pressure retaining cylinder Sold to Cote d 'Ivoire

This article mainly introduces:

Cote d 'Ivoire hydraulic cylinder,pressure retaining cylinder manufacturer,pressure retaining cylinder

(Cote d 'Ivoire pressure retaining cylinder,produced by Hengyu Group）

pressure retaining cylinder are widely used in Cote d 'Ivoire，because of no need for deceleration device，high work efficiency，excellent fatigue and impact resistance.So our company has designed pressure retaining cylinder for customers from Cote d 'Ivoire.

Introduction to pressure retaining cylinder:

Regular maintenance of the pressure retaining cylinder includes: regular tightening, pressure retaining cylinder fastening screws and gland screws, pressure retaining cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the pressure retaining cylinder once a year. Clean regularly, the pressure retaining cylinder is cleaned every other year, and the seals are replaced while cleaning.

If the seal of the pressure retaining cylinder is softened and sticky, it may be that the seal is incompatible with the hydraulic oil or the nearby lubricating oil, replace the appropriate seal; If the seal becomes hard and loses elasticity, most of it is because the ambient temperature is too high (more than 80 ° C), make appropriate temperature insulation protection or replace the high temperature seal.

In the process of using the pressure retaining cylinder, sometimes such a problem will occur, the pressure retaining cylinder can not act immediately after the instruction of the pressure retaining cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil pressure retaining cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

When the pressure retaining cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.

Answers to some questions about pressure retaining cylinder:

How to calculate multistage cylinder volume?
When the multi-stage cylinder is extended, the largest cylinder is extended first, and when the largest cylinder stroke is completed, the second largest cylinder is extended again, the second largest cylinder stroke is completed, the third largest cylinder is extended again... Therefore, the cylinder extension length is less than the stroke of the largest cylinder, and the volume is the extension length times the inner hole area of the largest cylinder. The cylinder extension length is greater than the maximum cylinder stroke and less than (the largest cylinder stroke + the second largest cylinder stroke), and the volume is the largest cylinder stroke times the internal hole area of the largest cylinder + (the extension length - the largest cylinder stroke) times the second largest 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.
