How to maintain three-way oil cylinder?

The three-way cylinder can reduce the problem of the cylinder through a process, there are two main reasons: first, the cylinder that has just been repaired or the cylinder that has been placed for a long time begins to crawl, and sometimes you can see the foamy hydraulic oil overflow in the hydraulic tank, because the air is mixed in the system, the air can be removed. Second, the mechanical resistance is too large, it is necessary to disassemble the cylinder, live cold and piston rod. Insufficient cylinder thrust, cylinder does not move when there is a load. The following experiments can be done: Operate the reversing valve when the cylinder is unloaded. If the cylinder can be elastic from the mountain, sometimes the expansion speed is faster than normal, it can be concluded that the cylinder is faulty. The oil seal and support ring on the piston are seriously damaged by impurities or iron filings entering the cylinder, so that the rod cavity of the cylinder is connected with the rodless cavity to form a differential loop. Oil leakage, hydraulic cylinder external oil leakage due to damage to the connecting tubing and tubing O-ring, is also a common problem of cylinder head piston rod seal failure resulting in internal oil leakage. Pulling cylinder, hydraulic cylinder pulling cylinder is mainly the wear ring between the piston and the cylinder after excessive wear directly contact the piston and the cylinder. The piston hardness is greater than the cylinder hardness, and the piston will cut the cylinder, causing the cylinder to stretch. After pulling the cylinder, the hydraulic cylinder is unable to lift, the pulling cylinder is serious, and the cylinder is invalid. Hydraulic cylinder deformation is mainly due to the impact of external force or overload of hydraulic cylinder. The cylinder piston rod is damaged, such as the piston rod is scratched by a foreign object or the piston rod is connected to the hollow chamber.

The operation process of the tee machine: put the tube embryo into the mold. The slider drives the upper and lower die, and finally closes and releases the die. The two plungers move forward to flush water into the tube embryo, the two side cylinders continue to move forward synchronously, squeeze the tube, and the supercharger will enter the high-pressure liquid (such as water) into the tube embryo. At this time, the pressure of the hydraulic press can reach the pressure that can be achieved. At the same time, the tube embryo was extruded and expanded. If according to customer requirements, a lower top cylinder can be made to support pipe fittings and top materials, and then rise and fall. If the pressure exceeds the pressure, the hydraulic pressure will automatically release the pressure within a certain period of time. The extrusion process is to expand in three or more directions to improve the pressure medium.

The main requirements of the working medium of the tee machine are: the use of pressure medium as white emulsified water, the flow and heat dispersion are fast, and the transmission efficiency of the medium is provided. After rising, its water can be used back and forth, and it can work for a long time without changing its quality. It can prevent corrosion and pollution. Easy to seal. Good lubrication performance during ascent. Water expander takes water as the working medium, adding emulsifying powder in ordinary water to become an emulsion, and using water to reduce losses in the working process. In this case, the lubricity and corrosion resistance of the emulsified water are closer to that of the oil medium liquid. And it's not easy to burn, and it's pretty cheap.

The tee machine is mostly a simple mechanical mechanism, which can not accurately judge the size and position of the blank to be extruded, and can not control the extrusion size, resulting in insufficient tee molding size and accuracy, affecting its performance. Tee machine The tee machine produced is pipe fittings and pipe fittings. The pipe fittings produced by the tee machine are also called the pipe fittings tee or tee pipe fittings, and the stainless steel equal diameter tee tee joint is used in the branch pipes and tee processing of the main pipe. The blank is usually extruded by cold extrusion.

Three-way machine is a machine that produces three-way machines, also known as equipment. Tee machine mainly produces carbon steel, stainless steel, alloy steel and other tee machine. Tee machine is mainly used for pipeline connection, and the tee machine is divided into equal diameter and reducing diameter tee machine. The model and mold of the tee machine are customized according to the needs of customers. The material of the three-way machine is divided into carbon steel, stainless steel, alloy steel, etc. Tee machine through the mold extrusion molding. Three-way machine is an integral frame structure, with strong rigidity, stable and reliable in the operation process. Tee machine equipment has an independent power mechanism and electrical system, using PLC button control of their own system, m3 diameter.
