Injection of fuel on the top of the compressor piston results in increased lubricant consumption

Turning into the compression stroke condition, the crankshaft drives the piston to rise, and the ring is pressed by the gas to the lower side of the groove. During the process of switching the cylinder from the suction stroke to the compression stroke and from the compression stroke to the suction stroke, that is, when the cylinder is switched, the piston and the piston ring are subjected to the pressure of the gas, and the ring is suspended in the ring groove. status. Thus, the movement of the piston and the piston ring is stopped and the lubricating oil enters the inside of the ring. Due to the up and down movement of the ring, the oil moves from the lower side to the upper side and is finally sent above the cylinder. This is the pumping action of the piston ring. With the wear of the ring groove, this pumping oil will become stronger and stronger. The ring groove is further enlarged, and the lubricating oil is sucked into the air chamber to form an oil injection on the top of the compressor piston, thereby causing an increase in the consumption of the lubricating oil; and if a certain part of the body is not tightly sealed, oil leakage may occur.

The high pressure piston oil groove return hole is too small. During the process of tackling the offensive, it was found that the "injection" phenomenon of the high pressure piston was more serious than that of the low pressure piston. It is found that the diameter of the oil return hole of the low pressure piston oil groove is 4.5mm, and the diameter of the oil return hole of the high pressure piston oil groove is only 3.5mm. The lubricating oil scraped by the oil groove forms a bottleneck at the oil return hole of the high pressure piston oil groove, and cannot be reflowed in time. , intensified the role of pump oil, causing fuel injection. Piston ring movement (a) suction stroke; (b) compression stroke; (c) condition change stroke locomotive electric drive 2003 direction of the reverse station signal range in front of the station to control. The reverse inbound signal of the monitoring device can be set to the kilometer of the station's inbound or reversed inbound. When the construction allowable speed input value is higher than 40km/h, the monitoring limit speed will default to 40km/h. In the piston and piston ring matching, the clearance between the ring and the ring groove is modified from 0.25~0.52mm to 0.02~0.05mm. After the ring is replaced, the contact state with the cylinder is poor. In the later stage of the running-in test, the contact surface between the piston ring and the cylinder should be checked. The diameter of the oil return hole of the high pressure piston oil tank is increased from 3.5 mm to 4.0 mm. The oil return capacity is improved by 31% by improvement. Through the running-in test, the contact between the piston ring and the cylinder wall is strictly checked, and the contact surface is required to reach 80% or more to prevent the piston ring and the cylinder from sticking together, resulting in air leakage and oil leakage.

Tapered idler is also called conical idler, Cone Idler, taper Idler Roller. Tapered idler has the advantages of wear resistance, long service life. Light weight, small rotating inertia, reasonable structure reliable sealing and excellent corrosion resistance.

Features:
