Jinan and blower

Jinan is and Construction Machinery Co., Ltd. was established in the 1980s, the company relies on strong scientific research strength and strong research and development capacity, rapid development and growth, has become Shandong Jianzhu University, teaching and experimental base Jinan Engineering Vocational Technical College, for our company Development ZHD, SZR, ZHL series Roots blower technology has laid a good foundation. In 2000, the company further improve scientific research, specially invited two experts to the National L series Roots blower joint design team to develop in the company ZHD series of high pressure blower, and invest a lot of manpower and resources. After three years of meticulous research, trial and error, and finally in 2003 successfully developed China's first high-pressure blower ZHD1-200. Luo The product under natural temperature conditions of 35 ℃, after 1450r / min high speed running eight hours with a load, boost reach 98.8kPa, the main fuel tank temperature does not exceed 80 ℃, become our country's first non-water-cooled, easy to use, energy-efficient Mainz blowers, high pressure air to fill the gaps in the cooling water; two new patents have been issued by national patent offices, three patents. In terms of energy saving and environmental protection to make its own contribution. Positive and high and low pressure turbine, pump has been serialized into the market. "Positive and" trademark in 2009 was named "Shandong famous trademark" honorary title. At the same time, I also developed a SZR, ZHL series Roots blower, up more than 10 models, more than 80 kinds of specifications. Fans of the series is small, air volume, low noise, smooth and reliable operation, with significant energy savings, in sewage treatment, pneumatic conveying, aquaculture, vacuum packaging, power desulfurization, Federated foundry industry plays a role in energy-efficient, become a highly by the users of the product. The company is located in the beautiful banks of Baimaiquan Zheshan Mingshui Economic Development Zone Industrial Park, covers an area of ??70,000 square meters, registered capital of 18 million yuan, has offices, catering, staff quarters, sports venues, which ensure that Good workers living and working environment. Qi, general manager of cattle more solemn promise: "we have to 'customer satisfaction first, reliable product quality, technology advances, product innovation, service and thoughtful' for the purpose, warmly welcome all the friends come to my company to discuss business, visit the guidance fault. Maintenance 1. Fan vibration severe ① fan shaft and motor shaft is not parallel to the pulley housing or dislocation ② impeller inlet and friction-based loose rivets ③ or ④ impeller impeller deformed or impeller loose rivet deformation ⑤ impeller shaft and the shaft with loose plate hole ⑥ leaves have fouling, dirt, abrasion or bending the shaft of the rotor imbalance ⑦ fan inlet and outlet pipe installation poor resonance ⑧ housing and bracket, bearing bracket, bearing and bearing cap bolts and other loose 2. The bearing temperature l too severe vibration ② ① bearing lubricant viscosity does not degenerate or contain foreign material, a lubricant filling inadequate or excessive bending or bearing ③ bearing damage, the bearing inner ring or outer ring too loose or too tight tolerances 3. Motor overcurrent ① large or rise too high to drive the inlet pipe is not tightly closed ② sent gas with viscous material ③ spindle speed exceeds rated ⑤ ④ bearing box severe vibration motor input voltage is too low or the current lack Item 4. belt beating or sliding By: belt wear, loose or lengthen the period over two pulley groove center line is not the same with each other.
