Description

Technical Field

[0001] This utility model relates to the field of sewage drainage technology, and more specifically, to a starting device for a negative pressure drainage system. Background Technology

[0002] Negative pressure drainage systems rely on negative pressure to pump sewage from residential courtyards through pipes to end-point sewage treatment plants or municipal pipe networks for treatment. During sewage transmission, the pipes in a negative pressure drainage system contain little or no air, essentially operating at full capacity; it can also be called a "single-phase flow negative pressure drainage system." Typically, a starting device powers the entire system, including a control motor and a drainage pump. For example, the automatic vacuum negative pressure drainage system disclosed in patent CN214661126U requires connecting a power source and the air source control valve to the desired product (vacuum suction cup, pneumatic clamp, etc.). Clicking the start button activates the machine, and the control motor begins running, inputting negative pressure into the negative pressure storage tank through the vacuum input pipe. Simultaneously, the PLC negative pressure display monitor detects and displays the current machine negative pressure via the negative pressure control pipe. Once the negative pressure stabilizes, the machine is ready for use. To stop use, simply click the off button. Before operation, the negative pressure air tank and the negative pressure water tank are connected by a pressure interconnection hose, so the negative pressure of the negative pressure air tank and the negative pressure water tank is interconnected. When the machine is in use, after a certain amount of water is sucked in, the machine will automatically alarm and drain water by sensing the water level through the water level sensor. Then the alarm will flash and sound to indicate.

[0003] When the above-mentioned device is in use, it is inconvenient to disassemble the control motor if it is damaged, which affects the working efficiency of the control motor. At the same time, the existing control motor is connected to the pump head, and when it malfunctions, it needs to be completely disassembled, which is inconvenient for maintenance.
