The guide rail elevator has three advantages. What are the three? Now, let's make up the answer!

（1）土建優(yōu)勢(shì)

(1) Civil engineering advantages

1、井道上方無(wú)需機(jī)房，高度3.5米以上即可安裝。

1. No machine room is required above the hoistway, and the top floor height is more than 3.5 meters.

2、機(jī)房可設(shè)在井道半徑15米的范圍內(nèi)，占有面積僅3-4平方。

2. The machine room can be set within the radius of 15 meters of the shaft, occupying only 3-4 square meters.

3、液壓電梯不設(shè)置對(duì)重裝置,提高井道面積利用率。

3. The hydraulic elevator is not equipped with counterweight device to improve the utilization rate of hoistway area.

4、液壓電梯負(fù)荷、載重通過(guò)油缸直接作用于基坑，井道強(qiáng)度要求低，磚結(jié)構(gòu)或磚混結(jié)構(gòu)井道即可。

4. The load and load of the hydraulic elevator directly act on the foundation pit through the oil cylinder. The shaft strength requirements are low, and the brick structure or brick concrete structure shaft is sufficient.

（2）穩(wěn)定性?xún)?yōu)勢(shì)

(2) Security and stability advantages

1、溢流閥：可防止上行運(yùn)動(dòng)時(shí)系統(tǒng)壓力過(guò)高。

1. Relief valve: it can prevent the system pressure from being too high during upward movement.

2、應(yīng)急手動(dòng)閥：電源發(fā)生故障時(shí),可使轎廂應(yīng)急下降到層樓位置開(kāi)門(mén)。

2. Emergency manual valve: in case of power failure, the lift car can be lowered to the floor position for emergency opening.

3、手動(dòng)泵：當(dāng)系統(tǒng)發(fā)生故障時(shí),可操縱手動(dòng)泵打出高壓油使轎廂上升到層樓位置。

3. Manual pump: when the system fails, the manual pump can be operated to pump out high-pressure oil to make the car rise to the floor position.

4、油箱油溫保護(hù)：當(dāng)油箱中油溫超過(guò)標(biāo)準(zhǔn)設(shè)定值時(shí),油溫保護(hù)裝置發(fā)生信號(hào),暫停電梯使用,當(dāng)油溫下降后方可啟動(dòng)電梯。

4. Oil temperature protection of oil tank: when the oil temperature in the oil tank exceeds the standard setting value, the oil temperature protection device will send a signal, and the elevator will be suspended. When the oil temperature drops, the elevator can be started.

（3）運(yùn)行成本優(yōu)勢(shì)

(3) Operation cost advantage

1、故障率低:由于采用了的液壓系統(tǒng),且有良好的控制方式,電梯運(yùn)行故障率可將低。

1. Low failure rate: due to the advanced hydraulic system and good control mode, the failure rate of elevator operation can be reduced to low.

2、耗電量少:液壓電梯下行時(shí),靠自重產(chǎn)生的壓力驅(qū)動(dòng),大幅度。折疊編輯本段維護(hù)保養(yǎng)導(dǎo)軌式液壓升降機(jī)在日常生活中使用時(shí)要注意保養(yǎng)，延長(zhǎng)它的壽命。

2. Less power consumption: when the hydraulic elevator goes down, it is driven by the pressure generated by its own weight, saving energy greatly. Folding and editing Maintenance in this section Pay attention to maintenance when using the guide rail hydraulic lift in daily life to extend its service life.
