Abstract
The utility model relates to a complete oil-free lubrication gas compressor of a reciprocating piston, which is characterized in that the complete machine utilizes an up and down structure. A main machine is arranged on a base of a support. A motor and a cooler are arranged at the top surface of the support. An independent fan is arranged under the cooler. An air suction header is fixed at the lateral side of the support. The main machine utilizes crank-connecting rod mechanism which is a sector structure formed by the four connecting rods and the four pistons and utilizes a combination valve which is formed by an air suction valve and a vent valve. Flange sealing surfaces are formed by an 'O'-shaped ring at air suction ports and exhaust ports. The four air suction ports are connected with the air suction header through metal flexible pipes. A positive-negative pressure shaft seal is arranged in a bearing seat cover. The seal plane of the bearing seat cover is provided with the 'O'-shaped ring. The complete oil-free lubrication gas compressor of the reciprocating piston improves security of the compressed gas, reduces quantity of the compressive leakage of the working medium, improves working efficiency, reduces seal pressure of the positive-negative pressure shaft seal, and can be applied to departments, such as war industries, oxygen generation, nitrogen generation, chemical industries, oil gas recovery, research institutions and the like.

Technical field
The utility model belongs to the universal machine field, relates to a kind ofly need not adding lubricant oil, discharges gas and does not contain greasy dirt, does not pollute working medium, leak free gas compressor, particularly a kind of full-oil-free lubrication reciprocating piston gas compressor.
Background technique
At present, the full-oil-free lubrication piston formula compressor of domestic production, its structural design all is to design for pressurized air specially basically, the system oxygen supercharging of the market demand is carried, the supercharging of system nitrogen is carried, process cycles, the microminiature compressor that departments such as noble gas recovery need mostly is the air compressor repacking, because congenital design deficiency has caused interior leakage be air to compressor internal leakage and outer leakage is that the compressor operating medium is serious to the compressor external leakage, interior leakage seriously can cause working medium purity with low, external leakage seriously can cause working medium to run off, and waste is serious.Traditional compressor also exists: 1, adopt Reed Valve, if fracture appears in valve block, cause delivery temperature to raise, have very big potential safety hazard; 2, the asbestos packing sealing is adopted on the plane, and gas permeation is obvious; 3, to add the sealer sealing reliability with screw thread poor for cylinder head and pipe joint; 4, positive and negative last item envelope seals very problems such as difficulty.Therefore it is recycling to be difficult to adapt to military project oxygen, and medical oxygen producing is carried, and departments such as system nitrogen supercharging use, and buy imported compressor to cost an arm and a leg, and domestic price is tens times often.
Summary of the invention
The utility model has overcome the defective of above-mentioned existence, purpose is for solving gas compressor on the basis that guarantees full-oil-free lubrication, discharge gas and do not contain greasy dirt, do not pollute working medium, reduce internal leakage and external leakage, guarantee gas purity simultaneously and reduce noble gas to run off, a kind of full-oil-free lubrication reciprocating piston gas compressor is provided.
The utility model full-oil-free lubrication reciprocating piston gas compressor content Description:
The utility model full-oil-free lubrication reciprocating piston gas compressor, it is characterized in that: complete machine adopts upper and lower structure, main frame is arranged on the base of bearing, motor, cooler are arranged on the end face of bearing, be provided with independently blower fan below cooler, suction manifold is fixed on the side of bearing; Main frame adopts connecting rod, and by four connecting rods, four pistons are formed sector structure; Adopt combination brake switch and proporting that Aspirating valves, outlet valve are located on the valve body, intakeport is established at the top of cylinder head, and relief opening is established in the side, forms flange facing at intakeport and relief opening by round section joint ring; Four intakepories are connected with suction manifold by metallic hose; In positive and negative last item envelope was arranged in the pedestal cap, the pedestal cap sealing plane was provided with round section joint ring.
Piston is provided with three road piston ring grooves, is provided with the twice piston ring in each piston ring groove.
In positive and negative last item envelope, be provided with metal frame, be provided with three seals lip and three road springs in the metal frame.
The utility model full-oil-free lubrication reciprocating piston gas compressor is specially for not allowing the lubricant pollution working medium also not allow simultaneously to leak to reduce working medium purity or cause design such as working medium loss in the supercharging, process cycles process.Adopt the combination brake switch and proporting structure, increase the pressurized gas Security; Establish three road piston ring grooves on the piston, establish the twice piston ring in each groove, reduced working medium and leaked decrement, increase work efficiency, reduce positive and negative last item envelope sealing load.Departments such as the utility model can the extensive use military project, system oxygen, system nitrogen, chemical industry, oil gas recovery, scientific research institutions.
