The self-priming pump that has changed the self-priming height of the self-priming pump is added with a set of vacuum auxiliary device, then the self-priming ability of this self-priming China JET pumps factory pump is stronger, and the horizontal distance can pump up to about 150 meters, and the self-priming height The water can be pumped up quickly even at 9. The suction power of the suction pump is not large, and there is another situation that the mechanical seal of the self-priming pump is not tightly sealed, which makes it impossible to pump water..

A set of vacuum assist system can be added to the self-priming pump. What should I do if the suction power of the self-priming pump is not high? What should I do if the suction power of the self-priming pump is not high. What is the reason for the low suction of the self-priming pump? Conventional self-priming pumps include self-priming sewage pumps, self-priming centrifugal pumps, small stainless steel self-priming pumps and other self-priming pumps. In addition, the self-priming time is long, the water filling time is slow, and the self-priming height is high during the self-priming process.

In some cases, the self-priming pump can pump water up after the pump is filled up for the first time, but the pump stops several times. This is mostly due to the small pump cavity of the self-priming pump due to the tightness of the conventional self-priming pump inlet check valve after the pump is stopped.

The next time the pump is turned on after hours or one night, water must be added to the pump to pump up. These self-priming pumps use centrifugal pump impellers In addition, the small water storage volume of the pump body results in the low suction power of these types of self-priming pumps. 2. The water in the pump body is not very good, which causes the water in the pump body to flow backwards and part of the water is lost.2 meters. Therefore, the second start-up requires water to suck up the water

The suction pipe is permanently China drainage pumps factory on the ground, and the outlet pipe is usually installed overhead due to the deep pump room, usually on a bracket along the wall. When the connection between the suction pipe and the pump needs to be tapered, an eccentric size head should be used.7m/s to avoid deposits in the tube.5m/s.

The flow rate of the outlet pipe of the pipeline sewage pump self-priming pump outlet pipe is generally not less than 1. In order to facilitate the removal of the air accumulated in the suction pipe, the horizontal part of the suction pipe should be slightly raised along the direction of the water flow, and the pipe slope can be 0. When two or more sewage pumps share one outlet pipe, the outlet pipe of each pump should be equipped with a valve, and a check valve should be set between the valve and the pump; if the pump uses a separate outlet pipe, and the outlet is free When flow,

check valve is generally not necessary, so the valve should be installed in the horizontal section as far as possible to prevent dirt from depositing on the valve disc.7m/s.4~0. When the outlet pipe of the pump is connected to the outlet main pipe (connecting pipe), it shall not be connected from the bottom of the main pipe to avoid siltation in the outlet pipe of the pump when the pump stops running. The arrangement of common pipelines and their accessories and the laying of common pipelines shall ensure the convenience of use and repair of the water pump.

The bell mouth is installed in the sump of the sump.. If the pump is not self-filling, it should be started with a vacuum pump or water ejector, and it is not allowed to set a bottom valve on the suction pipe. When two or more pumps share one outlet pipe and only one pump works ,

Hot water circulating China JET pumps factory is suitable for energy, metallurgy, wood processing, chemical industry, textile, papermaking, and restaurants, bathrooms, hotels, boiler hot water pressurization cycle and urban housing heating cycle. This series of pumps are of horizontal structure, with integrated pump and machine, beautiful appearance and less floor space. Stainless steel horizontal pipeline pump product use: 1.. 4. The temperature of the medium used does not exceed 85°C. 4. The shaft seal adopts a mechanical seal, and the moving and static rings are made of hard alloy, which is resistant to wear, no leakage and long service life. 3.2020-03-26Stainless steel horizontal pipeline pump product features: 1.

The main reasons and treatment methods: ( 1) When the power cord is installed, the end is immersed in water or the power cord or signal line is damaged, causing water to enter; replace the cable or signal line, and dry the motor. (3) The outlet valve cannot be opened; check the valve and maintain it frequently. The main reason is that the check valve in the water outlet pipe or the flapper failed.. The disassembled seals and cables must not be used again. Feel free to expand. After all the pipelines are installed, the pressure strength and leakage test of the system should be carried out. (3)

The main reasons for the submersible pump causing excessive current, motor overload or overtemperature: (1) The working voltage is too low or too high; check the power supply voltage and adjust the output voltage. alarm and shutdown; before installation, check the quality of each sealing component; ensure that the end faces of each sealing component are in good contact during installation; check the phase-to-phase and ground insulation resistance of the motor and each alarm before operation Whether the sensing components of the system are intact.

The pump will reverse when the pump motor is powered off. If the above situation occurs during use, check whether the power phase sequence has changed. (8)
