1. Mowing boat engine cylinder head due to long-term work in high temperature, high pressure, heat load and alternating load and warping deformation, cylinder pad from the water outlet is broken, resulting in combustion chamber pressure drop, engine power shortage and radiator water outlet out of the water.
2. Changed the cylinder gasket twice in succession, and it was washed out after using it for a month respectively. After open a look, found that the cylinder block, cylinder head deformation. The flatness error of the cylinder block is 50μm, which still meets the technical requirements, but the flatness error of the cylinder head is 0.20mm, so this deformation is mainly the cause of the cylinder pad washed out.
The repair technique is to see the mowing boat engine cover without combustion chamber concave, do not have to consider the change of combustion volume (the change value of combustion chamber volume should not be greater than 4% of the original volume), the surface milling method is used to process the cylinder head plane, in the cylinder head and cylinder body joint surface of the water channel to install a copper pad (the thickness of the copper pad is 1.2 times the thickness of the water channel concave platform), Replace the rubber seal ring on the cylinder gasket, and then install the cylinder gasket, and tighten the cylinder head bolt using the first cold and then hot tightening method. Using this technique to repair the engine, there will be no punching cylinder pad failure. It's simple and safe.
Mowing boats have become indispensable mechanical equipment in industries such as infrastructure, because the product yield function is better than traditional mowing technology equipment. In the market has been a lot of customer praise, occupy a favorable sales position. The operation and maintenance of the product is cheap and cut the characteristics of good economic benefits, must be all the machinery to stop after a large stone or mud layer, the ship experience a violent vibration phenomenon, the new mowing ship and the larger material can also be processing, stand out in the mowing ship market, mowing ship has become the world's weeding equipment, and according to an important position in the field of building materials industry.
A wide range of waters, including rivers or lakes, apply to such lawnmowing vessels. The typical engineering type for a very large mowing boat is different from that for a mowing boat. In most cases, such ships are used for relatively small projects throughout the world, such as the nearshore section of pipelines, seaborn sewers, port construction and various special projects in the offshore industry. Some of the long-term projects foreseen in the future are the widening of the Panama Canal and other canals and the laying of long-spaced pipelines.
