The Method Of Realizing Energy Saving By Air-jet Loom

Shuttle looms are mainly woven loom, Water-jet loom, Air-jet loom, rapier loom. Among them, the Gripper loom Unit energy consumption (in weaving per square meter cloth calculation) Lowest, water jet loom second, jet and rapier loom highest. Enterprises to buy which loom can not be used only as the main indicators of energy consumption, but textile machinery factory in the introduction of new machines must pay attention to energy-saving technology.
 The high energy consumption of Air-jet looms is mainly in the energy consumption of nozzles. The jet loom manufacturing enterprises have studied the nozzle holes of the auxiliary nozzles very early, using the shape of single hole, porous and inverted cone, many of them have been applied in practice, and the auxiliary nozzles with various aperture shapes have their advantages. Innovations in the nozzle (including the main and auxiliary nozzles) and the trachea not only save energy but also improve the quality of weft insertion.
With the electronic technology widely used in the loom monitoring, monitoring, enterprises have successively introduced new energy-saving new technologies and measures, such as the application of auxiliary nozzle solenoid valve of Air-jet loom from the past $number only auxiliary nozzles are configured with 1 solenoid valves to 2 auxiliary nozzles configured with 1 solenoid valves, controlled by an electronic control box for an ordered switch of the solenoid valve to achieve the purpose of the Airflow relay jet. It is said that only this new technology can save air consumption $number. For example, the Air-jet loom of 4750px Reed 1 Air-jet loom weft gas consumption is 0.5 ~ 0.6 cubic meters/min, 48 Air-jet Woven confidential configuration nearly 40 cubic meters/min of air compressors, while 1 40 cubic meters/min compressed air to configure 1 Tens watts of motor. General 4750px Air-jet Loom has 24~26 only auxiliary nozzle, in the weft insertion channel each auxiliary nozzle spacing has 70~80mm, because $number only auxiliary nozzle configuration 1 solenoid valve, namely $number auxiliary nozzle switch time is simultaneously, this cannot save the gas consumption. Now some Air-jet loom 2 auxiliary nozzle configuration 1 solenoid valve, only 2 auxiliary nozzle switch time is the same, this creates the condition for saving the gas consumption. With the increase of loom speed and the reduction of each solenoid valve control auxiliary Spray Quantity, it is required that the auxiliary nozzle speed is accelerated and the technology without high performance and high speed solenoid valve cannot be popularized.
In addition to the energy consumption of air weft insertion in looms, other organizations are also consuming a great deal of power, the most important of which is the weft-playing mechanism. There are two kinds of beating mechanism: crank linkage and conjugate cam, both of which have their advantages and disadvantages. More than 20 years of production practice contrast: These two types of weft-playing mechanism are in line with production requirements. For the individual heavy-width fabric, the conjugate cam-weft-insertion mechanism has its outstanding advantages, while the crank-connecting-rod-beating mechanism is deficient in this aspect. For the vast majority of products, the two institutions are exactly the same. In terms of quantity, the application of crank linkage is an absolute majority in Air-jet loom. The rapier loom is developed from the crank-connecting-rod mechanism to the conjugate wheel-beating weft mechanism. And the gripper loom is not a conjugate cam mechanism.
The second is the opening mechanism. Whether the cam openings or dobby openings are energy-consuming institutions. But the same is the cam openings, the negative cam energy consumption is slightly lower than the active cam. Two kinds of cam openings have advantages and disadvantages, users should be in accordance with the specific conditions to buy. The energy consumption of dobby is larger than that of cam openings. Japan's Toyota and Tsuda colt companies have launched 1 of the 1 servo motor of the electronic Dobby, the cancellation of electromagnetic iron, cam, energy consumption than the existing electronic dobby and much lower, the adjustment is also very convenient.
When it comes to Air-jet looms, air compressors cannot be mentioned. Now domestic enterprises use the air compressor is not very ideal, the compressor efficiency is low, and because the vibration and noise are relatively large, the compressor should be installed in the distance from the Jet loom workshop, so the pipeline energy loss is very large. Japanese Air-jet looms use small capacity of the air compressor, such as 48 Air-jet loom use factory only with 4 small capacity of air compressor, 3 units often open 1 standby, and standby is not always to stop using instead of 4 devices in turn to rotate the boot. It is installed not far from the loom, some even in the production workshop. From this point of view, energy consumption is certainly lower than ours.
Air compressor is divided into absolute oil and oil filtered by the two indirect oil. Oil-free compressor from the operating efficiency, life, energy consumption is better than absolute oil. Before 20, enterprises were using absolute oil-free compressor. In recent years, many users have switched to oil-free compressors, and its price is much cheaper than the absolute oil-free compressor. and the oil air compressor after continuous groping to improve, the first is to change the lubricating oil varieties, the use can be cleaned in addition to oil stains, in case the filter failure, oil spills in the finished cloth, can be processed in the process of dyeing and finishing to eliminate. There is a shortage of oil air compressor, its lubricants have a certain service life, to be replaced regularly. At the same time, filter oil network should be cleaned or replaced regularly.
In recent years, the air compressor factory also introduced the electronic control of variable-frequency motor, stepless variable speed air compressor, according to the introduction can save about 10% of energy. It is energy-saving because it can adjust the speed of the motor according to the size of the gas consumption. Take 96 Air-jet looms as an example, the general situation of gas supply is greater than the consumption of gas, because 96 loom there are always several downtime, although there is a gas tank can regulate the volume, but if the loom stop more than the air compressor is full, and the compressor will be shut down, and centrifugal air pressure shutdown after 30 minutes to reboot, do not allow time to stop, open. So there is a way to take no downtime, so a part of the energy is wasted. This energy-saving air compressor can solve the problem of emptying, thus saving energy.
