Nepal hydraulic cylinder,supporting cylinder manufacturer,supporting cylinder

(Nepal supporting cylinder,produced by Hebei Hengyu company）

supporting cylinder are widely used in Nepal，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed supporting cylinder for customers from Nepal.

Introduction to supporting cylinder:

The role of the supporting cylinder in the mold industry: the supporting 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 supporting 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 supporting 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.

supporting cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the supporting cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

The supporting cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.

The supporting cylinder should be used correctly and maintained regularly. The supporting cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the supporting cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.

Answers to some questions about supporting cylinder:

How to distinguish cylinder rod head and cylinder bottom?
One end of the piston rod can be telescopic is the rod head, and the one behind is the bottom of the cylinder, which is the single rod cylinder.

What is a mold core cylinder?
Simple plastic parts can be directly pushed out by the ejector rod after injection molding, complex plastic parts can not be directly pushed out by the ejector rod after injection molding, to make the interference part active, control its position through the cylinder (injection molding into the mold, so that the shape of the plastic parts meet the demand, exit after opening the mold, so that the plastic parts are smoothly pushed out), This kind of cylinder is the mold core cylinder.
