(hydraulic press cylinder,produced by Hebei Hengyu company)

hydraulic press cylinder are widely used ,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed hydraulic press cylinder for our customers.

Introduction to hydraulic press cylinder:

Do not enter foreign bodies when installing the hydraulic press cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.

The quality of the hydraulic press cylinder can not be ignored in the purchase of the hydraulic press cylinder. The hydraulic press cylinder is the main component of the hydraulic press 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 press 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 press cylinder is deep hole processing, which has always troubled the processing personnel.

When the long-stroke hydraulic press cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in hydraulic press cylinder head seal damage, oil leakage, and piston sleep in the hydraulic press cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the hydraulic press cylinder; The piston and the piston rod are connected with a spherical joint.

hydraulic press 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 hydraulic press cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the hydraulic press cylinder. c. The hydraulic press cylinder seal is extruded, if the O-ring is obviously extruded at the hydraulic press cylinder seal, replace the hydraulic press cylinder seal.

Answers to some questions about hydraulic press cylinder:

Why the cylinder cannot operate normally after the explosion-proof valve is installed?
The pipeline explosion-proof valve is specially designed to prevent pipeline damage and free fall of the cylinder, so there must be back pressure to open. If there is no oil return pressure, or the oil return pressure is too small, and can not adjust the oil return pressure, such a system with explosion-proof valves is more troublesome, it is recommended to add a one-way throttle valve between the cylinder and the tank to establish back pressure. If you understand the explosion-proof valve, you can also try to adjust the opening of the valve (that is, the flow of the regulating valve), and adjust the opening to help the valve to open.

In hydraulic equipment, is the motor power related to the cylinder pressure holding time?
Irrelevant. The motor only drives the plunger in the hydraulic cylinder of the oil pump to extend out, and stops when the set pressure is reached; The length of the pressure holding time is related to the sealing degree of the hydraulic cylinder and the solenoid valve.
