Abstract
The utility model relates to an automatic pressure fan for a petroleum drilling machine. The utility model is composed of a control system, a transmission shaft assembly, a gas storage tank / oil-gas separator, an oil cooler, an air cooler, a water-gas separator, etc. Clean and dry compressed air can be obtained adopting the utility model which reduces the maintenance of gas equipment used for the drilling machine, and the service life of a screw type compressor is long. The utility model has the advantages of few wearing parts and low maintenance cost. The utility model which adopts gas pressure control is advantageous to fire prevention.
Description
The utility model relates to the automatic pressure fan of a kind of oil-well rig.
The compressor of the automatic pressure fan that present domestic petroleum rig is equipped with more than 90% all is to be piston compressor.Piston compressor exists many technical problems, and operating life is subjected to all multifactor influences such as valve block, piston ring, lubrication circumstances, is not very long, and what have has only more than a year.Shut down maintenance because the fault of compressor usually causes, influenced normally carrying out of drilling well work.
State's inner compressor industry has also been carried out extensive studies and exploitation to the automatic control of compressor, as 88217090.2 of CN20413724 bulletin announcement, a kind of exactly fully automatic piston type compressor that utilizes little electric control.If this technology is applied on the oil-well rig, still exist not high shortcoming of piston compressor life-span.
The purpose of this utility model is to provide a kind of long working life, the automatic compressor of the screw type that utilizes air pressure to control.
Automatic pressure fan of the present utility model is introduced automatic pressure fan by V belt with power by the clutch end of oil-well rig diesel engine unit.According to the height of oil-well rig main line air pressure, start automatically or close compressor, provide pressurized air to main line, make it maintain a pressure stable scope, guarantee the proper functioning of each pneumatic equipment of oil-well rig.Accompanying drawings is as follows:
Fig. 1 is a plan view of the present utility model.
Fig. 2 is a left view of the present utility model.
Fig. 3 is a flow chart of the present utility model.
Among Fig. 1, the anterior fixed conveyor axle assembly of base 1.Driving-shaft assembly 2 is by the bearing support 3 that is fixed on the base 1, be installed in the pair of bearings 4 of bearing support 3 inner chambers, be installed in the bearing cap 5 that compresses bearing 4 on the bearing support 3 by bolt, pass bearing 4 and bearing cap 5 endoporus and be installed in transmission shaft 6 on the bearing 4, be installed in the unidirectional rotation air guide joint 7 of transmission shaft 6 front ends, be installed in the belt pulley 37 of transmission shaft front portion and the air clutch 8 at rear portion, transmission shaft 6 cores are shaped on the gas circuit of passing through for air 12, connecting the gas circuit 12 of transmission shaft 6 and the conduit 9 of air clutch 8 constitutes.What fix on the base 1 of driving-shaft assembly back is screw compressor 11.Air clutch 8 on the transmission shaft 6 is containing friction wheel 10, friction wheel 10 is installed in the preceding shaft extension part of screw compressor 11, hang 10 rotations of fashionable air clutch drive friction wheel, screw compressor 11 work, the back shaft extension of screw compressor has partly been installed the fan 35 of cold oil cooler 13 gentle coolers 14.What fix on the base 1 of screw compressor 11 back is that oil cooler 13 gentle coolers 14 are forced cooling by 35 pairs of coolers 13 of fan and 14.What fix on the base 1 of gas cooler 14 back is gas holder/deaerator 15.Like this, on base 1, fixing driving-shaft assembly 2, screw compressor 11, oil cooler 13, gas cooler 14 and gas holder/deaerator 15 from front to back successively.
Unidirectional rotation air guide joint 7 is installed in the end of transmission shaft 6, rapid escape valve 20 links to each other with unidirectional rotation air guide joint 7 usefulness pipelines, dual-purpose air feeding apparatus 19 usefulness pipelines link to each other with rapid escape valve 20, link to each other with sequence valve 18 again, sequence valve 18 usefulness pipelines 17 link to each other with main gas circuit 34, constitute control system.
Among Fig. 2, on the base 1 in screw compressor 11 left sides, fixing moisture separator 16.Its back is installed with oil cooler 13, gentle cooler 14.
Among Fig. 3, by the sequence valve 18 that links to each other with main gas circuit pipeline 34 with pipeline 17, the dual-purpose air feeding apparatus 19 that links to each other with sequence valve 18 and main gas circuit pipeline 34 with pipeline, the rapid escape valve 20 that links to each other with dual-purpose air feeding apparatus 19 with pipeline, link to each other with rapid escape valve 20 and be installed in the control system of unidirectional rotation air guide joint 7 formations on the transmission shaft 6 with pipeline.When the pressure of main gas circuit is lower than setting value, sequence valve 18 actions, to carry out signal and issue dual-purpose air feeding apparatus 19, dual-purpose air feeding apparatus 19 with main gas circuit 34 to air clutch 8 air feed, air clutch 8 is hung with friction wheel 10 and is closed, all the time the transmission shaft 6 that is in rotation status by belt transmission drives screw compressor 11 work, air feed in main gas circuit.When the pressure of main gas circuit 34 reaches setting value, sequence valve 18 actions, to carry out signal cancels, dual-purpose air feeding apparatus 19 has cut off the gas path of main gas circuit 34 and rapid escape valve 20 and unidirectional rotation air guide joint 7, the air of pressure that has in the air clutch 8 is discarded to atmosphere from rapid escape valve 20, air clutch 8 breaks away from friction wheel 10, and screw compressor 11 quits work.
Adopt the automatic pressure fan of screw type of the present utility model, reduced the maintenance of rig gas equipment, more piston type compressed captain of the life-span of screw compressor, and few easy workout part, maintenance cost reduce, adopt air pressure control to help the rig fire prevention, in a word, good economic benefits is arranged.
