mud pump valve guide brands

Upper and lower valve guides are important parts for the fluid end of mud pump in oil drilling. The upper type acts as a connector of valve spring and valve cover inside the hydraulic cylinder. It plays a guiding role in valve operation. The lower one is a connector of valve spring and hydraulic cylinder inside the cylinder. It has the function of fixing and guiding the valve operation.

In most types of reciprocating engines, a valve guide is provided for each poppet valve in the cylinder head. Along with the valve spring, it serves to positively locate the valve so that it may make proper contact with the valve seat. A valve guide is a cylindrical piece of metal, pressed or integrally cast into the cylinder head, with the valve reciprocating inside it. Guides also serve to conduct heat from the combustion process out from the exhaust valve and into the cylinder head where it may be taken up by the cooling system. Bronze is commonly used, as is steel; a balance between stiffness and wear on the valve is essential to achieve a useful service life.

The clearance between the inner diameter of the valve guide and the outer diameter of the poppet valve stem is critical for the proper performance of an engine. If there is too little clearance, the valve may stick as oil contaminants and thermal expansion become factors. If there is too much clearance, the valve may not seat properly and excessive oil consumption can occur.

Over time, the inner diameter of the valve guide and the outer diameter of the valve stem may become worn. In the 1980s, many U.S. production engine remanufacturers began reaming valve guides, rather than replacing them, as part of their remanufacturing process. They found that by reaming all the valve guides in a head to one standard size (typically 0.008 in. diametrically oversized), and installing remanufactured engine valves having stems that are also oversized, a typical engine head can be remanufactured in much less time.[1] Since the reaming process leaves the valve guide with a much better surface finish and shape than typical replacement guides, and since the oversize valves often have chrome plated stems, remanufacturers also discovered that valve train warranty issues are virtually eliminated.

Studies have been conducted which show that through the proper selection of the reamer and reaming process, valves guides can be quickly and efficiently reamed to a consistently repeatable size.

Customers said they wanted long-lasting, easy-to-use valves and seats, and we delivered. Made from domestically sourced steel, GD Energy Products valves feature a two-piece friction-welded design, proprietary bonded inserts, and innovative geometry to deliver significantly longer life. GD Energy Products’ field proven Valves & Seats meet API Standard, and come with our “Ready Inventory” promise that we’ll have it in stock, when you need it.

Our full-open valves and seats are designed for use in GD Energy Products PZ, F-Series, and National 12P lines of triplex drilling pumps. This gives you options to use these parts across your whole fleet of pumps.

The Caliber® 4-web valve and seat are designed for today’s high pressure drilling conditions. Each piece is forged from a single piece of proprietary, high-strength alloy steel and is case hardened to precisely controlled levels. We have molded our high temperature, high impact resistant urethane to the valve body in order to eliminate the existing gap you will find on replaceable insert type valves.

The 4-web design holds the valve weight to a minimum by increasing the load bearing area. In order to allow quick flushing of solid matter we use a steep angle that also increases the metal-to-metal sealing area. Each part is individually inspected to ensure performance and satisfaction.

Mud Pump Valve & Seat are made of premium alloy steel through one-piece forging and carburizing treatment processes, thereby ensuring high intensity. In addition, the precise calculation is performed and CNC machining is conducted for the dimensional matching of the valve seat and valve body working angles to enhance the service life of the valve body and valve seat. Our valve products are able to work smoothly in normal mining and digging conditions for over 400 hours.

A mud pump (sometimes referred to as a mud drilling pump or drilling mud pump), is a reciprocating piston/plunger pump designed to circulate drilling fluid under high pressure (up to 7,500 psi or 52,000 kPa) down the drill string and back up the annulus. A mud pump is an important part of the equipment used for oil well drilling and manufactured according to API specification 7K.

The advantages of the drilling mud pump include the ability to move high-solids-content fluids laden with abrasives, the ability to pump large particles, ease of operation and maintenance, reliability, and the ability to operate over a wide range of pressures and flow rates by changing the diameter of pump liners and pistons.

The fluid end includes cylinders (module), valve assembly, cylinder liners, piston assembly, suction manifold, discharge manifold, piston rod, pulsation dampener assembly, etc.

As an important equipment for oilfield drilling operation, a drilling mud pump delivers circulating high-pressure drilling fluid or drilling mud to the bottom of the oil well, flushes the bottom of the well, breaks the rock, cools, lubricates and clean the drill bit, and carries the cuttings back to the ground.

The drilling mud is also used to suspend and carry out drill cuttings from the drill bits as it is brought in and out of the hole. This ensures that the drill bit does not clog and overheat, and makes the entire drilling operation smooth and safe.

Rotational power is supplied to the mud pump through an external power source like a diesel engine or electric motor. The power end of the mud pump converts the rotational energy through a crankshaft to a reciprocating motion of pistons.

The pistons move back and forth in mud pump liners, exerting a force on the cylinder chamber. During the retraction of the piston, valves open to allow the fluid to be drawn into the cylinder. Once the piston has fully retracted, it is pushed back into the cylinder.

At this time the intake valves are closed and the exhaust valves open, allowing the piston to force the fluid out of the cylinder under pressure. Once the piston reaches its maximum depth into the cylinder, the exhaust valves close and the process repeats.

For Fluid End: piston rod clamp, piston rod, piston assembly, cylinder cover, liner, liner flange, wear plate, cylinder, valve assembly, valve cover, valve guide, flashboard assy., cylinder cover flange, cylinder head, gaskets, studs, nuts, seal rings, pulsation dampener, bladder, discharge manifold, suction manifold, etc.

We also maintain a large inventory of spare parts for most of the valves we carry, including drive bushings and rotating heads from Kelly and other well-known brands.

realize longer usage life. Top and bottom guide plate are adopted in mud pump, and concentricity can be adjusted through bottom plate plus spacer. Connection between crosshead and central pull rod is flanged which is pin matched hole. This rigid connection can ensure concentricity between central rod and crosshead. The central rod is connected with piston rod through hub and this light hub can ensure reliable connection between them.

Cylinder is forged by alloy steel and the three cylinders on mud pump can be exchanged. Thorough structure design, which is valve on valve, can reduce cylinder volume and to improve volume efficiency. Cylinder surface can coated nickel to improve its corrosion resistance performance if clients require. Discharge compressor, shear pin safety valve and discharge filter screen are mounted on each discharge outlet of three cylinders. Discharge outlet is 5 1/8″5000psi flange

Spray pump is centrifuge pump and can be driven through belt which pulley is mounted on the extend end of the inlet shaft or electrical motor directly. Water is adopted to cool and lubricate it.

Pressure lubrication combining splash lubrication is adopted for power end. Pressure oil pumped by gear oil pump in the oil tank is transmitted to crosshead, middle pull rod, crosshead guide and bearings through lubrication pipe line. Working condition of gear oil pump can be watched from pressure gauge in the back of the shell.

Suction system is used for preventing air block due to low air pressure of pump inlet. Suction system is composed by base, butterfly valve and manifold. Suction pump on the suction manifold can be driven by electrical motor or by belt on the inlet shaft of mud pump to reduce power consumption.
