San Lucas Sacatepéquez Installation of low temperature freezerProvide natural gas supply guarantee
The equipment is built according to the application requirements of low-temperature distribution. It is reflected in the following points: a low-temperature hall, a closed platform, an electric sliding refrigerated door an anti-collision flexible seal, good permeability to water vapor and a platform height conditioning equipment (lifting channel) are built to complete & ldquo; Door to door & rdquo; Type loading and unloading operation has become a symbol of modern cold storage.Watertight polyurethane rigid foam has low water absorption, and state of foam pores. It is not connected with each other, and the obturator rate is more than %. It is a dense microporous foam material, which is more dense than the surface of the air, and is not easy to permeate. It is an hydrophobic material.San Lucas Sacatepéquez ,The electrical contacts shall compress the wire connector and the main wire connector of the motor, which shall be clamped with a wire clamp, and tin shall be hung if necessary.According to the size and nature of the cold storage area and in combination with local regulations, the construction form of food cold storage warehouse is to determine the plane layout based on the site, whether it is a single-layer or double-layer warehouse, and the structure is the selection of steel structure or reinforcement solidification. Cold storage capacity, production process, refrigeration, product stacking, temperature, etc. are used to determine the size and location of the cold storage room, so that it can become a whole.Zaventem,The butt joint between the top warehouse plate and the end of the top warehouse plate shall be treated to prevent air leakage and cold running. After all the top warehouse plates are installed the butt joint shall be filled with foaming material, and the mm wide color steel plate shall be sealed at the butt joint with pull riveting.Cold storage has good fire and flame resistance. After adding flame retardant, polyurethane is a kind of flame retardant and self extinguishing material. If it is burned by fire, it can be carbonized, unlike flow burning and flashover like extruded board, it can be closed as a whole after fire prevention treatment to form non combustible products.Insufficient refrigeration dose and capacity in the system: there are two main reasons for insufficient refrigerant circulation,
The construction structure of structural cold storage can be brick concrete structure or steel structure, which can be determined according to their own budget and actual needs. At present, most cold storages are constructed with single-layer steel structure, and are equipped with combined thermal insulation storage body, unloading platform, refrigeration system, system, pipeline system, etc. according to the actual needs of cold storage circulation.After evacuation, medium and large cold storage is different, which is closely related to the purpose, otherwise the temperature in the cold storage often fluctuates frequently due to poor insulation performance, which affects the quality of stored goods. So, what is the difference between the ground insulation of small, medium and large cold storage? How to do better?new product,Compression refrigerator is commonly used, which is mainly composed of compressor, condenser, throttle valve and evaporation pipe. According to the way of evaporation pipe device, it can be divided into direct cooling and indirect cooling. Direct cooling the evaporation pipe is installed in the refrigerated warehouse. When the liquid coolant passes through the evaporation pipe, it will directly absorb the heat in the warehouse and cool down.The product shade warehouse is a warehouse location below ℃ and the sun cannot be straight. The humidity is % ~ % relative humidity, and there are corresponding strict requirements for the wall, ceiling, ventilation, disinfection and epidemic prevention of the warehouse. The refrigeration system adopts full-automatic microcomputer electrical technology and does not need to be on duty. It mainly stores western and Chinese grass materials and instruments, and can monitor and record the temperature and humidity in the storage area.The physical properties of polyurethane insulation board are relatively good which can meet different needs. The polyurethane insulation board is also strict in the selection of materials. It is a special product manufacturing enterprise integrating R & D, and service. It has long been specialized in cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage and medical cold storage. It improves the overall performance of the polyurethane insulation board and enables the polyurethane insulation board to work for a long time, Polyurethane insulation board has also become one of the main exterior wall materials.
Strong deformation resistance, not easy to crack, smooth, stable and safe. Polyurethane material has stable porosity structure and basically closed pore structure. It not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption performance. Under normal service and maintenance conditions, the life expectancy of rigid foam polyurethane insulation can reach more than years. During the structural life period, it can reach the unit price of dry, wet or electric corrosion under normal service conditions, while the unit price of insect, fungus or algae foam material is higher than other traditional insulation materials, but heating will increase the cost and the cooling cost will be greatly reduced.Create brilliance,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.During the welding of refrigeration pipeline, a blowdown outlet shall be reserved to blow the sewage from high and low pressure with nitrogen in sections. After the sectional blowing is completed, the whole system shall be blown until no dirt is found. The blowdown pressure is .MPa.At ordinary times, users should check the sealing degree of the gap of the cold storage, and notify the cold storage for maintenance in time if damaged parts are found.San Lucas Sacatepéquez ,Disadvantages of single-layer cold storage: large; The surface area of the external enclosure structure of the cold storage is large, so the amount of thermal insulation materials is large, the floor anti freezing treatment requires a large amount of work. When the cold storage is built at the water level, it is impossible to deal with it, which is easy to cause horizontal freezing and swelling.These measures have achieved quite good results. Compared with several cold storages at a customer in Jining,San Lucas Sacatepéquez Medical instrument cold storage, the cold storages using their white materials have significantly lower power consumption than those using other white materials.The type of cold storage to be built in the type of cold storage should be determined according to the type of circulating goods. For example, the cold storage that only circulates vegetables can only build a fresh-keeping cold storage, it should be determined according to the type, quantity, frequency,San Lucas Sacatepéquez Quotation and installation of cold storage, cycle, whether to use shelf stacking and so on. For example, for fruits and vegetables packed in cartons, the storage capacity of -kg per cubic meter can be referred to, and the size of cold storage construction can be estimated in combination with the storage capacity rate of about .-..
