Working principle of squeeze hose pump:
When the motor drives the rotor body to rotate through the reducer, the sliding extrusion roller on the rotor body rotates along the hose, and the joint action of the roller and the pump body will flatten the soft part. Return to its original state under action.
Designers and users of peristaltic concrete pumps value first and foremost its ability to transport strong abrasive media. It has no valves and no seals, and the only part in contact with the media is the inner cavity of the rubber hose, and the rotor of the compression hose is completely independent In addition to the medium. In addition, the peristaltic squeeze hose pump has many unique features: no other pump has better self-priming ability than the peristaltic pump, which can almost generate a perfect vacuum to absorb liquid; transport gas liquid, foam liquid And there is no air resistance; conveying high viscosity and shear sensitive medium is also a strong point; the fixed displacement per revolution has nothing to do with the outlet pressure, it is a natural metering pump. Various advantages make peristaltic pump more and more widely used in gold smelting, Non-ferrous smelting, chemical industry, mining, food processing, brewing, ceramics, water treatment and other industries.
Advantage of squeeze hose pump for pumping lightweight concrete:
1. Squeeze hose pump to pump the lightweight concrete with two-way equal flow delivery capability;
2. It will not cause damage to any part of the pump under the condition of dry running without liquid;
3. Can produce up to 98% vacuum;
4. There are no valves, mechanical seals and packing seals, so there are no factors for leakage and maintenance; it can easily transport solid, liquid or gas-liquid mixed phase fluid, allowing the diameter of the solid contained in the fluid to reach 40% of the inner diameter of the tubular element;
5. It can transport all kinds of materials with grinding, corrosion and oxygen sensitive characteristics and various foods;
6. Only the hose is the part that needs to be replaced, and the replacement operation is extremely simple;
7. Except for the hose, the conveyed product does not come into contact with any parts.
Squeeze pump for pumping lightweight faom concrete is precisely because of its unique performance in design. When it is conveying, in addition to the above-mentioned lightweight faom concrete medium, it is also suitable for some high-viscosity media. It can achieve good transportation. In fact, for the medium with high viscosity, ordinary pumps can't achieve good transportation, but this kind of peristaltic squeeze hose pump can achieve better working performance. It has a great deal of flow Good performance, so naturally it has been chosen by many users. In fact, its biggest advantage is not simply in terms of high flow rate, it has a good performance in terms of pressure. It can achieve high pressure at the same time. Very good head, and this is also a fundamental requirement in many industries. Now it can be widely used in industry because it has these two advantages.
1. The peristaltic squeeze hose pump is a volumetric peristaltic pump. The flow rate of the pump is determined by the output speed of the drive device. Due to the structure and material limitations of the pump, the speed is not easy to be too high, and its maximum speed should be less than 50 rpm.
2. When the process is in continuous operation, the actual flow rate should match the rated flow rate of the pump. If stable operation is required and the flow rate requirement is changing, it is best to choose a pump with adjustable speed, and the maximum flow rate should not exceed the rated rate of the pump. flow.
3. When the process is intermittent operation and there is no quantitative requirement, the rated flow of the pump can be greater than the actual required flow. If there is a quantitative requirement, the rated flow of the pump should basically match the actual flow. If the actual flow of the pump is greater than The required flow can be adjusted by adding a bypass pipe.
4. The rated pressure of the pump refers to the working pressure of the pump with a certain power motor. The actual working pressure of the pump is determined by the pipeline resistance loss and lifting height of the system where the pump is located. Therefore, in operation, The actual working pressure of the system should be greater than the rated pressure of the pump.
5. The operating temperature of ordinary hoses is ≤100°C. Considering the heat generated by moving parts during operation, it is generally used for working conditions where the material temperature is ≤80°C; if the ventilation (or cooling) heat dissipation conditions are good, the material temperature is allowed To 100 ℃, if the material temperature is > 100 ℃, special heat-resistant rubber hose should be selected.
6. Since the pump is a peristaltic pump, it has a certain pulsation when conveying materials.
