The butt joint between the top warehouse plate and the end of the top warehouse plate shall be treated to prevent air leakage and cold running. After all the top warehouse plates are installed， the butt joint shall be filled with foaming material， and the mm wide color steel plate shall be sealed at the butt joint with pull riveting.
La Asuncion However， long-term continuous operation will inevitably lead to equipment aging， it shall be conducive to production， construction and dry ceremony.
However long-term continuous operation will inevitably lead to equipment aging， so reasonable maintenance is particularly important.
Polyurethane refrigeration board uses light polyurethane as the internal material of refrigeration board. The advantage of polyurethane is very good heat insulation. The exterior of the cold storage is composed of SII， PVC color steel plate and stainless steel plate. The advantage of this is that it can prevent refrigeration， because the temperature difference inside and outside the board is large， and the temperature will disperse， which makes refrigeration more energy-saving and improves the working efficiency of refrigeration.
However， not all controlled atmosphere reservoirs can choose to adjust with a large depth which still needs to be determined according to the actual needs of fans and places. We can adjust the energy-saving effect of the control fan from the production design link， coupled with the user"s energy-saving effect of the hot air fan， so that no other adhesive materials are needed. When polyurethane is used as a cold storage project， and then solidified and pressed to form a multi shape storeboard， because the metal plate can roll out different waveforms， so that the overall rigidity is stronger and the bearing capacity is higher. Polyurethane filler board can meet the firmness and physical requirements of exterior wall and can be used in various cold storage projects. It is technically feasible and cost-effective. Yuanbao refrigeration believes that polyurethane is one of the new cold storage materials with great development prospects in the future. The thermal insulation materials of cold storage engineering should not only have good thermal insulation performance， but also be economical， applicable and environmental friendly. To ensure the smooth progress of our cold storage project， we should not only inquire about the raw materials of the cold storage， but also the types of cold storage. The common cold storage plates mainly include the following types， namely stainless steel plate， color zinc steel plate salted steel plate， embossed aluminum plate and mm galvanized standard floor plate.
discountThe 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.
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.
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.
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.
Installation materialsOperating 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.
The wholesale electronic control system of fresh-keeping storehouse is the main component of the wholesale intelligent system of fresh-keeping storehouse. The intelligent electronic control has the functions of automatic cooling， stop， defrosting， delay and other related functions. The electronic control humanized mode saves the complicated work of manual operation. The wholesale seafood machine of fresh-keeping storehouse is used for seafood breeding and other temperature systems. The principle is similar to that of air conditioning. The main components are titanium barrel， fan， condenser， compressor，Palma SorianoHow much is a cold storage， temperature controller， through valve and other components. Next， fresh-keeping warehouse wholesale is introduced in detail
The type of cold storage to be built in the type of cold storage should be determined according to the type of circulating goods. For example the cold storage that only circulates vegetables can only build a fresh-keeping cold storage， while the cold storage with refrigeration + freezing will be built if there are many types of circulating goods and great difference in storage temperature. As for the size of the cold storage， it should be determined according to the type， frequency， cycle， whether to use shelf stacking and so on. For example， for fruits and vegetables packed in cartons， the storage capacity of -kg per cubic meter can be referred to， and the size of cold storage construction can be estimated in combination with the storage capacity rate of about .-..
Palma SorianoFault phenomenon: fan motor overload， fan deformation; Fan motor fault; Fan motor thermal relay fault (aging); Loose wiring; Cooler blocked; Large exhaust resistance. Cold storage fault phenomenon: dryer does not operate，Palma SorianoInstallation of cold storage works， compressor line is disconnected， fuse is blown， thermal relay acts， high voltage switch acts， compressor is locked， line is falsely connected or loose fault phenomenon: it stops in a short time after drying， ambient temperature is too high， condenser is blocked
Step of cold storage design: selection and laying of cold storage thermal insulation materials. The use of cold storage thermal insulation materials must be adjusted to the time， which not only has excellent fire resistance， but also has high cost performance. There are several types of cold storage insulation materials. One is the plate produced and processed into a fixed shape and specification，Palma SorianoHow much does it cost to install a small cold storage， with fixed length， total width and thickness. The cold storage plate with relative specification and model can be selected according to the installation of the warehouse body. The high and medium temperature cold storage generally adopts cm thick cold storage plate， cm or cm thick cold storage board is generally used for ultra-low temperature cold storage and freeze-cleaning cold storage; Another kind of cold storage can be sprayed with polyurethane spray paint and polyurethane foam， and the raw materials can be sprayed into the brick or concrete warehouse of the cold storage to be built immediately. After shaping， it is both waterproof and thermal insulation. Thermal insulation materials include polyurethane， polystyrene grease， etc. Polyurethane is non hygroscopic and has good fire resistance， but the cost is high; Polystyrene resin has strong water absorption capacity and weak fire resistance， but the cost is low.
The efficiency of the compressor is low， and the refrigerating capacity can not meet the load requirements of the warehouse: due to the long-term operation of the compressor， the cylinder sleeve， ring and other parts are seriously worn， the long-term cold storage installation， construction， fruit preservation， medical cold storage and other brand products， the designated products are complete， the quality is guaranteed， and the sealing performance will be reduced accordingly with the increase of the matching clearance， The gas transmission coefficient of the compressor will also be reduced， and the refrigeration capacity will be reduced. When the refrigerating capacity is less than the heat load of the warehouse， the temperature of the warehouse will drop slowly.
