TodelgekoRechaThe hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve,TodelgekoLarge electric 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,TodelgekoMicro electric elevator, 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.
As a material loading and unloading equipment recognized by customers in the lifting platform, civil engineering, and operating costs. The editor of the electric elevator will provide a detailed analysis: the advantages of the product are that the equipment bears a large load, can achieve multiple points, and can be controlled up and down floors to achieve safe use.
Todelgeko.Correct use can also greatly improve work efficiency. So how should it be used?
Setting requirements: The quality of the standard section should meet the requirements of the product manual. Before installing the construction electric elevator, all components should be inspected, and standard sections and other components with severe wear and deformation should be replaced.
.Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.
Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
The counterweight guide rail should meet the specification requirements.
Before use, we should observe whether there is any damage to the electric elevator. We can conduct a no-load test to raise and lower it. If there are any damaged parts, they should be replaced in a timely manner to prevent major accidents.
Setting requirements: When the distance between the outer edge of the construction electric elevator and the external overhead power line cannot meet the requirements of a small safety distance, the protective measures taken should comply with the specification requirements.
Trustworthy.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, with a size of 8 meters by 2 meters.
The motor of the hydraulic guide rail lifting platform is set around the wellbore,TodelgekoIndoor electric elevator, occupying a relatively small area, improving the utilization rate of the wellbore area.
When the landing door is closed, the full width of the lifting passage opening should be covered.
agent.Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descent
Is there a relevant rule requirement for the cleanliness of hydraulic stations?
Safety grounding device. In order to protect against electrical equipment. The metal casing of electrical equipment and the metal structure of electric elevators should be equipped with a safety grounding device. The grounding wire should operate multiple wires, and the neutral wire should not be arbitrarily held as a safety grounding wire. Its grounding resistance should not exceed 4 ohms; The power supply of the electric elevator can be cut off.
Todelgeko.The setting of the cable guide frame should comply with the user manual and regulatory requirements.
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.
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.
