The hydraulic press machine is one of the most widely used types of equipment in product molding and manufacturing. Since its appearance in the 19th century, it has developed very quickly. Due to its wide adaptability, the hydraulic press has been extensively used in various sectors of the national economy.
The first aspect is high speed, high efficiency, and low power consumption.
The second is its integration of mechanics, electronics, and hydraulics which help to perfect the whole hydraulic system by fully and reasonably using advanced mechanical and electronic technology.
The third one is its automation and intelligence which can realize automatic diagnosis and adjustment of the system and pretreatment of malfunction.
Last but not least, the hydraulic components are integrated and standardized to effectively prevent leakage and pollution.
As the two major components of the hydraulic press, the main engine, and the hydraulic system, due to the maturity of technology development, there is no big gap between domestic and foreign models. The main difference lies in the processing technique and installation. Good craftsmanship has obviously improved the function of filtering, cooling, and shock & vibration prevention. In terms of oil circuit structure design, hydraulic machines at home and abroad tend to adopt integrated and closed designs. Cartridge valves, superimposed valves, and composite components and systems are widely used in hydraulic systems. In particular, the integrated block can realize professional production, and what’s more, it has premium quality, reliable performance, and a short design cycle.
In recent years, the circuit composed of new hydraulic components developed on the basis of the integrated block also has its unique advantages. Since it does not require additional connectors, its structure is more compact with a relatively smaller volume and lighter weight. No pipe connection is required and thus eliminates leakage, vibration, and noise caused by oil pipes and joints. The logic cartridge valve has the characteristics of small size, lightweight, good sealing performance, low power loss, fast action speed, and easy integration. It appeared in the early 1970s and has since developed rapidly.
Mashine ya hydraulic press ni moja ya aina za vifaa zinazotumiwa sana katika kutengeneza bidhaa na utengenezaji. Tangu kuanzishwa kwake katika karne ya 19, imekuwa na maendeleo makubwa. Kwa sababu ya uwezo wake mkubwa wa kubadilika, vyombo vya habari vya majimaji vimetumiwa sana katika sekta mbalimbali za uchumi wa kitaifa. Jambo la kwanza ni mwendo wa kasi, ufanisi wa juu, na matumizi ya chini ya nishati. Mfano wa pili ni ushirikiano wa mitambo, umeme na hydraulics ambayo husaidia kukamilisha mfumo mzima wa hydraulic kwa kutumia kikamilifu na busara teknolojia ya hali ya juu ya mitambo na elektroniki. Tatu ni automatisering na akili ambayo inaweza kutambua automatiska utambuzi na marekebisho ya mfumo na pretreatment ya kasoro. Mwisho lakini si chini, vipengele hydraulic ni jumuishi na standardized kwa ufanisi kuzuia uvujaji na uchafuzi. Kama sehemu kuu mbili za press hydraulic, injini kuu, na mfumo wa hydraulic, kutokana na ukomavu wa maendeleo ya teknolojia, hakuna pengo kubwa kati ya mifano ya ndani na nje. Tofauti kuu iko katika mbinu ya usindikaji na ufungaji. Ufundi mzuri ni dhahiri kuboreshwa kazi ya kuchuja, baridi, na mshtuko na kutetemeka kuzuia. Kwa upande wa muundo wa mzunguko wa mafuta, mashine za hydraulic nyumbani na nje ya nchi huwa na kupitisha miundo iliyounganishwa na iliyofungwa. Cartridge valves, superimposed valves, na vipengele composite na mifumo ni sana kutumika katika mifumo ya hydraulic. Hasa, block jumuishi inaweza kutambua uzalishaji wa kitaalamu, na nini zaidi, ina ubora wa premium, utendaji wa kuaminika, na mzunguko mfupi wa kubuni. Katika miaka ya hivi karibuni, mzunguko ulioundwa na vipengele vipya vya hydraulic vilivyotengenezwa kwa msingi wa block iliyounganishwa pia ina faida zake za kipekee. Kwa kuwa haihitaji viunganishi vya ziada, muundo wake ni mdogo zaidi na kiasi kidogo na uzito mwepesi. Hakuna uhusiano bomba inahitajika na hivyo kuondoa uvujaji, vibration, na kelele inayosababishwa na mabomba ya mafuta na viungo. Logic cartridge valve ina sifa ya ukubwa mdogo, uzito mwepesi, utendaji mzuri wa kufuli, hasara ya nguvu ya chini, kasi ya hatua ya haraka, na ushirikiano rahisi. Ilianza kuanzishwa katika miaka ya 1970 na tangu wakati huo imeendelea kwa kasi.
