Product Introduction:
Efficient and energy-saving: Top drive is highly efficient and energy-saving, which is very suitable for the future development direction of green and low-carbon drilling equipment.
Silent and environmentally friendly: no working noise from gearboxes and lubricating oil pumps; It also adopts closed water cooling and hydraulic station placement technology, with working noise not exceeding 50 decibels, significantly improving the working environment for workers.
Completely explosion-proof: The top drive main motor adopts sealed water cooling technology, and the main motor is sealed inside the top drive body, which can achieve true explosion-proof function.
Reliable performance: By adopting electric direct drive technology, the internal structure of the top drive housing should be kept as simple as possible to avoid major repairs caused by a small gear or bearing failure, and to maximize the reliability and continuous construction capability of the top drive.
Convenient maintenance: Metal debris generated by traditional mechanical top drive gear meshing can contaminate lubricating oil. The DQZ series top drive gearless reduction mechanism adopts immersion lubrication, which can effectively extend the service life of lubricating oil and reduce the frequency of lubricating oil replacement.
Precise control: When the top drive is used for directional tilting or after activating the torsional pendulum drag reduction function, it is necessary to precisely control the rotation angle and direction of the spindle.
