Cause analysis of unstable lifting of hydraulic lifting platform

熟悉液壓舉升平臺(tái)的人都應(yīng)該知道，當(dāng)液壓舉升器舉升不穩(wěn)定時(shí)，從現(xiàn)場(chǎng)使用的角度來(lái)看，煙包經(jīng)常打滑，舉升位置難以察覺(jué)，中間位置找不到，舉升有噪音、漏油等現(xiàn)象。

Anyone familiar with the hydraulic lifting platform should know that when the hydraulic lifting device is unstable, from the point of view of on-site use, the cigarette bag often slips, the lifting position is difficult to detect, the middle position can not be found, and the lifting has noise, oil leakage and other phenomena.

現(xiàn)場(chǎng)檢查主要是由于液壓快速升降，導(dǎo)致故障率增加，嚴(yán)重影響生產(chǎn)效率，升降不穩(wěn)的原因很多，具體如下：

The on-site inspection is mainly due to the rapid rise and fall of hydraulic pressure, which increases the failure rate and seriously affects the production efficiency. There are many reasons for the unstable rise and fall, as follows:

針對(duì)液壓舉升平臺(tái)系統(tǒng)故障，運(yùn)用速度理論分析液壓舉升不穩(wěn)定的原因：

Aiming at the failure of hydraulic lifting platform system, the causes of hydraulic lifting instability are analyzed by using speed theory:

(1)提升液壓回路、油泵溢流閥、換向閥、換向閥(無(wú)節(jié)流)和增壓缸的組成。

(1) Composition of lifting hydraulic circuit, oil pump overflow valve, reversing valve, reversing valve (without throttling) and booster cylinder.

(2)做好提升回路的剛度研究，進(jìn)入液壓系統(tǒng)的總流量，即單向總流量公式是通過(guò)的總流量;液壓油的形狀和粘度以及其他相關(guān)系數(shù)，

(2) Do a good job in the stiffness research of the lifting circuit, and the total flow into the hydraulic system, that is, the total flow through the one-way total flow formula; Shape and viscosity of hydraulic oil and other correlation coefficients,

根據(jù)分析，我們很容易得出以下結(jié)論：

Based on the analysis, we can easily draw the following conclusions:

當(dāng)負(fù)載保持不變時(shí)，節(jié)流閥口入口越小，系統(tǒng)越高;相反，如果閥門的開(kāi)啟面積較大，則較低。

When the load remains unchanged, the smaller the throttle inlet, the higher the system; On the contrary, if the opening area of the valve is large, it is low.

負(fù)荷保持不變時(shí)，低速下硬度好，負(fù)荷變化時(shí)，小時(shí)率剛好。

When the load remains unchanged, the hardness is good at low speed, and when the load changes, the hourly rate is just right.

(3)供油壓力加大，液壓缸功能面積大，可提高硬度。

(3) The oil supply pressure is increased, and the functional area of the hydraulic cylinder is large, which can improve the hardness.

綜上所述，很多設(shè)備故障都與液壓有關(guān)，液壓電梯故障的主要原因是液壓系統(tǒng)升級(jí)和調(diào)速回路設(shè)計(jì)不合理，小編認(rèn)為這方面要引起相關(guān)公司的重視，不要等到事故發(fā)生才后悔，得不償失。

To sum up, many equipment failures are related to hydraulic pressure. The main reason for the failure of hydraulic elevator is the unreasonable design of hydraulic system upgrade and speed regulation circuit. Xiaobian believes that this aspect should be paid attention to by relevant companies. Don't wait for the accident to regret, and the gain is not worth the loss.

那么我們?nèi)绾问褂靡簤荷灯脚_(tái)呢?

So how do we use the hydraulic lifting platform?

1.啟動(dòng)前，需仔細(xì)檢查液壓升降平臺(tái)各部件，檢查螺絲連接是否可靠，液壓管路部件是否有泄漏，電線連接點(diǎn)是否松動(dòng)或損壞。

1. Before starting, carefully check the components of the hydraulic lifting platform, check whether the screw connection is reliable, whether the hydraulic pipeline components have leakage, and whether the wire connection points are loose or damaged.

2.提升液壓升降臺(tái)前，將四個(gè)角放在支點(diǎn)上，四條支撐腿牢牢固定在堅(jiān)實(shí)的地面上，桌面調(diào)整為水平(只需目測(cè))，然后檢查所有零件的正常位移后開(kāi)始工作。

2. Before lifting the hydraulic lifting table, put the four corners on the fulcrum, firmly fix the four support legs on the solid ground, adjust the table to be horizontal (only visual inspection), and then check the normal displacement of all parts before starting to work.

3.進(jìn)入平臺(tái)后，關(guān)閉護(hù)欄門，插入螺栓，系好繩，中間載荷(人站的座位)盡可能位于控制臺(tái)中間。

3. After entering the platform, close the guardrail door, insert the bolt, fasten the rope, and the middle load (the seat of the human station) shall be located in the middle of the console as far as possible.

4、作業(yè)時(shí)嚴(yán)禁液壓平臺(tái)超載，平臺(tái)人員在起落下降時(shí)不得移動(dòng)。

4. During operation, it is strictly prohibited to overload the hydraulic platform, and the platform personnel shall not move when taking off and falling.

5、牽引液壓平臺(tái)時(shí)，收好支腿，將平臺(tái)降較低位置，嚴(yán)禁在高處移動(dòng)平臺(tái)。

5. When towing the hydraulic platform, close the outrigger and lower the platform to a lower position. It is strictly prohibited to move the platform at a high place.
