Whether the water pump works normally and whether the moldy switch is effective. In case of abnormality, timely handle the overhaul and maintenance of the refrigeration compressor in the cold storage: generally, the refrigeration oil and drying filter shall be replaced times after the operation of the cold storage equipment. Replacement after half a year. Depending on the circumstances.Floor insulation of small cold storage the structure of small cold storage is usually called surface, that is the top, wall and ground are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, because the loading and unloading of small cold storage is often handled manually rather than forklift. Of course, if the height of the warehouse is high and the forklift is required for warehousing, loading and unloading, but the ground needs to be insulated separately like the ground insulation sample of medium-sized cold storage.Svietrahorsk,The maintenance of electrical equipment in the wholesale of fresh-keeping warehouse equipment is actually operated by welders or staff who understand the knowledge of power consumption. The switching power supply must be disconnected during maintenance.During the use of cold storage, attention shall be paid to the collision and scratch of the storage body to avoid the depression and corrosion of the storage plate, which will seriously reduce the local thermal insulation performance of the storage body.Volgograd,Quick freezing storehouse is widely used. There are many kinds of temperature in quick freezing storehouse, and multi temperature or double temperature can be realized to meet the needs of different customers. Fault phenomena: unit current is large and voltage is too low; Loose wiring; The unit pressure exceeds the rated pressure; The oil separation core is blocked; Device failure; Host failure; Main motor fault; Fault phenomenon: the unit cannot be started and the fuse is broken; The temperature switch is broken; Loose wiring; Thermal relay of main motor acts; The thermal relay of cold storage fan motor acts; The transformer is broken; No power input (unit); Failure not eliminated (unit); The actuator is faulty.Whether the water pump works normally and whether the moldy switch is effective. In case of abnormality, timely handle the overhaul and maintenance of the refrigeration compressor in the cold storage: generally, the refrigeration oil and drying filter shall be replaced times after the operation of the cold storage equipment. Replacement after half a year. Depending on the circumstances.The selection of cold storage is very important for cold storage, because cold storage is different from ordinary cold storage. The temperature in cold storage is usually low, and the air temperature, humidity and environmental requirements are relatively high. When selecting cold storage, attention must be paid to the selection of cold storage with better temperature. If the selection of cold storage is not good, the temperature in the cold storage is difficult to which is easy to cause the deterioration of products in the cold storage, or the refrigeration compressor in the cold storage often works, cold storage board, as an important structure of cold storage, is also increasing. Because cold storage is different from other ordinary cold storage, it is important to the installation environment and temperature. Therefore,SvietrahorskDesign and installation of quick freezing cold storage, some small problems may be ignored during installation. According to the following understanding.Do not cut off the main power supply to shut down the unit unless it is an emergency; If the unit is out of service for a long time in winter, turn off the unit first, then turn off the main power supply and oil heater, and drain the water in the system. - precautions for floor installation of cold storage: the floor shall be installed flat, the uneven part shall be leveled with materials, and the locking hook between the plates shall be locked to ensure that the warehouse surface is flat without hollow feeling. (note that if this drainage system is installed outdoors in the north, the drainage pipe shall be insulated).The cheapestInsufficient refrigeration dose and capacity in the system: there are two main reasons for insufficient refrigerant circulation,The common phenomenon of quick freezing storehouse is that the temperature of quick freezing storehouse can't drop down or drops slowly. Now, a simple analysis is made on the reasons for the slow drop of temperature: the cold capacity loss of quick freezing storehouse is large due to poor thermal insulation or sealing performance; the poor thermal insulation performance is due to insufficient thickness of thermal insulation layer of pipeline and warehouse thermal insulation wall, resulting in poor thermal insulation and thermal insulation effect, It is mainly caused by improper selection of insulation layer thickness in design or poor quality of insulation materials in construction.Pay attention to the energy saving of the lighting system: the lighting of the cold storage should be considered comprehensively according to the area, science and rationality, from the perspective of energy saving and environmental protection. The lighting in the cold storage is concentrated in the working area.

Requirements for the cold storage time of the device: the cold storage of the refrigeration system using ammonia as refrigerant shall be supported in the place with low population density around.Process inspection,SvietrahorskMedical cold storage installation,Cold storage design segmentation: several different partitions shall be reasonably planned and divided according to purpose and temperature. For example: processing room,SvietrahorskInstallation cost of small cold storage, sorting room, refrigeration room, channel, unloading platform, etc.The valve temperature sensing package shall be fastened at the evaporator outlet with a metal clamp for mm & mdash; mm, tightly wrapped with double-layer insulation.When outdoor air enters the cold storage body, it will not only increase the cold consumption of the cold storage, but also bring water into the warehouse. The condensation of water will lead to the building structure, especially the heat insulation structure, being damaged by moisture and freezing. Therefore, a moisture-proof and heat insulation layer should be set to keep the cold storage board building moisture-proof and air-proof performance and good sealing.Svietrahorsk,These are several very common cold storage materials. The use of these materials has greatly improved the thermal insulation and refrigeration performance of the cold storage which makes people's retained items more convenient and reliable. With the continuous development of material technology, today's various cold storage materials emerge in endlessly, and the cold storage is different from each other. When purchasing, we should make reasonable comparison and select products suitable for our own use needs and economic conditions.General quick-frozen warehouses are mostly cooled by refrigeration mechanism with low gasification temperature (ammonia or Freon)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.
