A piston mud pump, also known as a reciprocating mud pump, is a type of positive displacement pump commonly used in various industries, particularly in drilling operations. It is designed to handle the demanding task of circulating drilling mud with high pressure and flow rates.   The piston mud pump derives its name from the reciprocating motion of the pistons inside the pump. These pistons move back and forth in synchronization, creating alternating suction and discharge strokes. As a result, the pump effectively pushes the drilling mud through the system, maintaining circulation and delivering it to the desired location.   The design of a piston mud pump typically consists of multiple cylinders or fluid chambers, each housing a piston. When the piston moves back, it creates a vacuum that draws the mud into the chamber through an inlet valve. On the forward stroke, the piston pushes the mud out through a discharge valve and into the circulation system.   One notable advantage of piston mud pumps is their ability to generate high pressures, making them suitable for challenging drilling operations. They can handle thick and abrasive drilling fluids, such as drilling muds or other mixtures of water, solids, and additives. The robust construction and durability of piston mud pumps contribute to their reliability and longevity in demanding environments.   Elephant Machinery CO.,LTD is a reputable manufacturer of piston mud pumps.

A diesel engine mud pump is a specialized type of reciprocating pump used in various industries, particularly in drilling operations. It is specifically designed to handle demanding drilling conditions where a reliable and portable source is required.   The diesel engine mud pump combines a diesel engine with a mud pump, providing a self contained unit that delivers high pressure fluid for drilling purposes. The diesel engine serves as the power source, driving the mud pump's reciprocating pistons or plungers to generate the required pressure for circulating drilling mud.   The diesel engine offers several advantages for mud pump applications. Firstly, it provides a reliable and efficient power source that operates independently of electrical grids or power supply infrastructure. This makes diesel engine mud pumps suitable for remote or off grid drilling sites.   Additionally, diesel engines are known for their durability and robustness, making them well-suited for rugged drilling environments. They can handle high loads and continuous operation without compromising performance.   The mud pump component of the diesel engine mud pump is responsible for creating the required pressure to circulate drilling mud. It typically consists of multiple pistons or plungers that work in a synchronized manner to create a smooth and constant flow of mud. This circulation helps cool the drill bit, carry away rock cuttings, and maintain optimal drilling conditions.   Elephant Machinery CO.,LTD, a reputable manufacturer of mud pumps, offers a range of diesel engine mud pumps that meet the industry's rigorous standards. Their pumps are designed for reliability, durability, and efficient performance, ensuring smooth drilling operations in various applications.

Drilling mud pumps are critical equipment in drilling operations, and mud pump wearing parts are essential to keep them operating efficiently. How to disassemble the mud pump wearing parts?   1. Piston / Plunger: remove the liner cover clamping nuts, loose the thick and thin nuts of the linking rod inside the liner, and then take the liner out by special piston disassembly tool.     2. Liner: after the disassembly of the pump head and then piston as per above procedure, put a special tool – jacking plate in-between the linking rod and the liner, rotate the pump until the linking rod push the liner out.    3. Valve Seat: take away valve cover firstly, and then disassemble the valve seat with special tool to remove the valve seat.    4. Linking Rod Seal: after taking out the liner, loose the connection between the linking rod and cross-head, disassemble the linking rod, and then open the clamping cover above the linking rod seal, now the seal can be taken out for replacement.    5. Safety Valves’ Spring: open the protection cover at the top of the valve, loose the adjusting bolts, remove the valve cover, and then the valve spring can be taken out for replacement.    6. Pressure Relief Valve: disassemble the valve lever firstly, then loose the jam nut, round nut and seal nuts, etc., then such valve parts as the V-shape seals, seal seat, valve levers can be replaced; further, loose the connection bolts beneath the valve body, then the valve seat can be removed for replacement.   The above methods are only for horizontal mud pump products of Elephant brand.

The service life of reciprocating mud pump not only relates with design and manufacture but also relates with pump’s service condition, operating and maintenance.  Once the triplex mud pump is installed or stopped for a long time, the following preparations must be carried out: 1. Check whether the fuel tank is full of fuel, whether the water tank is full of coolant, and whether the pump is full of lubricating oil   2. The mud pump is connected with the main equipment by a high-pressure water supply pipe.   3. Open the valves in the pipeline system.   4. Check whether the circuit and oil circuit of the diesel engine are normal, whether the instrument is in good condition and whether the oil and water are enough.   5. Check whether the operation handles and switches are in the initial position.   6. If a mud pump package is newly assembled or has experienced long time stoppage, then below preparations must be arranged in advance before startup:  (1) Check the suction pipe and pump valve, the suction port is not blocked by foreign matter, the pump valve is opened and closed smoothly, the suction pipe is in good sealing condition, and there is no leakage. The suction end of the suction pipe should be 0.3~0.5m below the water, and 0.5m away from the bottom and side wall of the water pool or tank.  (2) Please check the Net Positive Suction Head (NPSH) should be no more than 2.5m for clean water, and the value will be decreased if the medium is thick mud. In addition, the suction pipe length should be no longer than 5 meters.    7. Please make sure that specified brands of lubrication oil or grease shall be added into the pump body, all the oil cups and grease fittings until reaching right oil level.    8. Please make sure that all the components and parts are well tightened, especially the critical connection between piston and crosshead/connection rod.    9. Please check if the pressure gauge works well, and if its scale is in ‘0’ position when there is no pressure.    10. Before starting the pump, fill hydraulic 46 wear-resistant hydraulic oil into the oil discharge port of the hydraulic motor   11. Please fully open the pump relief valves before startup so that it is in idle load condition.    The above methods are only for rig mud pump products of Elephant brand.
