(Belarus stainless steel cylinder,produced by Hengyu Hydraulic Co., Ltd）
stainless steel cylinder are widely used in Belarus，because of long service life，smooth movement，high work efficiency.So our company has designed stainless steel cylinder for customers from Belarus.
When the stainless steel cylinder is installed, the piston and the stainless steel 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 stainless steel cylinder head boss is easy to cause scars when it hits the inner surface of the stainless steel 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 stainless steel cylinders, only careful and careful operation can be avoided.
1, the hydraulic machinery should be kept clean, in order to prevent dust and debris from falling into the oil, the tank should be sealed. 2, the oil in the tank should be replaced regularly according to the working condition. When changing the oil, the dirt and impurities accumulated at the bottom of the tank should be removed and the tank should be cleaned. 3, hydraulic oil, oil drums should be set in a clean and safe place to strengthen management. The oil drum, oil filter, oil funnel, oil pipe, etc. used should be kept clean. The oil drums for loading hydraulic oil must be cleaned in advance, and the oil drums should be dedicated and not mixed with other oil drums.
When installing the stainless steel cylinder, the axial ends of the stainless steel cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the stainless steel cylinder, there is axial expansion. If the two ends of the stainless steel cylinder are fixed, all parts of the stainless steel cylinder will be deformed. When disassembling the stainless steel cylinder, it is strictly forbidden to hammer the stainless steel cylinder and the piston surface, such as the stainless steel cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.
stainless steel cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.
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.
Why does the tipping bucket cylinder have a cylinder withdrawal problem?
This problem may have a certain relationship with the operation of the driver, the main reasons are the following two situation analysis: 1, the current domestic loader working device is mostly a six-link mechanism, the six-link mechanism in the bucket to the limit position, lift the boom, the rotating bucket cylinder will appear "cylinder pulling" phenomenon, that is, the piston rod of the rotating bucket cylinder will be pulled out. In this case, in order to protect the cylinder, a pressure overload protection valve with large and small cavities is provided on the multi-way valve rotating bucket link (large chamber 18MPa, small chamber 12MPa). 2, before the cylinder is assembled to the whole machine, the cylinder is not limited, the piston rod of the cylinder can be pulled in place before and after, but when it is installed on the whole machine, in order to avoid the cylinder pulling out, the limit switch is installed according to the regulations.
