The method of overall installation of water pump and motor

A steel base or motor is flanged mounted on the pump is required!

The water pump and motor are usually purchased as one, that is, the purchase is accompanied by a base, a motor, a water pump, a coupling, etc. In most cases, you don't need to do much work, mainly to install suction pipes and drain pipes.

If the purchased pump is a large pump or the manufacturer is not equipped with a large base, the user needs to design and solve it by himself.

The base of the pump and motor can be a cast base, a welded structure base, or a concrete base.

After the casting base and welded structure base are made, the water pump and motor can be installed.

The concrete base needs to be designed according to the load situation, and the motor, pump, coupling, etc. will be installed after the civil construction is completed.

The accuracy requirements for the installation of pumps, motors and couplings are usually that the radial runout deviation of the two axes is not more than millimeters, and the deviation of the angle of the two axes is not more than 30"。

After the water pump is transported to the designated position, the equipment is hoisted and installed, and it is accurately located on the equipment inertia pedestal that has been made, and all the pumps are connected with a funnel to contain the water leaked by the sealing gasket, and there is a pipeline to discharge to the nearest drainage point.

The concrete strength of the foundation before the pump is in place, the coordinates, elevation, size and the position of the bolt hole must meet the requirements of the detailed design drawing, and the anchor bolts should be vertical, tightened and in close contact with the equipment base during installation.

The water pump horn group is placed in the correct position, stable and close contact, and each group does not exceed 3 pieces.

Install brackets on the pipes near the pump so that there is no weight attached to the pump casing.

The inlet and outlet of each pump should be equipped with exhaust valves, drain ports and pressure gauge joints at both ends, and the water inlet and outlet should be equipped with flanges for pipeline connection.

Submersible sewage pumps: There are a number of submersible sewage pumps in the basement sump of this project, and there are two other installation methods: fixed automatic coupling installation system and mobile free installation system. It is very convenient to install and maintain, and people do not have to go into the sewage pit for this purpose.

When the pump is installed, attention should be paid to the position of each pump, the same row of pumps, the central axis of each pump should be parallel to each other, and the center line of the water outlet or water inlet of the pump should be in a straight line.

The test run of the water pump should not be less than 2 hours under the design load, and meet the following requirements:

a. There should be no abnormal vibration and sound during operation, the seals should not leak, and the fastening and jointing parts should not be loosened;

b. The temperature rise of the bearing must comply with the provisions of the equipment manual, the maximum temperature of the sliding bearing shall not exceed 70 degrees, and the maximum temperature of the rolling bearing shall not exceed 75 degrees;

c. The temperature rise of the shaft seal packing should be normal, and the leakage of the ordinary packing should not be greater than 35-60ml h in the absence of special requirements, and the leakage of the mechanical seal should not be greater than 10ml h.

d. The current and power of the motor should not exceed the rated value.

Can you be specific? The topic is a bit big.

Summary. 2. Water pump and electric installation (1) The water pump and motor equipment are complete, and there should be no history of missing parts, damage and rust, and the nozzle protection and plugging cover should be intact.

Dear, hello draft bridge, very high key round Mengxing your question, help you find the following answers: motor and pump cavity connection construction plan pro, the plan is as follows.

Pro, the method is as follows: before the base surface cleaning equipment is in place, it is necessary to wipe off the yard spring oil stain reputation of the base surface of the equipment, dirt and other dirt, and the template and debris division in the reserved hole of the anchor bolts, and chisel out the hemp late Bi resistant surface to ensure the quality of the grouting.

2. Pump and Aberdeen return electric installation (1) The pump and motor equipment are complete, and there should be no history of missing parts, damage and rust, and the nozzle protection book and plugging cover should be complete.

2) Before the motor is connected to the pump, the steering of the motor should be tested separately and then connected after confirmation. (3) The active front shaft and the driven shaft are aligned, and after the connection, the car should be flexible, (4) When the pipeline is connected to the pump, the flange center should be quasi-ascending, and should not be forcibly connected, resulting in a different appearance.

A steel base or motor is flanged mounted on the pump is required!

Buy a submersible pump, just connect the water pipe and power cord.

1. The original factory generally has a supporting motor, for example, the domestic Kaiquan water pump comes with a complete set.

2. If you are damaged during use, it is best to buy the original motor.

3. Because, whether the center height of the motor is the same, whether the base is compatible with the original, etc., should be considered.

4. If it is preliminarily said: the power of the motor and the power required by the pump should be considered to have a margin.

5. The power supply of the motor should be matched with the original. For example, it is not the same whether it is 220V or 380V.

6. It is recommended to use the original model motor, or contact the original manufacturer.

7. The most daring idea is to replace the motor and water pump as a whole. The price is higher.

Upstairs is very right, the motor replacement requirements are quite high, the best is to find the original factory, in fact, you can find some control cabinets to start the pump, they can effectively protect the motor, and can operate automatically, we are a control cabinet manufacturer, I hope to have the opportunity to cooperate.
