Peru hydraulic cylinder,stroke adjustable cylinder manufacturer,stroke adjustable cylinder

(Peru stroke adjustable cylinder,produced by Hebei Hengyu company）

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

Introduction to stroke adjustable cylinder:

stroke adjustable cylinder installation precautions: Before installing the stroke adjustable cylinder into the system, the parameters on the stroke adjustable cylinder label should be compared with the parameters when ordering. The base of the stroke adjustable cylinder must have sufficient stiffness, otherwise the stroke adjustable cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

The meaning of the stroke adjustable cylinder model marked by the stroke adjustable cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the stroke adjustable cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the stroke adjustable cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

stroke adjustable cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the stroke adjustable cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the stroke adjustable cylinder. c. The stroke adjustable cylinder seal is extruded, if the O-ring is obviously extruded at the stroke adjustable cylinder seal, replace the stroke adjustable cylinder seal.

When the hydraulic oil is not pumped into the stroke adjustable cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the stroke adjustable cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

Answers to some questions about stroke adjustable cylinder:

What is the role of the cylinder on the plastic mold? The oil cylinder plays a great role in the mold, one is that the core distance is very large, or because of the mechanism of the product, only the oil 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, sometimes customers require to use hot runner, the price is more expensive, but there are many benefits. It can save raw materials and shorten the molding cycle.

How to choose cylinder size, pump type, motor power for a 30-ton press?
30 tons = 30,000 kg. It is expected to use a 16 mpa oil pump, then the cylinder area =30000/(160x3.14) and then square, the cylinder bore is 150 mm. Calculated at 500 mm travel per minute, the flow rate per minute is :0.75^2x3.14x5=8.8 liters/minute. Motor power =8.8x16/60=2.355. A 9 L/min, 16 mpa pump is available. Piston diameter 150 mm cylinder. 3 kW motor.
