Analysis of the advantages and disadvantages of hose pumps
1. Advantages of hose pump: Simple and quick cleaning and disassembly. Since the medium only flows in the hose, cleaning is only for the hose, and the hose pump hose is relatively simple to install and remove. As long as the motor is started, the installation and disassembly operations can be completed. The medium conveyed by the hose pump is not in contact with the pump body, which is conducive to conveying some media that are corrosive to metals, such as various acid and alkali solutions, or some salt solutions containing chloride ions. .Speed u200bu200band flow can be controlled. The speed of the motor for hose pump is not high after being decelerated by the reducer, and the maximum speed generally does not exceed revolutions per minute. In addition, the selection of the motor can adopt manual speed regulation and frequency conversion speed regulation to better control the flow. . The conveying speed is slow and the noise is low. . The hose pump has good durability-suitable for various industrial or laboratory conditions. . Good self-priming function-no siphon, dry flip and self-priming. . When the hose pump is blocked at the inlet and outlet, the blockage can be turned upside down to protrude. . The shearing force is very small and will not destroy the medium state. Since the pressure roller squeezes the hose from the tangential direction, the speed is slow, and it has a unique advantage in conveying some sensitive and easily damaged media. 2. Disadvantages of the hose pump: The pressure limit of the hose pump: The pressure will be limited by using flexible pipes. . The pump generates pulse flow when it is working. The solution is to use a pulse suppressor. The pulse suppressor is a simple positioning container. The working principle is that air is more compressible than liquid. The pulse stream enters the container, the air bag on the liquid sinks to absorb the pulse, and then flows out of the pulse suppressor smoothly. .Under the same flow rate, the weight and floor space of the hose pump are relatively large. The rubber hose of the hose pump is limited by temperature, and the maximum temperature does not exceed ℃.
