Abstract
The utility model relates to a marine diving pump. Currently, in China a loading machine is commonly used to push snow so as to realize snow removal, but a shoveling, rolling and blowing integrated snow removing vehicle is rare. The marine diving pump comprises a pump body (1). A pump shaft (2) is arranged in the pump body. The pump shaft is in sleeving connection with a long shaft sleeve A (3), a long shaft sleeve B (4), a long shaft sleeve C (5) and a long shaft sleeve D (6). The long shaft sleeve A is in sleeving connection with a lower bearing (7). The long shaft sleeve B is in sleeving connection with an impeller (8). The long shaft sleeve C is in sleeving connection with a rubber bearing (9). The pump shaft is in sleeving connection with a long shaft oil seal gland (10). The lower end of the pump body is provided with a water inlet joint (11). The water inlet joint is connected with a middle guide shell (12). The middle guide shell is connected with an upper guide shell (13). The upper guide shell is connected with a check valve body (14). The check valve body is provided with a check valve (15). The marine diving pump is used for a marine drilling platform to extract domestic water.
Description
Technical field:
The utility model relates to a kind of submersible pump application, is specifically related to a kind of latent sea water pump.
Background technique:
Existing latent sea water pump processing is slightly made, and precision is not high, and the connection between part and the part is not tight, breaks away from easily during work, influences working efficiency, increases economic expenditure.
Summary of the invention:
The purpose of this utility model provides a kind of utilization and upgrades part material, adopts check valve to prevent the latent sea water pump of aqueous reflux.
Above-mentioned purpose realizes by following technological scheme:
Latent sea water pump, its composition comprises: the pump housing, in the described pump housing pump shaft is housed, described pump shaft interlocks spreading axle sleeve A, major axis cover B, major axis cover C and major axis cover D, described major axis cover A cover connects lower bearing, described major axis cover B cover connects impeller, described major axis cover C cover connects rubber bush bearing, described pump shaft interlocks spreading shafting oil sealed cover, into water joint is equipped with in described pump housing lower end, and described water inlet joint connects the water conservancy diversion mesochite, and described water conservancy diversion mesochite connects goes up blower inlet casing, the described blower inlet casing of going up connects check valve case, and described check valve case has check valve.
Described latent sea water pump, between described impeller and the water inlet joint seal ring is housed, between described impeller and the water conservancy diversion mesochite seal ring is housed, between described major axis oil sealing cover and the last blower inlet casing bearing and oil sealing cover is housed, described oil sealing cover one end connection bearing.
Described latent sea water pump is used bolt between described water inlet joint and the water conservancy diversion mesochite, uses bolt between described water conservancy diversion mesochite and the last blower inlet casing, and described going up between blower inlet casing and the check valve case used bolt.
Described latent sea water pump, described impeller is connected with key with pump shaft.
Beneficial effect:
1. impeller of the present utility model, blower inlet casing, water inlet joint, seal ring etc. adopt tin bronze, and bearing adopts silicon brass and tin-phosphor bronze, and pump shaft adopts stainless steel, and axle sleeve and driving key adopt stainless steel.The diameter of pump is 300mm, flow be 200 tons/per hour, tangible difference is arranged at structure and process aspect and conventional pump, a lot of foundry goods have all adopted the cast copper material, have improved the corrosion protection anti-corrosion.
2. impeller of the present utility model adopts key to be connected with pump shaft, axially with major axis cover location, has played the effect that prevents that impeller from coming off, and technology capability is good.
3. during pump work of the present utility model, liquid under impeller action, speed can and pressure can increase simultaneously, and, flow out through lifting pipe by blower inlet casing, last blower inlet casing, check valve.The hydraulic pressure increase that is directly proportional with the progression of impeller.
4. pump shaft of the present utility model is used water lubrication by rubber bush bearing and metal bearing supporting; Guide bearing in the last blower inlet casing adopts the oil lubrication structure, connects with bolt between housing.
5. the utility model aqueous reflux when preventing that pump from stopping operating, lower punch power is excessive, in pump work part upper end, check valve is housed.
6. pump appearance of the present utility model is coated with rust proof paint and corrosion resistant coating, prevents that marine growth from dwelling attached.
