Three kinds of erroneous operations that damage farm machinery

First, with the silk cover air filter Some of the operators in order to enhance its small drag filter effect, the air filter is covered with a layer of silk cloth, think that this can make the air cleaner. I wonder if the silk will hinder the smooth air flow into the cylinder and make the air supply to the cylinder insufficient. The combustion will be incomplete, resulting in black smoke and power drop. 2. Tighten the cylinder head cap screws with adjustable wrenches. The tightening force of the cylinder head nuts of various types of engines must be balanced. Use special sleeves and torque wrenches to evenly tighten the diagonals from the center to the edges. Some hand-operated wrenches are used as substitutes, which are easy to overpower and destabilize the nuts; and the screw tightening torque is uneven, which can easily cause the plane deformation of the cylinder head. Third, when the diesel engine is overhauled, some operators will repeatedly scrub the parts and the interior of the crankshaft with cotton yarn and diesel oil. Although the oil is removed, the tile is burned for a short time. This is because a layer of cotton fiber is attached to the oil filter in the oil pan, which prevents the oil from entering the oil passage and causes burning of the tiles. Therefore, the cleaning part should use a brush.
A urinary tract infection (UTI) is an infection in any part of your urinary system - your kidneys, ureters, bladder and urethra. Most infections involve the lower urinary tract - the bladder and the urethra.
Women are at greater risk of developing a UTI than are men. Infection limited to your bladder can be painful and annoying. However, serious consequences can occur if a UTI spreads to your kidneys.
Doctors typically treat urinary tract infections with antibiotics. But you can take steps to reduce your chances of getting a UTI in the first place.
