Background technique
It is very extensive that pressurized air is used in industry.Generally, pressurized air is produced by air compressor.In air compressor system; Can also keep enough pressure in order to ensure whole system under the bigger situation of user's gas consumption; Usually each air compressor system all can be provided with gas holder; Under the normal condition, the pressurized air of elevated pressures is stored in the gas holder, and the gas holder release pressure is to guarantee enough air demands under the bigger situation of user's gas consumption; In addition, in order to ensure the normal operation of system, each air compressor system is provided with multiple air compressors usually, and some of them are machines commonly used, are used to produce pressurized air, and other then are guest machines, and therefore existing compressed air system is actually by air compressor group.And in the middle of operation; There is following problem in an existing pneumatics group of planes: no matter being machine commonly used or guest machine promptly, all is power frequency operation during work, and full power starts; Energy loss is bigger; Whole compressed air system also lacks effective monitoring, and multiple air compressors power frequency operation together is easy to generate pressure surge, therefore is necessary this is improved.
Summary of the invention
The purpose of the utility model is the little pneumatics computers group monitoring of a kind of energy consumption that designs for the deficiency that solves above-mentioned technology, and this pneumatics computers group monitoring can also make whole compressed air system pressure more stable.
The pneumatics computers group monitoring that the utility model designed; Comprise the air compressor that power frequency contactor and output link to each other with gas holder; Said air compressor connects power line through the power frequency contactor; Also comprise frequency variator and be arranged on the pressure sensing cell on the gas holder, described frequency variator connects power line through the power frequency contactor, and described pressure sensing cell signal inputs to said frequency variator; At least two of described air compressors, every air compressor is all to there being the frequency conversion contactor, and described frequency variator is electrically connected respectively with corresponding air compressor through the frequency conversion contactor.
As preferably: described air compressor is a screw-rod air compressor, and quantity is two; Wherein one is machine commonly used, and another is a guest machine, and whole system is more succinct reliable.
As preferably: also comprise the monitoring upper-position unit, this monitoring upper-position unit is communicated by letter with said frequency variator and is connected; Effect of visualization is better like this, and manual operation is more directly perceived.
The pneumatics computers group monitoring that the utility model designed can be provided with pressure and pre-set in the frequency variator, can form an effective closed loop control system between pressure sensing cell, frequency variator, the air compressor, thereby make pressure control more stable; In addition in needs; Frequency variator is through frequency conversion contactor control compressor operation; Frequency variator can effectively be regulated the operate power of air compressor, can pre-set the rotating speed of reasonably controlling air compressor according to force value and the pressure of pressure sensing cell feedback, thereby prevents air compressor in the existing technology is in the power frequency capacity operation once startup state; Thereby effectively reduce power consumption, energy saving.The pneumatics computers group monitoring that the utility model designed, the pressure sensing cell signal carries out real-time monitoring to the pressure in the gas holder, can under the bigger situation of user's gas consumption, guarantee enough pressure, can be adaptable across industrial every field.
