Since the water suction sewage pump:
1. Reasons: the pump body does not add liquid storage or storage of the lack of. Methods: plus foot.
2. Reasons: the elimination. Method of air leakage in the suction pipe: eliminating the leakage of the pipeline.
Self suction non clogging sewage pump failure causes have 5 reasons:
1. Self-priming sewage pump water.
2. Self-priming sewage pump water shortage.
3. Self-priming sewage pump noise, vibration is too large.
4. Self-priming sewage pump bearing temperat
Valve is not like a manual valve, after the installation of a few more to the management, maintenance, it must be ground maintenance to ensure the normal operation and longer service life. The method as follow:
1. Growth of the throttle channel
2. Chang
Valve is not like a manual valve, after the installation of a few more to the management, maintenance, it must be ground maintenance to ensure the normal operation and longer service life. The method include as follow:
1. Opening work
2. Reduce the incr
The vacuum pump can be divided into three categories according to the scope of use and the efficiency of the pumping:
1. The general water pump, pressure can reach 1.333~100kPa (10~760mmHg) for the "rough" vacuum.
2. Oil pump, pressure up to 0.133~133
Vacuum pump is good or bad depends on its mechanical structure and the quality of oil, the use of vacuum pumps must be good to protect it.
If a large distillation of volatile organic solvent, organic solvent will be oil absorption results in an increase
Using of self priming pump include as follow:
1. Preparation and inspection before starting.
2. Start up and operate.
3. Stop the pump
1. In the pump and motor direct connection drive, should pay attention to the pump shaft and the motor output coaxial degree; pump installation accuracy and had great influence on the pump running stability and service life. Therefore, it is necessary to
Safety valve is a safety valve, its opening and closing parts under the action of external force in a normally closed state, when the equipment or pipeline in the medium pressure increases, more than the set value automatically open, discharged to the out
The normal operation of pumps, accompanied by sound always has a certain rhythm and rhythm. As long as the familiar and master these normal melody and rhythm, human auditory function can be compared through the device is the heavy, complex and strange, ch
The net distance between the two pumps should not be less than 700mm, the front end of the pump operating channel width should not be less than 1000mm, for the multi-stage pump, the front end of the pump overhaul channel width should not be less than 1800
1. For open or semi open centrifugal pumps arranged, a pump to pump the axis of the motor and the pipe gallery axis perpendicular to the.

2. For the indoor layout of the pump, when the liquid temperature is higher than the transmission of spontaneous c
Open layout of the pipeline centrifugal pump arranged in the gallery below or on the side of the tube, the liquid can be arranged in the vicinity of suction device. The main advantage is well ventilated, easy operation and maintenance, if pump arranged i
In order to enhance the use of submersible pump control, prevention of corruption facilities, to prevent the leakage of submersible pump or cable to produce, to ensure personal insurance, please note the following points:
1. All the submersible pump into
The hot water circulation pump mainly has the following several kinds of faults: does not have the water, the insufficient flow, the noise and vibration, the water leakage
1. Liquid mixed with gas. Improved suction pressure exhaust.
2. Produce cavitation. Vacuum reduction.
3. Pipe support instability. Solid line.
4. Bearing damage. Replace bearing.
5. Motor overload heating operation. Regulating flow off small outlet va
