MJ-400
Portable Valve Grinding
Machine is a
new generation of products that is adeveloped to adapt to on-site
maintenance gate valve. It has the advantages as below: the
reduction of labor intensity, improving labor efficiency,
replacing imported products, educing the maintenance cost. It is
widely used in petroleum, chemical industry, steel mills, power
plants and so on.
1)
The machine is equipped with a three - paw frame, and the machine
can be fixed on the valve body at work to reduce the extra work
strength and ensure the stability of the machine at the same
time.
2)
The front end of the spindle is equipped with a telescopic sleeve
controlled by a pressure spring, and the axial pressure can be
adjusted to make the spindle working in a flexible working
state.
3)
The main shaft output end adopts universal coupling, which can
compensate the perpendicularity deviation of the machine
installation to a certain extent.
4)
The drive system is driven by adjustable speed motor, which can
be adapted to the coarse and fine grinding of various valves, and
the operation is convenient. The motor can operate in positive
and negative two directions.
5)
The three - paw frame is three - claw synchronizing. After
replacing the sand paper, the precision of the repositioning is
high.
