Carefully check the mechanical seal part number is not in line with the needs and the element damage, especially dynamic and static ring has no bumps, cracks, deformation and other defects to take .

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

Small submersible pump light and light, farmland irrigation and farm life water can not be. In order to avoid the use of the process of accidents, to extend the service life, to play its excellent performance, the use should pay attention to seven points.

Heat pump temperature in 120 degrees or less, the installation is divided into vertical and horizontal 2. Water circulating pump failure is mainly no water, inadequate flow, noise vibration, leakage of several faults under the specific explanation of vari

Sewage pump is also called the sewage pump can be used to transport containing organic matter, inorganic substances or mineral solid waste water. Sewage pump is single stage centrifugal pumps and does not have the self suction function, through the impell

The installation of leakage protector is also called the protection of life, it's role from the "life" of the three words can be understood. Because submersible pump works under water, easy to leakage caused by power loss or even lead to electric shock

The discharge valve is easy to operate, free to open, flexible and reliable movement; the valve valve assembly and maintenance is simple, the sealing structure is reasonable, and the sealing ring is convenient and practical

The flow characteristics of the control valve are used to compensate for the different characteristics of the controlled object. If the matching flow characteristic is not suitable, can make the control system control quality variation. For example, the s

The working principle of the multistage centrifugal pump is a centrifugal force generated by the rotation of the impeller, impeller channel in the water under the action of centrifugal force left periphery flowing into the pump shell, reduce the pressure

The valve structure is simple, can be rotated by the valve stem and lift the principle of the valve to achieve the open or cut off, and to ensure that the valve seal and seal on the function. Due to the special structure of the structure of the movement,

Simply type throttle valve outside the load changes will lead to changes in the flow of external load change, or the implementation of the speed requirements of the system is very stable system, should use the speed control valve
Oil quality deterioratio

Select the appropriate satisfaction of the trap is the need to have the know-how: to understand the knowledge of the trap is a necessary condition. Hydrophobic valve is one of the main accessories of steam and condensate piping system. If the trap failed,

First check valve and gate valve connection bolts are tightened, if not tightened, the sealing gasket ring and the flange sealing surface is not fully integrated often lead to leakage. The bolts and nuts should be checked in sequence, and all the bolts sh

Pump vibration is very annoying for us, not only affect the work of the pump, but also bring noise

Electric control valve in the course of time will often appear leakage problems, this situation is sometimes also random can not be avoided. Because there are a lot of reasons, but the direct reason is that the problem is sealed, the seal is not in place.

In various cities, the problem of urban sewage is a common problem.

Fire pump is widely used in daily life, and is widely used in many departments, such as environmental protection, water treatment and fire control. This makes the fire pump fault elimination method is particularly important, and the common faults of fire

ISG type single-stage single suction vertical centrifugal pump pipeline pump, centrifugal pump, centrifugal pump, single stage centrifugal pump, vertical pump, booster pump, hot water pump, a circulating pump, booster pump,, is a single-stage single suct

Electric control valve is in accordance with high control precision, especially in the flow of control, and during installation structure have obvious advantages, and widely used in the industrial control system, or for us to use the electric control valv

The failure of valve stem normally mostly due to excessive operation resulting in threaded stem injury, stem caused by the bending or stem and nut with tolerances are not allowed, nut tilt, threads are caused by corrosive medium, corrosion and other reaso

Knife gate valve is commonly used in conveying system equipment, belong to fully open fully closed valve, the main role is to open, close the pipeline transport system. Can be installed in the cyclone to mine, tailings or double loop pipeline, etc..

All things with a long time will appear some problems, whether it is their own or man-made is possible, it is because of the use of more, the problem will be followed. Therefore, to find a reasonable way to solve is the key. Like the fire pump, it must be

The use of air source heat pump water heater to provide hot water, do not know how to calculate the hot water circulation pump,

The failures include that no water, noise and vibration, lack of water, shaft power consumption is too large

ZW self priming sewage pump is a collection of self suction and non clogging sewage in one, the use of axial flow of mixed type, and through the pump body.
