a hydraulic control one-way valve
To ensure safe and reliable braking of the lifting platform and prevent accidents, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure. Electrical system explosion-proof button SB1&flash; The rotation of the SB6 motor and the commutation of the explosion-proof electromagnetic directional valve are used to maintain load increase or decrease, and; Program adjustment time delay to avoid frequent movement of electric elevators that may affect their service life.
Drainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).
Xilingol League.Setting requirements: Construction electric elevators should be equipped with a down travel (limit) switch. The down travel (limit) switch should be able to automatically stop the cage running at rated speed before reaching the lower limit switch.
Manual pump: When the system malfunctions, the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position
.Operating cost advantage and low failure rate: Due to the use of advanced hydraulic systems and good methods, occupying a relatively small area,Xilingol LeagueFlagpole electric elevator, improving the utilization rate of the wellbore area.
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,Xilingol LeagueTatami electric elevator, the door should be able to withstand and have no deformation; - Deformation not exceeding 30mm; After the test, it worked normally.
When a rigid 5000mm2 square or circular flat surface is applied with a normal force of 600N to either side of the door, the door may not meet the above requirements, but safety should be maintained.
Folding arm electric elevators are mostly driven by hydraulic means, and the source of power for the hydraulic system is hydraulic oil. Only when the hydraulic oil quantity is sufficient and the oil quality is high, can the folding arm electric elevator provide greater torque output, thereby improving work efficiency. So, how can we determine whether the newly added hydraulic oil quantity is sufficient? What is the hydraulic oil quantity standard?
Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
Click to view.Steel wire ropes, pulleys, wear, deformation and corrosion of steel wire ropes
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,Xilingol LeagueSmall electric elevator, deformation, and corrosion of steel wire ropes
The entrance of each landing platform must be equipped with a landing door, which must open towards the landing platform side, and the door bolt must be set on the side next to the construction electric elevator.
Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descent
Click to view.Acceptance: Concrete strength grade C30, strength testing report.
The device should be used within the valid calibration period and operate effectively and reliably. The anti fall safety device should have a valid inspection certificate (or inspection report), and the validity period should not exceed 1 year. Anti fall safety devices have been manufactured for five years
The counterweight guide rail should meet the specification requirements.
Xilingol League.Setting requirements: Each landing entrance should be equipped with a landing door, which should cover the opening with its full width, and should not open towards the lifting passage.
The setting of the cable guide frame should comply with the user manual and regulatory requirements.
When the landing door is closed, the full width of the lifting passage opening should be covered.
