Products Name:high head sewage pump of Liquid
A, product introduction:
YW type liquid type non clogging sewage pump is Lian Sheng on the basis of the introduction of foreign advanced technology, combined with the use of domestic water pump features a new generation of pump products designed and produced successfully, with significant energy saving effect, anti winding, no blocking, automatic installation and automatic control characteristics, in the carriage of solid particles and long fiber waste, has a unique effect.
Liquid sewage pump hydraulic performance of advanced, mature, product performance testing, the indicators are in line with the requirements of the relevant design.
Lian Sheng products using computer design and optimization, the company has strong technical force, rich production experience and perfect testing means, so as to ensure stable and reliable product quality.
Two, applicable scope:
YW type liquid type non clogging sewage pump is suitable for chemical, petroleum, pharmaceutical, mining, paper, power plant and the city sewage treatment, municipal engineering, public facilities, sewage and other conveying sewage with particles.
Three, product features:
1. Anti-jamming design of hydraulic components, big channel, greatly improving the through capacity of sewage, solid particles can effectively for 50% of pump diameter by 5 times of pump diameter and the diameter of fiber material.
2, reasonable design, reasonable matching motor, high efficiency, energy-saving effect is remarkable.
3. Dual path series seal, mechanical seal made of tungsten carbide hard wear-resistant, durable, wear-resistant, can pump the security more than 8000 hours of continuous operation.
4, the pump has the advantages of compact structure, small volume, convenient to move, simple installation.
5, automatic control cabinet is equipped with liquid level, according to the change of liquid level required, automatically control the pump to start and stop, without special care, is extremely easy to use.
6, liquid type non clogging sewage pump is a vertical structure, when the pump body immersed in a fluid is easy to start, there is no exhaust time, at the same time with no leakage and other characteristics, under fluid depth is 15 meters.
7, shaft connecting structure is advanced and reliable, pump and motor shaft coupling, pump shaft size precision, ensure the smooth operation of the pump, with sufficient safety factor.
8, sewage pump pipe installation and pipe installation two, supporting a disk and a square plate mounting, suitable for different needs.
Four, the technical parameters:
1. Traffic: 8-2600m3/h;
2. Head: 7-60m;
3. Speed: 740-2900r/min;
4. Aperture: φ 25- φ 500;
5. The temperature range of -15-+60 celsius;
6. Working pressure: ≤ 1.0Mpa.
| fault phenomenon |
failure cause |
elimination methods |
| |
1.No power supply or one or two phase power supply is needed |
Check all phases of power supply and restore power supply
|
| |
2.Poor contact of ac contactor and burning of coil |
Repair or replace contactors
|
| can not start |
3.
The power switch is not closed, malfunction or damaged
|
Close the switch and replace it if the power indicator does not turn on |
| |
4.
Thermal relay trip or damage
|
Check whether the motor is blocked, find out the reason and eliminate it.Manual reset is replaced if it cannot be started |
| |
Water level is too low |
Put water in the sink
|
| |
The motor burned |
Repair or replace the motor
|
| |
1.Line is loose |
Check wiring and tighten connectors
|
| |
2.Frequency converter malfunction |
Check the fault content, check the cause according to the frequency converter manual, and restart after reset.Or disconnect the inverter power supply for a few seconds, the inverter fault reset before starting. |
| The manual is normal |
3The frequency converter is damaged |
Repair or replace |
| Automatic transmission failure |
4.Pressure switch damage |
Repair or replace |
| |
5The pressure transmitter is damaged |
Repair or replace |
| |
6.Switch failure |
Repair or replace |
| Pump non - suction pressure gauge pointer to beat violently |
Insufficient water supply for perfusion, air leakage at the connection between pipeline and instrument |
Check pipeline and bottom valve, refill water diversion. Tighten air leakage |
The pump consumes too much power
|
Too much flow, impeller wear
|
Check whether the pump shaft is bent, replace the impeller, close the outlet valve to reduce the flow |
