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.

*Coatings: Paints, coatings, inks, insulating paints, resins, additives, organic solvents, etc.

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.

During the whole operation process of the sludge rotary pump, the maximum power of the motor and the operation of the pump should be paid attention to. If any abnormality is found, the pump should be stopped to search for the cause. The mechanical seal shall be free of leakage and heating. For pumps with rotating hydraulic seals, 1 to 3 drops per minute is allowed. If the leakage expands, just slightly tighten the material ring without disassembly. When the rotor pump in Ningbo adopts the industrial equipment CVT, the speed will be adjusted slowly according to the transmission ratio displayed in the data information after starting up. It is strictly forbidden to turn off the rotating speed plate of the equipment, otherwise the stepless reducer will be damaged. The soft starter can be used to adjust the speed of the radio station and the automatic control system. Check the heating of pump and motor frequently. When the price of roller rotor pump is in the condition of cooling circulating water, the temperature of roller bearing is raised to 40 ℃. When the pump is in boiling water heat insulation, the spherical bearing temperature is allowed to be 30 ℃ higher than the pump body temperature. In order to avoid the vibration of the pump caused by cavitation, the shut-off valve of the inlet pipeline can not be used to regulate the flow of the rotary pump in Ningbo. When the pump is in operation, it is strictly forbidden to close all the inlet and outlet stop valves. When the pump must be stopped, stop the pump and close the international trade valve, so as to eliminate the easily coagulated raw material sewage. After the pump is out of service for a long time, you should be good at rotating the coupling before opening it. You can feel the friction in your hand, but you can rotate it at will, light and heavy. And pay attention to identify whether there is friction sound and unclean things in the pump.
