Description

Technical Field

[0001] The utility model relates to the technical field of plunger type metering pumps, and more specifically to a high-safety plunger type metering pump. Background Art

[0002] A plunger metering pump is a pump used to accurately measure liquids. It delivers liquids at a precise flow rate through the reciprocating motion of the plunger. This pump is usually used in situations where precise control of flow and pressure is required, such as chemical production, water treatment, and pharmaceutical production.

[0003] Plunger metering pumps are usually used to transport chemicals or corrosive liquids. Therefore, they need to be maintained regularly to ensure that all parts of the pump are in good condition to avoid safety problems caused by equipment failure. When repairing the metering pump, the pipeline needs to be disassembled before repair, which is cumbersome and increases the difficulty of repair. The prior art discloses a plunger metering pump with a built-in safety valve, and the utility model patent with application number CN202022780494.3. By setting a safety valve and a buffer, the safety valve can ensure the safe operation of the plunger metering pump and the safety of the pipeline system. At the same time, during maintenance, the pipeline can be closed through the safety valve, so that the metering pump can be disassembled and repaired without disassembling the pipeline, which is convenient for maintenance. In addition, the buffer can also reduce the pulse of the output liquid and improve the safety of use. However, when it is in use, the height and angle of the metering pump cannot be adjusted, which makes it inconvenient to use. Utility Model Content
