Description
Technical field
It is used double the invention belongs to oil exploration, oil exploitation, oil refining, oil product transportation art industry
The horizontal sand pump of end surface mechanical sealing, especially oil drilling explore industry, and Solids control for drilling fluids equipment is with double mechanical
The horizontal sand pump of sealing.
Background technology
Industry is explored in oil drilling at present, the blood that drilling fluid is drilled as drilling machine can lubricate the drill bit of underground, will
Rock debris return is taken on ground, after being filtered separation, then is pressed into underground recycling, drilling fluid is a kind of viscosity
Greatly, proportion is high, the mixed type liquid more than granule content, also referred to as mud, and the pump for conveying drilling fluid is referred to as sand pump, at present sand pump
All it is the single mechanical end face seal structure used, under severe working condition, mechanical seal service life shortens dramatically in pump,
And once meeting with fluctuation of operating conditions and the variation of burst, then single mechanical end face seal damages immediately, ultimately causes sand pump leakage.It is single-ended
Specific defect existing for face mechanical seal is as follows：
1, when the medium of conveying is when freezing in cold winter, the frozen medium of single mechanical end face seal is surrounded
With freeze, when starting sand pump, the frozen medium of mechanical seal is fettered, and medium of the single mechanical end face seal without liquid lubricates
Cooling, mechanical seal end surface drastically dry friction, mechanical seal damages rapidly leakage.
2, when the medium of conveying occurs dry and hard during the broiling summer, single mechanical end face seal is surrounded by dry and hard medium
With it is dry live, when starting sand pump, mechanical seal is fettered by dry and hard medium, and medium lubrication of the single mechanical end face seal without liquid is cold
But, mechanical seal end surface drastically dry friction, mechanical seal damage rapidly leakage
No matter 3, which kind of reason, when pump intake without medium into fashionable, i.e. pump is in evacuating without medium operating condition, single end face
Mechanical seal is without medium lubrication, and drastically dry wear, mechanical seal damage rapidly leakage to mechanical seal end surface.
4, when conveying hyperbaric drilling fluid, drilling fluid can be stopped and is bonded at mechanical seal end surface, cause machinery
The heat of sealing does not distribute not go out, and mechanical seal is caused to leak.
Single mechanical end face seal failure caused by above-mentioned reason accounts for 50% or more horizontal sand pump total failare rate.Maintenance maintenance takes
With total 70% or more the maintenance and repair expense of horizontal sand pump is accounted for, the Double End machine of good running environment is capable of providing because the invention is a kind of
The horizontal sand pump of tool sealing structure is very necessary, by the lubrication structure of some auxiliary, ensures that horizontal sand pump is stablized
Long-acting operation.
Invention content
The object of the present invention is to provide a kind of horizontal sand pumps with double-face mechanical sealing structure, overcome above-mentioned single end face
The various defects and disadvantage that mechanical seal occurs in use improve the operation stability of complete machine pump, enhance to harsh work
The adaptability of condition condition, prolongs the service life, and meets requirement.
In order to achieve the above objectives, a kind of horizontal sand pump with double-face mechanical sealing structure is provided, it is characterised in that：Packet
Include double-face mechanical sealing structure, sealing box assembly, pumping nested structure and cooling tank assembly.
The double-face mechanical sealing structure, it is characterised in that：Double-face mechanical sealing structure includes double mechanical
Sealing and axle sleeve.
The sealing box assembly, it is characterised in that：It includes seal box and pump cover to seal box assembly.
The pumping nested structure, it is characterised in that：It includes pumping set and double mechanical seal to pump nested structure.
The cooling tank assembly, it is characterised in that：Cooling tank assembly includes cooling tank, liquid level gauge, inlet tube, goes out liquid
Pipe.
Double-face mechanical sealing structure is located among sealing box assembly, the full machine oil of filling in sealing box assembly, pumping set position
In the outside of double-face mechanical sealing structure, sealing box assembly connects cooling tank by outlet tube with inlet tube.
Double-face mechanical sealing structure will produce friction and stirring heat when rotated, cause the machine oil in sealing box assembly
Temperature rise.When double mechanical seal rotates, surrounding machine oil is driven to rotate, so that the machine in sealing box assembly
Oil is moved along the helicla flute on pumping nested structure to side, is entered inside cooling tank assembly by outlet tube, cooling tank is total
It is to carry heat radiating fin structure at outside, can be cooled down by the cold wind air-flow of electrical motor fan, machine oil passes through cooling tank
It after the cooling heat dissipation of assembly, by inlet tube back to sealing inside box assembly, so moves in circles, quilt in box assembly will be sealed
The constantly cooled tank assembly cooling of the machine oil heat of heating, keeps the oil temperature in sealing box assembly to be in low temperature always
State, running environment for double-face mechanical sealing structure and its advantageous.
Advantageous effect：It is an object of the present invention to overcome the horizontal sand pump of the field single mechanical end face seal structure without
The structural measure of any guarantee so that single mechanical end face seal damages again and again in use, double-face mechanical sealing structure
Application, improve horizontal sand pump reliability, the service life for extending horizontal sand pump, adapt to the variation of various working condition, thoroughly solve
Existing defect during the horizontal sand pump use of single mechanical end face seal in the certainly described field.
The advantage of horizontal sand pump with double-face mechanical sealing structure is through double mechanical seal and correlation
The structure of connection provides a superior running environment for double-face mechanical sealing structure, and lasting lubrication remains operational
Environmental stability, to improve the reliability of Horizontal sand pump operation.
