The efficiency of the compressor is low, ring and other parts are seriously worn the long-term cold storage installation, installation, construction, fruit preservation, medical cold storage and other brand products, the designated products are complete, 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.

However, long-term continuous operation will inevitably lead to equipment aging, so reasonable maintenance is particularly important.

San-Miguel.The electric cabinet shall be in strict accordance with the requirements of the drawing,San-MiguelPreservation technology of vegetables in cold storage, and the power shall be connected for no-load test.

The construction of small cold storage is widely used in life, such as food industry, manufacturing industry, etc. since cold storage is so widely used, do you know cold storage? Especially the construction process and steps of cold storage. Understanding the construction process and steps of cold storage is helpful for all links of cold storage maintenance.

.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,San-MiguelWhere is the refrigerator installed, 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.

Cold storage design step: the selection of cold storage refrigeration system the selection of cold storage refrigeration system is mainly the use of cold storage refrigeration compressor and air conditioning evaporator. Generally, small and medium-sized refrigerators are dominated by fully enclosed refrigeration compressors. Due to the small output power of the fully enclosed refrigeration compressor the price is relatively cost-effective; Small and medium-sized refrigerators are generally dominated by semi closed refrigeration compressors; Semi closed refrigeration compressor is adopted for large and medium-sized refrigerated warehouses. When adopting, ammonia refrigeration unit can also be considered. Because the output power of ammonia refrigeration unit is large and can be used for machine use, but the installation and management of refrigerated warehouses are cumbersome. When using the air-conditioning evaporator, the high-temperature cold storage uses the industrial cold fan as the air-conditioning evaporator. Its characteristic is that the temperature reduction speed is faster but it is easy to lead to the water consumption of the cold collection; Medium and ultra-low temperature refrigerators are dominated by seamless evaporation pipe slots, which is characterized by very good temperature control effect and moderate cold storage.

The structure of contemporary cold storage is in the development trend of prefabricated building cold storage. It is made into prefabricated components of cold storage including steam barrier and heat insulation plate to ensure on-site assembly. Its advantage is that the project construction is convenient, rapid and movable, but the project cost is relatively high.

Panel types of quick freezing warehouse: color plastic steel plate, salted steel plate, stainless steel plate, embossed aluminum, etc.

There are several types of insulation materials. One is to produce and process plates with fixed shape and specification, fixed length, total width and thickness. Plates of corresponding specifications and models can be selected according to the installation of the refrigerator body. High and medium temperature refrigerators generally use 10cm thick refrigerator plates, and ultra-low temperature refrigerators and freeze-cleaning refrigerators generally use 12cm or 15cm thick refrigerator plates; Another kind of sprayed polyurethane foam can be sprayed immediately into the finished brick or concrete warehouse. After forming, polystyrene grease, etc. polyurethane is non hygroscopic and has good fire resistance, but the cost is high; Polystyrene resin has strong water absorption and poor fire resistance, but the cost is low. The structure of modern cold storage is developing in the direction of dress matching architecture. They are made into prefabricated components including steam barriers and heat shields to ensure field assembly. Its advantage is that the project construction is convenient, fast and movable, but the project cost is relatively high.

When the cold storage is built, the diffusion of water vapor and the infiltration of air shall be prevented. When outdoor air invades, it will not only increase the cold consumption of the cold storage, but also bring moisture into the warehouse. Moisture condensation will damp the heat insulation structure and freeze and damage the cold storage structure. Therefore it is necessary to set moisture-proof and heat insulation layer, professional cold storage installation, installation of cold storage, cold storage construction, fruit fresh-keeping cold storage, medical cold storage and other products, which have a complete variety, sell well at home and abroad, and have a long service life! Products lead the wire industry. Welcome to inquire, so that the cold storage building has good sealing, moisture-proof and steam isolation performance.

total cost.For water-cooled units, the turbidity of cooling water shall be frequently, the cooling water shall be replaced frequently, and whether the running,San-MiguelInstall cold storage, emitting, dripping, leakage and other conditions of the water supply system exist.

The cold storage shall be regularly overhauled and maintained, so as to reduce the failure rate of the refrigeration unit and achieve good refrigeration effect.

Wall and floor fixtures shall start at corners. According to the plate layout drawing 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, tighten the angle iron, 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, which usually includes two parts: the cold consumption during cargo cooling and refrigeration; It is the cooling consumption of the refrigeration room itself and operation management.

San-Miguel.Application of parallel compressor in cold storage: the requirement of refrigeration capacity is large, and 5 to 50 refrigeration compressors under 20 Malige need to be used on weekdays; Long term operation, large load peak valley difference and significant departmental load; Frozen and refrigerated objects are novel foods that are easy to decay and degenerate, and have strict requirements for temperature and humidity.

The spacing of pull rivets at inner and outer corners is 300mm and 200mm respectively; After the polystyrene library is installed, the wall panel joints shall be evenly sealed and decorated with silicone sealant.

The temperature and humidity in the warehouse shall be kept uniform without movement; Try to finish the food in the warehouse at one time.
