2. When installing, if the shaft surface roughness is low or there are rust, rust, burr and other defects, use a fine emery cloth or oil stone polished smooth; apply oil or grease to the oil seal lip or shaft diameter corresponding position. The outer seal of the oil seal is coated with a sealant, and the keyway portion of the shaft is wrapped with stiff paper to avoid scratching the lip of the seal, and the oil seal is rotated inward with a special tool. The hard seal cannot be used to prevent deformation of the seal. Or break the spring and fail; if there is a lip flange, spring off and oil seal skew must be removed and re-installed. It should be noted that when the shaft diameter is not worn and the spring force of the oil seal spring is sufficient, do not tighten the inner spring without authorization.
3. Oil seals applied to agricultural machinery generally require inspect, maintenance and maintenance when the working conditions are generally poor, the temperature difference between the environment is large, the dust is excessive, and the vibration of the implement frequently causes changes in the mechanical conditions of the components.
4, if the shaft diameter and bearing wear serious; oil seal rubber aging or spring failure, etc., should be repaired and replaced the corresponding parts.
5, the abnormal heating components or assemblies should be promptly troubleshooting; to avoid mechanical overspeed, overload operation, to prevent the oil seal lip temperature, rubber aging, early wear lips and so on.
6, always check the oil level, if there is too much oil impurities, there are alloy powder, metal scrap iron to completely replace the new oil. The brand and quality of the replaced oil must meet the requirements of the season.
7. Oil seals that are not used temporarily should be properly kept from oil, dust or sun exposure.
8, when the shaft diameter wear into a "V"-shaped groove, so that the new oil seal lip and shaft contact pressure can not play a sealing role, you can use AR-5 a two-component adhesive Glue, both simple and reliable and wear . Oil seal displacement can also be used to make up for.
Construction machinery is engineering construction and urban construction necessary machinery and equipment
product:Asphalt Mixing Plant,Asphalt plant,Asphalt concrete plant,Concrete mixing plant,Concrete Mixer,Wet mix plant, wet mixing plant.
Asphalt mixing plant and Asphalt plant are all used for mixing asphalt mixture,which is integrated with excellence of similar products within and outside our nation, such as accurate weighing, equal mixing, well dust removing, etc. Its working theory is as follows: firstly it heats stones and asphalt to a definite temperature, then mixes the stones, asphalt, powders, additives together at a prescribed proportion, and finally produces the black mixture used for asphalt road. It is widely applied into the construction of road, port deck, city road,squares,airport etc.
Asphalt concrete plant,Concrete mixing plant,Concrete mixer,all these plant is a kind of construction material production equipment, which is made up of mixer, material weighing system, material conveying and supply system, material storage system, control system and other affiliated instruments. Its working principle is mixing cement with different sizes of aggregates, lime powder and coal ash together, finally producing the concrete, which can be used as wall material for construction of water conservancy project, electric power project and bridge projects etc.
Wet Mix Plant and wet mixing plant is featured with advanced structure, aggregates are weighed by belted electronic balance, filler will be weighed by electronic screw balance, water will be weighed by frequency conversion comparison; all the motors equipped are frequency conversion timing, and the plant is also module design, automatic control, accurate weighing and better mobility.it`s also applied into construction for road basic layer of different kinds of grade.
