Coupling problem The main function of the coupling is to connect the pump and the motor to rotate together and transmit the torque. There is an air bag in the outlet pipeline. Can not work normally.This situation often occurs in large and medium-sized water pumps that use sliding bearings. Bending machine pump shaft

The outlet valve opening is too small. 2. (2) When the pump is repaired and installed on the inlet and outlet pipelines, due to the changes in pipeline displacement, especially the newly commissioned pipeline, the first time the inlet and outlet flanges are removed, the relative displacement of the flanges is very large. In severe cases, pump jams occur. Fives. (4) When replacing the pump, because the pump base does not match the foundation bolts, the holes in [...]

If adjusting the inlet and outlet valves does not achieve the effect, you can adjust the safety valve at the outlet of the pump.The outlet pressure of the screw pump is achieved by adjusting the inlet and outlet to achieve the required pressure. When the pressure of the screw pump is low, the reasons should be eliminated from the following steps from simple to complex. 1. Check the pump's operating current when the pump is running to see if it is consistent with the description in the manual. Fully open the suction valve of the pump,

or try to increase the suction flow as much as possible, such as adding a small pump in front of the suction. Disassemble the gland of the pressure reducing valve, and use a wrench to [...]

Can be started. In areas Sewage Pumps Manufacturers where groundwater is used for irrigation, the buried depth of underground water pipes should not exceed 10 meters (including the depth of the pump house). The centrifugal pump automatic water supply device solves the shortcomings of the pump in the automatic water supply system.

The pump types used are generally self-priming centrifugal pumps, deep well pumps and submersible pumps. Scope of application: Ordinary centrifugal pump automatic water supply devices can be used for water-saving irrigation communities with a certain scale, rural tap water and urban tap water projects, and industrial water communities. Installation of centrifugal pump, on the ground well pipe, first install the bottom valve to connect the well pipe tee,

install the valve and the hand pressure well head in turn [...]

The anchor bolts must be tightened when installing the pipeline centrifugal pump to avoid the impact of vibration on the pump performance during starting. For the convenience of maintenance and safe use of the pipeline centrifugal pump, install a regulating valve on the inlet and outlet pipes of the pump and a pressure gauge near the outlet of the pump to ensure the operation within the rated head and flow range and increase

The service life of the pump. Before installing the pipeline centrifugal pump, check whether the weight of the pipeline is added to the pump to avoid deformation of the pump body. Turn the pump shaft after installation, there should be no friction or jamming of the impeller. 2. 5. 4. Before installing the pipeline centrifugal pump, check whether [...]

The clearance value between China wholesale deep well borehole pumps bearing body and the spherical top of the bearing box is qualified. 2. 2. Coupling. Use a stress relief system. Find the fatigue of the vibrating support in time to prevent the natural frequency from falling due to the decrease in strength and rigidity. 2

Ways to eliminate pump vibration 2. 3. In addition, the loosening of foundation anchor bolts leads to a decrease in restraint rigidity and aggravates the vibration of the motor. Impeller. In addition, for hot water pumps that deliver hot water, if the preheating of the pump is uneven before starting,

or the sliding pin system of the water pump is not working properly, thermal expansion of the pump set will be induced, which will induce violent [...]

Non-sudden high water Surface Pumps Manufacturers. When the water filling port turns over a little and the engine temperature is low before and high, it indicates that the water distribution pipe is damaged or blocked and should be replaced in time. In short, there are many reasons for the overheating of the electric diaphragm pump engine. If a radiating pipe is severely broken, the two ends can be clamped and blocked. 2. Check if the pump body and pipeline leak. Reasons for the high temperature of the electric diaphragm pump engine:   1.

Fourth, the diaphragm pump outlet liquid contains a large number of bubbles 1. If the diaphragm pump fails, you can use these methods to check first. 2. Reduce the running speed of the pump to adjust the viscosity [...]
