What causes the outlet pressure to drop when the compressed air booster pump is started?

Compressed air booster pumps are widely used in the industrial field, but in actual use, many users report that the outlet pressure drops instead of rises after startup. This phenomenon seems contradictory, but it involves multiple factors such as aerodynamic principles, system design defects, and insufficient operation and maintenance management. This article will combine professional theory with actual cases to analyze the core reasons for the pressure drop and provide optimization solutions.

 

1. Core reason: imbalance between compressed air supply and demand

The air booster pump is essentially a pneumatic device, and its working power depends on the supply of external compressed air. When the booster pump starts, it will consume additional compressed air flow. If the air compressor's air supply capacity is insufficient, the total system pressure will inevitably drop.

Data case: Assuming that the displacement of an air compressor is 1 m³/min, the original equipment (such as dry gas seal) consumes 0.6 m³/min, and the system pressure can be maintained at 0.6 MPa. If the booster pump needs to consume an additional 0.5 m³/min after starting, the total demand reaches 1.1 m³/min, which exceeds the air compressor's supply capacity, and the pressure drops sharply from 0.6 MPa to a lower level.

 

Theoretical basis:

According to the Bernoulli equation, the law of conservation of fluid energy shows that when the flow demand exceeds the supply, the ratio of kinetic energy converted into pressure energy is unbalanced, resulting in a pressure drop. At the same time, the relationship between flow and pressure follows the formula:

 

Q = A × v

 

(where Q is flow, A is cross-sectional area, and v is flow velocity)

When the flow velocity increases, the pressure can decrease, further exacerbating the insufficient outlet pressure.

 

2. Analysis of common specific reasons

 

1.Improper selection or performance degradation of air compressor

Selection error: The superimposed flow requirements of the booster pump and the original equipment were not calculated, resulting in insufficient air compressor capacity.

 

Performance degradation: After long-term use of the air compressor, problems such as piston wear and filter element clogging will reduce the actual displacement. For example, due to improper maintenance of the air compressor by a user, the actual displacement dropped from the nominal 1 m³/min to 0.8 m³/min, which could not meet the requirements of the booster pump.

 

2. Leakage or component failure of the air system

Pipeline leakage: Loose joints or damaged pipes will cause compressed air to lose and pressure cannot be effectively maintained.

 

Check valve failure: If the check valve is not sealed tightly, the pressurized air will flow back to the low-pressure side, forming pressure fluctuations or even continuous leakage.

 

Filter clogging: Filter clogging will increase air path resistance, resulting in local pressure loss and reducing effective output.

 

3. Insufficient air tank capacity

The air tank is used to balance system pressure fluctuations. If the capacity is too small, it will not be able to buffer the instantaneous flow demand when the booster pump is started, and the pressure drop will be more significant. For example, in one case, after the user replaced the 5L gas tank with a 50L one, the pressure stability increased by 40%.

 

3. Solutions and optimization suggestions

 

1. Accurate selection and flow calculation

Flow calculation: Before selecting the booster pump, the total required flow must be calculated

(Qtotal = Qequipment + Qbooster pump), and the air compressor displacement must be at least 1.2 times the total demand.

 

Matching gas tank capacity: Recommended gas tank volume

V≥Qtotal×t/60, where t is the shortest working cycle of the booster pump (unit: second).

 

2. System maintenance and troubleshooting

Regular inspection: Check the pipeline sealing, filter status and check valve function every month, and replace aging parts in time.

 

Air compressor maintenance: Clean the filter element and replace the lubricating oil according to the manual to ensure stable displacement. For example, Atlas Copco's preventive maintenance contract can reduce energy efficiency losses by 30%.

 

3. Technology upgrade and redundant design

Dual pump parallel: For high reliability scenarios, a dual booster pump parallel design is adopted. When a single pump fails, the other pump automatically fills the position.

 

Intelligent monitoring: Install pressure sensors and IoT modules to monitor pressure fluctuations in real time and issue early warnings. For example, Atlas Copco’s “Intelligent Star” system can identify leakage risks in advance.

 

 

How Kingsmagnet Flexible Rubber Magnetic Strips Are Made

Kingsmagnet’s rubber magnetic strips are flexible, elastic, and twistable magnets made by combining rubber with magnetic materials. The production process involves several key steps:

1. Raw Material Preparation

  • Magnetic Powder Selection:
    Depending on the desired performance, suitable magnetic powders such as barium ferrite or strontium ferrite are selected. Key properties like particle size, purity, and magnetic strength directly affect the final product.

  • Rubber Base Selection:
    Rubber materials such as neoprene, nitrile rubber, or EPDM are chosen as the carrier matrix. Each type of rubber offers specific advantages—like oil resistance, aging resistance, or flexibility—based on the end-use environment.

  • Additive Preparation:
    Additives such as curing agents, antioxidants, and fillers are prepared to enhance the rubber's processability and improve the strip’s physical and chemical stability.


