Rotate the coupling of the acid resistant pump by hand

The lining layer of Dalian acid resistant pump is made of plastic. Plastic pumps are generally single-stage, volute, and radially divided structures. The impeller of plastic water pumps can be divided into three types: open, semi open, and closed. Generally, closed impellers are suitable for conveying media without solid particles, while open and semi open impellers can also transport media containing solid particles. The impeller is divided into two types: integral and lining.

The overall impeller strength is low and can only be used for small pumps. The lining impeller is embedded with metal parts, so the strength of the impeller is relatively high. Realize the reuse of water resources and accelerate the construction and renovation of urban sewage treatment facilities. The existing urban sewage treatment facilities should be renovated according to local conditions and meet the corresponding discharge standards or recycling requirements by the end of 2020. As the scale of sewage treatment continues to grow, the pump and valve industry has also been driven.

According to relevant information, in the investment of sewage treatment equipment, water pumps account for about 15% of the total investment in mechanical equipment. Calculated proportionally, the demand for pump products in the urban sewage treatment field will be around 60 billion yuan, and there will be nearly 40 billion yuan in market demand in the next three years, with a good market prospect. Before installing the vacuum pump and compressor, rotate the coupling by hand.

To confirm whether there is any jamming or other damage inside the pump. Installation of pipeline between vacuum pump and gas water separator: The exhaust pipe of the vacuum pump or compressor is connected to the inlet pipe of the gas water separator. At the flange connection of the pipeline, gaskets should be used to ensure reliable sealing. A storage valve should be installed on the inlet pipe of the vacuum pump or compressor.

Install a pressure gauge between the exhaust pipe and the valve. The threat of potential competitors in the acid resistant pump industry poses a challenge to those enterprises that may enter the industry and participate in competition. They will bring new production capacity, share existing resources and market share, resulting in increased production costs, intensified market competition, decreased product prices, and reduced industry profits.
