Machining Stainless steel is the use of CNC machining out, including drilling, boring, cutting, turning, screw, etc.. Machining stainless steel commonly used materials: sus303304316.stainless steel has a very high hardness after machining, easy deformation, so in the process of rough machining to eliminate stress, and then finished. Surface treatment is generally passivation, we have specialized laboratories to test products, and ensure that each size to meet the requirements of the drawings, including the machining stainless steel application in various industries: automobile, ship, crane, medical equipment, industrial automation equipment.

How to save the diesel engine oil consumption?
Diesel generator sets are the main backup power source for manufacturing companies. The main fuel used is diesel fuel. At present, with the continuous rise in oil prices, engine oil is also rising. To reduce the use cost, it is important to use the generator set as much as possible. Reduce fuel consumption, save fuel. Then as a user of the generator set. How to use the diesel generator set?
First of all, we need to understand the reasons for excessive oil consumption before we can take appropriate measures.
1. The normal wear caused by long-term use of the engine, or abnormal wear due to improper maintenance, will cause the cylinder liner of the diesel engine to form a longitudinal pull, and the bore and piston side clearance exceeds the specified value, so that the support force of the piston ring is reduced accordingly. Small, there is no net phenomenon. Or because the inner ring in the oil ring distorted the spring to break in the opening position of the oil ring, resulting in the oil is not clean and participate in the combustion, resulting in serious consumption of oil symptoms, manifested as diesel engine start difficulties, the exhaust pipe has obvious blue smoke Severe respirator injection. In addition, the piston should be on the upward side. When the assembly is reversed due to the direction of the direction of the combustion chamber to form an inverted state, although it will not affect the start of the diesel engine, but the loss of oil will be quite serious, the daily fuel consumption is about 0.5 kg.
Second, when it is found that the engine oil consumption is too high, it should first check the body and gear room cover, wheel side of the big plate, back cover, cover and other joints are leaking. Care should be taken to observe the integrity of the seals at each joint, and replace the damaged seals. If the seal is complete, check the looseness of the connecting screws at each location. Use a wrench to loosen the bolt to the specified torque. If the above parts are normal and the oil leakage is at the rack position, check the oil casing. The main inspection location is on the front side of the oil tank side on the same side as the traveling wheel. Loose screws on the base are used to pull the wheel in the V-belt. A long-term collision with the angle iron on the frame of the protection oil shell is caused, and the oil shell is worn out to form a gap and generate oil leakage.
Third, serious wear of the valve guide tube can also affect the oil consumption of the diesel generator set.
　 How to better make the machine more fuel efficient?
1) Maintaining a good oil supply angle: The oil supply angle shift will cause the oil supply time to be too late and the fuel consumption to increase greatly.
2) Ensure that the machine does not leak oil: The way to deal with it is to apply the valve coating on the glass plate and smooth it on the glass plate. With the addition of a diesel recovery device, a plastic pipe can be used to connect the oil return pipe on the nozzle to the air-core screw so that the return oil flows into the fuel tank.

3) Improve the cooling water temperature of the diesel engine: The higher water temperature can make the diesel more complete combustion, the oil viscosity will be small, the movement resistance can be reduced, and the fuel saving effect can be achieved.
4) Appropriately increase the number of diesel engine pulleys to increase the speed of the pump when the diesel engine is running at a reduced speed, so that the flow rate and lift can be increased to achieve the purpose of energy saving.
5) Purge the oil before use: More than half of the failures of the diesel generator set come from the oil supply system. The method of treatment is that the bought-back diesel is left to settle for 2-4 days before use, and 98% of impurities can be precipitated. If it is purchased now, two layers of silk cloth or toilet paper can be put in the fuel tank filter screen.
6) Adjust the fuel injection pressure of the injector.
It is believed that as long as the above six energy-saving schemes are completed, the fuel consumption of the diesel generator set will be greatly reduced, and the operating efficiency of the generator set can also be fully utilized to reduce the user's cost.
