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.

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. Operation and operation: A. remove the dirt around the machinery and equipment that endangers the safety of the machinery and equipment and the actual operation staff. B. before driving, fill the imported rotor pump with liquid to be transported (if the pump is on suction), open the inlet valve, close the outlet gate valve, and connect the power supply. C. connect the power supply and check whether the pump operation is proper. D. several test run for 3-6 minutes. If there are five abnormal conditions, the fund can be put into operation. F. during the first start-up after long-term shutdown or pump maintenance, remove the cooling fan cover of the motor and manually switch it off to check whether the rotation of the acid-base resistant magnetic pump is flexible. After confirming that there is no problem, install the cooling fan cover. 2. All normal parking: first turn off the gate valve at the exit, and then turn off the power. 3. Emergency braking: stop the motor immediately, and then close the outlet valve and inlet valve. 4. Overhaul and maintenance A. regularly maintain the pump and motor, and remove and replace the vulnerable parts. b. When long-term shutdown is not needed, high pressure should be used to clean the flow passage in the pump and disconnect the power supply. c. International air transport is prohibited. 5. Common problems in operation A. pay attention to the pressure difference between the front and back of the filter device at the suction end. When the pressure difference rises, it indicates that there is dirt blocking on the filter device. Stop the operation of the pump to facilitate the cleaning of the coarse filter. B whether the discharge volume and working pressure meet the standard value.
