CaenSmall elecThe end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.
After the electric elevator passes the inspection, the user unit shall organize the leasing unit installation unit, the acceptance shall be organized by the construction general contracting unit. The acceptance form should be signed by the relevant responsible person.
Caen.High altitude operations and maintenance in areas such as repair and supervision unit to conduct acceptance. For the implementation of construction general contracting,CaenLarge electric elevator, logistics, electricity, transportation, petroleum, hotel, sports center, mining, and enterprise. The lifting system of the lifting platform is driven by hydraulic pressure, also known as hydraulic lifting
Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
.Setting requirements: The foundation and foundation of the construction electric elevator should meet the requirements of the user manual. Before installing the construction electric elevator, the foundation should be inspected and accepted according to the requirements of the specifications. Only after passing the inspection can the installation be carried out.
The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.
Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient, and the valve can be opened and closed at any time; The installation of a rotary valve reduces the friction of the sealing components; Compact structure, small size, and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.
The counterweight guide rail should meet the specification requirements.
The cleanliness of the hydraulic station is an important aspect of the electric elevator hydraulic station, so it should not be taken lightly. And from a professional perspective, there are relevant rules and requirements that should be referred to in the specification manual, so as to have a correct understanding and know how to achieve good cleanliness.
Secondly, for the replacement of hydraulic oil on the lifting platform, it is recommended to replace it every three months. If the frequency of use is not high, it can be replaced once a year. The hydraulic oil must be clean, and after changing the hydraulic oil, it must be automatically lifted and lowered 2 to 3 times to ensure that the air in the oil cylinder is completely discharged, maintain sufficient space, and ensure that the lifting platform can be lifted to the rated lifting height.
How much is it.The safety distance between the outer edge of the upper part of the landing door and the moving parts of the electric elevator during normal operation should not be less than 0.75m; If the rated speed is not greater than 0.7m/s, the safety distance can be 0.40m.
The motor of the hydraulic guide rail lifting platform is set around the wellbore, occupying a relatively small area, improving the utilization rate of the wellbore area.
Steel wire ropes, pulleys, and counterweight steel wire ropes shall comply with the following regulations: the characteristics of steel wire ropes shall comply with the requirements of General Purpose Steel Wire Ropes GB/T20118; Maintenance, wear, deformation, and corrosion of steel wire ropes
The verticality of the guide rail frame should meet the requirements of the specifications.
Quality Assurance.Once again, weekly inspections should be conducted to check whether the connecting screws at various parts of the lifting platform are tightened, whether there is a lack of hydraulic oil, scissors, wiring and oil cylinder once a week to avoid dust and debris affecting normal operation.
Construction electric elevators should be equipped with travel limit switches, as follows: automatic reset type upper and lower limit switches should be installed on construction electric elevators, but the upper and lower limit switches should not be triggered as high
Setting requirements: Drainage measures should be set up for the foundation of construction electric elevators to ensure smooth drainage.
Caen.The counterweight guide rail should meet the specification requirements.
When applying a normal force of 300N to any position on either side of the door using a rigid 5000mm2 square or circular flat surface in the locked position of the landing door,CaenElectric elevator mobile type, the door should be able to withstand and have no deformation; - Deformation not exceeding 30mm; After the test, it worked normally.
Installation verticality deviation guide rail frame erection height, h/mH≤ 7070100150H& gt; 200 verticality deviation/mm≤ (1/100h≤ 70≤ 90≤ 110≤ 130 pairs of steel wire rope construction electric elevators, the verticality deviation of the guide rail frame should not exceed (5/1000) h.
