Problems solved by technology

[0002] The high-pressure clean water pump is one of the main equipment of the three-pipe high-spray. It mainly produces high-pressure water jets, requiring the pump pressure to be greater than 30MPa and the flow rate to be greater than 70L / min. The system and the pump body are composed of the following problems during use: when the liquid level in the pool is too low, air will be mixed into the inlet of the high-pressure pump, causing the high-pressure pump to be empty, making the high-pressure pump unable to operate normally

Embodiment Construction

[0011] Embodiments of the present invention are further described below in conjunction with accompanying drawings:

[0012] Such as figure 1 As shown, the high-pressure clean water pump exhaust system includes a high-pressure pump 3, and the high-pressure pump 3 is connected to the pool 1 through a pneumatic switch valve 5; the high-pressure pump 3 is driven by a motor, and its outlet pipeline 6 is connected with a branch pipe 7, The branch pipe 7 is connected to the DN15 exhaust valve 4; the bottom of the pool 1 is provided with a liquid level transmitter 2. Wherein, the pneumatic switching valve 5, the motor and the liquid level transmitter 2 are respectively electrically connected to the PLC.

[0013] The working process is as follows: open the pneumatic switching valve 5, and the water in the pool 1 is transported to the required place through the high-pressure pump 3. When the water level in the pool 1 is too low, air is mixed into the water inlet pipe, causing the gas t...

Abstract

The invention relates to fluid conveying machinery, in particular to a high-pressure clean water pump exhaust system. The high-pressure clean water pump exhaust system includes a high-pressure pump, which is connected to the pool through a pneumatic switch valve; the high-pressure pump is driven by a motor, and a branch pipe is connected to the outlet pipeline, and the branch pipe is connected to a DN15 exhaust valve; There is a level transmitter. Among them, the pneumatic switch valve, the motor and the liquid level transmitter are respectively electrically connected with the PLC. The invention solves the problem of emptying of the high-pressure pump in the prior art, has the characteristics of energy saving and environmental protection, low maintenance cost, and timely exhaust, and ensures the normal operation of the equipment by timely discharging the gas in the pipeline.

Description

technical field [0001] The invention relates to fluid conveying machinery, in particular to a high-pressure clean water pump exhaust system. Background technique [0002] The high-pressure clean water pump is one of the main equipment of the three-pipe high-spray. It mainly produces high-pressure water jets, requiring the pump pressure to be greater than 30MPa and the flow rate to be greater than 70L / min. The system and the pump body are composed of the following problems during use: when the liquid level in the pool is too low, air will be mixed into the inlet of the high-pressure pump, causing the high-pressure pump to empty, making the high-pressure pump unable to operate normally. Contents of the invention [0003] The object of the present invention is to provide an energy-saving and environment-friendly high-pressure clean water pump exhaust system with low maintenance cost and timely exhaust. [0004] The high-pressure clean water pump exhaust system of the present...
