How to solve motor failures of a cement pump machine

图片
Reasons for and solutions to pumping failures of a  cement pump machine  are as below.   The first reason is that the main motor fails to reach the specified speed. If you press the start button of the main motor, the motor runs, but it fails to reach the specified speed. When the star connection method is converted to the triangle connection method, the automatic shutdown is performed.   You should first check whether the normal capacity of the power supply voltage is sufficient (the capacity of the transformer is generally 1.15 times of the calculated load), and then determine whether the wire diameter of the power supply line meets the requirements by calculating and measuring the voltage at the start, Ensure that the voltage drop is within the specified range (the allowable voltage drop on the line is generally no more than 5%). If the voltage drop is too large during starting, increase the diameter properly.   Improper operation and failure of the hydraulic system...

Tips in purchasing a brick making machine concrete block

图片
  Most  brick making machine concrete block  suppliers would have a detailed communication about your specific plan in concrete brick factory building. Then they will list all possible models for your reference, together with weaknesses and strengths of each model. Here you should consider, before making a final decision, your budget, expected production scale, the supplier’s service and integrated performance of a machine. Details are followed as below.   1. Do well in "Model Matching". Before buying a cement  brick making machine , it is best to choose a suitable model based on the desired output and the size and space of the installation site. It is necessary to remind everyone that consumers should treat merchants' persuasion rationally, because many merchants will recommend some high-power models with high prices to obtain more profits, but large models may not be suitable for you.   2.

China concrete pump truck price

图片
  China  concrete pump truck price  is determined according to the model of the truck. With a pump truck the ready mix concrete is powered by the hydraulic system and pumped to the construction site through the boom. A pump truck features high flexibility, simple structure, full hydraulic operation, easy operation and high efficiency, fast construction and good quality, very suitable for concrete construction in narrow spaces.   In China the concrete pump truck price is generally between 300000 and 900000RMB. A Concrete pump truck is a kind of machinery that uses pressure to continuously transport concrete along the pipeline, which is composed of pump body and conveying pipe. According to the structure, it can be divided into piston type, extrusion type and water pressure diaphragm type. The pump body is installed on the car chassis, and then equipped with a retractable or flexible distributing rod to form the pump car.   Not a few factors influence the price of a  C...

Concrete batching plant layout plan

图片
Concrete batching plant layout plan  should take site selection and reasonable design of the area into account. Details are as below. A. Site Selection First of all, it is crucial to choose a concrete production site near from main highways and roads. Solid raw materials, including aggregates, sand and cement, take up 90% of all raw materials, and their delivery cost prove to be a huge share in production cost. The nearer the site is from factories of these materials, the lower the delivery cost. Second, water is second only to solid materials in consumption. It’s used not only in concrete production but also in daily life of people managing the site. Therefore, the site must be located in a place with rich water resource. Third, electric equipment should be designed as reasonably as possible to cater for local voltage and electric devices. Only in this way can you reduce electricity consumption as much as possible. Fourth, the site should be away from neighbourhood ar...
