Most users fail to pay attention to the normal operation rules when using the manual hydraulic transporter, but they don't know what causes the failure. We know that the reason why the fork of the pallet truck can't rise will be handled in time when problems arise. The manual hydraulic transporter plays a role in the whole process of transporting. Replaceable role, so we must pay attention to maintenance in the use process, so that we can greatly improve the efficiency of our work. The following are common failures and solutions of manual hydraulic transporter:
1. Fork of Manual Hydraulic Transport Vehicle Can't Drop Down
Cause analysis: the pressure relief valve is not adjusted, the piston rod position of the cylinder is offset, and parts are damaged or deformed due to offset load.
Solution: Remove the positive pressure valve, replace the piston rod or cylinder, repair or replace related parts
2. Fork slides without pressure relief
Reason analysis: There is air in hydraulic oil, impurities in hydraulic oil, the pressure preventer is not adjusted properly, and the seal is damaged.
Solutions: Air removal, replacement of clean hydraulic oil, regulation of pressure relief valves, replacement of new seals
3. The fork of the transport truck can't be lifted.
Reason analysis: impurities in hydraulic oil, pressure relief valve not adjusted properly, air in hydraulic oil
Solution: Replace clean hydraulic oil, adjust pressure relief valve, remove air in oil pump
4. Oil Leakage of Carrier
Cause Analysis: Wear or Damage of Seals, Cracking or Wear of Parts
Solution: Replace new seals and check for updated parts
5. Lifting not up to standard
Reason analysis: There are impurities in hydraulic pressure, which can not be closed by using one-way valve.
Solution: Replacement of Pure Hydraulic Oil
6. Crawling without Load
Cause analysis: deformation of door clamp and tightening of cylinder sealing ring make the resistance of plunger rod too large
Solution: Correct adjustable screw of gantry or adjusting roller axle, adjust upper nut of cylinder
7. Lift slowly or crawl
Cause analysis: hydraulic system severely punishes leakage, sealing ring aging or damage, air in hydraulic system
Solution: Tighten oil release adjustable screw to replace sealing ring, remove air in order to prolong the service life of equipment.
We should do the following:
1. Manual hydraulic stacker should be used on hard and smooth pavement to prevent collision with steel plate, corners and other materials damaging the wheels. It is not necessary to use fork to impact the cargo stack. During the process of loading, there is no standing person nearby. The cargo should be laid down after maintenance and adjustment.
2. When using hydraulic stacker truck in other occasions or conditions, it should be carefully operated and correctly operated to ensure the safety of operation.
3. Troubleshooting of manual hydraulic stacking truck is related to the condition of whether the stacking truck can work continuously. We often learn the common troubleshooting methods of manual hydraulic stacking truck.
4. Before using the equipment, the vehicle should be inspected and maintained as necessary, with emphasis on wheels and mandrels, introduction to door clamps, flexible rotation of joint screw and bearing position, timely cleaning and filling of lubricants.
5. The fork of the stacker should not be manned, and it is forbidden to stand under the fork. In the process of handling, the height of the fork off the ground should not be higher than 300 mm. The goods should be placed between the forks, and the position of the center of gravity of the goods should be strictly controlled.
Users are responsible for the proper maintenance and operation of the tray wheel during the use of Chinese medicine, so as to avoid the wheel or equipment damage caused by improper operation or equipment, high-speed driving on rough road or loading wheels at noon.
Wheels: Visual measurement of wheel wear and tear, poor rotation of wheels is related to pink, rope and other debris. Property should be able to block the winding of these debris, casters to avoid unstable rotation. After checking and replacing the wheels, it is necessary to ensure that the forbidden axle on the lock gasket and nut is used, because the loosening of the wheel axle will lead to spoke and nail rubbing. In case of rubbing and stuck, wheels and bearings should be replaced in time to avoid economic losses caused by shutdown. Casters: If frequent movement steering is too loose, it should be replaced immediately. For example, the rivet of Lunjiao Center is fixed with nuts, it must be firmly locked. If the movement steering cannot rotate freely, it should check whether there is corrosion or stolen goods on the ball. If fixed casters are equipped, the bracket must be ensured that there is no sign of bending.
Lubrication: Manual platform car should add lubricant regularly, tray truck casters and movable bearings can be used for a long period of time. It can reduce friction and rotate more flexibly by applying high-quality lubrication to the friction parts of wheel axles, sealing rings and ball bearings. Lubrication should be carried out every six months under normal use.
