(Congo tension cylinder,produced by Hengyu Hydraulic Co., Ltd）

tension cylinder are widely used in Congo，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed tension cylinder for customers from Congo.

Introduction to tension cylinder:

tension cylinder body inspection: The inner surface of the tension cylinder and the piston seal are the main factors causing the leakage in the tension cylinder, if the tension cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the tension cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

The role of the tension cylinder in the mold industry: the tension 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 tension 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 tension 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 quality of the tension cylinder can not be ignored in the purchase of the tension cylinder. The tension cylinder is the main component of the tension 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. tension 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 tension cylinder is deep hole processing, which has always troubled the processing personnel.

The tension cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the tension cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the tension cylinder wall due to the stiffness and the weight of the parts, causing scars.

Answers to some questions about tension cylinder:

Why is the hydraulic cylinder of the larger excavator arm upside down?
The weight of the excavating arm of a large excavator will be very heavy, and an oil cylinder has two cavities, one is a rod cavity, and the other is a rodless cavity. The lifting force of the excavator is the product of the ortho-projection area of the piston rod cavity by the oil pressure, so the strength of the rodless cavity is much greater than that of the rod cavity. And the parallel bars with the piston rod facing down are also conducive to assembly and future maintenance. So a large excavator has to keep the cylinder facing down.

100 tons press, the cylinder diameter is 250, how much pressure?
100 tons hydraulic press, if it is a single acting hydraulic cylinder, the required oil pressure is the nominal force divided by the cross-sectional area of the cylinder piston. One hundred tons of its pressure is 1000 kN (1000000N), the diameter of the cylinder is 250 mm, its area is the circular rate multiplied by the square of the radius, is 49062.5 square mm, and then the pressure divided by the area of the oil pressure is 20.38MPa. Therefore, a hydraulic pressure of 20.38 mpa is required for a 250 diameter cylinder to obtain 100 tons of pressure.
