Drilling mud pump, which abbreviation name is mud pump, is the heart of oil well drilling. It is one of the most important drilling equipments. Its main function is circulating mud during drilling operation. On the base of series F mud pump technology, Shengli General Machinery Plant designed series of FS mud pump. After studying the advantages of horizontal triple-action pumps both home and abroad, the plant optimized the pump's structure and specification. With advanced structure, the performance of Series FS mud pump is much better than series F mud pump.
Features of Series FS mud pump:
(1)With compact structure, better load capacity, high reliability, low noise, triple-action drilling mud pump can easily meet therequirements of drilling technology such as high pump pressure and big fluid volume.
(2) With long stroke length and low stroke frequency, the pump reduces the pipeline's fluid pulsation, prolongs the lifespan ofhydraulic wearing parts and increases water-lifting capacity efficiency.
(3)Cylindrical roller bearings install on both ends of the shaft (which integrated with pinion gear). There are keyways on bothextended shaft ends, which can install belt pulley or chain wheel.
(4) The reliable suction stabilizer is well designed. It not only acts as a cushion for the suction pipe, but also avoids high pressuredestroying the pump (pressure safety valve installed on the stabilizer).
(5)Important parts such as hydraulic cylinder, crankshaft, herringbone gear(without escape) are made of high quality alloysteel. The welded frame has the advantages as high strength, fine rigidity and light weight, etc.
(6)The perfect lubricating system is composed of gear oil pump and pipes. It provides lubricant to the moving parts of powersection and piston.
(7)The pump is mainly composed of power section and hydraulic section. All the consumable parts are standardized, whichhave good interchange ability.
