How to calculate and analyze return on investment?

First, you need to determine the local energy structure and understand the cost of key elements such as electricity, fuel, and monthly energy costs. Our sales experts will provide a detailed return on investment analysis based on this information.

How to choose your new power generation equipment?

Many customers need to consider the technical and economic feasibility of diesel power generation solutions. Usually, the diesel generator set is combined with the external large power grid, and the energy supply complements each other, which can improve the reliability and flexibility of the entire system.

In order to find a cost-effective, technically reliable, and more environmentally friendly power generation solution, we recommend that you consider the following important factors:

1. The most important is the installation cost. Diesel generator set solutions offer very competitive installation costs compared to other power generation systems, with a limited footprint for a single kilowatt project.

2. Power generation efficiency. The power generation efficiency of diesel generator sets directly affects the economy of the project. PowerLink diesel generator sets are efficient and offer a high value.

3. Manufacturing and commissioning time. PowerLink diesel generator sets usually take 3 to 6 months from production time plus construction and commissioning time. Your cash-on-delivery time will be shorter if you have it in stock.

4. Modular installation solutions. Considering that the equipment is ultimately delivered safely to the installation site, the modular structure makes project installation easier and commissioning simpler and faster.

5. Operating expenses related to equipment. The following aspects are mainly considered: maintenance intervals, spare parts costs, downtime during maintenance, and the entire working cycle of the equipment before overhaul. Based on our long experience, we offer multi-year service contracts for PowerLink generator sets. This will help reduce the need for spare parts and can predict service times in advance to reduce operating costs throughout the engine’s working life.

6. Load analysis of the project helps you select the most suitable equipment. PowerLink’s wide range of diesel engines (5KVA to 3250KVA) is sure to help you find the right solution.

7. The surrounding environmental conditions will affect the use of the device, thus affecting its actual power output capability. In other words, in some cases, your power output may be much lower than the rated power. If you plan to operate equipment at high temperatures/altitudes significantly above sea level, you need to take this into account.

Where can I buy PowerLink products?

We have distributors in more than 100 countries around the world, you can contact your local distributors to purchase products. Or contact our factory directly and one of our sales experts will work with you one on one.

Can the generator set be used in bad weather conditions?

In terms of design, the PowerLink generator set can operate in harsh environments and extreme weather conditions (recommended ambient temperature: -25℃ ~ 50℃, altitude ≤1000m), but generally we do not recommend harsh conditions to use. In order to extend the service life of the generator and prevent things like short circuits and rust, they should be protected from the components as much as possible.

What is a transfer switch?

A transfer switch is a panel that is connected to the site’s power distribution system to allow the use of a generator. It prevents the generator from feeding back into the main power supply, which can cause serious injury to workers trying to restore utility power lines.

Do you provide transfer switches and distribution equipment to distribute electricity?

PowerLink currently provides automatic transfer switches and transmission and distribution systems, which can be negotiated according to the actual situation of the project.

How to reduce noise of generator set?

The following three methods are commonly used for noise reduction.

1. Exhaust noise reduction, exhaust noise is the most important noise source of the unit, usually use a special silencer to reduce noise.

2. Reduce axial fan noise.

3. Sound insulation, sound absorption processing, and vibration isolation of the unit in the equipment room.

What's with the reverse power? What are the two serious consequences?

The case of a self-provided generator sending power to the municipal network is called a reverse power supply. There are two kinds of serious consequences.

a) If the municipal power grid is not cut off, the municipal power supply and the self-provided generator power supply will produce non-synchronous operation, which will destroy the unit. If the self-provided generator capacity is large, it will also make the municipal power grid shock.

b) City network power outage is being tested, its own generator back power. It will electrocute some of the inspection staff.

What are the conditions for the parallel use of two generator sets, and what devices are used to complete the parallel work?

The condition of parallel use is that the voltage, frequency and phase of the two machines are the same at the moment, and the generator set is commonly known as “three simultaneous”, and the special parallel device is used to complete the parallel work. It is generally recommended to use a fully automatic cabinet and try not to manually parallel, because the success or failure of manual parallel depends on human experience, and the success probability is low.

Cause high water temperature alarm shutdown and can not be used, what are the reasons?

Water tank leakage or insufficient water; Water temperature sensor is damaged; Water tank waterway dirt is too thick or heat sink oil is too much;

Fan belt wear is too large, insufficient pressure; Pump wear, pump water is insufficient; Thermostat opening Angle is not enough, there is a stuck phenomenon; The cylinder gasket is damaged, and the water channel is connected with the cylinder; Cylinder liner wears too much, local water seepage; The ventilation of the equipment room does not meet the requirements. Engine overload operation; Excessive fuel supply (including engine weakness).

How does the generator set work with the main power supply?

The stable mains power is supplied to the carrier through the cable. When the main power supply is interrupted due to a power outage, the signal is sent from the transfer switch to the generator set, which then starts and sends the generated power to the carrier. When the main power supply is restored, the switch will cut off the power supply to the generator set and restore the main power supply.

How long is the product lead time?

Standard products from the customer order to the product factory, depending on the power and series, generally in 2-6 months

How is the equipment shipped?

