Canada hydraulic cylinder,hydraulic engineering cylinder manufacturer,hydraulic engineering cylinder
(Canada hydraulic engineering cylinder,produced by Hengyu Group）
hydraulic engineering cylinder are widely used in Canada，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed hydraulic engineering cylinder for customers from Canada.
hydraulic engineering cylinder buffer valve inspection and maintenance: For the valve buffer hydraulic engineering cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.
When the hydraulic engineering cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the hydraulic engineering cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.
When the hydraulic engineering cylinder is installed, the piston and the hydraulic engineering cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the hydraulic engineering cylinder head boss is easy to cause scars when it hits the inner surface of the hydraulic engineering cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized hydraulic engineering cylinders, only careful and careful operation can be avoided.
The role of the hydraulic engineering cylinder in the mold industry: the hydraulic engineering cylinder has a variety of uses in the mold, one is that the core distance is very large, or because of the mechanism of the product, only the hydraulic engineering cylinder is reasonable or more cost saving. Let the side core be extracted before opening the mold. Hot runner is mainly based on the product to decide, sometimes customers require the use of hot runner, the price is more expensive, but there are many benefits, you can save raw materials, shorten the molding cycle The hydraulic engineering cylinder has an irreplaceable role in the heavy industry production process: it is mainly used in places that need to support heavy objects for a long time, and it can still support heavy objects when the oil pressure is removed, and it is safe and reliable. Can be used underwater, single action, load reversion, nut self-locking to make the load safer, especially in large projects, is easy to operate control and self-locking jack, designed with a safety pressure retaining device, built-in pressure relief valve to prevent overload, to protect the self-locking jack to facilitate safe operation. The connection of the device is connected by high pressure hose and threaded joint, which has the advantages of fast use and overcoming the shortcomings of fast traditional joint oil leakage. It is mainly used for equipment installation and toppling operation in various industries such as electric power, construction, machinery manufacturing, mining, railway bridge, shipbuilding and so on.
How is the cylinder of hydraulic cylinder processed?
As the main parts of hydraulic cylinder, mining single pillar, hydraulic support, gun barrel and other products, its processing quality directly affects the life and reliability of the whole product. Cylinder processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of cylinder is deep hole processing, which has always troubled the processing personnel. Due to the residual compressive stress on the surface of the surface layer, the rolling machining is helpful to seal the small cracks on the surface and prevent the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the cylinder can be improved.
How to calculate cylinder pressure?
Hydraulic pressure area of cylinder × hydraulic pressure = output force of cylinder 200mm=20cm 100mm=10cm 15Mpa=150Kg/cm2 Cylinder thrust: 3.14×10×10 area ×150 pressure =47100Kg=47.1t cylinder pulling force: 3.14×(10×10-5×5) Area ×150 pressure =35325Kg=35.325t The above calculation did not consider the resistance of oil return, because you did not provide oil return pressure. But the impact should be small.
