Hydraulic machine of maintenance - Mixer epicycloidal

DESCRIPTION

The hydraulic mixer epicycloidal is an hydraulic machine making it possible to carry out the hydraulic maintenance of system to hydrostatic transmission

Support for adjustments activities, diagnosis, replacement of failing hydraulic components and improvement of the system

Machine being able to be used only or joined with crusher MMH 101 and MMH 103

The machine is delivered supplements, instrumented, with technical handbook and practical work.

Teaching equipment : Hydraulic machine of maintenance - Mixer epicycloidal - MMH 102

Material of industrial type.

Teaching concerned: Maintenance of the industrial systems and complementary mentions in hydraulics

Technical description and activities of maintenance on mixer:

Structure
- Aluminum Frame anodized on wheels with brake section 90 * 45mm
- Structure of the system of sheet steel mixer/assemblies screwed and welded
- Supplements with protected openings coupled to security chains of the machine
- Cylindrical Hopper with horizontal axis of capacity 500L approximately

Mechanical description of the system of malaxation
- Gravitating Food of the broyat
- 2 rotors equipped with blades
- system with planetary movement/standard epicyclic gear
- 2 trees ensuring guidance in rotation of the rotors
- gone up together on 2 concentric plates guided in rotation by ball bearings
- hopper acting as reserve of 500L approximately, dynamic accumulation for control of the management of flows

Mechanical description of the evacuation of the broyats
- 1 rotor equipped with a Archimedes' screw located along a generator of the hopper and allowing to evacuate the totality of the volume of broyat contained in the hopper
- device of coupling to press MMH 103 or a vat of substitution
- transmission of power by chains and pinions.

Sensors:
- Pressure gauge pressure controller for detection of surpession and blocking of the mixer
- 2 inductive Sensors for velocity measurement of rotation of the crusher
- module and detection velocity measurement of direction of rotation

Supervision (option):
- visualization of the state of the pre-actuators
- representation by diagrammatic hydraulics and emulation of magelis posting
- complete piloting/started/put moving of the machine
- reading of instantaneous measurements number of revolutions

Electric structure:
- general disconnecting switch of power supply
- standard module of safety PREVENTA coupled with the sensors of safety and emergency stop
- circuit breaker and differentials for protection
- piloting of the machine since the button manufacture located on the box
- posting number of revolutions on desk
- piloting, parameter setting and assistance with the diagnosis by standard IHM magelis
- Schneider automat with analogical chart
- control speed per automat
- possibility of substituting this direct order by order since supervision/connection on standard connector sub D for locking on box (RS485)

Description of the hydraulic components in initial version:
- 1 power station with engine 5,5 kw/all hydraulic components of the power station apparent
- tank of 100L
- 1 pump with variable cubic capacity 12cm3/hand drive operation of flow + direction of walk (for mixer)
- 1 pump of cramming 4cm3 approximately integrated into the principal pump
- 1 hydraulic engine on mixer
- group of sweeping (hydraulically-operated distributer 3/3 closed center)
- valves anti return on system of cramming
- 1 pump on engine 0,75kW for pilot circuit of the flow
- 1 hydraulic actuating cylinder race 150mm gone up on lever for integration of an hydraulic function of piloting of the flow
- 1 distributer 4/3 for piloting of the jack

Activities for functioning crusher only or in line (any defective or replacement material are provided)
- Integration of a whole of components (distributer, jack and flexible devices) to carry out malaxation uninterrupted as well as the controlled piloting number of revolutions of the mixer in the 2 directions of walk.
- Replacement of failing distributer 4/3)
- Integration and/or adjustment of the flow controls valve allowing to stabilize the control the speed of the mixer

PEDAGOGIC APPLICATIONS

- Adjustment of the hydraulic components
- For obtaining the nominal conditions of walk of the machine.
- Diagnosis and replacement of hydraulic and electrohydraulic components failing
- Implementation of measures of the characteristics flow and pressure for activities of adjustment and diagnosis
- Modification of the hydraulic installation for improvement of the operation of the machine

UTILITIES
Electricity: 400 VAC will tetra/20 A mini - 50Hz

VOLUME Of INSTALLATION
WRAPS NET (Lxlxh in mm): 2200x1100x1900

Weight 500kg
