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.
The list of materials for making landing doors is as follows: Table 1: List of materials for making landing doors. Landing doors should be installed at the entrance of each landing station, and the landing doors should function properly.
Alexandria.The usual operation of landing and docking. The installation position of the upper limit switch should comply with the following: when the lifting speed is less than 0.8m/s, oil cylinder pin shafts and bearings intermediate 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,Alexandria200 kg electric elevator, 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, tighten the joint, clean it with compressed air, and then return it to the oil tank and connect the pipeline.
.Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.
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.
Implementing multiple shifts of homework should fill in and submit records according to regulations.
Double layer steel mesh: The diameter of the steel bars is 12mm, with a spacing of 200mm.
Items and other miscellaneous items.
Setting requirements: The wall bracket should use the manufacturer's matching standard products.
build.Every theater is a public place with a large number of people, and safety considerations should be taken into account in stage design. According to relevant national regulations, in order to prevent accidents caused by the crushing of electric elevators or improper control by drivers. Electric elevators should be equipped with the following necessary safety devices to ensure that the car of the electric elevator stops rising or falling in a timely manner.
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.
Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient,AlexandriaSmall and simple electric elevator, 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.
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
Honest management.The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve,AlexandriaElectric single arm 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, 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.
When a single steel wire rope is excessively stretched, the Electrical safety device shall stop the operation of the electric lift.
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.
Alexandria.Especially suitable for steel structured factories, suitable for both indoor and outdoor installation.
Acceptance: Concrete strength grade C30, occupying a relatively small area, improving the utilization rate of the wellbore area.
