Embodiment 1

[0028] Example 1, such as figure 2 As shown, the detection device 4 is a pair of infrared sensors arranged oppositely, one of which is an infrared sensor transmitter, and the other is an infrared sensor receiver, and the infrared sensor transmitter and infrared sensor receiver Located on opposite sides of the plug 2; when the offset of the plug 2 does not exceed the normal distance, the blocking member 6 is blocked between the infrared sensor transmitter and the infrared sensor receiver. At this time, the infrared sensor receives The device cannot receive the signal sent by the infrared sensor transmitter; when the plug 2 deviates beyond the normal distance, the infrared sensor receiver receives the signal sent by the infrared sensor transmitter, and the control system 5 receives the signal received by the infrared sensor The action of stopping the operation of the fracturing pump is performed after the signal of the fracturing device.

[0029] Preferably, the shielding memb...

Embodiment 2

[0030] Embodiment 2, the detection device 4 is a position detection device, the position detection device is located above or below the plug 2, the position detection device is set opposite to the shutter 6, and the position detection device detects the shutter 6 in real time and sends a signal to Control system 5; when the plug 2 moves beyond the normal range, the position detection device cannot detect the blocking member 6, the signal transmission is terminated, and the control system 5 executes the action of stopping operation or sends out an alarm signal.

[0031] A detection method for a plug displacement detection device of a fracturing pump is adopted, which comprises the following steps:

[0032] S1: install the plug 2 and the detection device 4, and connect the detection device 4 with the control system 5; install the blocking member 6;

[0033] S2: When the offset of the plug 2 does not exceed the normal distance, the control system 5 does not take any abnormal acti...

The invention has the advantages of simple and convenient operation, accurate detection results, timely and effective maintenance, and greatly improves the safety during the operation of the fracturing pump.

Description

technical field [0001] The invention relates to a fracturing pump, in particular to a fracturing pump plug displacement detection device and a detection method thereof. Background technique [0002] With changes in the global energy supply structure, unconventional energy sources such as shale gas and tight oil are gradually playing an increasingly important role. However, with the development of unconventional energy sources, such as horizontal well technology, the pumping environment of fracturing fluid has become more severe, and fracturing operations need to use higher pressure and longer operating time, which will aggravate the high pressure pumping system. Component damage, especially the fatigue failure and wear of the liquid end under the action of periodic high pressure. [0003] Due to the needs of fracturing operations, the plug at the hydraulic end often slips out and shifts due to high pressure, resulting in leakage of fracturing fluid, and unstable discharge p...
