LD vertical roots blower
L series Roots blower and roots vacuum pump are the earliest roots blower series products jointly designed by the Ministry of machinery in 1987 in China. They have a history of more than 20 years. At the same time, according to the market information and various valuable opinions from users, the products have been revamped for many times, so that the L series Roots blower and roots vacuum pump produced by our factory have better performance and reliable operation It fully meets the needs of various working conditions and media, and forms its own product characteristics.
2. Main features:
1. The pressure changes with the change of the positive force of the system, which is adaptive.
2. Hard exhaust with forced air supply. When the pressure changes, the flow rate changes little.
3. The conveying medium does not contain oil.
4. The flow is classified into dense grades, covering a wide range, which can be widely used by users. 0 sealing forms are various, which can meet the needs of different media. O variety of specifications, including vertical, horizontal, positive pressure, negative pressure.
5. Advanced structure. Reliable operation, long service life and convenient operation and maintenance.
3. Main uses:
It is widely used in electric power. Petrochemical industry. Chemical fertilizer, iron and steel, smelting, oxygen production, cement, food, textile, paper, dust and back blowing, aquaculture, sewage treatment, pneumatic conveying and other sectors.
4. Description of performance table:
The flow in the performance table of digital fan refers to the inlet flow when the suction pressure is standard atmospheric pressure (101 325kpa a). The suction temperature is 200, the relative humidity is 50%, and the conveying medium is pure air. The flow rate in the performance table of vacuum polymerization (negative pressure blower) refers to the flow under each inlet vacuum degree when the suction temperature is 200, the relative diffuse degree is 50% and the pumping medium is pure air. If not, conversion should be made.
V. ordering instructions:
(1) when ordering, it should be noted: conveying medium. Inlet pressure. Inlet temperature, inlet flow, pressure rise, environmental conditions and whether there are special requirements. (2) Standard matching host, coupling and base (if any). Anchor bolts.
(3) optional accessories (as required by the contract): muffler, air filter, pressure relief valve, electric actuator, inlet and check valve, elastic joint, silencing elbow, silencing pipeline, etc.
There are 11 models of l21ld; l22ld; l23ld; l23ld; l41ld; l42ld; l52ld; l53ld; l62ld; l63ld.
Conclusion: LD series Roots blower is a vertical structure two blade roots blower, which is also the first batch of independent research and development products in China. Although this structure of Roots blower is gradually replaced by three leaf structure, its performance is not inferior to that, and it also occupies an irreplaceable leading position in the previous industrial market.
