15、 Piston pump

The reciprocating action of the piston inside the cylinder causes the cylinder volume to repeatedly change, in order to suck in and discharge fluid.

Performance characteristics:

Piston pumps, also known as electric reciprocating pumps, are divided into single cylinder and multi cylinder structures, characterized by high head. Suitable for transporting oil emulsions without solid particles at room temperature. Used for water injection, oil injection, and oil recovery in oil fields and coal seams; The power pump of the chamber press and hydraulic press, hydraulic sand cleaning, and ammonia liquid transportation in fertilizer plants. If the overcurrent component is made of stainless steel, corrosive liquids can be transported. In addition, depending on the different structural materials, it can also transport high-temperature tar, mineral mud, high concentration mortar, high viscosity liquids, etc.

Piston pumps are suitable for high-pressure and low flow applications, especially when the flow rate is less than 100m ³/h and the discharge pressure is greater than 9.8 megapascals, which demonstrates their high efficiency and good operating performance. It has good inhalation performance and can suck liquids of different media and viscosities. Therefore, it is widely used in the petrochemical industry, machinery manufacturing industry, papermaking, food processing, pharmaceutical production, and other fields. Low to medium speed piston pumps have low speeds and can be operated manually or dragged by animal power, making them suitable for rural water supply and small-scale irrigation.
