Description
Technical field
The utility model relates to a kind of part of pump, and more particularly, it relates to a kind of constant pressure frequency conversion water-feed one shell.
Background technology
Constant pressure frequency conversion feed feeder adopts Control Technique of Microcomputer, by microcomputer detected pressures sensor signal, according to pressure change and the working condition of water pump, automatically regulates the operation of multiple stage water pump, to reach this object of stable, reliable water supply.
And circuit board can be deposited in constant pressure frequency conversion water-feed, the normal work of constant pressure frequency conversion water-feed is controlled by circuit board, and circuit board is after long-term work, some electric elements on it can generate heat, especially capacitor, if cannot normally dispel the heat to capacitor, capacitor so will be caused overheated and cannot normally work, even there will be the phenomenon generation that capacitor burns.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of constant pressure frequency conversion water-feed one shell that can dispel the heat to capacitor.
For achieving the above object, the utility model provides following technical scheme: a kind of constant pressure frequency conversion water-feed one shell, comprise housing, described housing, one end of described housing is provided with fixed cap, ventilating water pipe and circuit board placed cavity is provided with in described housing, described ventilating water pipe and circuit board placed cavity mutually isolated, the inwall of described housing is provided with capacitor and places block, one end that the relative fixed cap of block placed by described capacitor be provided with respectively with circuit board placed cavity, the opening that ventilating water pipe communicates, described opening part is provided with the copper sheet be sealed and matched with it.
Preferably, one end of the relative housing of described opening be provided with around inner walls around convex tendon, described convex tendon is provided with sealing ring back to the side of opening, described sealing ring extends round the sidewall of convex tendon and forms a closed quadrangle, and described sealing ring and copper sheet are formed and be sealed and matched.
Preferably, the thickness of described copper sheet is 10mm.
Preferably, described copper sheet and capacitor are placed block and are removably connected by screw.
Compared with prior art, the beneficial effects of the utility model are: when constant pressure frequency conversion water-feed normally works, circuit board is fixed in circuit board placed cavity, capacitor on circuit board is attached on copper sheet, current flow through ventilating water pipe, due to the existence of copper sheet, ventilating water pipe and circuit board placed cavity are separated, thus ensure that current can not flow in circuit board placed cavity, effective protective circuit plate, and due to one end of copper sheet and capacitor contact, the other end and water stream contacts, therefore when current flow through ventilating water pipe, heat is delivered on copper sheet by capacitor, then heat is delivered in current by copper sheet again, thus reach to the left and right of capacitor heat radiation, effectively protect capacitor, capacitor is prevented to be burned, the useful life of the capacitor extended.

Embodiment
Referring to figs. 1 through Fig. 4, the utility model constant pressure frequency conversion water-feed one shell embodiment is described further.
A kind of constant pressure frequency conversion water-feed one shell, comprise housing 1, described housing 1, one end of described housing 1 is provided with fixed cap, ventilating water pipe 2 and circuit board placed cavity 3 is provided with in described housing 1, described ventilating water pipe 2 is mutually isolated with circuit board placed cavity 3, the inwall of described housing 1 is provided with capacitor and places block 4, one end that the relative fixed cap of block 4 placed by described capacitor is provided with the opening 41 communicated with circuit board placed cavity 3, ventilating water pipe 2 respectively, described opening 41 place is provided with the copper sheet 7 be sealed and matched with it, and the thickness of described copper sheet 7 is 10mm.。
When constant pressure frequency conversion water-feed normally works, circuit board is fixed in circuit board placed cavity 3, capacitor on circuit board is attached on copper sheet 7, current flow through ventilating water pipe 2, due to the existence of copper sheet 7, ventilating water pipe 2 and circuit board placed cavity 3 are separated, thus ensure that current can not flow in circuit board placed cavity 3, effective protective circuit plate, and due to one end of copper sheet 7 and capacitor contact, the other end and water stream contacts, therefore when current flow through ventilating water pipe 2, heat is delivered on copper sheet 7 by capacitor, then heat is delivered in current by copper sheet 7 again, thus reach to the left and right of capacitor heat radiation, effectively protect capacitor, capacitor is prevented to be burned, the useful life of the capacitor extended, and get the thick copper sheet of 10mm 7, can while guarantee copper sheet 7 intensity, the thermolysis to capacitor can be ensured again.
One end of the relative housing 1 of opening 41 is provided with the convex tendon 5 around housing 1 inner wall surrounding, described convex tendon 5 is provided with sealing ring 6 back to the side of opening 41, described sealing ring 6 extends round the sidewall of convex tendon 5 and forms a closed quadrangle, described sealing ring 6 is formed with copper sheet 7 and is sealed and matched, the setting of sealing ring 6, effectively strengthen the sealing between copper sheet 7 and convex tendon 5, anti-sealing drains in circuit board placed cavity 3.
Copper sheet 7 and capacitor are placed block 4 and are removably connected by screw 8, after copper sheet 7 for a long time use, its intensity and the capacity of heat transmission all can by impacts to a certain extent, conveniently carry out better to copper sheet 7, therefore adopt screw 8 that the capacitor of copper sheet 7 is placed block 4 to be fixed together, easy accessibility.
