The site should be carefully checked for the chiller type and evaporator design pressure. It is not possible to use the water inlet as a water outlet and vice versa: the water flow switch is determined to be installed.

The first start-up must be carried out under the guidance of the chiller plant manufacturer's personnel. Do not power on the chiller without permission. The installation requirements of the chiller plant are reflected in the operating instructions and the chiller plant manufacturer's personnel will be sent to the site to guide the installation in liquid air separation plant.

 

Site of liquid air separation plant plan layout, piping system configuration in accordance with GB16912-2008 "Deep freezing method for the production of oxygen and related gases safety technical regulations" in line with GB50058-92 "design specifications for electrical installations in explosive and fire-hazardous environments" liquid level design, the

Liquid level regulator insulation: there should be steam or electric heating with heat insulation measures air-cooled tower, water-cooled tower inlet pipe should have a gas seal, in order to waterproof backflow, the height of the gas seal to the requirements prevail. Water pump inlet and outlet pipes set up the necessary support pipe frame to prevent vibration caused by the pump inlet and outlet flange pulling crack.

Air outlet pipe of liquid air separation plant: and pipeline welding must be primed with argon arc welding before welding, so as to avoid welding slag in the air cooling tower screen defoamer screen burned.

Dear air separation of the pipeline flaw detection technology: the use of non-destructive testing air pipeline welds ≥ 250mm, 100% ray inspection, in line with JB / T4730-2005 "non-destructive testing of pressure equipment" requirements, the rest for surface non-destructive testing, and in line with the JB / T4730 provisions of Class 1 requirements.

Sieve tray is one of the most widely used trays in air separation columns. Its main structure is that there are evenly distributed small holes with spacing of 2.1 ~ 3.25 mm and diameter of 0.8 ~ 0.13 mm on the tray. During the operation, the steam bubbling up through the liquid layer through the sieve hole, and the liquid on the tray can only flow in a fixed direction because it is held by the steam. The advantages of sieve tray column are simple manufacture and high efficiency. The disadvantages are that liquid may leak through the sieve hole when the load is too low.

What is the Air separation unit instrument cluster and what is the relationship between transmitters, display tables, regulators, and membrane control valves?Air separation unit.1 g potassium dichromate or 2 g sodium nitrite can be added to each liter of water (not suitable for nonferrous metal degreasing); due to the toxicity or explosion of degreasing agent, attention must be paid to prevent poisoning and formation of explosive mixture. In alkaline cleaning, the pipeline with more oil stains is heated to 60-90 ℃ with 10% sodium hydroxide solution, then neutralized with 15% nitric acid and washed with clean water.Air separation unit.From the vaporization temperature (saturation temperature) of liquid oxygen, if the liquid oxygen surface is too high, the greater the static pressure difference between the upper and lower liquid oxygen surface, the higher the average pressure of liquid oxygen and the corresponding saturation temperature. In order to maintain the heat transfer temperature
