Product introduction:

The rotary Lobe Pump is a kind of positive displacement pump. There is a pair of synchronous counter rotating cams in the pump cavity. Hollysys fluid technology has always been committed to combining the product with practical application, continuously upgrading and improving the product. According to years of research and experience accumulation, it has determined a series of rotor pumps under different working conditions: chemical type, food type, general type, etc When conveying different media, the product adopts the corresponding configuration, which makes the rotor pump play the characteristics of stability, efficiency and safety in a variety of different application conditions, and provides the majority of users with the solution of fluid transportation in line with the requirements of the actual working conditions.

working principle:

When the two rotors rotate in the opposite direction synchronously, the volume cavity periodically changes from small to large - from large to small to achieve the purpose of conveying fluid. The flow rate of the pump depends on the volume of the working chamber and its changing frequency in unit time, but (theoretically) has nothing to do with the discharge pressure; Driven by the transmission shaft, two rotors (rotor blades are 1-8) rotate in the opposite direction synchronously. In the process of rotation, the volume at the inlet increases from small to large to produce suction (vacuum degree) to absorb materials. After that, the two rotors and the pump cavity form a fixed volume cavity, and the volume at the outlet of the pump decreases from large to small to output materials, forming a higher vacuum degree and conveying pressure.

Product features:

There is a certain gap between the rotor and the pump body, between the rotor and the rotor, no contact, no friction, long service life.

No need to dismantle the pipe, open the pump cover to repair, convenient maintenance and cleaning, less vulnerable parts.

Low energy loss, high efficiency, low failure rate, reliable sealing and low noise. It can transport high viscosity, high concentration, containing soft solid particles and other materials with poor fluidity.

The output flow of the pump can be changed within a certain range by adjusting the pump speed, and can be used as a general metering pump.

It can be equipped with flange type, screw type, clamp type and other types of connection, and the in and out direction can be horizontal or vertical.

It can transport gas, liquid and solid mixed materials and transport a wide range of materials. Built in thermal insulation cooling structure design, good thermal conductivity, easy installation. It can be equipped with sanitary safety valve and pump valve, and the pressure overload protection of pipeline system is simpler.

The rotor and pump cavity can transport the medium containing solid particles such as sludge and sewage after using special materials and technology.

Compared with centrifugal pump, the total flow of rotor pump can be controlled accurately. The total output flow of centrifugal pump can not be accurately controlled, and it will decrease with the increase of friction resistance. Rotor pump has a strong self-priming capacity, and centrifugal pump must be filled with liquid before moving. With the increase of viscosity, the total flow of centrifugal pump decreases and the output power increases; On the one hand, with the increase of viscosity, the internal leakage decreases, the capacity efficiency increases, and the total flow increases, which improves the efficiency of the pump and reduces the output power. On the other hand, with the increase of viscosity, the liquid friction increases, which correspondingly reduces the efficiency of the pump and slightly increases the function loss. But in a word, it transports a large viscosity liquid, The efficiency of rotor pump is gradually improved. The rotational speed ratio of rotor pump is generally low, generally between 200R / min and 400R / min. the raw materials transported are output stably, and their components are not easy to be damaged; The centrifugal pump has some efficiency under the special speed ratio, and the raw materials are subject to super strong impact and centripetal force. Therefore, when the centrifugal pump transports compounds, the chemical composition is often different, which reduces the quality of the finished products. Rotor pump is just the choice to deal with this problem, so it is especially suitable for conveying mixed materials and even raw materials with solid particles. Rotor pump can be used to transport chemical substances with high viscosity. But the centrifugal pump does not have the characteristic. Rotor pump can be easily made into the type of high output working pressure, suitable for long-distance or high friction resistance quantitative analysis of transportation.
