Mud pump is the key equipment in drilling operation. If mud is compared to blood in drilling operation, mud pump is the heart of blood supply in drilling production. Therefore, its importance in drilling production is self-evident, and the spare parts of mud pump play a certain role in this.

Mud pump is a kind of machine which can transport mud or water to drill hole in the process of drilling. It is an important part of drilling equipment. Its main function is to inject mud into the well with the bit, cool the bit, clean the drilling tool, stabilize the well wall, drive the drilling, and bring the cuttings back to the ground after drilling.

In the normal circulation drilling, the mud pump is to send the surface flushing medium - clear water, mud or polymer flushing liquid under a certain pressure through the high-pressure hose, faucet and the center hole of drill string directly to the bottom of the drill bit, so as to cool the drill bit, remove the cuttings and transport them to the surface. The mud pump is driven by the power machine to rotate the crankshaft of the pump. The crankshaft drives the piston to do reciprocating motion in the pump cylinder through the crosshead. Under the alternating action of the suction and discharge valves, the purpose of pressing and circulating the flushing fluid is realized. Different types of mud pumps are used in different cases to ensure the smooth proceeding of the drilling operation.

According to the use of the mud pump, the leakage of the valve box, the burning of the bearing and the abnormal noise are all frequent faults that affect the normal use of the mud pump. Therefore, careful study of the causes of the problem plays a key role in prolonging the service life of the mud pump. At this time, a certain amount of spare parts of the mud pump are needed.

In the process of using the mud pump, the equipment failures caused by specific reasons are different. Reasonable use and maintenance of the equipment can extend the service life of the equipment. At the same time, in strict accordance with the basic elements of normal operation of the drilling pump, "medium power, medium pump pressure, medium speed operation, tight, tight, leak tight, pump pressure does not fluctuate, temperature is normal, sound is normal", the operation can ensure the good operation of the equipment. Of course, it"s also important to find the right mud pump spare parts!

The fluid end of a duplex or triplex pump offers hundreds of opportunities for error. The results of an error in such a high-pressure system can mean (1) expensive downtime on the pump and maybe the entire rig, (2) expensive repair-replacement, and (3) possible injury or death of a crewman or a company man. Under the laws of nature, pump pistons and liners will wear, and there will be some corrosion and metallurgical imperfections, but the majority of pump failures are manmade. Theoretically, thorough training and retraining should avoid most mud pump problems. Realistically, a critical failure analysis during repair will be necessary to determine how to correct the failure. Telltale signs of trouble are distortion of piston rods, frayed piston polymer, discoloration, odor, hard-to-remove piston, rod cracks, pitting, total fracture, valve seat wear, and unsuitable external appearance.

abstractNote = {Failure of a liner seal is one of the more critical failures on a mud pump because this seal interfaces with the pump body. Therefore, failures, usually damage the pump body, leading to repair or replacement of the fluid end itself. One of the more common liner seal problems involves counter-bore-type seals. This type of seal is easily affected by two aspects of the problem that are found in the mud pump fluid end-wear and foreign matter in the seal groove. Factors relative to difficult liner removal are discussed. Piston damage, careless seal installation and corrosion damage are also examined.},

Mud Pumps are generally used in rural areas as river mud, manure, river water, slurry feed, suction and irrigation, instead of shouldering human burdens, and used for drainage and drought resistance. It can also be used for car front, river mud, and fertilizer production. It can also be used as a simple mobile fire-fighting pump in rural areas, and can also be used for fish farming to bring water to clear ponds and fish ponds to increase oxygen. It can also be used in municipal, chemical, printing and dyeing, medicine, shipbuilding, foundry, food and other industries to suck thick liquid, dirty liquid, paste, quicksand and flowing sludge from urban rivers, etc. It can be used as a coal mine to remove small gravels containing mud Fluid. If it is combined with a high-pressure water pump and a water gun to form a hydraulic mechanized earthwork unit, it can be used for excavation and transportation of land leveling, river courses, ponds, air defense, and underground projects.

Reasons: insufficient filling and diversion of water, inability to discharge the air in the pump, air leakage in the suction pipe, large clearance between the front liner and the impeller

Reason: there is air in the Pump, the gap between the impeller and the front liner is large, the clutch is not closed tightly, the impeller or the liner is worn

Many things go into getting the most life out of your mud pump and its components — all important to extend the usage of this vital piece of equipment on an HDD jobsite. Some of the most important key points are covered below.

