Automatic Voltage Regulation Small Gasoline Generator 5kva 8kva 10kva

Common faults:

Can't power:

(1) Check and correct wiring errors according to the circuit diagram.

(2) The excitation windings of the main generator or exciter are connected incorrectly, resulting in incorrect polarity. It is often caused by wiring error after replacing the excitation winding. It should be checked and corrected.

(3) Rotary silicon rectifier element breakdown short circuit, positive and negative conduction. Use a multimeter to check the positive and negative resistance of the rectifier element and replace the damaged element.

(4) The excitation winding of the main generator is broken. Use a multimeter to check and measure the excitation windings of the main generator. The resistance is infinite and the excitation line should be connected.

(5) The winding of the main generator or exciter has a serious short circuit. The armature winding has a short circuit, which is generally obvious overheating. The short circuit of the excitation winding can be determined by the resistance value of its tributaries. Replace the damaged winding.

The principle of:

A working cycle includes four piston strokes (the so-called piston stroke refers to the distance between the piston from top dead center to bottom dead center) : intake stroke, compression stroke, expansion stroke (work stroke) and exhaust stroke.

Intake stroke:

During this process, the engine's intake valve opens and the exhaust valve closes. As the piston moves from top dead center to dead center, the cylinder volume above the piston increases, so that the pressure in the cylinder drops below the atmospheric pressure, that is, the vacuum suction is caused in the cylinder, so that the air is sucked into the cylinder through the intake pipe and intake valve, and the oil nozzle spray atomized gasoline and air are fully mixed. At the end of the intake, the gas pressure in the cylinder is about 0.075-0.09MPa. The temperature of the combustible mixture in the cylinder has risen to 370-400K.

Compression stroke:

In order to make the combustible mixture inhaled into the cylinder can burn quickly, so as to produce greater pressure, so that the engine emits higher power, must be compressed before combustion, so that its volume is reduced, the density is increased, the temperature is increased, that is, there is a compression process. In this process, the intake and exhaust valves are all closed, and the crankshaft pushes the piston from BDC to DC to move one stroke, that is, the compression stroke. At this time, the mixture pressure will increase to 0.6-1.2MPa, and the temperature can reach 600-700K.

specifiCAT-parts-partsion parameter:

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
