The electric submersible pump (hereinafter referred to as ESP) is a kind of high efficiency, high yield, suitable for deep mechanical oil recovery equipment. According to the data, the average liquid production of electric submersible pump rod pump is mo

Slurry pump market with the adjustment of national policy in recent years, is widely used in the new industry, has entered a rapid development period, with the development of economy, the national sewage management, governance, subway, construction of a l

1. Matching power and pump (pump) rated power to match. General a number of pumps required supporting kW power, there are clear provisions in the pump nameplate. If you do not support, dynamic power is too large, it will cause a "big car Mara", a waste

Submersible sewage pump is mainly used for non corrosive particles, fibers, dirt containing conveying liquid, widely used in many fields of national economy, such as farmland, garden drainage and irrigation; rural biogas digesters, septic tanks, sewage an

During the use of the sewage pump to discover the problem of leakage, which should be the right way to solve the problem, is the focus should be done at present. From the current situation of sewage pump leakage were observed from the need to buy time, if

Many areas will use self-priming pump for workshop or oily water stains in the processing, general heavy pollution areas one month will be used once, if not very serious in general about three months once. At this point how to store the pump for storage o

1.Ready to place the pump part of worktable (ground) and disassembly tool, do not leave around any indiscriminate use, so as not to damage the pump parts.
2.And confirmed before the motor is in maintenance state; unscrew the gas plug, with Straw put th

Key points for rapid maintenance of pipeline pump:

1.Every 500 hours of operation, should release the sealing plug seat, out of residual oil cavity with a syringe; added to the sealed cavity qualified 20 mechanical oil to the cavity half of the volume

Horizontal pipeline centrifugal pump is mainly used in industry and city water supply and drainage, high-rise building pressurized water, garden irrigation, fire booster long-distance transportation, HVAC refrigeration cycle, bathroom water pressurization

Multistage boiler feedwater pump can be used for hot and cold water high pressure in the operation system and the circulation of pressurized, high-rise building water supply, fire pumps in parallel, boiler water and cooling water system and various fluid

Many people buy pumps do not know how to use, said the water suction does not come up, how the vibration of such a large, and then take away, for this case, small series for you to explain how to properly install the pipeline centrifugal pump.

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
