Water amusement equipment safety: daily inspection and maintenance methods for water slides
Water slides and water slides are common types of water recreation facilities. Visitors enter from the population, sit or lie, and the body has close contact with the surface of the slide. The surface of the slide is damaged or protruding, and the body of the passenger will Causes great damage. Therefore, the slides should be properly inspected and maintained frequently, which can ensure the safety of passengers and extend the service life of the slides.
Water slides are a common type of water play facilities. They are usually made of FRP material in a spiral or straight shape. Visitors enter from the population, sit or lie down, and slide down the smooth surface of the slide (with appropriate Water lubrication). Therefore, the slides should be properly inspected and maintained frequently, which can ensure the safety of passengers and extend the service life of the slides.
Inspection and maintenance work is generally carried out on the waterway of the slide, the support frame (column and steel frame), and electrical equipment.
First, the inspection and maintenance of waterways
1.1 Waterway inspection
For relatively smooth, slides where people can walk on the waterway, check each lane for the following items before using the equipment every day.
(I) Obstacle on the slide!
(2) Cracks, debris, and blistering on the surface of the slide
(3) Whether the joint is rough or broken
(4) Is the seal at the joint cracked?
(5) Is there any deformation at the turn?
(6)Whether the waterway is not shaking properly when walking on the waterway
(7) Whether the interface is loose.
For high-risk high-speed slides, personnel cannot pass through the waterway to check. This type of daily inspection is as follows:
(I) Observing the surface stains and breakage points from a distance
(2) Perform a test slip through the test slipper to observe whether the part or the entire structure is abnormally shaken!
(3) Let the test personnel record the place where the surface of the slideway is rented and the problems
When inspecting maintenance, the staff should use appropriate safety devices, such as fixing the rope to the slide, and climbing the entire waterway along the rope for inspection.
1.2 Waterway maintenance
Cleaning: When there is stain on the surface of the waterway, use a soft bristle brush and a neutral detergent to clean the dust, grease and sunscreen from the waterway. China Amusement Equipment ~ Information Network reminds you that the stains that cannot be cleaned can be polished and then repaired with a polish or wax.
Waxing: At least two high-quality waxes should be waxed twice a year. In general, before waxing, the spots and fading are fined with a good polish to the original gloss. Waxing prevents fading caused by long-term exposure to water in the UV. The more often the surface is waxed, the longer it lasts.
It is important to note that when using tools such as polishing, care must be taken not to overheat the surface. Polishing and overheating can cause fine sand-like particles on the surface of the waterway, causing blisters and streaks. This requires repainting.
Repair: Normal use can also cause debris and cracks in the FRP waterway. Repair must be done with a qualified glass glue.
In some places, there are fragments and cracks in the gel coat, or the scratch depth is greater than the thickness of the gel coat but the FRP surface is not completely broken. Follow the steps below to repair:
Tools to be repaired (l) sandpaper, 36-100 mesh, 220-320 mesh (mixed dry), 600 mesh (mild dry), (2) sanding tool! (3) acetone (4) masking tape (5) knife (6) Putty knife (7) Mixed wood board (8) Glass fiber resin hardener (9) Gel coat oil $ (10) Oil shaving (11) Slurry polisher (12) High quality wax.
(I) Sandy place is made of 36-100 mesh sandpaper and the rough edges are removed.
(2) Wash with acetone (required) and let it dry.
(3) Use two masking tapes for the area to be covered.
(4) Apply the repair mixture to the repaired area with a putty knife.
Note These places must be dry and clean, free of dirt such as dust and sand.
(5) Keep the repaired area dry and take 20 minutes to 1 hour to harden.
(6) After the area to be repaired is hardened, the area and the surrounding area are polished with 100 mesh sandpaper.
Note that sanding may move the masking tape. Paste it before painting.
(7) Apply a gel coat with a brush. Hardening takes 20-60 minutes.
Oil filler brushes and other T. must be cleaned with acetone.
(8) After the gel coat is dried, the tape is peeled off, polished with a polishing tool and 220-320 mesh wet sandpaper, and polished with a 600 mesh sandpaper.
(9) Wash the painted surface with a polisher and water.
