What we need to know before buying an electric hydraulic jack from hydraulic jack manufacturers in china This is a more important point, because only when we understand, can we choose an electric hydraulic jack that suits our needs. What do we need to know? What about the content?
1.You need to know the scope of work you need to use and the environment of the site; 2. You need to know whether the weight of the job is to be lifted by an electric hydraulic jack or push-pull work, and the length (distance) of the jacking (push-pull); 3. Need Know whether the power supply at the work site is three-phase or two-phase; 4. Need to know the fixing method of the hydraulic cylinder of the electric hydraulic jack and the placement and distance length of the cylinder and the hydraulic pump; 5. Need to know the electric hydraulic jack Personnel control mode (operation close to or away from the electric hydraulic jack);
Electric hydraulic jacks have many advantages. The buffer device and exhaust device of the large-tonnage hydraulic jack depend on the specific application, and other devices are essential. The output force of a large-tonnage hydraulic jack hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between both sides; the hydraulic cylinder is basically composed of a cylinder tube and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device.
Suitable for various occasions. On the basis of ordinary electric hydraulic jacks, we invented large-tonnage hydraulic jacks, freeing hands and making work easier. The emergence of electrical equipment has changed people's lives. Since Watt invented the first steam engine, we have entered the industrial age, and our lives have become more and more convenient. We invented the car as a walking tool, we invented the telephone for long-distance communication, the Internet allows us to understand the other side of world life, and we even invented the spacecraft to explore the galaxy.
Now our lives are changed by various electronic devices. Some of our dangerous jobs and boring repetitive jobs are all done by machines. The buffer device and exhaust device of the large-tonnage hydraulic jack depend on the specific application, and other devices are essential. Take the electro-hydraulic jack we use as an example. We invented large-tonnage hydraulic jacks to make work easier. Let it help us work and make us more efficient.
The large-tonnage hydraulic jack adds an electric pump to the original electric hydraulic jack. Generally speaking, large-tonnage hydraulic jacks free our hands. We don't need to rely on our hands to keep working to generate stress. We only need to press a button to make the device work by itself. For us, this is more labor-saving.
The hydraulic jack manufacturers in chinaproduces such products to meet our needs.
The working efficiency of large-tonnage hydraulic jacks is also higher than that of ordinary electric hydraulic jacks. After all, our hands are still inferior to mechanical equipment (composition: drive, gear, etc.). Therefore, large-tonnage hydraulic jacks can be said to be more and more effective for our work. There are many unexpected situations at work. With large tonnage hydraulic jacks, we can stay away from the scene and observe from a distance. Security is high.
Things to consider when choosing a hydraulic jack of welding jack manufacturers in china: The type of hydraulic jack. Different types of hydraulic jacks are used in different operating situations. There are many types of jacks, such as bridge jacks, mining jacks, etc. Customers should choose the type suitable for use according to the actual operating situation; the specifications of the hydraulic jack. Choose the appropriate specifications according to the tonnage of the lifted heavy objects. Do not use small-tonnage hydraulic jacks to lift large-tonnage heavy objects. It is easy to damage the hydraulic jack.
Do not use hydraulic jacks for overloading. For example, in bridge construction, if you lift a 10-ton bridge, try to choose high-tonnage jacks, which can be used for a long time without overloading. Understand the limits of the scope of use of hydraulic jacks, hydraulic jacks are not always available, so the model you choose depends on your own construction situation. During the operation, there must be a dedicated technician to guide the operation to ensure the smooth completion of the work.
The reason why the base of the hydraulic jack must be firm: All the forces are applied except the piston cylinder of the hydraulic jack to lift, but the base is receiving all the forces, so the base needs to be firmly placed; if the base of the machine is not stable, it will cause construction It will cause tilt; note that there is an oil valve on the base, so its stability is also related to the influence of the oil valve; pay attention to the position of the base of the hydraulic jack to be flat, if it is not flat, a flat plate pad should be used. The hydraulic jack manufacturers in china sometimes explains such situations.
