固定式登車橋液壓泵站具有結(jié)構(gòu)緊湊，重量輕，效率高，體積小，性能可靠，無泄漏，外形美觀，價位便宜等優(yōu)點。固定式登車橋液壓泵站采用礦物液壓油作為工作介質(zhì)，在實際應(yīng)用過程當(dāng)中，除了要進(jìn)一步優(yōu)化液壓泵站的設(shè)計方案，提高本身性能以外，還要學(xué)會固定登車橋液壓泵站調(diào)試的基本操作，保證液壓動力單元始終處于正常狀態(tài)，才能更好的進(jìn)行使用設(shè)備。

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.

固定式登車橋土建要求：

Civil engineering requirements for fixed boarding bridge:

1、用戶須嚴(yán)格按照供方提供的安裝坑位尺寸圖預(yù)留好坑位，且方正平直，底面堅實平整。

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、坑位前面兩端（即A處）須堅固平整，便于安裝防撞膠勢。

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、用戶須預(yù)先在坑位邊緣準(zhǔn)備穩(wěn)車的防撞包邊角鐵（80#以上），且與土建中鋼筋網(wǎng)連接牢固，每個間距不大于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、電源要求380V/50HZ，配置一條不小于2.5平方五芯電源線，從電控箱土建坑位內(nèi)電源出口處，且用鋼管或PVC管作保護(hù)，電控箱安裝位置能看見登車橋動作。

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.

固定式登車橋液壓泵站調(diào)試：

Commissioning of fixed boarding bridge hydraulic pump station:

1、正常情況下在出廠前固定登車橋液壓泵站都是調(diào)試好的；

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

2、用戶在使用時應(yīng)該注意的就是檢查泵的旋轉(zhuǎn)方向應(yīng)與泵體上標(biāo)牌所指示的方向相符合，三相電源線不得接反；檢查液壓系統(tǒng)有沒有瀉荷回路，能否造成滿載啟動和停車；在常態(tài)下，油泵向系統(tǒng)供油，自動保持系統(tǒng)額定壓力，通過控制閥的閉鎖，實現(xiàn)閥門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、一般的液壓油路，開始都會有一個溢流閥，防止壓力過大而破壞了其它元件起保護(hù)作用的，一般先調(diào)整這個數(shù)值，比需要的壓力高出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;

目前已被廣泛的應(yīng)用于汽車工程、倉儲物流、建筑機(jī)械、汽保設(shè)備、機(jī)床機(jī)具醫(yī),療器械及生產(chǎn)線控制等行業(yè)，也正在逐漸被人們所認(rèn)識設(shè)計選用。

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.

根據(jù)使用場地的不同，登車橋的要求也不同，如果裝卸作業(yè)是流動的，就選擇移動登車橋，反之固定在一定場合，選固定登車橋，這2種登車橋的額定載重基本相同，市場上絕大多數(shù)使用載重在6-12T左右，但也有些例外，需要15T，20T，30T，這就需要非標(biāo)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.

升降平臺的工作原理是由液壓油由葉片泵形成一定的壓力，經(jīng)濾油器、隔爆型電磁換向閥、節(jié)流閥、液控單向閥、平衡閥進(jìn)入液缸下端，使液缸的活塞向上運(yùn)動，提升重物，液缸上端回油經(jīng)隔爆型電磁換向閥回到油箱，其額定壓力通過溢流閥進(jìn)行調(diào)整，通過壓力表觀察壓力表讀數(shù)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.
