升降货梯厂家认为，升降货梯的液压部分混入空气对设备是不利的，应该清楚混入空气的原因，在使用过程中多加预防。我们首先要明确混入空气的几个可能性的原因。Elevator goods ladder manufacturers believe that the lifting of the hydraulic part of the cargo ladder into the air is unfavorable to the equipment, it should be clear that the reasons for mixing with the air, in the course of the use of more prevention. We first have to clarify the reasons for the possibility of mixing with air.
 
1.液压升降货梯油箱中油面过低或升降平台吸油管未埋入油液下面造成吸油不畅而吸入空气。Oil hydraulic cargo lift tank is too low or the lifting platform without the oil suction pipe below the suction caused by poor air inhaled.

2.油泵吸油管处的滤油器被污物堵住或者是滤油器出现了问题，导致出现吸油不畅形成局部真空。The oil filter at the oil pump suction pipe is blocked by dirt or oil filter, which leads to the formation of local vacuum.

3.液压升降货梯油箱中吸油管与凹油管相距太近，搅拌油液产生气泡，气泡未来得及消泡就被吸入。Hydraulic lift cargo ladder in the oil suction pipe and the oil pipe is too close to the ground, stirring oil bubbles, bubbles have not been able to bubble when inhaled.

4.升降货梯间油管在油面以上，当升降平台停机时，从问油管逆流而入(缸内有负压时)。Lifting elevator between the tubing on the oil surface, when the lifting platform is stopped, asked from (cylinder and countercurrent tubing negative pressure).

5.升降货梯各油管接头，阀与阀安装板的连接处密封不严，或因振动、松动等原因，空气乘隙混入。The lifting elevator pipe joint sealing connection valve and valve mounting plate, or because of vibration, loosening and other reasons, by the mixed air.

6.升降货梯厂家 http://www.rgsjpt.com/认为，密封被损、老化变质或因密封质量差，是液压系统混入空气的重要原因。Elevator goods ladder manufacturers believe that the seal is damaged, deterioration or poor quality due to poor sealing, hydraulic system is an important cause of air mixed.
