Lubricant performance of peristaltic pump

Release date:Mar 01, 2023 Source:PreFluid Pageviews:-
Peristaltic pump tube is in peristaltic state when working, so it is called peristaltic pump. The peristaltic pump rotor compresses the elastic hose and remains sealed before and after the pressure point.
Peristaltic pump tube is in peristaltic state when working, so it is called peristaltic pump. The peristaltic pump rotor compresses the elastic hose and remains sealed before and after the pressure point. When the pressure wheel rotates, the pressure point on the hose moves accordingly. Because the hose is elastic, when the pressure wheel leaves, the hose on the inlet side of the pump naturally rebounds, and the inlet pipe produces negative pressure and inhales liquid. With the continuous rotation of the peristaltic pump rotor, the fluid in the hose is discharged continuously.

Peristaltic pump has the following characteristics and advantages:.

Clean: Pumped liquid only through the hose, does not pollute the pump body. Different tubes can be used to transport different liquids.

Accuracy: Flow can be accurately controlled and adjusted.

Self-priming characteristics: no need to pump primer, dry operation.

Globe valve characteristics: the pressure point of the peristaltic pump runner makes the hose always in the cut-off state, with the function of the globe valve.

Possibility of positive and negative rotation: change the direction of the motor, can realize the change of the direction of transmission, convenient to achieve positive and negative rotation and suction back.

No shearing: Fluid transfer in a peristaltic pump is achieved through the peristaltic movement of the hose, so the fluid in the tube is not shearing.

The peristaltic pump consists of three parts: the driver, the pump head and the hose. Products are widely used in chemical industry. Mining and metallurgical industries. The paper industry. Paint industry. The food industry. The ceramic industry. The petroleum industry. Water treatment industry. Pharmaceutical and instrument industries. Home appliance industry.

The hose should have good resilience, the pressure points should be sealed back and forth, and the liquid should move forward. The drive needs to be low noise and long life. Peristaltic pump hose and driving gear are more susceptible to friction and corrosion, so do a good job of peristaltic pump lubrication is economical and effective.

1. Hose lubrication:.

The lubrication of this part is mainly due to its good compatibility with the hose, good lubrication effect, good wear resistance, hose after a few hours of life test without cracking phenomenon. It needs to meet the following criteria:.

1.1. Suitable for the ambient temperature of -40 °C to 60°C.

1.2. With good compatibility with rubber material, grease must pass strict rubber compatibility test, and there is a test report.

1.3. Excellent antioxidant and aging resistance.

1.4. Some have food grade requirements.

2. Gear lubrication :.

The drive gear box is usually of planetary gear construction. Different applications, worm gear and worm materials are different, also need lubrication. The influence of current, noise, temperature rise and life span are several important factors to be considered. The lubrication of peristaltic pump needs to meet the following indicators:.

2.1. Good noise reduction effect.

2.2. The current has little influence.

2.3. Lubricants do not evaporate.

2.4. Excellent antioxidant and aging resistance.

2.5. Good lubrication performance.

2.6. Strong adhesion.
