Parker Hannifin Parker Seminar on excavator solutions
In November 27, 2014, Shanghai BMW exhibition, at the Shanghai New International Exhibition Center held a conference room hannifen excavator solutions seminar. The following is the specific content.
Main contents of the seminar
1, Parker excavator products
(1) central main valve (1.5~10Ton) is opened
MC-3 characteristics of central main valve: suitable for 1.5~3.5T, chip structure, manual / hydraulic control.
The main valve AV-40 features: 1.5~4.5T, chip structure, manual / hydraulic control, internal confluence, load retention.
The main valve BCV-65 features: 4~6T, chip structure, manual / hydraulic control, internal confluence, load retention.
BCV-65 performance improvement: priority performance, P3 confluence, automatic idle signal to reduce fuel consumption.
MO90EX characteristics of the main central valve: suitable for 7~10T, overall structure, hydraulic control, confluence / priority, load retention.
Negative flow control main valve (10~80Ton)
Negative flow control main valve MO280EX characteristics: suitable for 20~32T, negative flow control, overall structure, hydraulic control, confluence / priority, load retention
MO170/280EX performance improvement: the system pressure increases, the bucket oil regeneration control changes, optimize the rotary logic valve, bucket stroke limit.
MO400EX performance improvement: Based on the input pressure proportional flow control, the external spool form regeneration function, increase the use of flow, two seat valve form to maintain the valve - low leakage.
Load sensitive system (3~8Ton)
Advantages of load sensing system (graph)
The advantages of load sensing system
Load sensitive pressure compensated main valve VP120 features: after valve compensation flow sharing, global design ideas, global manufacturing strategy, general components.
Paving functional products
Paving function valve features: oil path selection, load retaining valve, pilot oil buffer valve. Auxiliary valve plate, stack valve / combination valve
Two, Parker excavator application of new technology
IMV independent control main valve
What is IMV?
Based on the flow amplification valve technology, according to the application and other needs, can flexibly adopt different structures to meet the needs of the future energy saving design, fully integrated Parker electronic and control technology
IMV200 technical parameters: valve flow: 200L/min, maximum pressure: 350 bar, back pressure: 25 bar (ratio), oil port thread: BSP, UNF
Customer benefits: reduce throttling loss, oil regeneration, can recover potential energy in pump control or electro hydraulic hybrid system, automatically select the best energy saving mode, soft mode switch.
Rotary energy recovery system
The advantages of hybrid rotary systems: 1. Energy recovery - hybrid rotary systems capture the energy generated by rotary braking and store them in accumulators, and then release these energies during rotational acceleration. 2, engine assistance - the stored energy can be used to balance the engine power, so that the engine is running in a more optimized state. 3, Productivity Promotion - synchronous control can improve the function of the machine and the total production capacity.
Field test results: 1, fuel consumption is reduced by 50% in single turn action, 25% in compound action, 2 in braking, energy recovery and conversion to achieve accurate rotary control and stable rotary drive. 3, based on the lifting of the rotation control, 10% of production capacity can be improved.
Why choose Parker?
