Mud pump is a pump products, its performance in the two main parameters is the displacement and stress. Displacement to per minute discharged from a number of liters calculation, it and the hole diameter and the required washing liquid from the bottom of

Self priming centrifugal pump is a new type of agricultural water pump designed and manufactured in our country in recent years. It is not the end of valve, before starting to pump the water poured into a small, start, can automatic vacuum water. After th

No water by pumping liquid density and particle size is too high; plug flow; impeller to fault; bar pumped into the impeller is card; outlet pipe above the level of rated head height.
Inadequate flow, head low. The voltage is low, the impeller to the wro

Before the pump should be used to check the motor winding insulation resistance, such as less than.
Pump body inlet at the gap between the impeller and the oil seal if more than 2mm should be replaced by wear resistant oil seal.

Installation and use of sewage pump without clogging pipeline:1. First check whether the external fasteners in the transport of loose.2. Check if the power sup

Correct maintenance of fire pumps, especially preventive maintenance, is the easiest and most economical maintenance, so it is the key to extend the service life and reduce the cost.

Centrifugal pump elevation adjustment is easy to pump and pipeline connection. In general the elevation to pump axis for measuring points, to pump based on calibration of foundation elevation is used as the measuring datum, level connectivity is measured.

Valve is a pipeline system is the indispensable part, its quality is good or bad directly affects production and safety. The problem is that they also is precisely will damage undoubtedly components, because the valve sealing surface due to the wear of th

Centrifugal pumps (in addition to the pump self-priming) before starting to the water pump and a water inlet tube filled with water, or pump cannot pumping work. After the start of the centrifugal pump water, often because of the air in the pump is not ro

When the gas escapes from the system, the gas will be along the pipeline to climb and eventually gathered in the highest point of the system, and automatic exhaust valve is generally installed at the highest point of the system, when the gas enters the e

Centrifugal fan is a DC motor speed control, the speed of the speed is through an adjustable resistance change of thyristor conduction angle, and then by the controllable silicon control rectifier after arrival at both ends of the motor voltage, in order

Centrifugal fan is mainly composed of: impeller, casing, shaft coupling, shaft. Impeller is the wind pressure is generated and energy transfer of main work parts; housing mainly used to introduce gas and exhaust gas, while the gas part of kinetic energy i

There are some fault of pressure reducing valve. Like outlet pressure is a main fault.

Control valve with its superior product performance and known, but in the use of the process often inexplicable stuck or jam makes people very headache, then there is no simple way to prevent or block?

Suction end of the valve is actually a check valve, which ensures flow only from a pool into the suction tube can not turn the clock back, so if the suction pipe full of water, despite the elevation axis pump the water level above the pool work, but becau

Pump performance parameters of the main flow and head, in addition to the shaft power, speed and the necessary cavitation margin. Flow is defined in unit time through the pump outlet output quantity of the liquid, the general use of the volume flow rate;

Ceramic valves are often used in bad working conditions, the installation in heavy process pipeline, the working conditions are extremely complex, if there are problems, because of its bulky, hard to pinpoint the problem, often let people stranded, also i

A successful and predictable maintenance strategy for the motor drive pump system should include the application of the on-line monitoring function for the intelligent pumping system. The relevant monitoring information can be transmitted to the equipment

The initial purchase price of a process pump is generally less than 15% of its life cycle cost (LCC). A 50 HP pump, whose life cycle costs include installation, operation, maintenance, and system maintenance costs, which are several times the original pur

Explosion proof centrifugal pump is widely used in the chemical industry system. It don't in the ordinary centrifugal pump, the configuration of the explosion-proof motor, has the performance adaptation range (including flow, pressure head and the convey

Vertical multistage centrifugal pump is a centrifugal pump, in the working principle, to comply with the general law of the centrifugal pump. Multi stage pump, the use of oil seal between the moving parts of the gap between the reduction of harmful space

Water pump including electric reciprocating pump in the working process is a part of the energy loss, including mechanical, wear volume loss and hydraulic loss, mechanical loss is finger pump shaft seal friction, bearing friction, the surface of the impel

Centrifugal pump is widely used at present in oil and natural gas, petrochemical, chemical, iron and steel, electric power, food and beverage, pharmaceutical and water treatment industry. How to economically and efficiently control pump output flow had tr

Most of the submersible sewage pump mechanical seal after dismantling, static and dynamic ring of the auxiliary seal, and some have been rotten, and some have been rotten, resulting in a large number of mechanical seal leakage and even the phenomenon of g

From the delivery of materials to analyze: if containing a lot of hard dirt, the submersible pump flow materials will accelerate the wear and tear, but in conveying similar to lubricating material, to prolong the lifetime of. Therefore, there is no indust
