neutralInstallation of electric elevators for fire protectionWhat are the steps for how to operate correctly

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.

Setting requirements: Before starting work every day and changing shifts the driver of the construction electric elevator should inspect the construction electric elevator according to the requirements of the user manual and specifications,neutralElectric single arm elevator, record the inspection results, and report any problems found to the user unit.

neutral.The magnetic directional valve returns to the fuel tank. To ensure stable landing of heavy objects and safe and reliable braking,neutralFolding electric elevator, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the landing speed does not change due to heavy objects. It is adjusted by the saving valve

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

.Setting requirements: Before starting work every day and changing shifts, the driver of the construction electric elevator should inspect the construction electric elevator according to the requirements of the user manual and specifications, record the inspection results, and report any problems found to the user unit.

The safety notice board for construction electric elevators should be prominently placed on the hanging cage for the rated load capacity and rated number of passengers of the construction electric elevator. It is strictly prohibited to use construction electric elevators beyond the rated load capacity or rated number of passengers.

Small safe operation distance: Circuit voltage (kV) of external power lines<11~1035~110220330~550 Small safe operation distance (m) 4681015 Setting requirements: A small safe distance should be maintained between the outer edge of the construction electric elevator and the edge of the external overhead power line.

Emergency manual valve: In case of power failure, it can cause the car to descend to the nearest floor position and open the door

Try to use this equipment in areas with wind force less than level five, and avoid using it when the wind force is too strong to avoid accidents.

Setting requirements: The spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.

Production department.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, 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, remove the oil filter, clean it with compressed air, and then return it to the oil tank and connect the pipeline.

The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator, with a size of 8 meters by 2 meters.

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, the door should be able to withstand and have no deformation; - Deformation not exceeding 30mm; After the test, it worked normally.

The foundation base or embedded parts should be fully embedded in the concrete foundation plate.

Honest service.When the wall bracket adopts non matching standard products, design calculations should be carried out.

The movement of its related components is direct.

Setting requirements: When the distance between the outer edge of the construction electric elevator and the external overhead power line cannot meet the requirements of a small safety distance, the protective measures taken should comply with the specification requirements.

neutral.There is no need to set up a computer room above the shaft like an elevator, and the top floor height can be installed at least 2.5 meters.

Then, the lifting platform platform platform that carries the load needs to be balanced,neutral200 kg electric elevator, and no deviation of one side is allowed. The lifting of goods does not allow people to stand on both sides of the platform, and the lifting of goods should try to maintain a stable and uniform speed.

According to the needs of different performance genres, the form of the stage can be changed. For example, an extended stage using a lift can make the theater have various forms such as an end stage, an island stage, a T-shaped stage, or a hall.
