to hobby diving presents no surprises, but gave only a pleasure, it is necessary to follow strict rules of preparation to dive into the water.Correct filling oxygen cylinders - this is one of the most important, but the danger of the preparation procedures.
tanks cylinders can fill ordinary air or special gas mixture pumped into them by means of a compressor.At high pressure, the depths of impurity in gas mixtures can be life-threatening, so filling cylinders with compressed gases should be excluded altogether.
fill with oxygen cylinders should be only in specialized areas, for example, where the selling scuba equipment.Tucking oxygen cylinders, you must consider a few important details:
- Be extremely careful when pumping oxygen.
- Use only labeled oxygen cylinders.
- Oxygen cylinders must be a pointer to the mixture composition.
Carbon and carbon monoxide gases, particles from oil and grease from the compressor and other impurities that can clog the breathing mix - they can cause the death of the driver.
reasons for the explosion of oxygen cylinder
working with oxygen at any moment explode oxygen cylinder, which causes may be:
- Corrosion of the inner wall of the container.
- Carelessness during pumping oxygen.
- damage the thread or the neck in the place in which the valve is mounted.
explosion of an oxygen cylinder can also be triggered by sudden changes in temperature and air tank being filled.The powerful compressor, forcing cold air, warms up the tank.After refueling, the metal part of the balloon cools faster than the hot air trapped inside it, and this, in turn, produces additional stress on the walls of the tank.
It is during this critical voltage, and there is a risk of explosion.Therefore, the process of cooling - this is the most dangerous moments of the process of filling oxygen cylinders.
Oxygen cylinders, it is desirable to keep tucked that perfectly reduces the risk of falling into the container of hazardous elements (particles of diesel, petrol, sea water, toxic gases, colonies of microorganisms), then threaten both life and health of the diver.
oxygen cylinders filling station
This station, as a rule, is composed of an oxygen concentrator with the necessary power connection fittings and high pressure oxygen compressor.For example, a complex which consists of an oxygen concentrator and a corresponding compressor performance which is 8 liters per minute at a pressure of 150 atm can charge two sorokalitrovyh cylinder per day.This complex can completely solve the problem of oxygen supply.For example, ambulance station.
oxygen concentrator improved performance when used with the appropriate capacity compressor can fill oxygen cylinders up to 100 pieces per day.
