The reasons are as follows: 1. If the pump is not used for a long time, the pump body and pump cover made of carbon steel are easy to check and corrode, and the mechanical seal is sealed.
It is also prone to failure.
2. Make sure that the standby pump is in a normal state, and once the working pump fails, the standby pump can be started immediately to avoid other losses.
A water pump is a machine that transports or pressurizes a liquid. It will be the mechanical energy of the prime mover.
or other external energy is transmitted to the liquid, so that the liquid energy increases, mainly used to transport liquids including water, oil, acid and alkali liquid, emulsion, suspension emulsion and liquid metal.
It can also convey liquids, gaseous mixtures and liquids containing suspended solids. The technical parameters of pump performance include flow, suction lift, head, shaft power, water power, efficiency, etc.; According to different working principles, it can be divided into volumetric water pumps, vane pumps and other types. Positive displacement pumps use changes in the volume of their studios to transfer energy; Vane pumps use the interaction between rotary vanes and water to transfer energy, and there are centrifugal pumps.
Axial flow pumps and mixed-flow pumps.
-
The pump will heat up for a long time, especially when the actual flow is much smaller than the design flow rate (such as the life frequency conversion constant pressure water supply equipment, in order to maintain the pressure when few people use water at night, the pump will still run all the time), at this time, the energy consumption of the pump motor is basically consumed in the heat of the pump, under this working condition, if the same pump has been running, the pump is seriously heated, which will affect the service life of the pump, and will make the water in the pipeline become hot water, and the pump motor will be burned directly.
-
The pump itself is not designed to work full-time and needs to be operated intermittently to facilitate mutual input, maintenance and backup. Many key occasions are used in one hand.
-
In the case that the No. 1 pump can not be started if there is a problem, the current will be overcurrent, and the thermal relay will be protected, at this time, the normally open point of the thermal relay is closed, on the one hand, it can be connected to the fault lamp, and on the other hand, the normally open point can be used to merge the contactor start signal of the No. 2 pump, so that the No. 2 pump can run.
-
Only then can you use the fault signal to lock the operating signal of another machine.
-
The normally open and normally closed combination on the contactor is fine.

There could be a variety of reasons that cause the pump to stop working after turning for a while, here are some possible reasons and how to fix it:
Power Issues: The water pump needs sufficient voltage and current to work properly. If the power supply is unstable or the wires are in poor contact, it may cause the water pump to stop working. The solution is to check whether the power supply is firmly connected, whether the wire is damaged or aged, and ensure that the power supply is stable.
Clogged water pump: If the inlet or outlet of the water pump is blocked, the water pump may stop working after a while. The solution is to clean the pump and pipes and make sure that the pump's filters and other parts are not damaged.
Pump damage: If the pump's motor or other flushing parts are damaged, it may cause the pump to stop working. The solution is to locate the damaged part and have it repaired or replaced.
Pipe pressure is too high or too low: If the pipe pressure is too high or too low, the pump may stop working. The solution is to check if the pipe pressure is normal and adjust the pipe valve or pump settings as needed.
Pump running for too long: If the pump works continuously for too long, it may cause overheating and stop working. The solution is to give the pump sufficient rest time and make sure that the pump can cool down properly.
If you're not sure how to fix the problem, it's best to contact a professional technician for inspection and repair.
