Why is the turbocharger the component that is most prone to failure in an engine

 Because the rated working speed of the supercharger is more than 130,000 revolutions per minute, and it is at the outlet of the exhaust manifold, the temperature is extremely high (above 800 °C), and the inlet and exhaust pressure is also large, that is, high temperature, high pressure and high speed, so the requirements for lubrication, cooling and sealing of the supercharger are relatively high. In order to ensure the service life of the supercharger, the design should ensure the lubrication and cooling of the supercharger floating bearing, and at the same time, it is required to do the following in use:


(1) After the engine starts, it should idle for 3-5 minutes, and do not immediately increase the load to ensure the good lubrication of the supercharger. The main reason is that the supercharger is located at the top of the engine, if the supercharger starts to run at high speed immediately after the engine starts, it will cause the oil pressure to fail to rise in time to supply oil to the supercharger, resulting in the supercharger lack of oil damage, and even burn out the entire supercharger.

(2) The idle time should not be too long, generally not more than 10 minutes, and too long the idle time is easy to cause oil leakage at the end of the compressor.

(3) Do not turn off the engine immediately before stopping, and should idle for 3-5 minutes to reduce the speed of the supercharger and the temperature of the exhaust system to prevent the occurrence of heat recovery, oil coking, bearing burning and other failures. Frequent incorrect use can cause damage to the booster.

(4) For engines that have not been used for a long time (generally more than 7 days), or engines with new superchargers, oil should be filled into the oil inlet of the supercharger before use, otherwise the life will be reduced or the supercharger will be damaged due to poor lubrication.

(5) Regularly check whether there is loose air leakage/oil leakage in each connection, and whether the oil return pipe is unobstructed, and if so, it should be eliminated in time.

(6) Ensure that the air filter is clean and replaced regularly as required.

(7) Change the oil/oil filter regularly.

(8) Regularly check the radial axial clearance of the supercharger shaft, the axial clearance should not be greater than 0.15 mm, and the radial clearance is: the gap between the impeller and the pressure shell is not less than 0.10 mm, otherwise it should be repaired by professionals to avoid expanding losses.

How to extend the life of drill pipe

  1. When using a new drill pipe, the drilling rig manufacturer should make sure that the wire fasteners on the front cut-off (protecting the shaft head) of the drill bit are also close to the new one. A ring-buckled rotating head can easily damage the wire fasteners of the new drill pipe, resulting in leaks, snaps, and loosening, and so on. 2. In the use of drill pipe for a drilling, should be first “grinding new buckle”, which consists of, first smeared with silk buckle oil, and then use the drill rig full torque, and then open the buckle, and then smeared with silk buckle oil and then open, and so on for three times, you can avoid the new wear and buckle. 3. As far as possible to maintain the drill pipe under the ground and on the ground in a straight line, so as to avoid part of the side of the wire buckle force and cause unwanted wear and tear, or even jump buckle, pay attention to the rig anchored to avoid the construction of the force to move is very important. 4. The buckle...

What are the Basic Maintenance Methods for Water Well Drilling Rigs

  Cleaning: After every day's operation, clean the mud, oil, and other debris on the rig in time to keep the rig clean. Checking lubrication: regularly check  the lubrication points to ensure that the lubricant is sufficient and the grease is clean. Fasteners check: you can check whether the bolts and nuts of each part are loose and tighten them in time. Hydraulic system checks: you can check whether the hydraulic oil level is normal, whether there is no leakage phenomenon, and whether the hydraulic oil is clean. Lubrication system maintenance: regular replacement of lubricating oil, grease, cleaning oil filter, and oil tank. Hydraulic system maintenance: regular replacement of hydraulic oil, cleaning hydraulic filter. Cooling system maintenance: clean the radiator, and check the coolant level. Transmission system maintenance: check the tightness of the transmission belt, and replace the worn transmission belt. Electrical system maintenance: check whether the line is firm...

Use and maintenance of drill bits

Use and maintenance of drill bits: 1. Choose a suitable drill bit:  Before using a drill bit, it is necessary to select the appropriate type and specification of drill bit based on drilling conditions and needs. 2. Installing the drill bit:  When installing the drill bit, it is necessary to ensure that the connection between the drill bit and the drill pipe is firm, and to correctly install the cutting teeth of the drill bit. 3. Maintain appropriate drilling speed and pressure during the drilling process:  Excessive drilling speed and pressure can lead to premature wear and damage of the drill bit, while too small can affect drilling efficiency. 4. Regular inspection and maintenance:  Regularly check the wear of the drill bit and replace severely worn components in a timely manner. At the same time, it is necessary to regularly clean and lubricate the drill bit to extend its service life. 5. Storage and preservation:  When storing and preserving drill bits, it i...
