Technical field
A kind of laboratory oil inlet metal tubes cleaning device is the utility model is related to, for cleaning experiment room because oil inlet is dirty
The metal tubes of dye, prevent the hydraulic oil pollution pipeline into pipeline from influencing experiment.
Background technology
Common experimental facilities is exactly three axis seepage tests machines in coal containing methane gas mechanics, rock mechanics laboratory, and three axis ooze
Stream mechanics machine is mainly used for the research of stand under load rock seepage characteristic and aqueous gassiness mechanical property of coal seam changing rule.
No matter percolating medium is gas or water, it is required to give certain pressure, an end face of coal petrography sample is passed to, by another
End face is oozed out, and to ensure that coal sample avoids completely cutting off with triaxial cell during seepage flow, the water that makes to pass through in coal sample, gas not into
Enter triaxial cell, while the hydraulic oil in triaxial cell is not entered in coal sample, prevent hydraulic oil pollution coal sample, pollute
Pipeline.Coal sample seals mainly constrains the rubber sleeve for being close to coal petrography wall to complete, but in hyperbar, Gao Shui using ferrule
During pressure, misoperation, coal petrography bursting stress are fallen etc., the sealing of coal petrography sample is easy to be broken, in triaxial cell
Hydraulic oil pour in coal petrography sample, from water, gas inlet and outlet feed line, pollute pipeline, or even can be trapped in pipeline, under the influence of
Secondary experiment, or damage equipment.
The water of three axis permeation fluid mechanics testing machines, air infiltration flow tube road, are pressure-bearing metal pipe, and in order to which laboratory experiment needs
Will, meander-shaped is bent into using pipe bender more, and there are pipeline aperture to differ, the situation that aperture is mutated, traditional pipeline
Method for cleaning has gas purging, but also there are certain deficiency for gas purging method.
（1）Gas scavenging pipeline, though congestion thing that can to a certain extent in scavenging pipeline, for caliber mutation,
The longer pipeline of pipeline, the pressure loss are larger, it is impossible to abundant cleaning channels.
（2）Gas purging is only capable of utilizing gas flow at high rates, carries the running of hydraulic power oil being detained on pipeline, handles in pipeline
Greasy dirt, it is limited for the greasy dirt cleaning ability on adhesion pipeline wall.
Therefore the utility model provides a kind of laboratory oil inlet metal tubes cleaning device, can efficiently use acetone stream
Dynamic carrying capacity, the principle that mixes similar to hydraulic oil to acetone, cleaning experiment room oil inlet metal tubes, prevention are polluted by the oil pipe
Road influences experiment, damages metering device.
Utility model content
The utility model adopts the following technical solution：Design a kind of laboratory oil inlet metal tubes cleaning device, the device
Mainly include nitrogen cylinder, Miniature diaphragm pump, acetone tank, cucurbit, constant water bath box, condenser, Miniature diaphragm pump can be by third
Acetone in ketone tank is pumped into pipeline, it is connected to a connector of the first threeway by pressure-bearing pipe, valve, and nitrogen cylinder can provide
High pressure nitrogen, for residual acetone in scavenging pipeline, it is connected to another of the first threeway by pressure-bearing pipe, pressure reducing valve, valve
Connector, the 3rd connector of the first threeway are connected to the entrance of oil inlet metal tubes, oil inlet metal tubes by pressure-bearing pipe, valve
Outlet a connector of the second threeway is connected to by pressure-bearing pipe, another connector and the cucurbit entrance of the second threeway connect
Connect, the 3rd connector of the second threeway connects blow-down pipe through valve, and cucurbit outlet is connected to condenser inlet, and condensator outlet passes through
Pressure-bearing pipe is connected to acetone tank, and cucurbit can realize the Collection utilization of acetone with condenser, and greasy dirt is collected in cucurbit.
