How to solve the noise problem of the lifting platform The operation of the machine will always be accompanied by a certain noise problem, some of which are because the space is too small, the sound in the confined space will increase, and the most common reason is that the lifting platform has been used for a long time, and the hydraulic pump station is aging The noise problem caused by the above reasons. In addition to the above reasons, the failure of the elevator may also produce noise, so how to solve or reduce these noise problems? First of all, let’s take a look at the noise problem caused by the structural failure of the lifting cage
platform: the lack of lubricant in the bearing of the lifting platform causes the vibration and friction between the guide rail and the pulley to increase, resulting in huge noise. At this time, you only need to increase the lubricant or replace the worn out. The roller bearings can be used. platform hydraulic system The second point is how to solve the noise generated by the hydraulic system. The hydraulic system is divided into hydraulic pumps, hydraulic valves and pipes. When the hydraulic system of the elevator is just installed, the noise generated by the motor hydraulic pump will be relatively loud at the beginning of operation, and this phenomenon will not occur after a period of warm-up operation; If the noise is generated in the hydraulic cylinder of the elevator, the hydraulic oil is mixed with air due to the operation error of the elevator changing the hydraulic oil. At this time, the hydraulic oil must be replaced and the hydraulic oil still on the pump should be exported. Check the relief valve. The degree of damage should be replaced in time. The above two situations are the common causes of noise from the lifting cage platform. It is recommended that customers perform daily maintenance and repair every quarter to prevent excessive damage to the elevator and cause unnecessary losses. 134.
