Briefly talk about the sealing of the refrigerating display cabinet refrigeration system!

First, the sealing requirements of the refrigerating display cabinet refrigeration system

After confirming that the refrigerated display cabinet refrigeration system is filled with refrigerant, and the compressor is stopped and the pressure gauge shows positive pressure, the refrigeration system can be sealed. If the pressure gauge shows a negative pressure, it means that the first sealing is not strict, so that the refrigeration system enters the air, causing the vacuum degree of the system to drop.

Second, the sealing method of the refrigerating display cabinet refrigeration system

Sealing when the compressor is stopped and the pressure gauge shows positive pressure:

In the first step, the pressure gauge and the repair valve assembly are selected as the sealing portion of the process pipe welding day about 4 cm.

In the second step, adjust the adjusting nut of the sealing pliers so that the jaws are the same as the outer diameter of the process tube, and the locking nut is screwed by hand;

In the third step, the outer flame of the neutral flame is used to heat the sealing part to dark red, which not only makes the sealing part soft and is favorable for sealing, but also thermally connects the sealing part of the inner wall of the copper pipe to improve the airtightness of the sealing;

In the fourth step, the position of the roasting red is clamped by a sealing pliers, and the pliers is pressed to lock the sun blocker;

Step 5, use a wire cutter to clamp the sealing position 5cm, and remove the pressure gauge and repair valve assembly;

Step 6, repair the nozzle with gas and silver electrode;

Step 7, after the soldering place is cooled, remove the sealing pliers;

In the eighth step, the pinch joint is welded, and the seal is filled with solder to enhance the sealing and firmness;

In step 9, seal the seal and the cut-off nozzle with soapy water;

In step 10, the thin copper tube is bent into a semicircular shape and is not allowed to collide with other piping to prevent it from colliding with the process pipe when the refrigerator is handled.

Third, the refrigerated display cabinet refrigeration system sealing notes:

1. When sealing, if the jaw of the sealing pliers is too small, the copper tube at the sealing part will be cut off or the sealing pliers will not be easily disassembled; if the jaws are too large, the sealing will be not strict, causing the refrigerant to leak. If the first sealing is not strict Immediately remove the sealing pliers. At the original seal, the gas is about 1cm. The third is re-sealed. If there is still a leak, the size of the jaws of the two double-sealing pliers.

2. When welding the pipe of the process pipe, put a piece of iron plate on the lower side of the process pipe to avoid roasting the cabinet or other parts of the refrigerated display case.

3, using R600a refrigerated display cabinet must be confirmed that the seal is not leaked before welding, in order to avoid danger.

Pet Quantum Analyzer


What is the pet scanner?

[Pet Scanner] involves high-tech innovation projects of medicine, bio-informatics, electrical engineering and other sciences. Using the quantum medicine as the theoretical basis, it applies the advanced electronic equipment to collect the weak magnetic field of animal cells for scientific analysis, thereby analyzing and determining the tested animal's health status and main problems and


putting forward standard prevention recommendations. [Pet scanner] is individualized guide of health care consultation for full animal body and forward health science, and has the advantages of completeness, non-invasiveness, practicality, simplicity, fastness, economy, easy popularization, etc. With the depth and development of scientific research, it will make a greater contribution for the cause of animal health, having a broad development and application prospect.

Principle of quantum analyzer:

The animal body is the aggregates of a large number of cells which are in continuous growth, development, differentiation, regeneration and apoptosis, and the cells constantly self-renew through its own division. In the process of cell division and growth, those charged bodies of atomic nucleuses constituting atoms as the basic unit of cell and the electrons outside the nucleus are in constant high-speed movement and changing, thereby constantly emitting electromagnetic waves.

The electromagnetic wave signals emitted by the animal body represent the specific state of the animal body, and the emitted electromagnetic wave signals are different under the different conditions of the human body, such as health, sub-health, disease, etc. If we can determine these specific electromagnetic wave signals, we can determine the status of the body's life.

Quantum medicine considers that the most fundamental reason of falling sick is that the spin of electrons outside the atomic nucleus and the orbit change, thereby causing the change of atoms constituting a material, the change of small biomolecules, the change of big biomolecules, the change of all the cells and finally the change of organs. Because the electron is a charged body,

when the spin of electrons outside the atomic nucleus and the orbit change, the electromagnetic wave emitted by the atoms will change. The energy o f the electromagnetic wave changes caused by the changes of the animal body's diseases and physical changes in the nutritional status is extremely weak and usually is only nano gauss to microgauss. The frequency and energy of the

weak magnetic field of hair determined directly or by holding a sensor compare with the resonance spectra of standard quantum of diseases and nutrition indicators set in the instrument after the frequency and energy are amplified by the instrument and processed by the computer, and then the corresponding quantum value being from negative to positive is output. The size of the

quantum value indicates the nature and extent of the disease and the nutrition levels. Finally, the test results are resolved by clinicians. It's similar to the principle of listening to broadcasting from the radio. There are many radio waves in the air. If you want to listen to some designated broadcasting, you can transfer the radio to the corresponding frequency, at this moment, resonance occurs, so that you can listen to this broadcasting. Quantum resonance uses this principle for testing.
