Screw type air compressor use matters needing attention

1the correct installation of screw air compressor

The correct installation of compressor to ensure the compressor according to the design parameters, such as not installed properly, will lead to high exhaust temperature of compressor, vibration, a series of problems such as the abnormal sound.

The air compressor is installed on firm ground, using C20concrete equipment foundation. In the air compressor plant air compressor inlet gate of each of the walls of the elevation of016m are respectively arranged at the two axial flow fan, air intake grid air velocity is less than 015m / s, and the design of the inlet axial flow fan ventilation fan and compressor air coincide, ensure smooth ventilation system.

To ensure that the cooling air duct in the air pressure drop is less than 30Pa, designed to ensure that exhaust air from the compressor outlet pipe cross-sectional area is the top cross-sectional area of the compressor 2to 3 times. And the ventilation pipeline without necking. The other type screw compressor, such as the cooling air duct in the air pressure drop exceeds30Pa, should be in the cooling duct outlet installation of ventilation fan, can ensure the compressor outlet temperature control in the normal range. Air compressor of the ventilation system in initial operation stage of emergence of exhaust temperature up to 108 ℃phenomenon, by searching the reason analysis, because in May the air tree hair more, blocking the plate fin heat exchanger, affects the tone and the heat transfer effect.

In order to prevent tree wool clogging of plate-fin heat exchanger, the two axial flow fan of the entrance were added60to the stainless steel mesh, the effect is very obvious. In addition, after the operation, do regular purging of plate-fin heat exchanger, later did not appear the phenomenon of high exhaust temperature.

2adjusting screw type air compressor

Setting reasonable parameters after debugging installation of compressor, compressor, the correct and reasonable set compressor plus, reducing pressure and hourly motor start times is to guarantee the normal air compressor for the basic guarantee. In addition, to set a reasonable loading time, the motor start times can prevent compressor for a long period of time in the big car Mara state. Correct installation and debugging of the equipment at the compressor, high efficiency, stable operation state, prolong the service life of the equipment. According to the device for wind load requirements, design pressure is 612Bar, reducing the load pressure of 8Bar. from commissioning run to now situation, this setting can ensure normal operation of the device, especially to meet the cryogenic apparatus instrument air demand.

3maintenance and maintenance

Strengthening daily maintenance and maintenance of equipment operation, often need for equipment maintenance and maintenance, planned maintenance makes the compressor has the best efficiency, prolong the service life of the equipment.

(1) the timely replacement of lubricating oil. Lubricating oil in the oil jet screw compressor mainly from three aspects of the role of:

Lubrication, lubrication bearing, gear and screw;

The cooling effect, the rotating part in running the heat generated in the process of timely;

Effect of sealing, so that the output air pressure.

Therefore, to ensure the normal operation of transmission system is the key to quality of lubricating oil. Equipment manufacturers recommend the use of special lubricants, in order to protect the motor direct driven screw system. Its special formula in order to ensure its performance fully, the movement to extend the service life of parts. At the same time, a unique formula to ensure the favorable oil gas separation properties, lubricating performance, prevents the carbon deposition and excellent heat radiation performance. The use of special lubricating oil can make the moving parts replacement cycle extension, from the 2000h extension to the4000H, thereby saving cost. According to statistics, pay attention to lubrication oil and the maintenance can be reduced to 50% of the rate of occurrence of failure. Lubricating oil of poor quality or the oil is not timely, can lead to the injection screw host anomaly and noise. On the surface of the screw air compressor of long-term carbon formation, can lead to severe damage of bearing, screw host. So, must be timely replacement of lubricating oil. In addition, motor grease will regularly added, each2000h, adding 15 ~20Rotoglide grease, prevent damage to motor.

(2) prevents motor. Motor is easy to cause the damage of shaft, gear break, will appear the phenomenon of the screw.

(3) the timely cleaning the air filter. GA37P 10screw compressor in the entrance air filter clean, can filter out the impurities in98%, the remaining 2% dust air entering the compressor. In the process of operation, the air inevitably there will be dust, fog, mist, oil mist inhalation, if the dust in the air and many impurities, not timely entrance filter, mist and dust combination, will plug the tooth transmission effect, influence. Mist inhalation of the organism, corrode parts. This type of oil-jet screw air compressor, the air of dust and oil pollution caused by contact, lubricating oil, lubricating oil quality to drop, affect the bearing lubrication, thereby affecting the entire transmission system.

(4) periodically check the compressor is run, run, drip, leak phenomenon. Regular inspection of automatic condensate drain valve is smooth, liquid discharge is normal, to ensure that the export gas separated in time to drain away water.

4common fault

Annular valve common faults of air compressor air valve is the most important and most vulnerable part, usually caused by air compressor valve fault is the main reason of unplanned downtime. Compared with air compressor components, valves are the most sensitive, which directly affects the air compressor running economy and reliability. Therefore, the relevant design documents and procedures are required to conduct regular check and repair the valve, in order to minimize valve failure.

Valve in the gas flow velocity, valve lift, spring force on its condition has a direct impact, annular valve common fault:

The 1 valve seat, valve plate sealing edge wear and the gas valve gas leakage is generated;

The 2valve body cracks and even fragmentation makes valve failure;

3valve spring elastic force makes the valve loss generated in the work of serious percussion, lead to valve earlier damage.

Wherein, valve fragmentation will produce the most serious consequences. Fragmentation of the valve seat, valve plate, a center bolt into the cylinder will cause air compressor cylinder bump accident, hit will cause the cylinder piston, cylinder, piston rod, cross the first a series of mechanical damage.

Reminder.

Screw air compressor air compressor supporting" and" water heater, not only without any cost to gain life and industrial water is also beneficial to the screw air compressor maintenance and maintenance, for your business to save a lot of money.

Screw type air compressor maintenance daily maintenance item

1, check the air filter and coolant level;

2, check the hose and all the fittings have leakage;

3, inspection records, if easy consumption has to replace the cycle must be shut down to be replaced;

4, inspection records, when the exhaust temperature is at or near the98C, must wash oil cooler;

5, check the condensed water discharge, if it is found that the displacement is too small or no condensed water discharge, must stop cleaning water separator.

Monthly maintenance item

1, check the oil cooler surface, necessary cleaning;

In 2, after cleaning the cooler;

3, check all wires are connected and fastened by;

4, cleaning motor suction opening surface and the surface of the shell of dust;

5, clean oil return filter.
