The drilling mud pump is a new type of product developed for the development of new drilling technologies in recent years, such as hydraulic impact drilling, screw drilling, and turbo drilling, in Chinese geological exploration. It not only supplies flushing fluid (mud or water) into the borehole during core drilling to circulate it in the borehole, carrying rock debris back to the surface, keeping the bottom of the hole clean, and cooling and lubricating the drill bit and drilling tools, protecting the hole wall from collapse, but also serves as a power source to drive the impactor (or screw, worm gear) to assist in drilling. Therefore, the drilling mud pump is one of the important equipment for modern drilling.
The drilling mud pump is especially suitable for grouting pump for various soft soil foundations. The performance of the horizontal triplex single-acting piston pump with two cylinder diameters and four gears make it possible to choose from eight flow rates. It is mainly used for hydraulic impact drilling within a main hole depth of 1500 meters, and can also be used for screw drilling and worm gear drilling within a main hole depth of 2000 meters, and it can also be used for ordinary core drilling within a main hole depth of 3000 meters. Because it adopts the advanced structural characteristics and various new materials of pumps in the world, especially the design of crankcase and gearbox, the drilling mud pump not only has reliable performance and longer service life of wearing parts, but also has a small volume and light weight, easy to disassemble, and convenient for mountain transportation, making it an ideal equipment for geological exploration. It can also be used for engineering construction drilling, water well drilling, sugar making, wine making, embankment grouting, and other various purposes.
The flushing fluid used for the drilling mud pump should not contain chemicals that have a corrosive effect on metal and rubber parts, and the temperature should not exceed 50°C. When using the drilling mud pump, the recommended specific gravity is 1.03~1.12, the viscosity is 18~25 seconds, the sand content is not greater than 4%, the maximum sand particle diameter should be less than 3 millimeters, and the PH value of the mud is 7~8 without mud clumps, weeds, leaves and other clogging impurities such as filter.
To ensure the normal operation of the pump, it is necessary to check the working conditions of the pump regularly and timely eliminate any defects found to avoid accidents.
Connection between various components, fixing of the frame on the foundation. Tension of the belt, oil level of the lubricating oil in the pump body. It needs to be done once per shift.
Tightening of the drain hose and whether the filter is blocked. It needs to be done once per shift.
Fastening of the connecting rod cover, pull rod and drill bit.
Anti-dust sealing of the inlet and outlet valves, pull rods, and pistons.
Connecting rod bearing, gear, bearing, safety valve, clutch, three-way.
Regular disassembly and cleaning, and inspection of various parts.
