Hitachi compressor 503DH-80C2Y specifications are divided by the input power. General difference between each specification about 50W. In addition, there are also divided by the cylinder volume key performance indicators Hitachi compressor 503DH-80C2Y input, output power, coefficient of performance, cooling capacity, starting current, running current, rated voltage, frequency, cylinder volume, noise and so on. A compressor performance measure, mainly from the weight, efficiency and noise compared three aspects. According to Chinese standards, its safety performance test is based on the project requirements GB4706.17-2004's. The main project is the electrical strength, leakage current, locked rotor and overload operation test. On the air conditioner compressor performance test, according to GB5773-2004 the regulations. In addition, the product type and production of products that may affect the performance of major changes, continuous production for one year or more than a year later reproduction, as well as factory test results with large differences between the type test, must be type tested . Packaging and storage Hitachi compressor 503DH-80C2Y packaging and transport according to the contract provisions. Large quantities of imported compressor, is generally then loaded into the carton container shipment. Compressor should be fixed firmly in the box, and moisture shock measures. Storage and transportation allowed upside down, and stored in a well-ventilated warehouse, the relative humidity must not exceed 80%, there can be corrosive gases exist. Precautions Hitachi compressor 503DH-80C2Y only when in use, unplug the sealing rubber plugs are allowed. As found in the storage shed or loose plugs, check processing, then the line should be saved. Refrigerator compressor and air conditioner compressor are CCC certification must be carried out only after the sale. Major importing countries Hitachi compressor 503DH-80C2Y compressor supply shortage in the domestic situation, China needs an annual amount of imports. Major trading nations are Germany, the United States, Italy, Japan, Denmark, Brazil, South Korea and so on. In recent years, the domestic compressor manufacturers through the introduction of technology and equipment modification, domestic compressor quality, yield is greatly improved.
