QinghaiSimple Mechanical devices controlled by cage movement should not be used to open or close the landing door.
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
Qinghai.Stop.
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: Each landing entrance should be equipped with a landing door,Qinghai2 meter micro electric lifting platform, which should cover the opening with its full width, it can automatically cut off the oil circuit and stop descent
In addition to ground protective fences,QinghaiMigao Electric Elevator, low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between 1m and 2m. And there should be at least protective railings, a half height middle crossbar and a toe board at least 150mm above the ground.
The setting of the cable guide frame should comply with the user manual and regulatory requirements.
The isolation and buffering rubber in various parts of the aluminum alloy electric elevator drive device are intact and tightly fitted.
Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
market.During normal operation, 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.
When the wall bracket adopts non matching standard products, design calculations should be carried out.
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.
Protective measures should comply with regulatory requirements.
Variable cost.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,QinghaiMicro electric elevator, and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.
The counterweight steel wire rope should be equipped with an anti loosening device that is sensitive and reliable.
The oil cylinder and sealing components are made of imported components to solve the problem of unstable oil pressure and oil leakage of components for customers.
Qinghai.Chain type electric lifting mechanism: With a good guiding mechanism, it can ensure that the equipment does not tilt during operation. Gear and rack electric lifting mechanism: precise transmission and high cost.
Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position, it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking, stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset, and installed in the machine room, the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position
