Embodiment 1

[0032] An embodiment of the present invention provides a lubricator for a reciprocating plunger pump, see figure 1 , the lubricator consists of:

[0033] The lubricating oil tank 1, the lubricating oil control valve 11 installed at the oil outlet of the lubricating oil tank 1, the balance pipe 2 and at least one dripper 3 installed above the plunger of the plunger pump, the dripper 3 includes a diverter regulating valve 31 and The drip nozzle 32, the lubricating oil tank 1 communicates with the balance pipe 2 through the connecting hose 12, and the balance pipe 2 is evenly distributed along its axis direction with at least one elbow 21, and one end of the elbow 21 is connected with one end of the diversion regulating valve 31, and the diversion adjustment The other end of the valve 31 is connected with a drip nozzle 32 .

[0034] The lubricator also includes: an incoming water line 4 connected to a water source and an incoming water control valve 41 installed on the incoming ...

Embodiment 2

[0042] An embodiment of the present invention provides a lubricator for a reciprocating plunger pump, see figure 2 , the lubricator consists of:

[0043] The lubricating oil tank 1, the lubricating oil control valve 11 installed at the oil outlet of the lubricating oil tank 1, the balance pipe 2 and at least one dripper 3 installed above the plunger of the plunger pump, the dripper 3 includes a diverter regulating valve 31 and The drip nozzle 32, the lubricating oil tank 1 communicates with the balance pipe 2 through the connecting hose 12, and the balance pipe 2 is evenly distributed along its axis direction with at least one elbow 21, and one end of the elbow 21 is connected with one end of the diversion regulating valve 31, and the diversion adjustment The other end of the valve 31 is connected with a drip nozzle 32 .

[0044] The lubricator also includes: an incoming water line 4 connected to a water source and an incoming water control valve 41 installed on the incoming...

Embodiment 3

[0068] An embodiment of the present invention provides a method for using a lubricator for a reciprocating plunger pump, see image 3 , the method includes:

[0069] Step S11, when the plunger pump works normally, open the lubricating oil control valve and close the incoming water control valve, so that the lubricating oil in the lubricating oil tank enters the balance pipe through the connecting hose and the pressurized liquid storage tank.

[0070] In practical application, the lubricator needs to be installed first. The specific installation method has been explained above, and will not be repeated here.

[0071] Step S12, adjusting the diverter regulating valve, controlling the dripper to drip 30-40 drops of lubricating oil per minute to the plunger surface of the plunger pump for 6-10 hours.

[0072] In practical applications, the oil dripping speed and the oil dripping time can be adjusted according to the actual situation. For example, in this embodiment, the amount o...

Abstract

The invention discloses a lubricator used for a reciprocating plunger pump and a use method of the lubricator and belongs to the technical field of oil field water injection machines. The lubricator comprises a lubricating oil tank, a lubricating oil control valve, a balance pipe and a water dropper installed above a plunger of the plunger pump. The lubricating oil tank communicates with the balance pipe. At least one bend is evenly distributed on the balance pipe in the axis direction of the balance pipe. One end of each bend is connected with one end of a diversion adjusting valve, and the other end of each diversion adjusting valve is connected with a liquid dropping nozzle. The lubricator further comprises an inflow water pipeline communicating with a water source and an inflow water control valve. The incoming water pipeline communicates with the balance pipe through a connecting hose. By means of the lubricator used for the reciprocating plunger pump and the use method of the lubricator, the incoming water pipeline communicating with the water source and the incoming water control valve are newly additionally arranged so that the lubricator can be used for controlling dropping of lubricating oil and water into the plunger of the plunger pump in sequence, the plunger is lubricated through the lubricating oil which is not completely emulsified, the use amount of the lubricating oil can be reduced, the lubricating cost is reduced, meanwhile, the lubricating oil adsorbed to the interior of a packing can be fully utilized, and the utilization rate of the lubricating oil is increased.

Description

technical field [0001] The invention relates to the technical field of oilfield water injection machinery, in particular to a lubricator for a reciprocating plunger pump and a method for using the lubricator. Background technique [0002] A large number of reciprocating plunger pumps need to be applied to water injection wells and sewage return in oil fields. When the conventional reciprocating plunger pump works normally, the plunger in the plunger pump will rub against the packing that acts as a seal, which will not only generate high temperature, make the packing dry and hard and lack toughness and elasticity, but also affect the packing. The roots cause wear, which will affect the sealing effect of the packing. [0003] For this reason, people will install a lubricator on the plunger pump, drip lubricating oil on the plunger through the lubricator, and then when the plunger reciprocates, the lubricating oil will be brought between the plunger and the packing to lubricat...
