Wall-mounted furnace canner motor pump with automatic exhaust device

Abstract

The invention discloses a wall-mounted furnace canner motor pump with an automatic exhaust device. A valve seat in the automatic exhaust device in the motor pump is provided with an exhaust opening and is arranged on a support; a valve body is fixed in the valve seat and is provided with a valve body hole, and the valve body hole is communicated with the exhaust opening on the valve seat; a valve plug seals the valve body hole through a sealing gasket and is connected with the valve body through a spring; a movable block is provided with a pull rod; the pull rod is arranged on the support, can move up and down along the support and meanwhile forms a gas cavity in the valve seat while moving; the movable block pulls the valve plug through the pull rod on the movable block; a knob is arranged on the exhaust opening on the valve seat; and the knob is provided with a knob exhaust opening and is communicated with the exhaust opening of the valve seat through a gap between the knob and the valve seat. The invention solves the problems that the motor pump needs to manually exhaust in the working process, is inconvenient to operate, and the manual exhaust is difficult to control water leakage in the motor pump to damage other electrical appliances to cause safety and environmental pollution, and performs the action of safety, convenience and environmental protection.

Description

Technical field: [0001] The invention relates to a shielded pump, in particular to a shielded electric pump for a wall-hung boiler with an automatic exhaust device. Background technique: [0002] The canned pump is a centrifugal pump, and its working principle is: relying on the high-speed rotating impeller, the liquid obtains energy under the action of inertial centrifugal force to increase the pressure. The characteristic is that the motor and the pump adopt an integrated structure, all of which are statically sealed, so that the electric pump is completely leak-free; the fully-closed, leak-free structure can transport toxic and harmful liquid substances; the shielded water-cooled motor and the cancellation of the cooling fan make the pump low-noise Silent operation, suitable for occasions with high environmental noise requirements; graphite sliding bearings lubricated by the transmission medium make the operation noise lower and do not require manual oiling, reducing main...

AI Technical Summary

Problems solved by technology

[0005] The invention aims at the existing shielded electric pump for wall-hung boilers, which needs to manually discharge the gas in the pipeline and the gas inside the electric pump during the working process. The existing operation is inconvenient and it is difficult to control the leakage of water in the electric pump, and it is easy to damage other electrical appliances, causing safety and environmental problems. pollution problem, and provide a canned electric pump for wall-hung boilers with an automatic exhaust device, which can effectively solve the problems existing in the existing canned electric pumps for wall-hung boilers
