The planetary reducer SCF90-10-P2 is a model of the planetary reducer. The planetary reducer is a very precise reducer product. The sales volume of the reducer ranks relatively high, because the planetary reducer SCF90 is used. -10-P2 There are too many fields or industries, such as metallurgical machinery, environmental protection machinery, electronic appliances, road construction machinery, chemical machinery, food machinery, light industry machinery, mining machinery, conveying machinery, construction machinery, building materials machinery, cement Machinery, rubber machinery, water conservancy machinery, petroleum machinery, etc., the number of planetary reducer products used in these industries has accounted for 60% to 70% of the total number of planetary reducers used in various industries across the country.

As the country attaches importance to the machinery manufacturing industry, the acceleration of the localization of major equipment, and the start of construction projects such as urban transformation and venue construction, the market prospects of planetary reducers are promising, and the entire industry will continue to maintain a rapid development trend, especially gear planets. The growth of the reducer will be greatly increased, which is related to the use of gear planetary reducers in most imported equipment. Therefore, Taiwan’s Yongkun brand geared motor manufacturers have been developing and manufacturing more precise planetary reducer products on the existing basis. Now Taiwan’s Yongkun brand geared motors produce large hard-toothed planetary reducers and medium-sized geared motors. , Small power planetary reducer, etc. to meet market demand.

Compared with worm gear reducer, gear reducer, planetary reducer SCF90-10-P2 has significant advantages. Industry leaders engaged in the production or manufacturing of mechanical equipment are very aware of the advantages of planetary reducers: the advantages of using China AC Gear Motors: planetary gear reducers are light in weight, small in size, large in transmission ratio range, high in efficiency, stable in operation, and noise Low adaptability, high transmission accuracy, wide reduction range, etc. The planetary reducer is a precision reducer with a reduction ratio of 0.1 to 0.5 revolutions per minute.

In most cases, planetary gearboxes are used in conjunction with motors. According to the structural characteristics of the motor, the planetary reducer is also divided into, for example, SCF square flange surface installation, because there is also SCE round flange surface installation. The types of planetary reducers supplied by Taiwan Yongkun Company include SCE, SCF, WSCE, WSCF, PLS, PLE, PLF, VR, etc. The models are divided into 60, 80, 90, 120, 140, 180, 190 and customized models.

Inverter is a kind of variable speed drive system software. It uses DC variable frequency drive technology to change the frequency and strength of Brake AC Gear Motors Company working standard voltage to smoothly control the speed and torque of AC motor. The most common one is that the input and output are all AC current. Communication/communication converter. The frequency converter has a wide range of applications, from small and medium-sized household appliances to large and medium-sized mine grinding equipment and refrigeration compressors. About 1/3 of the world's kinetic energy is consumed on motors that drive fixed-speed centrifugal water pumps, cooling fans and refrigeration compressors, and the market penetration rate of frequency converters is still not high. The obvious improvement of the high efficiency of electric energy is one of the key reasons for the application of frequency converters. With the continuous promotion of industrial automation, the application of frequency converters in the industrial production industry has become more and more common, and the maintenance and repair problems also seem to be increasingly critical.

Three elements for high-efficiency operation of frequency converters:
1. Common problems during normal operation
1. Is there any abnormal noise and vibration in the motor?
2. Whether the inverter and motor are hot and abnormal.
3. Is the working temperature too high?
4. Is the load current meter the same as the previous value?
5. Is the cooling fan of the inverter operating normally?
Note: The daily maintenance and repair of the inverter must be carried out in accordance with the product manual.

 2. Usual inspection matters
1. Check the refrigeration system and eliminate the dust in the air filter.
2. Check whether the standard parts on the inverter such as screws and anchor bolts are loose, and carry out the necessary tightening; check whether there are erosion, discoloration, cracks, damage, etc. Welding parts and riveting terminals, and check whether the frame shear wall is loose, whether the transmission lines and cables are damaged, etc.
3. Check whether the connection of the control circuit board is loose, whether the power capacitor is leaking, whether the line on the board is rusted or cracked, etc.
4. Check whether the coupling capacitor is leaking and whether the capacitor is reduced.
5. Check whether the grounding resistance is within the standard value range.
Note: It is suggested that regular maintenance should be carried out once a year.

3. Replacement of accessories
To make the frequency converter operate reliably for a long time, it is necessary to carry out maintenance on time for the service life of the electronic components in the frequency converter, and to dismantle and replace the key components of the frequency converter according to the service life.
1. The switching power supply of the cooling and cooling fan inverter is the most serious heating device. The heat generated during continuous operation must be discharged immediately. The damage of the centrifugal fan is not easy to warn and cannot be estimated. Therefore, the time must be removed and replaced. Because it's small and big. The service life of the general cooling fan is 10kh-40kh. According to the continuous operation of the inverter, the cooling fan should be removed and replaced once every 2 to 3 years, and the cooling fan for immediate cooling has the difference between the second and the third line. The first line of the second line cooling fan is the positive stage and the other line is the negative stage. In addition to the positive and negative stages of the three-wire cooling fan, there are also inspection stations. When disassembling and replacing, always pay attention to communication. The AC centrifugal fan is generally 220v, 380v point is 220v, and 380v point. The working voltage level of disassembly and replacement should not often fail. Reliable universality The well-known brand inverter power supply will have a professional maintenance chapter catalog in the hardware configuration guide, and the key initial use period, replacement cycle time, etc. will be marked internally. If there is no such content, it means that the inverter you purchased is not a well-known brand, and it is suggested to replace it.
2. Electrolytic capacitor The key passive components in the inverter, which are composed of inductors, capacitors, resistors, etc., are called filters. Its function is to get a special frequency or clear a special frequency. The volume size of the coupling capacitor is positively related to the amount of current in operation. In other words, the larger the amount of current in operation, the larger the volume of the necessary capacitor. The service life of power capacitors is generally 5 years. The volume of the capacitor should be regularly maintained once a year. Generally, it should be replaced when the volume is reduced by more than 20%.
