Angola tension cylinder

(Angola tension cylinder,produced by Hengyu Hydraulic Cylinder Factory)

tension cylinder are widely used in Angola,because of no need for deceleration device,long service life,smooth movement.So our company has designed tension cylinder for customers from Angola.

Introduction to tension cylinder:

Regular maintenance of the tension cylinder includes: regular tightening, tension cylinder fastening screws and gland screws, tension 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 tension cylinder once a year. Clean regularly, the tension cylinder is cleaned every other year, and the seals are replaced while cleaning.

tension cylinder and hydraulic station selection: Select the type and structure of the tension cylinder according to the operation requirements of the main engine. According to the external load force borne by the tension cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the tension cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the tension cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the tension cylinder, the diameter of the piston and the piston rod.

The tension cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the tension cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the tension cylinder wall due to the stiffness and the weight of the parts, causing scars.

If air enters the hydraulic system, the tension cylinder will not operate normally, mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced.

Answers to some questions about tension cylinder:

Is there a national standard for the testing of hydraulic cylinders?
Generally speaking, the cylinder test is carried out according to JB/JQ20302 Allowable leakage of cylinder in pre-factory leakage test. GB2879 hydraulic cylinder piston and piston rod dynamic seal groove type, size and tolerance. GB6578 hydraulic cylinder piston rod dust ring groove type, size and tolerance. GB7938 hydraulic cylinder and cylinder nominal pressure series, etc.

What is the main maintenance of the cylinder?
After disassembling the cylinder: 1, clean the cylinder and piston; 2, replace all seals; 3, if there is a valve to repair, to ensure sealing and flexible; 4, deal with all deformation parts; 5. Installation experiment.
