France double rod cylinder,double rod cylinder manufacturer

France double rod cylinder

(France double rod cylinder,produced by Hengyu Hydraulic Cylinder Factory)

double rod cylinder are widely used in France,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed double rod cylinder for customers from France.

Introduction to double rod cylinder:

If it is found that the double rod cylinder lubrication is poor or the double rod cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the double rod cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the double rod cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the double rod cylinder center line. In this way, when the piston works in the double rod cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the double rod cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

The double rod cylinder should be vented: when the double rod cylinder is installed or parked for a long time to work again, the air will penetrate into the double rod cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the double rod cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the double rod cylinder, the oil is best entered and discharged from the highest point of the double rod cylinder. double rod cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

double rod 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 double rod 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 main role of the double rod cylinder: the double rod cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the double rod cylinder realizes reciprocating motion. The structure of the double rod cylinder has three categories: piston double rod cylinder, plunger double rod cylinder, swing double rod cylinder, piston double rod cylinder and plunger double rod cylinder to achieve reciprocating linear motion, output speed and thrust, swing double rod cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the double rod cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The double rod cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

Answers to some questions about double rod cylinder:

Is there a way to make the cylinder stop pushing when it hits something hard during the process of pushing?
The simplest solution is to press the stop switch, this switch has a mechanical type, touch the object on the action or send a stop signal, through the operation of the motor control cylinder; There is also an induction switch, that is, when the hydraulic cylinder expands to the range of the induction switch can sense the signal, it sends a signal to let the motor act, resulting in the corresponding action of the cylinder.

Is rubber or polyurethane better for V-ring of hydraulic cylinder?
The hydraulic cylinder V-type seal ring is better with polyurethane, and chlorine rubber is used for various chemicals and high temperatures, especially when there are wear-resistant requirements, polyurethane rubber is needed. But the price of polyurethane rubber is much more expensive than the price of rubber. However, the V-ring material is most commonly used in nitrile and neoprene rubber, and natural rubber is used for sealing water and air. Butyl rubber is used for non-combustible hydraulic fluids and phosphate ester hydraulic fluids. The advantage is that the price is cheaper than the polyurethane material, and the disadvantage is that it is not wear-resistant and the anti-aging property is relatively poor.
