Abstract

The utility model discloses a sand pump, and relates to the technical field of machine manufacturing. The sand pump comprises a pump case, wherein the pump case is provided with a water inlet pipe and a water outlet pipe in a connected mode; an impeller is installed inside the pump case and is connected with a main shaft; the main shaft is installed on a bearing pedestal; a connection disc is arranged between the impeller and the bearing pedestal; the main shaft is sleeved with the connection disc; a steel sleeve is arranged on the part, sleeved with the connection disc, of the main shaft; an O-type sealing ring is arranged between the steel sleeve and the main shaft; two framework oil seals are arranged between the steel sleeve and the connection disc; the connection disc is provided with an oil hole which is directly communicated with the position between the two framework oil seals; a forced filled oil cup is installed at an inlet of the oil hole; lubricating oil can be directly poured on the steel sleeve between the two framework oil seals through the forced filled oil cup and the oil hole. The sand pump can solve the problems that as high temperature is generated when framework oil seals are lubricated insufficiently, rubber of the framework oil seals ages, goes bad and loses elasticity, and due to insufficient lubrication, abrasion to metal on a friction surface is accelerated, and a sand pump leaks.

Description

Sand pump

Technical field

The utility model relates to machinery manufacturing technology field, especially a kind of for taking out husky sand pump.

Background technique

Existing for taking out husky sand pump, be arranged on the outside framework oil seal between steel bushing and the tie-plate of main shaft, owing to cannot directly inputting oil lubrication, cause lubricated smooth and be easy to make the rotten and rotation position galling of rubber high temperature ageing.

Model utility content

The purpose of this utility model is to provide a kind of sand pump, and it can solve between outside framework oil seal and steel bushing not lubricated, is easy to make rubber high temperature ageing and rotation position galling and the problem that causes sand pump to leak.

In order to address the above problem, the technical solution adopted in the utility model is:

This sand pump, comprises the pump case that is connected with intake pipe and outlet pipe, and the impeller being connected with main shaft one end is installed in described pump case, and the other end of described main shaft is connected with belt pulley, and described main shaft is arranged on the bearing at bearing support two ends; Between described impeller and described bearing support, be provided with the tie-plate being enclosed within outside main shaft, on described main shaft in described tie-plate cover, be provided with steel bushing, between steel bushing and tie-plate, be provided with at least two outside framework oil seals, on described tie-plate, offer the oilhole between straight-through described outside framework oil seal, the ingress of described oilhole is provided with joint type forced filling oil cup.

In above technological scheme, further scheme is: between described steel bushing and described main shaft, be provided with O RunddichtringO.

Further: the material of described steel bushing is high hardness wear-resisting steel.

Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:

The utility model can directly be inputted the steel bushing between lubricant oil to two outside framework oil seal from joint type forced filling oil cup, and outside framework oil seal and steel bushing can be lubricated timely, have reduced wearing and tearing, avoids causing sand pump to leak.
