Motors in solids control are the motors on solids control equipment. Including vibrator motor on shaker, decanter centrifuge motor, centrifugal pumps motor
We call shale shaker motors as vibrator motor. Shale shaker motors are generally three-phase induction motors that are explosion proof, having NEMA design B or similar characteristics. The number of magnetic poles in a shale shaker motor can be four (1800 rpm synchronous shaft speed at 60 Hz), six (1200 rpm), or two (3600 rpm). But four poles are most popular among solids control system The motor should have independent, third-party markings indicating its suitability in explosive or potentially explosive environments. It is recommended that these motors be suitable for Class I, Division 1, Groups C and D, and Group IIB atmospheres. The motor also should have the proper operating temperature or code designation for the anticipated ambient temperature.
Shale shaker motors different installation way and different size will reflect different vibration mode. such as the linear motion, circle motion, balanced elliptical motion, and so on. The internal wedge block place vary will control vibration strength
Most centrifuges use the explosion-proof motors used for centrifugal pumps: either 1500 rpm at 50 Hz or 1800 rpm at 60 Hz. Centrifuges may draw up to seven times the full-load current for approximately 15 seconds at startup. It is considered good practice to limit centrifuge startups to two starts per hour to protect the motor because the current draw closely approaches the limit.
Oilfield centrifuges do not always use a direct drive between the motor and centrifuge. Direct drive requires expensive, variable-speed motors that have restricted availability of replacement parts and repair facilities Most oilfield centrifuges are connected to the motor by a fluid clutch or a hydraulic drive, which uses a system of adding or subtracting motor or hydraulic oil to increase/decrease slippage between the driver and driven coupling halves. Some oilfield centrifuges use a variable-speed electric motor startup system that brings the centrifuge slowly up to operational rotating speed. It is important that all personnel understand the manufacturer’s recommended startup and shutdown procedures.
Solids control centrifuges are fit with 2 motor. One is main motor another is back driver motor. They are both connected with reducer and main centrifuge drum also conveyor.
Centrifugal pump is also referred to sand pump in solids control system. All oilfield equipment motors and electrical parts should be explosion proof. Centrifugal pump motors, centrifuge motors, and agitator motors are all same. Centrifugal pumps should be sized by the particular application and the maximum anticipated flow rate. Piping friction losses—if lines are reasonably short, with few turns or restrictions, and flow velocities between 5 and 10 feet per second—are readily estimated. The pressureor head, which should be delivered to each piece of equipment (for hydrocyclones, typically 75 feet of head) is specified by the equipment manufacturer.
Horsepower requirements for centrifugal pumps, when pumping water or fluids of water-like viscosity, are well established and published with the performance curve for each design.
