The old building to be panned has been lifted by Baier hydraulic jacks to "vacant" both to protect the cultural relics and to meet the needs of construction. A cultural protection building in Xuzhou will be moved more than 240 meters away. A Republic of China building was panned. Yesterday, a reporter from Hyundai Express learned that the three-story old building had "vacated". In a few days, it will be relocated to a new site more than 240 meters away. The three-story Republic of China building to be translated as a whole is "Tongheyu ...
The hydraulic torque wrench is composed of a working head, a hydraulic pump and a high-pressure oil pipe. Through the high-pressure oil pipe, the hydraulic pump transmits power to the work head, and drives the work head to rotate or tighten the nut. The hydraulic pump can be driven by electricity or compressed air. The working head of a hydraulic wrench is mainly composed of three parts, the frame (also called the housing), the oil cylinder and the transmission parts. The output force of the oil cylinder, the piston rod of the oil cylinder and the transmission part form a motion pair. The distance from the center of the oil cylinder to the center of the transmission part is the arm of the hydraulic wrench to enlarge the force.
Recently, the Chenglan Railway-Bridge Structure Force and Deformation Test Project provided by the Bayer Group has successfully completed the first stage of the test. It has passed the preliminary review by the China Railway Corporation and obtained full affirmation and appreciation from the leaders of China Railway Corporation . In this test system, the accuracy error is controlled at ± 0.5mm. 45 jacks are divided into five layers and adjusted horizontally. The lifting displacement of each layer needs to be accurately controlled by a computer system, and various values are collected according to the force value and saved. Data, and ...
At present, the most prominent contradictions and problems in China's oil and gas industry are high market concentration and prominent monopoly phenomenon. This kind of monopoly exists not only in a certain link, but also in the entire industrial chain from upstream to downstream. According to the new idea of relaxing access from the entire industry chain, unlike the new power reform plan, which focuses on the middle and lower reaches in terms of liberalizing access, the reform of the oil and gas industry mainly focuses on easing access in the upper and middle reaches in order to seek for oil and gas exploration and production and An orderly competition pattern was formed in the import link, and oil was innovated in the upstream link ...
1. If there is runaway phenomenon during use by BAIER, you can first loosen the oil drain screw on the pump body, lift the pump body upright and hit it downwards a few times, then tighten the oil drain screw to continue using. 2. When using BAIER, do not add eccentric load or overload to avoid the danger of jack damage. When there is a load, do not remove the quick connector to avoid accidents and damage to the parts. 3. This machine uses oil as the medium. It is necessary to do the maintenance work of the oil and the machine to avoid blockage or oil leakage ...
Recently, a CNOOC oil refinery was equipped with hydraulic wrenches for new installations to make full safety preparations for the trial operation of new installations. As everyone knows, the hydraulic wrench industry is currently in a relatively chaotic state. Many small manufacturers or bag companies are impersonating big customers in the domestic market, causing many unsuspecting customers to suffer. Hydraulic torque wrenches, as equipment tools, have a high overall value, and the service life of their main core components can reach 8-10 years. The products of big brand companies are ...
