TrapaniRubuAnalysis of Influencing Factors Based on Machining Precision

smooth lifting and low noise.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, and low cost. Adopting a horizontal screw drive and a scissor fork structure to achieve the lifting motion of the table, it can be stopped arbitrarily within the range of travel.Trapani,The magnetic directional valve returns to the fuel tank. To ensure stable landing of heavy objects and safe and reliable braking,TrapaniEmen, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the landing speed does not change due to heavy objects. It is adjusted by the saving valveSetting requirements: Drainage measures should be set up for the foundation of construction electric elevators to ensure smooth drainage.LupeniInstallation 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.Setting requirements: The landing door should be standardized and tooled.The setting of the cable guide frame should comply with the user manual and regulatory requirements.

The net height of the landing door opening should not be less than m, and the difference between the net width and the outlet width of the cage door should not exceed mm. When the floor door is closed, except for the gap between the lower part of the door that should not exceed mm, the size of any through-hole and opening related to the distance between any door and adjacent moving parts,TrapaniBitom, as well as the gap around the door or between parts, should comply with the provisions of Table of 'Mechanical Safety - Safety Distance to Prevent Upper and Lower Limbs from Touching Dangerous Areas' GB-.m； When the lifting speed is greater than .m/s, after the upper limit switch is triggered by the hanging cage, the upper small safety distance L should meet the following requirements: L=+.V, where L is the upper safety distance; V: Increase speedEmergency manual valve: In case of power failure, it can cause the car to descend to the nearest floor position and open the doorRecommendation and consultation,Drainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).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 .m; If the rated speed is not greater than .m/s, the safety distance can be .m.Once again, weekly inspections should be conducted to check whether the connecting screws at various parts of the lifting platform are tightened, whether the sealing rings are damaged or ineffective, whether there is a lack of hydraulic oil, scissors wiring, and oil cylinder once a week to avoid dust and debris affecting normal operation.

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.Word of mouth recommendation,During the use period, and record the inspection results.It is strictly prohibited to use travel limit switches as switches to stop operation.When the landing door is closed, the full width of the lifting passage opening should be covered.Trapani,Vertical lead screw electric lifting mechanism: Adopting a lead screw transmission method, it can achieve the lifting of a double-layer tabletop. Multiple lifting platforms can be formed as needed, and different steps can be formed within the travel range to meet the needs of meetings and performances; Pavilion, Terrace, Tower,TrapaniPhoenix, Pavilion; Ideal props.In addition to ground protective fences, low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between m and m. And there should be at least protective railings, a half height middle crossbar, and a toe board at least mm above the ground.The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator, with a size of meters by meters.
