Portable Compact Gasoline Generator Forced Air Cooling 110/220V

Portable Compact Gasoline Generator Forced Air Cooling 110/220V

common fault:

The no-load voltage is too high:

(1) Automatic voltage regulator is out of control. The excitation winding current of no-load exciter is too large. Check the automatic voltage regulator.

(2) The setting voltage is too high to reset the voltage.

Excitation current of exciter:

(1) The rectifier element has one or two components in the positive and negative circuit, check with a multimeter, replace the damaged components.

(2) The main generator or exciter part of the excitation winding short circuit, measure the DC resistance value of each pole coil. Replace the coil with a short circuit fault.

Steady-state voltage adjustment rate:

Automatic voltage regulator has a fault check and troubleshoot.

High vibration:

(1) Poor docking with prime mover check and correct docking. After the bolts are fastened, ensure that the generator and the prime mover axis are straight and concentric.

(2) The rotor dynamic balance is not good, occurs after the rotor is rewound, should find the positive dynamic balance.

(3) Short-circuit of the excitation winding of the main generator measure the DC resistance of each pole and find out the short-circuit fault point. Replace the coil.

(4) Bearing damage, generally bearing cover overheating phenomenon, replace the bearing.

(5) If the prime mover is faulty, check the prime mover.

overheating:

(1) The generator is overloaded, so that the load current and voltage do not exceed the rated value.

(2) The load power factor is too low, adjust the load, so that the excitation current does not exceed the rated value.

(3) If the speed is too low, adjust the speed to the rated value.

(4) There is a short circuit in some windings of the generator. Find out the short circuit and correct or replace the coil.

(5) The air duct is blocked, the obstacles are removed, the motor is dismantled, and the air duct is thoroughly blown.

Product Description:

Since establishment in 1985, Guangdong ALI Testing Equipment Co., Ltd, a wholly-owned subsidiary of GSKA Group has been providing a wide and complete range of products and services to the society. GSKA has now 16 offices, warehouses and service centres in China, with head office loCAT-partsed in Hong Kong. There are more than 100 employees in GSKA Group, and we are expanding into many industries with rapid expanding pace of China.

There are mainly 4 departments in GSKA Group, namely:

1) Construction and Mining equipment

GSKA has been cooperating with many international famous brands in China, such as Ingersoll-rand, Atlas Copco and Liebherr. Our products include concrete batching plants, concrete mixers, hydraulic crawler drills, pneumatic crawler drills, water well drills, air compressors, road compactors, breakers and various other equipment. We are major in several industries, such as hydro-electric power plants, cement quarries, coal mines and railway systems.

In order to provide a quick response to our customers, we have stocked over US$1.5 Million spare parts of Ingersoll-rand and Atlas Copco in our Chinese warehouse. Recently, we have exported small air compressors, pneumatic crawler drills, water well drills and drilling accessories and spare parts to overseas market.

2) Power Group

GSKA has been supplying CAT-parts and Broadcrown gensets for more than 15 years. Our major customers include Telecoms, Banks, Airports, Factories and many other sectors in the society. We are also doing assembly of gensets in China, under our brand name of "GSKA " with ratings from 1KVA to 2000KVA. The quality of "GSKA " genset has won a very good reputation from customers in China and overseas market.

We are also the specialists for genuine spare parts, such as CAT-parts, Perkins, FG Wilson, Cummins, , Volvo, etc.

Besides gensets, we also provide total solution on the power problems, such as Powerware - UPS, DC system and battery ,lightning equipment and many other electronic products.

3) Security and IT Group

GSKA acquired famous USA brand name Locktronix in 2004 and started manufacture electric locks in China. Since then, we have been exported products to the Middle East, South Asia and Africa. Our market is expanding each year and we are looking for more distributors in different countries to be our business partners. Besides electric locks and accessories, we have also developed our own access control system by our software team. The system includes smart card solution and also biometric access control, such as hand-key, fingerprint and facial recognition. Our EC-PAYROLL system has been widely used in many factories both in Hong Kong and mainland China.

After all, GSKA has an objective of "Always Provide the Best" and we shall consistently provide high quality products and reliable services to our worldwide customers. We are looking forward to making good business with our partners
