Pump traps



Video introduction

Pump traps use the trap principle, relying on steam, air and other gases as power to transport condensate from the low pressure area to the high pressure area, or from the negative pressure area (vacuum) to the normal pressure area. The condensate recovery pump has a series of advantages such as automatic control, no cavitation, simple maintenance, no electricity, water hammer resistance, large displacement, explosion-proof, no noise, and the pressure of the power steam determines the head. It is unmatched by other electric pumps. It is widely used in the recovery of steam condensate and the transportation of low-viscosity non-volatile liquids.
working principle
The pump trap has two strokes:
Inlet water and exhaust steam: At the beginning, the inlet check valve is opened, and the outlet check valve is closed due to high back pressure. At the beginning, the water inlet and exhaust valves in the valve are opened, and the float is in a low position. As the water level rises, the float When reaching the highest, the controller is in the state of switching zero boundary.

Inlet steam and drainage: the controller starts to switch at a high position and closes the exhaust valve; opens the power steam, injects steam into the valve, and pushes the condensate in the pump to the high pressure area under the push of steam pressure, then the inlet check valve Due to the high pressure inside the valve, water cannot enter. When the float reaches a low position, the controller switches to close the power steam, opens the exhaust valve, and enters the next action cycle.
Structural features

Its not driven by electric power, driven by steam or compressed air, is explosion-proof and safe, and can be used in any environment。
The structure is compact, and there is no requirement for installation, Even in the wild, it will not affect its normal operation.
Automatic control, the amount of water output is determined by the amount of water input. When the amount of condensed water increases, the working frequency speeds up, when it decreases, the working frequency decreases, and no condensed water enters and stops working.

No cavitation work, completely overcome the shortcomings of electric pump cavitation
All stainless steel internal parts and special materials guarantee performance and life
