What should be done when hydraulically driven amusement equipment needs maintenance

Many amusement devices use hydraulic transmission systems such as automatic aircraft, our common octopus, brave turntables, dual flight, head-flying chairs and so on. At present, the manufacturing capacity of hydraulic components in China is limited, and the gap between quality and foreign countries is large. In order to save costs, the manufacturers of entertainment equipment only pay attention to Kang's price ratio, resulting in leakage of amusement equipment during a period of time. Three leakage currents (leakage current, leakage current, and leakage phenomenon are the current disadvantages, mainly due to the leakage of component gaps caused by the pressure difference between the oil flow in the hydraulic components and the pipeline, and the leakage in the hydraulic system is serious, which will lead to insufficient system pressure. Affecting the safety of equipment can also cause the machine appearance of the machine capacity, environmental pollution, and increase the operating cost of the amusement equipment.Therefore, it is necessary to control the leakage of the hydraulic system.
Leakage amusement equipment of the hydraulic system mainly fixes two leaks of seal leakage and sealing movement. Fixed seal leakage includes the main part of the bottom of the cylinder, fittings, etc. The seals include the movement of the piston rod and valve stem of the cylinder. Oil leakage can be divided into external leakage and internal leakage. External leakage is leakage from the system to the environment, the main hydraulic oil, the internal leakage is due to the presence of pressure difference between the seal and the failure of the high pressure side, hydraulic oil in the system from the high pressure side of the flow The low pressure side.
There are several reasons:
(1)
Design factors choose seals. The reliability of the hydraulic system depends on the design of the hydraulic system to seal and seal the choice. If the design of the seal structure is reasonable, the choice of seals does not meet the standards, and the type of hydraulic oil and seal material compatible, load, limit load and speed are not taken into account in the design. All of this will be caused, directly or indirectly, by leaks in the hydraulic system to varying degrees. In addition, because the game device is the most outdoor, using the environment with dust and impurities, so design a suitable dust seal to prevent dust and Other dirt from entering the system to break the seal, oil contamination and leakage.
Hydraulic shock and vibration. Hydraulic shocks and vibrations caused by loose fittings can cause leakage. This is often encountered with amusement device malfunctions.
(2)
Manufacturing and Assembly Factors Manufacturing Factors. All hydraulic components and seals have strict dimensional tolerances, surface treatments, surface roughness and shape tolerances. During the manufacturing process, such as a piston with a cylindrical radius, the depth or width of a seal groove, the seal ring is arranged at an ultra-poor aperture, or the problem of roundness due to machining, burrs or pits, chromium When closed, the seal will have deformation, scratches, crushed or no pressure seal function loss. In order for congenital leaks, the parts themselves will leak during assembly or use.
Assembly factor. Parts of the trade were carefully reviewed before assembling the hydraulic components, the assembly should be part of a little oil, light pressure immersion, clean diesel, especially rubber seals, dust-proof sarcasm, o application - ring components, if gasoline will make it Easy aging loses its original elasticity and loses its sealing performance. The General Assembly should put an end to brutal operations, especially copper rods and ramming cylinders, sealing flanges, etc. Excessive force may deform the parts.
(3) Dynamic seal wear and damage Pneumatic seals are generally made of oil-resistant rubber material, which can cause cracks to occur if they are used for a long period of time. Abrasives, dust, impurities in the oil, movement of the dynamic seal, and a long time will also accelerate the aging and damage of the sealing member. If the parts in the process of collision and damage, but also scratches the seal, most likely to cause internal leakage of the cylinder.
(4) Impact on the environment

Mini shuttle

In the hydraulic system where the hydraulic cylinder is used as the main component of the entertainment equipment, the piston rod is directly exposed to the environment and the work process is exposed. Although the guide sleeve is provided with a dust-proof ring and a seal, it also inevitably brings dust, dirt, and hydraulic pressure. The system accelerates scratches and wear on seals and piston rods, causing leakage. Humidity in the working environment may cause water to enter the hydraulic system, water will react with the hydraulic oil, and the formation of acidic substances and sludge will reduce the lubrication performance of the hydraulic oil and accelerate the wear of the parts. Water will also cause the valve stem to engage the control valve, causing the control valve to control the difficulty of scraping the seal, resulting in a leak. The service life of the seal will be halved at every 10 degrees, so the best oil temperature should be less than 60 degrees Celsius, or the seal is premature. Under high pressure, the hydraulic oil can be about 10% of each dissolved air, under the pressure of the hydraulic system, the oil will dissolve more air, the air in the oil forms bubbles, and if the hydraulic working process time pressure high pressure and low pressure quickly During a short time between transitions, it will cause the high temperature side of the bubble to be on the low voltage side of the burst. At this point, if the components of the hydraulic system have pits and breaks, the hydraulic oil will rush on the surface of the assembly to accelerate wear and cause leakage.

Leakage control in the prevention and hydraulic system is in design and machining links to ensure the geometric accuracy of each component, the correct choice of seals, reduced shock shock and absorption by the damper holder, use of storage devices where possible, proper pressure control Valves to protect the components of the system, install fittings, and replace the pipes with oil return blocks; the second is to select the correct assembly and maintenance methods and found that the timely treatment of damage, especially the piston rod, cylinder damage hydraulic The components most easily affect the seal. Use special tools in the seal assembly as much as possible, and apply a little grease on the seal ring; third is to control the contamination in the hydraulic system to take regular test oil, filter device and a tank cleaning source of the working environment, cut off the hydraulic external factors (water , dust particles, etc.) Contaminated components. In order to prevent the temperature from being too high, forced cooling devices and the like may be provided. In short, the leakage of machinery and equipment hydraulic system is a multi-faceted factor. It should be considered and reasonable and effective measures should be taken to minimize leakage.