PowerLink works with a variety of contract carriers to deliver goods to the sites specified in the contract. We offer our customers two options, truck delivery or full-service delivery, including unloading equipment, according to the actual situation of the project to adopt the corresponding transportation plan.

What do I need to know when installing a generator set?

The following aspects usually need to be paid attention to when installing a generator set:

1. The installation site should be well-ventilated, the generator end should have enough air intake, and the engine end should have a good air outlet.

2. The area around the installation site should be kept clean and avoid placing items that can produce acidic, alkaline, and other corrosive gases and vapors nearby. If conditions permit, fire extinguishing devices should be equipped.

3. If used indoors, the smoke exhaust pipe must be passed to the outside, the pipe diameter must be greater than or equal to the diameter of the smoke exhaust pipe of the silencer, and the elbow of the connected pipe should not exceed 3 to ensure the smooth exhaust of smoke. In addition, the pipe should be tilted down 5-10 degrees to avoid rain injection, if the exhaust pipe is installed vertically, you must install a rain cover.

4. When the foundation is made of concrete, the levelness must be measured with a level during installation so that the unit is fixed on the level foundation. There should be special shock-proof pads or foot bolts between the unit and the foundation.

5. The unit shell must have reliable protective grounding, for generators that need to have direct grounding of the neutral point, it must be grounded by professionals, and equipped with lightning protection devices, it is strictly prohibited to use the grounding device of the mains for direct grounding of the neutral point.

6. The two-way switch between the generator and the mains must be very reliable to prevent reverse power transmission. The connection reliability of the bidirectional switch must be verified and approved by the local power supply department.

7. The wiring of the starting battery must be strong.

How to do equipment debugging?

Our factory has professional commissioning engineers who can provide equipment commissioning services worldwide. You can choose between online remote technical support or local on-site commissioning.

Precautions before commissioning the equipment?

Before each equipment and project commissioning, it is necessary to do spot inspection work in advance. You can find the after-sales department to get the inspection list, do the relevant work according to the requirements, and provide videos and photos to the after-sales department. Get the after-sales inspection list before commissioning, and put the project on the list.

How to protect alternator?

The alternator of the generator set can be protected in three different ways:

(TMP)Thermomagnetic protection

TMP protects the alternator from overload and short circuits.

If overloaded, the TMP will shut down after a specified period of time. This amount of time depends on the type of overload: the higher the overload, the shorter the time it takes for the TMP to shut down. In the event of a short circuit, TMP always shuts down immediately.

Leakage protection

When a leakage fault of more than 30mA, 100mA or 300mA occurs between the phase and the earth, the ELP automatically interrupts the circuit, depending on the type of leakage switch used.

In the case of indirect contact, ELP protects the person from electric shock. In addition, ELP can also be used as short-circuit protection. In most cases, ground pins are required!

Insulation protection

Insulation protection relays are used to measure and protect the insulation (in effect resistance) between a direct, ungrounded AC power supply and a freely selected ground area (i.e. the frame or mass of the generator set). In this way, the user is protected from electric shock when touching the normal user-friendly area of the machine. When an insulation default occurs, the tension in the alternator can be interrupted, the engine can be stopped, or an alarm can be activated. In this case, no ground pin is needed!

When and how to repair and maintain the generator set?

First of all, every piece of equipment you buy will have a maintenance schedule, which can be arranged according to the established time. The frequency and type of service required to maintain a PowerLink generator set will depend on a number of factors, including the use of the generator, the operating environment, and the load that needs to be carried. As an owner, it is your responsibility to ensure regular and comprehensive service. You will need frequent visual inspections at least every 2 to 3 months to check that everything is working properly – recording any faults or repairs.

A full service should be performed every 12 months, including filter and lubricant changes, etc. Most boot failures are the result of not testing the device regularly. We recommend that you check the generator once a week.

We have a professional after-sales service team, that can send engineers around the world to provide door-to-door service. The service types include single service, contract-based contract service, or local third-party agency service with certification qualifications, depending on customer requirements.

What happens if I overload the generator?

The generator set should not be continuously overloaded after operation (it is recommended to run at full load), but should be in an overloaded state for a very short period of time, especially during the unit start-up. If a unit has been operating for a long period of time and is in an overload state (i.e. exceeds the maximum rating of the unit), several things can happen.

Which includes:

  • Cooling system overheating.
  • The alternator windings are overheating.
  • The decrease in oil viscosity results in low oil pressure.
  • Shorten the working life of the generator.

All engines are designed to operate under different loads, ranging from maximum to minimum. Problems occur when the light load (minimum load) lasts for a long time, causing the engine to fail to return to its normal operating temperature, and glazing may occur, which means that the oil normally burned in the cylinder is heated and a coat of paint forms on the cylinder liner. If light loading continues, visible blue smoke will appear and the engine will need maintenance work, cleaning or replacement of the lining.

How to purchase spare parts?

We have developed a complete spare parts supply plan for each outgoing product, which is managed by a professional parts sales team. In addition, Powerlink has a convenient online sales platform for accessories purchases. You can also contact your local distributor, or directly contact the factory parts sales staff, we will follow your needs, and the parts can be quickly delivered to your location around the world. We also dispatch professional service engineers to replace parts on site if necessary.
