| The composition and function of the three-way machine are briefly introduced
The three-way machine is mainly composed of oil pump, motor, PLC control box, water tank and corresponding model molds.
The body of the three-way machine is a non-standard product, so there is no specific specification and model. We can customize it according to customers' requirements.The diameter of the tee is 21mm-630mm and the wall thickness is 3mm-20mm.
Tee machine mainly produces carbon steel, stainless steel pipe made of three special pipe fitting machinery, pipe using liquid stretch molding, the largest molding specifications of 426, three machine in pressing products with high synchronization performance, easy operation and other characteristics.The three-way machine is equipped with super high pressure relief valve and supercharger, which can meet all requirements of customers.The three-way machine is mainly equipped with an independent control cabinet, and the operation button of the three-way machine is suspended on the fuselage.The above briefly introduces the composition and function of the three-way machine.The company is based on good faith, quality first, customer first, common development of the purpose of the enterprise, realistic and innovative business philosophy.The majority of users have been recognized.Get the trust of customers.Three - way machine in the production process of the hydraulic cylinder will appear several common problems
There are two main reasons for the hydraulic cylinder of the three-way machine: one is the cylinder that has just been repaired or the cylinder that has been placed for a long time. When it is used, it appears to be creeping. Sometimes, it can also see the foam-like hydraulic oil overflow in the hydraulic tank.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.
7. Our company briefly introduced several common faults of the hydraulic cylinder in the production process of the three-way machine.Hope each customer in the operation of the three - way machine will pay attention to the above introduction.
