| Hydraulic three-way machine on the hydraulic cylinder common problems
L Hydraulic cylinder creeping.There are two main reasons: one is the cylinder that has just been repaired or the cylinder that is placed for a long time. When it is used, it appears to be creeping. Sometimes, it can also see the foam hydraulic oil overflow in the hydraulic tank, which is because the air is mixed with the system and the air can be cleaned.Second, the mechanical resistance is too large, it is necessary to dismantle the cylinder, live cold and piston rod.
The thrust of the cylinder is lack, and the cylinder does not move when there is load.Can do the following experiments: in the empty load of the cylinder to operate the reversing valve, if the cylinder can be elastic from the mountain, and sometimes the speed of the extension and retraction is faster than normal, it can be determined that the cylinder is wrong.The oil seal and support ring on the piston are severely damaged due to the impurities or iron chips entering the cylinder, so that the rod cavity and the rodless cavity of the cylinder are connected, forming a differential circuit.
3. Oil leakage. In addition to the external oil leakage caused by the damage of connecting oil pipe and oil pipe O-ring, the internal oil leakage caused by the sealing failure of piston rod on the cylinder head is also a common problem.
4 pull cylinder, hydraulic cylinder pull cylinder is mainly because the wear ring between the piston and the cylinder is too worn to make the piston and cylinder directly touch, the piston hardness is greater than the cylinder hardness, the piston will cut the cylinder and lead to the cylinder.After the cylinder is pulled, the hydraulic cylinder is raised and lowered weakly. If the cylinder is pulled seriously, the cylinder becomes invalid.
5 deformation, deformation of the hydraulic cylinder is mainly due to the impact of external force or overload of the hydraulic cylinder.
6 hydraulic cylinder piston rod is damaged, such as the piston rod is scratched or the piston rod surface is connected with the hollow cavity.
When customers order three-way machine equipment, the three-way equipment is mainly capable of producing three-way pipe fittings. The three-way machine mainly has the same diameter and reducing diameter three-way, and the shape of the three-way is divided into T shape and Y shape.Tee machine main production of three materials have carbon steel, alloy steel stainless steel and so on.
The main power of the three-way machine is hydraulic cylinder. The body of the three-way machine is a non-standard product, so there is no specific specification and model. We can directly customize it according to the specific requirements provided by customers.
First of all, the three-way machine is the most advanced mechanical equipment for the production of three-way.Tee machine leading process through water pressure to squeeze straight pipe into three, reduce lead filling, repair lead blank drilling, lead back and other processes, to save costs and production time, in order to ensure the stability of water pressure, we use pressure balance to stabilize the water pressure in the copper pipe squeeze three, is the copper pipe in the extrusion process to maintain a constant pressure.
The company is mainly the production of the most professional three-way machine manufacturers, professional production and manufacturing of various mechanical equipment.
