Self priming centrifugal pump over-current components are: inhalation room, impeller, the chamber pressure of three parts. Impeller chamber is the core of the pump, but also the core of the flow components. Pump through the impeller to the liquid for work

The basic structure of the self suction centrifugal pump is composed of six parts, namely, impeller, pump body, pump shaft, bearing, seal ring, stuffing box.

1.Strength properties
2.Sealing performance
3.Flow media
4.Opening and closing force and opening and closing torque
5.Opening and closing speed
6. Action sensitivity and reliability
7. Service life

When the pump is running, it is treated as the following method:

Cause of failure :

1.Foundation bolt loose or installation is not perfect;

2.Pump and motor installation is not concentric;

3.Into the air or the occurrence of cavitation;

1. Spring compression, the greater the sealing effect is better. In fact, excessive compression spring can lead to rapid wear friction, instantaneous burning; excessive compression spring loses its ability to adjust ring face, resulting in seal failure.

Double suction centrifugal pump seal main types of mechanical seals and packing, sealing the 2 categories, usually leakage mainly in the following five:
1.The seal between the sleeve and the shaft;
2. Ring and shaft seal;
3. Dynamic and static ri

Multi-stage pump is a centrifugal pump, but also rely on the rotation of the impeller in the acquisition of centrifugal force, so that the material. When the gas density reaches the working range of the mechanical vacuum pump, the vacuum pump is drawn out

Cleaning is an important part of the repair work, the quality of the cleaning machine has a great influence on the quality of machine repair. It is one of the problems to be considered that the correct cleaning method is used to improve the cleaning quali

Water as a submersible pump unit to be charged into the underwater operation, so the motor seal and insulation performance must be reliable, installation and use of technology to be strict. A slight problem will be a problem, the lighter parts of the wear

Sewage pump is a non clogging pump, with a variety of forms such as diving and dry two, most often the submersible WQ type submersible sewage pump, the most common dry sewage pump as W horizontal and WL vertical sewage pump sewage pump two. Mainly used fo

Submersible sewage pump in the municipal engineering, industry, hospitals, construction, hotels, water conservancy construction plays a very important role in all walks of life.

Submersible sewage pump is a pump and motor connected, and at the same time into the work of the pump liquid products, compared with the general horizontal or vertical sewage pump pump, submersible sewage pump has the following obvious advantages:

1.C

1. Check the pump and motor after the opening, if confirmed without any due to loading and unloading and transportation in the process of damage and loosening fastening devices. The inlet and outlet of the pump cover intact, no dust and dirt into the pump

How to identify bearing manufacturers are regular, quality is reliable, the method is:
1.Outside the packaging is clear
2. The word is clear
3.Whether there is noise
4.Whether the surface traces of muddy
5. The chamfer is uniform

Vertical axial flow pump main parts are: Trumpet pipe, impeller, guide vane, water pipe, pump shaft, bearing, stuffing, etc..

Widespread use of agricultural pumps (pumps), such as centrifugal pump, axial flow pump, submersible pump, mixed flow pump, in the use of existing power machinery and pump power matching unreasonable, burning machine, energy consumption and higher cost, r

Pump shell :
The role of the impeller is enclosed in a certain space for the role by the impeller suction and pressure of liquid. Pump casing made of more than a spiral case, it is also known as the spiral case. As the flow channel cross-sectional area i

Ordinary centrifugal pump transmission medium if the intrusion, generally do not need irrigation pump. Only need to open the gas valve before driving, let the media into the pump body can be. If it is a self suction pump, in the first car to fill the pump

1.Running, sliding bearing and reciprocating parts of the temperature rise shall not exceed 35 degrees, the maximum temperature shall not exceed 65 degrees Celsius; rolling bearing temperature rise shall not exceed 40 degrees Celsius, the maximum temperat

1. Reciprocating pump, gear pump, screw pump, such as the volume of the pump before the start, you must first open inlet and outlet valves.
2. The centrifugal pump at startup, should open the entrance valve, close the outlet valve, start the motor power
