Description
Technical Field
The utility model relates to a pump technical field, concretely relates to diaphragm constant pressure pump.
Background
Diaphragm pumps, also known as control pumps, are the main type of actuator that is operated by power to vary the fluid flow by receiving a control signal from a regulating control unit. The diaphragm pump is used in the control process to receive the control signal of the regulator or the computer and change the flow rate of the regulated medium to maintain the regulated parameters in the required range, so as to realize the automation of the production process. If the automatic adjustment system is compared to a manual adjustment process, the detection unit is the human eye and the adjustment control unit is the human brain, the execution units, the membrane pumps, are the human hand and foot.
At present, common water purifiers in the market are divided into a pipe pressure type (a water source is municipal tap water) and a self-suction type (no water inlet pressure or small water inlet pressure). The pipe pressure type water purifier is mostly used in places with municipal tap water in cities, while the self-absorption type water purifier is mostly used in rural areas, especially in backward areas without tap water in mountainous areas, or the requirement that the water pressure of the municipal tap water cannot be met due to poor tap water conditions. And as logistics develops, both models can be applied in opposite scenes by channel conflict. However, when the pipe-press type water purifier is used in areas without tap water or with low water pressure, water cannot be produced or the water production amount is seriously insufficient. When the self-priming water purifier is used under a municipal tap water source, the working pressure of the water purifier is ultrahigh, the water leakage of the whole water purifier is possibly bad, and the service life of an RO (reverse osmosis) membrane is influenced.
In most domestic buildings, secondary water supply is provided, water tanks are arranged on the floors, and water pipes are connected to each house at every moment, so that the difference of water pressure of different floors of the same building is large, and the phenomenon that the water purifier is used on different floors can cause the difference of water inlet pressure of the water purifier to be large, the pressure of the higher floor is insufficient, and the pressure of the lower floor is higher. And then make the water purifier when higher floor during operation, the flow is not enough, and system water inefficiency and power consumptive, and lower floor uses the water purifier can lead to operating pressure to be on the high side, influences water purifier life, and more serious probably leads to the too high bad phenomenon of leaking of complete machine pressure appearance.
