Abstract
The utility model relates to a screw rod type water cooling air compressor energy-saving structure belonging to the technical field of electric control of air compressors. The technical scheme is that The screw rod type water cooling air compressor energy-saving structure comprises an air compressor I (2), an air compressor II (3), a frequency control cabinet (1) and a pressure tank (4), wherein the air compressor I and the air compressor II are arranged in parallel so as to connect with the pressure tank, the frequency control cabinet is connected with the air compressor I and the air compressor II, and a frequency control cabinet is connected with the air compressor I and the air compressor II and is internally provided with a frequency converter. The screw rod type water cooling air compressor energy-saving structure provided by the utility model has the positive effects that the frequency control cabinet is additionally arranged, the power supply consumption is reduced, and the loading and unloading times of the air compressors are reduced; compared with the electric power consumption of a background technology, the screw rod type water cooling air compressor energy-saving structure has the advantages that 54832 kW.h of electricity is saved each year, and the electricity saving ratio is 17%, so that an energy-saving purpose is realized; and the operation of the air compressors is stable, the loading and unloading times are obviously reduced, so that the equipment failure rate is reduced, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of Worm type water-cooled air compressor energy-saving structure, belongs to the Electrical Control Technology field of air compressor.
Background technique
At present, large-scale assembling factory building is generally set up place's air compressor plant, is equipped with two screw air compressors, zoning supply pressurized air, about 340,000 kWh of air compressor year power consumption, power consumption is larger, and main cause is as follows: 1. air compressor ubiquity " low load with strong power " phenomenon; During the configuration type selecting, the air compressor nominal configuration all is higher than system's gas demand, and in fact maximum load just is interrupted appearance, and load is much smaller At All Other Times, and the pressurized air utilization rate is low.2. there is defective in air compressor (frequently fixed) method of operation; Background technique air compressor air feed adopts pressure upper and lower limit control mode, and on-load pressure (lower limit A) is a little more than demand pressure, and unloading pressure (upper limit B) is a little less than the air compressor rated pressure; When air compressor supply gas pressure during greater than the B value, air compressor stops air feed and is in unloaded state, empty load of motor operation this moment; Be down to down in limited time when the compressor working pressure, air compressor begins automatically to load air feed, so repeatedly; This control mode makes system pressure have certain fluctuation, and air compressor A point loading current moment impact is large, Bands carrying row power consumpiton is high, B point off-load rear motor idle running standby, electric energy effective consumption.And demand and air demand difference are larger, load, unloading is just more frequent, and system energy consumption is just higher.
The model utility content
The purpose of this utility model provides a kind of Worm type water-cooled air compressor energy-saving structure, installs variable frequency speed control cabinet additional, reduces power consumption, reduces air compressor and loads, unloads number of times, solves the problems referred to above that background technique exists.
The technical solution of the utility model is: Worm type water-cooled air compressor energy-saving structure, comprise air compressor one, air compressor two, variable frequency speed control cabinet and pressurized tank, air compressor one and air compressor two are arranged in parallel, and are connected with pressurized tank, and variable frequency speed control cabinet connects air compressor one and air compressor two.
A variable frequency speed control cabinet connects air compressor one and air compressor two, is provided with frequency variator in the variable frequency speed control cabinet, the frequency variator one drag two, and the frequency conversion of two air compressors of realization/power frequency is switched.
Good effect of the present utility model: install variable frequency speed control cabinet additional, reduce power consumption, reduce air compressor and load, unload number of times; The power consumption of contrast background technique, year economize on electricity 54832kWh, power saving rate 17% has been realized energy-conservation purpose; Compressor operation is steady, and the loading and unloading number of times obviously reduces, and equipment failure rate reduces, and prolong working life.
Description of drawings
Fig. 1 is schematic representation of the present utility model;
Among the figure: variable frequency speed control cabinet 1, air compressor 1, air compressor 23, pressurized tank 4.
Embodiment
Below in conjunction with accompanying drawing, by embodiment the utility model is described further.
Worm type water-cooled air compressor energy-saving structure comprises air compressor 1, air compressor 23, variable frequency speed control cabinet 1 and pressurized tank 4, and air compressor one and air compressor two are arranged in parallel, and are connected with pressurized tank, and variable frequency speed control cabinet connects air compressor one and air compressor two.A variable frequency speed control cabinet connects air compressor one and air compressor two, is provided with frequency variator in the variable frequency speed control cabinet, the frequency variator one drag two, and the frequency conversion of two air compressors of realization/power frequency is switched.
Adopt frequency variator one drag two pattern, frequency variator is selected by mode switch, can be assigned to any air compressor and carry out VFC, and other one then is in the power frequency state.Only opening at ordinary times an air compressor can satisfy, and the air compressor of unlatching switches to corresponding VFC state.Consider frequency of utilization and the life-span thereof of two air compressors, so require the operator to switch weekly the single-conversion state of a control.
Claims (2)
