Model utility content
The utility model solves the technical problem that domestic PET bottle blowing piston type oil-free air compressor exhaust pressure is low, stroke value coupling is incorrect, mean piston speed is high.For this reason, the utility model provides a kind of oil-free air compressor, and it has safe, reliable, durable energy saving, easy maintenance, microseism low noise, the advantage of price performance brilliance.
To achieve these goals, the utility model adopts following technological scheme.
A kind of oil-free air compressor, comprises motor, main frame, gas holder, base, cooling water pipeline; Motor, main frame, gas holder are arranged on base, and main frame comprises crankcase, bent axle, first order cylinder, second level cylinder, third level cylinder, fourth stage cylinder; Described motor is connected with bent axle, and first order cylinder, second level cylinder, third level cylinder, fourth stage cylinder, gas holder are connected successively by air pipe; Air pipe between described first order cylinder and second level cylinder, between second level cylinder and third level cylinder, between third level cylinder and fourth stage cylinder, between fourth stage cylinder and gas holder is respectively equipped with first order cooler, second-stage cooler, third level cooler, fourth stage cooler, described cooling water pipeline is connected with first order cylinder, second level cylinder, third level cylinder, fourth stage cylinder, first order cooler, second-stage cooler, third level cooler, fourth stage cooler respectively.
Described oil-free air compressor also comprises electric lubricating oil heater, and electric lubricating oil heater is arranged on crankcase, has expanded compressor operating region.
Described crankcase is also connected with first order cylinder, second level cylinder, third level cylinder, fourth stage cylinder respectively by middle body.
Main frame belongs to V-type angled type, and first order cylinder, third level cylinder are a row cylinder, and second level cylinder, fourth stage cylinder are two row cylinders, and the reciprocating motion of the pistons fourth stage compresses.Cylinder, cooler have water to cool.Bent axle, connecting rod, crosshead carry out pressure lubrication by spindle nose rotor pump.
The utility model can also be provided with pressure regulating system, safety system and drainage.
Pressure regulating system adopts PLC computer controller, two five-way electromagnetic valves, unloading valves complete.
In safety system, every grade is provided with safety valve, the protection of PLC computer controller exhaust pressure, lubricating oil pressure, lubricating oil temperature, cooling water pressure, power of motor.
In drainage, PLC conputer controlled automatic pollution discharge.
The piston stroke of the main frame of the utility model oil-free air compressor can be 100mm, speed of crankshaft 740r/min.The boundary dimension of oil-free gas compressor is that 2762 mm(are long) × 2284 mm(are wide) × 2040 mm(are high).
The utility model comprises following beneficial effect: the crankcase of oil-free air compressor main frame, can bear internal air pressure when needed, can form gas No leakage compressor.The engineering plastics element of transmission part and sealing gas, its supporting plane specific pressure value is all low, so wear and tear little, the life-span is long, tolerance, the pressure of compressor are also unattenuated, and power consumpiton does not also increase, and has the feature of durable energy saving.The same tolerance of boundary dimension much smaller than other structural types, the compressor of pressure, easy maintenance.Thoroughly balance rotating inertia force and the first order reciprocating inertia force, it is the optimum state that V-type compressor can reach in principle, the oil-free air compressor group making quick mounting in place can foundation-free, without vibration damper, be floated on the smooth running at full capacity of horizontal hardstand without pressing plate, compressor house cost also falls sharply.The advantages such as it is high that the utility model has exhaust pressure, and safe, reliable, durable energy saving, easy maintenance, microseism low noise, price performance are remarkable.Certainly, implement arbitrary product of the present utility model might not need to reach above-described all advantages simultaneously.
