Guangxi Power Grid Corporation issued a Class I red warning of severe power shortage, with a power shortage rate of about 30%, and more than 1,000 companies stopped production. Guangxi suffered the most serious “electricity shortage†in 20 years. “Guangxi suffered a serious power shortage this year. This round of power shortage is faster and more fierce than we expected. The current power gap is close to 30%. Guangxi Power Grid has issued a particularly serious shortage. Electric I-level red warning signal.†Gu Nanfeng, deputy chief engineer of Guangxi Power Grid Corporation, said, “The number of enterprises that have stopped production or partially stopped production in Guangxi has been affected by the lack of electricity.†“Guangxi is suffering from the worst power shortage in the past 20 years. And the longest time-consuming power shortage situation.†Gu Nanfeng told reporters that the current power purchase capacity in Guangxi is 9 million kilowatts, including 2.5 million kilowatts of hydropower, 5.5 million kilowatts of thermal power, and 1 million kilowatts of electricity outside the purchase area. Guangxi's electricity demand is about 13 million kilowatts, the power gap is nearly 4 million kilowatts, and the power shortage rate is about 30%. Guangxi is rushing to introduce coal sources from various places, applying for “borrowing electricity†to Guangdong, Yunnan and other places, restricting high-energy-consuming enterprises and non-general industrial electricity, shutting down lighting projects, and calling on the whole society to save electricity. In the short-term, the lack of water and coal shortages and the surge in demand will increase, and the installed capacity will be insufficient in the long run. “Overall, this power shortage is caused by the power generation capacity in the dry season and the superposition effect of the high-temperature electricity load in summer.†Gu Nanfeng analysis led to There are three main reasons for this shortage of power in Guangxi. First, the hydropower output in Guangxi has fallen sharply. "This year, the Hongshui River suffered the largest drought since the hydrological record, and the incoming water is only 30% of the normal year." Gu Nanfeng said. At present, Guangxi's hydropower output averages 2.5 million kilowatts, which is equivalent to the power generation level in the dry season, which is 2.5 million kilowatts lower than the 5 million kilowatts in the same period last year. Second, the thermal shutdown of coal-fired power plants is serious. Guangxi thermal power plant has a capacity of 1 million kilowatts due to lack of coal, and the operating unit has reduced power generation by 1 million kilowatts due to unstable coal quality. At present, Guangxi's thermal power generation capacity is only 5.5 million kilowatts. Third, power demand has risen sharply. During the “Eleventh Five-Year Plan†period, the industrial added value of Guangxi increased from RMB 126.5 billion in 2005 to RMB 380 billion, and the demand for electricity continued to rise. The demand for electricity in Fangchenggang, Qinzhou and Beihai, the fastest-growing cities in the Beibu Gulf Economic Zone, is about 20%-30%. Since the summer, the continuous high temperature in Guangxi has led to a surge in air conditioning load. "In the long run, due to insufficient installed capacity, the 'hard power shortage' will be difficult to change in the next 3-5 years," said Zhu Chuanyao, director of the marketing department of Guangxi Power Grid Corporation. It is understood that Guangxi needs to add 3 million kilowatts of installed capacity each year to meet the needs of economic and social development. However, this year, Guangxi only added 1.33 million kilowatts of thermal power, and it is concentrated in the fourth quarter. Therefore, it has contributed little to the power supply this year. It is estimated that power generation capacity will be around 2 million kilowatts next year, and it may be less in the next year. Guangxi “guarantee limited†scientific electricity consumption and energy conservation On July 27th, Guangxi held a special work conference on power supply security in the whole district, emphasizing that power supply must protect people's livelihood, protect life and protect key points, especially pay attention to priority to protect urban and rural residents. Basic household electricity and electricity, as well as schools, hospitals, railways, water supply and other important units, electricity for agricultural production and construction of key projects are also included in the priority coverage. “In the next step, we will strengthen the district's power security by optimizing hydropower unit dispatching, encouraging self-supplied generator sets to generate electricity, and increasing support for biomass power generation,†Zhu Chuanyao said. It is understood that in order to effectively pre-control the coal storage in the power plant, Guangxi Power Grid Corporation has also implemented a white, yellow and red warning mechanism for the coal storage in the power plant to fully supervise the power plant to save coal. At present, Guangxi is fully rushing to import coal and coal from coal mines along Vietnam and Indonesia. In the past few days, Nanning citizens who walked to Nanhu Park in the evening found that the night view of the landscape around the park has been closed. In Nanning, the temperature of air conditioners in hotels, shopping malls, supermarkets, etc. should not be higher than 26 degrees Celsius, the elevators should be used in half, and the street lamps should be halved. Through the media, Guangxi Power Grid also appealed to the public to save electricity and share power shortages. In terms of energy conservation, the relevant person in charge of the Autonomous Region Industrial and Commercial Committee said that Guangxi will do everything possible to implement energy conservation and emission reduction, and allocate limited energy to industries with low energy consumption and high output.
The clutch release bearing is installed between the clutch and the transmission, the release bearing seat is loosely sleeved on the tubular extension part of the bearing cover of the first shaft of the transmission, the shoulder of the release bearing is always leaning on the release fork through the return spring, and retreats to the last position, and the end of the release rod (separation finger) keeps a clearance of about 3~4mm.
Due to the clutch compression. The release lever and the engine crankshaft run synchronously, and the release fork can only move axially along the clutch output shaft, and it is obviously impossible to directly use the release fork to toggle the release rod, and by separating the bearing, the release lever can be rotated while moving along the clutch output shaft, so as to ensure that the clutch can be smoothly engaged, the separation is soft, the wear is reduced, and the service life of the clutch and the entire drive train is prolonged.
performance
The clutch release bearing should be flexible in motion, without sharp sound or jamming, its axial clearance should not exceed 0.60mm, and the inner seat wear should not exceed 0.30mm
