The triplex plunger pump is a positive displacement reciprocating pump, and its core working principle is based on "the reciprocating movement of the plunger changing the volume of the pump chamber" to achieve liquid transportation. The motor drives three plungers to alternately reciprocate through the crankshaft connecting rod mechanism: when the plunger extends outward, the volume of the pump chamber increases to form negative pressure, the suction valve opens, and the liquid is sucked in; when the plunger compresses inward, the volume of the pump chamber decreases, the pressure rises, the discharge valve opens, and the liquid is discharged at high pressure.
Compared with other types of pumps such as gear pumps and vane pumps, the structural design of the triplex plunger pump gives it significant advantages in high-pressure scenarios:
1. Strong high-pressure output capacity: The precise fit between the plunger and the pump cylinder (gap is usually less than 0.01mm) reduces the leakage of high-pressure liquid, allowing its working pressure to reach 10-100MPa, and some special models even exceed 300MPa, which is far beyond the pressure range of ordinary positive displacement pumps. It is suitable for high-pressure cleaning, water pressure testing and other scenarios.
2. High flow stability: The three plungers are distributed at an angle of 120°, alternately performing the suction and discharge process. The flow fluctuation coefficient after superposition is less than 5%, and there is no need to install additional large-scale pressure stabilizing devices, which can meet the processes requiring high flow stability (such as precision spraying, chemical agent metering).
3. Good wear resistance and maintainability: Key components (plungers, seals) mostly use high-strength materials (such as ceramic plungers, polytetrafluoroethylene seal rings), which have strong wear resistance and a service life of 8000-12000 hours; at the same time, the modular structural design makes the replacement of vulnerable parts convenient, and the maintenance cost is 20%-30% lower than that of plunger pumps.
Based on the core advantages of high pressure, stability and durability, triplex plunger pumps have penetrated into many industries and become key power equipment:
1. Industrial cleaning field: In high-pressure deburring and surface derusting in industries such as auto parts and construction machinery, triplex plunger pumps can provide high-pressure water flow of 50-100MPa, and achieve efficient cleaning with special nozzles. The cleaning efficiency is more than 40% higher than low-pressure cleaning.
2. Petrochemical and energy industry: Used for oilfield water injection (injecting high-pressure water into the oil layer to improve oil recovery) and pipeline pressure testing (such as water pressure testing of natural gas pipelines). Its high-pressure stability can ensure operation safety and avoid pipeline leakage risks caused by pressure fluctuations.
3. Food and pharmaceutical industry: Triplex plunger pumps made of stainless steel can be used for high-pressure transportation of food raw materials (such as jam, syrup) and CIP (Cleaning-in-Place) of pharmaceutical equipment. They comply with food-grade hygiene standards (such as 3A certification) to avoid material contamination.
4. Civil and environmental protection fields: Used for high-pressure sludge dewatering in municipal sewage treatment; in the agricultural field, it cooperates with atomizing nozzles to realize high-pressure pesticide spraying, making the droplets more uniform, improving pesticide utilization rate by 30% and reducing environmental pollution.
