Abstract
A medium-pressure mobile type piston air compressor comprises a case body, an air compressor main machine, a cooler assembly, an air cleaner and the like. An exhaust fan in the cooler assembly is arranged toward a cylinder end of the air compressor main machine. The medium-pressure mobile type piston air compressor is characterized in that an air guide cover is arranged on the periphery of the exhaust fan, separation plates are arranged on the two sides of the air guide cover, the cooler assembly and the case body are connected into a whole through the separation plates. After the air guide cover is additionally arranged on an air outlet of the exhaust fan, cooling air blowing toward the cylinder end of the air compressor main machine turns centralized and strong, and thus cooling effects on the air compressor main machine are promoted. Moreover, after the cooler assembly and the case body are connected into a whole through the separation plates, the separation plates not only play a role in guiding air, but also enable vibration noise of the whole machine to be effectively lowered. Furthermore, an air inlet of the air cleaner is arranged outside the case body, and thus hot air inside the whole machine can be prevented from entering into the air compressor main machine. Due to the improvements, the rated air exhaust capacity of the medium-pressure mobile type piston air compressor can be increased to 10-15, and exhaust pressure can be increased to over 1.2MPa.
Description
[technical field]
The utility model relates to the portable piston air compressor of a kind of middle pressure.
[background technique]
At present, in the public technology, engineering is to provide pressurized air for Down-hole rolling rig or other with the gas instrument with the effect of piston air compressor, and its supporting power is generally two kinds on diesel engine or motor.Wherein, the structure of the portable piston air compressor of middle pressure take motor as driving force, generally include the envelope that is placed on the vehicle type chassis assembly, and be arranged on the air compressor host in the envelope, the motor of driving host work, be the interstage cooler of guaranteeing that the air compressor host normal operation arranges.This cooler is arranged on the air compressor host end, plays the hot air acting that the compression of cooling main frame one-level is discharged, to guarantee the air compressor host normal operation.The portable piston air compressor of middle pressure of this structure is the following problem of ubiquity in actual applications: 1, cooling effect is poor: the relative cylinder head setting of interstage cooler, ventilating fan is dried towards cylinder head, but, because reasons in structure, so that blowing to the wind-force of cylinder head, ventilating fan is in dispersed state, concentration degree is poor, thereby has affected cooling effect.2, the air compressor host suction port is arranged on envelope inside, so that it is relatively higher to enter the gas source temperature of air compressor host, and then has affected the raising of overall performance.Owing to can't solve the cooling problem, so that the volume flow of existing machine is generally less than 12
, exhaust pressure generally below 0.7Mpa, is difficult to satisfy pressurized gas user's work requirements.
[summary of the invention]
For solving the problems of the technologies described above, the utility model aims to provide the portable piston air compressor of a kind of middle pressure, this machine has effectively improved the cooling effect to air compressor host, so that the specified air displacement of complete machine can be brought up to 10-15 by to the isostructural improvement of middle cooler
, exhaust pressure can be brought up to more than the 1.2MPa.
For solving the problems of the technologies described above, the utility model has adopted following technical proposals, the portable piston air compressor of this middle pressure, comprise envelope, and be arranged on air compressor host in the described envelope, chiller assembly, the suction port of described air compressor host is provided with air-strainer, described chiller assembly is placed in a side of described air compressor host, ventilating fan in this chiller assembly is towards the cylinder head setting of described air compressor host, it is characterized in that: at the outer wind scooper that is arranged with of described ventilating fan, both sides at this wind scooper are provided with dividing plate, and described dividing plate is connected into one with described chiller assembly and envelope.
During as preferred implementation, be provided with the air filter suction tude between the suction port of described air compressor host and the described air-strainer, the suction port of this air-strainer is arranged on outside the described envelope.
During as preferred implementation, described interstage cooler is strip-fin oil cooler.
Beneficial effect: compared with prior art, the utility model becomes concentrated and strong so that blow to the cooling air of air compressor host cylinder head after the exhaust outlet of ventilating fan is set up wind scooper, thereby has improved the cooling effect to air compressor host; Moreover after described dividing plate was connected into one with chiller assembly and envelope, dividing plate can not only play the wind-guiding effect, makes the vibration noise of complete machine obtain effective reduction, prevents that hot air flow is back to the effect of intake grill but also play.Secondly, by the connection of air filter suction tude, the suction port of air-strainer is arranged on outside the described envelope, thereby can avoids the hot air flow of complete machine inside to enter air compressor host.By above-mentioned improvement, effectively improved the cooling effect to air compressor host, so that the specified air displacement of complete machine can be brought up to 10-15
, exhaust pressure can be brought up to more than the 1.2MPa.
The utility model is described further by embodiment below in conjunction with accompanying drawing.
