Abstract
The utility model relates to a hydraulic pressure source of an oil drilling machine, in particular to a cooling device for the hydraulic pressure source of the drilling machine. The technical scheme includes that the cooling device comprises a first oil cooler, a second oil cooler, a water inlet valve, a water drain pipe, an oil inlet pipe and an oil drain pipe, wherein two oil coolers are vertically arranged on a bracket, oil inlets of the first oil cooler and the second oil cooler are parallelly connected to the oil inlet pipe, oil outlets of the first oil cooler and the second oil cooler are parallelly connected to the oil drain pipe, water inlets of the first oil cooler and the second oil cooler are parallelly connected to a water inlet pipeline through the water inlet valve, and water outlets of the first oil cooler and the second oil cooler are parallelly connected to the water drain pipe. According to the cooling device for the hydraulic pressure source of the petroleum drilling machine, the temperature of hydraulic oil is basically equal to that of the cooling water in summer and is guaranteed not to exceed 60 DEG C, oil is changed once a year instead of prior three times a year, simultaneously, the leakage of various positions of the hydraulic pressure source is reduced, and service life and fault-free usage time of various elements are prolonged.
Description
Technical field:
The utility model relates to a kind of oil-well rig hydraulic power, particularly a kind of rig hydraulic power cooling unit.
Background technique:
Hydraulic power is the requisite equipment of drilling crew.Its hydraulic power of present rig for protect with maintenance, repair convenient all be placed on be airtight or semi-closed structure room body in, though ventilating fan and window are arranged, find rig hydraulic power ubiquity smooth, the heat radiation bad phenomenon of ventilating in actual use; The high problem of hydraulic power oil temperature; Especially summer high temperature shows when deep-well makes a trip continuously seriously, and the long-time continuous high load uses; The oil temperature can reach more than 90 ℃, even it is also not obvious to be equipped with the effect of radiation fan.And the normal serviceability temperature of hydraulic oil should be below 60 ℃, and the warm too high meeting of oil causes serious harm, mainly shows the following aspects: 1, hydraulic oil is rotten in advance; The oxidation aggravation; Be prone to form gluey sediments, stop up the aperture in oil purifier and the hydrovalve, make the hydraulic system cisco unity malfunction; 2, hydraulic oil viscosity and hydraulic work system efficient all descend, and leak to increase, and can make the equipment can't proper functioning; 3, the part of hydraulic system expands because of overheated, and matching gap diminishes, and hydrovalve is stuck easily; 4, lubricant film attenuation, mechanical wear increase, and cause precision-fit faces such as pump, valve to make its inefficacy or scrap because of wearing and tearing too early.5, quicken the rubber seal aged deterioration, the lost of life, even lose its sealability, hydraulic system is seriously leaked.Therefore, the warm too high meeting of hydraulic oil oil has a strong impact on the normal use of hydraulic power and liquid gas tong, reduces working life, causes economic loss.
Summary of the invention:
The purpose of the utility model is exactly the above-mentioned defective that exists to existing technology, and a kind of rig hydraulic power cooling unit is provided, and circulates through softened water and takes away the heat of hydraulic oil, strengthens heat radiation, reaches the cooling purpose.
Its technological scheme is: mainly be made up of first oil cooler, second oil cooler, inlet valve, waste pipe, oil inlet pipe, oil exit pipe; Two oil coolers are arranged above and below and are placed on the support; The filler opening of first oil cooler, second oil cooler is parallel to oil inlet pipe, and oil outlet is parallel to oil exit pipe; The water intake of described first oil cooler and second oil cooler is parallel to back with water inlet line through inlet valve; Water outlet is parallel to waste pipe.
The first above-mentioned oil cooler and the bottom of second oil cooler are provided with sewage draining exit.
The beneficial effect of the utility model is: the oily temperature of hydraulic oil in summer is basic and cooling water temperature is fair; Assurance is no more than 60 degree; Drain period can be reduced to annually by original 1 year three times; Reduce hydraulic power leakage everywhere simultaneously, prolonged the working life and the accident-free duration of each components and parts.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: first oil cooler 1, second oil cooler 2, inlet valve 3, waste pipe 4, oil inlet pipe 5, oil exit pipe 6, steam valve 7, sewage draining exit 8.
Embodiment:
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model mainly is made up of first oil cooler 1, second oil cooler 2, inlet valve 3, waste pipe 4, oil inlet pipe 5, oil exit pipe 6, steam valve 7, sewage draining exit 8; Two oil coolers are arranged above and below and are placed on the support; Be relation parallel with one another between two, each is all relatively independent; The filler opening of first oil cooler 1, second oil cooler 2 is parallel to oil inlet pipe 5, and oil outlet is parallel to oil exit pipe 6; The water intake of described first oil cooler 1 and second oil cooler 2 is parallel to back with water inlet line through inlet valve 3; Water outlet is parallel to waste pipe 6; Wherein, the bottom of first oil cooler 1 and second oil cooler 2 is provided with sewage draining exit 8; Steam valve 7 can be when not using, and control dries up internal moisture with pressurized air.
Increase oil cooler, cool off with softened water, this method is that the machine oil cooler of 190 diesel engines that generally use from drilling team is inspired.Its working principle of cooler is identical basically, and just boundary dimension is variant, directly utilizes the oil cooler of 190 diesel engines to be used as the water-filled radiator of hydraulic power.Select the reason of this cooler that the following aspects is arranged: the return pressure of hydraulic power is no more than 2, and the working pressure of oil cooler is normally about 8mPa; Use diesel engine oil cooler convenient sources, installation, maintenance is simple, and 190 diesel engine oil cooler volumes are little in light weight; Pipeline is easy to connect; Oil pipeline and water pipeline be an import and an outlet separately, both can connect with original air-cooler, also can use separately.In the bottom sewage draining exit is arranged, blowdown is convenient.The power of diesel engine is minimum more than 880 kilowatts, be far longer than the power of hydraulic power, and the diesel engine oil temperature can remain on below 70 ℃.Can know that through contrast the machine oil cooler radiating efficiency of 190 diesel engines is high, capacity can satisfy the heat radiation requirement fully, and its internal heat dissipating pipe all uses copper pipe durable in use.Each rig of water softener tank all possesses.Whole transformation process is very simple.40 can use an oil cooler with mo(u)ld bottom half rig suggestion, and 50,70 type rigs can use two oil coolers.This in addition cooler also has the function that a winter hydraulic oil is heated up.Be inserted in the hot water of boiler or high-temperature steam in the threeway of water intake when using hydraulic power in the winter time, can help to improve hydraulic oil oil temperature very soon to more than 0 ℃.
