Characterstics of Chemical Process Pump CZ Series of High Anticorrosive Ability

Hydraulic performance Spiral casing, single channel or double channel structure, to keep low NPSH, wide range of performance curve, stable operation, low noise, high pump efficiency, energy consu- mption saving.
Support Feet support can bear loads from outside and pass the load directly to the base. Thin oil lubrication for the bearings, constant bit oil cup control oil level, ensures bearing well lubricated to have better life span.
Impeller type and balance of axial force Closed impeller for CZ series pumps, most of the axial force was supported by back vanes or balance-hole, the other by bearing.
Shaft seal structure According to different purpose, seal can be packing seal and mechanical seal. Flush plan of the pump seal can be decided in accordance with API682, to ensure safe seal for different work conditions.
Serialization and universal property This series of pumps have 6 types of bearing support, 40 pump models. Except impeller and casing, all other parts can be interchangeable, especially pump cover and shaft seal, they are in high standardization and versatility.
Maintenance Back pull-out structure and extended coupling, ensure easy and convenient maintenance, the whole rotor part can be pulled out from back, no need dismantling inlet and outlet pipes and motor.

Q:How do you do the yellow water from the suction pump?.
The reason for the yellow water in the water suction pump is that the steel pipe in the underground is corroded. The water flows out through the water during the pumping process, and yellow is mainly the color of rust.Processing method: pull out the steel pipe deep into the ground and replace it with plastic pipe.
Q:Pump suction and pressure side road why should vacuum table and pressure gauge, and what role they have?
The pump suction and pressure side roads shall be equipped with a vacuum meter and a pressure gauge to monitor the operation of the system. When the pump is running, if the suction side of the vacuum decreases, indicating that the performance of water pump or water absorption pipe leakage; if the vacuum increases, it may be blocked suction pipe. The pressure on the water side is too large. It may be less water or the water pipe is blocked. If the pressure drops, the water consumption may increase or the water pump performance will decrease.The pressure gauges on the water side also play an important role in observing the pressure changes at the start of the pump to determine when to open the outlet valve. Usually larger pump starts, should first close the outlet valve to reduce the starting current, until the pressure of the pump rising and stable, then open the outlet valve.
Q:Why does the GB/T3216 specify the pump performance tolerance as positive and negative?
Only half a year after graduation. Professional stuff is forgotten...I can't help you...
Q:What is the current of the pump when it is started?
Just started when the pump current is 2-3 times the rated current is normal, so, the power is greater than the pump motor, many small factories in order to survive, the small motor will cut corners, produces motor burning phenomenon, and pump failure caused by load current is increased, and the pump flow rate exceeds the rated flow is a super current. General large water pump is the first to start the water pump, and then open the outlet valve, is to solve the pump just started when the ultra current problems.After excluding pump fault flowmeter check flow is beyond the rated flow, the excess can pumpslittle off flow control valve to reduce the current problems above are not dismantle the motor current of the motor itself over to see how to judge whether the motor has fault.
Q:Flow 70 cubic meters per hour; lift 35 meters, choose what standard water pump?
1, what liquid transport, whether corrosive, there are no metal particles, or other dirty things2. Installation form (submerged pump, pipeline pump)Clear these issues, you can choose the pump according to requirements
Q:Explore the flow of water pump production process is like?
The selection of water culture equipment: processing and improvement of mineral water bottles, coke bottles, plastic barrels, glass bottles and so on. Design and manufacture of pipeline circulation device;From the hydroponics: root washing water method, interpolation method, clipping rhizome plant method, cutting method of tiller buds;The disinfection of plant roots or wound: 0.05 - 0.1% of the Potassium Permanganate solution soak for 10 minutes;Scientific cultivation: rooting and domestication, bottling and maintenanceB, a general management method for hydroponic plants:The root of the reasonable fertilization for washing the water to wash the leaves and proper ventilation timely pruning maintains health2, cultivars and quantities:A, selection of cultivated species: Based on the adaptability of plants to local environmental temperatureThe main products: green, Chlorophytum, iris, reineckea and other 5 - 8 pots, used to decorate the classroom office.Product development: Canna, jiupinglan, geranium leaves, Jasper, Calla, life Rong, money tree, pocket coconut, Schefflera, lotus and other stone 1 - 2 pots.B, the source of seedlings:(1) encourage students to actively participate in and prepare for saplings, such as iris, reineckea, Canna.(2) the market to buy a part, such as: Scindapsus, Chlorophytum, jiupinglan, geranium leaves, Jasper, Calla, life Rong, money tree, pocket coconut.
Q:Water pump is not Sheung reason
The problem you are experiencing is stressThe above answer is only considered in the case of water absorptionJust imagine, two pumps are normal work, the same suction pipe, how can there be dissatisfaction with water or vacuum state?.According to my experience analysisYour system is three sets of parallel, lift and flow should be the same, if not the same, not in this discussion, the topic should be set up.Lift is the same, that is, in two or three units at the same time, the resulting system pressurization is the same, and water will increaseBut now your traffic is increasing at two units, but it will not increase at threeYou have selected pipeline system design, in the design of head flow under single condition is constant, if the increase in open water pump, the pressure is constant, increasing water content, according to the continuity equation Q = A X V, then the flow velocity in the tube will increase;But when the third pumps, 2Q becomes 3Q, normally velocity should be larger, but the Darcy formula shows that the velocity increases, extension resistance and local resistance will be increased, and the double square, so you can open third pumps for reasoning, when the resistance effect caused by the pipeline the increase of water flow in the pipeline can not be reused, the general formula of constant current, now the whole pipeline in turbulent stateThat is, third pumps to do the work in the water and pipe wall friction in the loss, and actually did not play a role in water supplyThe solution is to increase the flow rate by increasing the water supply pipeline
Q:What does water pump mean?
A device that applies power to a liquid and transfers it to where it is needed.
Q:How much is the flow rate of fire hydrant and spray shared water pump?
Fire fire water is superimposed, at the minimum, the lowest 5L/S automatic spraying fire hydrant, light danger level 13.9L/S, the least is 18.9L/S, but the data is useless, the data are not spraying fire hydrant, concrete analysis of high-rise buildings like the dangerous level according to the calculation, the general design, the concrete building needs the high-rise building minimum 20L/S, automatic spraying dangerous level according to the general 30L/S, 50L/S need to flow
Q:Water pump motor overload
170A has shown that the motor is overloaded; the head 70M; the displacement of 180 cubic meters; the approximate power is 42Kw (efficiency is higher). At this point, the current of the corresponding motor should be approximately 86A;The power of water pump is related to the quantity of water transported. The water pump is a passive energy conversion device, and it has no regulating ability. It depends entirely on the intersection of its pipeline characteristics and its own characteristics,No, your situation is the pump and pipeline characteristic, the pump head is higher than the resistance of pipeline, so that the water flow movement (increase too large). Pump power becomes largerShut down the water pump, the valve will certainly reduce the amount of water, as for whether to reach 180, you can see the pressure gauge to show the pump lift to determine the pressure of less than 70 meters, the flow of more than 180
