Description

THE COOLER WITH THE CLOSED CONTOUR
COOLINGS OF GZK - 3

Appointment. The cooler ventilatory with the closed contour is intended for liquid cooling (the prepared (distilled) water, oil, aqueous - alcoholic solutions, etc. ) circulating in the closed contour without rupture of a stream and loss of working pressure.

The cooler with the closed contour has two independent contours: "processing equipment - the cooler heat exchanger" and "the water - collecting pallet of the cooler - water distribution system of the cooler" that prevents a possibility of evaporation and mixing of the cooled liquid with the cooling reverse water.

In the top part of the cooler the water distribution system providing uniform distribution of the reverse cooling water on an external surface of pipes of the heat exchanger is located. Heat from the cooled liquid is transmitted through walls of pipes of the heat exchanger in reverse water. At the same time reverse water partially evaporates. Flowing down from system of pipes of the heat exchanger reverse waters gathers in the pallet from where by means of the pump moves in water distribution system.

Feed of the evaporated amount of water is carried out automatically, by means of the valve with a float.

The stream of air promotes intensive evaporation and according to cooling of reverse water. Thus, heat passes from reverse water into the circulating air.

Design features of the cooler GZK - 3

Cooler case The bearing system of the case of the cooler consists of steel galvanized structures.

The covering is made of profile galvanized sheets with a polymeric covering or PVC of sheets which fasten to a metal galvanized framework.

In the lower part of the cooler the water - collecting pallet is placed by V=7m3 volume.

Cooling system Represents the heat exchanger from the thin - walled metal tubes processed by method of hot galvanizing, or copper tubes. The heat exchanger is in the cooler case.

Thanks to a simple design of the cooler there is a possibility of bystry dismantle of the old module of the heat exchanger and installation new.

Water distribution system It is intended for uniform distribution of reverse water on a surface of pipes of the heat exchanger for an intensification of process of a heatmass exchange and consists of plastic pipelines and nozzles.
Water catcher It is placed directly over water distribution system of the cooler and intended for catching of the drops of water taken by an air stream in a heat exchanger zone.
Ventilatory installation Is in the top part of the cooler. Ventilatory installation provides the compulsory movement of air. The pryamoprivodny single - speed electric motor, the driving wheel with plastic blades and the diffuser is a part of ventilatory installation.

The used fan is characterized by the low noise level, durability and simple technical leaving.

Control system and control with the frequency and adjustable drive of the electric motor Provides:

1. Conclusion to the front panel of a case of management of light indication of the working condition: networks; pump; ventilatory installations; systems of feed.

2. A conclusion to the front panel of a case of management of emergency light indication of low water level in the cooler pallet for operation of the pump.

3. The sound alarm system at:

  • pump electric motor overheat;
  • low water level in the cooler pallet;
  • at fall of temperature of water in the pallet of the cooler the factory setting / is below + 15 °C/.

4. Manual inclusion / switching off of ventilatory installation.

5. Automatic control of frequency of rotation of the electric motor depending on temperature of atmospheric air.

6. Automatic inclusion / switching off of work of system of feed.

7. Automatic shutdown of the pump at an overheat or abatement of the water level in the pallet below the minimum level, and also automatic inclusion at restoration of the above - stated parameters.

Possibility of information output on the top level by means of standard protocols and ranges of signals.

Circulation pulser Is established on the soaking - up pipeline for water supply from the cooler pallet on a water distribution irrigation system of the heat exchanger. On the soaking - up pipeline the filtrational grid for prevention of absorption of rough particles of pollution in the pump is placed

Feed of the evaporated amount of water is carried out automatically, by means of the electromagnetic valve with a float.
