Oil cylinders and oil pumps are the core components of many hydraulic equipment. For example, many users of manual hydraulic pallet trucks have malfunctioned due to improper operation during use. But I don't know where the fault is. When we use the manual hydraulic pallet truck, the problem we often encounter is that the fork cannot rise. At this time, the cause of the failure is most likely the cause of the oil pump. Below, I will analyze the relevant knowledge about the oil cylinder and oil pump of the truck so that you can better deal with the problem of the truck failure.
Cylinder: The cylinder plays a key role in the lifting of the truck. The lifting of the goods is also realized by it. If the fork cannot be lifted, it is very likely that there is a problem with the cylinder.
When the cargo is overweight or the cargo is not placed in the middle position, the piston rod in the oil cylinder or the oil cylinder is seriously damaged.
When not in use, the piston rod is exposed to the outside for a long time, causing rust and making the piston inflexible. Check and judge the situation and replace the cylinder or piston rod.
Oil pump: This is also a key component in all hydraulic equipment. For example: manual hydraulic pallet truck. As long as the oil pump fails, the entire pallet truck cannot be used. As long as any component of the oil pump is found to be damaged, it must be replaced immediately, such as : Sealing ring, steel ball, dustproof ring, etc., if not replaced in time, it may damage the entire oil pump.
Oil seal: The part that makes the connection between the cylinder tube and the piston rod airtight is the oil seal. This part is generally an imported seal ring because it has good sealing performance and wear resistance. I often see many people on the Internet Ask the problem of oil leakage in the cylinder. The possibility of this cause appearing on the oil seal is very high. It is recommended that if there is an oil leakage problem, you can check the oil seal.
