No Negative Pressure Frequency Conversion Horizontal Centrifugal Pump

No Negative Pressure Frequency Conversion Horizontal Centrifugal Pump

Description:

Model meaning:

Selection explain:

1. According to the actual engineering building door model, calculate the number of water and the largest water flow, general need supply pressure, flow rate shall be calculated by the institute of decision, such as design institute no arguments are given, the company will according to the actual situation, according to the < < building water drainage design specification GB50015 > > calculation income

2. Regulated storage tank should be rated pressure according to the actual engineering required pressure configuration, size selection may refer to relevant diaphragm type pressure tank selection mode.

3. Steady flow tank selection

Steady flow tank volume (V adjustable t) should be according to the water inflow and water yield change curve through calculation, sure, should press type calculation:

V adjustable t = train Q * train t

Type: V adjustable t --, steady flow compensator control volume (m3);

Train Q - design of water flow and water flow out of balance (m3 / h),

The equivalent of the size and the actual water supply number, water resources, local water habit, user properties and the other factors, such as season, general (forty - 300 households) take train Q = 2-4 m3 / h, (350-700 households) take train Q = 4 to 8 m3 / h, (700-1500 households) train Q = 8-16 m3 / h, and so on.

Train T - water peak pressure continuous wave time (h),

Generally take train T = 3-5 min, special circumstances should not be more than twenty min.

When the steady flow tank water into water shortage because of the low water level limit beyond jar, low water level alarm start, and automatically shut down equipment.

4. Such as system adopts stratified zone water supply mode, please let us know the specific division method and a few floor level.

5. Control system components points domestic and imported two kinds.

6. Equipment materials for meeting the requirement of food sanitation materials; If customers have special requirements, please directly give clear technical requirements, as the procurement contract attachment.

7. Schools, hotels and other consumption highly centralized place, should be based on the actual water point on how much the largest hours flow calculation.

8. In order to facilitate customer easy choice water supply equipment, our company made a reference number and flow and the corresponding steady flow tank configuration corresponding selection table, as a summary on the selection of parameter table, the table can according to the customer to provide the number of users, and pick a non-negative pressure method of water supply equipment corresponding flow rate and the number of pump and the recommended steady flow tank model, and then according to the building floor height to calculate the water supply equipment required lift, then choose relevant pump factory corresponding model of the customer, can complete set no negative pressu

Selection of the parameter list (1) (for reference only):

Equipment installation size:

Zhejiang fuyang BOjin machinery manufacturing co., LTD. Is a complete set of no negative pressure water supply equipment and constant pressure frequency conversion water supply equipment no negative pressure steady flow and form a complete set of stainless steel tank and complete line of design, manufacture, and installation of professional equipment manufacturers, high-tech enterprises, with a number of independent research and development patent, self-support right of import and export.

Companies with complete sets of water supply equipment with stainless steel without negative pressure steady flow and complete line of production for the water industry at home and abroad, is the domestic no negative pressure and constant pressure frequency conversion water supply equipment design, production and installation of the integration of the country's largest production base of OEM manufacturers.

BOJIN machinery does not forget to accumulate in the high speed development, by product, talent, management, channel development and innovation, from a single competition, transition for the scale of the multi-line competition and resources reserves.

In 2012, the Po into the water supply in "self accumulation and self development" concept, under the guide of eclecticism, from once OEM OEM production for someone else to have independent intellectual property rights BOJIN series: no negative pressure overlying water supply equipment, constant pressure frequency conversion water supply equipment, modular stainless steel water tank series, box-type overlying water supply equipment, automatic sewage equipment such as complete sets of water supply equipment, "self development, self accumulation" makes the Po into the water swelling, laid a solid foundation for the competition with the domestic first-class brand.

Launched into water grand blueprint, there will be more sophisticated products, more convenient operation, more environmental protection, longer service life, more competitive and efficient services, more comprehensive range of support, and the goal of "to create the first-class in China famous brand" of mind, along the way forward to harvest.

We always adhere to two big commitment,

Delivery time commitment -- -- -- -- -- - we are committed to: according to the regulation time, complete the order with good quality

Service commitment -- -- -- -- -- -- -- -- - we are committed to: pre-sale, sale and after-sale, nowhere is not in service, we sincerely provide you with timely and satisfactory service.

In order to improve the technology of product research and development ability, we established the provincial enterprise technology center,