2. Mixing

  • Equipment Setup:
    Open mills or internal mixers are used. Open mills mix materials using two rotating rollers, while internal mixers blend materials in a closed chamber using rotors.

  • Mixing Process:
    First, the rubber is plasticized to improve its processability. Then, magnetic powder and additives are added in a specific order and timing. Key factors like temperature, time, and mixing strength are carefully controlled to ensure uniform blending and product quality.


3. Forming

  • Extrusion:
    The mixed compound is pushed through an extruder to create continuous rubber magnetic strips with a desired cross-section. This method offers high efficiency for long-length production.

  • Calendering:
    The compound is flattened into sheets using calendering rollers, then cut or stamped into shape. Calendering produces smooth, evenly thick strips, ideal for thinner products.

  • Compression Molding:
    The compound is placed in a mold and formed under heat and pressure. This method is suited for complex shapes with high dimensional accuracy, often used in small-batch or precision applications.


4. Curing (Vulcanization)

  • Purpose:
    Vulcanization causes the rubber molecules to crosslink, forming a stable three-dimensional network. This enhances strength, hardness, elasticity, and resistance to aging.

  • Process:
    The curing method (e.g., hot air, steam, or flat-plate vulcanization) and parameters (temperature, time, pressure) are selected based on the rubber type and product needs.


5. Magnetization

  • Principle:
    A strong magnetic field is applied to align the magnetic domains in the powder, giving the strip its magnetic properties.

  • Methods:
    Depending on the product’s shape and magnetic requirements, techniques such as pulse or direct current magnetization are used, with precise control of parameters.


6. Post-Processing and Inspection

 

  • Finishing:
    The magnetic strips may be trimmed, cleaned, or coated with protective layers to enhance appearance and durability.

  • Quality Inspection:
    Finished products undergo thorough testing, including:

    • Magnetic properties (remanence, coercivity, intrinsic coercivity)

    • Physical properties (hardness, tensile strength, elongation)

    • Visual and dimensional checks
      Only qualified products are approved for market release.

What kinds of wiring harnesses are there in a car?

Introduction

In modern fuel-powered vehicles, the electrical system plays a crucial role, and the wiring harness is the "blood vessels" and "nerves" of the entire electrical system. It is responsible for transmitting power, signals and data to ensure the normal operation of various components such as the engine, lights, instruments and safety systems. So, what exactly are the wiring harnesses in a fuel-powered car? What are their respective functions?

 

 1. What is an automotive wiring harness?

A Wiring Harness for automobiles is an integrated system composed of multiple wires, cables, connectors, terminals, protective sleeves (such as tapes, bellows), etc. It is designed and assembled in accordance with the electrical layout of the vehicle to ensure that power, signals and data can be transmitted efficiently and stably.

Due to the complex internal environment of automobiles (high temperature, vibration, humidity, etc.), the wiring harness must meet the following requirements:

  • High-temperature resistant (The engine compartment can reach over 120℃)
  • Anti-vibration (preventing fracture caused by long-term vibration)
  • Waterproof and dustproof (especially in the chassis and engine compartment)
  • Electromagnetic shielding (to avoid signal interference

 

2. Classification of main wiring harnesses in fuel vehicles

The wiring harnesses of fuel vehicles are usually classified by functional areas and mainly include the following categories:

(1)Engine Harness

Function: Connect the engine control unit (ECU), sensors, actuators (such as fuel injectors, ignition coils), etc., to ensure the stable operation of the engine.

Main components:

  • ECU wiring harness: Transmits engine control signals (such as fuel injection, ignition timing).
  • Sensor wiring harness: Connects oxygen sensors, crankshaft position sensors, knock sensors, etc., providing real-time data.
  • Actuator wiring harness: Controls fuel injectors, throttle valves, idle motors, etc.

The dashboard displays the vehicle status (such as fault lights).

 

3. Common Faults and Maintenance of Automotive Wiring Harnesses

Although the wiring harness design is reliable, problems may still occur after long-term use:

(1) Common faults

  • Open circuit: Wire breakage (such as frequent opening and closing of car doors causing fatigue of the wiring harness).
  • Short circuit: The insulation layer is damaged, causing the positive and negative poles to come into contact (which may burn out the fuse).
  • Poor contact: Terminal oxidation or loosening (such as the headlights flickering on and off).
  • Corrosion: A humid environment causes the wiring harness to rust (especially the chassis wiring harness).

(2) Maintenance suggestions

  • Regularly inspect the appearance of the wiring harness (for any wear or aging).
  • Avoid modifying the circuit privately (which may cause overload or short circuit).
  • After wading through water, check whether the wiring harness has taken in water (especially the engine wiring harness).

 

4. Future trends: Lightweight and intelligent wiring harnesses

As the degree of automotive electronicization increases, wiring harnesses are also constantly evolving:

  • Lightweighting: Use aluminum wires and optical fibers to replace some copper wires (such as Tesla reducing the length of wire harnesses).
  • High-speed data transmission: Supports in-vehicle Ethernet (for autonomous driving and high-definition cameras).
