Abstract

The invention relates to an independent air supply device and a using method thereof. The independent air supply device comprises a plurality of air compressors, a pipeline, a pressure sensor and a controller, wherein output ports of the air compressors are connected with the same pipeline, and air directly enters an air storage bag of a weaving machine; the air storage bag of the weaving machine is provided with the pressure sensor connected with the controller; the pressure sensor feeds a pressure value of the pipeline back to the controller through an electronic signal. The pressure sensor detects an actual pressure value P at an air inlet of the weaving machine and feeds the pressure value P back to the controller through the electronic signal, and the controller compares the actual pressure value P with a set pressure value W of the weaving machine to control the air compressors. The independent air supply device has the advantages that long-distance pipeline transportation is eliminated, and each air supply device can be independently set; the pressure sensor is arranged in the pipeline, working conditions of the air compressors are adjusted in real time according to requirements, and heat loss caused by high-pressure air is avoided.

Description

A kind of independent gas supply device and using method

Technical field

The present invention relates to a kind of independent gas supply device and using method, relate in particular to a kind of independent gas supply device and using method for air-jet loom.

Background technology

The required air pressure of air-jet loom is generally below 0.5Mpa, and central gas supply in the past, is mainly made up of air compressor machine, cold dry device, air accumulator, conveyance conduit etc.First will be through air compressor machine output squeezing air, pressure rises to 0.6～0.8Mpa, near pipeline is delivered to its air-jet loom, is connected with loom by flexible pipe, is then down to required air pressure through each function pressure-reducing valve and supplies with each functional part.More than compressed air process, in a series of course of conveying, first boost, along with the rising of gas pressure, a part of mechanical energy changes into heat energy and discharges into the atmosphere; Pipeline through long-distance is carried, and pipeline also will consume part energy to the obstruction of gas flow; Terminal device reduces pressure gases at high pressure by pressure-reducing valve, also can lose part energy.So central gas supply energy loss in multiple links of whole gas course of conveying is more.And tubing complexity, make troubles for Maintenance and Repair, increase maintenance cost.

Summary of the invention

For overcoming the deficiencies in the prior art, the object of this invention is to provide a kind of independent gas supply device and using method, reduce the energy consumption of air-jet loom air feed, reduce maintenance cost.

For achieving the above object, the present invention is achieved through the following technical solutions:

A kind of independent gas supply device, comprise several air compressor machines, pipeline, pressure sensor, controller, the delivery outlet of several air compressor machines is connected with same pipeline, directly enter loom gas storage bag, loom gas storage is wrapped and is provided with pressure sensor, pressure sensor is connected with controller, and pressure sensor feeds back to controller by the force value of loom gas storage bag by electronic signal.

A kind of using method of independent gas supply device, pressure sensor records the actual pressure value P at loom air inlet place, and pressure value P is fed back to controller by electronic signal, controller carries out compared with control air compressor machine according to the pressure set points W of actual pressure value P and loom:

When actual pressure value is less than setting value 95% time, i.e. P < 95%W, air compressor machine full power operation;

When actual pressure value setting value ± 5% in time, i.e. (W-W*5%)≤P≤(W+W*5%), air compressor machine is switched to low cruise state;

In the time that actual pressure value exceedes setting value 5% and is less than 10%, i.e. (W+W*5%) < P < (W+W*10%), close a part of air compressor machine, remaining air compressor machine continues low cruise, until actual pressure value setting value ± 5% in, i.e. (W-W*5%)≤P≤(W+W*5%);

When actual pressure value exceed setting value 10% time, i.e. P >=(W+W*10%), all air compressor machines are out of service.

Compared with prior art, the invention has the beneficial effects as follows:

This device is arranged on loom side, is connected with loom by flexible pipe, has saved the pipeline of long distance and has carried.This device output pressure is low, can every setting separately.Wrap pressure sensor is set in loom gas storage, the electronic signal of feeding back by pressure sensor and setting air pressure contrast in real time, adjust in real time as required the duty of compressor, avoid pressure-air to produce thermal loss.And directly entering the built-in air accumulator of loom from the compressed air of air compressor machine generation, length of pipe is down to the shortest, reduces the energy loss of compressed air along journey.
