The difference between the vertical slurry pump and the submersible slurry pump The working position of the vertical slurry pump is different. The vertical slurry pump is partially immersed in the pit and cannot be completely immersed in the liquid level. The submersible slurry pump can be completely immersed (including the motor part) below the liquid level; Use of motor for vertical slurry pump　　.Henri de Castries ,　　QW (WQ) submersible non blocking sewage pump shall be carefully inspected before operation? Whether the cable is damaged, whether the fastener is loose or dropped, and whether the pump is deformed or damaged during transportation,Henri de Castries Submersible sewage pump, storage and equipment.　　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,　　About %), and motor power p=i × U indicates that high power and current will increase.　　Pump. In addition, the submersible slurry pump is mainly characterized by 'slurry', which is wear-resistant and particle passing.　　The submersible slurry pump is a kind of submersible pump which is connected with the motor and works underwater at the same time. In addition compared with horizontal slurry pump and vertical slurry pump, submersible slurry pump has the great advantage of flexibility and convenience, and is more suitable for various working conditions. The important technical points of submersible slurry pump are its motor and

　　 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.　　 Use a V insulation resistance meter to measure the insulation resistance between phases and phase to ground of the electric pump motor and the value shall not be less than m Ω. Otherwise, the motor stator winding shall be dried, and the drying temperature shall not exceed ℃.　　 install a valve to inject water at the water inlet and outlet. This method is to install a valve on the water inlet pipe of the submersible slurry pump and connect the water pipe to inject water into the pump. This is a common and simple method.Inspection standard,　　The high-efficiency slurry pump has three characteristics: first, the slurry pump has high operation efficiency and low loss.　　Rate loss, so shaft power = effective power + lost power.　　 the water pipe shall be short, 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 mixing impeller and other main flow passage parts are made of high wear-resistant materials, which are wear-resistant, corrosion-resistant, non clogging and have strong sewage discharge capacity, and can effectively pass through large solid particles. It is not limited by suction range,Henri de Castries Vertical slurry pump, with high slag suction efficiency and more thorough desilting. No auxiliary vacuum pump is required and the investment is lower. nothingmiddleman,　　Second, the service life of the flow passage parts of the pump is relatively long, the diameter of the impeller after cutting shall not be less than % of the diameter of the standard impeller, otherwise the of the pump will have a very adverse change. After the impeller of the slurry pump is cut, the flow area in the pump body increases, which makes the flow increase after the impeller is cut.Henri de Castries ,　　The pump can often be selected according to the specific requirements of lift, flow and liquid delivery. The flow range of the delivered liquid is - L / s, the pressure range is .- MPa, and the diesel engine speed range is - rpm. Features: water pump, high automation and performance　　 First of all, we need to know that submersible pumps generally operate in water. In fact, most of the pumps are suitable for conveying some relatively clean media, and their impellers are generally in a closed state. However, one of the media conveyed by sewage pumps may　　 We also need to make choices according to local conditions when we make purchases at ordinary times. For example, the head of the centrifugal pump itself is relatively high, so it is effective when it is used in many mountainous areas
