Problems solved by technology

However, some deficiencies in the existing metering pumps have become constraints to the development of metering pumps. The N crankshaft of the metering pump is round, and it is difficult to process: 1. It is not easy for ordinary staff to operate, because it requires High, complex process, only senior technicians have the ability to process N-type crankshafts, and only senior technicians can process N-type crankshafts
2. The scrap rate of the N-type crankshaft is higher than that of the Z-type crankshaft I own, because it has more processing links, and the possibility of errors in each link will increase accordingly
The heat treatment of N-type crankshaft raw materials is relatively difficult (large machining allowance is easy to deform)
3. The processing is dangerous. The original crankshaft is not easy to fix during the manufacturing process. It is only fixed by two center holes, and it is easy to fly out of the lathe, causing casualties
Because of its large machining allowance, the difficulty of manufacturing also increases accordingly, resulting in low precision
5. The process is complicated, the processing of the spouse is difficult, and the angles cannot be consistent
Therefore, even if the crankshaft can be accurately machined, it is not easy to install it correctly; 2. The even parts of each model can only be matched ind

Embodiment Construction

[0013] As shown in Figure 1, the metering pump is equipped with two worm gears 2, 2-1 and worm gear sleeves 2' on both sides of the worm 1. The worm gears are respectively connected to the Z-shaped crankshaft 3, and the Z-shaped crankshaft is matched with the inclined block 4. Connect, and then connect the connecting rod 5, the connecting rod is connected to the pump fluid end connector 10, the pump fluid end connector is connected to the pump head 11; the lower end of the Z-shaped crankshaft is connected to the bearing seat 6, the bearing seat is connected to the adjusting nut 8, and the adjusting nut is connected to the wire Rod 7, screw mandrel connection adjustment handwheel 9.

[0014] As shown in Fig. 2, Fig. 3 and Fig. 4, it is the Z-type crankshaft 3 of the metering pump, the Z-type crankshaft is connected with the bearing gear 6', and the cross section of the Z-type crankshaft is a square.

[0015] As shown in FIG. 5 , it is a slanting block 4 that is provided with a ...

Abstract

The invention relates to a measuring pump, in particular to a crank modified structure of the measuring pump. The invention is characterized in that the crank of the measuring pump is a shape of 'Z', and the section of the crank is polygonal. The crank has the advantages of easy positioning, easy adjustment, easy fixing. The machining angle can use digital control wire-electrode cutting and flat machining to reach micrometer accuracy.

Description

Technical field: [0001] The invention relates to a metering pump, in particular to an improved crankshaft structure of the metering pump. Background technique: [0002] Through half a century of practice and application, the demand for the development of metering pumps is increasing day by day, and has been applied in petroleum, chemical industry, metallurgy, oil refining, water supply, thermoelectricity, pharmaceuticals, food and other fields. Now, the mature power drive method and liquid delivery end (pump head) material technology make the new metering pump almost meet the metering delivery requirements of any conventional and special media, and its working pressure and capacity can also meet most of the requirements of industrial production. Today, metering pumps are found wherever precise, continuous addition of fluid is required. However, some deficiencies in the existing metering pumps have become constraints to the development of metering pumps. The N crankshaft of ...
