San Rosa de CopanFresh fruit cold storageTackling key problems and improving yield

The evaporator surface is too thick or too much dust, and the heat transfer effect decreases: another important reason is that the heat transfer efficiency of evaporator is low, which is mainly caused by excessive frost or excessive dust on the evaporator surface.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.San Rosa de Copan,Ammonia filling leak test: ammonia filling leak detection can be carried out after system blowdown and pressure leak test. The purpose is to improve the air tightness of the fresh-keeping warehouse system and lay a good foundation for the system to fill ammonia and wrap thermal insulation materials.The average service life of rigid polyurethane insulation structure with stable quality, long service life and high comprehensive cost performance can reach more than years under normal use and maintenance conditions. Under the normal service conditions during the service life of the structure, it will not be affected by drying, or electrochemical corrosion, as well as the growth of insects, fungi or algae or rodents.Polokvani,Cold storage design segmentation: several different partitions shall be reasonably planned and divided according to purpose and temperature. For example: processing room, sorting room, quick freezing room, refrigeration room, channel unloading platform, etc.Wall and floor fixtures shall start at corners. According to the plate layout drawing,San Rosa de CopanHow to charge for the installation of cold storage, transport the two plates at the corner of the required device to the device location. According to the plate beam height and the model of the angle iron for fixing the mushroom head nylon bolt, drill a hole at the corresponding elevation in the middle of the plate width. When drilling, the electric drill should be perpendicular to the plate surface. Put the mushroom head nylon bolt in the hole, and tighten it horizontally, so as to make the nylon bolt on the surface of the warehouse plate slightly concave. When setting up the wall panels, foam data and other soft data should be laid on the floor slots along with the floor of the storehouse, so as to avoid damaging the storehouse. After the two corner panels are neutrally removed from the floor, the plane position of the wallboard and the verticality of the storehouse should be adjusted in time according to the location of the laying line, and check whether the top elevation of the wallboard can be correct. After the position of the wallboard is correct, weld the angle iron on the plate beam and fix the inner and outer corners. When welding the angle iron parts, the angle iron parts of the warehouse plate shall be covered with a shield to avoid the high temperature of the welding ground baking the warehouse plate and welding slag on the warehouse plate during electric arc welding.There are two kinds of refrigeration in the cold storage group: immediate refrigeration and simple refrigeration.

First, use a hammer to pad the wood on the polyurethane warehouse board between the two warehouse boards, so as to make the boards closely close to each other. Two sets of connecting pieces shall be wedged between the wall panel and the wall panel, and the two sets of connecting pieces shall be fixed on the upper, outer and lower sides of the gap between the wall panel and the wall panel respectively. The lower connecting piece shall be as close as possible to the lower side, so that the post cast concrete can cover the connecting piece. After the gap between the plate and the plate ground is wedged with a connector, it shall be about mm wide. If it does not meet the requirements, remove the plate, trim the plate edge, and then reinstall it to make the plate joint meet the requirements. When fixing the adapter, pay attention to fix the two parts of the adapter on the edges of the convex and concave library plates respectively,San Rosa de CopanWhat cold storage installation companies are there, and fix them with rivets. The spacing of the adapter should be able to tension the two library plates. When wedging the wedge iron, the hammer shall be perpendicular to the wedge iron to prevent damaging the warehouse plate. The ground wedge iron at the upper and lower parts shall be wedged at the same time, and the wedge iron shall be fixed with rivets.Vibration shall be prevented during the whole operation of the refrigeration unit. In addition to the abrasion of the lifting mechanical equipment, vibration will continue to cause loosening or cracking of the upper connecting pipe of the generator unit. If abnormal noise is found during the whole operation of the equipment, it shall be shut down for inspection before operation. The maintenance functions of the refrigeration unit have been set and do not need to be adjusted.The insulation board of the cold storage adopts polyurethane double-sided color steel plate. The main effect of this cold storage insulation board is good sealing performance, insulation effect and moisture-proof effect, so as to ensure the refrigeration effect of the cold storage. The electric cold storage door is adopted for the cold storage door, and the cold storage management personnel can timely and effectively open and close the door when entering and leaving, so as to avoid the loss of refrigeration capacity of the cold storage.Promotion,The combined cold storage door starts frequently or does not start for a long time, or does not stop for a long time, or stops before the storage temperature reaches.The exhaust temperature of the compressor equipment is often. When the season changes and the temperature difference changes greatly,San Rosa de CopanQuotation for installation of small cold storage, pay attention to it. If the machine is abnormal, it needs to be checked in time.When outdoor air enters the cold storage body, it will not only increase the cold consumption of the cold storage, 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.

The lights in the warehouse are not on. Please check whether the switch fails and whether the bulb is damaged. Cut off the power supply when installing the lampshade, and pay attention to the waterproof of the lamp.analysis,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, and are equipped with combined thermal insulation storage body, unloading platform refrigeration system, pipeline system system etc. according to the actual needs of cold storage circulation.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.Core tip: in the cold storage project, only with sufficient cold storage installation skills can we ensure that the cold storage is more energy-saving and power-saving after installation, and is not prone to failure,The door of the combined cold storage is not tightly closed. Please adjust the distance between the hinge on the door and the door lock and the storage body.As a coolant, make it evaporate under low pressure and mechanical conditions to absorb the heat in the storage, so as to achieve the purpose of cooling.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, packaging and combing room, special tool warehouse, loading and unloading platform
