Embodiment Construction
[0025] The following is a further description of the cemented carbide idling and series-connected amphibious sand pump of the present invention in conjunction with the accompanying drawings.
[0026] Figure 1 to Figure 8 The static rings made of wear-resistant materials in the six embodiments are cemented carbide static rings 33, and the cemented carbide static rings 33 are inlaid on the static ring transmission body 3 and the static ring transmission body 4. The moving rings made of wear-resistant materials in the six embodiments are cemented carbide moving rings 34 , and the hard alloy moving rings 34 are inlaid on the moving ring transmission body 5 and the moving ring transmission main body 6 . Each carbide ring has a working end face 30 . A pair of hard alloy static rings 33 and hard alloy moving rings 34 are tightly pressed together by their respective end faces 30 to form a sealing end face 30 to complete the sealing work together. in Figures 1 to 4 It is a double ...

The invention provides a hard alloy amphibious sand pump capable of being idled and connected in series. A first rotating ring is provided with a blocking drum which covers the circumference of a first rotating ring drive body and blocks a drive pin which will be thrown out during rotation. The blocking drum can be a thin-wall cover-shaped drum extending from a drive body for mechanically sealing a second rotating ring at double end faces. The sand pump has the following advantages that the aims that the mechanical seal can not generate too high pressure on the seal face when different cavities alternate and frequently generate high pressure and can keep stable and safe operation are achieved; and meanwhile, the improved mechanical seal is easy to manufacture, is convenient to install and dismantle, has ideal effects, can pump water and drain sand in deeper water, can resist the high temperature of steam brought by high temperature during drained sand overload in seal motor inner cavities and can meet the extreme demands of frequent variation of pressure.
Description
technical field [0001] The invention relates to a cemented carbide sand pump that can be idling and can be connected in series for amphibious purposes, which is an amphibious water pump for both land and underwater use, and is suitable for a submersible sand pump or a land vertical pump for conveying liquid containing solid abrasive particles. . Background technique [0002] In the prior art, "Vertical Pump for Mine" has three invention patents: ZL200410078876.4, ZL200410078879.8, ZL200410078880.0. [0003] Frequent changes in the pressure on both sides of the single-end mechanical seal or the pressure that is divided into three parts by the double-end mechanical seal will cause overheating damage or even fragmentation, which will directly affect the sealing effect and life of the mine vertical pump. For example: the water level drops from 100 meters to several meters, and the pressure of the mine vertical pump at the bottom of the well drops from 1MP to almost zero. Anoth...
