Due to the needs of fracturing work, often because the reason of high pressure makes the plug of fluid end skid off displacement, cause of the fracturing fluid leakage, and make fracturing pump head pressure unstable, produce larger fluctuation.If termination of pumping not in time, and the problem of plug displacement is processed, cause plug to collapse, the normal operation of whole fracturing work and the damage of equipment will be affected.So in fracturing pump running, fluid end plug skids off the major issue that displacement will be a safety in production.
The detecting method that plug of the prior art skids off displacement makes a mark for crossing with marking pen on plug and fluid cylinder.The marking pen mark vestige that operating personnel is observed in operation process by monitoring unit judges whether plug has the phenomenon skidding off displacement.This method needs operating personnel's Real Time Observation fracturing pump working condition, easily causes operating personnel tired, the displacement situation of plug can not be detected timely and effectively.Therefore research and develop a kind of detection technique skidding off displacement for fracturing pump plug and will become further important and urgent.
Model utility content
The purpose of this utility model is the shortcoming overcoming prior art, provides that a kind of structure is simple, easy-to-operat, the fracturing pump plug shift detector based on infrared senor that can accurately detect.
The purpose of this utility model is achieved through the following technical solutions: a kind of fracturing pump plug shift detector based on infrared senor, comprise fluid cylinder, plug, sender unit, signal receiving device and control system, described plug is arranged on fluid cylinder, described fluid cylinder is provided with sender unit and signal receiving device, the both sides that described sender unit and signal receiving device are positioned at plug are oppositely arranged; Described sender unit is all connected with control system with signal receiving device, when plug skew exceed normalized distance from, described signal receiving device receives the signal that sender unit sends, and control system performs the action stopping fracturing pump running after receiving the signal of signal receiving device.
Further, described sender unit is infrared sensing transmitter, and signal receiving device is infrared sensing receiver.
Further, it also comprises block piece, and described block piece is arranged on plug; When plug skew do not exceed normalized distance from time, described block piece blocks between sender unit and signal receiving device, and now, signal receiving device cannot receive the signal that sender unit sends.
Further, described block piece, sender unit and signal receiving device are positioned on same axis, and described block piece is positioned at sender unit and signal receiving device middle between the two.
Further, it also comprises mounting bracket, and described mounting bracket is arranged on fluid cylinder, and described sender unit and signal receiving device are fixedly mounted on mounting bracket.
Further, also comprise fixed support, described fixed support is arranged on plug, and described block piece is fixedly mounted on fixed support.
Further, described block piece is rectangular thin-slab structure.
The utility model has the following advantages: relative in the both sides of plug is provided with infrared sensing transmitter and infrared sensing receiver, and be provided with block piece between, thus achieve under normal circumstances, infrared sensing receiver cannot receive the signal that infrared sensing transmitter sends, and when plug skew exceed normalized distance from, described infrared sensing receiver receives the signal that infrared sensing transmitter sends.There is structure simple, easy-to-operat and detect accurately, can be out of service in time when exception, improve the Security in fracturing pump running greatly.
Accompanying drawing explanation

Fig. 2 is package assembly schematic diagram of the present utility model;
In figure: 1-fluid cylinder, 2-plug, 3-mounting bracket, 4-sender unit, 5-control system, 6-block piece, 7-fixed support, 8-signal receiving device.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1 and Figure 2, a kind of fracturing pump plug shift detector based on infrared senor, comprise fluid cylinder 1, plug 2, sender unit 4 and signal receiving device 8, described plug 2 is arranged on fluid cylinder 1, described fluid cylinder 1 is provided with sender unit 4 and signal receiving device 8, the both sides that described sender unit 4 and signal receiving device 8 are positioned at plug 2 are oppositely arranged; When plug 2 skew exceed normalized distance from, described signal receiving device 8 receives the signal that sender unit 4 sends.Adopt such structure move for detecting fluid cylinder 1 upper plug head or skid off distance, structure is simply easy to operation, and can be mounted on easily on fluid cylinder 1.
Described sender unit 4 is infrared sensing transmitter, and signal receiving device 8 is infrared sensing receiver.
It also comprises block piece 6, and described block piece 6 is arranged on plug 2; When plug 2 offset do not exceed normalized distance from time, described block piece 6 blocks between sender unit 4 and signal receiving device 8, and now, signal receiving device 8 cannot receive the signal that sender unit 4 sends.Signal cannot be received by arranging block piece 6 in order to realize signal receiving device 8 under normal circumstances, and when plug 2 skew exceedes normal value, signal receiving device 8 must receive signal.Therefore block piece 6 needs to be arranged on plug 2, and the shape and structure of block piece 6 and with the position relationship of sender unit 4, signal receiving device 8 can be suitable as required change, as long as can above-mentioned functions be realized.
Preferably, described block piece 6, sender unit 4 and signal receiving device 8 are positioned on same axis, and described block piece 6 is positioned at sender unit 4 and signal receiving device 8 middle between the two.
It also comprises mounting bracket 3, and described mounting bracket 3 is arranged on fluid cylinder 1, and described sender unit 4 is fixedly mounted on mounting bracket 3 with signal receiving device 8.Adopt mounting bracket 3 for fixed installation, sender unit 4 and signal receiving device 8 can be made to install more stable.
It also comprises fixed support 7, and described fixed support 7 is arranged on plug 2, and described block piece 6 is fixedly mounted on fixed support 7.Use fixed support 7 to fixedly mount block piece 6, can ensure that block piece 6 does not rock or moves in running, guarantee the accuracy detected.
Preferably, described block piece 6 is rectangular thin-slab structure.
Working procedure of the present utility model is as follows: under normal circumstances, sender unit 4 sends infrared signal to signal receiving device 8, owing to there being block piece 6 to stop between sender unit 4 and signal receiving device 8, signal receiving device 8 can not receive the infrared signal from sender unit 4.In fracturing work process, skid off displacement when plug 2 causes because of high pressure, plug 2 is offset, and block piece 6 offsets thereupon.When inclined overrun, the signal receiving device 8 of infrared senor will receive the infrared rays from sender unit 4, and is converted to electrical signal, is sent in PLC control system 5 by signal cable 5.When PLC detects that sensor signal triggers, fracturing pump manufacture will be run by program or to send alarm operating personnel out of service and carry out repair and maintenance to this fracturing pump, ensure that the safety of fracturing work is carried out.
