Description
Technical field
The present invention relates to asynchronous motor, be specially a kind of asynchronous motor for oil field welldrilling.
Background technology
The oil-well rig equipment of China is based on machine driving substantially at present, and domestic only have a spot of import fax to move rig.The critical component of electric drilling machine is the rig asynchronous motor.But existing asynchronous motor is in particular in because the defective of partial structurtes can't fully satisfy the needs in oil drilling field: 1, asynchronous motor for oil field welldrilling often will dispose heater motor internal is implemented directly baking tide.Existing heater is not with explosion prevention function, be that electroheat member (as having heating wire, electric hot plate of fin etc.) is directly fixed on motor internal, even electroheat member itself is that sealing is explosion-proof, but since its wiring particularly binding post expose, so integral body does not have explosion prevention function.There is not the heater of explosion prevention function not satisfy abominable oil drilling operating mode requirement of explosion proof.2, asynchronous motor for oil field welldrilling need adopt the external blower fan to cool off, and the air inlet of blower fan is wanted configuration filter usually, enters blower fan with anti-dust grade.Because the asynchronous motor for oil field welldrilling operating condition is abominable, the sand prevention of motor fan, anti-salt fog etc. there is higher requirement.Fan filter on the existing asynchronous motor is subjected to structural limitations, has been not suitable for abominable operating condition such as land, desert, offshore oil drilling, can not realize functions such as waterproof, sand prevention fully.3, all be fixed with terminal box on the existing motor, be provided with binding post in the terminal box, draw with the motor internal coil with the wiring of other electrical equipment of electric drilling match through binding post.Existing motor adopts threephase cable as lead-out wire usually, but along with the continuing to increase of asynchronous motor for oil field welldrilling power, current of electric constantly increases, and does the requirement that lead-out wire has not reached current density by threephase cable.And heavy current lead-out wire and weak current lead-out wire mix in the existing connection box for motor, and the magnetic field that heavy current and weak current produce interferes with each other.
Summary of the invention
The present invention can't fully satisfy the problem of oil drilling field needs in order to solve the defective of existing asynchronous motor owing to partial structurtes, and a kind of asynchronous motor for oil field welldrilling that improves structure that has is provided.
The present invention adopts following technical scheme to realize: asynchronous motor for oil field welldrilling, comprise the centrifugal fan and the fan filter that are mounted on the support top, and be fixed in the terminal box of support both sides and be fixed in the heater of support bottom; Fan filter comprises a hexahedral framework, be fixed with the mounting panel that has the blower fan connector on it on the end face of framework, at least one end face of all the other end faces of framework is coated with filter course, filter course is by two ends and frame fixation, along the spaced filter grid of end face be covered on the filter grid and constitute with the screen pack of frame fixation all around, each filter grid is made of long filter that interfixes and short filter, the upper end of long and short filter is bent downwardly, and the arrangement position of adjacent filter grid is interlaced.During use,, fan filter is connected with air inlet by the blower fan connector on the mounting panel.Screen pack is to the sand and dust filtration of larger particles, and spaced filter grid is because the position is interlaced, and long and short filter is to filtrations such as thinner sand and dust and water smoke, salt fogs.This fan filter filtration is rationally novel in design, and filter effect is remarkable, is applicable to dust storm, high temperature, high and cold, plateau, humidity, smog, special environment condition such as explosion-proof, is particularly useful for land, desert, offshore oil drilling platform.Terminal box comprises the explosion-proof casing which is provided with the anti-explosion cable joint, at the explosion-proof casing internal fixation three-phase copper bar is arranged, and is fixed with binding post on the copper bar; During use, the three-phase copper bar that motor windings is drawn in the copper busbar of line end and the terminal box is fixed, threephase cable be connected with binding post on the three-phase copper bar and the anti-explosion cable joint from the explosion-proof casing in draw.Heater comprises electric hot plate, also comprise mounting panel, electric hot plate is fixed in a side of mounting panel, the opposite side of mounting panel is fixed with explosion-proof box body, the cable joint that sealing cone rubber plug is arranged in being fixed with on the side end face of explosion-proof box body, the current supply line of electric hot plate pass mounting panel and enter explosion-proof box body and draw from cable joint.By setting up mounting panel and explosion-proof box body, realize explosive-proof sealed in explosion-proof box body of the current supply line of electric hot plate and binding post thereof, thereby make whole heater possess explosion prevention function.This heater has degree of protection height (IP54), characteristics such as explosion-proof.
For further overcoming the problem that strong, weak electricity stream lead-out wire phase mutual magnetic field is interfered, be provided with dividing plate in the explosion-proof casing of terminal box, the three-phase copper bar is positioned at the space of dividing plate one side, and the fixed in space of dividing plate opposite side has main combination junction block and secondary combination junction block.By dividing plate heavy current and weak current are separated, can prevent effectively that the magnetic field that heavy current and weak current produce from interfering with each other.Link to each other with main combination junction block and the secondary junction block that makes up respectively by the electric current power with the lead-in wire of other electrical equipment of electric drilling match (explosion-proof blast switch, auxiliary switch, explosion-proof fan, electric heater, air pressure relay, tightly stop button etc.), like this, by major and minor combination junction block is set the lead-in wire with other electrical equipment of electric drilling match is also separated by the power of electric current.The terminal box of this asynchronous motor adopts the three-phase copper bar to make lead-out wire, can satisfy big electric current and pass through; And the three-phase copper bar is parallel to be installed, and makes things convenient for user installation inlet wire cable; By dividing plate heavy current and weak current are separated, can prevent effectively that the magnetic field that heavy current and weak current produce from interfering with each other; Adopt major-minor combination junction block, with explosion-proof blast switch, auxiliary switch, explosion-proof fan, electric heater, air pressure relay, tightly stop the electric component, control assembly cable of button etc. and electric drilling match by strong and weak electric current wiring.Thereby improve the overall performance of asynchronous motor, make it fully satisfy the needs of oil drilling.
The present invention makes complete machine structure and more perfect function, thereby has satisfied the needs of oil drilling by optimization and improvement to the partial structurtes (comprising heater, terminal box and fan filter) of existing asynchronous motor.Can be used for the abominable oil drilling operating modes of ruuning situation such as land, desert, marine drilling, can satisfy the instructions for use of oil field winch, slush pump, rotating disk even load.This asynchronous motor for oil field welldrilling has effectively been supported the overall strength that China's rig development level, the kind of improving domestic drilling and specification, raising China's oil are equipped, to ensureing the steady production of grand strategy resource oil and natural gas, promote that the China Petroleum sustainable development is significant.
