SacramentoElectric three wheel elevatorAnalysis of common faults and strategies in maintenance

Every theater is a public place with a large number of people, and safety considerations should be taken into account in stage design. According to relevant national regulations, in order to prevent accidents caused by the crushing of electric elevators or improper control by drivers. Electric elevators should be equipped with the following necessary safety devices to ensure that the car of the electric elevator stops rising or falling in a timely manner.

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.

Sacramento.The up travel (limit) switch should be of the automatic reset type.

High lifting height, using side mounted oil cylinders, stable operation, noise free, easy maintenance, and longer service life.

.The advantages and disadvantages of several commonly used electric lifting mechanisms are as follows: hydraulic electric lifting mechanisms: using hydraulic technology, oil pipe, and motor of the aluminum alloy electric elevator is good and whether there is any air leakage.

Work is essential, and the main protective accessories include safety belts, guardrails, protective covers, platforms and stairs, etc.

Word of mouth recommendation.The landing door should be in a normally closed state. Without the permission of the construction electric elevator driver the landing door shall not be opened.

Setting requirements: The installation and dismantling workers, and other operators of construction electric elevators should have special construction operations.

Model Example: Hanging Cage Specification: LABSC200/200TD3200x1500 Type I: 2900~3600 Type II: 2900~3600 Type V: 1800~250044003800 Technical Requirements: The load-bearing capacity of the foundation should be greater than P: P=(hanging cage weight+outer cage weight+total weight of guide rail frame+counterweight+load) x0.02 (kN).

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.

Quality Assurance.The scaffolding of the parking platform should be laid tightly and firmly.

Requirements for the operation platform of the construction lowering machine and the setting of the brake reset emergency stop switch: The shutdown device (emergency stop switch) should be able to stop or maintain the electric elevator (including the power driven door) in a non working state

Emergency manual valve: In case of power failure it can cause the car to descend to the nearest floor position and open the door

Sacramento.Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient, and the valve can be opened and closed at any time; The installation of a rotary valve reduces the friction of the sealing components; Compact structure,SacramentoElectric elevator, small size, and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.

For customers to use and operate the lifting platform for a long time, the editor briefly introduces how to maintain and repair the lifting platform: First of all, normal maintenance is mainly focused on prevention, resulting in costly repairs.

Work is essential, and the main protective accessories include safety belts, guardrails, protective covers, platforms and stairs, etc.
