The present invention has the controller set inside the pump body integrally for convenient installation and use, can start and stop automatically based on the liquid level and can shut off automatically in case of fault or overheat motor. The present invention has automatic control and high safety and reliability.
Description
Technical field
The present invention relates to Submerged Motor Pumps, belong to the pump machines equipment technical field.
Background technique
Proof submersible sand discharging pump is widely used in occasions such as building site, hospital, municipal administration, traffic, residential quarters, hotel and carries out blowdown, sewage treatment etc.At present, the proof submersible sand discharging pump that draining is used has a dual mode in control: a kind of is to adopt manual monitoring, opens and stop the running of submersible pump according to the height of water level by the special messenger, and deficiency is to need the special messenger to nurse, and automaticity is not high, uses inconvenience; Another kind is the start and stop of adopting external electric control box control pump, and electric control element adopts electromagnetism contact control element more in this mode, complex structure, and the life-span is short, poor reliability, rate of fault height; And electric control box separates with the pump housing, and installation, transportation and use are all inconvenient, need take certain space during installation.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of easy to use, integrated automatic mining explosion-proof submersible sand discharging pump that automaticity is high is provided.When liquid reaches high water level and is provided with, start operation automatically; When liquid reaches low water level and is provided with, out of service automatically; When fault takes place, out of service automatically.
The present invention adopts following technical solution:
Integrated automatic mining explosion-proof submersible sand discharging pump comprises loam cake, wiring casing, motor, control housing, pump cover, the pump housing and pump seat from top to bottom successively, and each several part links together, and the joint is equipped with seal ring; In the wiring casing control box is installed, is provided with non-contact power switch in the control box, power line is electrically connected with motor by non-contact power switch; Be provided with thermosensitive element in the motor, motor shaft is an axis; Be provided with switch and profit probe in the control housing; Be provided with impeller in the pump housing, impeller is installed in the motor shaft lower end of motor, respectively is provided with a mechanical seal in the top and bottom of pump cover on the motor shaft, is provided with seal ring between the water intake of impeller and pump seat, in the grease chamber of pump cover lubricant oil is housed; Thermosensitive element, switch and profit probe all are electrically connected with non-contact power switch; In addition, also be provided with high-order liquid level sensor and the low level liquid level sensor that is electrically connected with non-contact power switch.
The present invention is installed in control gear in the pump housing, becomes an organic whole, has made things convenient for to install and use.And can realize automatic control, when liquid level rises to a high position and is provided with, start automatically; When liquid level drops to low level and is provided with, autostop; Automatically shut down when when parts such as bearing, mechanical seal break down or be long, asking that overload operation causes motor overheating.Automaticity and safety reliability have been improved.
