DB212 Series High Pressure High Temperature Package Dyeing Machine Main features: 1. It has two dyeing modes, air pad type
and full flood type to choose for different dyeing techniques. 2. Unique construction commutation (patent
no. ZL200520074155.6) , the high efficiency heat exchanger and DBNP
pump are combined integrative, (patent no. ZL200520074154.1). The
are designed without external circulation pipes, saving space 25%. 3. Special compact designed calandria heat
exchanger is installed outside, in same heat exchange conditions,
it can achieve the best exchange effect of heating and cooling. 4. Main pump are controlled by stepless
flowing rate of inverter, it can achieve the same dyeing effect
according to different dyeing techniques, and save power
consumption when starting and de-loading. 5. Special steady commutation mechanism
allows liquid flow to change direction without stopping main pump,
thus increasing liquor circulating times to improve level-dyeing
property. 6. With multi-function intelligent
computer, it simplified the water inletting, draining, eternal
flowing, internal flowing, and etc. operation. 7. Pressure dewatering to decrease the
water containing in package yarn. 8. Dyeing with low liquor ratio of 1:6 can
save dyestuffs, chemicals, steam and water thus decreasing the
drainage. 9. The high efficiency heat exchange
between the liquid stream and dyeing liquor improve the speed of
dyeing technique process, shorten the time. 10. Rapid loading creel, easy to take out the package, thereby
reducing the labor intensity and saving the working efficiency. Standard structure: 0. All metal parts of the dyeing machine
coming into contact with the dye liquor are made of high quality
anti-corrosion stainless steel. 1. High efficiency unique DBNP pump with
mechanical seal mechanism are controlled by inverter (used for more
than 18.5KW), the flow can be controlled stepless. 2. Vertical dyeing tank, rapid-locking lid
with counterweight and triple safety interlocking mechanism. 3. Patented automatic direction changing
liquor commutation. 4. Patented unique high efficiency
shell-and-tube heat exchanger. 5. Open type dosing tank and ration feeding
system. 6. Main tank automatic pressure increasing
and decreasing system. (air pad type) 7. Circulation liquor condensator. (full
flood type) 8. High accurate pressure differential
sensor to control the liquor level. ( air pad type) 9. Multi-function intelligent computer and
PLC to control the feeding, water inletting, draining, temperature
rising, decreasing and keeping, and the rising etc. automatically. Options: 10. Auxiliary vessel with equal capacity for direct heating device,
which is composed of feed pump and mixing system. 11. Various kinds of yarn carrier for loose fibre, hank, zipper,
and yarn beam etc. 12. Hot drain. 13. Progressive dosing system. 14. Secondary water feeding and draining. 15. De-loading cones and their accessories. 16. Accessories for dyeing, such as cone, intermediate |
