Have a circular feed inlet, top connection radially offer a feeding pipe, feeding pipe is connected with feed inlet, top connection
Feeding pipe close to lower contact one end is provided with a flow limited nozzle, and lower contact is radially inside opened with top connection coupling part
Equipped with a cavity, a tumbler is installed in the cavity of lower contact, tumbler inner side is radially provided with a core along lower contact
Axis, is provided with a rotor on the lateral wall of mandrel, mandrel is provided with a conical surface block close to flow limited nozzle one end, and conical surface block stretches into institute
State in flow limited nozzle, the first limit shaft and the second limit shaft are installed on the side wall of flow limited nozzle, tumbler passes through the first limit
Position axis and the second limit shaft are fixed in lower contact, and the other end of lower contact radially offers output channel, output channel
The port of export is provided with discharge port.Top connection grafting, which enters, offers external screw thread on the lateral wall of lower contact part, lower contact is with above connecing
Internal thread is offered on the madial wall for the part that head is in contact, top connection is threadedly coupled with lower contact.
In use, user is by fluid by the equipment, and when fluid passes through rotor, rotor rotates, and rotor exists
With limit shaft when mutually moving, rotor is produced relative high frequency and move up and down, the conical surface block at the top of mandrel and flow limited nozzle production
Life does relatively reciprocating motion so that the area of passage of flow limited nozzle produces mechanical periodicity, with no change in pump speed, is pumped small
In the range of produce high frequency change so as to instrument produce dither, this vibration force to reduce frictional resistance, effectively transmit the pressure of the drill, solution
Bit freezing tool etc. has effect well.
The utility model has the advantages and positive effects of：Due to the adoption of the above technical scheme so that the utility model
Operation become more convenient, and equipment designs for all-metal, no rubber, is applicable in the evils such as high temperature, oil-base mud and omits environment, uses
Long lifespan, by varying the diameter of flow limited nozzle, adjusts vibration force, anti-attrition resistance works well, and pressure change is small；And this practicality
It is new that there is simple in structure, easy to maintenance, the advantages that processing cost is low, and production efficiency is high.
