Cause of pump dosing hot

Introduction

Dosing pump overheating is one of the common problems in various industries that can lead to reduced efficiency, increased repair costs, and even downtime. In this article, we will examine the main causes of overheating of dosing pumps, diagnostic methods, and practical solutions to prevent and fix this problem.

1. Normal dosing operation of the pump and standard temperature

Dosing pumps have a working temperature between 40 and 70 degrees Celsius under normal operating conditions. Temperatures above this range are a sign of a problem that should be investigated immediately.

1.1. Symptoms of abnormal overheating of the dosing pump

  • Noticeable increase in pump body temperature

  • Oil or hydraulic fluid discoloration

  • The smell of burns or smoke

  • Reducing pump outlet flow

  • Increased energy consumption

2.7 The main reason for the overheating of the dosing pump

2.1. Lubrication problems (50% of cases)

  • Lack of oil or grease in mechanical parts

  • Using the wrong oil with the wrong grade

  • Wear and tear of hydraulic fluid and reduced lubrication property

2.2. Overload on the pump (25% of cases)

  • Blockages in the injection line or captured filters

  • High viscosity of the fluid compared to the original design

  • Incorrect setting of system working pressure

2.3. Mechanical problems (15% of cases)

  • Wear of bearings and bearings

  • The pump shaft is not aligned with the motor

  • Crash couplings and create vibration

2.4. Improper system design (5% of cases)

  • Mismatch of pump capacity with system requirements

  • Defects in the cooling system

  • Choosing the wrong material for the working conditions

2.5. Environmental conditions (3% of cases)

  • High ambient temperature (more than 45°C)

  • Improper ventilation of the pump installation site

  • Dust penetration into mechanical parts

2.6. Electrical problems (2% of cases)

  • Inappropriate motor feeding voltage

  • Failure of coils and overload

2.7. Operator Error

  • Dry Runing

  • Improperly change settings without expertise

3. Methods of Detecting the Cause of Hot Spots

3.1. Preliminary Examinations

  1. Touching the pump body (with caution)

  2. Oil level and quality control

  3. Checking for unusual sounds

  4. View Pressure Indicators

3.2. Specialized Tests

  • Measurement of point temperature with infrared thermometer

  • Pump Vibration Analysis

  • Engine A’s Test

  • Flow flow investigation with flumeter

4.10 Practical Strategies for Elimination and Prevention

4.1. Immediate Solutions

  1. Stop the pump in case of temperature above 90 degrees

  2. Check filters and replace as needed

  3. Adjusting work pressure according to catalog

4.2. Medium-term solutions

  1. Changing oil and grease with standard type

  2. Alignment of shafts by expert

  3. Auxiliary Cooling System Installation

4.3. Long-Term Solutions

  1. Periodic inspection every 3 months

  2. Annual Oil Analysis

  3. Training of Operators

  4. Control System Upgrade

5. Quick Faulting Table

Symptoms The most likely cause Immediate action
Localized Heat Bearing Failure Stop & Replace
General Heat Oil Shortage Adding oil
A Heat with Sound Heterocentrism Shaft Adjustment
Hot with decreasing discharge Clogged Check Filters

Safety tips when dealing with a hot pump

  1. Use of thermal gloves

  2. Avoid sudden cooling

  3. Proper ventilation of the environment

  4. Power outages before repairs

7. Time to replace the dosing pump

  • Noticeable deformation of the body due to heat

  • Permanent reduction in efficiency after repairs

  • Repair cost more than 60% of the new price

8. Conclusion

pump’s dosing is a clear sign of a problem in the system that should not be ignored. With timely diagnosis of the cause and implementation of preventive solutions, 80% of overheating cases can be prevented. Preventive maintenance and the use of high-quality parts is the best way to extend the life of the dosing pumps and avoid costly production stoppages.
