Proliferation in the use of high pressure coolant systems as a machining aid fostered the development of hongyitengda Right Angle Drill Heads, Spindle Speeders, and Keycutters. Compared to spindle driven heads, hongyi tengda's angle drill heads have two important cost-savings advantages: they are indexable, allowing multi-position machining with one angle head and set-up, and their compact profile allows machining in bores and cavities not accessible to mechanical heads. Right angle head and universal horizontal drill head.

No negative pressure steady flow device
In order to adapt to the modern people's life, improve the quality of domestic water, protect people's health, respond to energy-saving calls, and completely solve the various disadvantages of traditional water supply equipment, the company after market research, launched without pool, no water tank, you can Directly connected to the municipal pipe network pressure, saving investment, significant energy-saving effect, the real secondary water supply equipment without secondary pollution - "no negative pressure steady flow device" to solve the problem of secondary pressure. The biggest difference between non-negative pressure steady flow device and traditional water supply equipment is the different water diversion ways. At present, common diversion ways of water supply equipment are as follows: First, General pumps and reservoirs are arranged above the ground (also some arranged in the basement of the building), the pump base and the bottom of the reservoir is basically the same, the reservoir water level must be higher than the pump outlet vent to ensure that the pump Before starting, the water in the reservoir can be automatically poured into the pump chamber and the air in the pump chamber can be emptied. This installation, the pump inlet generally need to install a valve, when the pump failure needs to be removed for repair or replacement, the valve can be closed to prevent water leakage within the reservoir. Second, the way the reservoir sucked on the water diversion Suction on the water diversion, the reservoir is generally built below the ground, and the pump is located on the ground, the highest reservoir water level below the pump inlet, therefore, the reservoir of water Can not be automatically poured into the pump chamber, in order to make the pump work properly, the pump must be manually filled with water before the pump and the pump suction pump cavity, the pump cavity exhausted air, so the water pump suction pipe bottom End of the need to install the end of the valve, but because some of the bottom valve sealing is not very good or the sealing can not be sustained, coupled with the foreign body into the bottom valve so easy to close the valve at the end of lax, so this suction on the water diversion pump layout more The less the water flow, most of them are retrofitted with water diversion irrigation. Due to the installation of diversion irrigation, no artificial irrigation and no bottom valve, no need to consider the seepage leakage, so the pump operation reliability is much higher. Taking into account the impact on the pump suction and seepage water leakage problems, the suction pump suction arrangement is generally not installed before the water pump inlet valve, check valve and other valves. Third, the municipal pipe network direct connection If the pump directly connected to the municipal pipe network, make full use of the original pressure of the municipal pipe network, energy-saving effect is good, do not need to build reservoirs, directly connected with the municipal pipe network, no water quality secondary Pollution, but China's urban water supply regulations in order to prevent the surrounding residents have an impact on water, does not allow life, production water pump installed directly in the municipal pipe network pumping. In the pump inlet and municipal pipe network between the addition of negative pressure steady flow device, the water supply equipment can be connected in series with the municipal water supply pipe without negative pressure, it will not affect other users of water, making the pump from the municipal pipe network In the direct suction does not produce negative pressure, and can also make full use of the original pressure of municipal pipe network, is a form of energy efficient water supply, won the majority of users of all ages. Due to the fact that the water level in the steady-flow device without negative pressure is higher than that of the pump vent, the water pump can realize self-priming. When the water supply in the municipal pipe network is sufficient, the vacuum suppressor on the non-negative pressure steady flow device automatically drains the air in the tank, And the water supply to the pump, no negative pressure steady flow device is sealed, the municipal pipe network pressure directly superimposed on the pump inlet, for the pump use; when the municipal pipe network when the water supply is insufficient, due to water pump will produce negative pressure, then The vacuum suppressor automatically eliminates the negative pressure so that the atmosphere in the steady flow tank is always maintained at atmospheric pressure so as not to affect the water shortage in the surrounding users, resulting in the water level controller stopping the operation of the water pump and displaying a water shortage indication. Equipment advantages: No need to build the pool, do not set the water tank, taking up less space, saving investment. Equipment directly connected with the municipal pipe network, the water quality is truly secondary pollution, greatly improving the quality of water supply. Directly connected with the municipal pipe network, you can make full use of municipal pipe network pressure, the pump only to the municipal pipe network and the pressure required by users make up, and municipal pipe network pressure to meet user requirements, the device automatically stop working, so energy efficient. Negative pressure tank automatic operation, municipal water pipe network equipment automatically shut down, automatic water machine boot, power supply municipal pipe network blackout non-stop. Water-saving effect, closed operation, no leakage, overflow phenomenon. Save operating expenses, because no pool, no cleaning, disinfection. Negative pressure steady flow device is mainly used in the municipal pipe network sufficient water supply pressure but can not meet the requirements of the case, but if the user needs a certain amount of water storage due to peak water flow should be increased by the volume of the canister to solve. When the water supply of municipal pipe network meets the user's water consumption, the volume of the steady flow tank can be selected according to the minimum volume. When the water supply of the municipal pipe network can not meet the user's water requirement, the volume of the steady flow tank can be estimated according to the following formula: V = (Q2 - Q1) × TV - volume of the steady flow compensator Q1 - influx of municipal pipelines (m3 / h) at peak day of peak water usage Q2 - water consumption of users at peak day of peak water consumption (m3 / h); T - duration of maximum water peak.
