The tofu pudding pump is a small piece of equipment used for processing tofu pudding. The following is its related introduction:
Common Types and Working Principles
Gear Pump: Through the meshing of gears, the tofu pudding is transported from the inlet to the outlet under the drive of the gears. It has characteristics such as stable flow and relatively high pressure, and is suitable for tofu pudding processing sites that require a certain transportation distance and height.
Flexible Vane Pump: There is an eccentric bump in the pump chamber. When the flexible vanes move away from the eccentric bump, the volume between the vanes continuously increases, creating a vacuum, so that the tofu pudding is continuously sucked into the inlet part of the pump chamber. When the flexible vanes rotate, the liquid is taken from the suction part of the pump chamber to the discharge part. When the flexible vanes touch the eccentric bump again, they bend and accompanied by a squeezing action, enabling the tofu pudding to be discharged from the pump chamber continuously and without pulsation, thus completing the whole process of suction and discharge.
Piston Pump: It includes a piston cylinder with an inlet and an outlet for the tofu pudding, as well as a piston that reciprocates up and down inside the piston cylinder. The piston has a layered structure, which from top to bottom consists of an upper elastic pad, a rigid pad, and a lower elastic pad. Multiple through holes are opened on the rigid pad and the lower elastic pad. The outlet for the tofu pudding is set on the side wall of the upper part of the piston cylinder, and the inlet is set on the bottom wall of the piston cylinder, and a one-way valve is installed at the inlet. The increased movement range of the piston inside the piston cylinder improves the efficiency of transporting the tofu pudding, and through the multiple through holes on the rigid pad and the lower elastic pad, the tofu pudding can be crushed and mixed evenly.
Self-priming Pump: It adopts a pump body structure with axial liquid return. The pump body is composed of a suction chamber, a liquid storage chamber, a scroll chamber, liquid return holes, a gas-liquid separation chamber, etc. After the pump starts normally, the impeller sucks in the liquid stored in the suction chamber and the air in the suction pipeline together and completely mixes them inside the impeller. Under the action of centrifugal force, the liquid, carrying the gas, flows towards the outer edge of the scroll chamber, forming a certain thickness of white foam belt and a high-speed rotating liquid ring on the outer edge of the impeller. The gas-liquid mixture enters the gas-liquid separation chamber through the diffuser pipe. At this time, due to the sudden decrease in flow velocity, the lighter gas is separated from the mixed gas-liquid, and the gas continues to rise and is discharged through the outlet of the pump body. The degassed liquid returns to the liquid storage chamber and enters the impeller again through the return hole, mixes again with the gas sucked in from the suction pipeline inside the impeller, and under the action of the high-speed rotating impeller, flows towards the outer edge of the impeller again. This cycle repeats continuously, and the air in the suction pipeline is continuously reduced until the gas is completely sucked out, completing the self-priming process, and then the pump can start normal operation.
Characteristics
Hygiene: Most of them are made of stainless steel materials, such as SUS304 and AISI316 stainless steel, etc., which meet the 3A and GMP standards, ensuring the hygiene and safety of the tofu pudding during the transportation process and preventing pollution.
Energy Saving: Different types of tofu pudding pumps have certain advantages in terms of energy saving. For example, the rotor-type tofu pudding pump has a structural design that results in lower energy consumption when transporting tofu pudding, reducing production costs.
High Efficiency: With a small size and large flow design, it can transport a large amount of tofu pudding in a relatively short time, improving the production efficiency of tofu pudding.
Pulsation-free Transportation: It can keep the flow and pressure of the tofu pudding stable during the transportation process, avoiding problems such as the fragmentation or unevenness of the tofu pudding caused by pulsation.
Strong Self-priming Ability: Some tofu pudding pumps have a relatively high self-priming ability without liquid, which can be as high as five meters of water column, and can quickly and effectively suck the tofu pudding into the pump for transportation without the need for additional auxiliary equipment.
Applicable Scenarios
Bean Product Processing Factories: It is used to transport the produced tofu pudding from production equipment to packaging or storage areas, realizing automated production and improving production efficiency and product quality.
Breakfast Shops and Snack Bars: It helps merchants quickly and conveniently transfer the tofu pudding from the production containers to the sales containers, ensuring the freshness and taste of the tofu pudding and meeting the needs of customers.
Canteens and Restaurants: It can supply tofu pudding in a timely and stable manner, ensuring that delicious tofu pudding can be provided to a large number of customers even during the peak dining period.
Maintenance
Routine Inspection: Regularly check whether there is any looseness in the pump body, pipelines and joints. Turn the pump by hand to check whether it is flexible. Jog the motor to check whether the rotation direction of the motor is correct.
Control of Operating Parameters: Try to control the flow and head of the pump within the range indicated on the nameplate to ensure that the pump operates at the optimal efficiency point, obtain better energy-saving effects, and at the same time extend the service life of the pump.
Cleaning and Rust Prevention: After use, the pump body should be cleaned in time to prevent the residual tofu pudding from clogging the pump chamber or corroding the pump body. If it is not used for a period of time, the accumulated water in the pump should be drained completely, the main components should be wiped clean, rust-proof oil should be applied, and it should be placed in a ventilated and dry place for standby.
Troubleshooting: When the motor malfunctions, for example, if the motor can operate but the speed is slow, the casing is overheated, and there is a burning smell, it may be caused by a short circuit in the motor. The motor should be disassembled to check the severity of the damage and then repaired. If there is a lot of noise and vibration during operation, most likely the bearings are damaged or the fit between the bearings and the casing is improper. It is necessary to disassemble the motor for inspection. If the bearings are damaged, they should be replaced. If the bearings "run out of round" on the outer circle, the mating surface of the pump casing can be treated by knurling. If the bearings "run out of round" on the inner circle, the worn part of the motor shaft can be treated by knurling. If the wear is severe, the method of first build-up welding and then turning can be adopted for repair.
