Abstract

The invention discloses a sand pump and relates to the technical field of machine manufacturing. The sand pump comprises a pump shell connected with a water inlet pipe and a water outlet pipe. An impeller is installed in the pump shell. The impeller is connected with a main shaft. The main shaft is installed on a bearing seat. A connecting disk is arranged between the impeller and the bearing seat and is arranged outside the main shaft in a sleeving mode. The portion, sleeved with the connecting disk, of the main shaft is sleeved with a steel sleeve. An O-shaped seal ring is arranged between the steel sleeve and the main shaft. Two framework oil seals are arranged between the steel sleeve and the connecting disk. Two oil holes are formed in the connecting disk and enable the two framework oil seal to be communicated. Forced filling oil cups are installed at the positions of inlets of the oil holes. Lubricating oil can be directly injected into the steel sleeve between the two framework oil seals through the forced filling oil cups and the oil holes. By the adoption of the sand pump, the problems that when framework oil seals are not sufficiently lubricated, high temperature is caused by friction, rubber of the framework oil seals is aged, deteriorates and loses elasticity, the abrasion of metal on the friction surfaces is accelerated due to insufficient lubrication, and accordingly the sand pump leaks sand are solved.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a sand pump for sand pumping. Background technique [0002] In the existing sand pump used for sand pumping, the skeleton oil seal arranged between the steel sleeve of the main shaft and the connecting plate cannot directly input lubricating oil for lubrication, resulting in poor lubrication and easy aging of the rubber at high temperature and deterioration of the rotating parts. Metal wear. Contents of the invention [0003] The purpose of the present invention is to provide a sand pump, which can solve the problems of insufficient lubrication between the skeleton oil seal and the steel sleeve, easy aging of rubber at high temperature and metal wear of the rotating parts, which will cause sand pump leakage. [0004] In order to solve the above problems, the technical solution adopted in the present invention is: [0005] This kind of sand suction pump includ...
