Abstract
The utility model relates to a triplex high pressure plunger pump seal box which comprises a seal box body, gaskets, front guide sleeves, seal rings, braided packings, backing rings, a water ring, back guide sleeves, fastening nuts and a plunger. The braided packings after being soaked in lubricating oil are placed inside the seal box body. The braided packings and other parts are soaked in lubricating oil and placed in the seal box body, so lubricating property is improved, friction is reduced, service lives of the braided packings and the plunger are prolonged, and production cost is reduced.
Description
Technical field
The utility model relates to a kind of three cylinder high-pressure plunger pumps of carrying slip, specifically a kind of three cylinder high-pressure plunger pump sealed letters.
Background technique
At present, in monoammonium phosphate is produced, generally adopt three cylinder high-pressure plunger pumps of 3DP23/8X type as the shurry pump of carrying the monoammonium phosphate slip.The braided packing (AIG25G packing) of using in this seal box of plunger pump adopts special, wear-resistant fiber and PTFE braiding to form usually, wear-resistant, pliability is very strong, and himself good self lubricity can reduce the friction with plunger, has strengthened again the corrosion resistance of sealing simultaneously.Yet because fed sheet of a media is for containing the certain granules monoammonium phosphate, working pressure is large, about 70 kilograms, slurry temperature is high, and about about 118 ℃, reciprocating frequence is 60 beats/mins, uses the braided packing well damage, working life is shorter, less than week age, usually changes at least per month 4 times; And plunger wear is very fast, and plunger is changed 1 time per month at least, and changing one group of sealed letter needs 45 minutes, and not only maintenance expenses is higher, and badly influences system's gross production.
Summary of the invention
The purpose of this utility model provides a kind of three cylinder high-pressure plunger pump sealed letters, can prolong its working life, lowers to change braided packing and plunger frequency, reduces production costs.
The technical solution adopted in the utility model is: comprise sealed letter body, packing ring, front guide sleeve, seal ring, braided packing, gasket ring, water ring, rear guide sleeve, tighten nut and plunger, in the sealed letter body of packing into behind the described braided packing immersion lubricant oil.Immerse lubricating oil owing in the braided packing, so that lubricating oil can infiltrate to plunger surface after the assembling, can improve greasy property, reduce friction, thereby can prolong the working life of braided packing and plunger, prolong its replacing time.
Enter in the sealed letter body in order to bring more lubricating oil into, a preferred version of the present utility model is: packing ring, front guide sleeve, seal ring, braided packing, gasket ring, water ring, rear guide sleeve and plunger soak respectively in the sealed letter body of packing into behind the lubricant oil, so that each parts clearance is full of lubricating oil in the sealed letter body after the assembling, lubricant oil can constantly add to plunger surface in the course of the work, thereby can reduce its wearing and tearing, improve its working life.
The utility model is by with in the sealed letter body of packing into behind the parts immersion oil such as braided packing, can improve greasy property, reduce friction, thereby can prolong the working life of braided packing and plunger, prolong its replacing time, braided packing is changed 2 times at the most per month, and plunger is changed 1 time per month at the most, can enhance productivity, reduce production costs.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model structure comprises sealed letter body 1, packing ring 2, front guide sleeve 3, seal ring 4, braided packing 51～53, gasket ring 61 and 62, water ring 7, rear guide sleeve 8, tightens nut 9 and plunger 10 as shown in Figure 1.Before the assembling, first braided packing 51～53 is immersed in the lubricant oil about 10 minutes, after lubricant oil immerses fully, in order above-mentioned each parts are packed into again in the sealed letter body 1, wherein, in packing ring 2, front guide sleeve 3, seal ring 4, gasket ring 61 and 62, water ring 7, rear guide sleeve 8 and the plunger 10 first floodlubrication oil, assemble again.Plunger 10 uses in the jack indentation sealing letter body 1.
