QHYB-CDL frequency conversion constant pressure water supply equipment (equipped with CDLF stainless steel multi-stage centrifugal pump) is a new type of water supply equipment without tower. It is composed of three parts: the control unit of the pump unit and the pressure stabilizing device. Water supply capacity is determined by the water pump system, coordinated operation is controlled by a control system, the main function of pressure stabilizing device is storage pressure, a small amount of water and cope with normal pipeline leakage, but also a indispensable part of automatic control. When a large number of water, pipe network pressure drop, the pump automatically start the water supply.
QHYB-CDL frequency conversion constant pressure water supply equipment (equipped with CDLF stainless steel multi-stage centrifugal pump) can be divided into air pressure water supply equipment and variable frequency water supply equipment according to different working modes. Widely used in life, fire, production, spray until a variety of fields.
The water pump is the foundation of water supply equipment, water supply equipment is the fundamental guarantee to show its ability of water supply, water supply equipment for matching pumps are general and can be a variety of program flow, Yang appropriate pump. 1~4 or more of the parallel operation of the pump according to the flow, the program needs Yang products, with the addition of a booster pump pressure regulated power supply equipment (water flow pump group) as in the small flow range and the main pump switching operation, to further reduce the energy efficiency.
According to the work of the equipment can be divided into different types of life, fire, sprinkler type and the common model of life fire.
Select a set of automatic water supply equipment is based on the basic design of the water supply and water supply pressure (water head), in addition to taking into account the use of the type of flow changes.
Continuous type: a day when there is little flow of zero, or the normal leakage of the pipe network to maintain a certain flow, for example, large hotels, hotels, industrial and mining enterprises, such as pressure system.
Intermittent type: water trough time is long and the flow is very small or zero, for example: small office buildings, office buildings, commercial buildings, various types of residential, and production of water, etc.
At the same time, we should also consider the changes in the flow of water in a certain period of time, as well as changes in different seasons, different areas of water use and other factors.
The fire sprinkler water supply equipment generally should choose the pneumatic water supply equipment, because of its long term in the system pressure, changes the flow, leakage of pneumatic water supply equipment can meet the general tube, and increase the auxiliary pump a small flow, usually without starting the main pump, energy saving.
The advantages of variable frequency water supply equipment: constant pressure water supply and constant pressure value in a certain range can adjust the voltage accuracy is generally less than 0.02MPa, variable frequency speed control is an efficient method of energy saving energy saving average 20%, compared with the usual pressure water supply equipment in addition, variable frequency starting of impulse current and pump cover impact is small, at low speed running noise.
The advantages of pneumatic water supply equipment: relatively low cost, simple control system technology, convenient service, easy maintenance.
