Abstract
The invention relates to a distributing plate of a water-ring vacuum pump and a processing method thereof. The distributing plate comprises a plate body (1), exhaust openings (2), slotted holes (3), a positioning hole (4), a water discharging hole (5), a middle hole (6) and an air inlet (7), wherein one side of the middle hole (6) is provided with a plurality of the slotted holes (3) arrayed in a crescent shaped; the upper parts of the slotted holes (3) are provided with the exhaust openings (2); and the other side of the middle hole (6) is provided with the crescent air inlet (7). The processing method comprises the following steps: obtaining a blank; detecting the blank; lathing an inner plane and an outer plane of the distributing plate; boring preboring holes, i.e. a slotted preboring hole, the water discharging hole (5), the exhaust openings (2), and the like, and arc position holes of the exhaust openings (2); and milling the exhaust openings (2), a middle circle, the water discharging hole (5) and the slotted holes (3). The invention enhances the dimension precision, shape precision and position precision of the distributing plate through the processing method, improves the flow guide effect, enlarges the air absorption and the exhaust area and enhances the efficiency of the water-ring vacuum pump.
Description
Technical field
The present invention relates to a kind of distribution plate and processing method of water ring vaccum pump, belong to the Machining Technology field.
Background technique
Water ring vaccum pump is a kind of vacuum displacement pump, utilizes the variation of cavity volume between blade and the distribution plate to produce air-breathing and exhaust.Distribution plate is the vital part of this pump, the position of distribution plate port and size, reach the positional accuracy of each positioning hole of distribution plate, influenced the suction and discharge area and the efficient of vacuum pump, this distribution plate that just requires to process must have high dimension precision, accuracy to shape and positional accuracy.
Problems such as distribution plate originally is to obtain porting by the mode of casting, and by using each positioning hole of drill jig secondary process, exists the manufacture cycle longer, and productivity is low, and dimensional accuracy, accuracy to shape and positional accuracy are lower.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provide a kind of precision height, water conservancy diversion effective, increased the distributing plate of water-ring vacuum pump of suction and discharge areas, and satisfy the processing method of the distributing plate of water-ring vacuum pump of dimensional accuracy and accuracy to shape and position accuracy demand.
The technical solution adopted for the present invention to solve the technical problems is: this distributing plate of water-ring vacuum pump, it is characterized in that: comprise plate body, relief opening, oval slotted eye, positioning hole, dewatering orifice, intermediate hole, suction port, intermediate hole one side is provided with and a plurality ofly is crescent shape to arrange oval slotted eye top be relief opening, and the intermediate hole opposite side is provided with the crescent shape suction port.
The processing method of above-mentioned distributing plate of water-ring vacuum pump is characterized in that: comprise following process step:
A, cut out distribution plate plate body blank with numerical control method;
Whether B, check distribution plate plate body blank shape size meet the requirements, and whether machining allowance is arranged on each working surface;
C, on the distribution plate plate body blank that the is up to the standards inside and outside two big planes of getting on the bus out;
D, employing digital-control boring-milling machine bore positioning hole, pre-drilled, relief opening circular arc places such as oval slotted eye pre-drilled, dewatering orifice, exhaust port;
Suction port, relief opening, middle circle are milled in E, roughing, fine finishing, dewatering orifice, oval slotted eye.
Compared with prior art, distributing plate of water-ring vacuum pump of the present invention and the beneficial effect that processing method had are: distribution plate dimensional accuracy, accuracy to shape and the positional accuracy of processing method processing are all higher, thereby have improved manufacturing efficiency greatly.Save cost and raw material.Distribution plate precision height, water conservancy diversion be effective, increased the suction and discharge area.
Description of drawings
Fig. 1 is a distributing plate of water-ring vacuum pump structural representation of the present invention.
Embodiment
Numerically controlled machine X, the Y that realizes processing method of the present invention to cutter Z to driving select actuating motor for use, and adopt the SIEMENS numerical control system.
This distributing plate of water-ring vacuum pump, form by plate body 1, relief opening 2, oval slotted eye 3, positioning hole 4, dewatering orifice 5, intermediate hole 6, suction port 7, intermediate hole 6 one sides are provided with and a plurality ofly are crescent shape to arrange oval slotted eye 3 tops be relief opening 2, and intermediate hole 6 opposite sides are provided with crescent shape suction port 7.
The processing method of distribution plate of the present invention comprises the steps:
The acquisition of A, blank adopts numerical control cutting to go out distribution plate plate body 1 blank; Cycle is short, enhances productivity greatly.
Whether B, distribution plate plate body 1 inspection of blank operation promptly check distribution plate plate body 1 blank shape size to meet the requirements, and whether machining allowance is arranged on each working surface, main measurer formula 0～150 vernier calliper and the 2M tape measure of this operation.
The inside and outside two plane operations of C, car distribution plate plate body 1 blank, promptly on distribution plate plate body 1 blank that is up to the standards inside and outside two planes of getting on the bus out, this operation measurer is selected 0～150 vernier calliper for use.
D, drilling operating adopt digital-control boring-milling machine to bore positioning hole 4, pre-drilled, relief opening 2 circular arc places such as oval slotted eye pre-drilled 3, dewatering orifice 5, exhaust port 2;
E, milling operation, roughing suction port 7, relief opening 2 and intermediate hole 6, fine finishing suction port 7, relief opening 2, intermediate hole 6, dewatering orifice 5, exhaust port 2 and oval slotted eye 3.
Through the distribution plate that above-mentioned steps makes, dimensional accuracy, accuracy to shape and positional accuracy are all higher, have improved the water conservancy diversion effect, have increased the suction and discharge area, and efficient is improved.Thereby improved manufacturing efficiency.
