Understanding the Working Principle of Vacuum Self-Priming Pumps
Types of Vacuum Self-Priming Pumps1. **Self-Priming Sewage Pumps with Auxiliary Vacuum Systems**
These pumps can be categorized into two main structures:
This heat can affect the performance and longevity of the pump.
– **Self-Priming Sewage Pumps with Auxiliary Vacuum Systems:** These systems utilize an additional vacuum mechanism to enhance self-priming capabilities.
2. **Combination-Type Vacuum Self-Priming Sewage Pumps**
This category includes two structural designs:
– **Integrated Self-Priming Pumps with Clutch Mechanisms:** These pumps combine a centrifugal pump with an electromagnetic clutch and air intake/exhaust mechanisms.
– **Combination Self-Priming Pumps with Vacuum Impellers:** These pumps integrate a horizontal centrifugal pump with a water ring vacuum pump.
Detailed Analysis of Pump Types
1. **Diesel engine Vacuum Self-Priming Sewage Pumps**
– Upon powering the diaphragm pump, a vacuum is created in the inlet pipeline and pump chamber.
– Atmospheric pressure forces the medium into the pump chamber.
2. **Integrated Self-Priming Sewage Pumps with Clutch Mechanisms**
This type of pump comprises a centrifugal pump combined with an electromagnetic clutch and an air intake/exhaust mechanism. The operational process is as follows:
– An eccentric gear connected to the bearing housing expels air from the inlet pipeline, achieving self-priming.
– Once the control system detects that the medium has entered the pump body, it disengages the clutch, allowing the centrifugal pump to function normally.
3. **Combination Self-Priming Sewage Pumps**
This type features a horizontal centrifugal pump paired with a water ring vacuum pump. The operational mechanism includes:
– A vacuum chamber positioned behind the centrifugal pump cover, with the vacuum impeller aligned coaxially with the centrifugal pump impeller.
– The pump uses an external flushing water source, which does not require high pressure—ordinary tap water suffices.
The operational steps are:
– The flushing water enters the vacuum chamber through the mechanical seal wash port.
**Advantages:**
– Simple structure and lower cost.
– No need for liquid priming, rapid self-priming capability, and a self-priming depth of up to 8 meters.
Conclusion
Understanding the various types and their working principles allows for better selection based on specific operational needs and conditions.
