which are different. For a long time

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.There are many application scenarios of cold storage, it provides various cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, on-site settlement, honest operation, and has offices all over the country for long-term cooperation. Different purposes, functions and designs, so what needs to be understood in cold storage design?DILBECK,DILBECKCold storage installation,Before the installation of the controlled atmosphere warehouse,DILBECKRefrigerated vegetables in cold storage, we should also know how long the time demand for freezing goods is. After the installation of the controlled atmosphere warehouse, it can be divided into fresh-keeping warehouse, cold storage, frozen storage and quick-frozen storage. The first thing for the fresh-keeping warehouse is to store regular items, and the first thing for the frozen storage is items around zero, The freezing time code takes hours. If it is put into the quick freezing warehouse, it only takes to hours to reach the phenomenon of quick freezing. In the process of depositing goods, if the temperature is too low, it will affect the normal temperature of the deposited goods. The high price cold warehouses of various specifications are installed, installed, constructed, fruit fresh-keeping cold warehouses, and medical cold warehouses are supplied in time, High cost performance, has become the preferred brand for many wire products, welcome to buy! It will also affect the shelf life.Another reason is that there are many refrigerants in the system. In this case, find the leakage point first, focus on the connection of each pipeline and valve, repair the found part, and then fill in sufficient refrigerant.Sao Tome and Principe,The spacing of pull rivets at inner and outer corners is mm and mm respectively; After the polystyrene library is installed, the wall panel joints shall be evenly sealed and decorated with silicone sealant.The refrigeration equipment in the fresh-keeping environment of the quick-frozen warehouse mostly adopts the single-stage compression refrigeration system, with freon as the refrigerant. The evaporation mode in the warehouse is the cooling fan,DILBECKCold storage engineering design and installation manufacturer, which can be ceiling type. If the number of warehouses is small and the volume does not exceed cubic meters, the refrigeration mode of the warehouse machine can be considered. If there are a large number of warehouses, the mode of multiple heads in parallel can be considered.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.

The selection of equipment for the construction of equipment cold storage is closely related to the size, in the daily use of fresh-keeping warehouse wholesale we should avoid scratching or collision caused by objects on the warehouse board. The purpose of this is to avoid dents and scratches after the wholesale warehouse board of fresh-keeping warehouse is impacted. In serious cases, it may also affect the refrigeration effect of fresh-keeping warehouse wholesale, resulting in the reduction of local temperature control effect of cold storage.The polyurethane insulation board used in the construction of cold storage shall be integral and continuous, and there shall be no joint in the middle. The junction of polyurethane insulation board, top plate and ground shall be made into fillet arc for transition, which can well meet the health needs.Bidding, and the door of the cold storage must be locked.Operating the unit: regularly observe the oil level and oil return of the compressor and the cleanliness of the oil. If the oil is dirty or the oil level drops, it shall be solved in time to avoid adverse effects.Whether there is dirt on the condenser and poor heat dissipation will lead to too high condensation pressure of the refrigerator. In order to protect the compressor, the machine stops running under the action of the pressure controller. When the heat dissipation is good, press the black reset button on the pressure controller, and the machine can automatically resume operation.

There are two kinds of refrigeration in the cold storage group: immediate refrigeration and simple refrigeration.Encyclopedic knowledge,Judge the operating sound of the compressor, and carefully listen to the operating sound of water pump, cooling tower, compressor, fan and other equipment. In case of abnormal sound, timely warranty is required, another important finishing work is to purge the whole system. Compressed air will clean out the impurities remaining in the controlled atmosphere storage, which plays a key role in the use of the controlled atmosphere storage.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.DILBECK, the production shall be carried out in strict accordance with the operation rules specified in ISO quality operation which is the lowest among all thermal insulation materials at present.Technical assurance measures for the installation of cold storage: during production in the production workshop the thermal conductivity is only . ~ .w / (m.k), self inspection and inspection application shall be carried out to ensure that the factory pass rate is, and unqualified products are not allowed to leave the factory.Polyurethane foam foam dimensional stability: cold storage polyurethane foam in severe temperature changes or at a relatively low temperature will appear dimensional changes (as contraction), 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.
