In life, we often encounter questions and problems, and at this time, if we can't solve them ourselves, we should start to find ways to seek help to solve them. I believe you have been wondering about Willard pump for a long time. In fact, Willard pump is a very famous product. Knowing more about Willard pump is also very helpful to our life. Next, let's get to know each other through Bian Xiao's introduction. So, what about Willard pump?

Structure Description of Le Wei Water Pump

1, R-type hot water circulating pump is a single-stage single-suction cantilever type, with horizontal axial suction and vertical upward discharge.

2. The radial part of the shell is especially suitable for conveying high-temperature, high-pressure and flammable and explosive liquids, and its installation method is supported by the horizontal center of the pump body.

3. The suction and discharge flanges of the pump are cast on the pump body, while the shaft seal cavity and the pump cover are integrated, and there is a water cooling cavity sleeve outside.

4. The bearing suspension is cast with a large oil pool for bearing lubrication. At the same time, it is equipped with a set of radial cylindrical bearings and a pair of back-to-back thrust ball bearings, which can bear radial and axial forces.

Use of pump

1, go

1), prepare the necessary tools.

2) Check the oil level in the oil storage chamber of the suspension, and control it at a position about 2mm away from the center line of the oil level gauge.

3), check whether the motor rotation direction is consistent with the pump steering, it is forbidden to reverse.

4) When rotating the coupling by hand, you should feel relaxed and even in weight, and pay attention to distinguish whether there are noises such as rubbing sound and foreign body rolling in the pump, and try to eliminate them if there are any.

5) Close the discharge pipe gate valve and outlet pressure gauge to discharge the air in the pump, so that the pump and suction pipe are filled with liquid.

6) When the temperature of the conveyed liquid is higher than 80℃, the heat pump should be preheated uniformly, and the conveyed high-temperature liquid should be injected into the pump body, and the cold water pipe and leakage control cock in the sealed cavity should be opened everywhere to check its flow and temperature.

7), start the motor (preferably inching, confirm the pump rotation direction is correct before formal operation), open the inlet and outlet pressure gauges, and then slowly open the outlet pipeline gate valve to the required position, and jump the leakage control cock in the sealed room to the appropriate position.

Step 2 operate

1), regularly check the temperature rise of the pump and motor, the temperature rise of the bearing should not be greater than 35℃, and the limit temperature should not be greater than 75℃.

2) Pay attention to the change of oil level in the oil storage chamber of the suspension, and always control it within the specified range. In order to keep the oil clean and well lubricated, new oil should be replaced regularly according to the actual situation of field use.

3), pay attention to the leakage of packing gland, it is advisable to drop water.

4), in the process of operation, found that there is abnormal sound or other faults, should immediately stop and check, and then continue to run after troubleshooting.

5) Never use the gate valve on the suction line to adjust the flow to avoid steam turbidity.

Step 3 stop the car

1), slowly close the extrusion gate valve and stop the motor.

2) Close the inlet and outlet pressure gauges and drain the liquid in the pump.

3) After the pump cools, turn off the cooling pipe switch.

4) When the pump is not used for a long time, it must be cleaned, especially the sealed cavity. It is best to disassemble the pump, clean it, reinstall it, coat it with antirust oil, and keep it properly after closing the inlet of the pump.

Le Wei Water Pump is one of the top manufacturers of pumps and pump systems in the world, and its products are mainly used in heating, refrigeration, air conditioning technology, water supply and sewage treatment. In fact, Le Wei Water Pump is a very famous brand. Today, Bian Xiao has introduced many Loewe pumps. I believe everyone has a certain understanding of Le Wei pumps. When choosing, you might as well consider these methods introduced by Bian Xiao. I hope my introduction will be helpful to readers.
