IDECO MM-550-F Pump

Power end - the strong heart that drives the operation

Framework and structure: the cornerstone of durability

Materials and processes: The rack of MM-550-F adopts Welded by high-strength steel plate , instead of the traditional cast iron structure ^.After the welding is completed, the whole rack will undergo strictPost-welding stress elimination heat treatment.

Transmission system: the fusion of precision and power

Crankshaft: Use All-in-one forged alloy steel crankshaft ^.

Gears: The core of power transmission is Herring-shaped gears Designed large gear rings and small gears. All gears are precision-machined from forged alloy steel blanks and heat-treated to obtain hard and wear-resistant tooth surface and strong tooth core. ^.

Bearing configuration: We only use top brands of heavy-duty roller bearings to provide the most reliable support for each rotating part:

Main bearing: Double-row tapered roller bearings or concentric roller bearings are used.

Small gear shaft bearing: Using a spherical roller bearing, its self-aligning characteristics can compensate for the small bending deformation of the shaft under heavy load, ensuring that the bearing is always in the best working state, thus extending the service life.

Connecting rod and cross-head bearing: Choose cylindrical roller bearings and needle roller bearings with high bearing capacity specially designed for high-load reciprocing motion ^.

Reciprocal motion assembly: lasting linear dynamics

Cross head and guide plate: The cross head body adopts integrated cast steel parts to ensure the highest strength and rigidity.The core highlight of its design is the adoption of Replaceable bronze guide plate ^.

Connecting rod: Made of high-strength forged steel, its joint structure ensures maximum strength under severe loads.

Lubrication system: the lifeline of the power end

Compulsory lubrication: The built-in gear oil pump actively delivers the filtered lubricating oil to the key friction vices such as the main bearing, connecting rod bearing and crosshead, ensuring sufficient oil film protection at any speed. ^.

Splash lubrication:The rotation of the crankshaft and the large gear ring will stir up the lubricating oil in the oil tank, forming a continuous oil mist and oil bath, providing lubrication for the gear engagement surface and other parts, forming a set of simple and effective redundancy protection mechanisms. ^.

The superiority of manufacturing technology:Each hydraulic end module is made of a whole piece of high-quality alloy steel billet, which is repeatedly forged and molded under a pressure of thousands of tons.

Strict quality assurance: After forging, each module must undergo multi-stage heat treatment and internal quenching process to obtain the ideal hardness and toughness match. Then, we will adopt the mostStrict non-destructive testing (NDT) technology, such as ultrasonic flaw detection, comprehensive internal and external inspection to ensure that the module interior is absolutely pure and free of any inclusions or microcracks. `

We have carefully selected the top-notch for the hydraulic terminal module.High-strength alloy steel, such as 35CrMo or 40CrMnMo .

Designed for high pressure and convenient maintenance

Pressure level: The hydraulic end of MM-550-F is designed for up to 5,000 psi (34.5 MPa) The pressure ofContinuous work under force, and can meet the needs of higher pressure through specific configurations, fully covering the pressure requirements of the vast majority of medium and deep well drilling operations.

Valve-Over-Valve structure: We adopt an advanced valve-on-valve design, that is, the suction valve and discharge valve are arranged vertically. This structure can minimize the residual volume of the cylinder, thus significantly improving the volumetric efficiency and overall hydraulic performance of the pump, so that more effective fluid can be delivered per stroke.

Maintainability design: We are well aware that time is money at the drilling site. Therefore, the hydraulic end is equipped with Quick-change valve coverAndThreaded cylinder liner pressure coverThe design makes the operation of replacing consumable parts such as valves, valve seats and cylinder liners extremely simple and fast, which greatly shortens the maintenance downtime and ensures the continuity of the operation.

Cylinder liner: the first line of defense

We provide cylinder liners of a variety of materials to meet the needs of different working conditions and budgets.

Piston: hydraulic energy engine

Polyurethane bonding piston:

Integrated bonding structure:Using a specially formulated polyurethane material, it is chemically bonded to the strong forged steel piston core into a whole. This kind of Seamless structure It fundamentally eliminates the common problems of delamination and medium intrusion of split pistons, and prevents abrasive mud from entering the piston and causing damage between the core. ULZ 000105 . ^.

"Double hardness" polyurethane technology: This is the core of our piston technology. The piston body is made of harder polyurethane material to provide sufficient rigid support and extrusion resistance; while the sealing lip is made of more tough and softer polyurethane material to ensure a dynamic and perfect seal with the inner wall of the cylinder liner. This kind of design makes lifeThe plug can still maintain excellent sealing performance and ultra-long service life at a pressure of up to 7,500 psi and a temperature of 220°F (104°C).

Rubber bonding/replaceable rubber piston: We also provide nitrile rubber pistons as a reliable choice in water-based mud or working conditions that focus on early procurement costs. Among them, the design of the replaceable rubber piston further reduces the cost of spare parts for a single maintenance.

Valve and valve seat: the guardian of flow

Materials and processes: The valve body and the valve seat are made of high-quality alloy steel, and through Carburizing heat treatment. The carburizing process forms an extremely hard wear-resistant layer on the surface of the component, while maintaining the good toughness of the internal core, so that it can not only resist wear, but also absorb the impact load caused by fluid pulsation without brittle fracture.

Structural design:We adopt the ** fully open, valve stem guide (or four-wing guide) ** design. Compared with the traditional design, the fully open valve seat provides a larger flow area, effectively reduces fluid resistance, improves the hydraulic efficiency of the pump, and can pass through the leakage material (LCM) more smoothly, reducing the risk of blockage. ^.

Sealing and plug-in: The valve plug-in is made of high-quality polyurethane material, which ensures reliable and durable sealing and is easy to replace.The contact surface of the valve body and the plug-in is designed with a serrated structure, forming a "breathless" seal, which prevents premature wear caused by small movement during the high-frequency switching process. ^.

Piston rod and clamp

Materials and processes: Piston rod selection Grayloy Or equivalent level of advanced heat-treated alloy steel manufacturing ^.The surface of the rod body passes throughInductive quenching Processed to obtain extremely high surface hardness, followed by precision grinding and mirror polishing. This ultra-smooth surface is for extensionThe life of the coil root seal in the packing box is very important, which can effectively prevent leakage between the hydraulic end and the power end. ^.

Clamp: Equipped with a high-strength, easy-to-operate piston rod clamp to ensure that the connection between the piston and the piston rod is firm and reliable.
