All related companies of Sinopec are fully committed to combating snow and ice disasters
Since mid-January, in some parts of China, there have been rare extreme temperatures, rain, snow, and freezing extreme weather that have rarely been seen since the founding of the People's Republic of China. All relevant Sinopec enterprises urgently initiated emergency plans to fight ice and snow disasters and ensure safe production and market supply.
Since mid-January, Hunan province has experienced freezing weather. Hunan Petroleum Branch immediately launched an emergency plan to ensure the safety of personal, warehouse, capital, and oil supply. The company provided first-line employees with anti-skid shoes, earmuffs and gloves, and ensured that the grassroots employees had hot meals. On the one hand, they set up a special inspection team to carry out special safety inspections such as anti-freezing, anti-coagulation, and fire prevention on a pipe-by-valve, valve-by-machine, and machine-by-machine basis. On the other hand, in order to ensure oil supply during the Spring Festival, the company balances resource allocation and ensures reasonable inventory. The gas stations in the entire highway, central city, and major road sections will supply oil products 24 hours a day.
Since January 11, low-temperature freezing weather has hit the Hubei region. Jingmen Petrochemical started the emergency plan for preventing ice and snow in a timely manner, so that the equipment has withstood the test of prolonged freezing weather, and the safety production has remained good. The company organizes personnel to carry out heat insulation of the gas system, hydrogen system and waste oil system. At the same time, production workshops and inspection and repairing units launched a comprehensive investigation, dealt with the frozen equipment in a timely manner, and imposed a system for listing equipment that could not be processed. They also bought back a batch of industrial salt and sprinkled salt and snow on the main roads in the production and living areas to facilitate cadres and employees to work and ensure the safety of vehicles entering the factory area.
Since January 12, the Jiangsu oil field has been continuously attacked by Blizzard. The snow, which is more than 40 centimeters thick, covers the Baili oil area. The oilfield immediately initiated an emergency plan for disaster prevention, and the oil and gas party and government leaders shunted down to the oil field to direct the command. Hundreds of emergency commandos were dispatched in a timely manner, focusing on the construction work units in the field to do all kinds of preventive work. The oil production teams intensified production site management, reinforced the oil platform vulnerable to blizzard attacks, and employees were patrolling the pumping units and major crude oil gathering and transportation pipelines with knee-deep snow. As of January 28, although heavy snow is still falling, the wells of 1,692 oil wells in the entire oil field have exceeded 95%, and the daily output of crude oil is 4615 tons, which is 89% of the planned month.
Since January 12, three snowfalls in the province have occurred continuously in Anhui Province. Anqing Petrochemical has performed anti-freezing, anti-skid, anti-icing and anti-coagulation work in the installation area, and has conducted high-voltage cables, overhead pipelines, oil pipelines, and groundwater pipelines. And other key prevention areas will carry out major inspections; emergency procedures shall be formulated for the entry of crude oil and raw material coal into the factory and products, so as to ensure orderly production and operation. At the same time, it also makes full use of media such as television, newspapers, and the Internet to do a good job in information transfer, security, and prompting to ensure that the snow-relief work is absolutely safe.
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.
