Are SiC Ceramic Pumps environmentally friendly?
With today's low-carbon economy era, the entire industry is seeking ways to reduce carbon emissions solution.
Pump manufacturer also focuses on eco-friendly composite materials.
SiC Ceramic Pumps are designed to minimize energy consumption and reduce waste, making them an eco-friendly choice for sustainable industrial operations.
The energy saving and consumption reduction of silicon carbide ceramic pump are mainly reflected in:
- 1. The full vacuum casting process, reduce the amount of metal materials, more energy saving than traditional metal casting, and less pollution.
- 2. Through the optimization of pump performance design, pump efficiency improvement play a role in energy saving and consumption reduction effect.
- 3. Long service life, reduce downtime and operating costs, that is, save human and material resource.
Measures and Methods of Reducing Cavitation
When vacuum of pump inlet is too high( namely, when the absolute pressure is too low), the liquid in the pump inlet would vaporize, resulting in cavitation.
If running under cavitation, the wet parts of the pump would be worn very quickly under the combined effect of cavitation and abrasion. In the case of serious cavitation, the pump will vibrate and make noise. Moreover,the pump may even could not run due to the sharp fall of head, flow capacity and efficiency. Cavitation does great damage to pump and should be avoided.
In order to prevent or reduce cavitation, not only the producer should improve the design and manufacturing, but the users should take planning, design and operation management of the pump station into consideration. To avoid cavitation, the available net positive suction head(NPSHa) must be raised , making it exceed required net positive suction head NPSHr . Measures could be taken as follows:
- 1). Reduce the geometry suction height(for suction installation pumps), or increase the geometry back flow height(for back flow installation pumps)
- 2). Reduce suction loss by increasing pipe diameter or decreasing pipe length, elbow and accessories, etc.
- 3). Prevent long time running under large flow capacity.
- 4). Under the same rotation speed and flow capacity,it is better to adopt double-suction pump which could decrease inlet velocity and avoid cavitation.
- 5). When cavitation appears, please turn down the flow capacity or lower the rotation speed.
- 6). The condition of pump suction tank has important impact on the cavitation.
- 7). For the pump running under harsh conditions, cavitation resistant materials could be used to prevent the damage of cavitation.
What is TDH?
TDH=Total dynamic head= Static Height + Static Lift + Friction Loss. It is comprised of two parts: net head(static head) and head loss. Usually specified in either inches or meters.
Where:
Static Height is the maximum height reached by the pipe after the pump (also known as the 'discharge head').
Static Lift is the height the water will rise before arriving at the pump (also known as the suction head).
Friction Loss(head loss) is the loss of energy or ‘head’ that occurs in pipe flow due to viscous effects generated by the surface of the pipe which includes energy lost due to obstructions.
