Abstract
The utility model discloses a packing pressure cap of a water injection pump, applied to water injection pump packing sealing of an oil field well. A step is arranged at a center hole at the outer end of a main pressure cap, a sealing packing is arranged on the step of the center hole, inner threads are arranged on the center hole at the outer end of the main pressure cap, an auxiliary pressure cap is connected to the inner threads and tightly presses the sealing packing, a sunken annular water storage groove is arranged at the middle part of the center hole of the main pressure cap, an axial diversion hole is arranged at the outer end of the main pressure cap and is communicated with the water storage groove, threads are arranged at the opening part of the diversion hole, a screwed plug is connected with the opening part of the diversion hole, and a drainage hole is arranged on the outer wall of the main pressure cap and is communicated with the diversion hole. The utility model has the advantages of utilizing an auxiliary plunger pressure cap to seal low pressure water and utilizing a flow passage of cooling water to drain the cooling water and realizes the purpose that water of the water injection pump used for lubricating and cooling the plunger packing is prevented from spattering on a pump middle lever to cause the problem that water enters engine oil so as to generate emulsification on the engine oil.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly the flushing pump is a kind of sealed packing pressure cap of water injection pump packing.
Background technique
At present, the plunger type water injection pump of oilfield enterprise's water filling employing.Because the head pressure of water injection pump is higher, generally all surpasses 10Mpa, the plunger of plunger pump carries out the axial high speed to-and-fro motion, and plunger moves in the sealed packing body, easily heating.Therefore the packing that requires to be used to seal allows that the medium that is sealed is had a certain amount of leakage, mainly is in order to prevent plunger and packing high temperature, to play effect lubricated and cooling.The new plunger seal packing of installing, because wearing and tearing are few, good sealing effect, the medium of sealing (water) is with very low speed water clock.
In actual production process, find that there are some problems in plunger type water injection pump packing pressure cap.After packing and plunger use a period of time, because wearing and tearing, cause plunger type water injection pump packing_seal variation, wastage increases, and at this moment cooling water has certain pressure, and cooling water is splashed on the intermediate bar that connects plunger especially easily, bring into water in the lubricating oil sump again by intermediate bar, cause the lubricant oil water inlet, emulsification takes place, cause lubricant oil to lose lubricating effect.
The model utility content
The purpose of this utility model is: a kind of water injection pump packing pressure cap is provided, utilizes a kicker ram pressure cap sealing low pressure water, utilize the runner of cooling water, cooling water is discharged.Overcome because of cooling water from the discharge of splashing of the plunger direction of axial motion, cause in the lubricant oil and intake, lubricant oil generation emulsion.
The technical solution adopted in the utility model is: water injection pump packing pressure cap, mainly to form by main pressure cap, auxiliary pressure cap, sealed packing and plug, and the rearward end of main pressure cap has outside thread, can be connected with the water filling pump housing.It is characterized in that: center hole has step in main pressure cap outer end, on the center hole step sealed packing is arranged.On the center hole of main pressure cap outer end internal thread is arranged, auxiliary pressure cap is connected on the internal thread, and auxiliary pressure cap compresses sealed packing.The annular water storage flume that depression is arranged at the middle part of main pressure cap center hole.In the outer end of main pressure cap the axial diversion hole is arranged, pod apertures and water storage flume UNICOM.At the pod apertures opening screw thread is arranged, plug is connected the pod apertures opening, and pod apertures is sealed.On the outer wall of main pressure cap, weep hole is arranged, weep hole and pod apertures UNICOM.
In order to screw main pressure cap, in order to screw auxiliary pressure cap, the handle hole of vertical center line is arranged in the outer end of main pressure cap and auxiliary pressure cap, cylindrical handle one end is inserted handle hole, pull handle and can screw main pressure cap or auxiliary pressure cap.
Cooling water from the outflow of plunger pump master root, because pressure is lower, under the seal action of auxiliary pressure cap, cooling water can not be by sealed packing along plunger axis to splashing away, can only be deposited in the water storage flume, and can flow out by pod apertures on the main pressure cap and weep hole.Thereby avoid being splashed on the water injection pump intermediate bar of equidirectional operation, and water being taken in the lubricating oil bath, avoid causing lubricant oil to lose efficacy because of emulsification takes place in the lubricant oil water inlet by plunger rod because of cooling water plunger movable direction discharge vertically.
The beneficial effects of the utility model: the utility model water injection pump packing pressure cap, can utilize kicker ram pressure cap sealing low pressure water, utilize the runner of cooling water, cooling water is discharged.Realization prevents that water injection pump is used for water lubricated and cooling plunger packing, is splashed on the pump intermediate bar, causes the machine oil water inlet that the problem of emulsification takes place.Water injection pump packing pressure cap low cost of manufacture, easy for installation, manufacturing is simple, can promote on a large scale, and is on-the-spot easy for installation.
