Problems solved by technology

The gear of the submersible pump head is stuck, oil leaked, damaged, etc., and it needs to be replaced in time. However, during the replacement process, it is necessary to punch on the polished rod under the pump head. Both hands will operate under the hoisted submersible pump head, and the hoisted weight, including the submersible pump head, sucker rod, and lower pump, etc., weighs 7-9 tons. Uncontrolled lifting or unstable operation will cause the suspended submersible pump head to drop suddenly, causing casualties to the operators under the pump head
Such a dangerous workload will occur 2-3 times a month, and with the advantages of submersible pump mining, the increase in the number of wells, and the increase in service life, the damage to the submersible pump will become more and more serious, so the workload of replacing the pump head It will gradually increase. It can be said that every operation of the staff at the post is risking their lives; on the other hand, during the operation, because the wellhead is open, the square clamps are easy to fall into the wellbore, causing well jamming or overhaul Accidents, in order to avoid casualties during operation and to avoid the phenomenon of stuck teeth falling into the wellbore

Abstract

The invention relates to an improved submersible pump protective device. An inclined block baffle I (71) is arranged on one side of a semilunar upper plate I (1). An inclined block baffle II (72) is arranged on one side of a semilunar upper plate II (2). The included angle between inclined plates of the inclined block baffle I (71) and the inclined block baffle II (72), and the horizontal direction is 40-50 degrees. The size of a semilunar lower plate I (3) is two to three times that of the semilunar upper plate I (1). The size of a semilunar lower plate II (4) is two to three times that of the semilunar upper plate II (2). The height of a supporting column (5) is three to five times that of the inclined block baffle I (71). The inclined block baffle I (71) and the inclined block baffle II (72) are of a symmetrical structure. According to the improved submersible pump protective device, the work procedures are simplified, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical structures, and in particular provides an improved protection device for a submersible pump. Background technique [0002] As a new technology, the submersible pump has the advantages of strong sand-carrying ability and energy saving, and has been widely promoted and applied globally and in our factory. The gear of the submersible pump head is stuck, oil leaked, damaged, etc., and it needs to be replaced in time. However, during the replacement process, it is necessary to punch on the polished rod under the pump head. Both hands will operate under the hoisted submersible pump head, and the hoisted weight, including the submersible pump head, sucker rod, and lower pump, etc., weighs 7-9 tons. Uncontrolled lifting or unstable operation will cause the suspended submersible pump head to drop suddenly, causing casualties to the operators under the pump head.
