(Canada large hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to large hydraulic cylinder:

Repair method of small range wear of oil large hydraulic cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.

large hydraulic cylinder piston rod material introduction: In general, we use 45 steel to produce large hydraulic cylinder piston rod. It has a large impact force when it is used, and some good performance steel are also used in the heavy load transmission. In order to have enough work intensity when using, and can ensure normal use, this is still more critical to have a detailed understanding of the material.

When the large hydraulic cylinder is installed, the piston and the large 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 large hydraulic cylinder head boss is easy to cause scars when it hits the inner surface of the large 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 large hydraulic cylinders, only careful and careful operation can be avoided.

If the seal of the large hydraulic cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and large hydraulic cylinder, and the phenomenon of "pulling the large hydraulic cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.

Answers to some questions about large hydraulic cylinder:

How do hydraulic equipment and hydraulic cylinders maintain a certain pressure after pressing to a certain position?
There are several methods. 1. You can use a constant pressure variable pump to adjust the control pressure of the pump to the pressure required by the cylinder, so that when the cylinder is in place, the pump uses the minimum flow rate to maintain the pressure, and the system is more energy saving. 2. If the pressure is maintained for a short time, a hydraulic control check valve can be added to the oil inlet end of the cylinder to close the cylinder and maintain the pressure. If the volume of the cylinder is large, an accumulator can be added between the valve and the cylinder to maintain pressure for 10-30 minutes. 3. You can add a small flow pump, the large pump after unloading, the small pump has been running, specifically for maintaining pressure.

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.
