Oil Drilling Motor Pump

oil Drilling Motor Pump It is one of the essential equipment for oil drilling rigs and mud purification systems. It belongs to a single-stage single-suction high-efficiency energy-saving type pump, used for the circulation solid control system of oilfield drilling rigs and engineering drilling. It conveys drilling fluid containing solid particles to devices such as sand separators, mud separators, and mixer. This equipment is composed of components such as pump casing, impeller, pump shaft, sealing device, bearing seat, coupling, motor, and base. Manufacturers such as Xi'an Henglian Petroleum Equipment Co., Ltd. produce models including SB8×6-55kw and SB5×4-22kw, which can be adapted to various solid control equipment and working conditions. It adopts an open impeller design to adapt to high-viscosity media. The impeller is connected to the pump shaft by threads and is equipped with a locking nut. The sealing device includes components such as mechanical seals and packing. The new design forms an air barrier through vortex theory to separate the mud from the shaft seal, solving the problems of shaft seal leakage and short lifespan. This technology has obtained a national utility model patent (patent number: ZL200420105829X). The pump body is optimized in design, and components such as the bearing seat and shaft are designed with a self-aligning bearing and a rear bearing group combination. During maintenance, the impeller can be axially pulled out and replaced with a soft seal by adjusting the bolts.

oil Drilling Motor Pump It is a type of centrifugal mud pump, used for transporting suspensions containing sand particles, slag, etc. The impeller is mostly open. The inner lining of the pump is generally divided into two types: wear-resistant metal and wear-resistant rubber. Additionally, high-pressure water is injected into the sliding parts of the pump shaft to prevent sand and silt from entering the sliding parts. This pump can be used for the transportation of liquids containing coarse solid substances with particle sizes above 48 mesh. The sand pump is merely a specific application of the centrifugal pump and is named so. Essentially, the sand pump is just a general term. Generally, it is mainly used in industries such as mining, coal, metallurgy, chemical industry, and environmental protection. In a general sense, the sand pump is more commonly used in industries such as environmental protection, sand excavation, and river dredging.

I. Usage and Scope of Application
The SB series centrifugal sand pump is mainly used to provide support for the circulation solid control system of oilfield drilling rigs. Its function is to supply drilling fluid with a certain flow rate and pressure to the sand separators, mud separators, mixing devices, etc., in order to ensure the efficient operation of these equipment.
Among them, the SB10×8×14 centrifugal sand pump is mainly suitable for drilling rigs with a depth of over 3000 meters, and is used in drilling projects where the drilling fluid viscosity and specific gravity are relatively high; the SB8×6×14 centrifugal sand pump is mainly used for drilling rigs with a depth of over 3000 meters; the SB8×6×11 centrifugal sand pump is mainly used for drilling rigs with a depth of below 3000 meters, and can also be used as a pump to supply fluid to the three-cylinder mud pump; the SB6×5×11 and SB5×4×14 centrifugal sand pumps are generally used for the matching of truck-mounted drilling rigs or small drilling rigs; the SB4×3×13 centrifugal sand pump is matched with the metering tank and is usually called a metering pump or a replenishment pump; the SB3×2×13 centrifugal sand pump is generally used as a water pump.
II. Structural Characteristics
The features of this series of centrifugal sand pumps are:
It can be interchanged with the American MISION pump. All the accessories can also be interchanged with the American MISION products. The manufacturing standards are also based on those of the MISION pump. Therefore, it has a broad sales market in the international market.
2. The series of sand pumps consist of 8 types of pumps, which are suitable for the matching of the entire solid control equipment. The bearings, shafts and other components in the series of sand pumps are common, making spare parts and maintenance convenient and reducing costs.
3. Open-type impeller, suitable for transporting high-viscosity drilling fluids;
4. A combination of mechanical seal and packing seal is adopted, which ensures excellent sealing performance and long service life.
5. The main components (pump casing, impeller, mechanical seal box) are all made of wear-resistant ductile iron QT600-3, which are precisely cast using resin sand technology. They have a long service life and a beautiful appearance.
