Hydraulics are the powerhouse in the back of an excavator, turning easy lever actions into tough growth and bucket actions. Our new electro-hydraulic innovation, referred to as Impartial Metering Valve Era (IMVT), approach Volvo excavator hydraulics are turning into much more intuitive, providing operators smoother regulate and extra environment friendly paintings on building and basic excavation jobs. This innovation isn’t with regards to more potent machines, however smarter ones that care for duties sooner and with larger precision.
IMVT marks a departure from the standard automatically coupled hydraulic techniques and introduces clever digital regulate with a large number of variables. The consequences are as much as 25 p.c stepped forward gasoline potency and higher operator regulate.
One key distinction is the closed-center valve regulate machine, which is able to forestall or reduce hydraulic float going via the primary regulate valve (MCV) when there’s no call for for a hydraulic actuator. Different regulate techniques have an open-center valve regulate machine so hydraulic float is going in the course of the MVC it doesn’t matter what. That is one among the explanation why IMVT lowers gasoline intake and removes the will for an ECO mode.
Any other distinction is that IMVT senses and controls each and every aspect of the chamber of a cylinder with out hydraulic spools and hydraulic pilot traces for extra actual regulate.
IMVT additionally replaces conventional spools with poppet and electro-hydraulic valves within the MCV, lowering drive losses and optimizing valve regulate in accordance with load prerequisites. This results in sooner cycle instances, stepped forward regeneration and diminished float loss.
And through getting rid of hydraulic pilot traces, IMVT considerably reduces the chance of leaks and harm. The absence of spools and pilot traces simplifies repairs and repair, whilst built-in sensors toughen diagnostics via a devoted provider instrument.
How IMVT Complements Excavator Efficiency
Operators will see higher efficiency in particular usually excavation and truck-loading eventualities the place most productiveness is a very powerful. IMVT options come with:
Creep mode: Splendid for application and piping programs, creep mode separates the 2 primary hydraulic pumps, making sure a relentless touring pace irrespective of different hydraulic actuator activations.
Movement precedence purposes: Operators can customise settings for boom-up, swing and different purposes, optimizing hydraulic precedence in accordance with the duty and lowering loading cycle instances, particularly in shut proximity to vans.
Diminished bouncing: IMVT addresses operator fatigue led to through bouncing as it complements the precision of the excavator’s actions, which is a very powerful when dealing with subtle or heavy lots within the bucket.
Advanced Convenience Power Keep an eye on (CDC): CDC transforms the operator enjoy through enabling actual monitor regulate the use of simplest an index finger on curler proportional switches. This reduces fatigue and will increase potency — particularly in difficult terrain.
Auto warmup: In chilly running environments, IMVT’s auto warmup function successfully warms up the hydraulic circuit with out exterior warmers, getting the excavator able rapid with out burdening the hydraulic machine.
Customizable regulate purposes: IMVT gives a variety of customizable purposes, together with growth up – swing precedence; growth up – commute precedence; and growth down pace regulate. Those options permit operators to tailor the excavator’s efficiency to express duties, improving each potency and operator pride.
Volvo Excavators with IMVT
IMVT is recently to be had on Volvo EC550 and EC530 excavators. In large part due to IMVT, those 50-ton machines be offering digging and lifting forces most often discovered within the 60-ton vary.
IMVT was once to start with offered on those fashions because of constant call for for 50-ton excavators, however there may be attainable for enlargement to different fashions. A case learn about confirmed that an EC550 excavator supplied with a bigger bucket burned much less gasoline than an EC480, attaining extra manufacturing with much less gasoline intake. Further research proved that IMVT supplies a notable building up in engine energy, digging drive, swing torque and tractive drive, boosting productiveness through as much as 20 p.c and making improvements to gasoline potency through 25 p.c.
The Long run of Excavator Hydraulics
The advent of the electro-hydraulic machine with Impartial Metering Valve Era represents an important development in excavator generation. Through combining clever digital regulate, unbiased cylinder regulate and customizable purposes, IMVT is surroundings a brand new usual for controllability, potency and flexibility in heavy apparatus.
Excavators supplied with IMVT now not simplest outperform conventional hydraulic techniques but in addition give a contribution to decrease gasoline intake, enhanced operator convenience and more straightforward repairs. Should you’re on the lookout for a brand new excavator within the 50-ton vary, succeed in out to a close-by Volvo broker and ask them about machines supplied with this ground-breaking generation.
