What are the uses of hydraulic jacks
 hydraulic jacks have a variety of names. As a china supplier, Now let's understand the uses of hydraulic jacks:
 1. Single-acting hydraulic jack is a general type, which can be used in equipment maintenance, installation and conventional industrial production. Single-acting hydraulic jack has a wide range of travel length and lifting capacity, which is the choice of maintenance, manufacturing, construction and other operations. All models can design neck threads and bottom mounting holes, making the matching  installation and positioning convenient.           
 2. Thin jacks have smaller volume and can produce greater working capacity. They are especially used in narrow space, and have many functions such as lightweight, flexible and high jacking force. This product is widely used in power, chemical industry, steel, ship manufacturing and maintenance, bridges, construction, mining, iron and steel works, oil fields and machinery. Machinery and other enterprises, and play its infinite power.           
 3. Dual-acting hydraulic jack is suitable for high-tonnage lifting operation, which requires precise control of object lifting and maintenance. In horizontal slip installation of tunnel pipeline, its hydraulic reset design can quickly and effectively retract the piston back to its original position, and prepare for the next pipe.           
 4. Single-acting hollow jack products are suitable for cable and anchor bolts, tension test and maintenance of stress screw and application occasions requiring tension force. Single-acting hydraulic cylinder has unique hollow piston design, allowing solid rod or steel rope to penetrate, providing tension force, and selecting steel piston saddle can also be used as ordinary jack. For post-tensioning and pre-tensioning operations.           
 5. Ultra-high pressure synchronous jack is widely used in large-scale construction equipment, synchronous lifting and adjustment of components and erection of railway, highway and bridge projects. Safety pressure retaining device is designed, built-in pressure relief valve prevents overload and protects jack for safe operation. It also designs several groups of synchronous distribution valves, which can control jack synchronous lifting and lowering at any time. The device is connected by high pressure rubber hose and threaded joint, which has the advantages of safety and convenience, and overcomes the shortcomings of oil leakage of traditional fast joint.
 Now let's talk about the main points of using hydraulic oil rationally.           
 (1) Hydraulic Jack should be cleaned before oil change. Hydraulic Jack must be cleaned thoroughly before using hydraulic oil for the first time. When replacing the same kind of hydraulic oil, it should also be flushed with new hydraulic oil for 1-2  times.           
 (2) Hydraulic oil should not be mixed at will. If a certain brand of hydraulic oil has been selected, it must be used separately. Without the consent of the manufacturer of hydraulic equipment and without scientific basis, it is not allowed to mix with hydraulic oils of different viscosities, or with hydraulic oils of the same viscosities, but not from the same manufacturer, let alone with other types of oils.           
 (3) Pay attention to the good sealing of hydraulic jack. Hydraulic jacks using hydraulic oil must be kept strictly sealed to prevent leakage and mixing with various external water and dust media.           
 (4) Change the hydraulic oil in time according to the oil change index. Hydraulic oil in hydraulic equipment should be sampled and tested regularly. Once the physical and chemical indexes of oil reach the oil change index (single or several of them reach), the oil change index based on the oil change index should be replaced with 10-22 oil change index. It is a scientific oil exchange cycle.
