What kind of "Small holes" cannot be blocked on construction machinery ?
The following "small holes" on construction machinery cannot be blocked at all: (1) Water pump overflow hole and water hole. An overflow hole is formed at the shaft of the water pump. One is to observe the leakage of the water pump, and the other is that the leakage of the water pump can release the hole into the sky. If it is blocked, the leaking water can leave the pump hole and affect the lubrication, leading to early damage to the bearing and the water shaft. Or water seal. (2) The oil drain hole of the pump pump output oil pump body is used to make the pump body in the pump body pump oil directly. The blockage will cause some diesel pumps to fail to pump out the oil pump body but the pump oil pump of the oil pump body. The bottom shell skid, resulting in deterioration of gloss and damage to the parts due to poor lubrication. (3) The blockage will cause the diesel engine to start. (4) Diesel engine fuel injector oil hole. Once blocked, the drained oil cannot return to the fuel tank, the pressure in the oil return channel is high, the fuel injector oil becomes higher, and the fuel injection time changes, which can easily lead to oil jam. (5) Fuel injection pump respirator. After being blocked, it is easy to deteriorate and cause poor lubrication. (6) Each hole used for the diesel tank cover prevents normal fuel supply when the oil level drops. (7) The crankcase shaft and the oil port cover hole bend away from the trouble of entering the axle box from the oxygen channel. If it is blocked, it will cause ink leakage and oxidation. (8) Diesel engine oil hole, like rocking door rocker arm, rocker arm, and air push rod. If blocked, it will accelerate the maturity of the parts; blockage of the oil hole of the memory timing gear will lead to poor wear and aging, pale appearance, and strikes. Emitting a strange mouth; the centrifugal cosmetic fine filter is directed to two non-deteriorating objects on the body, such as stopping the rotation of the ingredients or slowing the speed, causing the color filter to lose its function, prematurely deteriorating the oil, and accelerating the mechanism. (9) There are air particles in the exhaust hole of the air filter. For example, the dirt will enter the first-level filter along with it, or even enter the air filter, accelerating the parts and causing dust power. (10) Many oil return holes in the inner groove of the oil ring of the diesel engine piston ring can promote the oil filter scraped from the wall to flow back to the box shaft. Blocking will cause a large amount of oil to enter the combustion endogenous, carbon deposits, and cause malfunctions. (11) The oil cooler, full water and drain holes are used to drain the cooling water everywhere. Blocking will cause the cooling water to fail. In winter, the cooler is easy to crack, water freezing and hobbies (common) are frozen cracked corn cooling器), resulting in losses. (12) Diesel engine auxiliary water drain cover hole. After clogging, there will be problems with the cover hole. After being blocked, the pressure of the secondary water source cannot be established, causing the cooling of the secondary water internal difference to be unable to flow into the main again, causing the cooling liquid level to be too low and affecting the heat dissipation effect. (13) Reservoir and liquid plug hole. Exit to prevent accidents from accidents caused by excessive gas accumulation. (14) The small holes in the hydraulic oil tank, rabbit, torque converter, hydraulic pump transmission box, etc., ensure that the altitude of the tank is connected, balance the internal pressure, and leave the outside air to prevent rapid temperature rise and premature deterioration of the fluid in the tank. (15) The hole on the main environmental protection device shell prevents excessive oil and air in the weather hood, and prevents premature damage to parts exposed to sunlight. (16) The master cylinder pump cover avoids the hole liquid, the master cylinder oil return hole and the auxiliary hole, which can ensure the replenishment and circulation of the brake, so that the brake is restored completely, and the hole invades the balance in the passage. Use finer dredging to ensure clean and unobstructed. Once blocked, it will cause unobstructed "biting", oil leakage of the master pump and other failures. (17) The small holes for the main clutch and steering to catch the eyeballs are used to quickly remove from various places. If blockage occurs, excessive oil will enter the surface of the friction plate, thereby attracting the clutch to hit, and the power sliding transmission is unstable.
