(Turkmenistan stainless steel cylinder,produced by Hengyu Group）
stainless steel cylinder are widely used in Turkmenistan，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed stainless steel cylinder for customers from Turkmenistan.
stainless steel cylinder use should try to avoid sealing belt into the stainless steel cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the stainless steel cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the stainless steel cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.
When installing the stainless steel cylinder pipe, the pipe should be cleaned after installation, and should not pass through the stainless steel cylinder block, and the by-pass pipe must be installed in front of the oil port of the stainless steel cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the stainless steel cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the stainless steel cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.
stainless steel cylinder and hydraulic station selection: Select the type and structure of the stainless steel cylinder according to the operation requirements of the main engine. According to the external load force borne by the stainless steel cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the stainless steel 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 stainless steel cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the stainless steel cylinder, the diameter of the piston and the piston rod.
In order to ensure the service life of the stainless steel cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.
What is the reason for the hydraulic cylinder sticking out and not retracting?
There are two reasons: First, the problem with the seal, if there are two seals on the piston, the top seal is broken. Second, when the hydraulic pressure itself is designed, the rod cavity area is too small, so that the desired return force can not be achieved during the return trip. You can first check whether the coupling is damaged; Then see if the relief valve in the oil line block is blocked. If the use time is too long, it needs to be cleaned, the hydraulic oil is very dirty and can block oil block. Electromagnetic directional valves can also be checked, but the chance of problems is relatively small, unless there is a product problem.
When the hydraulic cylinder changes from fast to slow, how can the slow speed become more even and the speed can be adjusted?
Reversing valve set 2 reversing valves. The back of one valve goes directly to the cylinder, running at full speed for fast action. Add a speed control valve behind the other valve, and then connect to the cylinder to achieve slow action, you can adjust the opening of the speed control valve, to achieve the speed of the cylinder can be adjusted. An import speed control valve to more than 1,000 yuan, if you think it is too expensive, you can also use the throttle valve instead. However, the throttle valve is greatly affected by the load change.
