Technical field
The utility model belongs to air compressor technical field, particularly a kind of small-sized piston type air compressor.
Background technique
Air compressor is widely used in industrial every field, it is a kind of general machinery equipment, piston type air compressor is wherein formed primarily of cylinder, piston, piston rod, slidercrank mechanism, gas holder and motor, driven by motor crank rotates, crank drives slide block to-and-fro motion by connecting rod, slide block then drives the piston reciprocates of cylinder interior carry out air-breathing and calm the anger by piston rod, and pressurized air is depressed in gas holder and stores.
When air pressure in gas holder reaches 0.7MPA; motor stopping; when pressurized air exports; air pressure in gas holder lowers gradually; the pressure of institute's output squeezing air also step-down thereupon; when the Pressure Drop in gas holder is to 0.5-0.6MPA; motor restarts work; pressure in gas holder is supplemented to 0.7MPA again, and therefore the pressure of the air compressor institute output squeezing air of this structure does not stop fluctuation change, cannot export the pressurized air of a steady pressure; in addition; this air compressor must be equipped with a gas holder, and cost is high, and carries trouble.
Model utility content
The purpose of this utility model is for the problems referred to above existing for existing mini air compressor, and proposes a kind of compressed-air actuated air compressor of energy stable output pressure.
The purpose of this utility model realizes by following technical proposal:
A kind of air compressor, comprise cylinder, compressing mechanism and motor, compressing mechanism is arranged in the cylinder body of cylinder, motor-driven compressor structure carries out air compressing, the cylinder body of cylinder offers the suction port be communicated with inner chamber of cylinder block and relief opening, it is characterized in that, described air compressor also includes pressure transducer and drive controller, pressure transducer is arranged on exhaust ports for detecting the air pressure of the pressurized gas of cylinder discharge, drive controller and pressure transducer and motor are electrically connected, drive controller controls motor speed to adjust compression horsepower according to the delivery pressure that pressure transducer detects.
Gas compression is carried out in the work of motor-driven compressor structure, pressurized gas is exported by relief opening, the pressure transducer of exhaust ports detects the pressure of output squeezing air constantly, when the pressure detected and setting value have deviation, drive controller regulates motor speed, and the compressed-air actuated pressure of output and setting value are consistent.
In above-mentioned air compressor, described motor is brushless electric machine.
In above-mentioned air compressor, described suction port and exhaust ports are respectively equipped with Aspirating valves and outlet valve.
In above-mentioned air compressor, described compressing mechanism comprises piston, piston rod, slide block and crank, motor driving crank rotates, one end of described piston rod is connected with piston, the other end is connected with slide block, slide block is provided with connecting rod relative to the opposite side of piston rod, and the two ends of connecting rod are connected with slide block and crank respectively.
In above-mentioned air compressor, described air compressor also includes operation panel and pressure gauge, and operation panel and pressure gauge are all electrically connected with drive controller.User arranges the air pressure size of air compressor institute output squeezing air by operation panel, the actual pressure of pressure gauge display translation.
Compared with prior art, this air compressor eliminates traditional gas holder, and pressurized gas directly exports, and volume is little, is easy to carry.Utilize brushless electric machine to be convenient to the characteristic controlled, drive controller directly can control motor speed, regulates the air pressure size of institute's output squeezing gas, makes it remain on a stationary value.
