Hydraulic elevator should pay attention to a model

Hydraulic elevator car rises by uniform linear motion is the flow through the pump to the fuel tank of a certain oil to the plunger to inject up to achieve uniform, down when the uniform motion of the fluid through the cylinder to a certain flow into the tank, the car weight to the plunger down to achieve uniform, but also have a speed problem.

Advantage of the hydraulic elevator machine room requirements is low, a greater carrying capacity, fewer security issues. The disadvantage is lifting height is limited, generally not more than 6-story building; elevator speed can not be quickly, usually not more than 1m / s.

Freight elevators, especially the large tonnage (2t above) freight elevators, hydraulic elevators should be preferred. When the old building new lift machine room and is difficult to find the right shaft, the hydraulic lift at this time show a clear advantage. In addition, the villa set for 2-3 story residential elevators, hydraulic elevators is undoubtedly the best model.
