"How many they have fallen in this chasm …". The speech in this case goes not about the tragic fate of people, and about deep pumps which sometimes get stuck in wells or fall in them. Their extraction is accompanied by many difficulties, and not always comes to an end with success. Business is aggravated also with the fact that except loss of the pump, the possibility of further operation of the well for which drilling many means and time are spent is sometimes lost. Therefore for extraction of the pump do not feel sorry for time and forces, trying various ways.
It is required to you
- Manual winch, set of the metalwork tool, welding machine, metal pipes ¾ "" and ½ "".
Instruction
1. The choice of way of extraction of nasosayesla pumpof has got stuck, do not try to cling at once rope on which the pump hangs, to the car and to pull very much. Before starting extraction of the pump, consider the possible reasons of its jamming and ways which should be tried first of all. The reasons of jamming of the pump can be a little: suction by its sand-quicksand, distortion in casing pipe, hit between the pump and pipe of hose or wire, gearing of the pump for edge of casing pipe.
2. Pulling of the pump for trosiketot way is obvious, and begin extraction of the pump in any cases with it. Strongly fix (electric welding or bolts) the manual winch on casing pipe so that it it was possible to pull rope, and it did not block pipe opening. Hook on rope for winch drum and pull it with significant force. Turn on the pump and wait some time. This way well helps with case of suction of the pump sand. Vibration of the working pump helps it to be released from sand. If it does not help, leave the pump for some time under rope tension, from time to time switching on and off the pump and tapping on rope. Try to pull alternately for hose, rope and electrical wire. At distortion and jamming of the pump in casing pipe it can help to straighten it. Do not use too big efforts not to tear off hose and electrical wire.
3. Pushing through of the pump you vnizvozmit the long pipe ½ "" and try to push it the pump down. It can help if jamming has come from distortion of the pump or from hit in gap between it and pipe of hose. This way is applicable only if the pump is not really deeply in the well.
4. Of usiliyemesla the above ways have not resulted pulling of the pump with maximum in success, try to pull out the pump with maximum effort. Gather previously tense rope, hose, and electrical wire reel up them on drum of the manual winch. Rotating the winch with maximum effort, try to pull out the pump. Either extraction of the pump, or break of rope, hose and electrical wire has to become result of these actions. In the first case the operation should be considered finished, in the second – to pass to the next stage of extraction.
5. Pulling of the pump by means of special nasadkiv impasse case when all applied ways have not helped, try to pull out the pump by means of special nozzle. Order to the smith production of nozzle corkscrew. It is made of bar with a diameter of 14-16 mm which curls spiral in the form of corkscrew. Outside diameter of nozzle has to be less inside diameter of casing pipe, inside – approximately equal to diameter of the pump. From above the pipe which inside diameter is slightly more than outside diameter of pipe ¾ is welded on nozzle "" (for connection with boring bar). Make boring bar of pipes ¾ "". The bar can consist of several pipes which have to connect with each other the clutch nuts or couplings manufactured of pipe of large diameter with the drilled openings for rodding. Attach nozzle corkscrew to boring bar and lower it to the well. Rotating bar, try to capture the pump nozzle. It is operation helps to take the pump in case it was absorbed by sand. The pump passes in nozzle and is got jammed there. It is necessary only to take nozzle together with the pump. The nozzle corkscrew can be useful and in case rope, the hose and cable have broken or have accidentally fallen down. At rotation of nozzle they are densely reeled up on its spiral, giving opportunity to take them on surface.
