Pro-Mix V Dual DC Lubricating System

SPECIFICATIONS

The PRO-MIX Lubricating System is manufactured to thoroughly mix lubricant concentrate with water to the desired mixture, and distribute the mixture to each press through an in-plant piping network. Each press coupled to the network will receive a continuous ,supply of pressurized lubricant. Additionally, the machinery can be manufactured to supply TWO or THREE different mixtures of the lubricant concentrate to each press. The following proposal defines the FUNCTION, SYSTEM COMPONENTS, SAFETY FEATURES, and COST of the machinery.

SYSTEM COMPONENTS

Dual Stainless Steel Liquid Reservoirs (Water and Lube Concentrate) used to stabilize the liquids prior to mixing. Support systems of the reservoirs include: Automatic Liquid Refill Systems (Pump/Valve Assembly).
Fluid Level Supervisory System. Fluid level monitors located within the system reservoirs continuously monitor the level of the two materials. These monitors are used to refill the reservoirs on demand and to discontinue the machine's service if a dangerous low material level develops during the system's operation.
Patented PRO-DRIVE Assembly used to thoroughly mix, control, and pressurize if necessary, the mixture. Components include: Vari-Drive Transmission, Drive Motor, Pump Network, and Mixture Transducer. The number of identical PRO-DRIVE assemblies is determined by the number of different mixtures required (TWO or THREE).
Mixture Ratio Display that displays, an the machine cycles, the mixture being produced by the machine. The display will additionally total the volume used during a user selectable period. Each mixing station has an independent Mixture Ratio Display dedicated to that specific station.
Electrical and Electronic Package used for system control and process monitoring - Components include: Support Electrical Apparatus, System PLC, Mixture Display, and Operators Interface.
System ALARM and Diagnostic Indicators. The system includes an Audible/Visual Alarm that activates if a system problem develops, and process diagnostic Indicators that identify the problem area.

MIXTURE RATIO DISPLAY
The MIXTURE RATIO is displayed in whole numbers that represents- the mixture being produced as the Lubricating System cycles. EXAMPLE: A mixture of 5/1 would be displayed as 5.0. Any change in the mixture ratio would reflect a change in the display. An the mixing cycle has completed the display will LOCK IN the mixture value. The display is coupled to a flow transducer that accurately measures the flow of the WATER in the mixture. Because the PRO-MIX V varies only the amount of water in the mixture and mixture changes are made by INCREASING or DECREASING the amount of water only, the displayed value can be held within +/- 1%. Additionally, the display will total the amount of mixture produced over a period of time in gallons. This value is selective and can be reset as required. Because the MIXTURE DISPLAY is manufactured to comply with a variety of applications by Red Lion Controls, additional benefits may be realized. As a standard option the display includes a RS-485 communication loop which can interface with a standard computer system. Pertinent information such as RATIO/VOLUME/TIME/DATES can be transmitted to the computer each cycle of the machine and archived for future reference.

SAFETY FEATURES SUPPORTED BY ACCURATE METERING SYSTEMS

Low Liquid Level Sensors that will discontinue the machine's service if a DANGEROUS Low Level is detected in the system's Water or Lube Concentrate reservoir.
INDEPENDENT High Pressure Supervision that will discontinue the machine's service if a DANGEROUS High Pressure is detected within the mixed material delivery network.
INDEPENDENT Mechanical Pressure Relief that will relieve the pressure within the system's delivery network if the high pressure switch fails.
INDEPENDENT Piping Network Supervision that will discontinue the machine's service if a broken line in the delivery piping system is detected.
Lube Concentrate Supply Supervision that will alert the system's operator to a supply out condition. The Lube Concentrate Supply Empty Alarm will NOT discontinue the machine's service.
INDEPENDENT Mixture Testing Device that allows the operator to perform mechanical mixture tests. This system provides an accurate real time testing of the mixture.
Audible/Visual Alarm System consisting of a RED flashing strobe light and horn that activates if a process problem develops.
Diagnostic Indicators used to identify a process problem if one occurs. The indicator display also identifies a low lube concentrate supply container.

UNIQUE CHARACTERISTICS

MIXTURE TESTING FEATURE. The Mixture Testing function is used to mechanically test the mixture being produced by the machine. The test takes only minutes to perform and does not require the machine to be taken OFF-LINE.
All of the machine functions are controlled and monitored by system's Allen Bradley PLC.
ONLY the AMOUNT of WATER can be varied in the mixture. Greater process control is attained through the utmost in mixture stability.
Mechanical coupling of the TWO system pumps for absolute MIXTURE CONTROL.
ONE 3/PHASE 1.5 HP INDUSTRIAL MOTOR controls all of the machine's mixing functions (EACH Station).
Through a simple modification the PRO-MIX can be adapted to a variety of mixture ranges.
Diagnostic Displays - Alarm System - Mixture Ratio Mixture Totals (EACH Station).

As stated, the number of different mixtures a lubricating system can produce is dependent upon the number of mixing stations. The following is a list of mixture ranges. Any combination of lubricant mixtures can be selected.

MIXTURE RATIO RANGES DEFINED AS WATER 10 TO LUBE 1 = (10/1)

(A) 1/1 to 3/1 The preferred method of choosing mixture
(B) 3/1 to 10/1 ratio range is determining the mixture you
(C) 6/1 to 20/1 require and choosing the range that will
(D) 10/1 to 30/1 produce the mixture at 50% of scale.
(E) 20/1 to 60/1 EXAMPLE: Required Ration = 40 to 1

OPTION: Certain lubricant concentrates (NON-Synthetic) change viscosity's due to temperature (HOT=Thin / COLD=ThIck). if these type of lubricants are used consistent metering of the material with our positive displacement pumps can be difficult. The consistency of the mixture is proportional to the control of the materials mixed; therefore, if the lubricant concentrate's viscosity varies so will the mixture. In order to maintain a consistent mixture the lubricant concentrate must be stabilized by heating the material to a controlled temperature. SPRA-RITE's optional heating system includes a 3-Phase industrial heater placed in the water reservoir and a I inch copper tubing network in the lubricant concentrate reservoir. By means of thermodynamics the heated water is pumped through the piping network heating the lubricant concentrate. This indirect heating will stabilize the lubricant without damage caused by direct heating. The materials temperature is controlled by a thermostat located within the heating element. Additional LOW WATER level protection is provided by the PLC, water level sensor, and a disconnect relay.

If you are unsure of the lubricants characteristics with regards to temperature place a sample (cup) in a refrigerator for two hours and compare with the original.
