When opening and drilling is required for the top warehouse plate or wall plate, the internal and external setting out and positioning shall be carried out according to the drawing design requirements and the opening and drilling shall be carried out after review; The inlet hole, liquid inlet hole, return hole, water supply hole and drainage hole shall be opened with a hole opener. Construction treatment shall be carried out in time after opening and drilling, and the orifice shall be closed with foaming material or sealant to prevent air leakage and cold running; The door, vent and delivery port shall be decorated with wrapped edges and fixed with pull rivets, with a spacing of mm and mm outside.For the flushing (thawing) drainage pipe in the cold room with different temperature, an exhaust valve equipment shall be set before connecting the flushing (thawing) drainage pipe.St. Thomas,The electric cabinet shall be in strict accordance with the requirements of the drawing, and the power shall be connected for no-load test.During the production of cold storage, the cold storage will produce fixed length, width and thickness according to the needs of various cold storage projects. Generally, cm thick cold storage plates are selected for high and medium temperature cold storage. The requirements for cold storage engineering plates of low-temperature storage and quick-frozen storage will be higher. Professional cold storage installation, installation, construction, fruit fresh-keeping cold storage and medical cold storage ensure the quality, Guarantee service. Guarantee quality. Your satisfaction is our pursuit! Welcome to inquire. In this case, use cm or cm thick library board. When you budget the cold storage project, you can make a reservation according to the specific conditions of your cold storage temperature. If you don't make a reservation for the cold storage plate, you should pay attention to the density of the cold storage plate and the thickness of the steel plate when purchasing the cold storage plate. According to regulations, the foaming density of cold storage is per cubic meterAntsohimbondrona,Disadvantages of multi-layer cold storage: the vertical transportation volume of the warehouse is large, and the goods in and out and operation management are not as convenient as single-layer cold storage; With the development of the floor load capacity the floor area ratio of each cold room is low; When the multi-storey cold storage is built on the foundation with poor ground resistance, large construction equipment is required and the construction period is long.Kg to kg / m, and the steel plate thickness generally needs to be more than . mm to meet the standard. On the market, the main raw materials of special cold storage board for cold storage project are polyphenylene, polyethylene and polyphenylene grease. The density of thermal insulation material foamed by polyphenylene is thin, it can foam cold storage insulation materials with appropriate density and good thermal insulation effect, and has high load-bearing capacity; Polyphenylene resin has strong water absorption, but poor heat insulation. Therefore, the polyurethane sandwich board with very good performance belongs to the polyurethane sandwich board. Although it is slightly higher, the polyurethane board has very good thermal insulation performance and does not absorb moisture.Fault phenomenon: fan motor overload, fan deformation; Fan motor fault; Fan motor thermal relay fault (aging); Loose wiring; Cooler blocked; Large exhaust resistance. Cold storage fault phenomenon: dryer does not operate, compressor line is disconnected, fuse is blown, thermal relay acts, high voltage switch acts, compressor is locked, line is falsely connected or loose fault phenomenon: it stops in a short time after drying, condenser is blocked
In order to maintain a constant low temperature in the cold storage, attention should be paid to the installation of cold storage panels in Guizhou: the floor, wall and flat roof of the cold storage are laid with a certain thickness of thermal insulation materials to reduce the incoming heat from the outside. In order to reduce the absorption of solar radiation the surface of the external wall of the cold storage is painted white or light color. Therefore, cold storage building is different from general industrial and civil buildings, and has its unique structure. Cold storage buildings should prevent the entry of air and the diffusion of water vapor.Good heat dissipation, good refrigeration. Do not stack sundries around the refrigeration unit The electrical equipment of the fresh-keeping warehouse equipment shall be protected from moisture and electric shock caused by electric leakage. The hinge, handle and door lock of the fresh-keeping storehouse shall be regularly added with oil according to the actual situation. The electrical equipment maintenance of the fresh-keeping storehouse equipment shall be operated by electricians or personnel who know the common sense of electricity. Any maintenance must cut off the power supply to ensure safety.The evaporator surface is too thick or too much dust, and the heat transfer effect decreases: another important reason is that the heat transfer efficiency of evaporator is low, which is mainly caused by excessive frost or excessive dust on the evaporator surface.build,Able to withstand the harsh local climate and its changes. Neither high temperature nor severe cold climate will cause irreversible damage or deformation to the external insulation system. The drastic change of the surface temperature of the external wall, or shading during exposure, will not cause damage to the surface of the cold storage.. Maintenance of food cold storage. In a position convenient for operation outside the door of the refrigerator room, a main switch for cutting off the power supply of the refrigeration compressor shall be set. This switch shall be able to stop the operation of the refrigeration compressor, and relevant signs shall be set. If the mechanical panel is set in the main room, a button switch shall be added next to each refrigeration compressor.Install the temporary lighting facilities in the warehouse, install and arrange the construction electrical equipment, and do a good job in rain proof, moisture-proof, anti-collision, anti binding and other safety protection.
Some cold bridge prevention measures shall be taken at the joints between polyurethane insulation boards.Finance Department,Other aspects: in the design process of food cold storage, it is also necessary to consider the cooperation between the cold storage and on-site fire fighting ventilation, water and electricity systems. It should meet the requirements of safety, the drainage problem must be considered and the following points should be paid attention to during redesign and installation.According to the technical requirements for the installation of cooling fan, when selecting the lifting point position, the position with good air circulation shall be considered first. Secondly, the direction of library structure is considered.Establish a perfect computer network, make the distribution of refrigeration supply chain scientific, and achieve the traceability of food safety. In the European Union, the United States and Japan,St. ThomasSmall installation of freezer, all members of the food supply chain have the legal responsibility to implement traceability.St. Thomas,After the cold storage at the corner is installed, the next cold storage can be installed along the direction of the corner. Adopt the similar installation of Zhang cold storage to install the thermal insulation board of the storage. Professional cold storage installation, installation of cold storage, cold storage construction, fruit preservation cold storage, medical cold storage,St. ThomasHow much is the construction and installation cost of cold storage, advanced technology, strict testing, more affordable price and more preferential. Welcome to consult. Pay attention to its compactness and continuous uniformity.When installing polyurethane insulation board, ensure that its surface is smooth and flat without scratch and warpage.During the early operation of the refrigeration unit, carefully observe the oil return of the compressor and keep it clean. If it is found that the oil level is not clean enough or the oil level drops, replace it with new oil in time, so as to avoid bad compressor and reduce the service life of the compressor.
