LQRY Hot oil pump overview
LQRY series of hot oil pump, in China's heating medium heating system has been widely used, has entered the oil, chemicals, rubber, plastics, pharmaceutical, textile, printing and dyeing, road construction, food and other industrial fields, mainly for the transport of solid Particles of weakly corrosive high temperature liquid, the use of temperature370 ℃, is an ideal hot oil circulation pump.
LQRY Hot oil pump model meaning
LQRY Hot oil pump structural features
LQRY series of hot oil pump is the unit digestion and absorption of
foreign oil pump based on the development of the second generation
of products, the basic structure of the single-stage single-suction
cantilever foot support structure, the pump inlet for the axial
suction, the export center vertical up, and The motor is mounted on
the base.
LQRY series of hot oil pump support with double-end ball bearing
support structure, the front end of the use of lubricating oil
lubrication, the rear end of the use of grease lubrication, the
middle of a guide tube, to observe the sealing situation and
recovery of heat transfer oil.
The use of self-heating structure, changing the traditional
water-cooled structure, so that the structure is simple, small
size, saving operating costs, good performance, the use of
reliable.
LQRY series of hot oil pump, (1) the use of packing and mechanical
seal in the form of a combination of packing with high temperature
filler, with good thermal chase, and mechanical seal is the use of
high mechanical strength, good wear resistance Carbide material
ensures high temperature sealing performance.
(2) the use of third-generation polytetrafluoroethylene (PTFE) to
do lip seal, the sealing performance of a leap, than rubber seals
improve reliability 25 times, corrosion resistance is extremely
strong.
LQRY Hot oil pump safety of the unit
1. Pump installation is good or bad operation of the pump and the
life of a very important impact, so the installation must be
carefully carried out, not hasty
Act.
2. Pump installation tube height, length and diameter should meet
the calculated value, and strive to short, reduce unnecessary
losses (such as elbow, etc.)
3. Suction and discharge piping should be a pipe rack, the pump is
not allowed to bear the load of the pipeline.
4. The installation site should be wide enough to facilitate
maintenance work and good heat dissipation.
5. Installation order:
1) the unit on the basis of buried bolts on the basis of the base
and the base between the pair of mats, for use is looking for.
2) loosen the coupling, with the level on the pump shaft and the
base, respectively, by adjusting the wedge pad to the unit to the
level, after correction, appropriate tightening
Anchor bolts to prevent walking.
3) Fill the base and anchor bolts with concrete.
4) after the concrete dry, check the base and the foot screw check
whether there are bad or loose and so on, check the qualified
should be tightened after the anchor bolts, and
Recheck the pump level.
5) correct the coaxiality of the pump shaft and the motor shaft,
the deviation in the outer circumference of the coupling allows 0.1
mm, the gap between the two coupling plane should ensure 2-
3 mm, the maximum and minimum gap difference shall not exceed 0.3
mm on the circumference of the two coupling ends.
6) After connecting the tubing and determining the direction of
rotation of the prime mover, connect the coupling again and check
the coaxiality again.
7) in the actual trial run 3-4 hours after the final inspection, if
there is no adverse phenomenon that the installation of qualified.
8) During the installation process
