The working principle of PVDF vertica linline pump: Vertical pump is a kind of centrifugal pump, mainly relying on centrifugal principle to complete liquid transportation. Due to the function of the independent impeller structure, the internal pressure can be balanced and the liquid can be completely sealed. The structural feature of the impeller is that the blades are installed beside the impeller, and the opposite blade is on one side with a protruding ring. When running, the liquid flowing to the shaft (due to internal pressure) will be blocked by the back pressure of the protruding ring and the opposing blades. When the motor is running, the centrifugal force causes the liquid seal to automatically open, resulting in no Friction point state. When the motor stops running, after the centrifugal force disappears, the liquid seal itself elastically bounces back to seal, preventing the chemical gas from rising, preventing the motor and bearings from being corroded by the chemical gas, and prolonging the service life of the motor and pump.

Saiken Pump Industry is a manufacturer and supplier of lobe rotor pumps
The lobe rotor pump is a self-priming pump , valveless, positive-discharge pump. The flow rate is proportional to the speed, and it can transport all kinds of viscous or particle-containing media. The pump structure is compact, the shearing force to the medium is small during the conveying process, the operation is stable, and the vibration is small. The lobe rotor pump has a wide range of uses. It is especially suitable for conveying mud and other media containing solid particles, as well as media with strong abrasiveness and sensitivity to pulsation. The rotor lobe pump is a self-priming, valveless, positive-discharge pump. The two parallel shafts are driven by synchronous gears to rotate relatively, and the air in the inlet is exhausted to form a vacuum so that the medium is sucked in, and the medium in the continuous operation cavity is pushed to the outlet end. The pump delivery direction can be reversed by changing the rotation direction, so as to achieve the purpose of two-way delivery of a pump. The rotor error of the cam rotor with high precision CNC machining is extremely small. The rotor of the rotor pump seals the inlet and outlet perfectly, and the suction range of the pump can reach 9.0 meters. The material of the rotor can be selected according to the characteristics of the conveyed medium. We have a variety of material options for rotors, including wear-resistant elastomers, hard steel, stainless steel, etc. Space occupation: The design of the rotary lobe pump is exquisite and compact, and it can be installed smoothly in an extremely limited space. The design of the flange and the placement of the motor can be adjusted according to the site conditions to adapt to the customer’s space constraints. Pump housing: The pump casing is integrally cast with very small error. Materials include cast iron and stainless steel. There are replaceable protective liners on the front, rear, left and right to reduce the cost of accessories. The surface of the liner can be hardened to increase wear resistance.
The working principle and characteristics of the lobe rotor pump
Cam rotor pump, as a fluid conveying technology, is a non-contact, rotary positive displacement pump. It is mainly composed of circular arc pump casing, rotor, front and rear plates, mechanical seals and synchronous gearboxes and other accessories. Its working principle is the same as that of a Roots blower. The two rotors move relative to each other under the drive of two parallel shafts. A continuous sealed cavity is formed between the rotor and the pump casing, and the medium filled in the cavity is continuously rotated by the rotor. Push from the end to the outlet end to complete the conveying of the medium. The rotor is divided into two types: straight tooth type and spiral type. The number of blades is 2, 3, 4 and 6 blades. Under the pressure of the rotor pump, the flow rate and the speed are strictly linear. Rotor pumps are widely used in water treatment, chemical industry, shipbuilding, food, petroleum, biogas and other fields due to their large flow, small size, and good characteristics. Especially in recent years, many screw pumps have been gradually replaced by cam rotor pumps in various sludge conveying system processes in the water treatment field. The performance of the cam rotor pump is very stable, and the dehydrator system is operating normally; and the feed pump motor is changed from 30kW to 22kW to meet the process requirements, so the energy consumption is also reduced; at the same time, the pump frequency is about 45Hz at the pump’s large flow point. The rated frequency of the pump design is reached, so the performance of the pump is relatively stable. Due to the relatively large wear of the pump in the relatively high-pressure stage, it is recommended that the time under high-pressure working conditions should not exceed 60min to achieve a longer service life. When designing the inlet and outlet pipelines of the lobe rotor pump, especially for the working conditions with relatively high pressure, try to use straight pipes at the inlet and outlet of the lobe rotor pump to avoid elbows, so that the pipeline vibration is less and more reasonable. Add piping piers and buttresses at elbows, tees, etc. to strengthen the pipe support, and at the same time add flexible joints at appropriate locations to resonate. This is a problem that needs to be paid attention to when the cam rotor pump is used in relatively high pressure conditions. Cam rotor pump manufacturers and suppliers
There are many types of centrifugal pumps, but there are so many different types of centrifugal pumps. How to choose a centrifugal pump that suits your needs? What kind of understanding should be done before choosing.
