取芯勘探鉆機千米鉆機
XY-44A鉆機主要適用于以合金和金剛石鉆進為主的巖心鉆探，也適用于工程地質勘探、水文水井鉆進，以及大口徑基礎樁工程。
XY - 44 a drilling rig is mainly suitable for core drilling is given priority to with alloy and diamond drilling, can also be applied to engineering geological exploration, water well drilling, as well as the large diameter pile foundation engineering.
XY-44A型鉆機的主要特點：
1.具有較多的鉆速級數 （8級），和合理的轉速范圍，低速扭矩大（最大達8000牛頓.米）,既適合以合金、金剛石巖心鉆進，也可用于工程地質勘察，水文水井鉆進和基礎樁工程施工。
2.立軸通孔直徑大（直徑93mm）,雙軸缸液壓給進，行程較長（可達600mm），工藝適應性強，特別適合大直徑鉆桿繩索取心（上部取心）鉆進，有利于提高鉆進效率和減少孔內事故。
3.鉆進能力大，直徑71毫米繩索取心鉆桿額定鉆進深度可達1000米。
4.重量輕，可拆卸性好，鉆機凈重2300千克，主機可分解為10個部件（最大可拆卸部件重300千克），搬遷方便，宜于山區(qū)工作。
5.液壓卡盤采用單向供油，卡盤加持力大，加持穩(wěn)定。
6.配有水剎車，深孔鉆進，下鉆平穩(wěn)安全。
7.采用單聯齒輪油泵供油，安裝簡便，方便使用，功率消耗少，液壓系統(tǒng)油溫低，工作穩(wěn)定。系統(tǒng)中裝有手搖油泵，當動力機不能工作時仍可用手搖油泵起出孔內鉆具。
8.鉆機結構緊湊，布局合理，所有部件表露在外，不相互重疊，便于維護、保養(yǎng)和修理。
9.重心低，移車距離長（可達460mm），固定牢靠，高速鉆進穩(wěn)定性好。
10.配有仿震儀表，儀表壽命長，利于掌握孔內情況。操縱手把較少，操作靈活可靠。通用化程度高，該機與XY-4A型鉆機通用件達60%，與XY-2型鉆機通用件達75%。
The main characteristic of XY - 44 type a rig:
1. With more drilling rate series (8), and reasonable speed range, low speed torque (maximum 8000 Newton. M), suitable for both with alloy, diamond core drilling, also can be used in engineering geological exploration, water well drilling and pile foundation construction.
2. The vertical shaft hole diameter (93 mm) in diameter, biaxial cylinder hydraulic feed, a longer stroke (600 mm), process adaptability is strong, especially suitable for large diameter pipe rope coring (upper) of coring drilling, to improve drilling efficiency and reduce the hole accident.
3. The drilling capacity big, wireline coring drill pipe nominal diameter of 71 mm drilling depth of up to 1000 meters.
4. Light weight, good removable, rig net weight 2300 kilograms, the host can be decomposed into 10 parts (maximum removable parts weighs 300 kilograms), convenient move, like mountain work.
5. Hydraulic chuck used one-way fuel supply, chuck blessing strength and stability.
6. Equipped with water brake, deep hole drilling, drilling a smooth and safe.
7. Using single gear oil pump oil supply, installation is simple, easy to use, less power consumption, low hydraulic oil temperature, stable work.Hand pump, are installed in the system when the engine can't work still manually operated pump up out of the hole drilling tools.
8. Drill compact structure, rational layout, all the parts show in the outside, not overlapping, easy to maintain, maintenance and repair.
9. Low center of gravity, move the car distance (up to 460 mm), fixation, high speed drilling stability is good.
10. Equipped with seismic instrument, instrument long life, to grasp the hole.Manipulation of the handle is less, flexible and reliable operation.Generalization degree is high, the machine type and XY - 4 a drill part of 60%, with XY - type 2 drill part is up to 75%.
