Abstract
The utility model provides a novel anti-electrostatic pump cover and relates to the technical field of electric pumps, which comprises a metal pump cover. The metal pump cover is fixed to a plastic pump cover as a whole by means of a hexagon socket screw. The metal pump cover is provided with a groove. An O-shaped sealing ring is fixed onto the groove. The part of the metal pump cover, exposed out of a pump body, is connected with a wire. The wire is connected with the ground surface. According to the technical scheme of the utility model, not only the anti-electrostatic effect is realized, but also the static electricity generated during the system operation can be timely transmitted to the ground. Furthermore, the metal pump cover and the plastic pump cover are combined together, so that the production cost is lowered.
Description
Technical field
The utility model relates to electric pump technical field, is specifically related to a kind of antistatic pump cover.
Background technique
If the pump cover contact liq of existing common corrosion-resistant plastic pump part all serves as a contrast plastic material, the static that just there will be system running to accumulate cannot be derived by plastics, if may cause system equipment fault after accumulation a period of time, even damage, if and pump cover integral body adopts metal, cost is too high again.
Model utility content
The purpose of this utility model is to provide a kind of novel electrostatic prevention pump cover, it not only can antistatic, the static that can in time system running be produced transfers to the earth, and use the mode of metal pump cover and the combination of plastics pump cover to reduce cost of production, at metal pump, cover groove is set simultaneously, mounting O-shaped seal ring on groove, can prevent that the liquid being transferred from leaking from the gap between metal pump cover 1 and plastics pump cover 4.
In order to solve existing problem in background technique, the utility model is by the following technical solutions: it comprises metal pump cover 1, metal pump cover 1 is fixed together by hexagon socket head cap screw 2 and plastics pump cover 4, on described metal pump cover 1, be also provided with groove, on groove, be fixed with O RunddichtringO 3, metal pump cover 1 exposes pump housing part and is also connected with wire, and wire is connected with earth's surface.
The utility model it not only can antistatic, the static that can in time system running be produced transfer to the earth, and uses the mode of metal pump cover and the combination of plastics pump cover to reduce cost of production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of novel electrostatic prevention pump cover, it comprises metal pump cover 1, metal pump cover 1 is fixed together by hexagon socket head cap screw 2 and plastics pump cover 4, on described metal pump cover 1, be also provided with groove, on groove, be fixed with O RunddichtringO 3, O RunddichtringO 3 can prevent that the liquid being transferred from leaking from the gap between metal pump cover 1 and plastics pump cover 4, at metal pump cover 1, expose pump housing part in addition and be also connected with wire, and wire is connected with earth's surface, the static producing when system is moved like this will be transferred to the earth timely, so just do not have accumulation of static electricity, use the form of metal pump cover and the combination of plastics pump cover can guarantee that antistatic saved cost of production.
