Pump valve leak reasons after the maintenance requirements:
Gear pump gear pumps in all belong to the more excellent quality and have a special range of applications. However, stainless steel pumps also have some unexpected malfunctions at work, such as downtime. We need to analyze the main reasons for downtime, so as to avoid unnecessary damage to the machine in the future. Downtime is mainly caused by the failure of the mechanical seal.
First, the performance of the pump valve failures are mostly leaks, leaks for the following reasons:
â‘ static and dynamic ring seal surface leakage, mainly due to: face flatness, roughness does not meet the requirements, or scratches the surface; between the end of the particulate matter, resulting in both ends can not be the same run; installation is not in place, the way is not correct.
â‘¡ compensation ring seal leakage, mainly due to: gland deformation, uneven pre-tightening; installation is not correct; seal quality does not meet the standards; seal selection wrong.
Second, gear pump stop running after the request:
â‘ transport easy to crystallize, easy to coagulate, easy precipitation and other media pump, stop the pump to prevent clogging, and timely flush with water or other media pumps and pipes.
② high-temperature pump should be stopped according to the provisions of technical documents, after parking should be partial 20 -30 30min half a turn until the pump temperature dropped to 50 ℃ so far.
â‘¢ cryogenic pump parking, when no special requirements, the pump should always be filled with liquid; suction valve and the discharge valve should be kept normally open state; the use of double-end mechanical seal of the cryogenic pump, liquid level controller and seal the liquid seal chamber The pump grouting pressure should be maintained.
â‘£ Centrifugal pump should stop running after the pump population valve, to be cooled and then turn off the auxiliary system valves. Exhaust the liquid stored in the pump to prevent corrosion and cracking

Concrete Pole Spinning/Centrifugal Machine:
Concrete Pole Spinning/Centrifugal Machine is mainly apply to produce High strength centrifugal technology Prestressed Reinforced concrete pole(SPC pole) by spinning formed. According to customer's effeciency request, there are Single wheel spinning machine and Double wheel spinning machine at customer's option, it is equipped with a stepless speed-variation motor and a control panel, it works smoothly and its speeder is of wide-range. Its box base is sturdy and durable and easy for installation.
Spinning Machine's Advantages:
1. Unique "slot" design, change the screw limit between the bearing support and the base plate with the card slot and bolt limit. Both up and down sides of the spinning machine panel, undersurface and two sides of bearing support go through fine machining. Though the process is complex, it makes it more solid during high-frequency vibration of bearing support and the floor. Repair and replacement also have interchangeability.
2. Connection shaft is whole shaft, to avoid stress concentration brought by shaft diameter changes, resulting in the phenomenon of "shaft-broken".
3. The limit side of the support wheel is removable. It is convenient for users to replace.
4. Frequency-conversion cabinet of spinning machine records process parameter of each pipe and output reports, provides the office computer data communication interface.
