the size changes often reflect bubble cracking or falling off, and these will inevitably affect the normal use of cold storage. In addition to regular simulation of performance testing, more emphasis is placed on the selection of high quality materials: special energy polyether compound use, so that the foam body mesh structure, greatly improving the foam low temperature resistance. At present, polyether commonly used in spraying materials contains a large number of functional components, and a large number of linear structures formed after reaction are difficult to be stable at low temperature; The use of the energy crosslinking agent also greatly improved the dimensional stability of the foam. The selected polyether adopts catalysis in the production stage and the reaction is complete, so that the polyether maintains a high reaction rate (that is, it can react completely with black material); Some manufacturers in order to achieve foam appearance does not produce deformation phenomenon and add a hole component to foam material, reduce the bubble closed hole rate, achieve the effect of stable size, but it has sacrificed the thermal insulation performance of polyurethane cold storage insulation material foam.The construction of cold storage in site selection bears the circulation of low-temperature goods. Therefore, the transportation convenience of cold storage construction site should be given priority in site selection, such as proximity to roads, railways, etc. At the same time, the location of the cold storage should avoid large pollution sources and direct sunlight, and the construction of the cold storage should have good drainage and ventilation conditions.San Rafael,Clean the bearing and replace the oil in the centrifugal pump, and the vibration of the shaft.Installation of box and operating device: the design of box shall be reasonable,San RafaelWhich specialty of cold storage installation, and the appearance quality shall meet the requirements of beauty and practicality.

The device box is installed on the door frame plate on the door opening side. The center line of the box overlaps the center line of the door frame plate. The bottom of the box is mm above the ground and is reliably fixed. The lighting lamp and door frame wire switch in the warehouse are installed directly below the device,The equipment configuration is reasonable and the service life of the quick freezing warehouse is long. The reasonable equipment configuration of the quick freezing warehouse can greatly prolong the service time of the quick freezing warehouse. Some compressors are easy to be damaged when they work at full load for a long time, so we try to use screw parallel units. The great advantage of this unit is that it can turn on all equipment, just like the shift at work, so that the compressor can work and rest in turn.It is strictly prohibited to place articles with pollution and peculiar smell around the cold storage. The surrounding environment of the cold storage must be cleaned and disinfected regularly every day,San RafaelCold storage installation engineering company, and the door of the cold storage must be locked.The equipment that needs to be installed in the warehouse and put into the warehouse shall be installed in place or placed in an appropriate position in the warehouse; The wall warehouse board shall be installed from the corner of the warehouse body, and the professional cold warehouse shall be installed. The cold warehouse shall be installed. The cold warehouse shall be constructed. The fruit fresh-keeping cold warehouse and medical cold warehouse shall have high pressure rating, good waterproof performance, fire and high temperature resistance, strong overload capacity, corrosion resistance, radiation protection and long service life. The corner shall be temporarily fixed with . color plate angle steel; When installing each wall panel, evenly apply two layers of foaming material on the joint surface of male and female groove, and apply one layer of foaming material when installing polystyrene wall panel. The blanking shall be uniform and continuous; After the wallboard is installed in place, pull rivets at the lap joint of the internal and external steel plates of the two wallboards for connection and fixation, the eccentric hook shall be loosened once before installation to ensure reliable locking during installation.

Features of quick freezing warehouse: the quick freezing technology is advanced, the frost free quick freezing method is adopted, the famous brand compressor and refrigeration accessories are configured, which belongs to the international advanced refrigeration technology in the st century.The warehouse shall be reasonably divided and set with relevant signs to facilitate the storage transportation and management of goods in the warehouse.The exhaust temperature of the compressor equipment is often. When the season changes and the temperature difference changes greatly, pay attention to it. If the machine is abnormal, it needs to be checked in time.High quality and low price, pay attention to whether the air curtain is opened or the door curtain is placed properly. Turn off the lights when leaving the warehouse.Polystyrene foam: polystyrene foam is a new type of synthetic thermal insulation material. It is a kind of plastic, with small density, light weight, strong heat insulation effect and excellent low temperature resistance. However, due to its cold shrinkage, it is not very convenient for installation.The polyurethane insulation board shall be connected by plug-in notch connection, because it has higher strength when connecting in this way.

If there is more air or refrigerant oil in the evaporator the heat transfer effect will be reduced: once more refrigerant oil is attached to the inner surface of the evaporator heat transfer tube, the heat transfer coefficient will be reduced. Similarly if there is more air in the heat transfer tube, the heat exchange area of the evaporator will be reduced, the heat transfer efficiency will be significantly reduced, and the decline rate of warehouse temperature will be slowed down.Market trend,Anti odor floor drain shall be set on the pavement of refrigeration room and refrigeration unit room, and the height width ratio of floor drain water seal shall not be less than mm. The elevator shaft, electronic pit and other places convenient for drainage shall be provided with drainage and equipment to avoid backflow of water.Check whether the compressor phase current is stable.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.San Rafael,During the installation of long-span top warehouse plate, if the supporting steel beam has been installed in the warehouse, the top warehouse plate and the supporting steel beam shall be fixed with pull rivets during the installation of each warehouse plate, and each top warehouse plate shall be riveted in two rows; If the lifting point type is adopted, the installation and construction of the lifting layout shall be realized before the installation and construction of the top silo plate, so as to ensure that each lifting point can be installed at the same time during the installation of the top silo plate; The lifting point shall ensure that there are at least two points along the width direction of each warehouse plate.The closed cell structure and surface material of polyurethane rigid foam with good moisture-proof, waterproof and corrosion resistance make it have better air resistance and water vapor resistance, and it can be made into inlaid connection structure during forming, which is easy to assemble. It does not need additional insulating layer to prevent moisture and saves a lot of trouble in laying insulating layer.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.
