LBSC-400 Fully Automatic Pressurized Core Sampling Machine for Rock Cores Using Liquid Nitrogen

Name: LBSC-400 Fully Automatic Pressurized Core Sampling Machine for Rock Cores Using Liquid Nitrogen
Brand: Laibote (Tianjin) Testing Machinery
Availability: InStock

This machine features a double-column support and a fully sealed design, ensuring that the extracted core samples are more complete and accurate while promoting environmentally friendly operation. The drilling speed is controlled by a variable-frequency drive, addressing the previous drawbacks of the DC180 motor—namely, its slow speed, limited three‑speed adjustment, and the need to replace carbon brushes at regular intervals.

LBSC-400 Fully Automatic Pressurized Core Sampling Machine for Rock Cores Using Liquid Nitrogen

Description

Product Introduction

This machine features a double-column support structure and a fully sealed design, ensuring that the core samples obtained are more complete and accurate while promoting environmentally friendly operation. The drilling speed is regulated by an inverter, overcoming the limitations of the previous DC180 motor—namely, its slow speed, only three adjustable gear settings, and the need to replace carbon brushes at regular intervals. The unit is easy to operate: simply hold down the up or down buttons to initiate automatic vertical movement. It can also be programmed into a PLC for computer‑controlled operation, making it a programmable model (optional). During core extraction, pressing the main unit’s button and selecting the desired speed enables fully automated core retrieval. Furthermore, this machine supports multiple cooling methods: water cooling, liquid nitrogen cooling, and, when dry drilling, an optional dust‑extraction system.

Technical specifications:

Parameter Category	Parameter content
Diamond drill bit	Specifications: φ9–φ100 (standard configuration includes a φ50 mm drill bit); sampling depth ≤400 mm. The diamond is sintered from pure natural diamond, and the drive system employs a splined gear coupled with an electric motor via a flexible coupling.
Lifting motor	Rated voltage: 380 V, frequency: 50 Hz; specifications: 2.5 t; speed ratio: 36:1; main motor power: 2.2 kW.
Lifting mechanism	It employs a 25 mm diameter ball screw with a lifting mechanism, offering an accuracy of 0.01 mm, thereby ensuring core‑drilling perpendicularity and extending the drill bit’s service life.
Control method	Variable-frequency control, with an adjustable range of 0–50 mm.
Spindle speed	1860rpm
Transmission and Machining Processes	The transmission assembly comprises two planetary gear sets and a modular frame, forming a flexible drive system that, when paired with a motor and coupling, achieves mechanical power transmission. The cast‑iron components are manufactured from ductile iron and undergo stress‑relief machining; the main shaft is quenched after machining (hardness HRC), with a surface finish of Ra 0.32.
Lubrication Configuration	Copper bushing with automatic lubrication, featuring inlaid graphite and MoS₂ solid lubricant.
Workbench Structure	Equipped with a worktable that can be moved forward, backward, left, and right, it supports simultaneous multi-point sampling. An optional electronic handwheel enables automatic adjustment of the sampling position, while the worktable offers both horizontal and vertical adjustments.
Dual cooling mode	① Cooling with tap water; ② Liquid nitrogen cooling (suitable for water‑sensitive samples such as mudstone and sandstone; equipped with a 10‑L stainless steel fully automatic pressurized liquid nitrogen tank)
Detection and Protection System	Equipped with an automatic overload protection circuit system.
Fixture type	Supports both manual clamping and pneumatic automatic clamping.
Electrical and Motor Configuration	Electrical components are from the Delixi brand; the motor is a domestically produced, pure copper‑wound unit compliant with national standards, featuring a high‑performance protection rating.
