CYZ self-priming centrifugal pump features:
The pump is a self-priming centrifugal pump. The utility model has the advantages of simple structure, convenient operation and maintenance, stable operation, large displacement, high efficiency, convenient adjustment, strong self-priming ability, wide application range, and the like.
The use of CYZ self-priming centrifugal pump:
Used to transport petrol, kerosene, diesel, aviation kerosene and other petroleum products. The medium temperature is -20°C～+80°C. It is an excellent ship loading and unloading oil pump. It can double as a submerged pump. It is also suitable for the oil transportation of oil storage devices such as land oil depots and oil tankers. Can also be used to transport seawater, fresh water and so on.
CYZ self-priming centrifugal pump structure type:
The structure of the pump body with the shaft and the liquid is used. The pump body is composed of a suction chamber, a liquid storage chamber, a vortex chamber, a liquid return hole, a gas-liquid separation chamber and the like. The pump bearing uses a single row radial ball bearing. A cooling chamber is provided at the bottom of the bearing body of some pumps. There are seal rings in the high and low pressure areas of the pump. The shaft end uses a mechanical seal.
Self-priming centrifugal pump consists of six parts: impeller, pump body, pump shaft, bearing, sealing ring and stuffing box.
The basic structure of the self-priming centrifugal pump:
1. The impeller is the core part of the self-priming centrifugal pump. Its rotational speed is high and the blades on the impeller play a major role. The impeller passes the static balance experiment before assembly. The inner and outer surfaces on the impeller are required to be smooth in order to reduce the friction loss of the water flow.
2. The pump body is also called the pump housing and it is the main body of the pump. It plays a supporting and fixing role, and is connected with the bracket that mounts the bearing.
3, the role of the pump shaft is to connect the shaft and the motor, the motor torque transmission to the impeller, so it is the main component of the transmission of mechanical energy.
4. The bearing is a member that is sleeved on the pump shaft to support the pump shaft. There are two kinds of rolling bearings and sliding bearings. The use of butter as a lubricant for rolling bearings should be appropriate. Generally, 2/3 to 3/4 of the volume will be too hot, too little noise and heat! Sliding bearings use transparent oil as the lubricant and add to the oil level line. Too much oil must seep and float along the pump shaft. Too few bearings must be overheated and burned to cause an accident! The temperature of the bearing during the operation of the pump is up to 85 degrees. Normally the temperature is about 60 degrees. If it is high, the cause must be found (whether there is any impurity, whether the oil is black, whether it is in water) and it is handled in time!
5, the sealing ring, also known as leakage reduction ring. The gap between the impeller inlet and the pump casing is too large. As a result, the water in the high-pressure area of ​​the pump flows to the low-pressure area through this gap, affecting the pump output, and the efficiency is reduced! If the clearance is too small, it will cause friction between the impeller and the pump casing. In order to increase the return resistance to reduce the internal leakage and delay the service life of the impeller and the pump casing, a seal ring is installed at the inner edge of the pump casing and the impeller foreign aid joint, and the seal gap is preferably maintained between 0.25 and 1.10 mm.
6. The stuffing box is mainly composed of packing, water sealing ring, packing tube, packing gland and water sealing tube. The function of the stuffing box is mainly to close the gap between the pump casing and the pump shaft, so that the water in the pump does not flow out and the outside air does not enter the pump. Always keep the vacuum inside the pump! When the friction between the pump shaft and the packing generates heat, it is necessary to rely on the water seal tube to live in the water seal ring to allow the packing to cool! Keep the pump running properly.
