Description
The technical field is as follows:
the utility model relates to a tiny-oil screw air compressor machine air inlet control device with adjustable.
The background art comprises the following steps:
the air inlet control of the screw air compressor comprises three modes of loading and unloading, frequency conversion and capacity modulation. At present, the air inlet control mode of the Conpruai air compressor of the Mianchi power plant is a loading and unloading mode, and an air inlet valve is only in a full-open state and a full-closed state. Therefore, when the air displacement of the air compressor unit is greater than the air consumption, the air compressor unit is automatically unloaded, and when the system pressure is reduced to the lower set limit in operation, the air compressor unit is automatically loaded so as to keep the balance of the air consumption. The exhaust pressure and the motor current in the control mode are poor in linearity and generally in a sawtooth shape. Therefore, frequent fluctuation of air consumption of the system is caused, the motor and the host bear larger impact load, the service life of equipment is further influenced, the power consumption of the motor is greatly increased when the air compressor runs from unloading to loading, and the energy saving effect in running is poor.
The utility model has the following contents:
the utility model aims at solving the problem that exists above-mentioned, provide a tiny-oil screw air compressor machine air inlet control device with adjustable.
The above purpose is realized by the following technical scheme:
an adjustable air inlet control device of a micro-oil screw air compressor comprises an air inlet valve assembly, a first lever, a second lever, a sliding rod and a spring, wherein the middle end of the first lever is hinged to a base through a hinge point, the top of the second lever is hung on the base through a hanging point, and the bottom of the first lever is connected with the bottom of the second lever through the spring;
a sliding seat is fixed on the base, the sliding rod is in sliding fit with the sliding seat, a fixed point is fixed in the middle of the sliding rod, a roller wheel is connected in the middle of the second lever, and the roller wheel is in contact with the fixed point of the sliding rod;
and a swing rod of the air inlet valve assembly is fixed with the slide rod.
The adjustable air inlet control device of the micro-oil screw air compressor is characterized in that the fixed point is a cam.
In the adjustable air inlet control device of the micro-oil screw air compressor, one end of the first lever is aligned to a pipeline pressure signal, and the other end of the first lever is aligned to the nozzle.
The adjustable air inlet control device of the micro-oil screw air compressor is characterized in that a baffle is fixed at one end of the first lever, which is aligned with the nozzle.
Has the advantages that:
1. the utility model discloses admission valve with hold mode of transfer is the pneumatic automatic control of pure machinery, does not receive original PLC control logic to influence, also need not modify existing control logic.
2. The utility model discloses a principle is that the proportional control valve adjusts the valve plate aperture that admits air according to system pressure change proportion, and the aperture through the valve plate that admits air of discharge mechanism control reaches the balance with outlet pipeline pressure signal change.
3. The utility model discloses can effectively avoid avoiding equipment frequently to add the uninstallation, prevent that system's pressure is undulant by a wide margin, reduce the impact of fluctuating current to the motor, reduce equipment defect, improve equipment reliability.
The air inlet control mode is optimized, so that the air inlet valve has a certain capacity adjusting function, and the air inlet control device has the functions of controlling the air inlet amount of the air inlet valve and maintaining the pressure stability of the system. When the pipeline pressure signal rises gradually, the pressure signal is higher than the pressure signal of the nozzle, so that the first lever rotates anticlockwise, the bottom of the first lever is connected with the bottom of the second lever through a spring, the second lever is pulled to rotate, the middle part of the second lever is connected with a roller, the roller is contacted with a cam of a sliding rod, the sliding rod is pushed to slide along with the rotation of the second lever, the sliding rod is fixed with a swinging rod, so that the swinging rod is driven to move, the swinging rod is connected with a valve rod of a valve body through a connecting rod (the connection is the prior art), so that the opening degree of the valve body is adjusted, the opening degree of the valve plate can be automatically adjusted according to the change of the outlet pressure of the air compressor of the system, the air consumption and the air suction quantity are balanced and matched, and the pressure and the current tend to be linear. The frequent loading and unloading of the equipment are avoided, the large-amplitude fluctuation of the system pressure is prevented, the impact of the fluctuation current on the motor is reduced, the service life of the equipment is prolonged, and the energy-saving effect is realized.
