Abstract
The invention discloses a mounting and elevating method for a deep-well pump of a liquefied natural gas storage tank. The mounting and elevating method comprises the following specific steps of firstly, in the mounting process of the deep-well pump, firstly, taking one section of steel wire rope with connectors at two ends, connecting one end of the steel wire rope with a low-pressure pump, and connecting the other end of the steel wire rope with a lifting hook of lifting equipment; secondly, downward placing the lifting hook of the lifting equipment to the upper edge of the pump well, then using a brace rod to insert into a supporting hole which is connected with the steel wire rope and is used for lifting a supporting plate, so that the whole deep-well pump is supported; at the same time, detaching the lifting hook, lengthening a steel wire rope with one connector; performing mounting and downward placing work of next section of deep-well pump by using the lengthened steel wire rope, and finishing the mounting work of the whole deep-well pump according to the cycle, wherein the elevating process of the deep-well pump is opposite to the mounting process of the deep-well pump. According to the mounting and elevating method disclosed by the invention, the process can be finished only by using one steel wire rope, so that detaching, mounting and winding work of the steel wire rope in the mounting and elevating process of the deep-well pump for multiple times can be avoided; in addition, the detaching, mounting and winding time of the steel wire rope is greatly shortened.

Method for improving installed by pump.Belong to oil, chemical field.
Background technology
In petroleum chemical industry, many is stored in the liquid petroleum chemicals in large-scale storage tank, needs by deep well pump, by liquid
State petroleum chemicals pump out from storage tank.Because deep well pump is often arranged on from the pump sump that tank top leads to liquid internal, because
This, during deep well pump is installed and used, usually can be related to installation decentralization and the lifting work of deep well pump.
As shown in figure 4, at present, when installing decentralization or lifting deep well pump 1, because pump sump 2 is relatively deep, the lifting of hanging device is high
Degree is limited, it is impossible to once transferring deep well pump 1, hanging out pump sump 2 in installation, lifting process, in practical operation, all uses
Two steel wire ropes, wherein, one is used for transferring and rising lifting first steel wire rope 6 of castering action, one be used for supporting cable with
Temporary support deep well pump the second steel wire rope 7.In concrete operations, need for one end of the first steel wire rope to connect water pump, the other end
It is wound on lifting appliance steel wire rope roller, this is accomplished by advance by carrying on lifting appliance roller after steel wire rope unloads, then
Carry out installation, the lifting of deep well pump.After the first steel wire rope reaches the position requiring, using strut temporary support second steel wire rope
7, the first steel wire rope 6 is discharged from lifting appliance roller, then the steel wire rope that lifting appliance is carried is installed on roller, now,
Because of remaining lifting work, in the range of the lifting of the lifting appliance of equipment, then steel wire rope is carried using lifting appliance complete to hang
Fill work, and complete the winding of the first steel wire rope 6 and lay work.In operating process, due to be repeatedly related to steel wire rope dismounting and
Winding work is installed, leads to operating process more complicated.
Content of the invention
Present invention is primarily targeted at overcoming the disadvantages mentioned above that prior art exists, and provide a kind of liquefied natural gas storage
Method for improving installed by tank deep well pump, and it, only just can be completed using steel cable in deep well pump in installation, lifting process,
Deep well pump can not only be avoided installing, in lifting process, the multiple dismounting of steel wire rope and install winding work, and, significantly
Save steel wire rope dismounting and winding time, material-saving expense are installed.
The purpose of the present invention is realized by technical scheme below:
A kind of liquefied natural gas storage tank deep well pump method for improving is installed it is characterised in that: installed using segmentation, the behaviour of lifting
Make method, specifically comprise the following steps that
The first step: in the installation process of deep well pump, first take one section of two that the steel wire rope of one jointing is installed, and will
One end of this steel wire rope is connected with low-lift pump, and the other end is connected with the suspension hook of lifting appliance；
Second step: the suspension hook of lifting appliance is transferred near pump sump top edge, then, using strut insertion and steel wire rope
Two supported holes of connected lifting support plate, in order to support whole deep well pump, now, pull down suspension hook, then spreading one is provided with
The steel wire rope of one jointing, using the installation decentralization work of the deep well pump of next section of carrying out of the steel wire rope of spreading, so follows
Ring, just completes the installment work of whole deep well pump；The lifting operation process of deep well pump and deep well pump installment work, process is contrary.
A kind of steel wire rope for realizing said method it is characterised in that: steel wire rope is to be connect with a connection by several sections of two
The head steel wire rope that linked together by jointing is in series.
Described jointing is connected with steel wire rope for one end, the fork configuration that the other end is connected with support plate.
Described support plate is oblong, support plate is relatively set with two holes for hoist and is located at one strut in middle part
Hole.
Beneficial effects of the present invention:, due to adopting technique scheme, it is in deep well pump in installation, lifting process for the present invention
In, only just can be completed using steel cable, deep well pump can not only be avoided installing, in lifting process, steel wire rope many
Secondary dismounting and installation winding work, and, greatly save steel wire rope dismounting and winding time, material-saving expense are installed.
