Dominica hydraulic cylinder,hydraulic engineering cylinder manufacturer,hydraulic engineering cylinder
(Dominica hydraulic engineering cylinder,produced by Hebei Hengyu company）
hydraulic engineering cylinder are widely used in Dominica，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed hydraulic engineering cylinder for customers from Dominica.
The quality of the hydraulic engineering cylinder can not be ignored in the purchase of the hydraulic engineering cylinder. The hydraulic engineering cylinder is the main component of the hydraulic engineering cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. hydraulic engineering cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of hydraulic engineering cylinder is deep hole processing, which has always troubled the processing personnel.
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.
The coordination of the sliding parts of the hydraulic engineering cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.
When the hydraulic engineering cylinder needs to be stored for a period of time, please follow the recommended methods: The hydraulic engineering cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the hydraulic engineering cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil hydraulic engineering cylinder should not be in direct contact with water vapor for a long time. The hydraulic engineering cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the hydraulic engineering cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the hydraulic engineering cylinder Before working, the hydraulic engineering cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the hydraulic engineering cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.
Why is a light cylinder less productive than a heavy cylinder at the same oil pressure?
f=ps Under the same pressure, the larger the area, the greater the output, but the maximum pressure can not exceed the system engineering pressure of the cylinder!
What is the cylinder with rod cavity, what is the rodless cavity.
The rod cavity is the end of the piston rod, the rodless cavity is the end without the piston rod.
