Introduction In order to ensure the normal operation of the 1100 kW generator, what should be paid attention to when inspecting the piston rings? 1. Opening clearance inspection method: Diesel generator piston ring opening clearance refers to the piston ring assembly.

In order to ensure the normal operation of the 1100 kW generator, what should be paid attention to w

1. Opening clearance inspection method: Diesel generator piston ring opening clearance refers to the space between the two ends of the ring opening after the piston ring is installed in the cylinder, it is therefore also called end game. to prevent the piston ring from getting stuck in the cylinder by thermal expansion. When checking the piston ring opening gap, install the selected piston ring flat into the cylinder, use the piston head to push the piston ring to the unworn part of the cylinder, and then use a feeler gauge to measure aperture gap. If the deviation is greater than the specified value, another piston ring must be selected; if it is less than the specified value, a hand grinder or a fine flat file can be used to file the first end of the segment. When filing, you should pay attention to the smoothness of themouth of the ring. After filing, remove the burrs on the outer ring mouth to prevent the sharp edges of the ring mouth from tiring the cylinder wall.

2. Side gap inspection method: The side gap of the diesel generator piston ring refers to the space between the ring and the plane side of the ring groove. When measuring, place the piston rings in their respective grooves. They must be able to rotate flexibly without any stagnation. Use a feeler gauge to measure the gap on one side. When detecting the side clearance of the scale ring, it should be installed in the cylinder with the piston and measured, and its value should conform to the regulations. If the side gap is too large, it will affect the sealing effect of the air ring, and it needs to be refitted if the side gap is too small or the ring is wider than the groove of the ring, except for the trapezoidal ring, it must be readjusted and ground. Rings of other shapes can be placed over the joint on No. 0 gauze on a platform or flat glass. When grinding, keep the ring close to the emery cloth and move it evenly. You can also use flat glass coated with abrasive sand and dripping oil for grinding.

3. Clearance inspection method: Diesel generator piston ring clearance refers to the space between the back of the piston ring and the bottom surface of the ring groove after the piston and piston ring are installed in the cylinder. For ease of measurement, the measurement value is generally based on the distance the piston ring falls into the ring groove under the shore. It is generally believed that this measurement value only needs to be greater than 0~0.35mm. If it is too small, the ring will get stuck in the cylinder. If the gameis too low, it can be solved by digging deeper piston ring grooves.

4. How to check the elasticity of the piston ring: To check the elasticity of the piston ring, place the piston on the elasticity tester, pull the operating handle and secure the handle when the piston ring is compressed to the specified opening space, then adjust the scale to balance the two ends. The corresponding scale of the scale is the elasticity value of the ring. Generally, this measurement is rarely performed. The repairman only needs to feel the elasticity with his hands, that is, whether the outer circle feels "hard" when pinched with his hands.

5. How to Check for Light Leaks: Light leaks refer to the degree to which light can penetrate between the ring and the cylinder wall when the piston ring is installed in the cylinder. When inspecting, place the segment of piston horizontally in the cylinder, cover the inner circle of the segment with a circular plate, place a light source under the cylinder, then check the light leakage space. It is necessary that there is light leakage space. within 30° at both ends of the piston ring opening space. If there is a light leak, there should be no more than two light leaks from the same piston ring, the total arc should not exceed 45°, and the light leak space should be less than 0.03mm. When the light leakage gap is less than 0.015mm, the arc can be relaxed appropriately, but it should not exceed 120°.

1) The piston ring is installed flat in the liner of cylinder, and there must be a certain amount of space at the interface. 2) Piston rings It must be installed on the uddertone and there should be some lateral play in the height direction in the annular groove. 3) The chrome ring should be installed on the first line and the opening should not face the direction of the vortex on the top of the piston. 4) The openings of each piston ring must be offset by 120°C from each other and must not face the piston pin hole. 5) For piston rings with a tapered section, the tapered surface should face upward when installed. 6) When installing the twist ring, the chamfer or groove should be upwards. 7) When installing the combination ring, the axial socket ring should be installed first, followed by the flat ring and the wave ring. Install two flat rings on top of the wavy ring and one flat ring on the bottom. The openings must be offset from each other.
