Republic of Lithuania hydraulic cylinder,tension cylinder manufacturer,tension cylinder(Republic of Lithuania tension cylinder,produced by Hebei Hengyu company)
tension cylinder are widely used in Republic of Lithuania,because of simple structure and reliable operation,excellent temperature resistance,no transmission clearance.So our company has designed tension cylinder for customers from Republic of Lithuania.
Causes and countermeasures of oil tension cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the tension cylinder will lead to premature wear of the piston seal, replace the piston seal; If the tension cylinder is visibly scarred, the tension cylinder must be replaced. It can be pressurized at one end of the tension cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most tension cylinder piston drift may not come from the tension cylinder, the above method to determine the tension cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.
When the tension cylinder is installed, the piston and the tension 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 tension cylinder head boss is easy to cause scars when it hits the inner surface of the tension 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 tension cylinders, only careful and careful operation can be avoided.
The cavitation of the tension cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the tension cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.
The repair method of the tension cylinder: the repair of the tension cylinder must use brush plating. This is because this repair method can be carried out on site, and the repair effect is good. In this way, loading and transportation can be eliminated to shorten the repair time and improve work efficiency. In addition, the coating obtained by brush plating has good binding force and will not have obvious boundaries. Moreover, the repair surface has high hardness and good wear resistance.
Why manual forklift oil cylinder can not lift up?
Manual hydraulic forklift truck often can not be pressed up, there are several reasons: for manual hydraulic truck: 1) There is no hydraulic oil 2) the purity of the oil is not enough 3) the adjusting bolt is too close or the adjusting screw is too tight, so that the valve is always open, 4) there is an air in the hydraulic cylinder. Method: 1) Refueling 2) Oil change 3) air discharge. For manual hydraulic stacker, also called manual lift car 1) Less than the amount of oil 2) impurities in the hydraulic oil, so that the check valve can not be closed. Method 1) Add enough hydraulic oil 2) Remove the cylinder, screw off the bottom plate, remove the impurities in the bottom plate.
How to calculate the inner diameter of the hydraulic cylinder?
These two parameters need the following information to decide: 1, pump displacement, speed (to get the actual output flow of the pump) 2, three and time requirements (lift time, drop time takes a few seconds) and then view the close cylinder series according to the results. Select the right cylinder.
