Description
Technical field
The utility model relates to a kind of patch bay, particularly a kind of high-pressure masked pump patch bay.
Background technology
At present; canned pump pumped (conveying) medium need gap between stator can and rotor shielding sleeve; when bearing inordinate wear, stator can and rotor shielding sleeve will produce friction, if stator can mill leaks; pumped (conveying) medium will enter in bore of stator; so when system pressure is very high, the bearing capacity of stator cage and patch bay must be considered, carry out second protection; ensure that high-pressure medium can not leak into outside casing, in order to avoid the personnel that cause injure.Existing canned pump wiring rack structure puts into binding post in the installing hole of terminal block; with insulating powder by being cast into an entirety; terminal block and insulating powder and the combination between binding post and insulating powder are not very strong; this patch bay sealing property is bad; bear pressure low, be used on high-pressure masked pump and do not have second protection effect.
Summary of the invention
The utility model is for the proposition of above problem, and a kind of high-pressure masked pump patch bay of research and design, in order to solve existing high-pressure masked pump, patch bay sealing property is bad, bears the shortcoming that pressure is low.The technological means that the utility model adopts is as follows:
A kind of high-pressure masked pump patch bay, comprising: terminal block, binding post, insulated column and insulating case, the installing hole that described terminal block has, one end is bellmouth one, remainder is screwed hole, described insulated column one end outer wall has the taper surface one that same bellmouth one mates mutually, and corresponding inwall has the identical bellmouth two of same outer wall taper surface one tapering, outer wall remainder has the external screw thread one of same screwed hole coupling, inside has the cylinder type hollow that same binding post cylinder-shaped body matches, in the screwed hole that insulated column is screwed into terminal block until taper surface together bellmouth one contact fixing, described binding post one end outer wall has the taper surface two that same bellmouth two coordinates, binding post injects in insulated column until bellmouth two and taper surface two coordinate fixing, the external screw thread two that other end binding post end has has been threaded nut, insulated column outer cover away from bellmouth one side is provided with insulating case, and insulating case is higher than insulated column after installing, after the nut inwardly tightened, make binding post and insulated column spacing fixing.
Before being screwed into the installing hole of terminal block as preferred described insulated column, outer surface scribbles epoxy resin.
Be hex nut as preferred described nut, and nut is provided with plain cushion and spring washer with pad between insulating case top.
Compared with the prior art, high-pressure masked pump patch bay described in the utility model, terminal block, combination between binding post and insulated column are fixed, all coordinated by the identical conical surface of tapering and taper hole, good seal, because insulating case exceeds insulated column, so can by tightening hex nut, ensure that the conical surface seal between binding post and insulated column and the conical surface seal between insulated column and terminal block, epoxy resin can improve initial sealing effect further and play reinforcement effect.
High-pressure masked pump described in the utility model is owing to have employed the conical surface as sealing surface, and when chamber pressure increases, the power acted on taper surface increases, and sealing thrust increases, and sealing effectiveness is better, makes patch bay have high load performance.

Embodiment
As Figure 1-5, a kind of high-pressure masked pump patch bay, comprising: terminal block 1, binding post 2, insulated column 3 and insulating case 4; The installing hole that described terminal block 1 has, one end is bellmouth 1, remainder is screwed hole 12, described installing hole and supporting binding post 2, insulated column 3 and insulating case 4 are preferably 3-7 group according to the kind of wiring and quantitative requirement, wherein installing hole described in the present embodiment is evenly provided with three in terminal block 1 center, and the circle that the center of three installing holes is linked to be is concentric circles with circular terminal block 1, binding post 2, insulated column 3 and insulating case 4 correspondence of installing is coordinated to be provided with three groups (as shown in Figure 1) with three installing holes.
Described insulated column 3 one end outer wall has the taper surface 1 (namely bellmouth 1 is identical with the tapering of taper surface 1) that same bellmouth 1 mates mutually, and corresponding inwall has the identical bellmouth 2 32 of same outer wall taper surface 1 tapering, outer wall remainder has the external screw thread 1 of same screwed hole 12 coupling, inside has the cylinder type hollow 34 that same binding post 2 cylinder-shaped body matches, the screwed hole 12 that insulated column 3 is screwed into terminal block 1 is interior until taper surface 1 contacts fixing with bellmouth 1, before described insulated column 3 is screwed into the installing hole of terminal block 1, outer surface scribbles epoxy resin, seal and reinforcement effect (as shown in Figure 5) terminal block 1 and playing of insulated column 4.
Described binding post 2 one end outer wall has the taper surface 2 21 that same bellmouth 2 32 coordinates, binding post 2 injects in insulated column 3 until bellmouth 2 32 and taper surface 2 21 coordinate fixing, the external screw thread 2 22 that other end binding post 2 end has has been threaded nut 6 (as shown in Figure 3), insulated column 3 outer cover away from bellmouth 1 side is provided with insulating case 4, and insulating case 4 is higher than insulated column 3 after installing, after the nut 6 inwardly tightened, make binding post 2 and insulated column 3 spacing fixing, because insulating case 4 exceeds insulated column 3, so can fastening nut 6 be passed through, ensure that the conical surface seal between binding post 2 and insulated column 3 and the conical surface seal between insulated column 4 and terminal block 1, described nut 6 is hex nut, and nut 6 is provided with plain cushion 7 and spring washer 5 with pad between insulating case 4 top, plain cushion 7 pads at insulating case 4 top, spring washer 5 is located between nut 6 and plain cushion 7, spring washer 5 is used for the outside pretightning force of 6 one, nut, increase the frictional force with binding post 2, avoid coming off of nut 6.
Taper surface 2 21 after installing on binding post 2 and insulated column 3 and taper surface 1 are positioned on terminal block 1 and have bellmouth 1 side (as shown in Figure 2), when high-pressure masked pump stator can leaks extremely, the high-pressure medium of conveying will enter in bore of stator, act on binding post 2, the pressure of insulated column 3 end will increase, the power acting on taper surface increases, sealing thrust increases, and sealing effectiveness is better, thus ensures that patch bay has high load performance.
High-pressure masked pump good seal performance described in the utility model, bears pressure high, when stator can inordinate wear is leaked, can carry out second protection for high-pressure masked pump, ensures that high-pressure medium can not leak into outside.
The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and inventive concept thereof and replace or change, all should be encompassed within protection range of the present utility model.
