Description
Technical field
The present invention relates to a kind of drilling well, power drill for well workover tool more particularly to a kind of helicoid hydraulic motor damping air deflectors.
Background technology
Oil drilling mainly will be transported to ground than weighted mud or clear water by slush pump or pressure vehicle by rotary hose
Filter enters heavy weight drill pipe using air deflector and finally arrives well inner screw drilling tool, to drive fluid motor rotation to reach drilling well
Purpose.In order to ensure helicoid hydraulic motor rated speed and service life and reduce derrick vibrations, so conveying mud by process
In it should be noted that the following：First, filtering to ensure that no sand grains, sundries enter the stator Intraluminal lesions stator shortening of helicoid hydraulic motor
Drill tool life reduces operation quality, is shaken between helicoid hydraulic motor and derrick second is that practical measures is taken to reduce, except control
It is that helicoid hydraulic motor voltage stabilizing under normal pressure is made to work the purpose of pressure in tubing string, it is necessary to the use of the purpose of damping air deflector be handle
The vibrations of helicoid hydraulic motor normal work and the vibrations of derrick are reduced to minimum limit；Third, from a safety viewpoint considering, accomplish to make
The safe zero defects of industry；And existing helicoid hydraulic motor can not meet above-mentioned requirements simultaneously.
Invention content
The technical problem to be solved by the present invention is to：A kind of helicoid hydraulic motor damping air deflector of good damping effect is provided.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：Helicoid hydraulic motor damping air deflector, including：
Water conservancy diversion central tube and damping tube are provided with connected with outer casing, the water conservancy diversion center on the outside of the water conservancy diversion central tube and damping tube
The upper end of pipe is connected with top connection, and the lower end of the damping tube is connected with lower contact, in the lower end of the water conservancy diversion central tube and subtracts
It is respectively arranged with seal assembly and lock ring between the upper end and connected with outer casing of shake pipe, the water conservancy diversion center in the connected with outer casing upper end
It is provided with fastening nut on pipe, fixing bolt is provided on the fastening nut, in the connected with outer casing and water conservancy diversion central tube
Between be provided with bearing, be provided with locking nut on the damping tube of the connected with outer casing lower end, the connected with outer casing with subtract
It is provided with spring cavity between shake pipe, damping spring, one end of the damping spring and damping tube are provided in the spring cavity
It offsets, the other end and the locking nut of the damping spring offset, outside the connection between the water conservancy diversion central tube and damping tube
Movable cavity is provided in shell.
It is an advantage of the invention that：Above-mentioned helicoid hydraulic motor damping air deflector, can rotate but also damping, by rotation, water conservancy diversion, subtract
Three kinds of functions of shake are combined into together, and multiple functional, good damping effect, safety and environmental protection reduces labor intensity, substantially increases work
Efficiency.

Specific implementation mode
The particular content of the present invention is described in detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, helicoid hydraulic motor damping air deflector, including：Water conservancy diversion central tube 1 and damping tube 2, at the water conservancy diversion center
The outside of pipe 1 and damping tube 2 is provided with connected with outer casing 3, and the upper end of the water conservancy diversion central tube 1 is connected with top connection 4, the damping
The lower end of pipe 2 is connected with lower contact 5, between the lower end of the water conservancy diversion central tube 1 and the upper end and connected with outer casing 3 of damping tube 2
It is respectively arranged with seal assembly 6 and lock ring 7, fastening nut 8 is provided on the water conservancy diversion central tube 1 of 3 upper end of the connected with outer casing,
It is provided with fixing bolt 9 on the fastening nut 8, bearing is provided between the connected with outer casing 3 and water conservancy diversion central tube 1
10, be provided with locking nut 11 on the damping tube 2 of 3 lower end of the connected with outer casing, the connected with outer casing 3 and damping tube 2 it
Between be provided with spring cavity 12, damping spring 13, one end of the damping spring 13 and damping are provided in the spring cavity 12
Pipe 2 offsets, and the other end and the locking nut 11 of the damping spring 13 offset, between the water conservancy diversion central tube 1 and damping tube 2
Connected with outer casing 3 in be provided with movable cavity 14.
Operation principle：Helicoid hydraulic motor damping air deflector is that one of helicoid hydraulic motor attachment its major function is water conservancy diversion and damping
Function, the mainly convenient assembly and disassembly maintenance single in operation of rotation, avoids influencing entirely because smallclothes block
Drilling tool operation, while shaking rotation also there is damping efficacy, fixing bolt 9 can also be locked when normal work and not rotated.
Above-mentioned helicoid hydraulic motor damping air deflector in use, filter is accepted on helicoid hydraulic motor damping air deflector top, hold by lower part
Heavy weight drill pipe is connect, guide functions are played in centre.Mud is pressed into after filter by slush pump or pressure vehicle enters water conservancy diversion from top connection 4
Inside central tube 1, water conservancy diversion center, be sequentially arranged with from bottom to top between 1 and connected with outer casing 3 lock ring 7, seal assembly 6, bearing 10,
Fastening nut 8, fixing bolt 9 (can be fixed and not rotated with four-point), 3 shell of connected with outer casing is flowed into from 1 inside of water conservancy diversion central tube
Movable cavity 14 in push damping tube 2 to move downward and (have the function of bumper and absorbing shock), determined by the size of fluid pressure
It is fixed, while compression shock absorption spring 13, at this point, 11 stress of locking nut becomes larger, liquid is exited into down from 2 centre bore of damping tube and is connect
First 5.Most enter drive rotor movement in helicoid hydraulic motor through heavy weight drill pipe afterwards and drive drill bit drilling well, since drill bit produces in drilling process
Raw vibrations pass through helicoid hydraulic motor to upload, at this position because being equipped with damping spring 13, up and down fortune of the damping tube 2 in damping spring 13
Cushioning effect is played under dynamic.
