Communicating Vessel Type Air-Lock  

I. Overview

GFL series is a new type air-lock, it adopts dual channel communicating vessel type structure form, different from traditional impeller type air lock device; its outstanding features and advantages: power consumption is about 10% of the impeller typeair lockof the original capacity.

GFL series air lock offers 5 specification types,  i.e. 9L,12L, 16L, 25L, 40L. It may be divided into electric, pneumatic modes according to the drive mode, power is 120-220W. It has been used extensively in building material, food, grain, fodder and other industries.

II.Operating principles

This air lock has two material channels, adopts a structure similar to the ship lock connector type structure at Three Gorges Dam. Two channels feed and discharge materials in turn, ends of the channels are connected in series for circulation purpose, so as to realize material discharge requirements in a sealed manner.

III. Equipment features

1. The product has obtained national patent for invention, could save energy up to 90-95%, its power is low, power of the largest motor is 180W, compressed air flow is 400L/h.

2. This series of equipment is driven by motor or cylinder; easy for installation and repair;

3. Interchangeable with traditional products of the same specification, the connection dimension, height dimension are the same.

4. Flexible seal; sealing element adopts food-grade material, could resist wearing, is easy for replacement. The seal is tight;

5. Complete variety; positive pressure blowing auxiliary system, motor anti-burnout auxiliary system, discharging speed regulating auxiliaries, metering auxiliary system and all stainless steel housing may be selected for different service conditions.

V. Installation, operation and maintenance

1. Installation and operation

A professional operator is required for the installation and commissioning, he shall check whether the material inlet/outlet is sealed well, whether the hopper is installed. Check whether motor line voltage is normal and check ground resistance of the housing; check whether sufficient lubricating grease has been filled before operation; check whether there is any abnormity after the motor starts; always stop timely for troubleshooting if there is any abnormity, so as to prevent unnecessary losses.

2. Maintenance

This equipment should be maintained according to general equipment maintenance management system, lubrication and operating conditions should be checked regularly, poor lubrication state or worn sealing elements must be treated timely to ensure the equipment in normal operating state.

In addition, in order to maximize the equipment value, regular patrol inspection or point inspection should be performed for the air lock device, hidden troubles that might influence the life ofair lockmust be eliminated.
