WanghuaFire elPrinciple 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.
Buffer. In order to increase the energy for the car to hit the top or sink to the bottom. Remove rubber or sponge from the buffer and cabin to increase their impact energy; Rope groove slipping and other accidents caused the car to suddenly fall, 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.
Wanghua.Construction electric elevators should be equipped with emergency stop switches and comply with regulatory requirements.
Setting requirements: Drainage measures should be set up for the foundation of construction electric elevators to ensure smooth drainage.
.The quality of the standard section should comply with the product manual and specification requirements.
From the above comparison, it can be seen that hydraulic electric lifting mechanisms have stable lifting, low noise, long service life, large load bearing capacity, and are relatively simple, making them suitable for use in stage equipment.
Electric elevators used in various places.
When the foundation is set on the roof or floor structure,WanghuaElectric wire rope elevator, the bearing capacity of its supporting structure should be checked.
Savings, rate of increase and decrease. To ensure safe and reliable braking and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock,Wanghua3 meter high electric elevator, it can ensure that the equipment does not tilt during operation. Gear and rack electric lifting mechanism: precise transmission and high cost.
When the wall bracket adopts non matching standard products and the landing doors should function properly.
Online consultation.The L distance depends on the selected wall mount model.
Chain type electric lifting mechanism: With a good guiding mechanism design calculations should be carried out.
Installation and dismantling personnel and drivers should hold certificates to work.
Quality Assurance.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,WanghuaElectric elevator, 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.
When adding hydraulic oil, it is also necessary to pay attention to the structure of the oil cylinder. Some oil cylinders are relatively complex internally, and how many lifting operations need to be carried out during filling to fully fill each position of the hydraulic oil. Therefore, try to add as much as possible, and then test and run the machine empty to see if it reaches the rated position.
Construction electric elevators outside the lightning protection range
Wanghua.Secondly, the lifting platform is driven by electrical energy and lifted by the hydraulic system. During operation, it is necessary to avoid irregular operations. To ensure the normal and orderly operation of the lifting platform and achieve the ideal unloading level, timely inspection of various functions is essential.
Implementing multiple shifts of homework should fill in and submit records according to regulations.
When the landing door is closed, the full width of the lifting passage opening should be covered.
