Description

Technical Field

[0001] The utility model relates to an anti-dry wear high water seal flow automobile water pump, belonging to the technical field of automobile water pumps. Background Art

[0002] The car water pump is in the cylinder of the car engine. There are multiple water channels for cooling water circulation. It is connected to the radiator (commonly known as the water tank) located at the front of the car through water pipes, forming a large water circulation system. At the upper water outlet of the engine, there is a water pump, which is driven by a fan belt to pump out the hot water in the water channel of the engine cylinder and pump in the cold water.

[0003] There are still some problems in the use of existing anti-dry wear high water seal flow automobile water pumps. Most automobile water pumps rely on mechanical seals for sealing. The mechanical seal forms a sealing surface through a friction pair composed of a static ring and a dynamic ring. If there is a lack of coolant in the pump or the coolant is not filled into the water pump in time when the water pump is just started, it will cause dry wear of the friction pair of the mechanical seal, thereby aggravating the wear of the sealing surface and reducing its life. At the same time, when the liquid inlet pipe is connected to the engine cylinder block, the water outlet pipe of the engine cylinder block is generally connected to the inside of the automobile water pump through a thread, which makes disassembly and installation more troublesome. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-dry wear high water seal flow automobile water pump. The utility model has a simple structure and is easy to use. It can automatically add lubricant between the seal and the main shaft, thereby preventing the mechanical seal from dry wear, which would reduce the practical life of the seal. At the same time, it is convenient to install and disassemble the liquid inlet pipe and the cylinder body, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An anti-dry wear high water seal flow automobile water pump comprises a body shell, the outer side of the body shell is fixedly connected to a mounting plate, the top of the body shell is fixedly connected to a connecting ring, the top of the connecting ring is fixedly connected to a liquid inlet pipe, a motor is installed inside the body shell, the output end of the motor is fixedly connected to a main shaft, a sealing ring is installed outside the main shaft, a lubricant box is fixedly connected to the top of the body shell, a cover plate is clamped on the top of the lubricant box, an extraction pump is fixedly connected to the outer side of the lubricant box, a conduit is fixedly connected to the outer side of the extraction pump, and a liquid outlet hole is opened inside the sealing ring.

[0007] Furthermore, a sealing piece is provided inside the liquid inlet pipe, a return spring is fixedly connected to the inner wall of the liquid inlet pipe, a clamping cover is fixedly connected to the outer side of the return spring, a threaded tube is fixedly connected to the outer side of the liquid inlet pipe, a screw is threadedly connected to the inner side of the threaded tube, and an extrusion rod is fixedly connected to the outer side of the screw.

[0008] Furthermore, the main shaft is rotatably connected to the inside of the machine body shell through a motor, and the top of the main shaft is fixedly connected to an impeller.

[0009] Furthermore, the lubricant tank is symmetrically distributed on the top of the machine body shell, and one end of the conduit away from the extraction pump is fixedly connected to the inside of the sealing ring.

[0010] Furthermore, the interior of the sealing ring is in a hollow state, and the liquid outlet holes are evenly distributed in the inner wall of the sealing ring.

[0011] Furthermore, the clamping cover is symmetrically distributed inside the liquid inlet pipe, and the return spring is symmetrically distributed between the clamping cover and the inner wall of the liquid inlet pipe.

[0012] Furthermore, the threaded tubes are symmetrically distributed on the outside of the liquid inlet tube, and the extrusion rods are movably connected to the outside of the clamping cover via screws.

[0013] The beneficial effects of the utility model are:

[0014] (I) The utility model is provided with a body shell, and a motor is installed inside the body shell. The impeller on the top of the main shaft is driven to rotate by the motor, so that the automobile water pump is started. Before starting, the lubricant in the lubricant box is pumped into the inside of the sealing ring through a conduit by an extraction pump. Since the sealing ring is located on the outside of the main shaft and liquid outlet holes are evenly distributed on the inner wall of the sealing ring, the lubricant will reach the outside of the main shaft through the liquid outlet holes, thereby preventing the main shaft from dry grinding with the sealing ring when rotating, thereby improving the service life of the sealing ring.

[0015] (ii) The utility model is provided with a liquid inlet pipe. When it is necessary to connect the automobile water pump to the engine cylinder, the water pipe inside the engine cylinder is first clamped to the inside of the liquid inlet pipe, and the screw is rotated inside the threaded pipe, so that the screw is driven to move inside the threaded pipe, and the movement of the screw drives the extrusion rod to move, so that the extrusion rod squeezes the clamping cover outside the return spring, so that the two clamping covers are close to the water pipe. At this time, the water pipe can be clamped and positioned, and then the sealing piece is clamped to the inside of the liquid inlet pipe to prevent liquid penetration, thereby achieving the effect of convenient connection. When disassembly is required, it is only necessary to move the extrusion rod away from the clamping cover. BRIEF DESCRIPTION OF THE DRAWINGS
