Secundum ad characteres Hydrau sentinam, et hydrau ratio solebat ab Hydraulicorum CAVATOR est roughly dividitur in tres genera: quantitatis ratio, variabilis system, et quantitatis et variatur ratio.
(I) quantitative ratio
In quantitatis ratio usus ab Hydraulicorum excavators, et fluxus est constans, id est fluxus non mutare cum onus, et celeritas solet accommodetur per throttled. According to the quantity and combination form of oil pumps and circuits in the quantitative system, it can be divided into single pump single loop, double pump single loop quantitative system, double pump double loop quantitative system and multi-pump multi-loop quantitative system.
(II) variabilis ratio
In the variable system used in hydraulic excavator, stepless speed regulation is realized by volume variable, and there are three adjustment methods: variable pump-quantitative motor speed regulation, quantitative pump-variable motor speed regulation, and variable pump-variable motor speed regulation. Variabilis ratio adoptavit ab Hydraulicorum Cavator plerumque adoptat compositum variabilis sentinam et quantitatis motricium ad animadverto in stallis variabilis, et omnes duplici exhaurifera et duplex circuits. Secundum utrum variabiles duo circuitus refert possunt dividitur in duas species, sub-potentia variabilis ratio et totalis variabilis ratio. Each oil pump of the sub-power variable system has a power regulating machinery, and the flow change of the oil pump is only affected by the pressure change of the circuit in which it is located, which has nothing to do with the pressure change of the other circuit, that is, the oil pumps of the two circuits independently carry out constant power regulating variables, and the two oil pumps each have a bucket of engine output power; Duo oleum soliferis in pleno virtute variabilis ratio sunt libratum per totalis potentia regulating mechanism, ita ut adductius angulus duorum oleum soliferis semper idem
Et synchronization variables et negotiationis sunt idem. Quid determinat fluunt rate mutatio est summa pressura systematis, et potentia duo oleum soliferis non est idem in range de variables. Regulating mechanism habet duas formas mechanica japony et hydraulicarum junctura.
