Description
[technical field]
The utility model relates to the technical field of air boosting pump, particularly a kind of technical field of removing impurity by means of precipitation air boosting pump.
[background technology]
Being of wide application of air boosting pump; especially automotive field; its effect is by atmospheric pressure oil circuit control supply; to realize the object of braking; existing product air boosting pump leak tightness is poor; in actual use; due to severe work condition environment; brake frequently; often there will be oil leakage phenomenon, major cause is that ring wear causes, and wearing and tearing and the hydraulic pressure oil filtration of seal ring have direct relation; current air boosting pump is substantially all adopt simple strainer filtering, and filter screen cannot effectively filter for some little impurity.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, propose a kind of removing impurity by means of precipitation air boosting pump, impurity in hydraulic oil can be made by after filter screen filtration, then through precipitation, greatly reduce the impurity content in hydraulic oil, well solve the problem of ring wear.
For achieving the above object, the utility model proposes a kind of removing impurity by means of precipitation air boosting pump, comprise sediment tube, brake chamber, air boosting pump housing and propelling rod, described air boosting pump housing upper is provided with oil can, the inside of described oil can is provided with filtering net, the bottom of oil can is provided with sediment tube, the surrounding of described sediment tube is provided with sludge pan, described air boosting pump enclosure interior is provided with propelling rod, coordinating with brake piston of described propelling rod is installed, described air boosting pump enclosure interior is provided with pull back spring, described brake piston is arranged on brake chamber inside.
As preferably, the oil inlet on described sediment tube and air boosting pump housing is installed by screw thread fit.
As preferably, the length of described sediment tube is 10 ~ 30mm, and the diameter of sludge pan is 50mm, and sediment tube is in the centre of sludge pan.
As preferably, the left side in propelling rod and air boosting pump body contact face is provided with a circular seal ring, and the right side in propelling rod and air boosting pump body contact face is provided with a rectangular seal.
The beneficial effects of the utility model: the utility model by adding sediment tube bottom oil can, and arranges the way of sludge pan, the impurity in hydraulic oil is precipitated fully, greatly can extend the life-span of seal ring, reduce the generation of leakage of oil, save hydraulic oil.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the main pseudosection of a kind of removing impurity by means of precipitation of the utility model air boosting pump.
In figure: 1-oil-can lid, 2-oil can, 3-sediment tube, 4-sludge pan, 5-brake chamber, 6-brake piston, 7-propelling rod, 8-rectangular seal, 9-circular seal ring, 10-pull back spring, 11-air boosting pump housing, 12-oil inlet, 13-filtering net.
[detailed description of the invention]
Consult Fig. 1, a kind of removing impurity by means of precipitation air boosting pump of the utility model, comprise sediment tube 3, brake chamber 5, air boosting pump housing 11 and propelling rod 7, described air boosting pump housing 11 top is provided with oil can 2, the inside of described oil can 2 is provided with filtering net 13, the bottom of oil can 2 is provided with sediment tube 3, the surrounding of described sediment tube 3 is provided with sludge pan 4, described air boosting pump housing 11 inside is provided with propelling rod 7, coordinating with brake piston 6 of described propelling rod 7 is installed, described air boosting pump housing 11 inside is provided with pull back spring 10, it is inner that described brake piston 6 is arranged on brake chamber 5.Described sediment tube 3 is installed by screw thread fit with the oil inlet 12 on air boosting pump housing 11.The length of described sediment tube 3 is 10 ~ 30mm, and the diameter of described sludge pan 4 is 50mm, and sediment tube 3 is in the centre of sludge pan 4.Described propelling rod 7 is provided with a circular seal ring 9 with the left side of air boosting pump housing 11 contact surface, and propelling rod 7 is provided with a rectangular seal 8 with the right side of air boosting pump housing 11 contact surface.
Utility model works process:
A kind of removing impurity by means of precipitation air boosting pump of the utility model in the course of the work, off working state lower thrust rod 7 is pulled to brake piston 6 left side of brake chamber 5 under the elastic force effect of pull back spring 10, hydraulic oil enters brake chamber 5 by sediment tube 3 and oil inlet 12, hydraulic oil is full of in brake chamber 5, during work, the pressure promotion propelling rod 7 of air moves right, brake piston 6 slides to the right under the effect of propelling rod 7, finally completes braking.
The principle of a kind of removing impurity by means of precipitation of the utility model air boosting pump: air boosting pump is the device that little pressure is converted to large pressure, the pressure that liquid produces equals the product of pressure and cross-sectional plane, the principle that the object being greater than liquid according to density can sink at liquid internal, sediment tube 3 is higher than sludge pan 4, the impurity that density is large will sink, in the course of the work, hydraulic oil liquid level in sludge pan 4 is lower than the import of sediment tube 3, so be in relative static conditions, so precipitation, the impurity in 4 also would not enter into sediment tube 3 along with hydraulic oil.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
