4~30KW Corrosion resistant pump / PWF stainless steel sewage pump

4~30KW Corrosion resistant pump / PWF stainless steel sewage pump

PW horizontal sewage pump Scope:

1. PW horizontal sewage pump can transport sewage, containing suspended solids, long fiber material and domestic wastewater. The pump body is of high quality cast iron material, the medium temperature does not exceed 100 ℃.
2. PWF stainless steel sewage pump can be transported with acidic, alkaline or other corrosive sewage, widely used in chemical, petroleum, light industry, food, pharmaceutical, brewing, environmental protection and sewage treatment industries. The pump body and the overcurrent part are made of 304 stainless steel, the medium temperature is not higher than 100 ℃.

PW type horizontal sewage pump start, stop and run:

1. start

• Check whether the bearing tank has been refueled, the oil level is normal oil level line.
• Check that the direction of rotation of the motor is the same as the direction of rotation of the pump.
• Close the outlet valve and pressure gauge cocks, while the upper part of the pump screw hole, to the pump suction pipe irrigation.
• Start the motor and open the pressure gauge cock.
• to be the normal speed of the pump to work, the pressure gauge shows the corresponding pressure, open the vacuum table cocks and gradually open the drain line on the valve to the needs of so far.stop

2. Stop

• Slowly close the outlet pipe valve, and then cut off the power.
• In case of frozen season, after the shutdown, open the lower part of the pump body of the four plugs, venting water, so as not to crack.
• If the long term do not, then the parts should be opened to wipe, and in the sliding surface coated with anti-rust oil, proper preservation.

3. Running

• During the operation of the pump, we must pay attention to observe the instrument, bearing heat, filler leakage and pump vibration, noise, etc. are normal, such as abnormalities should be promptly treated.
• bearing the maximum temperature shall not exceed 75 ℃.
• bearing oil should be maintained in the normal oil level line, not too high or too low, too low should be timely refueling.
• seal ring and impeller with the gap, greater than the following specified value should be replaced when the new seal ring.

When the diameter of the suction nozzle is less than or equal to 100mm, the total clearance in the diameter direction is ≥1.5mm

When the diameter of the suction port is> 100mm, the total diameter of the diameter is ≥2mm
