San FranciscoE
San FranciscoEEvery theater is a public place with a large number of people, in order to prevent accidents caused by the crushing of electric elevators or improper control by drivers. Electric elevators should be equipped with the following necessary safety devices to ensure that the car of the electric elevator stops rising or falling in a timely manner.
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.
San Francisco.Platform.
Mechanical devices controlled by cage movement should not be used to open or close the landing door.
.Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.
The L distance depends on the selected wall mount model.
When the wall bracket cannot meet the requirements of the construction site, it should be designed and calculated separately.
Acceptance: Concrete strength grade C30, strength testing report.
Construction electric elevators should be equipped with upper limit switches that are sensitive and reliable.
During loading and unloading, the horizontal distance between the edge of the cage door and the edge of the landing station should not exceed 50mm.
How much does it cost?.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
Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination, shallow foundation pit required, stable operation, low noise, accurate positioning, and low cost. Adopting a horizontal screw drive and a scissor fork structure to achieve the lifting motion of the table, it can be stopped arbitrarily within the range of travel.
Tank oil temperature protection: When the oil temperature in the tank exceeds the standard setting value, the oil temperature protection device sends a signal to suspend the use of the elevator. The elevator can only be started when the oil temperature drops
Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.
Credit guarantee.The full height landing door should meet the following requirements: the net height of the landing door opening should not be less than 0m. In special circumstances, when the net height of the building entrance is less than 0m, it is allowed to lower the height of the lower door opening,San FranciscoDecoration electric elevator,San FranciscoElectric automatic elevator, but in any case, the net height of the lower door opening is not less than 8m. (Article 1 of GB26557-2011)
Correct use can also greatly improve work efficiency. So how should it be used?
The spacing between wall brackets and the height of guide rails above the high attachment point should comply with the requirements of the user manual.
San Francisco.The setting of the cable guide frame should comply with the user manual and regulatory requirements.
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.
Monthly maintenance and inspection of hydraulic lifting platform rollers, intermediate shafts and bearings, oil cylinder pin shafts and bearings, boom hinge shafts and bearings for wear. Add some oil to each part to extend the service life of the lifting platform bearings. The quality and level of hydraulic oil. The lifting platform should be raised throughout the entire process, and at this position, the hydraulic ground should be 40-50 millimeters higher than the bottom of the box. If the hydraulic oil becomes dark, sticky or has foreign objects such as gravel, it should be replaced in a timely manner (32 # hydraulic oil). Annual maintenance and inspection of all hydraulic pipelines and joints of the lifting platform. The pipeline must not be damaged,San FranciscoSmall and simple electric elevator, and the joints must not be loose. All joints must be tightened. Remove and disassemble the lowering valve of the lifting platform, blow out the plunger with compressed air, then install it and reinstall it. Drain and discard the hydraulic oil, tighten the joint, remove the oil filter, clean it with compressed air, and then return it to the oil tank and connect the pipeline.
