The lifting platform will use pipelines in the process of use, which is the general name of the hydraulic pipe that transmits the working fluid. However, we do not use it casually when we use it, but we must have certain requirements to extend it. Service life, so what are the requirements for the use of pipelines on the lifting platform?
1. Sufficient strength and toughness to ensure that the appropriate flow of liquid is transmitted under the specified pressure and strength without rupture.
2. Corrosion resistance to prevent oil pollution.
3. Select an appropriate size. Under the condition that the flow rate is constant, if the inner diameter of the pipe is too small, the flow velocity of the working liquid in the pipe is high, the pressure drop and friction loss are large, it is easy to generate heat, and the efficiency is low. 4. The pipe should be as short as possible, the bending angle should be as small as possible, and the joints and accessories should be as few as possible. In order to reduce the pressure loss and leakage probability, the high pressure pipe and ultra high pressure pipe should be close to the working mechanism.
5. An air release device should be provided at the high point to release the air in the system.
6. The resistance of the suction pipe should be small, the channel should be unobstructed, and it should be well sealed to prevent the hydraulic pump from evacuating or generating cavitation. Otherwise, the hydraulic pump will have noise, wear and abnormal conditions, and it will cause the hydraulic system to vibrate and not move Stable situation.
7. In order to reduce the local pressure loss, the local expansion or contraction of the cross section and sharp bending should be avoided everywhere in the pipeline.
