The casing of the protector for the coupling of the coupler is an alloy die casting。 The shell thickness of 4mm, surface spray, color matte, yellow。 The casing of the protection box has a good waterproof, wind proof and sand proof seal structure, and the protection grade of the box can reach IP65。 All electrical joints are in the protection box, and no additional bridge fittings are needed, and the connection is safe, stable and reliable。 There is a positive protective box with a lock, and only to open the door, the door of the thickness of 5mm。 In order to prevent the change and human destruction, the safety of the operator is guaranteed。
The packing of the coupler must ensure that the product is not damaged in the transportation because of poor packing。 The product packaging should be dust-proof, moisture-proof, anti vibration, etc。, which is in line with the requirements for the long-distance transportation of electronic instruments。 The products are outsourced with plastic bags and reloaded into wooden cases。 In the wooden cases, there should be instructions for the use of products, inspection certificate and other documents, the corresponding accessories and accessories。
When loading and unloading, the packing shall be handled with care and light, and stacked in the direction specified by the mark, so as to avoid collision and impact. During transportation, it is forbidden to transport the corrosive articles such as acid and alkali in the same carriage. The packing should be kept in the storeroom of ventilation, drying and moistureproof, and no corrosive goods such as acid and alkali are placed in the same library.
High order inverter output will reduce the efficiency of the motor, increasing heating。 In order to heat the heat, the motor needs to increase or install the cooling fan。 (the heat dissipation of the motor is proportional to the speed of the motor, and the motor is designed to be a constant speed when the hydraulic coupling is used)。 The frequency converter can not provide the characteristics such as the non load starting of the hydraulic coupling and the vibration isolation of the shaft system。 The wave generated by the frequency converter may interfere with the main power supply。 When starting, the pulse may affect the other electronic systems (PLC computer, etc。) connected by the main power supply。 The filter can prevent the frequency converter from generating pulse when starting, but the filter is very expensive and reduces the efficiency of the frequency converter。
