1.3 OVERALL CHECK OF THE MIXING UNIT
Before you can start mixing there are a several checks to be made:
1. Check for debris in the mixing tank
2. Put 2 pump strokes of high quality bearing grease in all nipples on the GORMAN RUPP pumps.
3. Check if all electrical cables and wires are still in good condition, repair if necessary.
4. Check, overall, for any damaged or loose parts and repair if needed.
5. Check all guards.
6. Check the tank for cracks.
1.4 CAPACITY PARAMETERS
This unit is capable of mixing 250 ltr/min with normal fresh water, 7 ph and up to 60 sec of viscosity.
2.1 CHECK BEFORE STARTING THE MIXING UNIT
Before starting the unit you must do a quick check of all components of the unit:
1. Check the pump: - fluid levels
- debris plugging suction
2. Open suction valve and close drain valve
2.2 STARTING THE MIXING UNIT
First make your self acquainted with the valve schedule in 5.3.
1. To start the mixing unit, fill the complete unit for 3/4 with water.
2. Open suction valve mix pump from mix tank nr.1.
3. Close the air bleed valve on the impeller housing of the mixing pump when all air is out of the pump.
4. Open the discharge valve from pump to venturi nr.2
5. Start diesel engine
6. Now you can start mixing bentonite with the unit: open the valve of the hopper approx. half way.
7. Now suction noise will be heard out of the hopper funnel. Slowly add bentonite.
8. Add bentonite until required mud-viscosity is reached.
9. Open discharge valve to nozzles.
10. Run the unit for a few minutes: keep in mind that the viscosity of the mud will increase in this time as the mud is
being sheared
As mud is being used the fluid level inside the mixing tank must be maintained: add water and bentonite on time and, if a
mud recycling system is used, keep a eye on the mud level of the mud pit, with a SiteTec recycling system, mud will be
transferred from the recycling unit to the mixing unit. This means you have to add very little bentonite and/or water, just to
keep the mud level in the mixing tank to its maximum and in the right condition.
