Equipment Management and Maintenance 2012No8 3. The oil content and fuel consumption in the exhaust gas are large. The oil content and fuel consumption in the exhaust gas are large. It should be noted that the oil level of the lubricating oil is guaranteed within the normal range. Clean or replace the return line. The loss of control of the oil return check valve causes the oil to flow back to the oil separator after the unit is shut down, which will cause oil to run. The oil return check valve should be replaced on schedule. The oil produces too much foam and the oil deteriorates or is overdue. 4. Insufficient exhaust volume and exhaust power. For insufficient exhaust gas and exhaust gas, first check whether the air filter is blocked or not. Clean or replace the air filter cartridge regularly according to the use environment and usage time. Secondly, check whether the relief valve is moving. If the unloading valve is stuck or the movement is not flexible, it will affect the intake air volume of the main engine. It is necessary to regularly maintain the unloading valve. Another reason is that the air consumption exceeds the rated displacement of the air compressor. W12.08-41 Electric Single Beam Crane End Beam Improvement Li Jiafei Liang Xiuxia Company is a professional manufacturer of electric single beam cranes for production, installation and maintenance. It is found that the design structure of the electric single beam crane end beam active device is unreasonable. Two kinds of electric single-girder crane end beams with lifting weight of 3~5t, 17~22.5m and lifting weight of 10t, 7.5~22.5m, the main problem is the four screws of the end beam active wheel ring gear Unable to find in time, when the bolt is found to be loose, the ring gear has worn out. If the bolt tightening the position must remove the wheel and the shaft, it takes time and effort. Find a suitable position on the diameter of the main ring of the main beam drive wheel (), add a straight process hole, make a good book and tighten the ring gear when the crane is made, it is easy to find during routine inspection and maintenance. problem. Move the wheel centerline down 3cm. Users can solve the problem without having to remove the wheel to solve the problem, which is convenient and practical.

Needle roller, also known as needle cylinder. A metal cylinder with steel needles planted on the surface. It is installed in the drafting zone for controlling and carding fibers. It is used on spun silk and wool spinning roving frame, carded wool spinning frame, spun spinning and shaft spinning frame. The main body of the needle roller is a copper cylinder with small holes drilled on the surface and steel needles are planted in the holes. Both ends of the cylinder are equipped with a flange, the surface of which is slightly higher than the needle tip to protect the needle tip from damage. The main parameters of the needle roller are: bottom diameter, outer diameter, needle width, needle height, needle density, needle angle and needle number. In order to adapt to the processing of different types of fibers, the small carding roller on the rotor spinning machine has the saw teeth replaced with needles, also called needle rollers.
