teflon software wear-resistant seal gas bowl 6 is contained on the boss cylindrical of piston seal gland 4, piston seal gland 4 is pressed in above the blanket gas bowl 6, with four housing pins 7 piston seal gland 4 and blanket gas bowl 6 are fixed on the end of piston body 3, blanket gas bowl 6 forms the pistons end sealing with cylinder wall at work.Simultaneously, the outer wall of piston body 3 is fluted, and groove is embedded with teflon software wear-resistant seal ring 5, and during work, software wear-resistant seal ring 5 contacts with cylinder wall, plays the role of positioning, and forms piston wall portion annular seal simultaneously.Inlet and outlet hole control intake and exhaust on the valve plate, piston by piston rod 8, drive eccentric wheel 9 and rotate in to-and-fro motion.
Claims (3)
