Abstract
The utility model discloses a jet flow generating device of a numerical control water cutting machine. The jet flow generating device comprises a water pump, filters, a high pressure pump and a cutting head, wherein the filters are serially connected between the water pump and the high pressure pump through communicating pipes. The jet flow generating device is characterized in that filter holes of filter elements in inner cavities of the filters are 0.45 microns in diameter. In specific implementation, a voltage stabilizing container is serially connected between each filter and the high pressure through a communicating pipe, and two filters are serially connected side by side. The jet flow generating device, through repeated tests, changes size of a filter element filter hole of an existing filter into 0.45 microns, which not only guarantees normal operation of the water jet device but also greatly reduces loss of a high pressure pump sealing element and a jewel nozzle, thus effectively improving reliable performance of the equipment.
Description
[technical field]
The utility model relates to a kind of numerical control water cutter jet flow generating device.
[background technology]
Numerical control water cutter consists of water jet generating apparatus, the husky system of confession, workbench and electric control gear thereof, and wherein water jet generating apparatus is comprised of water pump, filter and high-pressure pump.During operation, high-pressure water jet and sand material form chopped beam from the ejection of cutting head nozzle after mixing in blender, and workpiece is processed, and because cutting head is arranged on a multi-spindle machining on hand, therefore can realize the cutting of complicated shape and design.Filter is responsible for filtered water stream impurity in operation, water is kept clean before reaching super-pressure, to protect high voltage component and constant chopped beam is provided.Before the utility model is made; the problem that prior art exists is: be placed in filter inner chamber; the filter opening size of the cotton filter core of PPS only has 1um and two kinds of standard specifications of 5um; make high voltage component; especially seriously intimidateed the service life of high-pressure sealing ring and jewel nozzles; usually can therefore leakage phenomenon occur, thereby reduce the reliability of equipment, the normal production of impact is repaired, is changed in shutdown.
[summary of the invention]
The problems referred to above that exist for solving prior art, the utility model aims to provide a kind of numerical control water cutter jet flow generating device, and it is not fragile that this device has high-pressure sealing ring, and long service life advantage can increase substantially the unfailing performance of equipment.
For achieving the above object, the utility model has adopted following technical scheme: the structure of this numerical control water cutter jet flow generating device, comprise water pump, filter, high-pressure pump and cutting head, described filter, through being serially connected in communicating pipe between described water pump and high-pressure pump, is characterized in that: in described filter inner chamber, the filter opening diameter of filter core is 0.45um.
As preferably, between described filter and high-pressure pump through the pressurizing vessel of having connected communicating pipe.
As preferably, described filter is two filters of serial connection side by side.
Beneficial effect: compared with prior art, the utility model is by repeatedly testing, filter core filter opening size in existing filter is changed into after 0.45um, not only can guarantee the normal operation of water jet device, and the proportion of goods damageds of high-pressure pump seal and jewel nozzles are reduced greatly, thereby effectively improved the unfailing performance of equipment.
Below by embodiment, also by reference to the accompanying drawings the utility model is further described.
[accompanying drawing explanation]
Fig. 1 is the structural representation of an embodiment of the utility model.
In figure: water pump 1, water inlet 11, communicating pipe 12, filter 2, filter core 21, high-pressure pump 3, cutting head 4.
[specific embodiment]
Referring to Fig. 1.The ordinary tap water hydraulic pressure that water pump 1 is inputted water inlet 11 is from 0.2-0.4MPa is increased to 0.8MPa, through communicating pipe 12, enter filter 2, first filter core 21 filtrations by two filters 2 offer high-pressure pump 3, be pressurized to the backward cutting head 4 of 300MPa water under high pressure is provided.Two filters 2 are set and can effectively improve filter effect, between filter (after second filter) and high-pressure pump 3, through the pressurizing vessel (not drawing in Fig. 1) of connecting communicating pipe, can play the effect of stablizing hydraulic pressure.This pressurizing vessel is a kind ofly there is no filter core and other structure is identical with existing filter 2.
Innovation of the present utility model is to dwindle the filter core filter opening diameter of filter, change 0.45um into, by solid line repeatedly, prove, the filter of this filter opening diameter can not cause very large damage to high-pressure pump seal and jewel nozzles, and can guarantee the normal operation of water jet device.
Above-described embodiment is only for explaining the present utility model thinking, and any simple deformation structure that is subject to its inspiration and makes, all should include protection domain of the present utility model in.
