What is the noise level of DRY plants?
I imagine that since the engine is not submerged in the oil tank, they will be greater than in conventional ones.
Hello Carlos,
The use of DRY (external) motors in hydraulic power plants is normally associated with a higher noise level because the motor is external and not submerged. The design of this type of motor is very important, as it helps to improve noise and efficiency. In the case of our equipment, we have carried out design work on DRY motors based on: the design and material of the casing to improve motor cooling; the use of soft sliding bearings; and motors without forced ventilation, among others. All these characteristics lead to an improvement in the noise and efficiency of GMV DRY motors. This allows us to offer products with DRY motors, where the difference in noise with internal motor (conventional) power plants ranges between 0 – 2 dB, depending on the model and characteristics of the installation.
Greetings,
What type of elevators is the Dry central unit recommended for? Or does it make no difference whether one or the other is installed?
Hello Jose!
The use of Dry central units is recommended in homelifts or platform lifts, since the use of this type of motor reduces motor consumption. DRY central units also provide noise levels equivalent to submerged motors in conventional central units thanks to their design.
Dry motors are also being developed for use in installations with lifts of up to 450 kg and approximately 5 stops. This allows for a greater reduction in motor consumption.
Greetings!
I have a conventional single-phase GMV control unit for a hydraulic lift with a Carlos Silva control unit. When the lift starts up, the control unit makes a very hoarse sound. Based on my experience, I understand that this is not its normal sound. I have seen that they have not connected the pressure switch, but they have not left any diagrams of the control unit either. My question: could the hoarse sound of the control unit be due to the pressure switch not being connected?
Good morning Manuel,
In order to give a more specific answer to your question and determine where the noise is coming from (probably from the pump or the motor or the coupling in them), we would need more information about the power plant you have installed.
In any case, and answering your question, the fact that the pressure switch is not connected is not the cause of the noise.
Greetings.

Well, I'm super delighted and it's the first time I've been involved in these things. I have no experience. I apologize, thank you.