The following describes the multiple uses of self-priming pumps: There are many structural types of self-priming pumps. Among them, the working principle of the external-mixing self-priming pump is that the pump casing is filled with water before the centrifugal pump is started (or there is water in the pump casing itself). After starting, the impeller rotates at a high speed to make the water in the impeller channel flow to the volute. At this time, the inlet forms a vacuum, so that the water inlet check door opens, and the air in the suction pipe enters the pump and reaches the outer edge through the impeller channel. On the other hand, the water discharged into the gas-water separation chamber by the impeller flows back to the outer edge of the impeller through the left and right return holes. The water flowing back from the left return hole is ejected into the impeller channel under the action of pressure difference and gravity, and is crushed by the impeller, mixed with the air from the suction pipe, and thrown to the volute. The submersible pump is corrosion-resistant The pump acid-resistant pump, the fire pump moves in the direction of rotation. Then it merges with the water flowing from the right backwater hole and moves along the volute. Because the liquid continuously impacts the cascade in the volute and is constantly broken by the impeller, it is stirred and mixed strongly with the air, and the mixture of natural gas and water is energized, and the negative gas and water cannot be separated by continuous activity. The mixture is peeled off by the tongue at the exit of the volute and enters the separation chamber along the short tube. The air in the separation chamber is separated and discharged by the outlet pipe, while the water still flows to the outer edge of the impeller through the left and right return holes, and is mixed with the air in the suction pipe. Repeated cycles like this, gradually exhausting the air in the suction pipeline, allowing water to enter the pump, completing the self-priming process. Sewage pump self-priming pump oil pump
The working principle of the internal mixing self-priming pump is the same as that of the external mixing self-priming pump. The difference is that the return water does not flow to the outer edge of the impeller, but to the inlet of the impeller. When the internal-mixing self-priming pump is started, the return valve at the front and bottom of the impeller must be opened to make the liquid in the pump flow back to the inlet of the impeller. Under the action of the high-speed rolling of the impeller, the water mixes with the air from the suction pipe to form an air-water mixture and discharge to the separation chamber. Here air is discharged and water returns from the return valve to the impeller inlet. Repeat this until the air is exhausted and the water is sucked up.
The self-priming height of the self-priming pump is related to factors such as the front seal clearance of the impeller, the number of revolutions of the pump, and the liquid level of the separation chamber. The smaller the front seal clearance of the impeller, the greater the self-priming height, which is generally taken as 0.3~0.5 mm; when the clearance increases, the pump’s head and efficiency will decrease except for the decrease of the self-priming height. The self-priming height of the pump increases with the increase of the circumferential speed u2 of the impeller, but when the maximum self-priming height is reached, the number of revolutions increases and the self-priming height no longer increases. At this time, the self-priming time is only shortened; when the number of revolutions When descending, the self-priming height will follow. Under the condition that other premises remain unchanged, the self-priming height also increases with the increase of the water storage height (but it cannot exceed the optimal water storage height of the separation chamber). In order to better mix the negative air and water in the self-priming pump, the blades of the impeller must be smaller to increase the pitch of the cascade; and a semi-open impeller (or an impeller with a wider impeller channel) should be used, which is more convenient The backwater shoots deeply into the impeller cascade.
