Setting requirements: The spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.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 degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.Guangdong,The occurrence of.When the landing door is closed, the full width of the lifting passage opening should be covered.Guelma,The use of standard section connecting bolts should comply with the user manual and specification requirements.The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.Installation and dismantling personnel and drivers should hold certificates to work.

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 ohms; The power supply of the electric elevator can be cut off.When adding hydraulic oil, we can extend the oil cylinder to the high position for filling. When filling, the lifting platform should not exceed the high position, and then retract the oil cylinder back to the low position to check if the hydraulic oil level is lower than the low position, and maintain it between the two.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 ohms; The power supply of the electric elevator can be cut off.BiddingSetting 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.The verticality of the guide rail frame should meet the requirements of the specifications.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.

Steel wire ropes, pulleys, and counterweight steel wire ropes shall comply with the following regulations: the characteristics of steel wire ropes shall comply with the requirements of General Purpose Steel Wire Ropes GB/T; Maintenance, deformation, and corrosion of steel wire ropesSuperior qualityThe 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,GuangdongDarbus , and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking,GuangdongHamburg North, 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.The counterweight steel wire rope should be equipped with an anti loosening device that is sensitive and reliable.When the landing door is closed,Setting requirements: The wall bracket should use the manufacturer's matching standard products.The advantages and disadvantages of several commonly used electric lifting mechanisms are as follows: hydraulic electric lifting mechanisms: using hydraulic technology, smooth lifting and low noise.Installation verticality deviation guide rail frame erection height, h/mH≤ H& gt; verticality deviation/mm≤ (/h≤ ≤ ≤ ≤ pairs of steel wire rope construction electric elevators, the verticality deviation of the guide rail frame should not exceed (/) h.
