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.Regular oil discharge, descaling and air discharge: when there is a .mm thick oil film in the evaporator coil, in order to maintain the set temperature requirements, the evaporation temperature will decrease by ℃ and the power consumption will increase by more than ; When the scale on the water pipe wall in the condenser reaches mm, the condensation temperature will rise by ℃ compared with the original temperature, and the power consumption will increase. When the refrigeration system is mixed with non condensable gas and its partial pressure reaches .mpa, the power consumption will increase by about . It can be seen that it is coldGra,Advantages: no reciprocating motion,GraCold storage and freezing of drugs, so it has the advantages of simple structure, small volume, light weight, few parts (especially few vulnerable parts) and high reliability; Torque change is small. I am engaged in all kinds of cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage and other materials all year round. I operate in good faith. Welcome to call! High balance, low vibration, stable operation and low vibration of the whole machine; It has high efficiency and variable frequency speed regulation technology in the range of refrigeration capacity; The scroll refrigeration unit has no clearance volume, can maintain high volumetric efficiency, low operation noise, good stability and high safety, and is relatively not easy to liquid hammer.Step of cold storage design: define the volume of the cold storage warehouse. The size of the cold storage should be based on the design of a large number of agricultural products to be stored for a long time. This volume is calculated based on the essential volume of stored goods accumulated in the cold storage plus the row to row corridors, the indoor space between the pile and the wall, the ceiling and the gap of the packaging house. After the volume of the cold storage is determined, the length and height width ratio of the cold storage shall be determined. Necessary auxiliary engineering buildings and equipment shall also be considered in the design of cold storage such as working intermediate, special tool warehouse, loading and unloading platform, etc.Ndibene Dahra,Improper adjustment or blockage of throttle valve, too large or too small refrigerant flow: improper adjustment or blockage of throttle valve will directly affect the refrigerant flow into evaporator. When the throttle valve is opened too large, the refrigerant flow is too large, the evaporation pressure and evaporation temperature also increase, and the decline rate of warehouse temperature will slow down; At the same time, when the throttle valve is opened too small or blocked, the refrigerant flow will also decrease, the refrigeration capacity of the system will also decrease and the decline rate of warehouse temperature will also slow down.Installation of box and operating device: the design of box shall be reasonable, and the appearance quality shall meet the requirements of beauty and practicality. All buttons, electrical switches,GraWhere is it cold, etc. shall be reliable, safe, long-term cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, old brand, price advantage and quality guarantee! Easy to identify and operate. The indicator light shall be simple and clear. The device and each switch shall be installed on the upper side outside the warehouse door, which is easy to operate, read data and not easy to be damaged, and shall be reliably fixed. 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, and the height of the bottom edge of the switch box is about mm.We must often use insulation board in our life. It's just the structure of the refrigerator, but the refrigerator as a in the home, still has some use environment. In the market or marine transportation, the environment of cold storage insulation board is not so optimistic. Professional cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage quality assurance. During the preferential activities, new and old customers are welcome to consult. The environmental differences inside and outside the cold storage insulation board are very large, because a large number of items need to be insulated, so the temperature in the cold storage is strict. In such cases, the cold storage insulation board will have relevant problems, Let's understand that the water vapor pressure outside the plate warehouse of the lower cold storage is higher than that inside the warehouse, and the penetration of the envelope is carried out from outside to inside all year round. R gas in polyurethane is replaced by air and water vapor to damp polyurethane. Over time, moisture becomes more and more serious, and even water vapor condensation occurs, resulting in low thermal conductivity and reduced thermal resistance. In order to avoid and delay polyurethane moisture and prolong the service life of the insulation layer it is effective to seal the hot side of the insulation layer, that is, and pay attention to the waterproof of the lamp.The cooler on the refrigeration unit is very easy to be dirty, so it should be cleaned on time according to the specific situation. To maintain stable heat conduction and practical effect. Good heat removal and cooling. There is no need to accumulate dirt around the refrigeration unit.Cold storage has good water tightness. Polyurethane rigid foam has low water absorption,GraDesign of small cold storage, good permeability to water vapor, foam holes, disconnected and closed porosity of more than %. It is a dense microporous foam material, which is more dense than air surface, and is not easy to permeate. It belongs to hydrophobic materials.retailer,There should be excellent drainage pipe standard around the warehouse, the soil temperature should be low, there should be interlayer under the cold storage, and maintain good natural ventilation. Maintaining dryness is very important for the cold storage. In addition, the phase electricity of the relative volume shall be built according to the output power of the refrigeration unit. If the cold storage is water-cooled and radiating, the deterioration of foam performance is also a very important index. When the white material is prepared, but it will become brittle after use for a long time in the cold storage, and will no longer resist impact and collision. In addition, the poor hydrolysis resistance of some polyester foam will also affect the service life of the foam. It adopts polyether structure, which is slightly brittle at the initial stage, but generally disappears after a few days, and then maintains the stable performance of cold storage insulation materials for a long time.During production in the production workshop, the unit weight of Pu warehouse board shall not be less than the unit weight required by the project,It is required to set up a special tally room (area), and the temperature of the tally area is usually controlled at ~ + ℃.The fresh-keeping storehouse is a device that combines a refrigerator with facilities that use cooling capacity. The design and construction of refrigeration devices is to effectively use cold energy to refrigerate food or other items; This time, the specific reasons for abnormal exhaust temperature in the fresh-keeping warehouse are introduced.Polyurethane foam: This is also a very common cold storage material. It has strong thermal insulation effect and strong mechanical strength. Now it is widely used and has a good application prospect.Gra,Vent valve or water seal well shall be set at the outlet of flushing (thawing) drainage pipeline. Cold proof measures shall be taken for exhaust valves and water sealed wells in severe cold areas.Polyurethane spraying is widely used in large and medium-sized refrigerators. Different well-known brands are produced at different prices, and the product quality is relatively large. However, it is not high-quality or good goods. This is the result of long-term cooperation. - precautions for vertical plate of cold storage: vertical plate display