The most important thing you can do is service your pump, per the manufacturer’s requirements. We get plenty of pumps in the shop for service work that look like they have been abused for years without having basic maintenance,  such as regular oil changes. You wouldn’t dream of treating your personal vehicle like that, so why would you treat your pump like that.

Check the oil daily and change the oil regularly. If you find water or drilling mud contamination in the oil, change the oil as soon as possible. Failure to do so will most likely leave you a substantial bill to rebuild the gear end, which could have been avoided if proper maintenance procedures would have been followed. Water in the oil does not allow the oil to perform correctly, which will burn up your gear end. Drilling mud in your gear end will act as a lapping compound and will wear out all of the bearing surfaces in your pump. Either way it will be costly. The main reasons for having water or drilling mud in the gear end of your pump is because your pony rod packing is failing and/or you have let your liners and pistons get severely worn. Indication of this is fluid that should be contained inside the fluid end of your pump is now moving past your piston and spraying into the cradle of the pump, which forces its way past the pony rod packing. Pony rod packing is meant to keep the oil in the gear end and the liner wash fluid out of the gear end. Even with brand new packing, you can have water or drilling fluid enter the gear end if it is sprayed with sufficient force, because a piston or liner is worn out.

There is also usually a valve on the inlet of the spray bar. This valve should be closed enough so that liner wash fluid does not spray all over the top of the pump and other components.

Liner wash fluid can be comprised of different fluids, but we recommend just using clean water. In extremely cold conditions, you can use RV antifreeze. The liner wash or rod wash system is usually a closed loop type of system, consisting of a tank, a small pump and a spray bar. The pump will move fluid from the tank through the spray bar, and onto the inside of the liner to cool the liner, preventing scorching. The fluid will then collect in the bottom of the cradle of the pump and drain back down into the collection tank below the cradle and repeat the cycle. It is important to have clean fluid no matter what fluid you use. If your liners are leaking and the tank is full of drilling fluid, you will not cool the liners properly — which will just make the situation worse. There is also usually a valve on the inlet of the spray bar. This valve should be closed enough so that liner wash fluid does not spray all over the top of the pump and other components. Ensure that the water is spraying inside the liner and that any overspray is not traveling out of the pump onto the ground or onto the pony rod packing where it could be pulled into the gear end. If the fluid is spraying out of the cradle area and falling onto the ground, it won’t be long before your liner wash tank is empty. It only takes a minute without the cooling fluid being sprayed before the liners become scorched. You will then need to replace the pistons and liners, which is an avoidable costly repair. Make a point to check the liner wash fluid level several times a day.

Drilling fluid — whether pumping drilling mud, straight water or some combination of fluid — needs to be clean. Clean meaning free of solids. If you are recycling your fluid, make sure you are using a quality mud recycling system and check the solids content often throughout the day to make sure the system is doing its job. A quality mud system being run correctly should be able to keep your solids content down to one quarter of 1 percent or lower. When filling your mud recycling system, be sure to screen the fluid coming into the tanks. If it is a mud recycling system, simply make sure the fluid is going over the scalping shaker with screens in the shaker. If using some other type of tank, use an inline filter or some other method of filtering. Pumping out of creeks, rivers, lakes and ponds can introduce plenty of solids into your tanks if you are not filtering this fluid. When obtaining water out of a fire hydrant, there can be a lot of sand in the line, so don’t assume it’s clean and ensure it’s filtered before use.

Cavitation is a whole other detailed discussion, but all triplex pumps have a minimum amount of suction pressure that is required to run properly. Make sure this suction pressure is maintained at all times or your pump may cavitate. If you run a pump that is cavitating, it will shorten the life of all fluid end expendables and, in severe cases, can lead to gear end and fluid end destruction. If the pump is experiencing cavitation issues, the problem must be identified and corrected immediately.

The long and the short of it is to use clean drilling fluid and you will extend the life of your pumps expendables and downhole tooling, and keep up with your maintenance on the gear end of your pump. Avoid pump cavitation at all times. Taking a few minutes a day to inspect and maintain your pump can save you downtime and costly repair bills.
