(Dominica self-locking hydraulic cylinder,produced by Hengyu Group）
self-locking hydraulic cylinder are widely used in Dominica，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed self-locking hydraulic cylinder for customers from Dominica.
self-locking hydraulic cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the self-locking hydraulic cylinder head itself is the guide sleeve of the piston rod, the self-locking hydraulic cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the self-locking hydraulic cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.
The scar on the sliding surface of the self-locking hydraulic cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the self-locking hydraulic cylinder wall. Therefore, before installation, these scars must be fully repaired.
If the seal of the self-locking 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 self-locking hydraulic cylinder, and the phenomenon of "pulling the self-locking 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.
Causes and countermeasures of oil self-locking hydraulic cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the self-locking hydraulic cylinder will lead to premature wear of the piston seal, replace the piston seal; If the self-locking hydraulic cylinder is visibly scarred, the self-locking hydraulic cylinder must be replaced. It can be pressurized at one end of the self-locking hydraulic 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 self-locking hydraulic cylinder piston drift may not come from the self-locking hydraulic cylinder, the above method to determine the self-locking hydraulic cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.
The diameter of the cylinder is 180mm and the pressure is 14mpa. How many tons can the cylinder hold?
Calculate the area of the cylinder, 3.14*9*9=254.34 square centimeters, take the approximate number of engineering, 1 mpa pressure is about 10 kg per square centimeter, 14 mpa pressure is 140 kg per square centimeter, that is 254.34*140=35607.6 kilograms, it can be known that the cylinder can be about 35 tons in theory.
What factors does the movement speed of the cylinder in the hydraulic system depend on?
The hydraulic system should be the piston movement in the cylinder, and the speed should also be the speed of the piston, according to the piston speed formula: v=4qm/pai*(D^2-d^2) where q is the flow rate of the input hydraulic cylinder, m is the volumetric efficiency of the hydraulic cylinder, D, d is the diameter of the piston and piston rod, because other factors are determined, the movement speed of the cylinder depends on the flow rate.
