The centrifugal pump knowledge is all here!

The basic structure of the centrifugal pump is composed of six parts are impeller, pump body, pump shaft, bearing, sealing ring, packing box. 1, the impeller is the core part of the centrifugal pump, its speed is higher than the force, the blade on the impeller plays a major role, the impeller in the assembly before the static balance experiment. The inner and outer surfaces of the impeller shall be smooth to reduce the friction loss of water flow. 2, the pump body is also called the pump shell, it is the main body of the pump. Plays a supporting and fixing role, and is connected with the bearing bracket. 3, the function of the pump shaft is to connect the coupling and the motor, the torque of the motor to the impeller, so it is the main part of the transmission of mechanical energy. 4. Plain bearing uses transparent oil as lubricant and lubricates it to the oil level line. Too much oil to seep out along the pump shaft, too little bearing and overheating and burning cause accidents! During the operation of the pump, the temperature of the bearing is 85 degrees, and the general operation is about 60 degrees.
Northern winter water pump anti-freezing, thawing measures

Northern winter water pump anti-freezing, thawing measures

2021-02-26 14:34:39
Winter comes, the air is dry and cold, and the temperature drops to below zero. Are you worried that the water pump in use is easy to freeze or even the pump body is frozen and cracked under low temperature conditions, just like in previous years? In view of this situation, xiaobian summed up the following measures for anti-freezing water pump maintenance. 1, add insulation material for the pump to prevent the pump from freezing; (Water pumps also need to wear "clothes", exposed in the cold outdoor work, we can use cotton wool, towels, waste clothes and other clothes to wrap exposed outdoor water pumps, water pipes, faucets and other water facilities, to achieve thermal insulation effect.) 2, the pump body will not be temporarily empty, when using water, to prevent the pump freezing freezing pump: 3. The doors and Windows of the basement pump room and those without hVAC are closed. The unfinished basement pump room and wind tunnel are blocked. 4. Because all pumps of our company are delivered with hose pressure test, there is water in the pump body and management valve of the factory equipment. If the equipment is not installed, please be sure to take drainage measures to prevent freezing and cracking. 5. If the pump is frozen, do not start the pump. Use hot water or boiled water to pour into the pump to internalize the ice, or heat the pump shell.
Shanghai Municipal Bureau of Quality supervision: 6 batches of water pump products have been found unqualified

Shanghai Municipal Bureau of Quality supervision: 6 batches of water pump products have been found unqualified

2021-02-26 14:33:36
The Shanghai Municipal Bureau of Quality and Technical Supervision announced on its website on Monday the results of a random inspection of 70 batches of water pump products in 2015. After the inspection, six batches failed to pass the inspection. According to the introduction, water pump is listed in the national industrial products production license catalogue of products. There are a total of 74 certified manufacturing enterprises in Shanghai, of which 70 have actually received products this time, and another 4 have not received samples due to production suspension and other reasons. According to gb10395.8-2006 "Agricultural and forestry tractors and machinery Technical requirements part 8: Drainage and irrigation pumps and pump units" and other national standards and related standards, the following items of submersible pump products were tested: Overload protection, grounding measures, insulation resistance and electric pump leads to cable and stator winding resistance to voltage, electric pump efficiency, rated capacity at the time of the head, electric pump input power, pump shaft power, power factor, temperature rise within the limit, motor stator cavity water (gas) pressure test, the operation instruction content, sign/sign firmly, production license; The following items of centrifugal pump have been tested: specified point efficiency, specified point flow, head, NPSH, leakage, unit operation, vibration, noise, appearance quality, mark, license mark.

近年来，受到国内良好的投资环境以及基础建设政策的不断深化，我国泵阀行业将引来持续增长的发展新机遇。虽然，国内泵阀行业前景乐观，但也存在一些不利因素。 水泵性能的技术参数有流量、吸程、扬程、轴功率、水功率、效率等;根据不同的工作原理可分为容积水泵、叶片泵等类型。容积泵是利用其工作室容积的变化来传递能量;叶片泵是利用回转叶片与水的相互作用来传递能量，有离心泵、轴流泵和混流泵等类型。 钢铁作为泵阀产业的原材料，在环境压力逐渐加大的今天，其亟待转型。钢铁行业将会面临减产的危险，减产将导致短期内钢价上调，导致泵阀行业的成本提高,造成泵阀行业短期的价格波动。因此泵阀行业也会受到较大的影响。
