Description
[technical field]
The utility model relates to a kind of energy-saving control device for air compressor with motor speed adjusting function.
[background technique]
At present, the air compressor of selling on market adopts the acting of motoring compressor head, air compressing is arrived to gas holder, the pressure size shows by pressure gauge, pressure reaches the force value that pressure relay is set, the pressure relay action, the A.C. contactor that to control motor work by relay contact disconnects, motor is quit work, in gas holder, gas pressure just can not increase again, such air compressor is in using process, owing to often needing to supplement the gas holder inner air pressure, motor switches in the stop and start two states of being everlasting, there is the large and easy damaging features of equipment of the sound, simultaneously, being not easy to energy saving controls.
On the other hand; air compressor is generally regulated the aperture of suction valve by the gas holder internal pressure; when make the gas holder internal pressure when the suction valve pressure threshold value fluctuates up and down due to working principle, there will be suction valve often to turn down or close phenomenon, after suction valve is closed; the rotation of motor is also only understood power consumption and is not done work; its output power is larger, and rotating speed is higher, causes waste of energy larger; and motor also often can switch in the stop and start two states, mechanical wear is large.
Therefore, be necessary to solve as above problem.
[model utility content]
The utility model has overcome the deficiency of above-mentioned technology, a kind of energy-saving control device for air compressor with motor power (output) regulatory function is provided, motor driver is regulated output power of motor according to the feedback signal of pressure transducer, control the compressor head acting to regulate its rotating speed, stable control gas holder internal pressure, be convenient to energy saving.
For achieving the above object, the utility model has adopted following technical proposal:
A kind of energy-saving control device for air compressor with motor power (output) regulatory function, include controller 1 and for compressed-air actuated compressor head 2, described compressor head 2 inlet ends are provided with suction valve 3, compressor head 2 outlet sides are provided with gas holder 4, described gas holder 4 output terminals are provided with outlet valve switch 5, on described compressor head 2, be connected with for driving its compressed-air actuated motor 23, described gas holder 4 is provided with the pressure transducer 6 for detection of its internal pressure, be electrically connected with pressure transmitter 7 between described pressure transducer 6 and controller 1, be electrically connected with the motor driver 8 of regulating motor 23 output powers according to the feedback signal of pressure transducer 6 between described controller 1 and motor 23.
Also be provided with the Decompression valves 9 for safety protection on described gas holder 4.
The appearance be provided with between described gas holder 4 and suction valve 3 for control suction valve 3 apertures according to gas holder 4 internal pressures is adjusted valve 10.
Compared with prior art, the beneficial effects of the utility model are:
1, by between controller and motor, being provided with motor driver, can control the smooth starting of motor low speed, make air compressor send the sound and fall littlely, the temperature rise of air compressor is also relatively low, and mechanical wear is little, is conducive to extend the air compressor life-span.
2, realized the closed loop control of air compressor, motor driver can be regulated output power of motor according to the feedback signal of pressure transducer, to regulate its rotating speed, controls the compressor head acting, and stable control gas holder internal pressure, be convenient to energy saving.
3, by Decompression valves being set on gas holder and between gas holder and suction valve, Rong Tiaofa being set, when the gas holder internal pressure surpasses the Decompression valves threshold values, Decompression valves carries out pressure release, holds the aperture of adjusting valve suitably to control suction valve, plays the dual security protection function.
Even 4 gas holder internal pressures often fluctuate, the pipe network demand volume changes, and motor can not switch in the stop and start two states of being everlasting yet, and is beneficial to and extends the air compressor life-span.
[accompanying drawing explanation]
Fig. 1 is block diagram of the present utility model.
[embodiment]
Below in conjunction with accompanying drawing, by embodiment, the utility model feature and other correlated characteristic are described in further detail, so that technician's of the same trade understanding:
As shown in Figure 1, a kind of energy-saving control device for air compressor with motor power (output) regulatory function, it is characterized in that including controller 1 and for compressed-air actuated compressor head 2, described compressor head 2 inlet ends are provided with suction valve 3, compressor head 2 outlet sides are provided with gas holder 4, described gas holder 4 output terminals are provided with outlet valve switch 5, on described compressor head 2, be connected with for driving its compressed-air actuated motor 23, described gas holder 4 is provided with the pressure transducer 6 for detection of its internal pressure, be electrically connected with pressure transmitter 7 between described pressure transducer 6 and controller 1, be electrically connected with the motor driver 8 of regulating motor 23 output powers according to the feedback signal of pressure transducer 6 between described controller 1 and motor 23.
Motor driver 8 as above can adopt motor PWM power driver module general on market or other to have the motor rotational speed control apparatus that current/voltage is controlled function.
During work, when the pipe network demand volume is larger, pressure transducer 6 detects pressure drop, and the output power by motor driver 8 suitable increasing motor 23, improve its rotating speed, supplements gas holder 4 internal pressures.
When the pipe network demand volume is less, pressure transducer 6 detects pressure rise, suitably reduces the output power of motor 23 by motor driver 8, reduces its rotating speed, when guaranteeing normal trouble free service, reaches the purpose of energy saving.
Also be provided with the Decompression valves 9 for safety protection on gas holder 4 as above, be conducive to guarantee that gas holder 4 internal pressures are below safe threshold values.
Be provided with between gas holder 4 as above and suction valve 3 to hold and adjust valve 10, the effect of holding tune valve 10 is the aperture of according to gas holder 4 internal pressures, suitably regulating suction valve 3, when gas holder 4 internal pressures when large, reduce suction valve 3 apertures, pressure hour, improve suction valve 3 apertures, so, when the malfunctioning and gas holder of Decompression valves 94 internal pressures increase, adjust valve 10 to trigger to turn down by appearance and even close suction valve 3, suitable control inputs air mass flow, after closing suction valve 3, there is no input air, even compressor head 2 is also in running, gas holder 4 internal pressures can not increase yet again, thereby play the function of multiple protective, until gas holder 4 internal pressures are not opened suction valve 3 after not transfiniting again.
As mentioned above, this case controller 1 is controlled by the output power of 8 pairs of motor 23 of motor driver, makes it adapt to the pipe network demand volume, like this, motor 23 just need to not switch in the stop and start two states, and mechanical wear is little, is conducive to extend the air compressor life-span.
As mentioned above, what this case was protected is a kind of energy-saving control device for air compressor with motor speed adjusting function, and all technological schemes identical or close with this case structure all are shown in the protection domain that falls into this case.
