    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.

     

    Application fields:

    *Daily chemical: detergent, washing liquid, shower gel, skin care cream, shampoo, hand sanitizer, toothpaste, soap, detergent slurry, daily chemical raw materials, etc.

    *Fine chemicals: dyes, pigments, adhesives, silicone oil, leather oil, chemical additives, various colloidal materials, various sizes, etc.

    *Food: chocolate, condensed milk, yogurt, honey, syrup, sucrose, tomato juice, concentrated fruit juice, jam, ice cream, milk, yeast slurry, pulp, jelly, condiment, distiller's grains, soybean protein, flour slurry, etc.

    *Papermaking: polyacrylamide (PAM), gelatinized starch, carboxyl styrene butadiene / styrene butadiene latex, rosin, rosin size, filler, dry strength agent, wet strength agent, sizing agent, retention and drainage aid, defoamer, coating, water treatment chemicals, etc.

    *Chemical fiber: viscose pulp porridge, PVA, vinylon size, acrylic size, polyamide size, polyester chip, polypropylene, man-made fiber, functional fiber, etc.

    * medicine: all kinds of ointment, extract, medicine emulsion, pill paste, syrup, health products, medicament and so on.

    *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.

    1、 How to repair the pump when it cannot be started: 1. The valve core is seriously worn and stuck. 2. The shaft coupling is worn out. At this time, the shaft sleeve should be removed. 3. The screw rods on both sides of the central shaft fall. 4. It's the rupture of both layers of pulse dampers. 5. Is the pneumatic diaphragm pump reverse or flat. Valve core can not return (first generation and second generation) 2. How to repair the low total flow: 1. The product (plastic ball) is worn out in import and export trade. When a flocculent, big grain stuck plastic ball. The copyright notice of the control engineering network of the liquid geothermal well at the feed hole during the feeding and suction is issued, and the raw materials are almost pressed back at the feed hole during the feeding. 2. The diaphragmatic film is often ruptured, leading to small volume of raw material cavity. The third is gray black, the thick layer of pulse damper is damaged. When the center axle is pushed, it doesn't go well. 3、 The posture of heat-resistant cam pump is very slow, and the casing speed is relatively slow. I don't like how to repair it: 1. The standard pressure of steam source is reduced. Take a look at the pressure of the near gas pressure gauge first, and the pressure value is 4-7kg, so there is no problem. Then check the opening position of the steam source cutting door. If the steam source is opened or closed by relay, check whether the relay plastic part pump shell is damaged, and the plastic part pump shell cannot be completely opened. 2. Because the muffler is blocked, the air can not be discharged quickly, and the speed of the guide sleeve is relatively slow. 3. It's too much water or residue compressed by air. After entering the valve of pneumatic diaphragm pump, block the air inlet and outlet, or block the valve core. 4. Due to the impact of the valve core, the left and right bearing end covers of the valve often lead to the damage and leakage of the single flow valve. 5. The four sealing rings of the inner shaft of the pump were worn out and blocked.
