Cam rotor metering pump

‌Cam rotor metering pump, also known as colloid pump, three leaf pump, sole pump, relies on two rotors (2-4 teeth) rotating synchronously and reversely to generate suction (vacuum degree) at the inlet during rotation, so as to absorb the materials to be transported. RockySea petro can produce the high-quality cam rotor pump for metering to meet the requirements of different application scenarios.

DESCRIPTION

Working principle

During operation, the cam rotor pump of RockySea petro is to take the twisted rubber cam rotor pump as the core, and use two spiral cam rotors driven by synchronous gears to push the transmission medium from the pump inlet to the pump outlet. Because of the perfect sealing between the rotor rubber impeller and the pump body, the pump inlet and outlet chambers are completely separated, with strong vacuum pumping capacity. Therefore, the self-priming capacity of the pump is far greater than that of other types of pumps.

Since the three blade 60 ° spiral rotor is adopted, the instantaneous design flow of the pump is constant at every moment during the rotation cycle, with almost no pulsation and disturbance. The structure of RockySea petro cam rotor pump is completely symmetrical, and the delivery direction is reversible. Just change the driving direction, positive transmission suction and reverse rotation can be used for flushing.

TECHNICAL DATA

Technical Feature

RockySea petro cam rotor metering pump has the following features.

1. Gas liquid two-phase sealing technology: special mechanical seal developed by famous domestic mechanical seal experts is adopted. The sealing surface has unique structure, sufficient lubrication, no air resistance, and sufficient convection of cooling medium, which can effectively prevent dry grinding, high temperature, cracking, and failure of the sealing surface, and ensure the normal operation of the pump unit.
2. The pump rotor adopts composite wear-resistant rubber rotor, and the pump body is solid, durable and has a long service life;
3. The gas-liquid adaptive integrated box can effectively eliminate the air resistance and cavitation in the process of air extraction (100 meters of self-priming), so that the pump device has the functions of gas transmission and infusion of pumps and compressors at the same time.
4. Strong traffic cability: ordinary plastic bags, woven bags, sand and gravel, mud, hair and other sundries will not affect the use of the pump.
5. Integrated control system: the project adopts advanced embedded system to develop intelligent control system to realize intelligent monitoring.
