(America pressure retaining cylinder,produced by Hengyu Group）

pressure retaining cylinder are widely used in America，because of excellent temperature resistance，no need for deceleration device，long service life.So our company has designed pressure retaining cylinder for customers from America.

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.

When using the pressure retaining cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the pressure retaining cylinder block. If the pressure retaining cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the pressure retaining cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the pressure retaining cylinder, so that the working efficiency of the pressure retaining cylinder is reduced.

The advantages and disadvantages of the pressure retaining cylinder: the surface of the pressure retaining cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the pressure retaining cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.

Repair method of small range wear of oil pressure retaining cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.

Answers to some questions about pressure retaining cylinder:

The inner diameter of the injection cylinder is 203.2mm and the diameter of the screw is 63.5mm. What is the enhancement ratio?
Oil pressure multiplied by the cross-sectional area of the cylinder is equal to the theoretical output force value, and then multiplied by the efficiency of the cylinder is equal to the actual output force value, and the oil pressure can be calculated by inverting the value input.

How big gear pump need to use for 60*100 cylinder?
One cylinder size alone does not determine the size of the pump used. Choose the size of the pump, at least to know 1, the size of the load is how much, by the size of the load and the size of the cylinder and other conditions can be calculated the pressure required by the hydraulic system. 2. Speed of operation. From this speed and cylinder size, the required flow rate of the system is calculated. The relevant parameters of the pump can be selected by the pressure and flow rate to determine what kind of pump is required.
