Abstract

The utility model relates to a precise ceramic pump which comprises a cylinder body. A ceramic core body is arranged in the cylinder body, and a liquid inlet mouth and a liquid outlet mouth are arranged on the circumference of the cylinder body, are communicated with an inner cavity of the ceramic core body and are perpendicular to each other. A measuring rod is inserted in the ceramic core body, a groove is arranged on the outer circle of the measuring rod, a bottom cover is arranged on the end portion of the cylinder body, and the bottom cover and the cylinder body are sealed through a sealing ring and are connected through nuts. The ceramic core body and the measuring rod are both made of ceramics. The precise ceramic pump is simple in structure, abrasion resistant, high-temperature resistant, long in service life and stable in property.

Description

The high technology ceramics pump

Technical field

The utility model relates to the pump technical field, relates in particular to the filling pump of being made by stupalith.

Background technique

The application of existing medicine and chemical industry plunger pump is more extensive, mostly present plunger pump is metal pump, the hardness of metal pump is low, wear-resisting, poor corrosion resistance, and non-refractory, the long-term metal pump that uses, its performance at aspects such as flow and pressure is also stable inadequately, because there is above-mentioned deficiency in metal pump, causes its working life short, need regularly change, cause cost of production higher.

The model utility content

The utility model provides a kind of high technology ceramics pump at above-mentioned shortcoming of the prior art, and it is simple in structure, and is corrosion-resistant, high temperature resistant, long service life, stable performance.

The technological scheme that the utility model adopted is as follows:

The high technology ceramics pump comprises cylinder body, has ceramic core body in the cylinder body, and the circumference of cylinder body has liquid inlet port and fluid mouth, and liquid inlet port communicates with the inner chamber of ceramic core body with the fluid mouth and be vertical mutually; Pottery core body interpolation has fule metering bar, and the fule metering bar cylindrical has groove; The end of cylinder body has bottom, and bottom is connected by the seal ring sealing and by nut with cylinder body; Pottery core body and fule metering bar are made by ceramic material;

Further technological scheme is as follows:

Have retaining sleeve on the described fule metering bar;

Have mounting hole on the cylindrical section of described bottom.

Advantage of the present utility model is: ceramic core body and fule metering bar are stupalith and make, have corrosion-resistant, high temperature resistant, the characteristic of long service life; The cylindrical of fule metering bar has groove, can carry out fine adjustment to the flow of filling pump, and simple in structure, and cost of production is low, stable performance.

Fig. 1 is an explosive view of the present utility model.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described.

As shown in Figure 1, the utility model comprises cylinder body 1, has ceramic core body 11 in the cylinder body 1, and the circumference of cylinder body 1 has liquid inlet port 12 and fluid mouth 13, and liquid inlet port 12 communicates with the inner chamber of ceramic core body 11 with fluid mouth 13 and be vertical mutually; Be inserted with fule metering bar 2 in the pottery core body 11, fule metering bar 2 cylindricals have groove 21, have retaining sleeve 22 on the fule metering bar 2, can adjust the state of fule metering bar 2 in ceramic core body 11 inner chambers by retaining sleeve 22, the flow of control ceramicpump; The end of cylinder body 1 has bottom 4, has mounting hole 41 on the cylindrical section of bottom 4, is convenient to the fixedly connected of filling pump, and bottom 4 is connected by seal ring 3 sealings and by nut 5 with cylinder body 1, prevents that liquid from leaking from the joint; Pottery core body 11 and fule metering bar 2 are made by ceramic material, and it is corrosion-resistant that filling pump is had, high temperature resistant, and the life-span is long, the characteristic of stable performance.

More than describing is to explanation of the present utility model, is not the qualification to model utility, and the utility model institute restricted portion within protection domain of the present utility model, can be done any type of modification referring to claim.
