Stretch perlite: stretch perlite is a kind of granular material with porous layout. The gap in it blocks out the heat. Professional cold storage installation, cold storage installation, cold storage construction fruit fresh-keeping cold storage, medical cold storage, strict testing, quality assurance. Preferential activities are in progress. Welcome to consult. It has a good heat insulation effect. Then, the water vapor in the cold storage is easy to condense, and the water absorption of extensional perlite is particularly strong. If it absorbs a lot of water its nature will be greatly reduced. Therefore, the transportation convenience of cold storage construction site should be given priority in site selection it is necessary to be careful to select extensional perlite as cold storage.The construction of cold storage in site selection bears the circulation of low-temperature goods. Therefore, 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.portland ,Due to the slow cooling, all equipment will consume electric energy during operation. If the cooling is slow, so the electricity charge will not be consumed. As a high energy consuming equipment, the daily power consumption of cold storage is relatively large. If the refrigeration effect is not good, the annual use cost will directly double several times. Moreover, if the equipment operates for a long time, the service life will be reduced accordingly, which is something users don't want to see.How to maintain the refrigeration compressor in the cold storage in order to prolong its service life and reduce the occurrence of faults in the use process. The refrigeration compressor in the cold storage needs regular maintenance. Here we introduce the maintenance of the compressor in the cold storage.In - Salah,The new cold storage material is made of rigid polyurethane or polystyrene foam insulation sandwich panel, which is made by high pressure foaming process and can be made into various lengths and specifications to meet the different requirements of the users.Various construction materials, such as material certificate, test report and stage acceptance record, shall be carried out simultaneously with the project construction, carefully,portland How much is the installation of fruit cold storage, timely, accurately and comprehensively reflect the whole process of production and construction, and actively cooperate with the owner in design change and technical negotiation.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, 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.

The bacterial action of acid disinfectants is mainly to coagulate the protein in the bacteria. Common disinfectants include lactic acid, bleach, formalin, etc. Specifically, after the fish comes out of the freezer, clean the frost layer on the evaporating pipe group and keep the storehouse temperature below degrees Celsius. Then, according to the volume of ~ grams per cubic meter volume of the frozen storeroom, the storeroom door is closed tightly with the sprayer,portland Well known cold storage installation company, and the blower is started intermittently, so that the vinegar evaporates and flows in the storehouse, it will affect the sealing performance of suction and exhaust valve plates and valve seats, which will seriously affect the refrigeration capacity of the controlled atmosphere storage.All wiring shall be neat. All switches and keys shall be opened and closed sensitively, reliably and accurately. Special connectors shall be used for wiring, and power protection shall be provided for the box and each power branch.quality standard,The product shade warehouse is a warehouse location below ℃ and the sun cannot be straight. The humidity is % ~ % relative humidity, ceiling, ventilation, and can monitor and record the temperature and humidity in the storage area.Frequently observe the operation state of the heart compressor of the cold storage equipment and its exhaust temperature. During the season change operation, pay special attention to the operation state of the system and adjust the liquid supply and condensation temperature of the system in time. - Installation of the vertical plate of the cold storage: select the angle first according to the site conditions and locate it (i.e. lock the vertical plate and the floor) to extend to both sides at this angle. Only lock the vertical plate and the vertical plate, and locate it when it meets the vertical angle. Put the beautiful plate in a conspicuous place. When installing it on the side of the evaporator, make the drainage pipe in advance, and make U-bend and silica gel outside the storage.

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.Honesty and mutual benefit,Watertight polyurethane rigid foam has low water absorption, good permeability to water vapor, 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.Evaporator is not only an exchanger for refrigeration and bulk cooling, but also a very important one. Its task is bulk cooling. It is mainly used for refrigeration and heat absorption in fresh-keeping warehouse. In the long-term work of the fresh-keeping warehouse, the fins of the evaporator will also be covered with dirt, mostly pasted with some sundries of the products. It is specialized in products and renewable resources. Its business includes: cold storage installation, cold storage installation, cold storage construction, fruit fresh-keeping cold storage, medical cold storage. In addition, dust and other things, but reaching a certain thickness will have an impact on the cooling of the fresh-keeping warehouse, If the refrigeration of the fresh-keeping warehouse becomes poor, it should be cleaned with a special cleaning agent for the evaporator.The structure of contemporary cold storage is in the development trend of prefabricated building cold storage. It is made into prefabricated components of cold storage including steam barrier and heat insulation plate to ensure on-site assembly. Its advantage is that the project construction is convenient, rapid and movable, but the project cost is relatively high.portland ,The machine room of ammonia refrigeration system shall be equipped with exhaust assembly; The exhaust fan shall adopt anti motor. When the power supply is cut off due to unexpected refrigeration, it shall be able to ensure the reliable power supply of the exhaust fan. The overload protection of the exhaust fan should be applied to the signal alarm system without directly stopping the exhaust fan. The button box of the exhaust fan shall be concealed in the wall outside the ammonia compressor room.Cold storage has good water tightness. Polyurethane rigid foam has low water absorption, good permeability to water vapor foam holes, disconnected and closed porosity of more than %. It is a dense microporous foam material,portland Cold storage maintenance and installation, which is more dense than air surface, and is not easy to permeate. It belongs to hydrophobic materials.A large number of personnel are not allowed to select goods in the warehouse. Close the warehouse door in time. When the warehouse door is opened, pay attention to whether the air curtain is opened or the door curtain is placed properly. Turn off the lights when leaving the warehouse.
