DJ Winch
Description
DJ series winch is a special equipment for geophysical exploration
and geological survey. It is mainly used with JHQ-2D integrated
digital logging equipment and can also be used with other logging
equipment. Most DJ series winches are anti-magnetic design,
stepless speed adjustment and automatic cable arrangement. The
performance can be applied to various geological prospecting areas.
DJ series winch equipment adopts frequency conversion motor, dc
motor, ac asynchronous motor as power source, and has a wide range
of speed regulation, smooth variable speed, convenient operation,
simple maintenance and so on. It can be used in geophysical
prospecting and geological survey work on the land, sea, plateau
(which is less than 5,500 meters above sea level) and other
environments on the earth.
Features & Benefits
1 Power
DJ series logging cable winch is powered by marine frequency
conversion motor, tombarthite permanent magnet DC motor, industrial
frequency conversion motor, dc motor, ac asynchronous motor as
power source. The selection of power source mainly considers the
factors such as high temperature and humidity environment, high
altitude environment, convenient field transportation, convenient
maintenance, long-term continuous operation and so on, so as to
ensure the reliability of the whole set of equipment.
2 Automatic cable arrangement function
Most DJ series logging cable winch has automatic cable arrangement
function, which ensures that the cable can be precisely and neatly
arranged when dropping and lifting, and can greatly prolong the
service life of the measuring cable. It is very important that the
winch has automatic cable arrangement function especially for steel
wire armored cable.
3 Automatic braking function
DJ series logging cable winch has the automatic braking function.
The winch can automatically stop when encountered in the use
process of emergencies, such as power outages, winch controller
failure and so on to keep the tube safe, so the tube will not fall.
4, Manual function
The DJ series logging cable winch is equipped with a handle, which
can drop or lift by hand without electricity in special
circumstances.
5. Accurate measurement of cable length
The DJ series logging cable winch has precise cable metering device
to ensure that the instrument has an accurate depth in the process
of lifting or dropping of cables.
6, Resistance to salt fog
Main components of DJ series cable winch for Marine geophysical
survey adopt high strength aluminum alloy as the material. The
surface is coated with electrostatic spraying, some fasteners are
stainless steel. It takes Marine ac motor as power source, and the
cable has kevlar wire and wire twisted rope core and it is coated
with polyurethane.
7, The magnetization
For the purpose of electric logging, magnetic logging and other
projects, the main structure of the DJ series logging cable winch
adopt high strength aluminum alloy as material, which ensures that
the logging cable can not be magnetized, and keep the minimum
amount of self and mutual inductance.
