As we all know, hydraulic gear pump is one of the indispensable equipment in many industries and manufacturing operation centers. However, any inefficiency in the operation of the pump will increase the indirect cost of the equipment and reduce the company’s bottom line. However, we can do it in many ways. To optimize the energy consumption of the pump, the editor has sorted out 7 methods, as follows:
1. Choose the right size pump
When optimizing energy consumption, the size of the pump and the size of the motor are essential considerations. When engineers try to introduce safety factors in the design phase, size problems often arise. This leads to oversized pumps, which increases maintenance requirements and energy consumption.
2. Choose the right pump type
Many factors can distinguish a single pump. Industrial and manufacturing facilities must carefully analyze various factors, such as the type of drive, the power required, the availability of auxiliary equipment, the speed, and the type of mechanical seal of a single pump.
Manufacturing and industrial operations must match these factors of hydraulic gear pumps to make them most suitable for specific applications. In order to determine the correct pump type, the pump manufacturer needs to communicate and collaborate carefully and thoroughly with the designated engineer responsible for the relevant project.
3. The system pressure drop is not allowed to be too large
Control system pressure drop to avoid energy waste. If your pumping equipment has a system pressure drop problem, you can reduce the pressure drop by adjusting the pipe size. Incorrect pipe size means that energy loss is caused by friction between the two ends of the pipe.
Other factors that affect the pressure drop of the system include the surface characteristics of the pipe, the characteristics of the hydraulic fluid, the flow rate and the pipe diameter. Adjusting these factors can sometimes solve the system pressure drop problem.
4. Use multiple pumps
Multiple pumps working in series are usually more energy-efficient than a single pump. If you are concerned about the increase in energy consumption associated with pumps, please consider implementing a multi-pump parallel system.
Remember that a single pump should be operated separately in a multi-pump parallel system, not at the same time, to maximize energy efficiency. However, in some cases, it is the best choice to run multiple pumps at the same time according to the flow requirements of the relevant application.
5. Trim the impeller
You can fine-tune the impeller pump of the hydraulic gear pump to prevent energy loss due to throttling problems, which are related to the control valve.
By analyzing the affinity law and pumping curve, the degree of impeller dressing is determined. These factors provide insights for analyzing the success of impeller dressing in optimizing energy consumption.
6. Implement control valves
The implementation of control valves is essential for controlling pressure and flow. For example, control valves help prevent energy losses caused by irrigation systems.
Generally, the control valve adjusts the bypass and throttling flow. By bypassing the water flow to the storage tank, the overpressure can be minimized, thereby optimizing energy consumption.
7. Maintenance of hydraulic gear pump
Maintenance assistance is essential to ensure continuous energy efficiency. During the maintenance process, technicians will find any deterioration that affects efficiency.
Examples of deterioration that unnecessarily increase energy consumption include rotor corrosion and wear ring corrosion. Maintenance work involves the application of lubrication to reduce friction, which is the main cause of energy inefficiency.
Another efficiency problem that needs to be solved in routine maintenance is pollution. Routine maintenance can reduce equipment failures that cause downtime. In addition to energy inefficiency, downtime is another costly issue for industrial and manufacturing facilities.
