Hot water pump

Introduction Model Description AT Representative (Tianjin Aote Pump Enterprise Standard) For example: AT250QJR100-20/1 250 indicates that the applicable hole diameter is not less than 250mm; AT stands for enterprise standard.

The parameter Q indicates diving (the initial letter of Pinyin); J indicates well use (the initial letter of Pinyin). R is hot water (the initial letter of Pinyin)

100 indicates that the flow rate is 100 m3/h; 20 indicates that the head is 20 meters; and /1 indicates that the first stage impeller is connected in series.

Introduction applies to enterprises and institutions such as: bath center, district heating, companies use geothermal energy to generate electricity, extract underground high-temperature hot water, according to different well diameters we have different specifications and models for users to choose. The device has low noise and high efficiency to save power.

Technical parameter 1: Permissible working water temperature range: +5 to +105°C

2: Solid impurity content (mass ratio) is not more than 0.01%

3: PH value (pH) 6.5-8.5

4: The content of hydrogen sulfide is not more than 1.5mg/L

5: Chloride ion content is not more than 400mg/L

6: The crew must completely invade the water. For vertical use, when selecting the model, the bore diameter should be matched with the model of the pump. Avoid large-diameter bores using small-diameter pumps. This is not conducive to heat dissipation of the motor.

Motor parameters Submersible motor lead length: 3m. If users need to extend the cable, they can call us in advance. The submersible motor is lubricated with clean water. Before the use, the motor chamber must be filled with clean water. (Note: Must be filled or it will reduce the service life of the motor.) If you forget to add the water motor, Burn out quickly.

Motor protection class: IPX8

Electromagnetic wire using high temperature waterproof line.

Power supply 380V, deviation does not exceed ± 5%, frequency 50HZ, deviation does not exceed ± 1%, if the customer needs special voltage or special frequency need to inform us in advance.

Material impeller: cast iron HT200, or tin bronze (various brands) such as: ZCuSn3Zn8Pb6Ni1 Pump casing: cast iron HT200, or stainless steel such as: 2Gr13.304 Pump Shaft: Cold drawn steel chrome plated, or stainless steel 2Gr13 (1050°C tempered, reinforced torque ) Motor seal: rubber seal O-ring; machine seal. Motor expansion regulator capsule rubber material.

Equipment Benefits Introduction --1: Careful assembly at the factory ensures quick and reliable installation on site - -2: Single stage impellers or multi-stage impellers in series with minimal noise. Good temperature resistance and long life.

--3: The unit can completely invade the water to avoid the disadvantages of the vacuum pump is easy to enter the air is not easy to use, supply hot water submersible pump unit (including the pump body and submersible motor consists of two parts), the outlet port matching flange, 12×60 bolts are 6 pieces. Or configure the corresponding water outlet (to facilitate the user to insert the hose installation), the use of maintenance instructions 1, 1 certificate of the packaging of a certificate, wooden packaging.

Exterior color:

Commonly used colors (when customers do not require): Duo Qinglan (chlorinated rubber paint) is suitable for spray coating in units that are not corrosive clean water.

Anti-corrosion coating If used in corrosive high temperature applications: The first can change the casting material such as stainless steel, bronze, etc. Second, if the corrosion is not particularly serious, the anti-corrosion coating epoxy top coat, brush anti-corrosion coating It can increase the service life of the unit.
