Product Description

Mud Pump Spare Parts supplier -Dezhou Changhong Machinery Manufacture Co., Ltd We supply Mud Pump spare parts like mud pump liner( including zirconia ceramic liner and high chrome bimetal liner), mono-metal Liner, Fluid End Module, valve and seats, piston, piston rod, pony rod etc. parts for mud pump, we can also customize and machine as your drawing.     High chrome bimetal liner: Application: High chrome bimetal liner is used as a kind of mud pump fluid end accessories in the oil drilling industry. Features: Our bimetal liner, API certified, providing wear-resistant outer sleeve and high chrome corrosion-resistant inner sleeve. The high chrome liner has high rigidity of HRC>65 after heat treatment. Advantages: The bimetal liner offers long service life of about 800 hours, which is 2 to 3 times the lifetime of common ones in severe environment.Dezhou Changhong is a professional Chinese bimetal liner manufacturer, with more than 20 years manufacturing experience. Through our consistent effort, we are able to manufacture high quality mud pump parts, valve, drill rig, and other products. Due to reliable performance and long lifetime, our products are well accepted by global customers. If you require more information about our oil equipment, please feel free to contact us.    Zirconia Ceramic liner * Suitable for deeper oil reservoir,bad drilling geological structure environment,offshore oil and gas development. *Service time is 5-10 times than bi-metal liners.The using time of liners are up to 6,000 hours. *The material of ceramic liners is the increased flexible zirconium ceramic.These liners feature wear resistance,high anti-corrosion,high temperature resistance,high pressure,high intensity and high hardness. *Reduced the freight cost,maintenance cost,labor cost and storage cost of oil drilling. *Zirconium ceramic liners have better performance than alumina ceramic liners such as more toughness,longer service life,saving water lubrication,reducing wear of piston.

Heat treatment process adopts carburizing quenching furnace controlled by advanced microcomputer. The carburized layer of Body, seat of is between 1.8 ~ 2.2 mm. The hardness of 55°cone valve body and valve seat after quenching hardness is up to HRC60.Because all the geometry size of finished product processed by CNC machine, so to ensure and improve the performance of the valve body and valve seat sealing.   Our company can produce the API 5 # ~ 9 # styles of full-open valve body ,seat and double support body, seat.Products has the advantage of large displacement, the seat is convenient.Because it is equipped with high strength of polyurethane rubber valve, so in the process of using the valve body and valve seat had higher strength and longevity. The use time of our company products is 4 ~ 5 times that others can be used more than 340 hours  Piston assembly   Piston assembly is the expendable parts at the drilling pump hydraulic system,and its  one of the biggest wearing parts of drilling work.The piston core is made of 42CrMo.Our company can produce F series,3NB series,9-P-100/13-P-130/12-P-160 series,PZ7/8/9 series of drilling pump piston assembly metric(inch) with various sizes.   The piston rubber is also called the piston cup,its the expendable parts at the drilling pump hydraulic system,and its one of the biggest wearing parts of drilling work.The piston rubber is made of rubber vulcanization.The material of ordinary piston rubber is NBR. But if you use the PU can enlarge the work temperature range. Fluid end module     Module belongs to hydraulic end, which is important component of mud pump. It is a kind of anti-pressure valve and mainly responsible for sucking and discharging mud in hydraulic end. We selected anti-corrosion and high strength superior forging big alloy pieces as material, it possess high tensile and anti-wearing after quenching and tempering. We have applied drilling milling & tapping craft by XH768 CNC Machining Equipment which improves machining precision & safety factor. It makes the module can bear 31MPa working pressure and possess anti-high pressure, anti-corrosion & long life time, which is more suitable for strict requirement of oil drilling. Our module are completely meets API SPECT 7K Standard. It is widely used in oil drilling industry. The material of module is forged 35CrMo or 40CrMnMo pieces. Three modules of each pump are interchangeable. The through way F type pump namely valve coupling with valve structure, have lessen the volume of module and improved cubage. For improving anti-corrosion, We can nickelizing on module surface as per customer’s requirement.    Piston rod and pony rod      Applications Piston rod, as a kind of Mud Pump Parts, is used as a fluid end accessory in the oil drilling industry. Features  The piston rod is made of structural alloy steel, which goes through tempering heat treatment to achieve superior mechanical performance. The surface of the piston rod can be treated through phosphatization or galvanization.
