Abstract
The invention relates to an adding pump device used for wax removal and control in oil field. Reciprocating movement of oil pumping machine is used as the power in the device. When the oil pumping machine works the oil pumping bar drives the crash fixture block move downward. Piston of single-piston guttate adding pump with crash fixture block compress the medical solution in pump and the medical solution flows into the oil well casing through high-pressure hose at the outlet. When the oil pumping machine returns the piston deviates the pressure from the crash fixture block and under the action of reset spring it moves upward. The pressure of medical solution in medical storing box is larger than the pressure in the pump cavity. The solution inlet valve is opened and medical solution enters into the pump. By cycling reciprocation continuous guttage adding is realized. Adding quantity in each stroke of oil pumping machine can be adjusted by adjusting the length that the adjustable connecting bar rotates in or out of piston. Sealing packing is open style. Outer sleeve is rotated tightly to press packing pressure cover and by the packing pressure cover sealing packing and packing pressure block are pressed so that sealing packing is filled round and sealing performance is achieved.
Description
Technical field
The present invention relates to cured clearly, the anti-cured dosing pump device of use of a kind of oilfield, this device is a power with the pumping unit to-and-fro motion, the realization continuous dosing, and add dose and can regulate according to oil well condition, be furnished with emergency support and prevent the destruction of fortuitous event medicine adding device.
Background technique
At present, cured clearly for oil well, the anti-cured method that generally adopts the dosing dilution, but the device of the mode of dosing and use has very big difference.Most method dosings of all adopting metering pump, the medicine adding device complexity needs power supply and control, and the Security of well head descends, and the corrosivity of soup is stronger simultaneously, and majority is chemical solvent, becomes key with regard to the sealing that makes medicine adding device.Bring very big inconvenience for the operation and maintenance of medicine adding device, strengthened the dosing cost.
Summary of the invention
The present invention solves the scheme that its technical problem adopts: this device mainly is made up of single plunger drop type dosing pump and annex.
The single plunger drop type dosing pump mainly comprises: the pump housing 1., packing press ring 2., stuffing box packing 3., Gland 4., outer sleeve 5., Returnning spring 6., plunger 7., regulate connecting rod 8., the liquid discharging valve group 9., feed liquor valve group 10..
Annex mainly comprises: import high pressure hose, outlet high pressure hose, hit and press fixture block, emergency support.
See accompanying drawing
Embodiment
The single plunger drop type dosing pump is fixed on the emergency support, and is fixed in the big flange of well head by emergency support, emergency support is connected by safety pin by sleeve and upper and lower pole.
Press fixture block to be fixed on the sucker rod hitting in the annex, adjust the lower fulcrum of pumping unit.
Explosive box is fixed on by the pumping unit, connects explosive box and feed liquor valve group, connect liquid discharging valve group and oil well casing with the outlet high pressure hose with the import high pressure hose.
Well head dosing in the past all is made up of dosing pump and control, dosing pump needs independent power and electrical equipment control, and well head is owing to exist oil gas, so, there is electricity to bring danger to well head, this device is a power with the to-and-fro motion of pumping unit, when pumping unit is worked, sucker rod drives to hit presses fixture block to move downward, hit the soup in the plunger compression pump housing of pressing fixture block single plunger drop type dosing pump, the liquid discharging valve group was opened after soup reached certain pressure, and soup flows into oil well casing through the outlet high pressure hose; Plunger breaks away from and to hit the compressing of pressing fixture block during the pumping unit backhaul, moves upward under the effect of Returnning spring, forms vacuum in the pump housing, and the soup pressure in the explosive box is greater than the endoceliac pressure of pump, the feed liquor opening of valves, and soup enters the pump housing.Move in circles, realize continuous drip dosing., use this device just to avoid the danger that has electricity to bring fully to well head
The every stroke of pumping unit adds how much can regulating by adjusting the length of regulating extension bar screw-in, back-out plunger of dose.
Well head dosing in the past all is to use the solenoid valve control flow rate, and is the same, and this device has avoided having the electric danger that brings to well head fully, and adjusts, controls simple, convenient.
Plunger pump in the past all is fixing filler, can only change after the filler wearing and tearing, safeguard, complicated operation, and this device stuffing box packing is an open type that the angle of filler briquetting is greater than the opening angle of stuffing box packing.When stuffing box packing is worn and torn, screw outer sleeve compressing Gland, and, stuffing box packing is filled towards periphery by Gland compressing stuffing box packing and filler briquetting, reach the effect of sealing.
The invention has the beneficial effects as follows: take the reciprocating motion of oil pumper as power, chemical feeding quantity is regulated simple, and working service is convenient.
Claims (3)
1. cured clearly, the anti-cured drop type dosing pump device of an oil well, it is made up of the pump housing, packing press ring, stuffing box packing, Gland, outer sleeve, Returnning spring, plunger, adjusting connecting rod, liquid discharging valve group, feed liquor valve group and annex, it is characterized in that: with the pumping unit to-and-fro motion is power, need not power electricity and electrical equipment control, make the well head of oil well safer.
2. adding dose according to claim 1 can regulate by adjusting the length of regulating connecting rod screw-in, back-out plunger according to actual needs.
3. can adjust the sealing of stuffing box packing according to claim 1.
Stuffing box packing is an open type, and the angle of filler briquetting is greater than the opening angle of stuffing box packing.When stuffing box packing is worn and torn, screw outer sleeve compressing Gland, and, stuffing box packing is filled towards periphery by Gland compressing stuffing box packing and filler briquetting, reach the effect of sealing.
