Incorrect operation damages agricultural machine life
First, remove the vent pipe 95 diesel engine gear chamber cover is equipped with a plastic pipe leading to the intake pipe, this pipe is called ventilation pipe, its role is to use the vacuum formed by the diesel engine intake, so that the gas in the crankcase Inhaled combustion in the cylinder. It is also possible to balance the air pressure in the crankcase with the air pressure in the intake pipe so that the oil in the crankcase does not leak. After a period of use, the vent pipe will be damaged due to deterioration of the plastic. Some operators use wooden wedges to block the vent hole. This is not good for diesel engines. If a small amount of air is not filtered, directly entering the cylinder through the plastic tube hole left by the intake pipe will accelerate the wear of the parts. In addition, the exhaust gas in the crankcase does not drain out, causing the oil to rise and the lubricating performance to be impaired.

Second, with a silk cover air filter machine In order to enhance the small drag filter effect, in the air filter cover a layer of silk cloth, that the air cleaner this way, the power of the small drag has dropped, and take Black smoke. The reason is that silk is a hindrance to the smooth entry of air into the cylinders, making the cylinders under-inflated and burning incomplete. Therefore, this method is not desirable.
Third, the use of adjustable wrench tight cylinder head cap screws of various types of engine cylinder head nuts have a certain degree of tightening torque, and the tightening force of each nut should be balanced. Therefore, use special sleeves and torque wrenches when tightening the cylinder head nut. When some operators do not have a special tool, they use an adjustable wrench instead. This has many disadvantages: First, the adjustable wrench is easy to overpower, and it will screw the nut. Second, because the cylinder head screws have a large twist angle, the adjustable wrench cannot be calibrated. Torque will make the screw tightening torque is not uniform, it is easy to cause cylinder head plane deformation.
4. When the diesel engine was overhauled, the operator repeatedly scrubbed the parts and the interior of the crankshaft with cotton yarn and diesel oil. The oil was removed and it appeared to be very clean. It was thought that this could reduce the wear of the machine parts, but it burned for a short time. watt. This is because a layer of cotton wool is attached to the oil filter in the oil pan, which prevents the oil from entering the oil channel. These yarns are hung on the parts, so the cleaning parts should be brushed.
Fifth, increase the belt pulley The worker-peasant-12 type handwheel is equipped with a pulley on the flywheel, used to transmit the power with a certain speed mechanical value to the gearbox, through the shift to carry out the work load. After the pulleys have been changed to large and small, their mechanical values ​​have also changed, and the parts have also lost their balance of operation, so accidents can easily occur.
SanQiang medical companies specializing production Indicator.
Medical Indicator in the verification of the sterilization procedure,although the sterilization effect can be evaluated through the monitoring of certain parameters of the sterilization process,the degree of killing of the biological indicator is the most intuitive indicator for evaluating the effectiveness of a sterilization procedure.Commercially available standard biological indicators can be used,as can spores prepared with the most resistant micro-organisms isolated during daily production monitoring of contaminants.In the biological indicator verification test,the D value of the spore under the actual sterilization condition needs to be determined,and the spore purity and quantity are determined.When verifying,the microbial indicator of the biological indicator should be larger than the routine detection of microbial contamination,and the tolerance is strong to ensure that the sterilization procedure has greater safety.In the final sterilization method,biological indicators should be placed in different parts of the sterilizer.And avoid direct contact with the indicator to be sterilized items.The biological indicators are sterilized after being sterilized according to the set conditions,and cultured in a culture medium respectively to determine whether the spores in the biological indicator are completely killed.
Medical indicator in the sterilization biomonitoring of medical indicator,the standards
