The fixed boarding bridge hydraulic pump station has the advantages of compact structure, light weight, high efficiency, small volume, reliable performance, no leakage, beautiful appearance, low price and so on. The fixed boarding bridge hydraulic pump station uses mineral hydraulic oil as the working medium. In the process of practical application, in addition to further optimizing the design scheme of the hydraulic pump station and improving its performance, we should also learn the basic operation of the commissioning of the fixed boarding bridge hydraulic pump station to ensure that the hydraulic power unit is always in a normal state, so as to better use the equipment.

 

固定式登车桥土建要求：

 

Civil engineering requirements for fixed boarding bridge:

 

1、用户须严格按照供方提供的安装坑位尺寸图预留好坑位，且方正平直，底面坚实平整。

 

1. The user must reserve the pit in strict accordance with the installation pit size drawing provided by the supplier, and the pit shall be square and straight, with a solid and flat bottom.

 

2、坑位前面两端（即A处）须坚固平整，便于安装防撞胶势。

 

2. Both ends in front of the pit (i.e. position a) must be firm and flat to facilitate the installation of anti-collision glue.

 

3、用户须预先在坑位边缘准备稳车的防撞包边角铁（80#以上），且与土建中钢筋网连接牢固，每个间距不大于300MM。

 

3. The user must prepare anti-collision corner irons (80# above) for vehicle stabilization at the edge of the pit in advance, and connect them firmly with the reinforcement mesh in the civil engineering, with each spacing of no more than 300mm.

 

4、电源要求380V/50HZ，配置一条不小于2.5平方五芯电源线，从电控箱土建坑位内电源出口处，且用钢管或PVC管作保护，电控箱安装位置能看见登车桥动作。

 

4. The power supply shall be 380V / 50Hz, equipped with a five core power line of not less than 2.5 square meters, from the electric control box to the power outlet in the civil pit, and protected by steel pipe or PVC pipe. The boarding bridge action can be seen at the installation position of the electric control box.

 

固定式登车桥液压泵站调试：

 

Commissioning of fixed boarding bridge hydraulic pump station:

 

1、正常情况下在出厂前固定登车桥液压泵站都是调试好的；

 

1. Under normal circumstances, the fixed boarding bridge hydraulic pump station is debugged before leaving the factory;

 

2、用户在使用时应该注意的就是检查泵的旋转方向应与泵体上标牌所指示的方向相符合，三相电源线不得接反；检查液压系统有没有泻荷回路，能否造成满载启动和停车；在常态下，油泵向系统供油，自动保持系统额定压力，通过控制阀的闭锁，实现阀门在任意位置下的保位功能。

 

2. What users should pay attention to when using is to check that the rotation direction of the pump should be consistent with the direction indicated by the label on the pump body, and the three-phase power line should not be connected reversely; Check whether the hydraulic system has load relief circuit and whether it can cause full load start and stop; Under normal conditions, the oil pump supplies oil to the system, automatically maintains the rated pressure of the system, and realizes the position holding function of the valve at any position through the locking of the control valve.

 

3、一般的液压油路，开始都会有一个溢流阀，防止压力过大而破坏了其它元件起保护作用的，一般先调整这个数值，比需要的压力高出0.3就就可以了；

 

3. Generally, there will be an overflow valve in the hydraulic oil circuit at the beginning to prevent the damage of other components due to excessive pressure. For protection, generally adjust this value first, which is 0.3 higher than the required pressure;

 

目前已被广泛的应用于汽车工程、仓储物流、建筑机械、汽保设备、机床机具医,疗器械及生产线控制等行业，也正在逐渐被人们所认识设计选用。

 

At present, it has been widely used in automobile engineering, warehousing and logistics, construction machinery, automobile maintenance equipment, machine tools, medical equipment, production line control and other industries, and is gradually being recognized and selected by people.

 

根据使用场地的不同，登车桥的要求也不同，如果装卸作业是流动的，就选择移动登车桥，反之固定在一定场合，选固定登车桥，这2种登车桥的额定载重基本相同，市场上绝大多数使用载重在6-12T左右，但也有些例外，需要15T，20T，30T，这就需要非标定制。

 

According to the different use sites, the requirements of the boarding bridge are also different. If the loading and unloading operation is mobile, choose the mobile boarding bridge. On the contrary, choose the fixed boarding bridge when it is fixed on a certain occasion. The rated load of the two boarding bridges is basically the same. Most of the used load in the market is about 6-12t, but there are some exceptions. 15t, 20t and 30t are required, which requires non-standard customization.

 

升降平台的工作原理是由液压油由叶片泵形成一定的压力，经滤油器、隔爆型电磁换向阀、节流阀、液控单向阀、平衡阀进入液缸下端，使液缸的活塞向上运动，提升重物，液缸上端回油经隔爆型电磁换向阀回到油箱，其额定压力通过溢流阀进行调整，通过压力表观察压力表读数值。

 

The working principle of the lifting platform is that the hydraulic oil forms a certain pressure from the vane pump and enters the lower end of the hydraulic cylinder through the oil filter, flameproof electromagnetic directional valve, throttle valve, hydraulic control one-way valve and balance valve to make the piston of the hydraulic cylinder move upward and lift the heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the flameproof electromagnetic directional valve, and its rated pressure is adjusted through the overflow valve, Observe the reading value of the pressure gauge through the pressure gauge.
