只有当固定式升降机http://www.jnmgsjx.com/带负荷不能启动时，才应该检查液压系统压力，如果压力低于正常范围，才能调整溢流阀设定值。但是有些客户在固定式升降机运行变慢时，为了能让设备加速运转而自行调整设备的出厂设置，这是不太可取的，在设备速度出现变化时，一定要与升降机厂家取得联系，济南美格斯升降机械会派专人给您调试，或通过电话指导，请您暂不可自己调整设备的设置。
The hydraulic system pressure should be checked only when the load is not started, if the pressure is lower than the normal range, the relief valve setting value can be adjusted. But some customers in the fixed hoist running slow, in order to allow the device to run at a higher speed and adjust equipment factory settings. This is less desirable, in the speed of the device when there is a change, be sure to get in touch with the elevator manufacturers, Jinan Meigs lifting machinery will send someone to your debugging, or by telephone guidance, please temporarily not adjust the equipment settings. 

固定式升降机http://www.jnmgsjx.com/购入使用后，由于使用不当或老化、污物使升降机产生了速度变慢的现象。固定式升降机速度变慢后，先考虑液压油流量的因素。影响液压油流量的因素有：液压管路、液压阀、液压油泵、电动机调速装置等。固定式升降机的溢流阀不可自行调整，出现问题请及时与厂家进行沟通，以免造成您的经济损失。
Fixed hoist purchased after use, because of improper use or aging, lifts the dirt produced slow phenomenon. Fixed hoist speed slow, first consider the factors of hydraulic oil flow. The factors that affect the flow of hydraulic oil are: hydraulic pipeline, hydraulic valve, hydraulic pump, motor speed control device, etc.. Fixed lift of the relief valve can not be adjusted automatically, there is a problem with the manufacturers to communicate in a timely manner, so as not to cause your economic losses.
