INTRODUCTION Figure 1-2 ACD-1500 Degasser Functional Diagram 15 Apr 11 1-3 ACD-1500Degasser
INTRODUCTION MAJOR COMPONENTS The degasser (Figure 1-3) consists of a spray tank, electric motor-driven centrifugal pump, impact plate, electrical control panel (optional), vent, and exhaust blower. These components are described in the following paragraphs. Spray Tank Fluid dispersed at high velocity by the impact plate spreads across the interior surfaces of the spray tank. The tank’s shape encourages release of entrained gas from the mud.

SECTION 2 - SAFETY INTRODUCTION This section contains a summary of WARNINGS used in this manual and a list of material safety data sheets (MSDSs) applicable to the equipment. The ACD-1500 Degasser has been designed to perform the stated functions safely. WARNINGS All persons responsible for operation and maintenance of this equipment must read and understand all safety information in this manual prior to operating and/or maintaining the equipment.
SAFETY Equipment Handling WARNING! TO ENSURE PROPER BALANCE AND ORIENTATION WHEN UNIT IS RAISED AND PREVENT DAMAGE TO COMPONENTS, ATTACH LIFTING SLINGS ONLY TO LABELLED LIFTING POINTS. DO NOT ATTEMPT LIFTING BY ATTACHMENT TO ANY OTHER LOCATION. WARNING! BE SURE THAT HANDLING DEVICES HAVE SUFFICIENT LIFTING CAPACITY TO SAFELY HANDLE THE WEIGHT OF THE EQUIPMENT.
SECTION 3 - INSTALLATION GENERAL This section describes the recommended installation procedure for the ACD-1500 Degasser. Instructions include equipment handling, equipment leveling, and electrical connections. SAFETY Read and understand ALL safety information presented in this manual before installing and operating this equipment. Refer to Section 2 for a summary of Warnings affecting installation, operation, and maintenance of this equipment.
INSTALLATION STORAGE Storage Before Use If equipment is not being installed immediately, it should be stored in a dry environment (50 percent relative humidity or less). A dry environment will ensure that the machine remains in the same condition as when it was received. If unit is stored outdoors, use a UV-resistant tarp, or UV-resistant shrink wrap. Install vents when using shrink wrap. Seal the Operation and Maintenance manual in plastic and attach to unit.
INSTALLATION WARNING! BE SURE THAT HANDLING DEVICES HAVE SUFFICIENT LIFTING CAPACITY TO SAFELY HANDLE THE WEIGHT OF THE EQUIPMENT. WARNING! WHEN USING AN OVERHEAD LIFTING DEVICE, USE ONLY THE LIFTING LUGS PROVIDED. DO NOT ATTEMPT TO LIFT MACHINE USING ANY OTHER LIFTING LOCATION. Equipment Hoisting Two lifting lugs are attached to the degasser to allow attachment of an overhead lifting device (Figure 3-1). The lugs are labeled “LIFT HERE ONLY”.
INSTALLATION Positioning and Mounting Position the degasser with sufficient space around unit to allow access to various components by operators and maintenance personnel. Approximately 2’ to 3’ (610mm to 914mm) space is required on all four sides of the equipment. The recommended installation is to weld rails close to the degasser to “trap” the machine in place. The degasser should not be welded to the tank as this installation will prevent access to the pump.
INSTALLATION VENT LINE AND DISCHARGE DUCT Vent Line 1. Connect a 4-1/2” (114mm) ID vent line to the exhaust fan outlet. The vent line flange must have a four-bolt 8-1/2” (38mm) diameter pattern. The vent line must be long enough to convey the discharged gas to a safe area. 2. The vent line should be supported independently. Any elbows should be located at least two fan wheel diameters from the exhaust fan.
INSTALLATION ELECTRIC POWER CONNECTIONS (CONT’D) 2. Install starter box, if required for the installation. 3. If degasser is equipped with a Derrick-supplied electrical control panel, pass three-phase cable through conduit and into the control panel, and connect to terminal block or contactor. 4. Connect three-phase power leads inside the control panel (Figure 3-4), or as required for customer-supplied starter box or other supply source. 5.
INSTALLATION Figure 3-5 Impact Plate Adjustment MACHINE STARTUP Refer to Section 4 for startup and operating procedures.
SECTION 4 - OPERATING INSTRUCTIONS GENERAL This section includes initial and normal startup shutdown procedures for the ACD-1500 Degasser, as well as emergency shutdown. OPERATING SAFETY WARNING! ALL OPERATING AND MAINTENANCE PERSONNEL MUST READ AND UNDERSTAND ALL SAFETY INFORMATION IN THIS MANUAL BEFORE WORKING WITH THE EQUIPMENT.
OPERATING INSTRUCTIONS NORMAL SHUTDOWN The normal shutdown procedure is to be used for controlled stopping of operation. Normal shutdown is performed for routine activities such as cleaning, lubrication, inspection, or other routine procedure. 1. Shut down electric power to stop the centrifugal pump and exhaust fan. 2. Open fused disconnect that supplies electric power to the machine.
SECTION 5 - MAINTENANCE GENERAL Proper maintenance will ensure maximum life and trouble-free operation. While the maintenance schedule presented in this section is not rigid, modifications should be based on experience with operating the equipment at your facilities. A maintenance log should be kept to help establish a routine maintenance schedule, as well as to monitor and adjust the schedule as necessary throughout the equipment’s life.
MAINTENANCE BEARING LUBRICATION (CONT’D) The recommended lubricant for the shaft bearings is NLGI grade 2 mineral oil lithium or lithium complex base grease. Grease should be injected into grease fitting until purged through the fitting regardless of the quantity added.
MAINTENANCE ACD-1500 DEGASSER TROUBLESHOOTING Trouble Low flow rate through degasser Excessive noise and/or vibration Possible Cause Remedy Impact plate not adjusted correctly Increase clearance between impact plate and riser. Low fluid level Check that fluid level in tank is above pump bolting flange. Raise level if necessary. Worn pump Inspect centrifugal pump for wear. Repair or replace pump as needed. Inlet opening partially blocked Turn off unit.
MAINTENANCE SPARE PARTS The following table lists the recommended spare parts to support one ACD-1500 degasser for two years. However, since all potential part replacements cannot be predicted, the complete spare parts inventory should be based on the user’s experience with similar equipment. When establishing a spare parts inventory, consider the equipment’s duty cycle and operating environment. RECOMMENDED SPARE PARTS - ACD-1500 DEGASSER Part No.
SECTION 8 - REFERENCE DRAWINGS This section contains Derrick engineering drawings for your equipment. These drawings are included to provide assistance in troubleshooting, repair, and parts ordering.
SECTION 9 - INSTALLATION AND MAINTENANCE LOG PURPOSE This section should be used by operating and maintenance personnel to record historical information gathered during the installation and operation of the Derrick equipment. If properly kept, the log will be useful for altering maintenance intervals and intercepting trends that may indicate the need for changing operating procedures. Each entry in the log should be dated for future reference and tracking.
