introduction： How to remove the clutch fault 1、If the above adjustment is normal，The separation is still incomplete，We need to remove the clutch，Check whether the driven disk is inverted、Whether the axial movement is difficult、There is no warping of the master-slave disk、Check whether the release lever screw is loose、Whether the floating pin falls off。 2、For the newly riveted friction piece of the clutch，Check whether the driven disk and friction plate are too thick；If too thick，Gaskets can be added between the clutch cover and the flywheel。 3、For hydraulic transmission of the clutch，In addition to the above checks，Should also

introduction：Hydraulic support is a supporting equipment in coal mining machinery，After overhaul, it can be used underground for five years，However, the service life of various hydraulic valves in the hydraulic support is very low，long3month，As short as a few weeks，The foreign solution is to increase the filtration accuracy of the system and improve the quality of the emulsion，But with little success。Take a hydraulic valve in the UK as an example，Although the machining accuracy and the filtration accuracy of the entire hydraulic system are relatively high，But due to low service life，Has faced elimination in our country。 1The main factors affecting the sealing performance of hydraulic valve The main factor of seal element damage is impurities in the working fluid。These impurities are in the sealing element

introduction：Reverse osmosis pure water machine is a household drinking water equipment that has not been on the market for a long time，But its emergence has been well received by a growing number of consumers,Especially popular with water dispenser users,Because he eliminates the cost of buying bottled water and the hassle of transporting bottled water。The biggest difference between a pure water machine and a drinking machine is that，A pure water machine is a device for making pure water，The water dispenser is a device that heats or cools purified water and facilitates people to use it；At present, the three-temperature landing pure water machine on the market has actually fully covered the function of the drinking machine。 one．principle So what is the way of pure water machine

introduction： Impact strength Metallic material﹑Resistance of mechanical parts and structures to impact damage。A load that acts on a part at a high speed over a short period of time﹐Weighing impact load。The stress caused by the impact load is called the impact stress。Because the impact time is very short﹐In addition to the object contact deformation and other factors﹐It is difficult to calculate the impact strength accurately。 Conventional impact calculation Impact load The impact stress generated in the part is divided by the shape of the part﹑The volume is related to local elastic-plastic deformation﹐It also has to do with the objects connected to it。For example, the object connected with the part is an absolutely rigid body﹐The impact can all be borne by the part
