The traditional way of water supply is inseparable from the storage tank. The water in the pool is usually supplied by the water supply company, so that the pressure water enters the pool and then becomes zero, resulting in a lot of energy wasted.

LOCKE series of non negative pressure and constant voltage frequency conversion water supply equipment, a set of water supply equipment which is directly connected to the tap water pipe network and does not produce any side effects on the tap water pipe network is developed on the basis of the frequency conversion water supply equipment based on the professional and technical personnel of , Germany LOCKE. Usually, she can replace the cistern, make full use of the pressure of tap water pipe network, directly supply water or relay water supply, avoid the two pollution and energy waste, save capital construction investment and shorten the construction period.

 

 

It is composed of the German LOCKE frequency conversion control cabinet, steady flow tank, water pump unit, instrument, valve, base and connecting pipeline, etc., which is suitable for water supply system with tap water pipe network and high water pressure and constant flow rate.

 

 

1., it is suitable for residential and commercial buildings, such as residential and fire water supply, various types of waterworks pressurized pumping stations, industrial production water, sewage treatment systems, agricultural sprinkler irrigation, drip irrigation and rural domestic water.

 

 

1. sections of capital and obvious energy saving

The effect of saving investment and saving energy is remarkable. In general, the use of VVVF equipment without negative pressure can save more than 50% of the cost of building the pool; it can save electricity by 10%~30% compared with other water supply equipment.

2. easy to install and manage

Can be equipped with horizontal steady flow tank, and can also be equipped with vertical steady flow tank. The two kinds of steady flow tanks have different characteristics: the horizontal steady current tank occupies small space, and the vertical steady current tank covers an area of small area. The manufacture and inspection of the steady flow tank comply with the regulations of GB150 steel pressure vessel. Because no compressed gas is stored in the steady flow tank, it is not required to be included in the management category of the pressure vessel.

3. simple and practical

It is designed for different application places and has good practicability.

4. function, safety guarantee

Advanced frequency conversion control technology has been adopted, which has the functions of overload, short circuit, overvoltage, undervoltage, lack of phase, overheating and soft start. When the equipment is closed, the signal alarm, self inspection, fault judgment and so on can be carried out in abnormal conditions, and the water flow can be automatically adjusted according to the water consumption.

5. advanced, reliable quality

Use of equipment accessories, screened many manufacturers, with reliable quality assurance, over-current components using SUS304 stainless steel products, even if the use of ordinary steel material of the wall also uses advanced "841 epoxy polyamide internal coating of food container preservation, in accordance with international standards of food hygiene; key parts and products the pump bearings, such as motor, frequency converter, circuit breaker, contactor, relay and small pressure tank is the internationally renowned brand;

6. configuration and originality

According to the difference between multi-storey buildings and high-rise buildings, the bypass or air pressure device can be configured to avoid frequent startup of pumps at low water supply at night, so as to extend the service life of the equipment, and its energy storage and voltage stabilizing performance is more significant.
