The mud pump flushing speed is a drilling parameter to be measured during oil drilling or workover operations. The mud pump flushing speed sensor adopts a non-contact measuring mode and consists of a proximity sensor, a junction box and other parts. The working principle of the mud pump flushing speed sensor is as follows: the metal object passes through the proximity sensor near the sensing surface to generate a pulse signal, the pulse signal is sent to the acquisition and processing unit through a cable, and the current pump stroke speed is calculated and displayed after processing. The induction end face of the inductive proximity sensor on the mud pump flushing speed sensor has strict induction distance requirements with the end face of an object to be induced, but when the mud pump flushing speed sensor is installed on the cross head cover plate, the distance between the induction end face of the sensor and the end face of the object to be induced cannot be measured through various rulers, the distance is not appropriate, signals of reciprocating motion of a cross head bolt cannot be induced, or the signals are weak, even the proximity sensor can be damaged, measuring and displaying of the flushing speed parameters of the mud pump are influenced, and therefore inconvenience is brought to well drilling and repairing operation. Therefore, it is necessary to design a mud pump impact sensor that can precisely adjust the sensing distance between the sensing end face of the proximity sensor and the end face of the crosshead bolt head.
Disclosure of Invention
The utility model discloses an overcome the mud pump towards fast sensor of background art and have inductive proximity sensor's response terminal surface and by the unable accurate determination of response distance between the response thing terminal surface to cause the signal that the response can not arrive cross head bolt reciprocating motion or the signal is weak, can also bump bad proximity sensor even, show for mud pump towards fast parameter measurement and cause the influence, thereby bring inconvenient problem for the operation of drilling and repairing the well, and provide a can adjust the mud pump towards fast sensor of response distance, the utility model discloses a mud pump towards fast sensor can accurate adjustment sensor response terminal surface and cross head bolt head terminal surface between response interval, with installation and the use problem of solving mud pump towards fast sensor.
The utility model adopts the technical proposal that:
the utility model provides a can adjust inductive distance's mud pump rush sensor, includes explosion-proof terminal box assembly, lock nut, screw rod, swivel nut, mounting nut, probe shell, sensor, and the sensor is installed in the probe shell, and the cable of sensor links to each other its characterized in that with the binding post of explosion-proof terminal box assembly: one end of the screw is screwed into the explosion-proof junction box assembly and fixed by a first locking nut, and two mounting nuts are screwed into the threaded sleeve; a second locking nut, a threaded sleeve and a third locking nut are screwed in the screw rod in sequence; and a probe shell provided with a sensor is screwed in and installed at the other end of the screw rod, the probe shell is locked by a third locking nut, and a cable of the sensor passes through a central hole of the screw rod and is connected to a wiring terminal of the explosion-proof junction box assembly.
When the sensor is assembled, the left end of the screw is screwed into the explosion-proof junction box assembly, and when the screw is adjusted to a proper screwing depth, the screw is locked by using a first locking nut; a second locking nut and a threaded sleeve are screwed in the screw rod in sequence, and a second mounting nut is screwed in the threaded sleeve; and then a third locking nut is screwed into a proper position on the screw rod, the sensor is firstly installed and screwed into the probe shell, a cable carried by the sensor passes through a central hole of the screw rod and is connected to a wiring terminal in the explosion junction box assembly, and the left end of the probe shell provided with the sensor is screwed into the right end head of the screw rod.
The screw rod rotates for one circle, and the axial moving distance is one thread pitch, so that the induction distance between the sensor and the end face of the crosshead bolt head can be accurately adjusted. The utility model discloses mud pump rush sensor principle lies in: through except that swivel nut and mounting nut all the other parts along with the screw rod forward rotation in the swivel nut contacts crosshead bolt head terminal surface gently to the response face of sensor, then reverse rotation toward returning back again, rotatory toward returning back the round, axial displacement distance is a pitch, through predetermineeing the number of rotations, just so can the accurate response interval between adjustment sensor and the crosshead bolt head terminal surface.
The utility model discloses simple structure is reliable, and simple to operate can solve mud pump fast sensor installation and service problem really.
