Principle of electric elevator rotary valve: When the electric elevator rises
The advantages and disadvantages of several commonly used electric lifting mechanisms are as follows: hydraulic electric lifting mechanisms: using hydraulic technology, 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.

Protective measures should comply with regulatory requirements.
.Setting requirements: Drainage measures should be set up for the foundation of construction electric elevators to ensure smooth drainage.
When the landing door is closed, the full width of the lifting passage opening should be covered.
Setting requirements: The verticality deviation of the installation of the guide rail frame of the construction electric elevator should comply with the requirements of the user manual and specifications, as specified in the above table.
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.
It is strictly prohibited to use travel limit switches as switches to stop operation.
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, suitable for both indoor and outdoor installation.
Remind customers that there are still many areas to pay attention to when maintaining and maintaining the lifting platform. We also hope that customers and friends can pay more attention when using it to ensure the safety of personnel and property, regularly maintain and extend its service life, and create greater benefits for the enterprise. What is the matching degree of electric elevators? Everyone has always been confused. In short, the matching degree of electric elevators is how the height of the electric elevator can be combined with the operating height. Electric elevators are not used frequently, We suggest considering purchasing a guide rail electric elevator or a scissor fork electric elevator. The scissor fork electric elevator can achieve a maximum load capacity of 100 tons, which effectively solves the problem of load capacity. If the frequency of use is too high and the height is relatively high,MingshanPortable electric elevator, we recommend using a guide rail electric elevator. This type of electric elevator is not easy to malfunction under high-frequency operation, By solving the load capacity and frequency of use,MingshanSimple electric elevator, the matching problem of electric elevators is effectively solved. Concept of electric elevator rotary valve: The electric elevator rotary valve is a type of valve that quickly opens and closes, and the rotary valve can reduce oil pipeline channels and optimize line settings.
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
Mechanical devices controlled by cage movement should not be used to open or close the landing door.
average method.Acceptance: Concrete strength grade C30, strength testing report.
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
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.
Mingshan.Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, 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, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed.
Speed limiter. To prevent the driving speed from exceeding the normal speed. A speedometer should be installed (not required for floors below or including the second floor), which is an individual mechanism that is integrated with a safety clamp; The entrance and exit of the passenger compartment should be equipped with safety doors.
