Overview
Boosting water injection pump is a special pump designed for high-pressure and high-power water injection conditions, which increases the liquid pressure to 10-50 times that of conventional pumps through mechanical boosting.
Product Details
In scenarios such as oilfield water flooding, deep-sea oil and gas extraction, and high-pressure cleaning, ordinary water pumps often cannot meet the high pressure requirementsBoosting water injection pumpIt becomes a critical device. It is like a "turbocharger" for fluid systems, which pressurizes water or liquid media to over 100MPa through multi-stage energy superposition, injecting strong power into industrial processes.
Boosting water injection pumpIt is a special pump designed specifically for high-pressure and high-power water injection conditions, which increases the liquid pressure to 10-50 times that of conventional pumps through mechanical boosting. Its core values are reflected in:
Energy development: In secondary/tertiary oil recovery in oil fields, water is injected into the formation to drive crude oil (pressure up to 35-50MPa).
Industrial cleaning: ultra-high pressure water jet (above 200MPa) cutting steel plates, rust removal and paint removal.
Deep sea operation: Provide stable high-pressure water source (pressure resistance level>100MPa) for the hydraulic system of underwater robots.
Technical positioning: Fill the pressure gap between centrifugal pumps (low pressure high flow) and plunger pumps (ultra-high pressure low flow), combining efficiency and reliability.
Working Principle:
Boosting water injection pumpMulti stage centrifugation or plunger diaphragm composite design is commonly used to achieve efficient energy transfer through stepped pressurization
1. Multi stage centrifugal boosting
Structure: Multiple impellers are connected in series, with each stage of impellers lifting a pressure of 5-15MPa.
Process: The liquid is accelerated by the first stage impeller, then slowed down and pressurized by the guide shell, and gradually transmitted to the final output stage.
2. Plunger diaphragm composite pressurization
Structure: The crankshaft drives the reciprocating motion of the plunger, and hydraulic oil drives the deformation of the diaphragm to achieve pollution-free boosting.
Advantages: Strong sealing performance, suitable for transporting corrosive and high-purity media (such as semiconductor ultrapure water).
Boosting curve:
Centrifugal: The flow pressure curve is gentle, suitable for continuous and stable water injection.
Piston type: with large flow pulsation but high pressure peak, suitable for short-term high-pressure operations.
