What to do to prevent 50kw oil leakage of Perkins diesel generator set?

After the diesel generator set is used for a few years or longer, the gap between the parts increases, the accessories are worn, and there is often oil leakage. Here are a few ways to teach you how to prevent oil leakage in your unit! (Yanan Motor).

1. Adhesive glue leakage control method, oil tank, water tank, oil pipe, water pipe due to rupture or trachoma, porosity, etc. caused by small leakage, can be applied to the clean and damaged by adhesive repair glue.

2. Add pad leakage method, oil leakage at the leak-proof gasket of the oil pipe joint in the diesel generator set, you can add a layer of double-sided slippery plastic pad on both sides of the leak-proof gasket, and tighten it hard to prevent leakage.

3. Drain treatment method. When the oil pan, cylinder head, gear chamber cover, crankcase back cover and other paper pads of the diesel unit leak, if the paper pad is intact and the joint surface is clean, a layer of butter can be smeared on both sides of the paper pad and the bolts can be tightened to prevent leakage; If you change the paper pad, soak the new paper pad in oil for 10 minutes, then take it out and wipe it off, and then apply a layer of butter on the joint surface and then put it on. (Yanan Motor).

4. Paint liquid leakage control method. Leakage at the joints of diesel engine fuel tank, water tank, crankcase, etc., you can soak the paint sheet in alcohol, and then apply the paint liquid to the cleaned joints.

5. Anaerobic glue leakage treatment method. When there is leakage in the ventilation bolts and stud bolts on the diesel engine, anaerobic adhesive can be applied to the cleaned bolt threads or screw holes, which can quickly solidify to form a film and fill the gaps in the parts; This method is used for the thread of the high-pressure oil pipe joint of the diesel engine, and the leakage treatment effect is better.

6. Liquid sealant leakage treatment method. When there is an interface leakage and destructive leakage caused by solid gasket defects on the diesel engine, a liquid sealant is applied to the joint surface of the cleaned solid gasket, and a uniform, stable and continuously adhered peelable film gasket is formed after curing, which can prevent leakage.

7. Size recovery glue leakage control method. When the shaft and bushing, bearing and bearing seat, valve and valve acne, self-tightening oil seal, packing and other places of the diesel engine leak, the size recovery glue can be applied to the worn parts of the cleaned fittings, and after curing, a wear-resistant and high mechanical strength film layer is formed, and then the geometry and matching accuracy of the parts are restored by machining, which can solve the leakage.

Once the diesel generator set has an oil leak, it will not only cause a waste of fuel, but also mean that a part of the unit may fail. It can be seen that the hazard of oil leakage in the unit is very important, so it is very important to prevent the oil leakage of the diesel generator set.

1. The use of sealing adhesive can play the role of sealing, leak-proof, fastening and plugging the gaps, so as to prevent oil leakage.

2. In the process of disassembly, synchronous operation should be adopted, such as two people operating at the same time, and the bolts should be screwed evenly as much as possible.

3. Pull out the puller as much as possible in places where conditions permit, so as to fundamentally solve the synchronization problem.

1. There is water in the fuel, which is not easy to catch fire;

2. When air enters the generator oil supply system and the plunger of the high-pressure oil pump rises, the air can only be compressed to reduce the oil pressure and reduce the oil supply or not to supply oil. (For reference only: Fujian Yanan Motor A).

3. There is no oil in the fuel tank or the fuel valve is not opened;

4. The oil circuit of the fuel system is blocked, and the oil cannot be injected;

5. The temperature in the combustion chamber and cylinder is too low, the fuel is not easy to atomize, and the thick mixed gas formed by too much fuel is not easy to ignite and burn, so it is not easy to start.

6. The injection quality of the generator fuel injector is poor, so that the fuel atomization is not good, and it is not easy to form a combustible mixture.

7. The oil supply of the high-pressure oil pump is insufficient, and the oil supply pressure is too high or too low.

8. The engine injection time is too early or too late.

Perkins diesel motor unit is a kind of power generation equipment with diesel as the main fuel, with Perkins diesel engine (also known as Rolls-Royce) as the driving force to drive the generator (i.e., electric ball) to generate electricity, and convert kinetic energy into electrical energy and heat energy.

