(Germany roller press hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）
roller press hydraulic cylinder are widely used in Germany，because of long service life，smooth movement，high work efficiency.So our company has designed roller press hydraulic cylinder for customers from Germany.
roller press hydraulic cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the roller press hydraulic cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the roller press hydraulic cylinder. c. The roller press hydraulic cylinder seal is extruded, if the O-ring is obviously extruded at the roller press hydraulic cylinder seal, replace the roller press hydraulic cylinder seal.
The scar on the sliding surface of the roller press 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 roller press hydraulic cylinder wall. Therefore, before installation, these scars must be fully repaired.
The repair method of the roller press hydraulic cylinder: the repair of the roller press hydraulic 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.
If the piston rod and roller press hydraulic cylinder are stuck or the roller press hydraulic cylinder is blocked, at this time, no matter how to operate, the roller press hydraulic cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the roller press hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.
What is a differential cylinder?
The differential cylinder is by connecting the return oil of the rod cavity through the pipeline, allowing them to flow into the rodless cavity, thereby speeding up the extension speed of the piston rod. In fact, the cylinder is still the cylinder, but the oil circuit is related to the connection. The oil connection mode in which both chambers of a single rod hydraulic cylinder are fed hydraulic oil is called differential connection.
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.
