Precautions for Emulsion Gourd (Emulsion Pump/Equipment) at Different Stages of Use

To ensure safe, efficient, and long-lasting operation of emulsion-handling equipment (referred to as "emulsion gourd"), precautions must be taken at installation, operation, maintenance, and storage stages. Below is a structured guide:

1. Precautions During Installation Stage

(1) Proper Location Selection

Avoid contamination sources: Install away from dust, chemicals, or moisture to prevent emulsion degradation.

Stable foundation: Ensure the pump is mounted on a level, vibration-free surface to prevent misalignment.

Adequate ventilation: If motor-driven, provide sufficient airflow to prevent overheating.

(2) Correct Piping and Connection

Avoid sharp bends: Use gradual bends in suction/discharge lines to reduce pressure loss.

Secure fittings: Tighten all bolts, clamps, and hoses to prevent leaks.

Check orientation: Ensure the pump is installed in the correct direction (arrow marked on casing).

(3) Electrical Safety (If Motor-Driven)

Grounding: Connect the motor to a proper earth ground to prevent electric shock.

Voltage compatibility: Verify that the power supply matches the pump’s rated voltage.

Cable protection: Use conduit or armored cables to prevent damage.

(4) Pre-Operation Checks

Prime the pump: Fill the suction line with emulsion to avoid dry running.

Check rotation direction: Manually rotate the shaft to ensure smooth movement before powering on.

2. Precautions During Operation Stage

(1) Avoid Overloading

Stay within rated pressure/flow: Do not exceed the pump’s maximum capacity to prevent overheating or mechanical failure.

Monitor pressure gauges: Sudden drops may indicate leaks or cavitation.

(2) Prevent Cavitation

Maintain suction head: Ensure the emulsion level in the reservoir is high enough to prevent air ingestion.

Avoid restrictive suction lines: Use large-diameter pipes to reduce friction losses.

(3) Control Emulsion Temperature

Avoid excessive heating: If the emulsion becomes too hot, it may lose viscosity or degrade.

Use cooling systems (if applicable): For high-temperature applications, install heat exchangers.

(4) Monitor for Abnormalities

Listen for unusual noises: Grinding, knocking, or vibrations may indicate worn bearings or misalignment.

Check for leaks: Regularly inspect joints, seals, and hoses for drips or spray.

(5) Avoid Prolonged Idle Runs

Do not run dry: If the pump loses suction, stop immediately to prevent seal damage.

Use bypass valves (if available): Redirect flow during short stops to maintain lubrication.

3. Precautions During Maintenance Stage

(1) Scheduled Inspections

Daily checks:

Verify pressure and flow rates.

Inspect for leaks or overheating.

Weekly/Monthly tasks:

Clean or replace suction/discharge filters.

Lubricate bearings and shafts.

Tighten loose fittings.

(2) Component Replacement

Use genuine parts: Replace seals, O-rings, and valves with manufacturer-approved components.

Avoid mixing materials: Ensure compatibility between emulsion and pump materials (e.g., stainless steel for corrosive fluids).

(3) Alignment and Calibration

Realign after disassembly: If the pump is removed for repairs, ensure proper shaft alignment before reinstallation.

Calibrate pressure relief valves: Set to the manufacturer’s recommended pressure to prevent overpressure.

(4) Safety During Repairs

Isolate power: Disconnect electrical supply before opening the pump.

Vent pressure: Release residual pressure in the system before disassembly.

Wear PPE: Use gloves, goggles, and protective clothing when handling emulsions or sharp components.

4. Precautions During Storage/Long-Term Shutdown

(1) Proper Draining

Flush the system: Run clean water or a flushing agent to remove residual emulsion.

Drain completely: Open all valves and plugs to prevent corrosion.

(2) Lubrication Preservation

Coat internal parts: Apply a thin layer of rust inhibitor or grease to prevent oxidation.

Rotate shafts manually: Prevent seizing by turning the shaft occasionally.

(3) Environmental Control

Store indoors: Protect from rain, humidity, and extreme temperatures.

Cover the pump: Use a dust cover to prevent contamination.

(4) Recommissioning Checks

Inspect before restart: Check for rust, debris, or damaged seals.

Prime again: Ensure the suction line is filled before operation.

5. Additional Safety Precautions

Training for operators: Ensure personnel understand proper startup/shutdown procedures.

Emergency shutdown plan: Install a panic button or automatic cutoff in case of leaks or overpressure.

MSDS compliance: Follow Material Safety Data Sheet (MSDS) guidelines for emulsion handling.
