Product Description
Roots water ring vacuum pump
set
Summary:
JZJ2B series Roots
water ring vacuum unit is composed of ZJ Roots vacuum pump as the
main pump and 2BV or 2BE water ring vacuum pump or Roots water ring
unit as the fore pump, It not only can suction the general gases,
but also can suction the other gases that contain moisture or a
small quantity of dust. Compared with the general mechanical vacuum
pump, it is not easy to be polluted by oil, moisture and dust. And
compared with general water ring vacuum pump, it has higher vacuum
and bigger pumping speed when it works in the high vacuum.
Several types of the
package units:
◆Roots pump+water ring vacuum
pump:The function of the water ring vacuum pump is to form the
pre-vacuum for the Roots pump. Presently, water ring vacuum pump
2BV,2BE1 with higher ultimate vacuum degree are mostly used
as fore pump.
◆Roots pump+Roots pump+water ring
vacuum pump:When use one set of the Roots pump, especially
connecting with the water ring vacuum pump, the limited vacuum of
the whole unit is much lower with the restricted scope . But to
use two sets of the Roots pumps in series and connect them with
the water ring vacuum pump can improve the whole limited vacuum
effectively.
◆Roots pump+Roots pump+Roots
pump+water ring vacuum pump:If the two Roots pumps and the water
ring vacuum pump unit still dose not satisfie the requirements of
the vacuum , another Roots pump can be added. These series Roots
units are used extensively in some high vacuum technics of the
vacuum freezing or dry process.
Normally, to choose the water ring vacuum pump as the fore pump
is better than to choose the others because the following
reasons:
First, the water ring vacuum pump can pump plentiful coagulable
steam. And this advantage is more obviously when use the gas-down
and oil seal mechanical vacuum pump as the fore pump because it
is poor in pumping the coagulable steam.
Secondly, to use the solvent as the operating liquid will make
the oil bad. Sometimes, the system is not allowed the pollution.
Furthermore, to choose the package units, it is necessary to make
the working vacuum five or ten times of the limited vacuum in
order to achieve the best performance of the package units. i.e.
working vacuum>=limited vacuum *(5~*0).
