The hydraulic cylinder of an excavator is one of the important hydraulic components responsible for driving and controlling mechanical movements. In order to ensure the normal use of hydraulic cylinders and extend their service life, daily maintenance is necessary.
1. Regularly clean the hydraulic cylinder: During use, the hydraulic cylinder will be attacked by various pollutants, such as dust, sediment, oil stains, etc. These pollutants can affect the working efficiency and lifespan of the hydraulic cylinder. Therefore, it is necessary to regularly clean the hydraulic cylinder.
2. Regular inspection of seals: The seals of hydraulic cylinders are key components to ensure their normal operation. If the seals are damaged or worn, it can lead to oil leakage or unstable operation of the hydraulic cylinder. Therefore, it is necessary to regularly inspect the sealing components of the hydraulic cylinder and replace them in a timely manner if there is any damage or wear.
3. Regular inspection of hydraulic oil: The operation of hydraulic cylinders requires the support of hydraulic oil, so the quality of hydraulic oil has an important impact on the working effect of hydraulic cylinders. Regularly check the quality of hydraulic oil, and replace it promptly if there is contamination or deterioration.
4. Regularly check the hydraulic pipeline: The hydraulic pipeline is the blood vessel of the hydraulic cylinder. If there is oil leakage or damage to the pipeline, it can cause the hydraulic cylinder to not work properly. Therefore, it is necessary to regularly inspect the hydraulic pipelines and promptly repair or replace them if there is any oil leakage or damage.
5. Regularly lubricate the hydraulic cylinder: The piston rod and piston ring of the hydraulic cylinder need to be lubricated to reduce wear and friction. Therefore, it is necessary to regularly apply lubricating oil to ensure the normal operation of the hydraulic cylinder.
In short, the daily maintenance of excavator hydraulic cylinders is very important, which can extend their service life and improve work efficiency. Regular cleaning of hydraulic cylinders, inspection of seals, hydraulic oil, hydraulic pipelines, and lubrication of hydraulic cylinders are required.
Panasonic upgrades from lighting to audio to seek LED market opportunities
Due to the price war between the lighting factory and the Japanese factory, the Japanese lighting industry decided to turn to the high value-added LED lighting market development, and set out that the new lighting products in 2016 are all LED or OLED products. In 2020, all Japanese home lighting and more than 50% of public facilities. Lighting, replacing the goal of LED lighting and OLED lighting. Recently, according to the Japan Radio News report, Panasonic's LED lighting equipment, Japan's largest lighting factory, is scheduled to launch a new embedded LED lighting product with integrated sound system, emphasizing that lighting is not only the enjoyment of light, but also the feast of the sound, and become An important part of the new generation of smart home appliances controlled by wireless networks, with the building materials business of the plant, expand the possibility of home design. Japan's 2011 Fukushima nuclear disaster promoted large-scale power-saving campaigns, and the LED lighting market with long-term power saving and long service life grew rapidly. In 2013, the sales amount exceeded 50% of the total amount of Japanese lighting equipment in that year, and it officially became a mainstream lighting product. Due to the price war between the lighting factory and the Japanese factory, the Japanese lighting industry decided to turn to the high value-added LED lighting market development, and set out that the new lighting products in 2016 are all LED or OLED products. In 2020, all Japanese home lighting and more than 50% of public facilities. Lighting, replacing the goal of LED lighting and OLED lighting. With most of the lighting equipment on the Japanese market replaced with LED lighting by 2016, the domestic domestic lighting market has no need for old lighting for the LED lighting market since 2017; and the LED lamp has a service life 10 times that of tungsten or fluorescent lamps. Above, the extended fault change interval also delayed the emergence of new LED replacement LED lighting market. With the end of the tide of LED lighting in Japan, the Japanese lighting factory is not optimistic about the future domestic lighting market in Japan, and is beginning to seek new selling points such as customized service and design, and expects to continue the market level. And Panasonic's upcoming new LED lighting horn is a relatively low-end LED lighting product, which is embedded in the wall or ceiling. It can be plugged into the existing diameter and depth of the same type of lighting within 10 cm of the cavity. It is the result of cooperation between the lighting and home appliance business and the building materials business. It is a certain degree of attraction for consumers who do not want to use high budget to change lamps. As Panasonic's official website only refers to the recent disclosure of relevant product details, its brightness and other information is still uncertain. It is only scheduled to be released at the end of February 2018. It can be controlled by wireless network, not only with smartphone remote control and dimming, but also Connected to the TV, as a stereo speaker application outside the main speakers. Moreover, this kind of embedded lighting system usually has more than one installed in each room, so it is equal to a multi-speaker speaker system. Even if a single speaker has a limited volume, the multi-speaker combination can produce a richer sound effect, not only useful for watching TV, but also for mobile phones. The game can also be used to create unexpected effects. Even if this is a product of Panasonic's new residential appliance planning and living space brand, this system is also suitable for use in the exhibition hall of a store or art gallery. The future market development space can be expected. Nowadays, there are still LED lighting markets in Japan that can only be used for lighting and automotive lighting such as Panasonic, Koizumi's art lamps, Kyocera's plant factories and agricultural lighting, etc. Before, how should the Japanese lighting market operate, pending the efforts of manufacturers.
