Forklift rocker and bolts

A direct result of poor seal off the engine burning Lpg Gas Forklift oil or petrol filling quality of impurities, then the valve is even more serious and the formation of coke and faster. Because carbon sponge-like structure, when the valve after the formation of coke fuel injected into the cylinder for each part will have to be adsorbed, so that the real concentration of the mixture into the cylinder thinning, resulting in difficulty in starting the engine idle shake, emergency fuel back fire, resulting in excessive exhaust blockage triples, increased fuel consumption and other phenomena.

Valve coke

Coke can cause severe valve closed lax, the cylinder and the cylinder pressure because there is no completely does not work, even blocking the valve so that it does not return. At this valve and piston movement will produce interference, and ultimately damage the engine.
Oil pump strainer is easily clogged coke after filter clogging can cause malfunction due to the low oil pressure light. The following figure shows the oil pump strainer on carbon has been covered, although it is easy to manually remove these carbon deposits, but also for dismantling.

Oil pump chain

As China rough terrain forklift oil industry chief genuine electricity supplier shopping guide platform "Oil cat", relying on Chinese powerful traffic information network platform and team of experts, through professional resource library for consumers to provide effective and direct oil policy recommendations for the user to solve the "genuine oil, on which to buy" problem. Currently, through the "oil cat" oil platform consumer online shopping, buying oil rate of 100% authentic, do not have any complaints occur.

What to buy the truck to pay attention?

1. Operating environment

This is the purchase of the truck primary consideration, outdoor or indoor operation. If forklifts for warehouse outside, to choose gas, liquid petroleum or diesel powered internal combustion engine type Wheel Driving Diesel Forklift ; if the truck is mainly working in the outdoor cold environment, then gasoline-powered forklift is the most reasonable choice. It is worth noting, diesel forklifts should be kept in use, turn off the engine can not always; every few minutes if the user initiates a truck , it will damage the truck ; another suggestion, diesel truck engine oil should be changed regularly.

Another type of truck is mainly designed for outdoor operation, the liquid petroleum - also known as LP-driven, and gasoline fuel type forklift for the market. LP forklift suitable for both indoor and suitable for outdoor use because it is smaller than gasoline exhaust toxicity. LP forklifts and diesel High Mast Diesel Forklift fuel costs are almost the same, but the diesel forklift less maintenance costs. In cold conditions, the user sometimes LP forklift assembly protective cover or heater; if this does not guarantee the truck running, then the LP truck into a gasoline truck is also very easy.

Outdoor environment not only determines the selection of the internal combustion engine, for the use of the tire type is also required. Pneumatic tire suitable for rough terrain; free inflatable tires are suitable for outdoor flat and hard ground, and most indoor applications.

2. indoor warehouse Diesel Rough Terrain Forklift Truck

For indoor handling, such as in warehouses, electric forklifts advantage. And internal combustion forklifts compared to its main advantage is low noise, no pollution. Although electric forklift price than internal combustion forklifts high, but lower operating costs. Electric forklifts are the main reasons for saving money without fuel, there is no need to replace oil and classes of components such as plug and socket. Electric forklift maintenance costs for the normal life cycle, the hour only 2 yuan to 6 yuan (a forklift running one shift a day, about the use of 1700h per year). The use of electric forklift battery must always pay attention to the case, check the water level and avoid battery kill.

Forklift hydraulic mechanical transmission repair

Forklift hydraulic mechanical transmission system is an important part of the vehicle, some of the internal combustion off road rough terrain forklift after prolonged use, hydraulic mechanical transmission system will be some common faults, for example are: output power shortage, difficulty starting, shifting unresponsive; oil temperature is too high and the torque converter does not work.

Failure Analysis

Found in the course of the

electrical forklift

 underpowered, climbing difficulty, shift unresponsive, and load lifting work, the first detection system pressure gauges are available, if less than the required pressure value may be due to: Compensation pumps gear pump for excessive wear, the compensating pump gear pump for excessive wear, so that the increase in the compensation pump leakage; cleanliness bad oil caused oil plug, make compensation sucked empty.

If the oil temperature is too high, the usual reason is: the oil pump oil blockage caused by inadequate compensation amount, the clutch dry friction caused by high oil temperature; adjust the pressure inside the torque converter oil pressure falls below the main pressure valve, so that converter outlet pressure is too low; oil grades wrong; converter damage to internal components of the engine's power is only rarely passed to the turbine part, reactive power is too large and cause a sharp rise in oil.

If viewed from the observation hole of the torque converter to the torque converter does not work, you should first check the oil return into the oil and torque converter, if not back to the oil, and the truck with normal cold and hot cars travel difficulties, the cause of the failure to compensate pump badly worn or damaged; if the torque converter without power output, while sometimes working without work, the cause of the malfunction is the oil plug, inside idler pulley seat or seat cover is damaged nut loosening.

Troubleshooting

As can be seen from the above analysis, the truck's hydraulic mechanical transmission failure is mainly the oil, torque converter and compensation pump these three aspects. Therefore, the first consideration should be to clean up the oil troubleshooting, replacing the oil and oil filter as required; then check the torque converter and compensation pump these three aspects. Therefore, the first consideration should be to clean up the oil troubleshooting, replacing the oil and oil filter as required; then check the torque converter guide wheel, seat and clutch pulley for damage; and finally check the pump to compensate for wear and repair or replace damaged components. Must clean up the oil radiator surface dust and dirt. Were above treatment, generally better troubleshooting.

In the maintenance of transmission lines, should pay attention to the following checks; engine flywheel, the torque converter and shell concentricity error should be less than 0.2mm; dynamic unbalance lands should be less than 30g · cm; the engine flywheel housing face and converter housing relative to its axis of the end face side beat no more than 50UM; there should be a gap between 1.0-1.5mm converter fork and compensation pump gear end.

diesel engine parts spare parts market demand will greatly promote the spare parts

In recent years, global production electric forklift truck and sales growth year after year forklift truck in China's market size. China's economy has accelerated steadily for the better development of the logistics industry, forklift industry growth of China's industrial vehicles best sub-sectors, and has been unprecedented attention. 5 tons off-road forklift trucks By the end of 2012, the Chinese market has reached 1.5 million truck fleet units. The presence of a large number of trucks, will bring strong demand for its accessories.
