Fig. 6 is a kind of structural schematic diagram of pumping unit blowout hookup provided by Embodiment 2 of the present invention, as shown in fig. 6, this
The pumping unit blowout hookup of embodiment includes: shell 1, and shell 1 is internally provided with cavity 11, is additionally provided on shell 1 through chamber
The channel 12 of body 11, channel 12 is for accommodating sucker rod (being not shown in Fig. 2).It is provided in cavity 11 for being set in oil pumping
Flexible seals 2, detection unit 5, gas source 4 and the control unit 3 of bar outer wall, flexible seals 2 are fixedly connected with shell 1, inspection
It surveys unit 5 to be arranged on the outer surface of flexible seals 2, detection unit 5 is connect with control unit 3, control unit 3 and gas source 4
Connection.Pressure gauge 6 is arranged outside shell 1, and with 11 connection of cavity, pressure gauge connect with monitoring device 7.
Whether deformation occurs for detecting flexible seals 2 for detection unit 5, when deformation occurs for flexible seals 2, to control
Unit 3 processed sends control signal, and control unit 3 is used to generate gas according to control signal control gas source 4 to squeeze flexible sealing
Part 2.Pressure gauge 6, the pressure for measuring in cavity 11, and the pressure measured in obtained cavity 11 is sent to the prison
Equipment 7 is controlled, monitoring device 7 is used for when the pressure in cavity 11 is greater than preset first pressure, and control pumping unit stops working.
Pumping unit blowout hookup provided in this embodiment increases pressure gauge 6 and monitoring device compared with Fig. 1 shown device
7, so as to pass through the pressure in the real-time test chamber 11 of pressure gauge.As shown in fig. 6, offering pressure tap on shell 1
15, pressure tap 15 is connected to cavity 11, and the measurement end of pressure gauge 6 is directly connect with pressure tap 15, alternatively, the measurement of pressure gauge 6

The present invention also provides a kind of pumping unit, which includes pumping unit ontology and above-mentioned Fig. 1, oil pumping shown in fig. 6
Machine blowout hookup.Pumping unit is a kind of machinery equipment for exploiting petroleum, is commonly called as " kowtowing machine ".Pumping unit is in rod pumping system
Main lifting equipment mainly pumps oil by the swabbing action of a sucker rod, is then sent by the pipeline that underground is buried
It walks, sucker rod is motor-driven by one.
Pumping unit can be divided into beam pumping unit and without beam pumping unit according to whether there is walking beam.
The working principle of beam pumping unit is: being supplied power by engine, through retarder by the high-speed rotation of engine
Become slowly running for oil pumping machine crank, and rotary motion is become into pumping unit horsehead from crank-connecting rod-walking beam mechanism
It is upper and lower to move back and forth, deep-well pump work is driven through polished rod eye assembly.
The main component of beam pumping unit has: the engine of power is provided, power is transmitted and reduces the retarder of speed,
Rotary motion is simultaneously become the four-bar mechanism (crank, connecting rod, walking beam, bracket and crossbeam and pedestal) moved back and forth by transmitting power,
Transmitting power simultaneously guarantees that polished rod does the horse head and polished rod eye assembly of linear reciprocating motion, and oil pumping function is made to rest on any position
Brake gear and to make power function balancing device etc. for working in a lesser load variation range.
For the movenent performance for improving pumping unit, energy-saving effect is improved, main screw lift and occupied area are reduced, in recent years in oil field
Field application mainly has chain drive pumping unit and steel rope oil sucking machine without beam pumping unit.
When in use, pumping unit blowout hookup is fixed on to the well head of pumping unit, the sucker rod of pumping unit passes through pumping unit
It is protruded into pumpingh well behind the channel of blowout hookup, pumping unit ontology is rest on the ground.
