Abstract
The utility model provides a novel sand pump. The novel sand pump comprises a pump body, a main shaft, an impeller, a packing and sealing device and a bearing set, wherein the main shaft is connected with the pump body through the bearing set, an oil filler hole is formed in the portion, above the bearing set, of the pump body, the packing and sealing device is installed on the main shaft between the bearing set and the impeller, a shaft sleeve is arranged between the packing and sealing device and the main shaft, and a gap is reserved between the packing and sealing device and the bearing set. According to the novel sand pump, the sealing effect is guaranteed, damage of drilling fluid to a bearing is greatly reduced, reliable operation of the sand pump is guaranteed, the service life of the bearing is prolonged, and maintenance cost is reduced.
Description
Technical field
The utility model relates to a kind of oil exploration equipment, is specifically related to a kind of novel sand pump.
Background technique
Sand pump is that device provides power for the sand remover in Solids control for drilling fluids equipment, desilter, eddy flow be with slurry etc., and sand pump can inject these cyclone separators with certain pressure by the drilling fluid that contains solid phase particles, to isolate solid phase particles.Due to the continuous operation tens days usually of sand pump in drilling process, and the working medium mud that sand pump is carried contains corrosive material, and temperature is higher, contains the hard material such as a large amount of grit simultaneously, easily causes the wearing and tearing of sand pump each several part; Due to the sand pump load that withstands shocks simultaneously, vibrate comparatively seriously, therefore also easily there is the situation of leaking.On the main shaft of existing sand pump, be generally the structure of impeller, seal arrangement, bearing, and seal arrangement and bearing closely amplexiform, once seal arrangement is because wearing and tearing cause leaking, with regard to a small amount of at last leakage, be with so corrosive liquid or hard material also can destroy bearing, thereby by the wearing and tearing of seal arrangement, caused the damage of bearing, increased maintenance cost and time.
Model utility content
The utility model aims to provide a kind of novel sand pump, and this sand pump, when guaranteeing sealing effect, has greatly reduced the destruction of drilling fluid to bearing, guarantees the reliable operation of sand pump, extends bearing life, reduces maintenance cost.
The technical solution of the utility model is as follows: a kind of novel sand pump, comprise the pump housing, main shaft, impeller, tamp seal arrangement, bearing pack, described main shaft is connected with the pump housing by bearing pack, the pump housing of described bearing pack top is provided with oil hole, the described seal arrangement that tamps is installed on the main shaft between bearing pack and impeller, described tamping between seal arrangement and main shaft is provided with axle sleeve, described in tamp between seal arrangement and bearing pack and leave space.
Described bearing pack comprises bearing, bearing cap, oil sealing, and described bearing is provided with two, and the space between bearing is made as oil pocket, and oil sealing is located at oil pocket both sides and is connected with bearing, and oil sealing outside is provided with bearing cap.
Tamp seal arrangement and comprise filler boards, hold-down grid, packing cavity; Described filler boards is fixedly connected with the pump housing, and described hold-down grid is fixedly connected with filler boards, and packing cavity is surrounded by filler boards, hold-down grid and axle sleeve.
Tamping between seal arrangement and bearing pack of the novel sand pump of the utility model adopts separation structure, leave space tamping between seal arrangement and bearing pack, when sand pump long-play causes stuffing seal micro-leakage, the corrosive liquids or the hard material that leak out drop down onto pump body by space, avoided corrosive liquids or hard material to the wearing and tearing of bearing and destruction, thereby the phenomenon that causes chain damage, the liquid or the hard thing that drop down onto pump housing inner bottom part can be removed in the lump when changing filler, convenient and time-saving; The utility model is provided with axle sleeve between filler and main shaft simultaneously, prevents that filler from contacting with the direct of main shaft, avoids main shaft to be in operation and weares and teares because of the friction of filler, changes axle sleeve when maintenance.
In sum, the novel sand pump of the utility model has effectively reduced the destruction of drilling fluid to bearing, guarantees the reliable operation of sand pump, extends bearing and main shaft life-span, reduces maintenance cost.
