The type of Tara straightening machine speed improved the introduction of Fangwanian from American companies.
Actual production hall size. Some of the shortcomings in the design have been exposed. The profile casting machine is 3 casting streams. A 4-fold tensioner is used for each flow. When working, the mountain motor is driven. The worm gear reducer is manufactured by Cleveland, USA, and drives the squeezing roller to pull the slab out.
1 system is the continuous operation hall. The working environment temperature is high. Since its use in 1998. The reducer has suffered multiple damages in succession.
Reasons for damage to the reducer The damage to the reducer is the worm bearing and the worm wheel journal, because the reducer uses a traditional skeleton seal. Long-term work in high temperature environment, oil seal aging wear. The seal of the output shaft fails, the journal is ground, and the lubricating oil in the reducer is seriously lost. Since the stage-decelerating worm is in the vertical position, the upper bearing is lubricated by the lower vane pump cycle. After the dirt and abrasive material is sucked into the pump, the pump is damaged, so that the upper bearing is deficient in oil.
To solve the damage of the reducer, the lubrication and sealing of the reducer must be improved to replace the original skeleton oil seal, and the structure of the reducer is improved. The magnetic seal structure consists of 4 parts and 1 moving ring. The moving ring is an alloy ring embedded with a magnetic element, and the outer side is sintered and wear-resistant. Good lubrication of carbon and graphite. It is a clearance fit with the shaft.
It can maintain close contact with the static ring under the action of magnetic force for a long time and automatically compensates for wear. No manual adjustment is required.
Ten stability is good. Made of high-hardness wear-resistant alloy, the working surface is extremely smooth, warm and oil resistant and has good elasticity. It can be compensated well when the curtain is moving. It passes the machinery. Hold the square 0 circle. The joint surface of the shaft and the moving ring is sealed by the 0-ring taken by the material.
During work, it relies on the magnetic force between the static and dynamic rings to attract each other under the auxiliary action of the bellows. The friction surfaces are closely fitted to achieve a good sealing effect.

North Baoding City 071003 fee. 15 cost-performance 1 technology history new slow instrument cutting can be compared with single-portable mountain factory Beijing set Wang Qiding and other shortcomings, and is based on 18 interface to complete data acquisition, to improve the natural gas compressor unit lubrication system with notebook power â–¡ Chen Guiping B series natural gas compressor unit is Chengdu Natural Gas Compressor Factory introduced the technology of American Cooper Company, which is assembled from some domestic and imported parts. The power section of the unit is a natural gas fueled stroke engine. The root crankshaft is shared with the compression section. It is 180 symmetrically balanced. The compression section can achieve power matching of the engine by adjusting the clearance volume or working mode. It has the advantages of easy operation and large processing capacity, and is mainly used for supercharged mining in later gas fields. However, the unit has been fully loaded for a long time. There are some shortages in the lubrication system. The important transmission components of this series of compressors, such as the main bearing of the crankshaft, the connecting rod, the copper sleeve, the crosshead piston rod, etc., are splash-lubricated; the power
Cylinder compression cylinder packing is filled with oiler and pressure lubrication. 1. Pressure-lubricated High reliability.
While flying, the reliability of lubrication is relatively poor. The shank linkage mechanism pressure storage piston rod lubrication system exists on the site of the regular 2000 dynamic detection of crankcase lubricants, mainly high metal scrap content. Since the crankcase lubricating oil has no circulating filter device, the metal chips are deposited in the crankcase for a long time. Progress has accelerated the wear rate of components.
Start the unit in the winter when the ambient temperature is below 15. Due to the viscosity of the lubricating oil, the fluidity is poor. When operating at low speeds. The lubrication system cannot reliably lubricate the various sports auxiliary entrances. Easy to cause burns and strains.
Splash lubrication part. Can not meet the needs of the lubrication of moving parts of the 21 series compressor unit. If the crankcase oil level is low, the lubricating oil performance is low, and the low speed may cause poor lubrication of moving parts.
Improvement measures and benefit assessment measures. For the two lubrication modes of the compressor unit, the independence and the difference in lubrication effect are large. The unit uses two different cost-effective lubricants, and the crankcase uses high-quality lubricants Mobil Pegasus 705. The pressure lubrication system uses ordinary diesel engine oil, 30 Nanchong Jiali products. Execution standard, 201919152 2612004. Both guarantees efficient lubrication of splash-lubricated parts. It also reduces the cost of using pressure lubrication.
Take the 21265 unit as an example. Pressure lubrication fuel consumption 7300 fly per year lubrication oil consumption 4561 original two-part lubrication full-use ordinary diesel engine oil 50,000 days tons. The annual fuel consumption cost is 37,500 yuan. The annual cost of replacement of transmission parts is 155,000 yuan; 1 No 4705 type; slippery 25,000 tons, annual fuel consumption cost is 187,500. The cost of replacing the transmission parts is 10.
30,000 yuan. The comparison between the two shows that the Mobil Pegasus 705 type lubricant is used. Although the cost of parts consumption can be reduced, the total operating cost of the unit is increased. Two lubricants are used separately. The annual operating cost is about 202,000 yuan.
Measures. Adding a set of circulating filter packs is expected to extend the replacement cycle of crankcase lubricants. Annual savings of 2281 unit failure rate reduced by 0.
Measures. An additional electric heating system for the crankcase lubricating oil is used to start the machine when the ambient temperature is lower than 5, and to heat the lubricating oil of the front crankcase. It is estimated that the annual increase in the efficiency of the unit is far from about 801. W05.0323 garden editing Coli rJ, in view of the lower worm speed of about 25, the oil supply of the upper end of the original worm is changed to grease lubrication. Add a magnetic oil seal to the lower part of the bearing. Form a separate bearing housing. According to the installation requirements of the magnetic oil seal. Properly improve the end caps, first the end caps. The elastic element and the static ring are assembled with screws, and the surface is glued to ensure reliable seam sealing.
The journaled portion is smoothed to remove burrs. Push the moving ring anti-friction material outward from the shaft end into the appropriate position on the shaft. Do not fit in place and keep it straight when pushed in.
To prevent damage, the ring, the end cap elastic element and the static ring are loaded and pushed into the static ring. Push the moving ring to the working position. Ensure that the static and dynamic rings are closely fitted.
4 Check the fit between the static and dynamic rings. Make sure there are no impurities and gaps, and that the coaxiality is good. Drive the reducer to ensure no relative movement between the shaft and the moving ring.
After using a magnetic seal on the five tension reducers of the profiled caster, it has been in normal operation for 13 months. Eliminate the oil leakage of the reducer. From the perspective of long-term use. Magnetic oil seal can greatly reduce oil consumption and equipment maintenance costs, and has a high KjWfHfHl1I. W05.03 edited in Maanshan City, Anhui Province
Motorcycle Cylinder
it is the cylinder in an engine where the combustion takes place-..in bikes the cylinder is just above the transmission. think of it as a syringe. the piston moves up and compresses the air fuel mixture and as a result combustion takes place. the piston is then pushed down. this up and down motion of the piston rotates the crankshaft which is connected to the transmission which transmits power to the wheels. there are various configurations of cylinders in an engine. in bikes you have single cylinder, parallel twin, v twin, L twin, inline 4, inline 3, inline 6, v4, flat twin. similarly in cars you get inline 3, inline4, inline6 , v6, v8, v10, w12. the number represents the no. of cylinders and the letter or prefix represents the configuration.
