Twin screw pump filling machine is a filling equipment that uses a twin screw pump as the core component for fluid transportation

The double - screw pump is an externally - meshed screw pump, which uses two mutually - meshed and non - contacting screws to pump liquid. One of them is the driving screw, which is driven by the prime mover, and the other is the driven screw, which is driven by the driving screw through the synchronous gear. The gap between the outer circular surface of the screw and the pump body and between the screws is as small as possible. The screw and the pump body, and between the screws form a sealed cavity with each other to ensure that the liquid can be stably transported and will not flow backward. When the screw rotates, the volume of the suction chamber increases and the pressure decreases. Under the action of the pressure difference inside and outside the pump, the liquid enters the suction chamber along the suction pipe. As the screw rotates, the liquid in the sealed cavity continuously and uniformly moves axially to the discharge chamber. Since the volume at one end of the discharge chamber gradually decreases, the liquid is discharged.

Double - screw structure: This structure makes the filling machine more stable when transporting liquid, without agitation or pulsation, and can maintain the original properties of the liquid and avoid excessive shearing, emulsification and other effects on the materials.

High - precision metering: It is usually equipped with high - precision metering devices, which can accurately control the filling volume to meet the filling accuracy requirements of different products. For example, in the food, pharmaceutical and other industries, the accuracy requirements for the filling volume are relatively high, and the double - screw pump filling machine can well meet this demand.

Diverse materials: According to different filling materials, components such as the pump body and screws can be made of different materials, such as stainless steel, cast iron, etc., to ensure the corrosion resistance and wear resistance of the equipment. For some corrosive liquids, such as chemical raw materials, pesticides, etc., corrosion - resistant materials need to be selected to ensure the service life of the equipment.

Adjustability: The filling speed and filling volume can be adjusted according to production requirements, with strong adaptability. Whether it is large - scale production or small - scale production, the production requirements can be met by adjusting the equipment parameters.

Food Industry: It can be used to fill various liquid foods such as sauces, fruit juices, and edible oils. For example, in the production of jam, the double - screw pump filling machine can accurately fill the jam into glass bottles or plastic bottles and maintain the texture and taste of the jam.

Pharmaceutical Industry: It is suitable for filling various liquid medicines, oral liquids, eye drops and other drugs. Since pharmaceutical products have extremely high requirements for filling accuracy and hygiene, the double - screw pump filling machine can ensure the filling accuracy and meet the hygiene standards of pharmaceutical production at the same time.

Chemical Industry: It can be used to fill various chemical raw materials, coatings, paints and other liquid chemical products. These products often have relatively high viscosity or corrosiveness, and the double - screw pump filling machine can stably transport these materials.

Daily Chemical Industry: It is used to fill daily chemical products such as shampoo, body wash, and laundry detergent. In the production of daily chemical products, a large number of filling operations are required. The high efficiency and high precision of the double - screw pump filling machine can improve production efficiency and product quality.

Strong self - priming ability: There is no need for a special self - priming device, and it can suck in liquid by itself, which is very suitable for some occasions where the liquid level is low or liquid needs to be extracted from the bottom of the container.

Dry - running characteristics: The moving parts do not contact each other during operation, and short - term dry - running will not damage the pump elements, which provides great convenience for the automatic control process. However, the dry - running time generally should not be too long.

Low maintenance cost: The structure is relatively simple, the operation is reliable, the maintenance is relatively easy, and the service life of the equipment is long, reducing the maintenance cost and equipment replacement cost of the enterprise.
