Abstract

The invention provides a novel metering pump, and relates to the technical field of liquid supplying devices. The novel metering pump comprises a power device (1), a crank and connecting rod mechanism (2), a piston (3), a pump body (4), a one-way liquid inlet valve (5), a liquid inlet pipe (6), a one-way liquid outlet valve (7) and a liquid outlet pipe (8), wherein the power device (1) is connected with the upper end of the crank and connecting rod mechanism (2), the lower end of the crank and connecting rod mechanism (2) is connected to the middle of the piston (3) which is arranged in the pump body (4), and both sides at the lower end of the pump body (4) are respectively provided with the one-way liquid inlet valve (5) and the one-way liquid outlet valve (7) which are respectively connected with the liquid inlet pipe (6) and the liquid outlet pipe (8). The novel metering pump has the advantages of simple, scientific and reasonable structure, reduction of manufacturing cost, easiness in maintenance, convenience and rapidness in flow regulation, easiness in operation and high supplying metering precision.

Description

Technical field: [0001] The invention relates to the technical field of liquid conveying equipment, in particular to a novel metering pump. Background technique: [0002] The metering pump is a special positive displacement pump that can meet the needs of various strict technological processes. The flow rate can be adjusted steplessly within the range of 0-100%. It is used to transport liquids (especially corrosive liquids). Metering pumps are also called quantitative pumps or proportional pumps. They belong to reciprocating volumetric pumps and are used for precise metering. Usually, the stability accuracy of metering pumps is required to be no more than ±1%. With the continuous development of modern industry towards automatic operation and long-distance automatic control, the advantages of metering pumps, which are well matched and adaptable to a wide range of media (liquids), are particularly prominent. [0003] The existing metering pump drives the worm through the moto...
