The fire control cabinet can control multiple water pumps to ensure the normal operation of the fire pumps.　　Most of the time, we don&#;t know how to choose the pump when we buy it.

Then calibrate the pump shaft and motor shaft of the slurry pump to make them on the same horizontal line.Total quality management,　　 The submersible slurry pump usually relies on water cooling to dissipate heat. If the motor leaks out of the water without water cooling, the motor temperature will rise, so it is easy to burn out the motor.　　Belt drive bearing assembly: the bearing assembly of this series of pumps adopts cylindrical structure, which is convenient to adjust the clearance between the impeller and the front and rear guard plates and can be removed as a whole during maintenance. The bearing is lubricated with grease.　　Rate.lucky charm,　　 If the head of the submersible slurry pump is too low or the head is higher than the practical condition, the outlet valve can be turned down to increase the resistance to control the current.　　 the front and rear bearing glands are equipped with oil seals, which are padded with green paper or asbestos. There is a gap of .- mm between the rear gland and the bearing.　　The disc friction loss of the slurry pump impeller will decrease with the decrease of the impeller diameter, so that the pump efficiency of most low specific speed pumps will improve slightly after the impeller is cut. After cutting, keep the blades overlapped to a certain extent, and the degree of blade overlap will decrease with the addition of specific speed

　　Now you know the reason why the pump has air turbidity. In fact, this is a very common phenomenon. You don&#;t have to worry about it. Water pump can transport many things, such as water, oil,PiroerburHorizontal wear-resistant slurry pump, liquid metal, acid-base night and so on.

Slurry pump with mechanical seal　　When the water level reaches, the frequency of the frequency converter drops, and the slurry pump operates at a low speed. The higher the water level, the higher the speed. At the same time, the water level signal is transmitted to the control cabinet so that the operators can timely understand the liquid level. Through this control, the circulation in the slag slurry pool is basically unchanged　　There is a difference between submersible slurry pump and sewage pump. Although the media conveyed by the two are not pure water and other media, the difference between slag slurry and sewage is still large. Let&#;s take a look at the difference between the two.

　　 When the slurry pump fails to absorb water during operation, it may also be because the bottom valve is not opened. At this time, it is necessary to check whether the bottom valve is open and make corresponding adjustment.　　 for new or replaced deep well submersible pumps, after hours of use, check whether the seal is good. In the future, check it once a month. At the same time, check whether the shielding sleeve between the motor rotor and stator is well sealed.

Why does the demand for submersible slurry pump increase greatly? From the perspective of market demand,HalabujaFire deep well pump, although the absolute number of submersible slurry pumps has not exceeded that of vertical slurry pumps, it has a rapid development momentum, mainly due to the convenience and flexibility mentioned above; In addition, 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.

　　 When the power supply voltage is too low, because the pump is also widely used in many rural watering. In this case, it may be lower than the rated voltage so the current in the stator winding will also be　　The motor ball bearing is damaged.　　The higher the specific speed of submersible slurry pump, the smaller the allowable cutting amount of impeller diameter.
