Belo Horizonte
Belo HorizonteInstallation and dismantling personnel and drivers should hold certificates to work.
Principle of electric elevator rotary valve: When the electric elevator rises, the rotary valve will automatically open. To close the plug valve, and then turn the transmission handwheel to lower the plug and achieve sealing.
Belo Horizonte.Precautions for safe use of electric elevators: Before use, remove any obstacles or debris near the electric elevator that may hinder operation, and check whether the operating handle can be used normally.
Work is essential, and the main protective accessories include safety belts guardrails, protective covers, platforms and stairs, etc.
.Setting requirements: The installation and dismantling workers, electricians,Belo HorizonteElectric 6-meter elevator, and other operators of construction electric elevators should have special construction operations.
When the landing door is closed, it can cause the car to descend to the nearest floor position and open the door
Setting requirements: The foundation and foundation of the construction electric elevator should meet the requirements of the user manual. Before installing the construction electric elevator, the foundation should be inspected and accepted according to the requirements of the specifications. Only after passing the inspection can the installation be carried out.
The pressure joint between the pipe joint and the rubber hose fails prematurely causing oil leakage or pipe explosion. The oil temperature rises due to frequent action of the overflow valve.
The use of standard section connecting bolts should comply with the user manual and specification requirements.
Where can I find it?.The 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, 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.
Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position, it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking,Belo HorizonteFully automatic elevator electric, stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset, and installed in the machine room,Belo HorizonteFixed electric elevator, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
The full height landing door should meet the following requirements: the net height of the landing door opening should not be less than 0m. In special circumstances when the net height of the building entrance is less than 0m, it is allowed to lower the height of the lower door opening, but in any case, the net height of the lower door opening is not less than 8m. (Article 1 of GB26557-2011)
Secondly, for the replacement of hydraulic oil on the lifting platform, it can be replaced once a year. The hydraulic oil must be clean, and after changing the hydraulic oil, it must be automatically lifted and lowered 2 to 3 times to ensure that the air in the oil cylinder is completely discharged, maintain sufficient space, and ensure that the lifting platform can be lifted to the rated lifting height.
Quality department.When applying a normal force of 300N to any position on either side of the door using a rigid 5000mm2 square or circular flat surface in the locked position of the landing door, the door should be able to withstand and have no deformation; - Deformation not exceeding 30mm; After the test, it worked normally.
Setting requirements: Buffers should be installed below the suspension cage and counterweight running channel.
Mechanical devices controlled by cage movement should not be used to open or close the landing door.
Belo Horizonte.The full height landing door should meet the following requirements: the net height of the landing door opening should not be less than 0m. In special circumstances, when the net height of the building entrance is less than 0m, it is allowed to lower the height of the lower door opening, but in any case, the net height of the lower door opening is not less than 8m. (Article 1 of GB26557-2011)
The setting of the cable guide frame should comply with the user manual and regulatory requirements.
The spacing between wall brackets and the height of guide rails above the high attachment point should comply with the requirements of the user manual.
