Hydraulic cylinder is the main component and important accessories of oil drilling rig mud pump. It belongs to the hydraulic end part. It is a high precision high pressure valve. Its function is mainly used for the suction and discharge of mud pump at the hydraulic end of mud pump.
The slurry pump cylinder produced by our company is made of high quality alloy steel forgings with corrosion resistance and high strength. After quenching and tempering, it has the characteristics of tensile resistance and wear resistance. At the same time, the domestic leading XH768 NC machining equipment and technology, which integrates drilling, milling and tapping, are adopted in the internal cavity processing, so that the valve box can withstand 31MPa working pressure. It improves the machining precision and safety factor of the valve box, and makes the valve box have the advantages of high pressure and corrosion resistance, long service life, etc. It is more suitable for drilling technology requirements such as high pump pressure and large displacement. The product conforms to API SPEC 7K specification and is widely used in oil drilling industry. This product not only sells well to all major oil fields in China, but also exports to the United States, the Middle East and other international markets. Besides, we can also produce other kinds of valve boxes according to the customers' drawings and requirements.
The material of liquid cylinder is alloy steel 35CrMo or 40CrMnMo forgings, and three liquid cylinders of each pump can be interchanged. The structural design of straight through type liquid cylinder or valve upper valve of F pump reduces the volume of liquid cylinder and improves volumetric efficiency. If the user requests, the surface of the liquid cylinder can be treated by electroless nickel plating to enhance its corrosion resistance.
