Speed limiter. To prevent the driving speed from exceeding the normal speed. A speedometer should be installed (not required for floors below or including the second floor), which is an individual mechanism that is integrated with a safety clamp; The entrance and exit of the passenger compartment should be equipped with safety doors. Public places,LimestoneElectric cargo elevator, family dormitories, and
Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.
Limestone.Savings, rate of increase and decrease. To ensure safe and reliable braking and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, it can cause the car to descend to the nearest floor position and open the door
During normal operation the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position
.Emergency manual valve: In case of power failure, the horizontal distance between the closed cage door and the closed landing door should not exceed 150mm. Otherwise, measures should be taken to make it meet the requirements, or side protection devices at the entrance of the landing station that meet the requirements should be equipped. The distance between any opening between the side protection device and the hanging cage or landing door should not exceed 150mm.
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.
Electric elevators used in various places.
The counterweight steel wire rope should be equipped with an anti loosening device that is sensitive and reliable.
Safety performance: Electric elevators not only have the safety device of traditional traction elevators, but also have an overflow valve to prevent excessive system pressure during upward movement
where.Civil engineering advantages: The pit depth of the guide rail type lifting platform is generally around 150-300mm, and the top layer is not affected. It can be customized according to the location and environment.
Setting requirements: The anti loosening and anti loosening parts between the connecting parts should comply with the provisions of the user manual and should not be replaced by other objects. For connecting bolts with pre tightening requirements, a torque wrench or special tool should be used to accurately tighten the bolts to the specified torque value according to the specified tightening sequence. When installing standard section connecting bolts, it is advisable to place the screw at the bottom and the nut at the top.
The quality of the standard section should comply with the product manual and specification requirements.
The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.
management.Horizontal lead screw mechanical electricity
The cargo is 0.5m.
Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
Limestone.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, and ensure that the lifting platform can be lifted to the rated lifting height.
Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient,LimestoneElectric curved arm elevator,LimestoneNiuli brand electric elevator, 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.
High lifting height, using side mounted oil cylinders, stable operation, noise free, easy maintenance, and longer service life.
