According to reports, the Pagoda Group has conducted extensive research and investigations on dimethyl ether technologies and markets at home and abroad, and exchanged views with well-known scientific research institutions at home and abroad. Finally, Southwest Branch and Tianke Group were recognized for their advanced, reliable and mature technologies. . The project is expected to invest 120 million yuan, plans to put into operation by the end of 2008.
The project will use methanol gas-phase catalytic dehydration method to make dimethyl ether, with a unique vaporization decanter structure and a simple process design of the separation process, which can save 30% of investment, and can greatly reduce energy consumption, so that the steam consumption per ton of product than The domestic and foreign devices of the same type are 0.5 tons lower; with self-developed catalysts, the selectivity of methanol to dimethyl ether will reach 99.5% or more, and it can basically reach no exhaust emissions, and the methanol consumed per ton of product will be reduced.
More than 10 years ago, the Southwestern Institute took the lead in the establishment of several sets of gas-phase methanol-dehydrated kiloton-grade aerosol-grade and 10,000-ton-grade fuel-grade dimethyl ether industrial plants in companies such as Guangdong Zhongshan Fine Chemicals Co., Ltd., currently using Southwestern Institute and Tianke Group. The invention patent technology of ether has established more than 40 sets of dimethyl ether devices at home and abroad, and all technical and economic indicators meet or exceed design requirements. The dimethyl ether content is 99% to 99.9%, and the product yield is as high as 98%.
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.
Ningxia will build 400,000 tons of dimethyl ether industrial device
On January 29, the signing ceremony of the contract for the contract for the two invention patent technologies and engineering designs by the Southwest Research and Design Institute of Chemical Engineering and Sichuan Tianyi Science and Technology Co., Ltd. and the 400,000-ton/year DME industrial device built in Ningxia Baota Group was held in Chengdu. Held. This is currently the world's largest gas-phase dimethyl ether industrial plant, marking a new breakthrough for China in this field. Large-scale production will play an important role in promoting the large-scale promotion of dimethyl ether.