Note: Repair tools include toxic, corrosive, flammable items that can only be used in extremely ventilated conditions. Avoid inhaling these gases as they may be injured. If you are indifferent to the human eye, rinse thoroughly with water for a minute and look for a doctor. If contact with skin or clothing, wash immediately with acetone.
Capillary cracks, sometimes referred to as spider webs or star-shaped cracks, may appear on the surface of gel coats or glass products. This is caused by the combined action of corrosion, shock and sway. Although it affects the appearance, it does not affect the structural strength. Capillary cracks can be repaired and can be re-coated with a 100-mesh sandpaper in the damaged area.
The edge of the sink includes a thick, hard gel coat. The pressure caused by normal use can also cause cracks in this place. These are not structural problems. To repair these edge cracks, you can use a 100 mesh sandpaper in the damaged area to re-coat a gel coat.
1.3 Inspection and maintenance of interface (connection part)
The slideway connection plays a very important role in passenger comfort and fun. The interface should be as flat as possible. It should be noted that the lower mouth cannot be larger than the upper mouth. The national standard is not required, and the height difference cannot be greater than 3 mm. A proper warranty will keep the connection smooth.
As the temperature changes, the FRP portion will deform. Therefore, the sealing of these parts is to use an elastic material. If these interfaces need to be resealed, all old fillers must be re-cleaned, the FRP is cleaned, and the interface refilled with a flexible polyurethane sealant. Do not use plastic that will harden. Sealing materials with excessive surface excess must be removed from the surface of the slide by a putty knife. Any remaining traces must be wiped off and the broken section removed with a thinner. Do not pour the thinner directly onto the sink connector as it will dissolve the sealant.
As used, the interface may become rough, especially if metal objects are slipping on the slide. For debris and cracks, follow the steps above for surface repair.
Second, the support frame inspection
Uncoated steel structures require inspections from time to time on a twice-yearly basis. Carefully inspect the area around the weld and galvanize if necessary. China Amusement. Equipment ~ Information Network reminds you if you are rusting, look for reasons and pay more attention. A comprehensive, professional inspection is required for a decade or more.
If a wooden structural frame is used, it is rarely used at present, and it is necessary to check its integrity, the firmness of the joint and others on an annual basis. After five years, one must conduct a comprehensive and professional inspection.
The environmental conditions of the locations where different equipment is used can vary greatly, affecting the above-mentioned 1 division time. In some corrosive environments, such as seaside or indoor installations, the spacing is usually shortened.
Inspection of other parts at least once a year
(1) Concrete stairs and tables, especially the leading edge of each level of the stairs, should be regularly checked for cracking, check whether the metal decorative F surface is aging.
(2) The weld should be inspected frequently and the bolts should be tightened.
(3) The riveted screws should be checked for consistency and corrosion, and the concrete floor next to the metal plate should be inspected for goodness.
Third, electrical / mechanical system inspection
Every day, it is necessary to check whether the wiring of the electric control cabinet and the motor is firm and there is no water ingress. It is normal to turn on the power before starting the device and check the voltage of the power supply. Check if the rotating parts of the motor, water pump, etc. are smooth and the lubrication is sufficient. The shelter of the pump population is also checked to ensure that there are no structural defects
Check whether the electrical protection on the electrical control cabinet is normal (such as the tidal current protection switch) and whether the electrical circuit is aging. Check that the ports of the water pump and water pipe are well sealed and that there is no looseness at the installation.
Every year, check whether the grounding protection of electrical equipment is complete and effective, and whether the grounding resistance meets the requirements of relevant standards. Whether the insulation performance of the motor, transformer, switch button and line of electrical equipment is good, and whether the insulation value meets the relevant standards.
Note: Whenever the mechanical system is inspected or repaired, including the shelter of the pump, all relevant equipment should be disconnected from the power supply and the locking procedure should be used.
The above is the general inspection and maintenance, the user must strictly follow the instructions provided by the manufacturer to use and check the maintenance manual. In particular, some special materials and processes are used in the manufacture, and there may be additional requirements during maintenance. The use of water amusement facilities is relatively seasonal. When not in use, the equipment should be thoroughly cleaned and stored. When used, the equipment should be properly inspected and maintained to ensure the safe use of the equipment.
