Along with the progress of The Times, the heavy machinery to replace a lot of manpower, elevator industry rapid rise, all kinds of elevator has on the market, so it’s essential to choose a good factory, to avoid late to bring all kinds of after-sales problems, a lot of friends in soybean discussion buy back lifting oil cylinder is ringing, for everybody below the oil cylinder of hydraulic lift platform ring what is going on.
The design of hydraulic lifting platform is unreasonable
The designer in the design of the cylinder cylinder and piston rod, design size Angle and other problems, then the late will certainly be a problem. So in the purchase of hydraulic lifting platform, confirm the technical strength of the manufacturers is very necessary.
Production and assembly of hydraulic lifting platform.
If the machine is not made in strict accordance with the designer’s design drawings, the Angle of the cylinder is slightly deviated, which will lead to the friction between the cylinder cylinder and the piston rod, resulting in the sound.
Three, hydraulic lifting platform seal quality
Using different may also affect oil cylinder ring, seal materials continuously for a good seal and cylinder wall friction will result in a loud voice, and wear for a long time, may will lead to the oil cylinder wall abrasion, so at the time of purchase of hydraulic lift platform should pay attention to ask what material factory use of what brand of seal.
Four, mechanical run-in
Some cases do not rule out the above three cases are normal, or there will be noise, if there is really no problem after the investigation, then do not worry, then do not worry, it is just the running in between the mechanical parts, more than a few times, the sound will automatically disappear.
To sum up, no matter what the situation is, the sound of the oil cylinder is very loud, or it is recommended to contact the manufacturer for cause investigation in the first time, the oil cylinder is in the whole hydraulic system or a relatively important part, do not disassemble the oil cylinder, very dangerous.
