To introduce to you about the cold storage insulation board cold storage debugging and structure of the problem

Cold storage insulation board cold storage system debugging after installation should pay attention to the problem

Cold storage insulation board cold storage debugging, to do a good job in the air conditioning unit internal cleaning and drying work, if you do not pay attention to the early stage of the project, in the adjustment period may increase a lot of labor, the follow-up operation of refrigeration equipment will produce a lot of security risks, here, on the freezer after the installation of the system software adjustment, the overall should pay attention to what topics?

1. Confirm whether the gate valves of each part of the freezer unit are in all normal open conditions, especially the exhaust pipe should be turned off and cannot be turned off.

2. Open the cooling circulating water gate valve of the cooler and the cold water gate valve of the air conditioner evaporator. The total flow of cold water and cooling circulating water should meet the requirements of the factory.

3. Before running the cold storage, pay attention to observe whether the working voltage of the power supply system of the generator set is all normal.

4. Run the generator set in accordance with the start-up instructions provided by the manufacturer.

5. After the cold storage generator set is running, according to the boot guide prompted by the manufacturer, check whether all the main parameters of the generator set are normal.

6. According to the operation data information record card of the screw type cold water generator set prompted by the factory, various data information of the screw type cold water generator set can be recorded, especially some basic parameters need to be recorded clearly.

7. In the whole process of the operation of the screw-type cold water generator set, pay attention to whether the upload and free download organization of the refrigeration compressor are all operating normally.

8. Properly apply the safety protection equipment installed in the cold storage, such as high-pressure and low-pressure protection equipment, cold water and cooling circulating water cut-off flow switches, valves and other mechanical equipment. If there is any damage, it should be removed and replaced in time.

9. If the screw-type cold water generator set is found to be abnormal, it should be immediately cut off for inspection.

If there is a problem with the installation structure of the cold storage insulation board, how to deal with it.

As we all know, the installation structure of the cold storage includes the basic, wall and beam, plate and column load structure. When the component is cracked, the support point, repair, structural reinforcement or overhaul shall be carried out according to the situation. The maintenance of the cold storage installation structure is basically consistent with the industrial building, but the difference is the following three levels.

1) the vibration bearing structure crack is not big, no longer have the development trend, the crack should be cleaned, with hot asphalt, paint or epoxy resin for blocking repair, can be applied again.

2) After the proliferation structure is strengthened, due to the independent expansion, the compression strength has also changed to a certain extent, so the setting of the cold storage should be clarified again according to the specific bearing capacity.

3) Regarding the cracks in the wall surface, it is first necessary to investigate whether the cause is the basic ground settlement, or the engineering building materials are not good, or the engineering construction is not carried out in accordance with the regulations, and then the solution is clear according to the damage level. If the total width of the cracks cannot reach the gas barrier layer, the cracks can be embedded in artificial epoxy resin. After asphalt, the surface is received with cement mortar, and then reinstalled on the refrigerator, if the waterproof gas barrier layer is damaged and there is a trend of further development, certain effective measures must be taken to carry out overhaul and solve the difficulties from the source.
