Fengnan3 meterThe spacing between wall brackets and the height of guide rails above the high attachment point should comply with the requirements of the user manual.
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.
Fengnan.Setting requirements: Construction electric elevators should be equipped with up travel (limit) switches.
Emergency manual valve: In case of power failure, it can cause the car to descend to the nearest floor position and open the door
.Before installation, the installation unit should confirm that the foundation, foundation bearing capacity, embedded parts, and foundation drainage measures of the installed construction electric elevator and auxiliary heavy equipment comply with the requirements of the special construction plan for the installation and dismantling of the construction electric elevator based on the construction electric elevator foundation acceptance form, concealed engineering acceptance form, and concrete strength report.
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.
Horizontal lead screw mechanical electricity
The scaffolding of the parking platform should be laid tightly and firmly.
The cleanliness of the hydraulic station is an important aspect of the electric elevator hydraulic station, so it should not be taken lightly. And from a professional perspective, there are relevant rules and requirements that should be referred to in the specification manual,FengnanTen meter electric elevator, so as to have a correct understanding and know how to achieve good cleanliness.
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, 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.
Statistics.The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve,FengnanElectric boom elevator, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, resulting in a safety clamp. To prevent breakage of the lifting wire rope. A safety clamp that can simultaneously cut off the power supply and stop the car from falling should be removed from the car. A car without safety tongs is not allowed to ride or carry people. If it is a simple electric elevator, there should be a safety device (such as a safety stop pin) to prevent people from suddenly falling when loading and unloading goods in the car; Electric elevators with three or more floors (including three floors) for passengers or passengers.
Use floor doors and cage door devices on construction sites where conditions permit.
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.
plan.Principle of electric elevator rotary valve: When the electric elevator rises the rotary valve will automatically open. To close the plug valve, it is necessary to first turn the handle to turn the plug to a 90 degree position until it is closed and then turn the transmission handwheel to lower the plug and achieve sealing.
The impact load can cause early wear, fracture, and fragmentation of mechanical structural components, as well as generate impact pressure in the hydraulic system, which in turn can damage hydraulic components, oil seals, and high-pressure oil
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.
Fengnan.The pump body adopts an integrated pump station, which can also be selected according to customer requirements to meet customer ideal requirements.
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.
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
