(El Salvador accumulator hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

accumulator hydraulic cylinder are widely used in El Salvador，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed accumulator hydraulic cylinder for customers from El Salvador.

Introduction to accumulator hydraulic cylinder:

When the accumulator hydraulic cylinder is installed, the piston and the accumulator hydraulic cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the accumulator hydraulic cylinder head boss is easy to cause scars when it hits the inner surface of the accumulator hydraulic cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized accumulator hydraulic cylinders, only careful and careful operation can be avoided.

When the oil pressure of the accumulator hydraulic cylinder inlet is too low to reach the specified value, the leakage situation of the relevant oil system should be checked and the leakage should be eliminated; Check the piston and piston rod seal ring for damage, aging, loose and other phenomena; Check whether the hydraulic pump and pressure valve are faulty.

When the accumulator hydraulic cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the accumulator hydraulic cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil accumulator hydraulic cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical accumulator hydraulic cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the accumulator hydraulic cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

The coordination of the sliding parts of the accumulator hydraulic cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

Answers to some questions about accumulator hydraulic cylinder:

Hydraulic cylinder performance requirements?
Hydraulic cylinder performance requirements: hydraulic cylinder is the hydraulic system to achieve energy transfer, conversion and control of the working medium, in addition, it is also responsible for the lubrication of the system, rust prevention, corrosion prevention and cooling. The performance of hydraulic oil will make the system flexible, accurate and reliable. Hydraulic performance requirements are determined according to the design parameters of the hydraulic system, operating conditions, the structure of the hydraulic pump and the working environment. Appropriate viscosity and good viscosion-temperature performance Viscosity is an important performance indicator of hydraulic pressure, which has an important impact on the smooth operation of the hydraulic system and the friction parts. The low temperature performance of hydraulic oil includes three aspects: low temperature flow, low temperature start-up and low temperature pumping.

How to calculate the tonnage of hydraulic cylinder? The tonnage of the cylinder refers to the output force of the cylinder under rated working pressure: 1, for single rod piston hydraulic cylinder, it can be calculated by the area of the circle corresponding to the inner diameter of the cylinder A (square centimeter), and the rated working pressure of the system p (mpa), the value is equal to 10pA kg force, and the ton is 0.01pA. 2, for the double rod piston hydraulic cylinder, with A(square centimeter) to indicate the cylinder cylinder diameter and piston rod outer diameter defined by the ring area, with p (mpa) to indicate the rated working pressure of the system, the output force of the cylinder is 0.01pA ton force.
