Abstract
The utility model relates to a copper pump plunger preventing a crank case from carrying liquid. The copper pump plunger preventing the crank case from carrying the liquid aims to solve the problems that after copper liquid of an existing copper pump leaks, the copper liquid moves axially along a plunger and a middle connection rod and causes blockage of an oil way after entering the crank case, the phenomenon that a bearing pad and a crosshead are corroded often occurs, a bearing is fast to wear, and the running period is short. The copper pump plunger preventing the crank case from carrying the liquid comprises a plunger body (1). The plunger body (1) is connected with a packing gland (2) and the middle connection rod (3). A threaded opening, connected with the middle connection rod, of the plunger body is provided with a blocking piece (4), and the blocking piece is fixed through a back cap (5). The outer diameter of the back cap is smaller than that of the plunger body. As an auxiliary facility of a copper pump, the copper pump plunger preventing the crank case from carrying the liquid has the advantages that the phenomenon that machine oil of the crank case of the copper pump needs to be replaced due to liquid carrying can be avoided, and the phenomenon the bearing pad and the crosshead are corroded due to liquid carrying can be avoided.
Description
Technical field
The utility model relates to a kind of accessory of copper pump, is specifically related to a kind of crankcase that prevents with the copper pump plunger of liquid phenomenon.
Background technique
The copper pump is used for carrying copper liquid.Because there is defective in the sealability of this pump filler and outside framework oil seal, causes crankcase often to be with liquid, makes the equipment operation cycle shorter, brings major hidden danger to safety in production.For this reason, when overhaul, need to improve the copper pump.This pump is to be driven by crankshaft ﹠ connecting, changes over linear reciprocating motion by crosshead, is carried out successively imbibition and is beaten liquid by 3 plungers.As shown in Figure 1: cylinder portion tetrafluoro packing seal, crankcase is partly used skeleton oil seal.Because the copper liquid osmotic force that this pump is carried is strong, corrosivity is strong, discharge opeing pressure is high, causes the tetrafluoro Reliability of Packing Seal to reduce.Do axial motion along plunger and middle brace rod after the copper liquid seepage, a part is blocked by outside framework oil seal, flows into body in the copper pump, flows into mother liquor tank by liquid return hole, and another part enters crankcase by outside framework oil seal.Because this crankshaft ﹠ connecting adopts splash system lubrication, after copper liquid enters crankcase, cause oil circuit to stop up, tile kilning often occurs and burn the crosshead phenomenon, bearing wear is fast, and service cycle is shorter.
The model utility content
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of crankcase that prevents with the copper pump plunger of liquid phenomenon, so that the crankcase of copper pump can again because of band fluid exchange machinery oil, yet can not cause tile kilning and burn the crosshead phenomenon because of band liquid.Reduce maintenance expenses, reduce and shut down number of times, guarantee the service cycle of equipment, for safety in production creates conditions, also bring certain economic benefit for enterprise.
Above-mentioned purpose is achieved through the following technical solutions:
Prevent that crankcase is with the copper pump plunger of liquid phenomenon, comprise plunger body, described plunger body bonding pad gland and middle brace rod, the silk that described plunger body is connected with the middle brace rod mouthful upper catch of installing, described catch is fixed by back of the body cap, and the external diameter of described back of the body cap is less than the external diameter of described plunger body.
The described crankcase that prevents is with the copper pump plunger of liquid phenomenon, and described catch adopts ring.
The described crankcase that prevents is with the copper pump plunger of liquid phenomenon, and the described Gland of described catch distance is not less than 3mm.
The described crankcase that prevents is with the copper pump plunger of liquid phenomenon, and the external diameter of described catch is greater than the external diameter of described Gland.
Beneficial effect:
The utility model adds a catch in the middle of copper pump plunger and middle brace rod, even can not enter crankcase by outside framework oil seal along plunger and middle brace rod after the copper liquid seepage yet, but directly the copper liquid of seepage is kept off into middle body by catch, flow into mother liquor tank by liquid return pipe, so both guaranteed that copper liquid did not enter crankcase, and can guarantee again not waste copper liquid.Can again because of band fluid exchange machinery oil, yet can not cause tile kilning and burn the crosshead phenomenon because of band liquid.Reduce maintenance expenses, reduced the shutdown number of times, guaranteed the service cycle of equipment, created condition for the safety in production of full factory, also brought certain economic benefit for enterprise.
Description of drawings
Fig. 1 is structural representation of the present utility model,
Reference numerals list: 1-plunger body, 2-Gland, 3-middle brace rod, 4-catch, 5-back of the body cap.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.
Embodiment 1:
Fig. 1 is structural representation of the present utility model, as we can see from the figure, the crankcase that prevents of the present utility model is with the copper pump plunger of liquid phenomenon, comprise plunger body 1, described plunger body bonding pad gland 2 and middle brace rod 3, the silk that described plunger body is connected with the middle brace rod mouthful upper catch 4 of installing, described catch is fixing by back of the body cap 5, and the external diameter of described back of the body cap is less than the external diameter of described plunger body.Can not enter crankcase by outside framework oil seal along plunger and middle brace rod after the copper liquid seepage of the present utility model yet, but directly the copper liquid of seepage be kept off into middle body by catch, flow into mother liquor tank by liquid return pipe.
Embodiment 2:
Present embodiment and embodiment's 1 difference is: described catch adopts ring.The catch of ring is in order 360 ° to block in all directions the copper liquid after the seepage, better protecting effect.
Embodiment 3:
Present embodiment and embodiment 1 or embodiment's 2 difference is that the described Gland of described catch distance is not less than 3mm.For guarantee to drive rear catch and Gland do not produce bump, every plunger jiggering catch and Gland end face (filler is normal compress after) behind the upper time point have the gap of 3mm, if the gap less than 3mm, machining middle brace rod internal thread end face is adjusted.
Embodiment 4:
The difference of present embodiment and above-described embodiment is the external diameter of described catch greater than the external diameter of described Gland, further strengthens the occlusion effect to seepage copper liquid.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises the technological scheme that is comprised of above technical characteristics combination in any.Unaccomplished matter of the present utility model belongs to those skilled in the art's common practise.
