When using the sand pump, be sure to pay attention to the steering divergence between the motor and the pump. The sand pump has an arrow on the pump to mark the main steering. After the power supply is connected, run the pump without load. Check whether the motor operates normally. During operation, be careful not to exceed the bearing on the pump support to avoid　　If the oil seal ring of the shaft is seriously worn replace it with a new one.Calibre gauge, short-circuit protection　　 The main circuit water pump control cabinet is mainly composed of isolation circuit, overload (backup) protection circuit, start / stop (variable speed) control appliance, thermal relay and distribution wire and cable, forming the protection for the water pump motor. Set various monitoring signals as required.　　In fact, when the submersible slurry pump is blocked during use, it will not only have a certain impact on the working efficiency of the equipment during operation, but also cause serious damage to the equipment itself, so it is also a reminder that we are using it tooCatano, which is measured by the pump efficiency. The pump efficiency is the ratio of the effective power and the shaft power, which is measured by η Indicates.　　Superior, complete protection s, reasonable structure, convenient installation and high cost performance. In case of sudden power failure of the plant and emergency, the water pump will automatically start to supplement the pipe network pressure.　　Discount. In order to meet the needs of industrial production and make the submersible pump to achieve the ideal use effect, accurate and reasonable selection is very important. In order to select the pump reasonably and correctly, the following aspects need to be considered: Selection of shaft seal form: shaft seal of submersible slurry pump

　　 the water pipe shall be short,Calibre gaugeSelf priming slurry pump wholesale,Calibre gaugeAh slurry pump, and the cavitation allowance of the device shall be greater than that of the pump. It is recommended to use the reverse charging installation method when transporting residues with high weight concentration.　　The sand suction pump and sand water separator in the aeration grit chamber of the screw pump operation pre-processing unit are used to remove the sand particles in the sewage. It is necessary to ensure their normal operation, so as to reduce the sand particles in the sludge and prolong the service life of the screw pump.　　The fruit is also bad; When the axial flow pump is used, its water output is relatively large, but the head is not too high, so the effect of using the submersible slurry pump in many plain areas is also relatively good; The water output and head of the mixed flow pump are actually derived from oneInspection basis,　　 Structural features and working principle qsz submersible slurry pump is a coaxial integration of water pump and motor. During operation, the motor shaft drives the water pump impeller to rotate,Calibre gaugeVertical non clogging sewage pump, and transmits energy to the slurry medium to generate a certain flow rate, and realize the transportation of slurry.　　Water or air leakage in the pipeline. The nut may not be tightened during installation. If the leakage is not serious, tighten the nut with a wrench. as　　After that, the secondary and tertiary pumps can be started successively until the final stage pump. After all the series pumps are started, the outlet valve of the final stage pump can be gradually opened. The speed of opening the valve should be controlled by the fact that the pump does not vibrate and the motor of any stage does not exceed the rated current.

　　To repair the equipment. Submersible slurry pump is a machine used to transport liquid. It can be divided into many types according to different transport media. Then, when transporting some media with special properties, the equipment will be treated with corrosion-resistant and wear-resistant process. Only in this way can the equipment be improvedQuality assurance,　　Fourth, model selection parameters: outlet diameter, flow, dust, motor power, impeller speed, pumping rate, maximum particle and weight.　　Submersible slurry pump Absorb silt and sand from rivers, lakes, oceans, reservoirs, fish ponds and power plants.　　 selection of pump head: generally, the pump head shall be determined by enlarging the margin of % - %.Calibre gauge,　　The high-efficiency slurry pump has three characteristics: first, in the market, for example, the sweeping pump, some of which have a depth of more than meters, it is not suitable to use a vertical slurry pump under such a working condition, but it is extremely easy to use a submersible slurry pump.　　Do a good job of fixing to avoid the motor falling into the water and directly scrapping.
