Abstract
The utility model discloses an abrasion-resistant high-temperature double-suction oil slurry pump which is designed for solving the issue of abrasion resistance of the conventional high-temperature double-suction oil slurry pump. The abrasion-resistant high-temperature double-suction oil slurry pump mainly comprises pump covers, an overflow clearance, a trumpet-shaped protective lining, a protective lining conical ring outer wall, a protective lining circular ring inner wall and a surface casting and seeping abrasion-resistant layer, wherein the pump covers are symmetrically arranged at two ends of a double-suction impellor; the overflow clearance is arranged between the outer wall of an outlet of the impellor and the side wall of the conical surface of the pump cover; the trumpet-shaped protective lining is arranged in the overflow clearance and is concentric with the pump cover; the protective lining conical ring outer wall is clung to the side wall of the conical surface of the pump cover; the inlet of the double-suction impellor is sleeved on the protective lining circular ring inner wall; and the surface casting and seeping abrasion-resistant layer is arranged on the protective lining inner wall. When high-pressure liquid flows to a suction port of the pump, a protective lining conical ring serves as the side wall of the conical surface of the pump cover, and a protective lining circular ring undertakes the seal function of the pump cover; the protective lining can improve the efficacy of the side wall of the conical surface of the pump cover, protects the rest part of the pump cover from being invaded, improves the abrasion-resistant performance, prolongs the service life of the pump cover, and lowers the updating and maintaining expense; and an impellor ring and a seal ring are omitted, so that the pump body structure can be simplified and compact, and an inner wall casting and seeping technology is convenient to implement.
Description
Technical field
The utility model relates to a kind of wear-corrosion resistance high temperature double suction oil mud pump, belongs to the oil mud pump technical field.
Background technique
In the petrochemical processes such as petroleum refinement, synthetic fuel, Coal Chemical Industry, need a kind of energy satisfied temperature, pressure, process pump wear-resisting and corrosion-resistant composite request to bring into play the key effect of equipment, such as catalytic cracking FCCU oil mud pump and Coal Chemical Industry kerosene mixing transfer pump etc.
FCCU flow process slurry oil is the mixture that comprises alkane, aromatic hydrocarbons, colloid, sulphur and catalyzer micro mist etc., and the main chemical compositions of catalyzer is Al in the slurry oil
2O
3, be the main component that consists of abrasive material, sulfur-bearing is high, and the effect that adds heavy corrosion is arranged, and the slip of similar components has great destruction to impeller and the housing of pump.
Large flow carries the high temperature oil stock pump under the operating mode generally to adopt the double suction structure, and the design discharge of this pump is half of actual demand flow, and flow passage components are divided into symmetrical two-part, and the velocity head that produces reduces by 1/2, can improve the flowing state of fluid.As shown in Figure 1, impeller outlet outer wall 6 and 5 of pump cover conical surface sidewalls consisted of ebb interval, and impeller port ring 9 and 4 of the seal rings in the pump cover 3 of suit double-entry impeller 11 entrances consist of backflow gap 8, and high temperature media flows to Pump Suction Nozzle 10 through backflow gap 8.
When carrying the solid-liquid two-phase flow medium, at first corrode pump cover conical surface sidewall 5, grind away simultaneously impeller port ring 9 and seal ring 4 worsen pump performance.Expense and the maintenance cost of changing pump component are higher.
Summary of the invention
The purpose of this utility model is to provide a kind of wear-corrosion resistance high temperature double suction oil mud pump, and it can improve the whole life cycle of pump cover, prolongs impeller working life, reduces and upgrades and maintenance expenses.
Concrete technological scheme of the present utility model is as follows:
Pump cover symmetry with pump cover machine sealing chamber and pump cover waterway is located at the double-entry impeller two ends, forms ebb interval between impeller outlet outer wall and pump cover conical surface sidewall.Be equipped with tubaeform the protect lining concentric with pump cover crossing in the ebb interval of double-entry impeller two ends, protect lining conical ring outer wall and be close to pump cover conical surface sidewall, protect lining circle ring inner wall suit double-entry impeller entrance, protect the lining inwall and be provided with the surface cast-infiltration wearing layer.
When highly pressurised liquid flows to Pump Suction Nozzle, protect the lining conical ring and bear pump cover conical surface sidewall function, protect the lining annulus and bear the pump cover sealing function.Protect lining and can improve the effect of pump cover conical surface sidewall, all the other positions of protection pump cover are avoided corroding, and improve wear-corrosion resistance, prolong the working life of pump cover, reduce and upgrade and maintenance expenses.Cancellation impeller port ring and seal ring, it is compact that pump body structure is simplified, and is convenient to implement the inwall casting and oozes technology.
