Problems solved by technology
[0004] Although the manufacturer’s previous scheme of using prostheses and laser point positioning can be applied, it is difficult to provide reliable and quantitative basis for size review. It is necessary to frequently lift the pump body away and measure the deviation value of the laser point to determine the installation error. It is time-consuming and labor-intensive to set up the operation platform and measure personnel to measure repeatedly, and the installation cycle of each unit is very long

Embodiment
[0021] The test and installation method of the deep well pump in this embodiment, the deep well pump includes a pump body 11 and an intermediate support 12 arranged on the pump body 11; figure 1 and 2 As shown, the test installation method of this embodiment includes the following steps:
[0022] Step 1: Preliminarily determine the upper and lower heights of the pump body 11 and the installation position of each intermediate support 12, and use the theodolite to observe the accuracy of the position;
[0023] Step 2: According to the requirement that the center of the pump body 11 must be parallel to the longitudinal bulkhead 2 and the transverse bulkhead 3 of the cabin, hoist the pump body 11 and temporarily align it, and adjust the up and down, left and right, and front and rear distances of the pump body 11 through the tensioner ;
[0024] Step 3: Select a digital display grating ruler 4 with an accuracy ≥ 0.01 mm, and fix the digital display grating ruler 4 at the bottom,...

The invention relates to a test mounting method of a deep-well pump. The test mounting method comprises the following steps that firstly, the pump body mounting position is initially decided; secondly, a pump body is lifted and temporarily aligned; thirdly, digital display grating rulers with the precision larger than or equal to 0.01 mm are selected, the digital display grating rulers are fixed to the bottommost part and the middle of the deep-well pump and the longitudinal and transverse cabin walls of a cabin deck portion, and are used for measuring relative sizes of the pump body shell onthe horizontal plane, that is the coordinates of a certain reference point of a pump shell; fourthly, through the mounting method in the third step, the vertical digital display grating ruler is mounted on the bottom of the cabin, and the pump body vertical displacement is recorded; fifthly, the pump body is moved away, before a solid support is mounted, numerical values of all points are recorded, and measuring rod heads of the digital display grating rulers shrink to the proper position; and sixthly, a supporting frame is welded, the pump body is re-assembled, the measuring rod heads of thedigital display grating rulers extend out, and the instant numerical value and the memory numerical value are compared. The method has the advantage that the mounting period can be shortened, the mounting error is reduced, and the mounting reliability is ensured.
Description
technical field [0001] The invention relates to the installation of deep well pumps, in particular to a method for testing and installing deep well pumps. Background technique [0002] As an oil product shipping equipment, the deep well pump is installed in the corner of the cabin, and the space is relatively narrow; but the center of the pump body must be parallel to the longitudinal and transverse bulkheads. [0003] The pump body is a slender irregular columnar body, generally 6 to 20 meters in length. In order to ensure that the pump body is in a vertical free state and prevent vibration, the top, bottom and middle support must be well controlled; the above several Each connecting part must be measured on the spot, installed, welded, and then checked to check the size one by one. In particular, the welding deformation of each node will cause the final size to shift, and the positioning accuracy needs to be verified repeatedly with the help of instruments. [0004] Altho...