Perkins-Rolls-Royce diesel engines have a power range of 5 2500 hp (4 2100 kW) and are used to drive vehicles, agricultural machinery, generator sets, industrial equipment, construction machinery, etc. The new series of EFI diesel engines adopts an in-line 6-cylinder structure and applies the latest electronic fuel injection management system (ECM), so it has the characteristics of small size, light weight, stable performance, low fuel consumption and low emissions. Its emissions are currently the lowest emission models for industrial engines in China, reaching the level specified by the European Community and the United States Environmental Protection Agency for the third phase of emissions (EU-EPA Tier 3), and at the same time meeting all the requirements of the German Taluft and the second stage of the French CO2 limit for standby generator sets. Today, inheriting the name of Perkins, Perkins has developed into a leading supplier in the 4-2000kW (5-2600hp) diesel and gasoline engine market.

In the industrial, construction, agricultural, marine and power generation equipment markets, major international OEMs choose Perkins to power their equipment.

Perkins diesel generator set is composed of diesel engine and generator, if you want to buy a complete set of units, then you have to choose.

The OEM manufacturers of Perkins diesel generator set manufacturers are authorized by them to agree to the above brands to form a set of diesel generator sets, and at the same time obtain the quality assurance and after-sales service of the above brands.

In addition, it is necessary to pay attention to the power and configuration selection of the unit, the mechanical and electrical performance of the unit, the purpose of the unit, the capacity and variation range of the load, and the automation function.

When purchasing Perkins diesel generator sets, we should pay attention to the following matters:

1. When purchasing diesel generator sets, the comprehensive performance and economic indicators of diesel generator sets should be fully considered, the professionalism, geographical location and actual professionalism of the businessmen, and whether the merchants have after-sales service means, such as emergency repair vehicles, special machinery and tools, etc.

2. Then consider whether the power of the selected unit matches the power of the electric load. Generally, it is better to select the power of the unit based on the rated power of the unit and the power of the electrical equipment.

If there are large and medium-sized motors, it is also necessary to consider 2-5 times the starting current. If the unit is mainly used to charge UPS, it is necessary to make a professional consultation according to the actual situation of UPS, and then decide the rated power of the generator.

The generator market is mixed, and informal family workshops are rampant, so the purchase of generator sets should go to professional OEM manufacturers for consultation, including product configuration and after-sales service projects, etc., and refuse to refurbish or second-hand machines.

The main reasons for the oil leakage of the 50kw Perkins diesel power generation and closed land delay power unit are as follows:

1. The quality of the purchased or self-made paper mat does not meet the requirements, such as insufficient thickness, improper storage, wrinkled deformation, or lack of attention to cleaning during assembly, and dust impurities, which are the causes of oil leakage.

2. The oil pressure is too high, which also causes oil leakage on the static joint surface.

3. The quality of the joint surface of the sedan car is mainly determined by the accuracy of the processing equipment itself and the storage and pure transportation conditions. If the equipment has high precision, the flatness and roughness of the static joint surface can meet the requirements of the drawing design, and attention should be paid to preventing bumps during storage and transportation, etc., it is not difficult to achieve complete sealing of the static joint surface. However, due to the low level of equipment and technology of some manufacturers, the storage and transportation conditions and management level cannot fully guarantee that there are no bumps and scratches.

4. Poor operation technology during maintenance. At present, diesel generator sets are generally self-repaired, due to the repair technical level can not keep up, self-repair often occurs this or that problem, especially when disassembling and assembling the machine, do not pay attention to the method, lack of special tools, so that the parts are deformed, and even damaged. Oil leakage is caused by deformation of parts.

There are also some things to pay attention to when operating diesel generator sets in hot weather.

1. When the diesel generator set is in use, it should be placed in a dry place outdoors or in a well-ventilated place in the machine room, so as to allow air circulation. It is forbidden to place flammable and explosive materials near the diesel unit to avoid potential safety hazards.

2. The circulating cooling water in the water tank should be kept in sufficient condition, so that the generator set can maximize the heat dissipation during operation.

3. Be careful not to run the diesel unit for a long time, and the unit should be suspended every 5 hours to avoid wear and tear caused by the operation of the unit in a high-temperature environment.
