Manufacturer of RR type rotary blower
Standard type RR-V pumps and dry type RR-V pumps are widely used in electric power, petroleum, chemical, fertilizer, steel, metallurgy, oxygen generation, cement, food, textile, paper making, dust removal, aeration, hydroponics, waste water treatment, pneumatic transportation and so on. The transported medium is fresh air and for other flammable, explosive and toxic special gases, they should be reported in order.
Main advantage
The wide airflow, pressure, discharge range and wide application range allow the customer to choose the most suitable fan.
Simple structure and easy to maintain.
Equipped with a new drive coil, excellent sealing, high efficiency, and energy saving.
The main components feature high machining precision to ensure good performance, stable operation and long service life.
The transported medium is oil-free, and no lubrication is required inside the cylinder during operation.
Operating requirements
The inlet temperature of the transported medium should not exceed 40 degrees Celsius.
The impurity content in the medium should not exceed 100 mg/m3, and the maximum particle size should not exceed half the minimum clearance.
During operation, the bearing temperature should not exceed 95 degrees Celsius, and the lubricating oil temperature should not exceed 65 degrees Celsius.
The operating pressure must not exceed the specified pressure rise range listed on the nameplate (or performance table) of the blower or vacuum pump.
The clearance between the impeller and the drum, the impeller and the side plate, and the impeller and the impeller itself must be properly adjusted before leaving the factory. This clearance must be ensured during reassembly (excessive clearance affects the blower's performance; insufficient clearance leads to friction or impact caused by thermal expansion).
The oil level in the main oil tank and the secondary oil tank must be between two red lines of the oil gauge while the blower is running.
Performance range
The blower's performance range is referred to in Table 5. The flow capacity shown in the table is the suction flow capacity, provided the air is clean under a standard atmospheric pressure of 101.325 kPa and an inlet temperature of 20°C.
The performance range of the vacuum pump is referred to in Table 6. The flow capacity shown in the table is the suction flow capacity, provided that the air is clean under a standard atmospheric pressure of 101.325 kPa and an inlet temperature of 20°C.
Note: When using a blower or vacuum pump to transfer special gases other than fresh air, the incoming airflow must be diverted according to the molecular weight of the medium being transferred, the incoming temperature, and the incoming pressure.
