SXT-IV washer-extractor has professional computer control system, excellent capacity and super function, it contains 30 programmable procedures and 5 standard programs, and all design is near to human feature. User can control work liquid-level, wash temperature, wash time, and efficiently satisfy with wash request in different situations. Creative structure from drum design of excellent stainless steel ensures that machine lifespan is prolonged during overload situation. Adopting advanced limit principle to design outer vat is made by stainless steel, it can resist corrosion and have high stability. Different design of high-strength big shaft-pedestal and high-accuracy short shaft can effectively reduce transverse vibration moment. Bearing of major shaft adopt high accurate core, so that prolong use lifespan and durability. Seal technology of major shaft have acquired state invention patent, double design of waterproof, imported seal material of fluorine rubber, special compartment design, assuring that protect bearing and improve use lifespan. Because of scientifically adding overload weight at the front of suspended object, gravity of suspended object and center of vibration source can combine in working state, so that reach perfect balance of suspended object. Spring of vibrationproof system adopt special design of recovery moment according to different vibration of suspended object front and back, so that finish the best vibrationproof efficiency and effective vibration-reducing rate to 98%. Frequency-conversion drives, endless speed adjusting quiet stable rum. High-quality bearing, long lifespan. Imported seal material of major shaft, patent technology design, effectively resists high temperature and super acid- alkali. Stainless steel panel, high corrosionproof (back panel is galvanization). Safe door-lock union device of patent technology ensure safety. Five compartment automatic detergent adding system, injection moulding structure of nylon combination, high corrosionproof. Larger diameter loading door and human design conveniently load and unload, so that reduces labor strength. Adopting steam heating, hot water heating.
