Arrange water pump seal separation blade installs and uses between row water pump rotor subassembly and shifting block, and the leakproofness is good, has avoided in the drain pump working process having guaranteed the normal work of drain pump in rivers get into the impeller cavity between shifting block and the impeller subassembly.
Description
Technical field
This utility model relates to a kind of draining pump parts, more specifically, it relates to the draining pump of a kind of good airproof performance seals catch.
Background technology
At present, a lot of washing machinees all adopt the mode of draining in a high position to carry out draining, it is simple to the recycling of water, can saving water resource to a certain extent. The drainage position of washing machine is generally fitted with draining pump, in order to the discharge of current in washing machine. The link position of draining pump rotor assembly and impeller assembly is typically provided with shifting block, impeller cavity it is provided with between shifting block and impeller assembly, draining pump work process needs prevent current from entering in impeller cavity, therefore between rotor assembly and shifting block, need the setting carrying out sealing structure, it is typically now adopt O to seal, the sealing means sealing effectiveness of this routine is not good, there is the risk of leakage, thus affecting the normal operation of draining pump.
Utility model content
It is not good that this utility model overcomes sealing property between existing draining pump rotor assembly and shifting block, there is the risk of leakage, thus affecting the deficiency of the normal operation of draining pump, provide a kind of draining pump and seal catch, it is arranged between draining pump rotor assembly and shifting block and uses, good airproof performance, it is to avoid in draining pump work process, current enter in the impeller cavity between shifting block and impeller assembly, it is ensured that the normal operation of draining pump.
In order to solve above-mentioned technical problem, this utility model is by the following technical solutions: a kind of draining pump seals catch, catch body including circulus, it is equipped with round-corner transition between catch body medial surface and upper surface, lower surface, it is equipped with round-corner transition between catch outer body face and upper surface, lower surface, catch body upper surface is planar structure, and the lower surface of catch body is provided with the supercharging locating slot of a ring shape.
Seal when catch uses and be arranged on impeller assembly rear end and be socketed on rotor, seal catch rear end and stop piece base is set, seal catch forward end seal and be connected on rotor assembly, seal catch back-end sealing and be connected on stop piece base, seal catch inner ring sealing shroud and be connected on rotor. Seal supercharging locating slot after catch is installed and form booster cavity, make sealing catch to inside and outside expansion, increase the abutting power sealing inside and outside catch between face and other parts, thus increasing sealing property. Draining pump seals catch and is arranged between draining pump rotor assembly and shifting block to use, good airproof performance, it is to avoid in draining pump work process, current enter in the impeller cavity between shifting block and impeller assembly, it is ensured that the normal operation of draining pump.
As preferably, supercharging locating slot two sides all arcuate structures in evagination, supercharging locating slot width draws in from opening gradually to bottom end.This structure of supercharging locating slot arranges the structural strength that ensure that catch body, simultaneously facilitates the adaptation with stop piece base, it is ensured that supercharging locating slot side and stop piece base exist gluing, sealing place all the time, it is ensured that sealing property.
As preferably, catch body is processed by nitrile rubber. Nitrile rubber good seal performance.
As preferably, the ratio of catch body internal diameter and external diameter is 1:2.5-3.5. The ratio of supercharging locating slot bottom width and A/F is 1:8-10. The ratio of catch body thickness and internal diameter is 1:1.8-2.5. Catch body dimension arranges rationally, and structural strength is good, and sealing property is good, it is simple to mounting arrangements.
Compared with prior art, the beneficial effects of the utility model are: draining pump sealing catch is arranged between draining pump rotor assembly and shifting block and uses, good airproof performance, avoid current in draining pump work process and enter in the impeller cavity between shifting block and impeller assembly, it is ensured that the normal operation of draining pump.

Detailed description of the invention
Below by specific embodiment, and in conjunction with accompanying drawing, the technical solution of the utility model is further described specifically:
Embodiment: a kind of draining pump seals catch (referring to accompanying drawing 1), and including the catch body 1 of circulus, catch body is processed by nitrile rubber. It is equipped with round-corner transition between catch body medial surface and upper surface, lower surface, it is equipped with round-corner transition between catch outer body face and upper surface, lower surface, catch body upper surface is planar structure, and the lower surface of catch body is provided with the supercharging locating slot 2 of a ring shape. Supercharging locating slot two sides all arcuate structures in evagination, supercharging locating slot width draws in from opening gradually to bottom end. The ratio of catch body internal diameter and external diameter is 1:2.5-3.5. The ratio of supercharging locating slot bottom width and A/F is 1:8-10. The ratio of catch body thickness and internal diameter is 1:1.8-2.5. In the present embodiment, catch body internal diameter is 3.3mm, and external diameter is 9.9mm; Supercharging locating slot bottom width is 0.1mm, and A/F is 0.93mm; Catch body thickness is 1.6mm. Radius between catch body upper surface and inside and outside side is 0.8mm, and is the circular arc of 1/4th circles; Radius between catch body lower surface and inside and outside side is 0.8mm, and the distance between round-corner transition and catch outer body face and the round-corner transition of lower surface of catch outer body face and upper surface is 0.1mm. Catch body medial surface is arranged with lateral surface symmetrical configuration.
Seal when catch uses and be arranged on impeller assembly rear end and be socketed on rotor 5, seal catch rear end and stop piece base 6 is set, seal catch forward end seal and be connected on rotor assembly, seal catch back-end sealing and be connected on stop piece base, seal catch inner ring sealing shroud and be connected on rotor. Seal supercharging locating slot after catch is installed and form booster cavity, make sealing catch to inside and outside expansion, increase the abutting power sealing inside and outside catch between face and other parts, thus increasing sealing property. Draining pump seals catch and is arranged between draining pump rotor assembly and shifting block 3 to use, good airproof performance, it is to avoid in draining pump work process, current enter in the impeller cavity 4 between shifting block and impeller assembly, it is ensured that the normal operation of draining pump.
