Electric forklift repair troubleshooting and maintenance method

Electric forklift repair troubleshooting and maintenance methodAs the use time of the electric forklift is increasing and the effects of various factors such as environmental and driver operation during use, the forklift mechanism and each of the spare pieces can produce different degrees of natural loose or wear, and the quadrant And mechanical damage. In use and maintenance, it will also cause serious abnormal abnormal wear, which is destroyed by the normal cooperation relationship of the electric truck fitting.

Different parts of the part, natural corrosion, loose fasteners, and the relevant partial adjustments are incorrect, which will destroy the original technical state of the electric forklift machine. When the technical state is deteriorating to a certain extent, it is inevitable that some degree of abnormal phenomenon or some spare parts lose work ability, so that the machine can continue to work, this phenomenon is called mechanical failure. When the mechanical components of the electric forklift have failed, through analysis, judgment, and adopt the necessary method, it is found that the occurrence of the fault occurs, and the exclusion is given, and the fast recovery of the intact technology is called electric forklift repair.

Industrial forklifts are used in many industries. Due to the continuous advancement of technology, the battery-driven industrial forklift becomes more common. With longer driving time, shorter charging time and less emissions (this actually eliminates the risk of carbon monoxide), this type of forklift becomes more popular. For example: forklift lithium battery. Currently, there are a variety of types of batteries that drive forklifts from small electric tray to greater high-rise forklifts. No matter what kind of electric industrial forklift you have, their batteries and maintenance have similar dangers. Electric industrial forklifts are driven by large lead-acid batteries, and they must be charged and replaced regularly.

Electric forklift sound abnormal cause and repair method:

1, the fastener screws are loose, the vehicle body guide and the roller have a serious wear, and the gap is too large.

2, the chain and chain pins are too large or on the fork, and the lower jack and the fork are too large.

3, check the guide wheel, the conflict roll gap between the roller and the door frame is too large. The cooperation voids between the fork and fork beam are too large, and these factors will cause the electric forklift to have an abnormality when using.

4, check if the tire screw is loose, whether the bearing is damaged, and so on.

5, the forklift gear pump fails, such as the air entering the pump from the suction pipe or seal, the resistance of the oil absorbing tube is too large, even partially clogged. The gear pump is not high. Pumps and couplings different axes. The solution has a lubricant oil in the connection. If the abnormal decrease is revealed, tighten the joint or direct replacement seal; if there is no change, check the gear accuracy, perform the ground and adjustment, and replace the gear when necessary. Finally, check the coaxial degree of the pump and the coupling, pay attention to the working state and the stationary state, and adjust it according to the technical requirements.

The reason for the forklift is very much, the forklift maintenance personnel should open the forklift to the parking lot facility for special investigation, so that the reason why the fork car is resolved from the source of the forklift can solve this fault directly.

Electric forklift working device and hydraulic system failure and repair method

1. The main reason for the trend is mainly: there is air, hydraulic system oil, the inner door frame fork size roller and

The gantry bearing is overwear, and the two lifting chains are equal.

2, the lifting speed is too slow or cannot be lifted. Mainly, the fuel tank is deficit, the oil filter is blocked, the safety valve failure, the hydraulic oil temperature is too high, the hydraulic oil is too thin, the hydraulic pipeline oil, the hydraulic pump is damaged, and the like. There is an abnormal housing decline, which is generally shockproof, damage or aging. The maintenance method is first to check each of the joints, all component seals, and the inside of the structure, if there is, replace it; give the system, if it is still not excluded, it is necessary to remove the booster cylinder, gear pump and The work of the safety valve is not reached, and it is required to be trimmed or replaced.

3, lifting and jump, now the starting gantry beating phenomenon. The cause of the fault causes air in the lifting cylinder; the gear pump is poor; the forklift is reversed and the valve is not flexible; the oil is not clean. The maintenance method is to release the flex rush on the lifting cylinder cylinder, and the air in the liter cylinder will be released; the oil cleanliness is checked. If you still can't clear the beating, you have to check the working conditions of the commutation valve and gear pump, such as poor working, should be repaired or replaced.

Other faults and maintenance methods

1. The free decline is too fast when there is a load, mainly: pipelines and joints with leakage or multi-channel valve stem or seal wear

Introduction, lifting cylinder piston sealing seal, resulting in an intake, etc.

2, the front and rear tire screws are loose, the hub bearing is damaged, the rear bridge plane bearings and roller bearings are damaged, and there will be abnormalities during driving.

3, the abnormality of all parts of the whole car must be eliminated one by one, and then test the problem and find a reasonable maintenance process after discovering the problem, and solve the problem.

4, the brake runs. This fault cause is that the braking force of the left and right wheels is uneven, so that when the fork is braked, the brake gap or master cylinder is to check which side when braking. There is no regularity, and if the left is right, if the brake is moved to the left and then right, you should first check the left wheel brake, and then check the right wheel. Finally, the brake shoe friction or the brake drum has oil.

5, oil leakage (including leakage, inner leakage). Master cylinder, wheel cylinder oil leakage, most of which is due to skin bowl, and the lap time is too referred to as wear. If you feel light when you step on the brake pedal, it is generally the main cylinder kitwear. Oil leakage; the brake hoof flake is too thin or the brake gap is too large. When stepping on the brake pedal, the wheel cylinder leather bowl is often turned into oil.

6. Excessive consumption of forklift brakes.

1) Check if each line is oil leak.

2), the brake spool in the truck transmission shifting the brake slider leak oil, but causes the brake fluid into the transmission, at which point the hole can smell the odor of the brake fluid from the transmission oil.

3) Vacuum supercharger booster cylinder piston kitchen, sealing ring or piston push rod seal and control valve skin bowl, which will cause excessive brake fluid consumption.

7, press the brake pedal very laborious. Cause: The main cylinder kitchen or the main tank piston is bloated. The copper tube between the master cylinder and the supercharup is deformed or clamped, which makes the inner hole small, and the oil is not smooth. The copper tube of the wheel cylinder is deformed, causing a small pore size, and the oil is not smooth. The control cylinder seal is swollen, the brake fluid is deteriorated, and the fluidity is deteriorated.  Recommend: LiFePO4 Battery Manufacturer Energy storage battery Manufacturer Integrated machine energy storage battery series Manufacturer Lead lithium battery Manufacturer Outdoor Backup Battery Manufacturer Portable outdoor power supply Manufacturer Power battery Manufacturer Powerwall LiFePO4 Battery Manufacturer Battery rack Manufacturers Telecom LiFePO4 Battery Manufacturer Wall mounted battery storage Manufacturer China Lifepo4 Battery
