America press machine hydraulic cylinder

(America press machine hydraulic cylinder,produced by Hebei Hengyu company)

press machine hydraulic cylinder are widely used in America,because of no transmission clearance,powerful torque,excellent temperature resistance.So our company has designed press machine hydraulic cylinder for customers from America.

Introduction to press machine hydraulic cylinder:

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

When the piston speed of the press machine hydraulic cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the press machine hydraulic cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

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

press machine hydraulic 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 press machine hydraulic 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.

Answers to some questions about press machine hydraulic cylinder:

Can the hydraulic oil in the cylinder return to the tank?
Yes, there is a way, for example, first remove the cylinder from the machine, and then connect the two pipes on the cylinder, so that the cylinder piston rod is completely retracted into the cylinder, at this time, the piston is with the bottom, and the rear chamber is almost no oil, and then screw off the joint at the end of the front chamber by the hydraulic station, and put it in an empty bucket. Finally, insert the gas pipe into the oil port of the rear chamber. Open the air source, and then the rod will run out, and you'll drain the hydraulic oil from the end of the rod, which requires a source of air on site.

How to calculate the inner diameter of the hydraulic cylinder?
These two parameters need the following information to decide: 1, pump displacement, speed (to get the actual output flow of the pump) 2, three and time requirements (lift time, drop time takes a few seconds) and then view the close cylinder series according to the results. Select the right cylinder.
