stay Design of hydraulic station The primary color of the hydraulic cylinder is simple and easy to operate. After the drilling rig is processed, all the original data of the hydraulic cylinder are subject to strong heat treatment punishment. The grinder has special specifications, which can be customized and easy to carry, so that the hydraulic cylinder can continue to work and is not easy to wear and tear. Surface baking paint treatment, should adhere to a certain degree of parallelism and perpendicularity. Otherwise, the cylinder will be directly loaded by the trunnion as the support point. The pin hole and ear pin hole (or trunnion) of the piston rod end should be left to the hand, and the support should be set between the cylinder block and the piston rod. The road is larger to prevent the self weight from going down.

The decomposition of emulsions, hoses or other broken parts can cause dirt, and some internal components, such as metal fragments, abuse or use of incompatible materials, can diffuse from liquid additives, hydrolysis and oxygen, resulting in chemical corrosion, such as gas debris. Small pieces of metal will be embedded in the seal, and foreign matter in the system is another major component of the hydraulic sealing effect. A good solution is to simply install the dust catcher or dust shield. The main reason for chemical waste of hydraulic cylinder seal is inaccurate material selection, which often occurs when the raw material of hydraulic seal is chemically loose. Therefore, it is necessary to pay attention to cylinder and cylinder inner surface scratch, excessive wear, seal leakage, etc. Dust or Hydraulic system Medium decomposition. The discoloration of soil and seals is also one of the signs of chemical erosion. The hydraulic seal interface may be damaged by chemical corrosion, which usually consists of some external components. In the process of column falling, many external foreign matters will enter the machine system. The sealing ring of the oil cylinder should not be installed too tightly, especially the U-shaped sealing group will increase the flow resistance of the piston rod.

If it is too tight, there are different decisions. The working meaning of pressure cylinder and hydraulic cylinder is generally the same, but their working principles are the same. First, the application of cylinder is liquid. Hydraulic cylinder piston cylinder and cylinder plug, mainly from the necessity of design and convenience of work, the current application of hydraulic cylinder, also has the same widely used cylinder is pressure cylinder, its application field is also very wide. It also lost a large customer base and used an ultra wide cylinder. And the force transmitted is much greater than that of a pneumatic cylinder. The material of hydraulic cylinder is the same as ordinary medium carbon steel, Hydraulic station The plunger cylinder of the hydraulic cylinder can only supply oil for one target and work under bias pressure. During operation, the piston cylinder can supply oil at both ends of the piston. Identification: the structure of piston cylinder is composed of piston and rod body. Since the atmospheric capital is used for continuation and no consumption is collected, the pressure test of pressure vessel can be carried out directly, and the plunger with high rated rod stiffness may not be selected. It can work in both directions. The equipment can be used for lifting, bending, straightening, extrusion, welding, lifting, stretching, dismantling, stamping, construction reinforcement, bridge, construction machinery, etc. The plunger is not a piston, and the front rod is just a bar. Similarly, with regard to the occurrence of pressure, the hydraulic pressure of piston with limited pressure is developed into six rods, but it is specially developed according to atmospheric pressure. It is used for general purpose of piston. At present, the performance of the hydraulic cylinder is very good, but because of the convenience of use, and the hydraulic cylinder of the hydraulic cylinder is not only a few. For the cost of this point, the plug should be considered for the pressure cylinder compared with the hydraulic cylinder, the burr at the corner and root, and the burr of the large cylinder diameter, or the sealing piston is easy to wear and wind resistance.
