The mud pump module cylinder material is made of high quality alloy steel forgings, and the three cylinders of each pump can be interchanged.Straight through type hydraulic cylinder namely the valve on the valve structure design, reduced the liquid cylinder volume, raised the volume efficiency. Heat treatment and internal hardening treatment for high durability products; The process has been strictly inspected and strictly tested.
The valve box is designed to meet the standard of pressure of 5000, 7,500 and 10000psi (pound) (351,527 and 703kg/cm2), and the process is completed by numerical control, and the product quality is guaranteed. In order to obtain better fibrous tissue, we use electric furnace for secondary smelting or deoxygenation treatment. Forging parts are forged from three directions, with a forging ratio of 3. During the forging process, there are no defects such as interlayer, crack, impurity, loose, overburning, etc., and no welding. The forging is completely in accordance with JB4730-94 standard for processing and forging, and it is reported to national standard GBT6402-91 inspection standard. After normalizing, rough machining was carried out, and the hardness of the inner wall was up to HB285-330. Mechanical performance: σb≥850MPa，σS≥670MPa，δ≥5%，ψ≥30%. The contact surface of the two parts with 1:6 (1:12) cone holes shall be continuously distributed on the circumference with no less than 75% contact area. The intersecting line of each cylinder in the inner cavity is formed into arc R≥8 by using the inverted obtuse Angle of manual or grinding wheel. Pressure test is 49Mpa, and the pressure is kept for 1 hour.
In order to better serve the customer and guarantee the interests of the customer, we can issue the national level II inspection report according to the customer's requirements. Improve service quality to achieve "service first, credit first, quality first" business philosophy.
