Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient,HaMobile electric elevator, 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, small size, and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.
Ha.In addition, when adding hydraulic oil, it is necessary to ensure the quality of the hydraulic oil, as some hydraulic oil manufacturers will choose hydraulic oil with poor quality. Hydraulic oil such as hydraulic lifting platforms not only cannot have any effect on folding arm elevators, but also affects the working efficiency of folding arm electric elevators due to deterioration issues.
The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve,Ha10 meter electric elevator, hydraulic control one-way valve throttle valve, 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.
.Especially suitable for steel structured factories, suitable for both indoor and outdoor installation.
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
Installation and dismantling personnel and drivers should hold certificates to work.
When the distance between the outer edge of the construction electric elevator and the edge line of the external overhead power line cannot meet the requirements in the table above, effective protective measures should be taken.
There is a certain itinerary.
Setting requirements: The landing door should be standardized and tooled.
Quality inspection report.The quality of the standard section should comply with the product manual and specification requirements.
Construction electric elevators outside the lightning protection range
The setting of the cable guide frame should comply with the user manual and regulatory requirements.
Acceptance: Concrete strength grade C30, strength testing report.
Promise and keep promise.During loading and unloading, the horizontal distance between the edge of the cage door and the edge of the landing station should not exceed 50mm.
Only after the operation of professional personnel can the suspension cage movement be restored.
Use floor doors and cage door devices on construction sites where conditions permit.
Ha.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,HaStage electric elevator, 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.
Manual pump: When the system malfunctions, the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position
The entrance of each landing platform must be equipped with a landing door which must open towards the landing platform side, and the door bolt must be set on the side next to the construction electric elevator.
