YongjiHand proThe bearing capacity of the ground under the concrete foundation plate should be greater than 0.15Mpa.
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.
Yongji.The water cooling of hydraulic stations is generally tubular water cooling. The selection is based on the heat load to calculate the heat exchange area, while the air-cooled electric elevator uses an air cooler to calculate the heat exchange capacity based on the heat load. Then, the selection calculation is carried out under the condition of satisfying the flow rate. So, these two types of cooling are different and have significant differences.
Setting requirements: The wall bracket should use the manufacturer's matching standard products.
.Civil engineering advantages: The pit depth of the guide rail type lifting platform is generally around 150-300mm, and the top layer is not affected. It can be customized according to the location and environment.
It is reported that a fixed electric elevator has good lifting stability and can only be used for fixed operations, making high-altitude operations easier
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.
The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator, with a size of 8 meters by 2 meters.
When adding hydraulic oil, we can extend the oil cylinder to the high position for filling. When filling,YongjiScissor fork electric elevator, 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 performance: Electric elevators not only have the safety device of traditional traction elevators,YongjiFully automatic elevator electric, but also have an overflow valve to prevent excessive system pressure during upward movement
assets.The connection method and angle between the wall bracket and the building structure should comply with the requirements of the user manual.
Monthly maintenance and inspection of hydraulic lifting platform rollers,YongjiSmall electric automatic elevator, oil cylinder pin 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, 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, remove the oil filter, clean it with compressed air, and then return it to the oil tank and connect the pipeline.
Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination, 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.
From the above comparison, it can be seen that hydraulic electric lifting mechanisms have stable lifting, low noise, long service life, large load bearing capacity, and are relatively simple, making them suitable for use in stage equipment.
Lets see.Chain type electric lifting mechanism: With a good guiding mechanism, the horizontal distance between the closed cage door and the closed landing door should not exceed 150mm. Otherwise the oil temperature protection device sends a signal to suspend the use of the elevator. The elevator can only be started when the oil temperature drops
During normal operation, measures should be taken to make it meet the requirements, or side protection devices at the entrance of the landing station that meet the requirements should be equipped. The distance between any opening between the side protection device and the hanging cage or landing door should not exceed 150mm.
The quality of the standard section should comply with the product manual and specification requirements.
