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.From the above comparison, it can be seen that hydraulic electric lifting mechanisms have stable lifting, long service life, large load bearing capacity, and are relatively simple,High altitude operations and maintenance in areas such as repair, logistics, electricity, petroleum,ZhangjiakouBelo Horizonte, chemical hotel, sports center, mining, and enterprise. The lifting system of the lifting platform is driven by hydraulic pressure, also known as hydraulic liftingElectric elevators used in various places.FomentoWhen applying a normal force of N to any position on either side of the door using a rigid mm 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 mm; After the test, it worked normally.The landing door should be in a normally closed state. Without the permission of the construction electric elevator driver, the landing door shall not be opened.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.

Once again, weekly inspections should be conducted to check whether the connecting screws at various parts of the lifting platform are tightened, whether the sealing rings are damaged or ineffective, whether there is a lack of hydraulic oil, and whether the oil cylinder is leaking. It is necessary to clean the lifting frame, scissors, wiring, and oil cylinder once a week to avoid dust and debris affecting normal operation.Only after the operation of professional personnel can the suspension cage movement be restored.When the distance between the outer edge of the construction electric elevator and the edge line of the external overhead power line cannot meet the requirements in the table above, effective protective measures should be taken.Interpretation and observation,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 - millimeters higher than the bottom of the box. If the hydraulic oil becomes dark, sticky,ZhangjiakouEnshad, or has foreign objects such as gravel,ZhangjiakouBielefeld, it should be replaced in a timely manner ( # 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, tighten the joint, remove the oil filter, clean it with compressed air, and then return it to the oil tank and connect the pipeline.Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination, shallow foundation pit required, large stroke, 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.To meet the needs of choreographers and choreographers in different plays, different heights of the lifting platform can be used to change the shape of the stage according to the requirements of the choreographers and choreographers, in order to adapt to the requirements of the plot for the scenery or venue, and save manpower and material resources for setting up. By using the tilting device of the lifting platform to form a tilted platform, a better highlighting effect can be achieved in various performances. According to the needs of the plot, special atmosphere and effects can be created. Even simple stage machinery often participates in performance activities, creating unexpected atmosphere and effects according to the needs of the plot. For example, using the low-speed descent of the lifting platform to represent a sunken ship in the sea, using the valves on the lifting platform and the sudden disappearance and appearance of actors on the lifting platform.

Many theaters use a lifting platform as a vertical transportation tool for goods. The rear of the main stage or the end of the side stage in many theaters are equipped with a set container transportation lifting platform, which is used to vertically transport items from the ground to a designated location or even the stage plane. The lifting platform of the music pool is often used for transporting movable seats, etc.market priceAcceptance: Concrete strength grade C, strength testing report.The coaxiality between the motor shaft and the worm shaft in the aluminum alloy electric elevator drive device should be less than .mm, and there should be a mm gap at the shaft end to ensure that the motor bearings bear reasonable loads and reduce motor operating noise; electricSetting 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.Zhangjiakou,Setting requirements: The landing door should be standardized and tooled.When the landing door is closed, the full width of the lifting passage opening should be covered.The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator
