ZWL 01
The conventional mode of water supply can not be without a water storage pool,the water therein is usually supplied by a tap water pipe network, in this way the pres-sured water becomes non-pressure when going into the pool, causing a lot of energy wasted.
ZWL micro-computerized non-suction pressure constant-flow water supply equipment is completed one capable of directly connecting with the water pipe netork, producing no side effect to the network, replacing the impounded re-servoir,directly supplying water or by way of relay by fully using the pressure of the network avoiding secondary po-
llution and energy waste greatly saving the construction investment and shortening the construction phase. The e-quipment consists of a converter control cabinet, a flow stabilizing tank, the pump unit, meters, valve pipeline unit etc.and issuitable for the water supply system of a tap water pipe network ans required to boost the water pressure and make the flow constant.

1. No need of water pool, saving both fund and energy
ZWL micro-computerized non-suction pressure cons- tant-flow water supply equipment is of a notable effect on both fund and energy saving,which, compared to others,can be over 50% for the pool construction cost and 2040%for electricity saving.
2.Simple installation and less land used
I t can be equipped with either a horizontal or a ver-tical flow stabilizing tank.the two tanks are of different Features:less space for the horizontal one and less land for the vertical one.the design,manufacture and inspection of
the flow stabilizing tanks made in this Co.conform with the provisions in GB150steel made pressure containers ,but inside of them no compressed air is stored, unnecessary to be listed in the management scope of pressure containers.3.Extensive purposes and strong suitability
I t can be used for either living or fire-fighting water supply and equpped with water pumps of any models.when used for fire-fighting water supply, it has to be equipped with the water pump specially for fire-fighting. CHARACTERISTIC
4.Full functions and high degree of intelligence
I t uses the advanced know-how of convertre control,

starting etc,functions and can do signal warn,self-detection and failure judgment and auto matically adjust the water supply flow upon the watre quantity being used.
5.Advanced product and reliable quality
the accessories used with ZWL series equipment have been screened among many manufacturers and therefore hold a reliable quality. The main overflow parts are made of sus304 stainless steel and,eveen the flow stabilizing tank made of common carbon steel,its internal wall is also co-ated with the advanced 841 epoxy polyamide cating for the internal wall of food containers for anticorrosion.the products conform with the provisions in living and drin-king water sanitation supervising & managing method and the key parts inside of the products,relay and miniature pneumatic tank, are those of the world and domestic well-known brands.
6.Personalized design,showing a distinctive style
Upon the features of multi-floor buildings,ZWLseries equipment is equipped with a by-pass pipe (omissible for multiple pump units) and aminiature pneumatic tank. When the pressure of the tap water pipe nework can meet with the water used demand, the system supplies water directly through the by-pass pipe and, in the pump switchover proc-ess, the pmeumatic tank acts as constant-pressure.

Once the equipment is put into use, the water from the tap water pipe network goes into the flow-stabilizing tank,the air inside of the tank is exhausted from the vacuum remover, which will automatically close after being full of water. The system supplies water to the water pipe network directly through the by-pass pipe when the net-work
s pressure and flow satisfies the demand of use and,
while not, the pressure signal of the system is feedback to the converter controller via the remote pressure gauge, the water pump starts running and automatically adjusts the rotating speed upon the water quantity being used to get to constant-pressure water supply . I f the running pump gets to the power frequency rotating speed, then another one starts converter running.when the pump supplies water, the system forms relayed water supply if the supplied water quantity from the tap water pipe network is more than the pump
s flow; at the peak use of water,when the said
quantity is lower than the said flow,water supply can be still normal with the water inside of the flow stabilizing tank as a supplementing water source. At this time,air goes into the tank via the vacuum remover to have the vacuum destroyed to make sure of non-suction pressure formed with the network; after the peak use of water, the system resets to the status of relayed water supply. When the net-work stops supply to cause the level inside of the tank continually lowering,the level detector feedbacks the signal to the converter controller and the pump automatically stops to protect the pump unit.

2.Do not let the water pump run for a long time with the outlet valve fully closed and at the hump of the perfor- mance curve, still more,run idle.10-20drops/min leak is allowed for the root-twisted seal,used as the shaft seal, and 2-3 drops/min leak for the mechanical one.
3.The bearing s temperature at runing should not be over 75
.
4.Lubricate bearings once every 500h of wate pumps run-ning.
5.Necessary measures have to be taken in case of a long- time stop of the equipment to prevent it from getting dirty and rusted, plus warming and anti-freezing ones if in winter.
6.Carry out a periodic sewage drainage upon the water nature for the equipment under running.
