(Reporter Shi Baohua) The statistics report released by the National Bureau of Statistics yesterday showed that car production rebounded in November, and the monthly output was the highest since July. Auto companies, on the other hand, have fallen into a passive position of increasing production without increasing income. In November, the profit of the automobile industry continued to drop significantly, and it was already on the verge of a loss in the entire industry. In November, a total of 186,000 sedan cars were produced in the country, a decrease of 5.7% from the same month of last year, and the decline was slower than in previous months. In March of this year, the country’s monthly production of cars reached the highest level of 245,200 units this year, and then began to decline. The monthly output fell to 21.61 million units in June, and fell to 200,000 units in July, dropping sharply to 170,400. From the perspective of sales, sales of national car companies in November increased by 3.7% year-on-year, and sales in the Beijing auto market, which accounted for more than 10% of the country's passenger car market, were still declining. In particular, new car sales fell by more than 30% year-on-year. According to relevant sources in the National Statistics and Public Transportation Division, near the end of the year, car manufacturers have significantly increased their efforts to transfer inventory to dealers in order to complete the annual production and sales targets. In particular, in late November, 12 major auto makers concentrated sales to dealers. With 50% of the monthly production, market sales to end-users have not changed significantly. This will have a negative impact on the improvement of the sales situation next year. In addition, the current end-users are in a state of holding money, mainly because the car price cuts are too fast, and consumers feel that there is no stable price expectation. At the same time, the implementation of the two new policies at the beginning of next year will also affect consumer expectations for vehicle prices: First, the cancellation of import vehicle licenses and import car quotas; the other is the reduction of tariffs. As a result, consumers are expecting declining car prices to decline next year.
Excavator Cylinder Piston Rod Seals
Installation and application of piston rod seal for excavator hydraulic cylinder
The installation and application of hydraulic cylinder piston rod seals in excavators mainly include the following aspects:
1. Applying lubricating oil: Before installing the seal, the surface of the piston rod must be coated with lubricating oil to facilitate the installation and use of the seal.
2. Install the seal: Install the seal on the piston rod in sequence, taking care not to pinch or bend the seal.
3. Pressing the seal: After installing the seal, special tools need to be used to press the seal tightly to ensure its tightness and stability.
4. Check the sealing effect: After installing the sealing element, it is necessary to check the sealing effect. It can be detected by observing the working status of the hydraulic cylinder or using tools such as leak detectors.
5. Application scenario: The piston rod seal of excavator hydraulic cylinder is mainly used in the hydraulic system of construction machinery such as excavators, loaders, and bulldozers to prevent hydraulic oil leakage and ensure the normal operation of the machine.
In summary, the installation and application of hydraulic cylinder piston rod seals in excavators is a very important part of the hydraulic system, and must be strictly operated in accordance with regulations to ensure the normal operation and safety of the machine.
